Memory/System Stability

Recommended Posts

I'm currently running a PT800CE-A ECS motherboard with a Pentium Prescott 3Ghz processor. I recently upgraded from 2 sticks of 512Mb DDR400 to 1Gb of 2 sticks of Corsair Valueselect DDR400. I started getting blue screens after I upgraded my memory.

The ECS website cited problems with this motherboard when using 2 sticks 512Mb of DDR400 with a Prescott 3Ghz processor. I updated my BIOS accordingly.

I'm positive there's nothing physically wrong with the memory modules...I had them RMA'ed from the vendor, it's not likely to get 4 sticks of bad memory.

I read the other threads on this site and I set the DIMM voltage to +6%. After I changed this, I still get blue screens, but they occur rarely.

I was wondering if there are other BIOS settings that need to be changed, such as:

Dram clock (by SPD) Timing (Auto by SPD) SDRAM CAS Latency (2.5) Bank Interleave (4 Bank) Precharge to active TRP ( 4T) DRAM Command Rate (2T Command) Auto detect CPU clock (enable) CPU voltage Reg. (default) DDR voltage reg. (default)

Basically I think I'm having the same problem is the one is this thread:


Any help would be appreciated. Thank you.

Please test the modules one at a time with http://www.memtest.org and I would set the Dim Voltage to 2.75 Volts (+.10%) as well. If you do find one failing then lets get it or them replaced. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!

However; if you get errors with both modules, that would suggest some other problem. And I would try testing the memory in another system to be sure. In addition, I would maybe try the system for a few days with just one module and then do the same to the other so we can see if we can isolate this to one of the modules. But I would suspect this to be an issue with the MB or PSU.
