Official GSkill 1gb-GH pc3200 2-2-2-5 info and results

The 1 gig kit of GH is in stock at digi4me for $210.

http://store.yahoo.com/digi4me/gs1gb5ddrduc.html

OPB are you using auto on tref?

I use eother 166, 1.95us or 100, 1.95us

**btw, digi4me's price is too high, I will tell them get that below 200. :)

Good to hear GH is getting available in USA, Europe still is waiting.. hehe

Very nice results OPB. I only get 265MHz 2-2-2-5 maxed stable. 3.5v :p:

any shops ships internationally?

OPB, you're awesome. :woot:

nvm already asked digi4me.. they ship international

when are we seeing it under 200? :P

can i get link to purchase these from newegg or some other place?

http://store.yahoo.com/digi4me/gs1gb5ddrduc.html

here Calcal

think i will pick some up, just hope newegg starts carrying them

hrmm 210, ill have to think about it i thoguht it was gonna be like 110 like the other UTT's

They're for sale at Newegg for $197.85

http://www.newegg.com/app/viewProduc...factory=BROWSE

I already bought a set so I think there are only 4 sets left :bananal:.

yep, only 4 kits in stock... be quick if you want them, nice price for some good ram.

I am gonna have someone in US order these modules for me. I just got one question: is this pair of memory using Winbond BH-5 chips?

I also saw some new series of G-Skill GBLA which is @ 300 bucks. Which is better between GBLA and GBGH?

any chance of running these at 270-275 stable on a dfi?

i don't know, most bh-5 seem to hit a ceiling at ~260MHz (prime stable)

I think 266 can do prime 95 pretty stable @3.63v:)

would you run a dfi nf4 with a FX55 24/7 at 3.63v?

no , I won't do it for 24/7
but I tried 3.2v DDR500 for 24/7 :D

OPB, do you know when the PC4000 1GBGH kits are going to be available? They're really the ones I want. :toast:

So, (i know this is an ambigous question), what could i expect on this ram, with my modded (3.3v straight to DIMM) Neo2 Plat? Any issues i should be aware of before i order a set?

whats the max voltage that you would run opb 24/7 with a fan blowing over mosfets and ram?

3.3 will be good enough
BTW, now the price will be around 160 for GH 1g kit.:D

Now 4 kits in stock at NewEgg for $180.

Hmm, that ram looks tempting :)

The 4000GH would be even better...

OPB? :stick: :p:

up to what voltage are they still warrantied?

So I guess that means there probably won't be a GH PC4000?

Don't get me wrong, the current GH looks very, very attractive for the price. But the chance that maybe 1 in 10 sticks won't do 250mhz 2-2-2 is still too high for me. I already have way too many sticks of various UTT-BH and CH that are capable of 230~245mhz @ 3.2~3.3V.

Nothing spectacular, but my VX needs 3.4v minimum to reach the same speeds

http://homepage.ntlworld.com/najmudd...z_3.2vDimm.jpg

I'll try lower vDimm as i continue to test these modules.

wow 3.2v at that speed is well above average

They don't seem to be breaking sweat yet, once i get back to testing these sticks i'll try them at 3.1v and 3.0v. This is my first G-Skill product and i'm very happy with them so far. My target is to get them running above 260Mhz at 2-2-2 atleast.

give em 3.8

lol, not jus yet. I'm saving that for my new mushkin redlines (xp4000).

I think not just 2-2-2, Gskill is not like some Cherry pick pair ..you will now know it. :toast:

I can officially say that there is not necessary to get the different product name to waste customer's $$. Not 1 in 10, 9 out of 10 can at least do 3.3v DDR500 :toast:

Hello OPB,

A quick question, will i void the warranty if i put heatspreaders on these sticks? They are actively cooled with a 80mm fan at the moment, but adding heatspreaders would allow heat from all the ICs to be cooled more effeciently (the fan is cooling the center of the sticks ok, its just the ends it can't get to well enough).

I'm using the same timings as in your official run at 273Mhz and they are working a treat on the yellow slots :clap:

Very good result indeed, now , you might need to have right idea about the heat-spreader,
It's really just eye candy and holding you back. It will just void the warranty as well.

Mines not, mine takes 3.43. does 260 (2.2.2.8)with 3.7volts and very lose timings :slapass:

Interesting that SPD says default timing is 2.2.2.5, but default timing on my DF4 are 2.3.2.5 and it needs 2.8 volts to do this

I'm wondering if it is a DFI issue because my Geil deaults to 2-3-2-5 if I leave it at auto even though the SPD tab shows 2-2-2-5?

yeah I would concur its the bios not the Ram, I have given up with UTT.
I so wanted 265 but alas a set of VX and Gskill BH couldnt. I have ordered some Gskill FF now

Tested lower voltages earlier, it looks like 3.2v is my minimum at 250Mhz

Here's 255Mhz @ 3.3v, i'm estimating 3.45v or 3.5v for 260Mhz. Strange how the latency has gone up from 36 @ 250 to 38 @ 255. Hmmm....will look into this later.

http://homepage.ntlworld.com/najmudd...2-2-5_3.3V.jpg

can you do trfc 12?

bh5 can do that

I'd set the wrong tref, hence the higher latencies at 255Mhz.

Here's 260Mhz 2-2-2-5 at 3.4v. Now don't get me wrong, the OCZ VX is great, but my sticks wouldn't get past 255Mhz even at very loose timings, so I'm really happy with the G-Skill GH.

Hello esdee,

I'll try trfc @ 12 jus now and see how that goes.

http://homepage.ntlworld.com/najmudd...2-2-5_3.4v.jpg

its worth tryin trtw = 1 too, gives more b/w too

thanks :toast:

Trfc @ 12, better everest latency and faster time in SuperPI. The idle timer was also changed, from 8clks to 256 clks.

Thanks esdee, now to change trtw to 1,...a little heads up would have been nice while i was in bios, esdee. lol :D

it's propably the IMC, ive seen this several times,

let me guess, the unbuff under memtest was >3300MB/s?

Yeah, when trfc = 1 I get >3300 unbuffered in memtest. I couldn't boot into windows with that set even with my VX.

Here's 260 1.5-2-2-5 @ 3.45v not much difference from 2-2-2-5, Trrd has been changed to 1.

http://homepage.ntlworld.com/najmudd..._1.5-2-2-5.jpg

nice!

i think they are tweaked down as much as they can get (stupid IMCs)

now go bench :D

Jus tried some mushkin xp4000 redlines at the same speed and the sucked. they were only memtest stable at 2-2-2-5, with the rest of the settings left similar to the GH, and they were only stable at that speed with trfc at 3 (and you can guess how ugly the unbuffered bandwidth looked).

I'll continue tweaking the GH, its still got a lot of life in it.

I haven't tested FSB at 3.5-3.6v. Hopefully those voltages will allow for 265Mhz+.

But i'll work on that 2moro :D

remember that Mushkin Redline use UTT Ch5, thus trfc MUST be set to >14

i tried it at 15 and nothing, i'll give it another shot this weekend, the GH is keeping me entertained.

250Mhz 1.5-2-2-0, trrd set to 0 as well. I still can't get trtw = 1 and boot into windows.

http://homepage.ntlworld.com/najmudd..._1.5-2-2-0.jpg

Nice... that's my experience as well. These GH are holding tighter timings, VERY tight timings in fact.... considerably tighter than other UTT out there!

C

Thanks Charlie,

The GH is certainly performing well even at "low" voltages, jus tested 1.5-2-2-0 at 3.2v and that was stable too. a quick question, does read preamble and idle cycle limit have a huge effect on the overall bandwidth? i'm only getting 7.2K in sandra at the moment...trying to bump that up.

Is this RAM gonna be AMD oriented as Mushkin REDLINE? becouse i saw only test with AMD?

I thought CH-5 has less pins.

Hmmm... BRUTAL mem b/w for 9x multi and "only" 271mHz!!!

These G.Skill GH hold their timings REALLY tight!!! Nice stuff.

Nice clocks charlie.

Jus testing the mushkin redlines and i reckon i almost have them stable at 270Mhz...jus need a few more tweaks and i'll be happy. i've learnt a few more tricks to try on the G-Skill GH from using the mushkins. I've found a few more trefs that my winnie likes :D. will report back soon.

For some strange reason, after testing my Mushkin's and sticking my GH back in i can't get 260Mhz stable even at the settings i'd used before :rolleyes:

But i was able to get 1.5-2-0-0 a try and was able to boot into windows at 200 x 11. those timings were good until 210Mhz (very unstable, but could post and run memtest). 1.5-2-0-0 seems to show 100MB of more bandwidth than at 1.5-2-2-2. Tried 1.5-1-0-0 and 1.5-1-1-1 but no post.

http://homepage.ntlworld.com/najmudd..._1.5-2-0-0.jpg

Now to try and get 260Mhz stable again....

OMG this stuff OWNZ. amd shld never adopt to DDR2 cos it sucks.

If they have to i wonder if they'll offer CPUs in two flavours, DDR & DDR2, coz i still can't see any reason to go for DDR2 at the moment. I think they should skip the entire generation and go DDR3.

I hate you guys get the better GH tan mine. :slapass:

Are all of these sticks guarunteed to run 250 @ 3.3 volts? I was trying to decide between these and some OCZ Bh-5, as I need some low latency goodness and am looking to do it with as little voltage as possible. Also, if I can hit 250 @ 3.3 then do I still need active cooling? Thanks.

most likely yes, they will do very tight timing on 250 3.3v :)

I have a dilema. I got a DC kit from another user and I can't seem to run mine at all. I've tried all kinds of vdimm voltage and even at stock 200 and everything at default. I tried tweaking up to 250 at looser timing 2.5-4-3-7 and still not able to get anything going. I've tried the 4V option and raised the vdimm all the way to 3.6V. Here's what I've tried so far. BIOS: 310, 414-3, 510-2 and Hellfire's mod 510-2. Voltage: 2.6V all the way thru 3.6V. Timing: 2-2-2-5 to 2.5-4-3-7. Got BSODs, PC keeps rebooting as soon as it start Windows. Memtest show a lot of errors.

What BIOS are you guys using? What board rev. are you using? Mine is: R.AB0. Could it be my board? Not having any luck whatsoever. Help!

Check your Dram Drive strength, Dram Data Drive Strength and Tref. For me, those are the big three. I can't pass test 2,3 & 5 when I use a "bad" tref, regardless of how much voltage. I've also noticed that when using the wrong tref, increasing the voltage on these sticks gives me more errors.

With Dram Drive strength set to 5,6 & 7 I'm stable at 250 with 3.2v and i can set Data Drive Strength to 1,2 or 3. At 260 Mhz 3.5v only Drive Strength 5 with Data Drive Strength set to 2 or 3 will work. Dram Drive Strength set to 6 & 7 would also work but I need more voltage (3.6v) at that the same FSB to be stable.

Tref. I've played with all sorts of settings here and i've found one of the best ways to find your ideal settings for Tref and Drive Strength is find timings that give you just a few errors (around 10-20) at whatever frequency in test 5. Yes thats right, for once in you should be happy to see errors in memtest :D .
Now start playing with Dram Drive strength, Data Drive Strength and Tref - one at a time. I'd start with Dram Drive strength then Data Drive Strength and finally Tref. If you finally find a good combination of Data Drive Strength and Dram Drive Strength and you're able to get rid of the errors in memtest 5 with those settings, note them down (you might end up with several good combinations) and then change back to settings that would give you 10-20 errors again.
Now try and find the most stable tref, you might find several once again, note all of them down.

Once you can pass without errors increase the frequency again and work with only the trefs and Drive Strength combinations you found. You'll be able to narrow everything down to just a few settings.

My working settings:

Tref = 2560, 3120 and 3684
Dram Drive strength = 5 & 6 Depending on FSB, 5 is the most stable at higher FSB
Data Drive Strength = 2 & 3 at 255+ FSB with Dram Drive strength @ 5

With the GH i'm able to throw very tight timings at them and they'll be pretty happy, if i get Tref or Drive Strengths wrong I ran into all sorts of problems and no amount of voltage seems to help then.

Hope this helps.

Here's a screenie of 1.5-2-2-0 @ 260Mhz with AGGRESSIVE timings, I shed off 2 secs in SuperPi and everest read jumped from 7100 to 7400 from my previous 260Mhz settings. Now, if only i could get my winchester stable at 260 x 11 i'd b well happy :D i've topped out at @ 2750mhz (250 x 11) prime stable

http://homepage.ntlworld.com/najmudd...-3120-tref.jpg

^ an excellent post!

What do you think is the max voltage you can run the G.Skill 3200 GBGH at without using active cooling on the RAM and mosfets?

Agent, you somehow describe what I'm experiencing. I also noticed that increase voltage to the memory have more errors. So, I think my culprit may be what you are describing.

You didn't mention the BIOS you are using. Could you please tell me which one you are using? I'm back to 217, which is the only one that I can get a stable system at up to 220. One I up it 230 and up, Memtest for Windows starts to toss errors at me. I'm going to play with the settings you said and see if I can OC my system higher.

Also, no matter which BIOS I use, Memtest (built-in the BIOS) seems to give me the same address 0002a425ba0. Could this be a sign of a bad/defected memory? If I use only one stick, that particular error doesn't show up. But as soon as I put two in Dual channel, the error starts showing up again, even when doing it at stock (200 - no OCing at all).

Thanks for your help. You at least gave me a lead to start I've never had this hard time doing OCing. I'm basically pulling my hair now. Hope I'm not going bald soon.

Hello jcniest5,

If you are getting errors at the same address i'd try OCing one stick at a time and compare how high they go. I've got a "bad" stick, its the only one that gives me errors at 265+ in memtest test 5. However the most critical FSB to test is 200Mhz at 2-2-2-5, if that can't pass without errors speak to OPB, he's started a G-Skill Support forum here

But i'd try and identify if its one of the sticks thats holding you back.

I've updated my sig, i'm using 510-2, and using the yellow slots. I haven't had any bad things to say about the 510 bios, it seems to work best for me.

I found out that if I use only one stick, I can OC up to 260@2-2-2-5, but the PC is not stable as SuperPI crapped out on me. I haven't tried the other stick and now I can't remember which one I tried by itself. One more finding is if I use both sticks, Memtest starts giving me errors (address) 0002a225ba0. It's always this same address every time. If I test only one stick, the error doesn't show up. I'll have to try the other stick now, too, and see if I can duplicate a no error test (with one stick only).

I've PMed OPB and we are in the process of info gathering.

What Vcore were you using at 260, 2-2-2-5? What multiplier were you using? Did you get any errors with that stick in memtest at the same FSB?

Try this, using the same stick you were able to run 260Mhz 2-2-2-5 at, run atleast 30 passes of memtest test 5. Set the multi to 260 x 9 = 2340Mhz at default 1.4v - 1.45v vCore Add the second stick at without changing the timings. See if you get errors and try noting the addresses if they appear to be similar.

If you get a lot of errors reduce the FSB to 230Mhz, which is just above your stable FSB with two sticks i believe, set the multi to 230 x 10 = 2300Mhz at default 1.4v - 1.45v vCore. Run memtest test 5 again to check for the errors with the "good" stick. Add the second stick again if you don't get any errors and run test 5 again.

The aim of this is to check and see if its just one of the sticks causing this or a mem controller issue (more to do with bios settings).

If adding the second stick gives you errors at the same address, swap the slots, and if you still get errors at the same address then its most likely to be more related to the CPU as there won't be any good or bad stick. If you are able to clearly identify the stick which runs well then its all due to the other stick holding you back

Hope that helps eliminate a few things

---

I just have to give a big thanks for that info. Using Dram Drive strength set to 5 and Data Drive Strength to 2, I'm now 24/7 prime stable at 250x11 with my current setup. I just couldn't get it 100% stable above 240fsb. Using your suggested setting, I'm now a happy overclocker :woot:.

I'm having just a slightly better luck. Am now up to 246 semi (95%) stable. The reason for saying that is because now I can run SuperPI 32MB with no error. Memtest with no errors. But when I run a Demo of 3DMark2001SE, PC crashed in the middle of it. Still playing with more TREF and other timings.

What I really don't understand why I can't relax the timing at all. Anytime I relax the timing to something like 2.5-4-3-7, my PC would repeatedly reboots (before starting Windows). I want to go all the way to 260 and relax the timing a little to get the higher Ghz out of my Sandy 3700. But no, I can't!

For me, TREF is the key. I tried many of them, 2560, 3120, 3684 and many others , but none were not stable so far. I research around for any TREF threads and I got some hints to use 4672 (not stable) and I came down to 1168, which is where I'm at now.

Got my RMA setup with G.Skill (OPB). Not sure if I should continue playing around some more or send it back so OPB can send me two sticks that work better. Any opinions will greatly be appreciated (about the RMA or not to).

Thanks in advance...

;) Good to see you're whipped those stickes into shape. 250Mhz x 11 is my fastest setup too. Now squeeze everything out of them at that 250Mhz.

Try:

TrTw = 1 - Gives a nice boost in bandwidth
Max Async Latency = 6ns - This can shed off 1 or 2 seconds in Everest Latency times.
Trc = 7 & TrFc = 15 anything lower might not please your Mushkins (CH5)

jcniest5,

I was able to kind of recreate what you were expirencing there. I reduced the vDimm at 250Mhz and tried using a tref which i've notice a lot of people using, 3120, and I started getting lots of errors in memtest 2 & 3 - But only at addresses 00022977a04 -> 553.4MB & 000244291a8 -> 580.5MB. The cure was pretty simple, setting Tref = Auto got rid of all the errors in tests 2 & 3 straight away - increasing vDimm or running 2-3-2-5 didn't work. I checked the tref in memtest and it had defaulted to 7.8uS. Which means it could have been one of these settings:

0908= 100mhz(7.8us)
1032= 133mhz(7.8us)
1168= 166mhz(7.8us)
0016= 200mhz(7.8us)

Test 5 was still giving around 10-12 errors with Tref set at auto, increasing vDimm by .07 from 3.2 to 3.27 fixed that. Drive strengths were kept at 5 for DRAM Drive Strength & 2 for DRAM Data Drive Strength.

What vCore are you using for 240Mhz+ FSB? I'm assuming you're using x10 Multi.

About the RMA, I'd try the settings above and see if they are atleast able to reduce errors at 250Mhz+. But i'd let OPB give more advice on whether RMA would be the better route to take. If you decide to stay with the sticks i'll try and see what other settings I can use to recreate your errors and come up with a few more solutions.

Hope that helps.

great tips... I managed to get my GBGH sticks up to 269.

Thanks c. I've been able to get to 265Mhz but i need 3.75v, a bit too much vDimm for me. :D

I should be getting my GH sticks sometime next week! But since I only have a 20pin power supply I can only use the 3.2v rail for now. How high are these things getting on 3.2v? I need 255-260 so how much vdimm should I be looking at?

I've been able to get 250Mhz @ 3.2v 1.5-2-2-5, and 255Mhz @ 3.3v 1.5-2-2-5. Those extra 4 power supply pins would really come in handy here for your BH5 :) .

But you can also try this to get 3.3v on your board. Its said to work with any PSU ;)

Do you have any idea how this memory performs on Nforce2 board (Leadtek K7ncr18d proII DL or NF7s2 in particular), especially the 2-2-2-5 Timings at a low voltage, up to 2.8v with a FSB at 200 or a little more? :stick:
I just went to the G.Skill homepage forum and there were people having big trouble with running that memory on a NF7s2!

I will probably just break down and get a Powerstream 520 from the egg :slapass: That should do the trick right?

that'll work well... OCZ PSU's are some of the best!

C

Would just a 20 to 24pin adapter do for my Antec PSU? Because looking at the OCZ it's just a 20pin with an adapter...

Hey buddy, great info..I think someone 's gonna doubt you're one of Gskill..lol

Ok, you got me Kev, my previous job applications were unsuccessful - thought i may as well try a different approach, lol :p:

I think i've given these sticks just about all the settings I can think of and they are holding up really well. My first pair of G-Skill and a damn good experience so far!

I haven't tried them on any NF2 board, tho i can't see why they'd not work as they are rated at 2.7v - 2.9v @ 200MHz

I got these babies yesterday and the first impression was good. 230MHz a 3v tight timings right out of the box.

I seem to be having a problem with the dividers :( Until I get my new PSU I can't run the 5v rail so I limited to about 3v since anything above my rails aren't solid on this PSU. I can boot into windows just fine with the 180 divider at say something like 10x250 that's puts my ram at just under 230MHz. This will be ideal once I get my new PSU and can give these things the juice the need for 255-260MHz. So when I put the 166 divider as soon as windows loads BSOD/reboot. Guess these are the divider problems I've been hearing about but never encountered since I was running high end TCCD before this. :(

Also what should I change here...

You can also try this to get 3.3v on your board. Its said to work with any PSU ;). 3.2-3.3v should be good for 250 which i was able to reach with these settings

Btw, nice wallpaper, where did you get that?

Thanks for the reply! I got the wallpaper from http://www.parkoz.com/zboard/skin/parkoz_wallpaper.php lots of really cool high resolution wallpapers :)

Edit: Also what drive and data strength were you using with those settings?

My RMA went through and OPB is sending me two new sticks (so he said). I will definitely play with what you recommended (did) and see how the new sticks will do. I haven't receive them just yet.

How do you raise the voltage from 3.2V to 3.27V? There isn't really a .7V increase, is there? All I see is something about .2V option (or is it .4V?), so basically a 3.2V becomes 3.22V (or 3.24V), whichever is the correct format as I have forgotten.

Also, regarding the 7.8us, all the memory modules I have, Everest is reporting that all of the are 7.8us, how reliable is this info anyway?

I'm waiting patiently for my RMA, which hopefully will be here on Thur or Fri.

OPB, can you confirm that (my RMA's ETA)?

TIA...

last time i checked these were no longer on newegg :(


will they come back?

GH memory, you mean? Probably not as BH-5 UTT is being phased out as well. They already starting making the CH-5, and Samsung TCC5, pretty soon UTT BH-5 and TCCD all will just be nothing but faded memory of the past.

So why does only the 180 divider work for me? Is this the case with everyone else or just me? I can rn 10x260 with a 180 divider just fine but when I try to use the anything below 180 I get a BSOD/reboot as soon as windows trys to start. What's upw with this?

You can try:
Max Async Latency - 6.0ns
Read Preamble - 4.0ns
Idle Cycle Limit - 0 Clocks
Trfc - 13 or even 12
Trrd - 0

You might need to loosen Max Async Latency back to 7.0ns @ >250Mhz, the same thing might apply to Trfc (12 - 14) and Trrd (2 Clocks).

My other findings:
DRAM Drive Strength : DRAM DATA Strength
The 5 : 2 combination was the most stable
5 : 3 & 6 : 2 also worked but stable only to arround 255Mhz
View this post for a few other tips on Drive Strength.

Several people are experiencing the same thing with dividers on DFI nF4 boards hence i tend not to work with dividers myself, but there's a thread on here somewhere about it.

My board seems to overvolt when it comes to vDimm, e.g. 3.27 vDimm setting in bios is actually 3.2 with +0.3 enabled and JP17 set to use the 5V rail. 3.2 was achieved by setting the JP17 set back to normal (3.3v Rail). I've modded my PowerStream to give 3.37V on the 3.3V rail tho so i shouldn't be complaining.

I've never used everest to check tref, i've always done it either in memtest or by using A64 Tweaker.

what is the highest FSB without void the warranty? :) (so 3.1V i think)
latency: 2.5-4-3-8 or something else? but 2.5..

Thank you!

Hmmmm....now that's a good question....no idea how high these modules will go. I guess that just leaves one thing - i'll be testing that 2moro to find out :)
