laserdave42 Posted November 18, 2005 Share Posted November 18, 2005 I bought 2 pairs of Corsair TWINX1024-3200C2 DDR400 Dual-Channel memory and installed them in the new system I built. The system would crash for no reason when doing different things, playing games, running a spreadsheet, or surfing the net. I couldn't regularly reproduce the crash until I tried the CheckIt Diagnostics program that comes with Norton SystemWorks. Every time it got to the memory test it would crash, total BLUE SCREEN OF DEATH! Of course the blue screen goes by to fast to read any error codes! I removed one pair of memory sticks, fired it up and ran the tests. It passed all tests. I moved the remaing sticks to the other slots and ran the tests again. No problems. I then removed those 2 sticks and inserted the first 2 and ran the tests. It crashed during the memory test. Moving them to the other slots and it still crashed. What do you think?

Wired Posted November 18, 2005 Share Posted November 18, 2005 Test one stick at a time in each slot using Memtest86+ and the following timings: 3200C2 Timings for 1 or 2 sticks: CAS Latency (tCL): 2 RAS to CAS Delay (tRCD): 3 Row Precharge (tRP): 3 Active to Precharge Delay (tRAS): 6 Memory Voltage: 2.75 Volts All other settings to defaults.

laserdave42 Posted November 19, 2005 Author Share Posted November 19, 2005 Well, I memtested both sticks with the settings you mentioned, one at a time, one passed the default set of tests 5 times with no errors. The other one generated errors from the start, and continued for over 2 million errors in the full range of tests, and did the same in every slot. Think I've got a bad puppy! Are those setting the recommended settings? And is it the same for 4 sticks as it is for 2? Thanks Link to comment Share on other sites More sharing options...
Wired Posted November 19, 2005 Share Posted November 19, 2005 There's no strict timings for 4 sticks, as tey only guarantee those timings for 2 sticks. Try 3-4-4-8-2T (command rate) and tighten from there. Link to comment Share on other sites More sharing options...
laserdave42 Posted November 19, 2005 Author Share Posted November 19, 2005 Can I assume the module that generates all the errors is bad and subject to replacement? And since they are supposed to be matched pairs, do I return both sticks for replacement? Link to comment Share on other sites More sharing options...
