G.Skill 2GBHZ with DFI Expert mobo Testing

I know many people has some problem with DFI Expert mobo. i discussed with Oskar Wu many time about this also, but no idea....

finally yesterday night i spend few hrs to tweak around with my new expert mobo (the 2nd batch, not the 1st batch with "cut" around sound output area).

at first i cleared its bios and plug the 2GBHZ. it refuse to boot into bios. it freeze on DFI logo screen. then i took out one of the stick and only left one on the mobo. it boot into bios no problem. after i finished the bios seting i turn off computer and plug another one. it boots fine no problem. cleared bios and boot dual channel again... freeze. btw my bios is 1207

ok the bios Data level is set on 3(1~15) and 1(1~4), different CPU mobo might need different level. the way i tested out is using FSB310 DDR620 with 1GBFF 2.6v 32M. since expert board is hard to go over 310 this is the great way to find the best level for me. from 1-1, 1-2, 1-3, 1-4, 2-1.... to 8-4; many level i can not even boot into windows but for 3-1 i could do 32M to loop 8. that is why i think 3-1 is the best for me.

DDR500 testing in expert board!
although i knew UCCC only need little voltage to run but..... this low???

below is overclock testing and overclock is not guarantee :)

those timing is set on bios, i didn't use A64 to change any timing

Conclusion

expert mobo is different than ultra-D mobo

the timing for ultra-D is very hard to run twtr 1 and trtw 2. normally we use twtr 2 and trtw 3.
but on expert mobo, twtr 1 and trtw 2 is working fine... and if lower twtr 1 to 2, system becomes unstable and BSOD sometime the only thing to help system stable is lower trtw to 3.

also, singel channel for 1st boot after clear bios is needed. once bios been set, dual channel is ok. (at lease in my case)

finally! UCCC is cool for low voltage...... :)

also! this kit's SN# starts 06010510

290 @2.4v....holy moly!! nice finding...I'll received my HZ tomorrow, can't wait!!

try DDR500 low voltage 1st, increase slowly :)

sick results :slobber:

These go even higher with higher vdimm?

Thanks for the info

i try up to 2.7 but still not 300 stable! maybr max out at 295 i think :)

WTF....only 2,4v for 290Mhz ....:slobber:

G.S Technician

For Ultra-D, what bios, tref, and dram drive/data strength do you recommend? thanks.

it is good to see the G.S guys on here.

My next pair is definitely going to be those G.Skills!

I also heard you guys have excellent RMA process. I look foward to testing and using your product.

It was a bit shifty there for awhile but i'm sure it is better now.
Thanks for the testing my next board will be the expert.

290MHz and only 2.4v is sweet! :up: I remember using 2.5v with kit I have here, on Ultra-D and it worked great up to almost 290MHz. I wonder if it's Expert/HZ combo that work so great or maybe Ultra-D could also pull this off... But as far as I recall, Ultra-D doesn't have 2.4vdimm option... :(

for ultra-d i use 7 (1~8) 3 (1~4)
tref is 3684
i hope this will help you

G.S Technician, Is 3684 the tref value you were using on the expert as well?

yes :)

Nice results man. I've got HZ on an Ultra-D and your products don't disappoint. :toast:

ben, since u ar using the sam board (a8n32), could you post the resualts with this gskill's. i'm in the process of buying this kit, but i heard that asus is having some incompatibility issues with UCCC chips, and that this kit is not capable of runnig even at rated speed - 250MHz..please lemme know

Gr8 to see some official demo/help to get those 2 GB going on Expert. Nice clocks for sure at those volts. May be I am getting those then.

fine!
i'm trying (without troubles) a pair of GBHz on my Expert mobo @250Mhz 1:1 3-4-4-8 @ 2.6v.
i'm running my system without hdds and readers, so i can test only with memtest86+!:p:
now i hope to see how my memories work @2.4v!

EXCELLENT! our timings are identical up to 270, and I think you just solved my problem for 280-290!

Now if I could just leave work and go try them...

Did they pass 32M at 280 and 290? If you didnt try, could you do so and get back to us?

Thanks again!

Can you PLEASE explain to me the logic and/or math behind using 3684 as the TREF value?

thanks ahead of time!

Yoo, G.S. Tech! What about the 1st batch of GB-ZX on the Expert? :)
Have you tested it on the mobo yet?

i don't know what but 3684 is my lucky number lol
and 2GBZX on expert it about the same as ultra d :)
alos i did post the 32M for 280 290

Hmmmm, this really blows. Got my 2 GB G.Skill today, and can't get them stable above 265 :(
Have tried all the settings in this thread and other threads....
I can't believe I am THIS unlucky...first I get crappy Redlines, and now crappy gSkills too :(

All you so-called technicians posting you great memory overclock result on boards like these....are you just using handpicked modules after testing alot of similar type modules to get the best OC results so people like myself will go out and buy your company's products, but not get nowhere near the same results?
I know that hardware setups differ, etc.. but it's is really frustrating to invest in a second pair of 2X1gb modules and not have them perform nowhere near what other people are reporting...
Sorry for the tone, but it just pisses me off that I should be this unlucky :(
I was debating with myself wether to go for g.Skill or Crusial, and after reading good things about g.skill and crusial modules giving up after a few months I decided to go with g.skill....and had really hoped to be able to go to the same max as my cpu (280-285) with these modules...but no :(

I haven't tested each stick individually...yet...maybe one of them is worse than the other...?

Also, how come some values will work in A64Tweaker, but pc won't boot with the same values entered in BIOS?

yes this is hand pick 2gbhz from around 15 pairs

the average of this should be around 260~280 with active cool even better!
lower voltage 2.6v is good already, adding more voltage is no good at lease you see significant MHz imporveing

well, if using handpicked modules, it isn't exactly a fair test to put forward, is it?
I mean, we as consumers never get the chance to handpick our own modules.
Active cooling? but these sticks are not warm at all, and I haven't tried more than 2.66 vdimm on them anyway....
It jjust really sucks having the second pair of 2 X 1 Gb sticks not even come close to 280 :(

It is not very hidden that some of the results presented here are from slightly (or less slightly) picked sets.

Many people on the forum buy multiple pieces of whatever item they want, keep the best clocking one and sell the others on ebay, so it is not too far off.

For what it's worth, I got a HZ kit normally off newegg and it goes pretty well, 270 MHz. One stick is weaker but I haven't bothered looking where the better one goes.

That is common. Everytime I give somebody with same board and memory A64tweaker values the result is a such a violent crash that a CMOS clear is needed even on the DFI boards.

Many of the A64tweaker values are mostly dependent on the CPU's memory controller, that's probably the reason.

This should be the first line of all your OC results threads. It should be in bold and a large font so everyone can see

ya, dont be too upset man, after all, you are getting above and beyond the advertised specs, and luck is always a factor in OCing! (although I do agree that the GS tech should have mentioned the 15 sets it took to find that pair...ahem!)

That said, i cant get mine stable above 270 to save my life either... a shame too since my beautiful CPU hits 285 on air without sneezin'! ahh, oh well... life goes on! When they come out with DDR600 2GB sets, it will be allllll good for everyone!

NOTE: this is my attempt to push Gskill into releasing some DDR600 2GB kits ASAP! Take the hint and get us some supersticks man! lol...

oh come on, you mean to tell me that the engineers at Gskill cant explain why 3684 works best? lol... i figured if anyone would know the deal with TREF, it would be you guys! sheesh...

heehhee i don't really know it but i guess it is something about the electrical data sine wave which give stronger singal

Do you have any information regarding new kits OC potential ... are the bad batches out of the way

i think the 0601 one is kinda good tho...


and
ASUS mobo has big problem with UCCC, not even with G.Skill....

Can you tell me which memory company is not hand pick? OCZ, Mushkin, GeIL, TeamGroup, Corsair, Crucial?

All hand pick for testing. lolzzzzzzz
