Anyone up for some troubleshooting???

Rare1_abx · 02-15-2004, 11:48 AM

Ok heres the deal. Currrently, I am running OCZ 4000 gold 4x256. Before this I was running 2x256 and was limited to 250fsb with my 2.4c on a p8p800 bios 1014 final. With my new sticks in a 5:4 ratio I was able to make it into windows at 295fsb but was not prime stable. At a 1:1 ratio, I can only run at 250fsb so I believe it is my memory that is limiting me. I am also using a generic starlogic 450w PSU which is possible the problem??? Basically, I am looking for some tips to increase stability so I can run at least 267fsb at a 1:1 ratio. Here are some bios specs (I have tried pretty much every combination). Maybe Bigtoe could help?

This is where I am at (250fsb 1:1) anything more is unstable
Bios 1014
Spread Spectrum- Diabled
Mps Revison- 1.4
Vcore- Auto (have tried 1.525 thru 1.625 with no luck)
ICH delayed- disabled
Usb legacy- disabled
Timings- 2.5-4-4-6
burst lenght-8
vdimm- 2.85
MAM-disabled
Performance mode- Standard

If anyone has some tips that could help I would be very greatful!!!!

My guess, you need more vDimm, but are limited to what the hardware/bios will let you do. There is a hardware modification for your board that you can do to increase the vDimm you can supply the sticks. If you do a quick search here there are numerous references to the modification articles.

Why do you insist on running 1:1 ratio? I think you will obtain much greater overall performance by running the highest FSB possible, especially if you can run stable at 280-285. Unless you run applications that are very sensitive to memory function, the higher FSB will provide much more improvement in performance than will a higher mem ratio. You will need to run your own real-world benchmarks, using your own applications, to see what works best for you.

I will try some more tests at 5:4, but have been having trouble with prime95 (failing after 2min or so). I have successfully played BF1942 for almost two hours, while prime could not make it passed 2min. How importent is being "prime stable". Is there any other programs I should use to test stability besides memtest and prime?

Rare1_abx · 02-15-2004, 12:09 PM

I also don't really feel up to doing a vdimm mod. I don't even own the tools required. Anyone think it could be a PSU problem?

PCBruiser · 02-15-2004, 12:10 PM

Well, I am not particularly impressed with prime - others will argue that point. If memtest is stable, and you are stable in Windows with intensive things like video rendering, then I would say prime is not all that important. Unless you are experiencing other problems, I don't think it is a PSU problem. But check the voltage readings with Probe, mbm or in the bios.

Rare1_abx · 02-15-2004, 12:14 PM

Right now Probe says my voltages are:

12v-12.159
5v-5.053
3.3v-3.392
Vcore-1.584

PCBruiser · 02-15-2004, 12:20 PM

Then I don't think the issue is PSU related. As I said, I don't think prime is the best test of stability. And if everything else is OK, then your inability to get above 250 is more a vDimm limitation than anything else. I think you could get higher with more vDimm, but I also understand your reluctance to make a hardware modification. Perhaps there is a professional near you who would be competant to do the mod for you. Otherwise, why don't you PM bigtoe, and ask him to take a look at this thread?

Rare1_abx · 02-15-2004, 12:22 PM

This is gonna make me sound like a total Noob, but how would I go about PM'ing Bigtoe?

PCBruiser · 02-15-2004, 12:24 PM

User CP on top of the page. You will find private messages (PM) there. I think he just posted on another thread, so he is around.

Rare1_abx · 02-15-2004, 12:28 PM

Thanks PCBrusier!

bigtoe · 02-15-2004, 12:34 PM

Test your modules one at a time and try each memory slot also.

If you find you have a bad module mail me.

Rare1_abx · 02-15-2004, 12:36 PM

What settings should I use while testing them? I have never done this before so excuse my ignorance

gaddster · 02-15-2004, 12:41 PM

use the spd settings to start with as you have the golds.. ie 2.5-4-4-7

I have the same RAM and they need 2.95 to be memtest stable at 500ddr 2.5-4-4-5

Anything over 520ddr and they needed over 3v. Had them up to 560ddr at 3.15v but not for long even though they have a fan over them.

Test using spd timings and 2.85v max...run memtest or goldmem on them for atleast 1hr each...I loop test 5 100passes as this generally heats up the ram pretty good and shows any weakness.

Im going to move this thread to the memory forum as i do feel it is memory related.
