[Theo_V]

Hi guys i'm new here and id like to ask some questions about gskill pc4000 usu2.I cant run it over 255 after that i get memtest errors .In 5th test at 98 percent exactly it makes a countdown 16000 mistakes
My system is
DFI NF4 SLI-DR
GSKILL F1-4000USU2 -2GBHZ
2 EVGA 7800GTX SLI
AMD ATHLON 64 4400+X2
2 MAXTOR 160,200GB
THERMALTAKE PSU 680 WATT

I have set everthin in genie bios in not at all tight settins.I set them due to examples of yours here .I cant get it runs stable.
I have reduced the ltd at 3x .Run ram at 2.7 volts and nothins.Are there any other settings to help.I ve also used many bios and checked rams in yellow &orange slots and invidually but nothin.Also havin a blowin fan up to the memories.
So gskill technisians and other gurus of this forums any ideas.
Thanx in advance.

tested with goldmemory or memtest86 ??

I tested them with superpi 32mb at 270... no problem!!
But memtest test#5....... error at 98%!!!
only at 250/255/260/265 have not error!!!!

[Theo_V]

I tested it with memtest and it blows out errors like hell at 98% i dont know wht to do evrybody here hits at least 265 and i cant even pass 255

[grozni]

I was able to do 270, with 702-3 bios. I tried 275 no luck, 2-3 errors per pass. I will try 704-2BTA bios will modules in yellow slots. I hope I will get 275 stabil

[hiroshi976]

...... memtest running at 265....but often at 250....reboot.....blank screen...not first start boot!!
Is my kit bad?
Are compatible with nforce 4 or my asus a8n32 sli deluxe?
Why one for time in the dimm slot A1 running at least 270...... and in the dimm slot B1.....have error in test 5 at 98% of di memtest.....at less 265 ??

My system is
a64 4000+
a8n32 sli deluxe
power Seasonic s12 500w
n°2 7800gt SLI

Help me please!!

Also Me I Cant run even 255.GS Technisian we desperately need you .

[Mysterfix]

Mine will run upto 280 but I get a few errors at that speed and can't pass super Pi 32m. I'm pretty content to run them at 255 3 4 3 7 1T, they run very smooth with all my games maxed out so I'll settle for what I got until I get my dual core. I haven't tried anything in between because my cpu max is more important IMO than my memory max.

Any Settings That Could Help Us?
Also in 704-2bta bios which Drive strenth should i pic weak 1,2,3,4 or normal 1,2,3,4
Also In drive strength level 1,2,3?
Very Confused ive tried anythin

[uOpt]

Here are my settings with a pretty new kit. SLI-DR, Opteron CABYE.



These settings are not what the board autodetected, they are drived from my TCCD settings.

So you might want to try them.

Also, for me it made a big difference to reorder the sticks. I have one weaker stick and I get much higher by placing the weaker one in the slot closer to the CPU.

the 1st page of the thread has my setting for some example. of cuz everyone using different setting to run. for dat drive level you need to find it our self. different CPU mother board and ram might result different setting.

[Crappyone]

I tried your settings and Martins settings and I can't get past 255 without errors.
Now are those settings you and Martin use pass memtest test#5? More than 5x's without errors? Or do you guys only test after windows boots up with PI and OCCT and Prime? From what I've read at DFI-Street,OCforums,[H], and here with my setup and those Sticks of RAM I should atleast beable to go over 255.
Maybe I just got the unlucky sticks or something. Just not sure what to do if there's anything I can do.

If I remember correctly, I only did prime for this setting, normally under Linux except for screenshooting.

I might add a memtest run but with Samsung TCCD or UCCC I never had cases where memtest would fail on a system that was 36 hours prime stable.

In any case, the above system has been disassembled so I can't do that right now.

As a next step for you I'd say try the sticks individually (use slot 2 on the DFI).

[Theo_V]

I ve tried any settin i found in here so far so nothin the best thing i made was to get only 5000 errors in 5 memtest instead of 60000 i did b4.Im out of ideas.I tried every combination data strenght but nothin .Desperate just desperate

[Mysterfix]

Why don't you just start out with the loosest timings possible and work your way down from there. It may take a little time but it will help you figure out where your problem is.

[Theo_V]

Whats the weakest i could put data strenghts .I have tried alll at the weakest settings but some of them didint know what the weakest.Do you have any examples.Sthanx & sorry fopr all the mess.

try weak 4 and drive strength level 3

[Theo_V]

After Hours i am able to pass succesfully 260 mhz by memtest and superpi.At 265 i run memtest 5# individually i pass 1 time but then shows me some errors .Whats wrong with that.I have a 12cm fan blowin to the dimm.My ram runs at 2.7 volts under that i cant pass anything.What should i do.What tref provides good stability and ram performance.

[Mysterfix]

I usually leave it at default 3120 or 200mhz 15.6us, seems to work pretty good for me there. Try lossening up some of the other timings just a bit, maybe move them up by 1 and retest. Not your main timings like 3 4 4 8 but the ones below those.

[BioVader]

My ram runs at 2.7 volts under that i cant pass anything.What should i do.What tref provides good stability and ram performance.

I'm running at like 269 MHz with 2.5v... I have problems when i raise the voltage... Unless soemthing changed, these modules did not like higher voltages...

Mine seem to like 2.6v the best, I tested upto 2.8v but I really didn't notice any more stability from one to the other. I haven't tried 2.5 but maybe it's worth a shot.

[MikalCarbine]

If I got some of these, what are the chances of hitting 270+ HTT?
