; well their PSU is only 300w under DFI ultra-D. I bet user can easily get onto DDR540 by a good testing enivornment especially a good 450w PSU along with a good memory controller.

:)

Thanks for the reponse.1. I am banking on my motherboard being the culprit because it will clock up to 280 in 2T with no errors. After massive amounts of errors I gave up on memtest and started using dual prime and superpi 8m for windows xp testing. As I stated previously in 1T, even @ 250 Mhz it will fail SuperPi 8M.

2. I have only given these sticks a voltage of 2.6 and 2.7.
3. As far as my PSU. I have a Silverstone Zeus ST56ZF, 38amp single 12volt rail monster.

Thanks again for your R&D with the Microns.

Yeah, Ben. Thanks for the info but I think these are different Microns.

I'm beginning to get the same feeling about DOS Memtest. I've been trying for almost a week to get some HZ memory to run at 270 in a Venus board. I found settings that are completely stable in Memtest #5 and #8. But with a 1/1 ratio the memory errors out after a little over 2 hours time and again with dual Prime95. Finally found a setting that was both Memtest and Prime95 stable. After 7 hours of Prime I decided to tighten up the timings. I made one change, ran Memtest #8, and almost immediately starting getting multiple errors. Changed the setting back and the errors are still there. Input other configurations that I found that were Memtest stable and still got errors. Went back to the settings that were Memtest and Prime stable and still more errors. Running dual Prime for several hours now with these settings and so for there are no errors.

Try the windows memtest http://hcidesign.com/memtest/

My sticks just arrived. I'll test them on my sig rig tonight.

Ozzi, the last two posts of screenshots our prime shot was at 2.76v and the last shot your posted as 297 was at 2.83v. Are you reccomending an advantage at 2.83v? I thought earlier everyone sated that above 2.7-2.75 didn't help?

Just try the different voltages.. not all sticks perform the same.. you have to feel the limits of your sticks can do.. not expect other people to tell you how to use your sticks

the extra voltage helps with shorter benches for me, though to a point. 2.8v is that limit. my board reports a touch high.. haven't actually measured vdimm, but that 2.83v was 2.8v in the bios. 2.8 +.03 give ~2.86-2.87 in smartguardian.
when doing long term stability, it seems that the extra heat it produces makes the voltage benefit kinda worthless. i'd like to see what these sticks can do with a bit of cold CO2 ;)

Bad idea - the BP PCB is only spec'd down to -10C. That's why I sometimes have issues with my Expert's ram positioning w/ my autocascade....:(

how about just good old fashioned Big aZZ fan? :woot:

that's what i normally do, got a 120mm blowing down right over the sticks.. :D:D
but the thermal conductivity of the plastic housing that the actual IC sits in is pretty terrible, so i was thinking of taking active measures against it. too bad this stuff doesn't come in wlcsp instead of tsop :D

Other than a fan over the ram, I wouldn't expect anything more than maybe a mhz or two difference from any better cooling. With a fan and 2.8v the ram doesn't get hot enough to make any difference at all from what I have seen and niether do the spreaders. You could take them off and see no real difference at all as long as you still have a fan over the ram. If this were not the case, you would have seen lost of other people soing more than fans already. It simply doesn't help. that said, maybe with BH5 at 3.6-4v it would certainly help, but not on sticks at 2.9 or lower.

oczy, is the date on the sticker or only the ic's? What does 0610M on the sticker mean?

my experiences with micron make me strongly disagree.. temps play a huge role in how high of an oc i was able to get with my older ballistix. haven't really gotten these sticks chilly yet, but i plan on doing so soon.

also, the date...
on the actual IC's, it says 0538
the sticker says 0551M (not sure what the M is for) (edit: also not 100% that it really is a date, but i think it is)
SPD says week 50 of 05

i guess it's all relative. i'd be most concerned with the IC date. ;)

I'm guessing the sticker 0551M is the date/week of the module manufacture and the ic date/week is 0538 or whatever week went into that particular batch.

My results:

Yes I know 2.9v is danger territory with micron chips... but I couldn't get em stable at 2.8v. I'm gonna try 2.8 with 0.3 over and see.

Thats 4 hour BF2/WoW stable BTW. So these sticks, thankfully have no 3d bug.
03-13-2006, 03:26 PM
ozzimark

what drive strengths?

also, i found that anything over 7-14 for trc-trfc just lowered stability. same with some of the other secondary timings, higher isn't always better... it's be weird if there is that much variation in what 5b F likes.
03-13-2006, 04:35 PM
Tibu

I'm using 8-2 strengths.
03-13-2006, 05:55 PM
ozzimark

and they consistantly give the best results for you? :confused:
03-13-2006, 05:56 PM

try switching them up and see if something happens.. ;)
03-13-2006, 05:59 PM
Tibu

Switching them to what?
03-13-2006, 06:01 PM
nn_step

It means just try different drive strengths because some ram perfer different drive strenghts compared to other ram..

If they are anything like Ballistix, try 7/3 7/2 7/1 5/3 5/2 5/1, weak settings
