ok max voltage i can use is 3.4v because one stick of ram does not like voltages higher than that...
3.1v = 238 MHz
3.2v = 241 MHz
3.3v = 255 MHz
3.4v = 262 MHz
3.5v = N/A
3.6v = 275 MHz (with only the good stick of ram)

Thanks Wingz :), results and averages updated
Just moved to DFI nF4 SLI-D.
My results so far: (2x512 this time, of course)
3.3v = 258 Mhz
3.4v = 262 Mhz
Any higher voltage, and I'm getting tons of errors even at the speeds listed here. Any ideas why? The fan is blowing over the rams, so they shouldn't overheat.
mrlobber, try then individually like Wingz did... maybe only one module dislikes voltage.
Nice improvement over nF2 :toast:
your previous resultsQuote:

can you try 3.1 and 3.3v also
everything in DC ? :toast:

what mrlobber said is higher VOLTAGE causes errors, he is stable there with current voltage
oh i understand now....Quote:

just checked them ....they're 44D and KO 6633
these averages are so on the money its not funny :p:
AVERAGES
3.1v = 237 MHz (from 8 results)

Great job with the thread
Well, a little update.
All of a sudden this morning memtest gets out some errors and then FREEZES at @ 260x10 3.4Vdimm where previously it was able to loop more than 10hours of th #5th test error free. Haven't tested lower, but I suspect, I might get the infamous "sudden clocks drop on VX" some people have already experienced. Of course, I need more testing to confirm or deny this, but the point is, at the moment now my combo is not memtest stable at the speeds and exactly the same settings where it was before (and ambient temps have not changed either, they're even a bit lower). Interesting...
mrlobber,
I suppose you have a fan blowing on your memory to keep the heat down? Heat kills!
Has it been warmer in your area and possibly is something else acting up? I know that if you use the 5v memory feature on the DFI NF4 it can create tremendous heat, so be sure to cool the board in the power section with the heatsinks also.
2 X 512MB TMSP ~ AA4T ~ 0503 ~ 44D
Motherboard ~ Abit AS8 (i865PE)
3.25v ~ 200 FSB
3.30v ~ 209 FSB
3.35v ~ 225 FSB
3.40v ~ 250 FSB
3.50v ~ 253 FSB
3.60v ~ 255 FSB
This latest result obtained after 12 hours burned-in at 3.5v/250 FSB. The chips getting better each day after more burned-in. Now, I am looping test #5 at 3.6v/255 FSB for at least 8 hours more. Hopefully 255 FSB is not the end of the journey. The only problem is the OCZ DDR Booster fluctuated as much as 0.15v. I am dreaming of Hipro5's Maximizer.
Andy, thanks for the heads up.Quote:

As I said, even the ambient temps are lower.
Yesterday, it run 10 hours (during night) 261x10 completely error free. Today, EXACTLY at the same settings, it gave out a dozen of errors during the first 10 passes, and then froze. I rebooted fine, lowered the fsb by 2, leaving everything else untouched, and it froze again. Then I had to rush to work, but that doesn't feel good at all.
my VX replacements will be here today WOOT WOOT!:D i wsill be suer to test the shizza out of them...
mrlobbler:
maybe some more volts are in order?
could be a result of the burn in that the chips need more volts to run at previously easy speeds, ive heard of that before, my bh-5 did 255 at 3.3v and then when i went up to 3.6 270 was easy, but when i went back to 3.3 i could no longer perform at 255...it now took 3.4 for 255...
now i think that memory is dead though so i havent been able to prove that theory properly, its just something you might want to try.
andyOCz you were just saying alot of these modules are loseing the lower speeds.. like my 3-3-3-8 wasnt stable with 2.9vdimm and my 2-2-2-5 wasnt stable till 3.2 then 3.2 was good all the way up tp 252mhz... this ram is evolveing :toast:
then i ran into this problem>>> http://www.xtremesystems.org/forums/...ad.php?t=52766
also RAB* you didnt ever update when i got 260mhz with 3.6 on the last set :toast:
will you be adding this new set to the results too?
running 2-3-3-8 2.7v to mine at the moment, working fine.
Awesome, post. Very helpful info.
I prolly shouldn't ask here but where does one get Twinmos UTT in the US? Although it looks like I will buy VX.
My Corsair 4400C25 turned out to be a big disappointment. :stick:
2x512 UTT fed 3.5v using RAM booster on Neo2

Once i get my new psu (hopefully today) Ill definetly be running tests all day :D
^^^yeah thats what i thought till i got a bios checksom error :mad: cant figure out wtf is wrong. :stick:
I will add all the new results including your 260 MHz @ 3.6vDimm.. jus need some time.Quote:

Reason I ask is it seems my modules are loosing their 3.1v speed at the moment... although temps here are 25c-30c right now so it would well be jus the temperature.
I used to be stable at 248 MHz 3.1v 2-2-2, now 240 MHz gives errors at same settings... funny thing is at 3.2v they started off being stable at 256 MHz and not even close at 257... now I can run memtest on 257 for bout 30 minutes before i get errors, and this is with the same high ambients.
eh? where can i read up on this? strange i had the same thing happen to me, i was running 260mhz at 3.4v then one morning it was unstable, had to bump vdimm up to 3.52v then all was well.....Quote:

And it wasnt giving me enough voltage, so I unplugged all except my pump, 2 ram cooling fans, and my radiator fan and floppy drive
Im currently burning in at 3.2volts at 255mhz but im getting 2 errors every loop so
I'll post some official results once I get my new PSU
You guys think I should jump it upto like 3.5 volts for burn in? or gradually get to 3.5?
Gonna do 3.3 tonight while im at work so
