2700LLPT TwinX 1 Module Possibly bad.

[mnarciso]

I've got 2700LLPT TwinX Modules. I have tested each individually and I have one stick that generates 59 errors in memtest86 on 2 computers and it is always on the same test. Test 5 generates errors in the 495-511 MB range.

 

It would be extremely hard for me to send in both modules, would it be possible to send in just the bad stick? I've had one of these modules replaced before and that didn't seem to be a problem however recently I've had to send in both as instructed by one of your staff there.

 

Problem with me sending in both is I will be computerless for sometime and I can't have that happen.

 

Anyway I may have timings set incorrectly. I have an A-Bit NF7-SG2 nForce2 board. Please advise.

CAS Latency: 2T

RAS to CAS Delay (tRCD): 3T

Row Precharge (tRP): 2T

Active to Precharge Delay (tRAS): 5T

2.75v

 

Make sure your FSB and mem speed are in sync. You can definitely RMA only one, however they can't guarantee the best timings with the old and the new because they won't have been tested together. Definitely list on the RMA (when it's approved of course) the version of the memory so they can try to match that.

Thanks for the suggestion actually I lowered the timings according to the guidelines at the XMS and Qualification Testing thread, to 2-3-3-6 and there were no errors on a single stick. However when I combine both sticks for Dual DDR on my Shuttle XPC I get errors. I have to lower the timings a bit to get 0 errors. Maybe the voltage is not correctly set. What should the DDR voltage be at for these sticks?

The recommended voltage setting will be 2.7/2.75 volts, depending on the option that you have on your MB BIOS; the maximum voltage that you can set it to will be 2.9, anything above 2.9 volts will void the warranty.
