iammart Posted November 5, 2005 Share Posted November 5, 2005 Hi there, I've built a new system recently (see my spec) and keep getting random BSODs; I can be playing a game, watching a video file, surfing, doesn't seem to be any pattern to what I'm doing at the time and does it without warning... All my drivers are pretty much up to date, although most of the BSODs seem to be memory related (Page errors, pfn-list-corrupt...) The memory is TWINX1024-3200XL pair, on Asus A8N-SLI rev1.02 with 1011 BIOS pretty much set to default. Set to Auto, the memory timings come up as 2.5-3-3-6-2T. How come it doesn't pick up 2-2-2-5-1T, should it do that? I've had a hunt round the forums and spent the weekend running Memtest86 (v1.65). Initially I had the sticks in slots A1 & B1 as recommended, and memtest came up with occasional errors (1 in 10 passes) always around the same address in test 6. Then I tried each stick on its own in either slot, and it ran for 20-30 passes with no errors! Then I put them back in A1 & B1, it gave me a dozen errors before 2 passes were up; swapped them round and it was back to where I started....! The BIOS set to auto comes up with: Timing - 400Mhz CAS latency - 2.5 Min RAS active time - 5T RAS-CAS delay - 3T Row precharge time - 3T Row cycle time - 11T Row refresh cycle time - 14T Read-write time - 4T Write recovery time - 3T 1T/2T - 2T I guess the memory isn't bad as the sticks test fine on their own. I'm just curious why I seem to get very specific patterns of errors, and where the BIOS gets its auto settings and how to set it optimally as I'm not familiar with memory settings. Should I be able to run it at 2-2-2-5? I could do with some advice before messing around with all these numbers.... Thanks for your help, Martin :): Link to comment Share on other sites More sharing options...
