G.Skill 2GBZX DDR400 2-3-2-5 Test

[x-men]

Your right G.S Technican for this price here in germany its an absolut fantastic ram. Except the divider problem it is for about 20~30 Euro more than a normal noname ram-kit with cas3 a super cheap ocing ram.

As you work for GSkill which bios would you recommend for this ram. I read the last weak so many threads about this ram with so many bios recommendations. I get by time a little bit confused.

Can't you get it a bit higher on divider when you loosen the timings a bit?
I am getting worried when i look at your results since i really hope that i can keep running 295 HTT.

[x-men]

For me it is kinda curios. No matter how loosen i set the timings I wont get into windows at 300 htt. It just stops booting after the nvidia raid screen appeared anf it should back up cmos.
If I plug in my twinmos bh-5 with low divider everythig works fine upto 310~320 htt. Probably it is cpu memory controller related as my twinmos kit is only 1 gb.

Hmm i could live with 290 HTT but less would meke me cry. :)

[x-men]

Probably on weekend I will test the majority of bioses for the dfi and look if there is one for my combination of hardware to suit 300+ htt and low divider.
But as I said before for his price it is an absolut superb ram and the first 2 Gb kit i installed and running 250+ at 1:1 absolut stable.

[Jessfm]

As usual.
Only place that has it in UK area wants $332 for them :slapass:

I've already tried 623-3, 632-1, 704-1, 510-1, 704-2bta. They all workt he same.

[mucker]

I am going with a ZX kit. I plan on using it with my Opteron 146 and DFI nF4 Ultra-D. I am not expecting miracles, but I am hoping to run 280 HTT with a 166 divider (233 fsb) at 3-3-2-5. I would be very happy with that result. We shall see.....

m :)

[demenion]

I have a set of ZX's coming in.. will let you know how they OC. looking for 290-300 HTT on 166 divider.

[Metalkobra]

Nobody has yet to answer my other question though ;), is it worth it to make the switch from 1gb to 2gbs? I mean what real performance increase will I see with more memory? what can I expect from 2x1gb as opposed to 2x512?

Entirely depends on your application(s).

[Metalkobra]

Well, I do some gaming, CS:S, ROSE online, o2jam, F.E.A.R, etc, and i run things like Yahoo and AIM in the background...

[mucker]

I just got my ZX kit, very impressed :woot:

Popped them in about an hour ago. Currently, I am at 2600 MHz (260x10) on the cpu and 9:10 memory at 2.5-3-2-5-1T @ DDR472 @ 2.7v

I plugged the exact numbers in from Mr. GSkill USA (1st thread) and stable instantly. So far memtest, pi 1M, OCCT, and hard gaming stable.

DFI nF4 Ultra-D, 623-3 official, orange slots

Extremely happy to replace my Mushkin TCC5 with the G.Skill ZX...

Thanks G.Skill, you'll have my business, as well as my clients....

UPDATE: The sticks pass memtest with flying colors at DDR520 @ 3-3-2-5-1t @ 2.8v. (Have not tried higher yet) Can't wait to get my Opteron 146 CABYE 0540 (arrives Monday) with the stronger memory controller. My SD3700 is a bit weak and requires too much voltage for my taste. The ram is definately not the problem, great job G.Skill :toast:

[J0hnB]

I've got a thread on these here:
http://i4memory.com/showthread.php?t=1625

It has links to other people's test reports as well as the beginnings of my results.

Mine went to 260 3-3-2-5 2.7V on my DFI NF3 250Gb
and 257 3-3-2-5 2.8V on my DFI NF3 Ultra-D

I'm still trying for better, since I haven't really tweaked any other timings yet.

[Silver Fox]

Got a pair of these myself, and I think I got some bad ones, cause once I go over 225 or so, it just starts giving me issues. I've tried all the settings that everyone else is using, and most of the time, I can't even pass the DMI check.

Running them near stock on a divider atm. I wish I can somehow get them to run around 250 or so...

[mucker]

The settings below, they are 100% stable for me. They may be relatively low speed, but are an excellent place to start from.

DFI nF4 Ultra-D using the orange slots, 623-3 official

These sticks are stable DDR458 @ 2.5-3-2-5 @ 2.7v but I am running them as follows for now (I need to get some work done;)):

These are the identical settings from Mr. GSkill USA, 1st thread.

[demenion]

I just got my set in.. copied the bios settings on the first page.. passed superpi 32mb @ 260 MHz frequency.

pretty impressed considering I only paid $190 shipped for this set :)

[massacre]

anybody who have a ZX kit can run to me a Sandra or Everest memorie bandwidth at 260 3.3.2.5 on ram nd 3100mhz on cpu ?

thanks

[Silver Fox]

I'm definitely gonna play with them more in the future. I honestly believe though that I won't be able to pass 230 or so, just from the rough outlook I've had. I'm on the 704 bigtoe bios btw. Running them at 2-3-2-5 208 on a divider atm.

[jhatfie]

Just got my 2GB set of the G.Skill ZX's today. I was previously running 2x512MB of the TwinMos Speed Premium UTT. I was not sure where to start with the G.Skill, so I popped in 2.5-3-2-8 timings leaving all the other timings the same and dropped the voltage to 2.7v and while still using my 166mhz memory divider, dropped my HTT from 300 to 250mhz to start off. Powered everything up and slowly brought it right back up to 300 doing superPi 1M real fast per increment to test briefly. Ran some more tests and amazingly, without changing a thing, it seems pretty damn stable at 245mhz. Played WOW and FEAR for a few hours and then ran some quick stability tests. Very pleased with them so far! I have not tried higher yet, but 2.7ghz is my cpu's sweet spot anyway.

How does this look?

[Metalkobra]

Which would be better for overclocking? the ZX or the HZ (pc5000) Wouldnt the HZ give more headroom and higher overclocks? Could someone possibly explain mem ratings to me (not like beginner stuff) but like is it really beneficial to get something higher than pc3200? If it is, I might go with the HZ instead...perhaps some kind of link showing its overclocking potential?

[Rattle]

I have the HZ's and they do about 270, I started with the ZX and they only did 223 or so for me, I figure for a few extra bux I get ddr500 at least and I'm happy with that.

Very pleased with the ddr500 kit, plus the spreaders are black to :p:

[Sky042]

you two are really unlucky :(
so how is those kits going on in here now

who else can not overclock this ram let me know, i am doing the stat now
I'm running this ram 218 2.5-3-2-5

[mucker]

Very happy with this result, 2.75 volts on the ram. Big woot for GSkill... :woot:

[Metalkobra]

so do you think the HZs can do 11x275 with some tweaking or 10x300?

[mustrum]

Just got my set in. 235 2.5 3.2.5 worked. 245 didn't boot anymore at 2.7 Volts.
I didn't do any tweaking yet so this is just a first test.
Currently running at 150 divider with the RAM at 221mhz stable while writing down the best settings for the RAM to try get higher.

If i can't get it to 245 for the 166 divider i stick to the 150 one and am happy.
If i can get above even better.

I will update as soon i know what i really can do.

So far the 150 divider seems no problem. It was my biggest fear that it wont work after reading comments in here.

Edit: The sticks are stable up to 267 3-3-2-5 !!!
I love these sticks. For the money they are just plain awesome!

[SaFrOuT]

show us please ur complete mem's timings setting and ur volt

[mustrum]

show us please ur complete mem's timings setting and ur volt
I used the ones from the G.Skill technician at page one. (Bios setup for DDR 540) Volts = 2.8v but the DFI is overvolting slighly i think. Should be 2.85 in reality.
Edit: CL3 seems important for my sticks. With CL 2.5 i can't get them to boot above 240mhz.
Currently i run em at 241 3-3-2-5 1T 2.7v. That's the 166 divider. That way i can run my CPU at max. 7.2k bandwith in Sandra is enough for my gaming.
This will be my 23/7 setting.

[geforce man]

just decided this morning b4 class to try out some slower timings to see if i got higher, and right now im @ 250 3-4-3-7-1t priming away, will try higher Mhz later, this zx kit is strange, 3-3-2-7-1t up to about 240,242, and now 250 @ higher timings, i wonder if it will go much higher than 250 @ these timings, 255 would be nice, ill try that later, just wanted to say that if your stuck, try a little slower timings, you may be surprised :)

lol
There's an explanation for that even!
I play the MMO Eve Online. It has 1 hour daily downtime and people use the term 23/7 often ingame for that reason.
I am so used to it that i use it outside the game allready. :D

Thanks for posting here btw. Your settings rock and helped me get lots of performance out of my G.Skills.

[ben805]

I was considering getting the ZX as my backup ram but after reading quite a few people RMA and return them because the sticks can't overclock past the rated speed....well.....I'm gonna have to look for something else, as I'm in fear of end up getting some of these left over junk that someone else's RMA'ed or returned, especially when newegg has the habit of putting those used item back in stock again. :stick: so the HZ can do about 260~270 @3-3-3?

[Phire]

Friend bought some 2gbzx the other day. I'm fiddling for a couple of days since he doesn't have his computer with him at the moment.

Currently memtesting 260mhz 3-3-2-5. This is 2.9v without +.2v. Highest i could get 1m passed was 268mhz. Havent done any 32m runs yet.

Tested with 702-1 and 623-3. Could pass 1m 1mhz higher going to 623-3. :woot:

Any idea how these would perform in a nf2 platform? Friend bought these in preparation for a64 but is currently running my old unlocked 2500+ and nf7-s v2.

Man, i'm using an old Voodoo3 2000 PCI 16MB here in my server, and a bloody monitor too, but am i seeing 2x1GB @ 300MHz 2.5-3-2-5 ??? I obviously think that's a CPU-Z bug, but that screenshot r00lz :D

Actually what's the real speed on those sticks? I think i'm getting some ZX after all...

[GSKILL TECH]

u should check A64 :)
CPUz just let u know i am runing at dual channel 1GB*2

[Xenom0rph]

I hear about people having problems with ZXs and having to RMA them. I hope not to have any problem, and also I hope that my sticks clock well ;)

i actually asked newegg about rma, until now is few kits (less than 10 compare to over 500 sold) got rma to them!

[SaFrOuT]

got 3 sticks of this kit few days ago here in Egypt

no time to test the three of them but here r our only results


mine now testing @ DDR490

mine is 100% stable @ DDR500 3-3-2-7 @ 2.6Vdimm
memtested it @ DDR500 3-3-2-7 @ 2.7 and was stable for more than 2.5hours
gone test it more in the next couple of days

another kit with my best friend
can do DDR496 @ 3-3-2-7 @ 2.7 and totaly stable
he told me that he is now testing them @ DDR520 @ 2T @ 3-3-3-7

the last kit is owned but not a mad o/cer like us so he only tried it @ DDR440 @ 2.5-3-2-7 @ 2.6 which is very stable with him since he got a 3500+ and he like 220x11

[Docmhz]

Wow only $185 at newegg now.

Very nice.

[mucker]

BUMP FOR $185 :woot

[SaFrOuT]

ok i guess i got the best kit ever

i am now @ DDR520 3-3-2-7 @ 2.6vdimm only using the most amazing bios every 704-2BTA and it is stable prime for 30min ( test 5 ) SuperPi 8m & 32mb

i recommand this bios for everyone using a DFI LanPArty NF4 based mobo

gonne try for more fsb or tighter timings but not now cause i need to sleep

[Dave_Sz]

Prime has a #5 test? I think you mean memtest, even then memtest doesn't test windows stability.

[Heretic]

For those looking to buy this ram, newegg has it right now for 185

[zenzog]

Bought a pair from newegg..

Hope it clocks good!

[SaFrOuT]

ya sorry i meant memtest

and for windows test i did tets using prime for 1 hour and before i did 2 runs of SuperPI 32mb and 1 run of 8mb

will test gaming stability but as soon as i get my 7800GT since i am working now on a pci v/c :S

[Docmhz]

Got some sticks coming to me. Hopefully will be good.

[Dave_Sz]

Priming for one hour is nothing. Remember, you test for stability to BE SAFE. First test prime to make sure it's stable, then after that run games. So run prime or stress prime for at least 8hrs, first small ffts, the larke ffts.

gonne try DDR540 now

[mucker]

For me:

DDR 400 @ 2.0-3-2-5-1T @ 2.6v
DDR 472 @ 2.5-3-2-5-1T @ 2.7v
DDR 510 @ 3.0-3-2-5-1T @ 2.7v
DDR 520 @ 3.0-3-2-5-1T @ 2.8v

All above settings are stable.

starts to get flakey around 270 HTT.

CAS 2.5 does not work at 250 HTT.

For the money, I am very happy with the performance of these sticks...get them while they are $185...

[SaFrOuT]

mucker

what si ur volt settings ?

[mucker]

I edited my last post to include voltages. I didn't bother with 2.6 volts but may try it some day. From past experiences, additional voltage really helps stability, and I'm not worried at all about a 0.1v increase.....

[dnottis]

I think the new PC3200 OCZ GX XTC uses the same chips as this...

I was just playing around with these again earlier today. Honestly, I don't know how you people get such phenomenal results. No matter what I try, if it's sitting at 230 (as a starting point), I get 10k+ errors on test 5. I'm pretty disappointed seeing as I was hoping to hit around 250 with these... :(

I've tried:

- changing volts from 2.6 to 2.9
- changing cas to 2.5 and 3
- tried all the timings that the users have posted, including GS tech's
- tried changing dram strength
- tried 3-3-3-8

Nothing works. Am I just unlucky? They do stock just fine, just not much more than that.

Same here, yes they are not guaranteed over the rating but you would believe these were "miracle" ram from the postings in this thread. Well it has had the desired effect of making these a sell-out anyway but I for one will be ordering some new stuff today.

[GSKILL TECH]

hey guys, pick a number between 0~99, i will pick a SN end with that number and test for DDR500 3-3-3-5 to see it works or not. just receive some shipment!

[MadMikeSS]

I'll pick a # and you send me the ones with that # at the end to test for you. :P

lucky 69..... :)

[MadMikeSS]

If they are good clockers, you can send them to me. Considering I ordered a set of HX sticks and Newegg screwed up my order and sent me DDR2 sticks instead. So while those are going back I expect a refund soon anyway... Been considering getting the ZX sticks instead but if people aren't seeing good clocks with them I don't want to gamble...

man i really can not do that! i only can test and ship to NewEgg! others.... i am sorry

sorry if the pics are too big. it is hard for me to edit with MS built in paint program..

Yeah dude, paint isn't good :s

BTW nice review, i hope this thread will help me choosing a 2GB kit for my rig.

Nice sticks if you picked them up on sale at the Egg over the weekend. Looks like they went through over 100 sets. Any idea if they be coming back into stock at those quantities and perhaps at the sale price again?

[zenzog]

So kits with sticks ending with 69 are good? :p:

Very impressive test. My sticks are that easy too, some of the most flexible I've ever owned...

[situman]

Are these sticks optimized for DFI NF4 boards?

[SaFrOuT]

using them here on DFI Nf4 LP Ultra-D with no problemz

[Dave_Sz]

Me too. Even though using value ram, which these are, on a DFI NF4 is a sin, these are working out pretty good.

Big difference between "cheap" ram and "value" ram. I would never put cheap ram on my DFI, but these G.Skill's are high quality and quite a "value" ;) Who labeled these "value" ram by the way? Linky please?

Awesome link, thanks :toast:

I think they deserve one more star though ;)

The HZ is 4 star 3-4-4-8 @ DDR500
My ZX is 2 star 3-3-2-5 @ DDR520

I like my 2 star just fine :woot:

[kemist]

The set i have seem to be pretty decent, however im currently using an epox 9nda3+ mobo. I was just wondering if it is possible that this board could be holding them back compared to what a dfi mobo could do?

[Tibu]

These sticks love cas 2.5. I think everyone should try it as you might be surprised. However I'm wondering if being to run cas 2.5 at say 250fsb is more dependant on the memory controller or possibly the stick themselves.

[mucker]

Could be controller specific, I couldn't do 2.5 with my Opteron at an acceptable frequency. I believe the cpu is strong, my ZX just weaker at 2.5.

I have confirmed that a San Diego core running 2750 MHz @ 2.5-3-3-8 @ DDR500 benches almost identically to a Venus core running 2850 MHz @ 3-3-2-5 @ DDR520. In my case, I can't run 2.5 on my GSkills at 275x(9/10) so there is no point in attempting it anymore. 2850 @ 3 will simply beat any 2.5 speed I am capable of running...

[p4spooky]

Received my 2GB ZX from Newegg yesterday. Running at DDR500 at 3-6-3-3 at 2.65V on Abit IC7-G with CPU 2.8C at 3.5.

:banana: These sticks are amazing.

[situman]

I'm waiting for the sale they had a week ago.

[ginfest]

Folks I had to come back to this thread to rescind my eartlier post and apologize for my frustration. I researched and changed some settings and have been testing at 240 1/1 for the past day. Ceratinly a great deal for the $$, glad that I waited on ordering some diff brand sticks!

No, your sticks love cas 2.5, not all of them.

[zenzog]

No, your sticks love cas 2.5, not all of them.

I agree. :(
Sadly, it boots at 245 @ cas2.5 & 2.8v, but BSOD's.
Seems to be stable at 243 @ cas2.5 & 2.8v though, which is probably what I'll be running 24/7 after I see how it goes later.
Not bad for value sticks! I'll be trying cas3 tonight. :)

These sticks could probably go higher if I had a DFI board, but I don't...

[Silver Fox]

Bah I hate you people, my sticks can't even come close to your results :(

I think I'll cry for a bit.. *sob sob*

I just got 2 sets of zx last night. Threw them in and without tweaking was able to get both sets, one set at a time, to do about 262-263. Will start tweaking to see just how far they will go.

i am happy too see most of you overclock this good.
wanna know that
is anyone here using 2GBZX with mobo other than DFI and MSI?
that just for my future info

[tomati]

Hi,

I have received my set of 2gb GBZX yesterday .

After some test , I pass memtest86+ v.1.65 ( with dfi nf4 expert) @ 250 3-3-2-5 (GS technician timing in first post) ~ 2.9v (2.92 under bios - 2.87 under smartguardian) standart test during 7h00 + , but when I run windows memtest (memtest under windows) during the first minute I got error ( I put 2 instances of 915 mo as the software seems not to be able of running more in one instance ), so my question is , could it be due to my memory controler ? I have tried all voltage from 2.6v to 2.9v but nothing help under windows , now trying 2.66v under memtest86+ , will see...) .

Don't know if I need to change the ram setting , if so , what way should I try to catch more stability under windows ?

Any input is welcome, thanks.

[deathman20]

Ah heres the right post I was trying to post in hehe.

Well I got some of these modules coming today. God love FedEx express saver and newegg, 2 day delivery always hehe. I was originally going to get these before everyone started saying the ballistix is the best. Ya best chance at failing in the board with rated speeds and voltages, let alone burning hot.

Looking forward to seeing what these can do when I get them, and thanks for the review, basically got me saying, where do I buy these hehe, like I should of done in the first place.

[GSKILL TECH]

are you using 915 mobo? i am not sure if the setting on 915 mobo should be same or not! let me know more~ thx

[qwerty!]

has anybody else done 255 at cas 2.5 like Tibu??? from what i've seen 265/270 is max oc at cas 3...

[tomati]

are you using 915 mobo? i am not sure if the setting on 915 mobo should be same or not! let me know more~ thx

Hi GS technician,

I suppose this repply is adressed to me.

No intel board , I'm using the new dfi nf4 expert , but when I start the windows memtest and try to test all my unused memory it pop up me a message where it advise me that as it can't run more than 915mo ;if I want to test all my memory ,I need to open a second instance for an other 915mo , may be I don't need to run this second instance ?

I'm talking about this memtest :

http://img523.imageshack.us/img523/1236/windowsmemtest3tk.png (http://imageshack.us)

Now the ram have succeed 2 full standart pass in memtest86+ ~ 3h00 @ 250 (3-3-2-5) with only 2.66v (bios setting).

Need I to increase the nf4 volt or ldt voltage ?

[GSKILL TECH]

yes i might need to using two memtest to test but make sure not over the "phyical memory not use value" on task manager. :)
also, if you only needs 2.66v to work it, that will be great! i used 2.9v only for 273FSB but i remember i used lower such as 2.7v to run around 250FSB :)
if any question let me know

Hi GS technician,

250 @ 2.66v successfully passed memtest86+ (5h00+ ,6 full pass) but I have had to bump it up to 2.7v for 3d05 .

3d05 succeed @ 255 too (2.73v) but failled @ 260 (even with 2.92v) , I probably hit the wall there.

I will continue my test ( now 255 under memtest86+ full standard test @ 2.73v , 13 full pass during 8h00 test safe) .

For my trouble with memtest in windows, I think you put your finger on, quick test doesn't show me same early errors as before but need deeper test ; I'm confident as 3d05 have succed at those timing now, so it's promising , right ?


So far so good , as I was expected for ~245mhz and I hit over 250.

GS technician thank you very much for your input.

[GAR]

Actually, now I'm finding that Everest reports better latency in cas2.5 than cas2 AND cas3. Less bandwidth (and that's what this forum is for!) but would it be better to use cas2.5 for the lower latency?

My sticks top out at 260 @ 3-3-3-6.. will try to loosen timings a little bit and see if it helps. :(

[dingetje]

i was thinking of getting these 2GBZX sticks or the 2GBHS
the price is almost the same...but which sticks do you guys think will be more likely to oc well, 2gbhs or 2gbzx?

This $190 ram is amazing.

I just passed SuperPi 32MB @ 270.1 MHz Frequency 3-3-2-5, 2.8V

27m 46s SuperPi 32mb

The HS is low-binned HZ, certainly no chance of good overclock.

Personally I still don't understand why people buy the ZX, not the HZ. The HZ is guaranteed 250 MHz.

While the people with excessive good luck manage to get ZX that does even better that is rare, the average ZX is between its spec and the HZ spec.

Don't know about all that stuff you've posted, but I do know that i bought 2 sets and they both do 262-263.

Be it cpu or memory, I've found the hardware that I've bought on the lower end most of the time clocks as good or better then the binned higher priced stuff.

[dingetje]

hmmm...difficult choice cuz the price difference is so small and i suck at making decisions
where i am (i am in taiwan of all places lol), i can get:
2gbhz for 254 us$
2gbhs for 215 us$
2gbzx for 221 us$
should i gamble and try zx (or even hs) or go for the garantueed hz for some more money, what would u guys go for at these prices?

[Dave_Sz]

Oooh, I could sell you my ZX for $210 shipped. It does 260mhz but I'm not sure if I wanna get rid of it already.

[dogsx2]

Just test both sets of zx and picked out to strongest 2. Here's my results:

http://img403.imageshack.us/img403/8013/268zx1hc.th.jpg (http://img403.imageshack.us/my.php?image=268zx1hc.jpg)

Just a little better then random but not much.

[aicjofs]

has anybody else done 255 at cas 2.5 like Tibu??? from what i've seen 265/270 is max oc at cas 3...

I have tried on a few different ocassions, but 249 seems to be the limit for 2.5CAS on this set I have. ~268 for CAS 3. I need 255, so CAS 2.5 was out of the question for me.

Personally I still don't understand why people buy the ZX, not the HZ. The HZ is guaranteed 250 MHz.

I know alot of the old time overclockers like myself still have the mentality of getting the cheapest parts and gettting them to rival the best parts. In the beginning(for me) the cheapest CPU that could be bought was probably $250 and up, where a CPU with less then 30Mhz more was twice that much. Old habits die hard. Then again you will never find a post of mine whining about not getting the overclock I wanted, or at least not blaming it on the manufacture.

You seem to only be talking about one angle. It's a matter of perspective. I make almost 6 figures and I can't understand why anyone would buy an FX/EE or a CPU much over $350, I have the money to do it, but it seems a waste. Blah, blah, it's XS. But honestly it's not AS impressive to me to see the guy with the $1000 CPU, quintriple cascade, liquid hydrogen, absolute zero running system. Sure it's fun to read about, that's why I am here, but the avg enthusiast can't afford that. I am much more impressed when the community comes together and we find the right combination of parts for a $1000 system to beat or stay on par with a $3000 system. Obviously this Gskill example is only $30 but it's the principal. Some people can't dig up the $300 for Ballistix, or the $250 for the HZ, so here they are doing their XtremeSystem thing with these Gskills(and these RAM IMO are quite the deal if you have a good set). If they get lucky they saved enough to pay their electricity bill.

I feel empathy for those that don't get the sticks to do what they hoped for, but I don't feel sorry for them. Which I think is what is getting to you, but for you to ask why people do it???....perspective Martin, perspective.

[MadMikeSS]

Personally I still don't understand why people buy the ZX, not the HZ. The HZ is guaranteed 250 MHz.

The HZ is rated 3-4-4-8 at DDR500 also, I see people on here listing better timings with thier ZX at DDR500. So why not go with the better timings at lower price? Besides, newegg lists the HS for $229 while the ZX is $212. Not much difference in price but the potential for better timings at a lower price.

[tomati]

Hi,

This is really strange , I'm confuse here.

I succeed

1°) memtest86+ @ 255 3/3/2/5/1T ~ 2.73v ,

2°) the long memory test (~3h00) of S&M (250 ~2.7v),

3°) all 3d0x series (250 ~2.73v),

4°) playing ~2h00 with need for speed - Most Wanted (250 @ 2.7v)

I have tried 2 A64 3200+ E3 and both gave me the same result ,

I've tried with divider 150/166/183 and in 1/1 .

I still can't pass more than a 4M Spi ? (tried @ 250) 8M failled, I have played with the MAL and the RPT but have not yet found the good setting , I'm sure it must be a ram setting but what way to find it , I'm not an expert with all these ram settings.

Yesterday , after setting the ram in bios @ 3/3/2/5/1t (all the rest @ auto) I have passed 3d05 and 03 @ 250 with only 2.62v but not Spi 8M ??? (I had need before 2.7v to pass 3d05, so strange).

Somebody know if there is a new bios for the Expert serie of DFI Sli-dr that's supposed to be better with the new 2gb ram kit ?


PS : :woot:, I found the origine of my trouble : crapy NVIDIA IDE drivers !!!! :slapass:



I have discovered it when my dvd rom didn't refresh after loading a new cd , after coming back to the microsoft ide driver all have been working fine, I have completed an 8M Spi and 32M right now @ 250 with only 2.61v(smartguardian report).

At all of you who are running with NF4 , are you using the NVIDIA IDE driver ?

Yes , now I'm using the microsoft ide driver and all is fine ( 260 in the nose for 32M Spi, max screen @ 265 but no bench)

I have first trying to install windows (sp1 full fix updated) with the 6.70 but get error so choose the one that are on my dfi cd driver ,the 6.66 ; as I come from kt600 , I didn't know that the Nvidia ide driver can cause some trouble ( cd-rw and dvd-rw not recognized or impossible to burn) , so I have allowed to install them when pop up ask it to me, my bad.

[situman]

are these Brainpower PCBs? The overclock seems to be very inconsistent to be Brainpower PCBs.

[GSKILL TECH]

yep it is BP PCBs

[Guido]

could someone help me decide what memory i should buy?
i've got an asus a8n-e and an amd 3200+
it overclocks stable at 2600mhz, haven't tested intensively higher but 2500mhz would suffice.
it's a very silent air cooled sys, with 2x 120mm and an arctic freezer 64. with qfan on it only goes 1200rpm instead of 2200rpm.
to reach 2600mhz i had to raise vcore to 1.50, stressed its 46C, 2500mhz stressed just 43-44.

I'm undecided about the next 2...

G.Skill 2GBZX DDR400 2-3-2-5
could maybe reach: DDR 500 @ 3.0-3-2-5-1T @ 2.7v
cpu 250 x 10 = 2500mhz

G.Skill 2GBHZ DDR500 3-4-4-8
could maybe reach DDR560 @ 3-4-4-8
cpu 280 x 9 = 2520mhz

What would give the best performance?
Right now I've got corsair 3500LL pro but won't go higher than 240mhz 2.5-3-3-8 on 1t :slapass:
On 2t it will reach 260mhz :cool:
Is that mem related or memory controller?

[sn_85]

i'd go for the HZ. you know you'll at least get 250. my ZX dont go very far

[deathman20]

My HZ so far on default 2.6V went to 260 tested.

[eviLRuLeZ]

hello
are these chips pre-tested ?

[greendestiny]

How did you guys get the 2GBZX to do 260MHz 1:1 with 3-3-2-5 ???

I got it to do 260MHz, 1:1 3-3-2-5 with FSB of 260MH, no dividers, and followed GS.Technician's bios settings...it boots to windows, but 3DMark05 will hang and games like Need for Speed Most Wanted will also hang randomly...about a minute into the game..

i have to run a 9/10 divider 180MHz to make the RAM do 236MHz FSB in order to run...

[ginfest]

After a week at 240 1/01 3-3-2-7 I just kicked mine up to 250 1/01 and had to go to 3-3-3-7 timings. My eventual goal is to get my Opty 170 to 2600 hopefully the ZX will still function at 1/01
I'm running the VDimm at 2.7

Just like the new Mushkin Redlines (2GB) and the OCZ PLatinum EB (2GB), I don't think these sticks are very 3D stable (they probably all use CE-6).

My redlines passes superPi 32M, memtest, OCCT without a problem at 3-3-2-8 @265, but will only run 3Dmark01 and other various games at 3-3-2-8 @255 without crashing.

[greendestiny]

yeah i think its Windows...and Memtest stable...but it sure as hell ain't 3D stable like you said...3dmark05 and games will hang....

funny how RAM can do that! run memtest and boot windows fine, but crash in games...

[uOpt]

Heat from the graphics card would be one explanation.

Does it prime allright for 36 hours?

[Heretic]

Through experience, 3D stable and Prime/memtest/SPi stable are two very different things. I primed my sticks @ 260 3-3-2-5 for ~36 hours (I forget the exact number, it was a few days ago), but I'd crash eventually in CS:S and NFS:MW. I'll be playing some other games to see if it's just those two (for some reason), but I seriously doubt it. I'll also try giving it more volts.

[Guido]

Thnx for the advice guys, I think I'll play save and order de HZ for an extra 30 euros

[greendestiny]

yes, its prime and mem test stable of course!

and the thing is, its NOT the CPU or anything else....because once I go back into bios and down chip that sucker to 236MHz ..it runs like a dream in games and 3dmark05 again....

[GSKILL TECH]

hmmmm how many ppl experience about 32M memtest stable but no game?

[101]

I've have 4 gigs of the new infineon chips, one pair of gskill ZX the other redline 4k, and have seen prime, memtest, and OCCT stable settings fail very quickly in games on a DFI expert (shipping BIOS). Even with considerable tweaking the only way to get it stable was to drop the frequency.

[top game 22]

my gskill zx is is game stable and prime +super pi.. @500mhz on div. 2.8volts.
how come my gskill says jade star tec..

does all 4 sticks fail on game?

[ginfest]

My timings aren't as good as some here but running 250 1/01 3-3-3-7 2.7 vdimm, my Opteron is at 2500, 1.35(*104%) vcore and has run P95 x2 for 8 hours, Super Pi x2 32M and I've done a good 6 hours straight gaming, FEAR, Q4, and EQ2, no crashes at all.
Needless to say that I am quite pleased with my first AMD build, this setup blows away my old P4
I hope to eventually get 2600 out of the Opty, and hope the GSkill will follow ;-)

[Manol]

hmmmm how many ppl experience about 32M memtest stable but no game?

Me, im also one that experiences this.

AT 250mhz and 255mhz NFS:MW and 3dmark will randomly lock up and freeze and for some reason if they dont freeze my 3dmark goes down a long way and the FPS are terrible, but memtest, superpi etc etc are completely stable. But if i move it down to 247 stock timings but CAS3. Its perfectly fine and stable in everything games and stress testing programs.

G.Skill Tech can you provide any light on this issue?

i have no idea about this. i don't have good vga card to play game :(

[Manol]

i have no idea about this. i don't have good vga card to play game :(

Its just that they are very odd, symptoms to happen if the RAM was not stable. Is it your settings perhaps? Or is it just the RAM is not stable at that speed?

Also could it be the memory controller on the CPU not being able to handle sucha high speed?

Thanks
Manol

[Middleeye]

im stuck @ 3-3-3-7 250MHz 2.8V too, perhaps 2.7V would work too haven't tested yet.
I can't get any timings tighter or even memtest errors out...

anywayz, I'm quite happy with the overclock, these are better timings than the HX @ 3-4-4-8 250MHz

have run dual torture large FTT + mem torture for over 5 hours, so I consider it stable... gaming and 3d marks all go perfect...

[Middleeye]

currently running at sig specs... quite happy :)

[Squire]

i have no idea about this. i don't have good vga card to play game :(

It's just a characteristic of this IC...

[GSKILL TECH]

i am going to ask G.Skill about playing games during my office hour since it is some test to see the memory is stable or not. or add into RMA process. Man i can only do 1 RMA per day..... :)

back to topic, if all kinds test passed but why games won't.... becasue more transfer between CPU and RAM, or why? there must be something, let discover this together

[uOpt]

back to topic, if all kinds test passed but why games won't.... becasue more transfer between CPU and RAM, or why? there must be something, let discover this together

Apart from the obvious possible cause of more heat (due to graphics cards active), there are two more possible reasons:


WIth tight timings it might make a difference whether the CPU reads/write data for its own consumption or just for transfer via AGP or PCIe. Obviously, the overall timing of these transfers is fundamentally different.
Prime95 and SuperPi only test a small part of the RAM. Memtest86 tests all RAM but doesn't load the CPU. It is possible that CE-6 sticks tend to have larger areas where they go higher with loaded CPU, but other areas, not tested by Prime, don't go as high.


Theory number two could be verified by using Prime95 under different OSes. There are versions running on Linux and FreeBSD. These should end up loading different areas.

I would say the dropping of 3dmark scores as they near instability is the exact same behavior I am seeing, very similar to a marginal GPU OC. Possibly a result of indiviual chips on the stick dropping off. The mushkin however runs siginificantly faster and has a very clear wall where all the chips max out together. I would guess this is indicitive of more stringent testing and binning at the component level for these higher priced sticks.

However, as a generalization, both sets seem to fail in 3D before anything else. Quake 4 in ultra quality, BF2, FEAR, set to go way over the 1 GB boundry seem to be good tests. I've seen a marginal speed low score 3dmark05 run fail instantly in Q4 ultra quality, and run fine in high quality.

Perhaps it's a flaw in the module PCB layout that is exploited in particular with these infineon chips and very large processes.

I think 2nd one is more reasonable, :)
for prime95/sp2004 if using blend which loaded memory and test both CPU
and memory, well that test help?

actually for windows memtest, both CPU and memory load i believe. i remember if CPU is not stable then memtest fail either.

[uOpt]

Unfortunately there seems to be no way to make prime95 work over all of physical RAM.

Even if you changed prime95's source code, the OS will prevent you from nailing down to certain locations in physical memory because userlevel programs only have virtual memory. And even if you forced it to do that, then you still face areas where physical memory is permanently allocated to non-movable data such as OS-internal data - and sections that are used for intermediate storage of data exchanged with the video card.

However, if you prime95 under Windoze, Linux and FreeBSD you are almost guaranteed to test at least three different sections.

Best would be to make a self-booting prime95 CD based on MS-DOS. Then you only have physical memory and you can do each iteration of the prime95 tests on a different area.

It might be possible to re-write prime95 as a Linux or FreeBSD kernel module and do a self-booting CD with that. That way it could access physical memory, too, but you wouldn't have the hassle of dealing with MS-DOS' braindead memory allocation.

thx, i learn a lot today!

but if we open more prim95/sp2004, two blend or custom large test with custom phyical memory size, will that possible to run most the memory. but just like you said, heap, stack, and OS area will not be touch. it is hard to do but if 3 OS prime95 testing... well..

but i am just startig learning Linux and FreeBSD now, noob lol. but prime95 under linux and xBSD will testing different area? i will try it later, since install linux is not like windows, xBSD takes even more time for me... :)

[bachus_anonym]

With 2GB physical memory, P95 or SP2004 and 32-bit Windows you can allocate and test up to:

(a) ~1.80GB under Server2003,
(b) ~1.50GB under Windows XP (P95 v24.6, but no SP2004 based on P95 v23.8)

But that is virtual memory. You have no way to know what physical memory the OS chooses to back up the pages that the userland program uses.

[Manol]

So in the end? Whats the deal with the chips being everything else stable but not 3D anything stable?

Is it a case of bad luck, something we can change? Or can we get the chips replaced?

Thanks

[dogsx2]

I was swiching memory around and forgot what I had in. I set it to 2.5-3-2 and had to back down the MHz to 240. That is the highest my best set of zx will do at 2.5. Not worth it though. 3-3-2@268 beats the pants off of 2.5-3-2@240.:D

[Yegg]

I bought the 2GBZX kit for my new gaming rig, did I make a big mistake? Or is it possible to clock my Opteron 165 to a reasonable speed with this kit, and still have stability in games?

I started shaking when I read about the instability in 3D/games :(.

[uOpt]

Running closer to spec with a divider should be just fine and won't hurt performance noticably.

[swiharta]

I can't even boot into Windows running this RAM at 200mhz 1:1 at 2-3-2, it will boot ok at 3-4-4 though, I'm feeling seriously ripped off to say the least!

I have Patriot TCCD that does >267mhz at 2.5-3-3

My system is Epox 9nda3+, Antec Neopower 480 PSU, Opteron 165

I'm putting in for an RMA request. Hey GS Tech, will they just send my RAM back to me if it works at stock on their test computer?

From the looks of recent results on this forum, including mine, I think the RAM in these chips has been rediculously unpredictable, where early performance was awesome, now people are barely running it over stock, probably they switched from using different chips but the labels on all the products are the same.

But please note that the Mushkin set with the same chips has precisely the same problem. Early ones were doing well, later ones don't.

Can't say for OCZ because they were "lucky" not to get any chips and the EB kit is sold out everywhere for a long time now. But they seem to have missed a bad shipment of these chips.

Or OCZ received a shipment and refused the chips after testing :)

[Squire]

lol, if OCZ really did that, much propz to them hehe.

Perhaps that is why OCZ platinum EB CE-6 are so rare and the other modules containing CE-6's are so plentiful?

[GSKILL TECH]

actually, how many ppl in here has the 3D unstable problem? i had ask around ppl who has 2GBZX and non of them had found this problem. however, they don't really overclock to all the way max, some of them not even overclock lol. over all 2GBZX is a great product to me. if you guys experience 3D unstable, try to lower ZX's speed. let me know i am always here.

No, HZ and HS are UCCC.

The ZX is probably the Infineon.

Nobody ever figured out what the HX is, except we know the chips are expensive. COuld be Hynix. The same chips are probably on the Value NG set, although I get the value kit gets any leftover chip once in a while.

What we need is a photo database of the chip's edges.

yes i am also the one that can vouch that a 3-3-2-5 timings and 260MHz 1:1 DRAM FSB.... the PHU-2GBZX 2x1gb ram...in dual channel.... will prime stable and also memtest fully stable...
the system will only boot with a CL3 timing @ 1:1 260MHz FSB...

but the minute you run a game like nfsmw, or 3dmark05, it will crash and hang on you....actually it will hang on you.. =)
but like i said...memtest is good/prime is good....just games no good......

windows is also good =) i can surf the net/chat/do documents in 260Mhz dram fsb...at 1:1.....



now if i run divider it'll be fine...9/10 divider gives me 236MHz FSB....with 2.5-3-2-5....(now i can reduce CL to 2.5...2.0CL won't boot...but 2.5 lets me boot..with 236MHz Dram FSB)

but no games at 1:1 260Mhz FSB.....

even though your first page did mention it CAN do DDR520 @ 1:1... that is probably not going to be game stable at all.....

Edit: I just notice that your using a 3800. I had a 3800 and the memory controller was no where as good as an opty. That may be the difference.

[MadMikeSS]

Just got my ZX kit in today. Had to let them warm up to room temp for a bit before I could install them cuz Fedex lets them sit in the cold. :) But this is what I"m doing so far, haven't tweaked anything yet. Just set for the same speed as my last set that was in but changed some timings, set manually 2.5 3-3-6 with divider for 241 speed on the ram. All the rest is auto. If anyone has some suggestions to set any of the timings please post me an A64Tweaker screen or a list of your settings.

Hi guys, today i recived this memories (2x1gb gskill zx) .

I have a lot of problems, i can´t put the mems over 200fsb, with any vdimm or any timmings/alphas.

One thing so strange. I run windows at 220x11 2.5-3-3-5 2.6v, superpi 1mb/8mb/32mb don´t run over 1 sec, always crash. Then , 2 minutes ago, i run one superpi 32 mb and do all the test stable, then i run 1mb superpi and don´t run more than 1 sec again...... Is so strange.

Some pictures.

[MadMikeSS]

You're not giving your cpu much voltage, try increasing vcore a little and see if that makes a difference. The higher density sticks are a little tougher on the mem controller in the A64. See if that helps out a little.

[ReviTK]

Is not a problem of vcore, my sandy 3700 do 2600mhz at default vcore. I´m desesperated T_T

DFI NF4 SLI DR
2GB GSKILL ZX

and the standard rest.....

Well my problem.... I installed this memory yesterday running everything stock at 2.6Vdimm. Now I copied some information...well big files...from a cd, and my system will just reset and start up again, only to do the same thing when I try to copy the same stuff. Replaced the memory with my old Mushkin Special's and no problem. I installed the ZX again and run SuperPI 32M and it bombs out after about 1 to 5 seconds....... I run the memtest in the BIOS for about 6 Hours with no problem, and all the settings for the memory in the BIOS was an auto.

Any ideas what to do.... Oh the bios is the 623-3 bios for the mobo....

Ok but your memory controller is on the CPU and now with 2GB of memory, which is difficult on the CPU - vcore would be the first thing I would try. Try to loosen the memory timings a bit - they may not be able to run 2-3-2-5 @ 220. Try 2.5-3-6-3 for now...

Thx, i try 1.5v and the problems persists.

I remember i had same problems with my last OCZ vx .

[ReviTK]

Pleas help me!!!

Note: i´m using bios 702-1.

New image, 210 2.5-3-3-5 2.6v Not stable..., so strange.
I can run windows at 255 fsb (not stable), but can´t get stable only 210??, something wront here i think.

Note2: At more vdimm, more inestability.

hi,

i'm in the market for a set of 2x1gb for my system and these seem interesting;

i would like to get them to around 255 at cas 3 (2.5 would be even better) but my real question is : have these been tested with an A8N-sli deluxe ? Too bad I (re)discovered these forums a bit late as it is clear i should've gone with the dfi-flavoured boards :).

any idea where you can get them in belgium-holland-germany for a reasonable price ?

rest of system: 3700+ SD currently running @ 2805 mhz (11x255) but my corsair 3200LL seems to be holding me back (using a 166 divider) so running mem at or around 400ddr 2-2-2-5 :nono: ; won't go much higher than that, even on looser timings

thanks

[ReviTK]

Nobody have any idea??? :(

[biohead]

ReviTK why are ECC and 2T enabled?

[ReviTK]

2t is only in these screens.

Now is "stable" at 240 2.5-3-""3""-5 2.6-->this 3 is important, at 2 always reboot.

But i can´t go over 240, i prove the some setting at 2.7v & 2.8 and can´t do over 240. Then i prove 3-3-3-5 2.6/2.7v with some problem.

have you tested one bank of ram for time?

[fatty]

I got mine they sit happy at 250 5,2,3,2.5 at 2.8v I havent tried lowering the voltage yet :)

[dingetje]

Yes, Samsung UCCC?

F1-3200USU2-2GBHS = Samsung UCCC
F1-4000USU2-2GBHZ = Samsung UCCC

The 9th character of the part number would be denoting the chip manufacturer.

so if the 2gbhs has samsung uccc like the 2gbhz would that mean that the hs sticks will not need extra voltage for oc like the hz is known for? the main reason i am going for the hz and not the zx is that the hz is known for its good results at stock voltage.

now should i go for the hs or hz? will hs also perform great without cranking up vdimm like the hz does? hs are cheaper than the hz and the hs 2.5 stocktiming seems better, thats why i ask :banana:

dont know your location but hz is same price as hs at newegg. both are going for $199.

[dingetje]

thanks for the tip sn_85 , but sadly im in taiwan ...yeah where the gskill is coming from.... and i have to pay 254$ for the 2gbhz and 220$ for the 2gbhs....kinda sickening to hear you guys over in the us have a way better bargain ;)

g.s.technician can't you phone home to tell your boss to lower the prices in guang hua? :p

[bladebel]

i'll have a set of these tomorrow, hopefully they will work fine on my asus A8N-sli deluxe and will do 255 (@ whatever timings) ...

i'll keep you guys posted but any ideas on what ram-settings i should start with ? (bios or a64-tweaker)

[Yegg]

I also need some help with my 2GB ZX-kit.

I can't get them to boot at higher speeds than this, running on 2.8v:
http://img454.imageshack.us/img454/7098/memory2bk.png

I have tried different timings, voltages etc, but without any luck.

These are my A64Tweaker settings (if I press the "Set"-button in A64Tweaker, the system hangs):
http://img499.imageshack.us/img499/5492/a64tweaker1at.png

Anyone who could point me in the right direction? I'm a newbie to overclocking memory, never owned any RAM that didn't have the word "value" in it.

Thanks in advance, Yegg.

[bachus_anonym]

@Yegg,

If I were you I would first start without ANY divider, just to see how far you can go. Also, you should use different settings in BIOS as it looks like you literally have EVERYTHING in there set to AUTO - not always good ;)
Take a look at my screens here (http://www.xtremesystems.org/forums/showpost.php?p=1119913&postcount=2) or those posted by G.S Technician in this very thread we're in. Then we can see what can be done next :)

I set it to auto recently, as I got pissed off since it wouldn't boot. I'll check tomorrow how high I can go tomorrow, gotta get up early, last day of school :woot:!

[ReviTK]

Yes, the some result than two modules at time.

[GSKILL TECH]

you might want to try my seting on the 1st page, of cuz you need to just a bit some of the timing. some of your setting are way off then mine. let me know

this was 1:1 in the bios but what does cpuz mean fsb/dram cpu/14

[krampak]

I've just got those memories. I'm getting errors at 210Mhz Cas 3-3-2 2.7V :confused:
Seems as bad as the Yegg KIT. This is on a DFI SLIDR Expert with 704BT bios and orange slots.
It just run at 200 2-3-2 and nothing more.

http://img287.imageshack.us/img287/6324/problem8gg.th.jpg (http://img287.imageshack.us/my.php?image=problem8gg.jpg)

Will try with exact same timings in the 1st post now... but I thing that this should be runing fine at those timings...

Which value is 100Mhz 1.95us in bios?

[gundamit]

This is on a DFI SLIDR Expert with 704BT bios and orange slots. :confused:

[fatty]

I am running the dfi sli dr non expert board with the 623-3 I think bios my memory does 260 fsb @ 5,2,3,3 I think thats all shes got but it will do 255 @ 5,2,3,2.5 I am running 2.8v I just haven't turned it down it passes memtes and super pi 32 meg in 24 mins

[krampak]

gundamit ?

I just got that bios from: http://lejabeach.com/DFI/dfinf4expert/

Thats pretty strange, I've just passed it fine at 245Mhz SAME timings (3-3-2 2.68V)... weird :stick: Problem solved?

Not! After every reboot it becomes unstable again at 205-210Mhz :stick:

[gundamit]

gundamit ? The name of the file looks like its a BigToe bios from July for the original DFI NF4. Your board is running, (albeit somewhat unstable) so it must be an Expert bios. Odd choice for the name though.

[fatty]

Max stable at these settings

http://gallery.greatestjournal.com/albums/up5/462/929462/dt2.jpg

[krampak]

Seems i've found an stable configuration. 250Mhz 3-3-3 at 2.7V, all timings set in bios (exact as the first post).

Edit: It's finishing OCCT Test at 255Mhz Cas 3-3-3 1T 2.70V

[kakaroto]

Does Trp at 2 not work? What are your full settings with A64 tweaker?

[krampak]

With Trp at 2 can't boot over 235-240Mhz.

Those are my current timings at 250Mhz 2.73V:

Couldn't try anything yesterday, caught the "winter vomiting disease", I think that's what it's called.

Today I got the memory to this at 2.8v (not sure if it's stable or not):

these are the only things I have set in the BIOS, I'm doing 2.5 3-2-5 2.7v at 241 right. I've had them up to 250 3-3-2-5 already also same voltage. Every other settings goes to Auto.

[xxxAgentxxx]

Could I get a tech to PM me on what to look for under the heatspreaders? I'll do a check before I say start crying on here about receiving a bunk set of these from newegg. I started at 250 with the timings displayed on the initial page (ultra d, venice 3200 stable up over 2.6ghz). I couldn't get into windows. I had various plans of spending hours upon hours of tweaking to see the highest I could get them to go and at various voltages ect... but first I had to get into windows...
So... I lowered fsb in 5mhz increments to get into windows... at 215 I finally got in, crashed almost instantly at desktop... at 210 I got into the desktop, stable for 30 seconds this round... then crashed, not even under load. (please remember that was at 3-3-2-5)At this point I decided to test my pair for its rated timings / got into windows, crash under load.

Regards,
agent

[bladebel]

i have installed mine yesterday in a A8N-sli deluxe from asus, at stock settings everything ok, prime stable at loose timings about 240 1:1 but have to check further but i do have two questions:

1) whenever i change the cas setting in windows (A64-tweaker), the system hangs; any ideas to why ?
2) A64-tweaker doesn't seem to properly remember my settings when i save them , whenever i load them afterwards 2-3 things are different again (e.g. tref & mem clock 3 disabled); i've tried changing this in the file itself with notepad which worked for mem clock 3 but not for tref for some reason ?

then just one general question because the settings in this thread (tried all of them) don't seem to work with my setup; what are the settings i should definetly loosen first to get high(er) clocks ?

thanks
