are these Brainpower PCBs? The overclock seems to be very inconsistent to be Brainpower PCBs.
yep it is BP PCBs
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?
i'd go for the HZ. you know you'll at least get 250. my ZX dont go very far
My HZ so far on default 2.6V went to 260 tested.
hello
are these chips pre-tested ?
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...
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).Quote:

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...
Heat from the graphics card would be one explanation.Quote:

Through experience, 3D stable and Prime/memtest/SPi stable are two very different things.

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.
Thnx for the advice guys, I think I'll play save and order de HZ for an extra 30 euros
yes, its prime and mem test stable of course!Quote:

hmmmm how many ppl experience about 32M memtest stable but no game?
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.
my gskill zx is is game stable and prime +super pi.. @500mhz on div. 2.8volts.
how come my gskill says jade star tec..
i think somehow they did the spd code wrong!Quote:

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 ;-)
Me, im also one that experiences this.Quote:

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 :(Quote:

Manol
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...
currently running at sig specs... quite happy :)
It's just a characteristic of this IC...Quote:

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:Quote:

- 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.Quote:

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, :)Quote:

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

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

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.Quote:

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
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 :(.
Running closer to spec with a divider should be just fine and won't hurt performance noticably.
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.
Did you try a full CMOS reset?Quote:

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

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.
It seems the chip type is encoded into the part number?
F1-3200PHU2-2GBZX = Hynix
F1-3200BIU2-2GBHX = Infineon
F1-3200USU2-2GBHS = Samsung
No, HZ and HS are UCCC.Quote:

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, Samsung UCCC?Quote:

The 9th character of the part number would be denoting the chip manufacturer.
But we are pretty sure that the ZX is G.Skill's Infineon set.Quote:

We need that photo database :fact: :fact: :fact:
just let you know ZX is not using Hynix
PH means value ram :)
G.Skill Technician...
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.....
i got no problems with the RAM...i paid a decent price for it on thanksgiving day at newegg..they had a nice special price..couldn't resist...
in case you wonder, here's the complete full system specs:
DFI LanParty uT ULtra-D Motherboard (BIOS 6/23/2005)

by the way...does anyone kno what voltage these 2GBZX's can handle?? 2.9V ?? 3.0V ?? my DFI motherboard allows me to take this ram to bizarre voltages...i'm talking higher than +3V...altho i don't know if i want to do that....Quote:

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.
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.

THX.
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.
Is not a problem of vcore, my sandy 3700 do 2600mhz at default vcore. I´m desesperated T_T
Okay system specs:
4000+ A64 SD
DFI NF4 SLI DR
2GB GSKILL ZX
7800GTX
120GB WD SATA
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....

Thank´s all.
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
Nobody have any idea??? :(
ReviTK why are ECC and 2T enabled?
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?Quote:

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.Quote:

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)
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:

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.
@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 or those posted by G.S Technician in this very thread we're in. Then we can see what can be done next :)
Thanks for your reply :)Quote:

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

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

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
Seems like my sticks are crap then :(. Mine won't even boot at 220 at 3-3-2-5 with all other settings on Auto.Quote:

Will the sticks do 200fsb @ 2,3,2,5 ??
They will, but anything higher won't boot.Quote:

Are the current kits working out for buyers or not
Well, I have confirmed this is the right stuff, atleast by overclock... This set I have simply won't run stable at trp 2. I can get the ram bench stable @ 3-3-3-5 242 at maximum before the crashing occurs again, and ofcoarse anything less than that will load / run windows just fine.
I'm a little (un-exagerating) disappointed in this set, I purchased a pair for my brother and tested them in this same system, straight out the box they did 250 3-3-2-5 without so much as a hicup. I liked that, and decided to go ahead and pick up a set for myself. It just figures I get stuck with the dud set. I would keep this set had it run 250 3-3-3-5 with stability, but it wont even get to the windows loading screen at that speed.
*sigh*
Mine are finally stable at 251 3-3-3-5 2.68V.
Which is the maxium safe voltage for this type of memory?
It's officially rated for 2.6-2.75v. So you are still safely within rated voltage. I've had mine up to 250 3-3-2-5 2.7v.
the recent 2GBZX is not stable on Overclock, i recommend to buy 2GBHZ for now. but for DDR400 users, 2-3-2-5 2gbzx still is the best choice :) right?
2.65v is very good :)
and guy,if your 2gbzx is not oc well, post some pictures and someone will love to help, thx :)
So would these be the sticks to get if you are willing to have slightly less cpu HT but beter timings or would that ne the HZ
I do not play games so I do not care about 3dmark scores, I care about performance because I use 3d programs which requires good I/O bandwidth which I think CAS timings mater
