Geil Memory failing memtest

JC · 4 Feb 2007 at 23:47

I have a set of Geil 2gb PC6400C4 800mhz that was purchased on Jan5 07, although the computer has been working fine for the majority of the time I have had a few BSOD's and unexpected crashes from games.

I found out that people run Orthos to test for stability, this brought up an error after 2 hours.

I ran memtest86 (dos version) overnight to see if the problem was specific to the ram. I'm running the chip at stock at the moment.

266mhz fsb, ram 1:1 4-4-4-12 timings, +0.2v set, gave 13 passes and 5 errors overnight.

266mhz, ram 1:1 4-4-4-12 timings, +0.3v set, gave thousands of errors.

I'm suprised as I thought increasing the voltage would help, particularly as I'm only increasing volts within the rated limits.

Is this an immediate sign that something is faulty?
Is it necessary to perhaps lower the voltage to stock or +0.1v to test?

Without any spare modules here sending anything back for RMA is a bit of a hassle, but in particular the last thing I want is for them to be sent back as "ok", is there anything else I should test?

I got my 2x512 GeIL 6400C4 ULL ram on 27th dec and it is also faulty, I have tried 4-4-4-12 at Normal, +0.1v, +0.2, +0.3, +0.4 and it produces around 1-5 error per pass.

In the process of attempting to RMA.

I had to lower my voltage to 2.00 to get it to run @800mhz 4-4-4-12 without erroring in memtest.

Not sure if its related to the memory but i am getting BSOD every now and then (mmpool device driver or something).

Doesn't sound right to me. It's not operating as designed that's for sure. I'd explain it to them the way you have above and RMA them.

cheers

Yup, RMA them. Memory should never error within specs.

sorry to resurrect the thread but if this helps anyone then it was worthwhile.

Following on from the above mentioned problems I lowered the voltage from 2.1v down to stock volts now and the PC passed 24 hrs of memtest and 70 hours of orthos.

When you say you lowered the memory voltage from 2.1 what did you set it to ??

Also are you running still at the settings on the label 4-4-4-12 and do you have it set to 1T or 2T

Thanks

We could do with a standard thread for the setting up of this memory and I am supprised that someone from OC has not done this yet

The memory is now set to +0.1V which I believe is 1.9V up from 1.8V, this passes memory tests unlike the settings at +0.2V or +0.3V.

I am running at 4-4-4-12, its an intel chip so I dont know anything about 1T or 2T?

Thats the same for me im running mine at 2.0V to pass memtest, 2.1 gave some errors, 2.2 gave even more errors and 2.3 gave thousands of errors. I havent tried 1.8 or 1.9 yet. As a matter of interest what mobo are you using? There seems to be some vdimm probs with the p5b deluxe.

Sounds simular to my problem Try running it at 5.5.5.18. I have this ram and it doesnt seem to want to run at stated speeds. OC have agreed an RMA but i am not sure its worth the effort. As it auto selects the settings above on my board and memtest runs 30+ passes without a glitch. cant get more than 2 passes at the stated speed.

The board is a Gigabyte 965P-DS3, seeing as I can get them to pass at 4-4-4-12 now I'm not going to loosen them to 5-5-5-18.
