Well, I'm in an odd situation right now. I just got a new stick of Crucial 256MB PC133 CAS2, and I'm finding that my system has an issue with 3 DIMMs. My mobo, a Soyo K7VTA(KT133, "A" Southbridge) has been sitting with a 128MB stick of Kingmax "PC150"(aka PC133 CAS2) and a stick of Crucial PC133 CAS2 for a while now, and today I threw in the new Crucial stick, only to have it fail to boot. After some RAM reorganization, the problem appears to be that the machine only fails to boot with 3 DIMMs installed. Any 2 DIMMs in any order, any slot will boot fine(which means the new Crucial stick is good), but adding the 3rd DIMM causes it to fail to boot.
Thinking it was the memory timings(I'm running the mem at 133mhz, CAS2, 4-way interleave; which all sticks will run fine at), I took everything down to the bare minimum(100mhz, CAS3, no interleave), and gave 3 DIMMs another shot. The machine made it through the POST the first time, but BSODed while loading WinXP. Rebooting it for a lark, the machine only made it through a partial post the 2nd time around, giving a garbled POST screen on the second POST screen(the screen that follows the RAM count, HD detection, ect).
I've sent an email to Soyo tech support(although I don't expect that they can do too much), but as I figure, I'm up the creek per-say, so I'm looking for some advice. Does anyone have any experience with this issue on this, or any KT133 based mobo, or mabey some general advice? While I'm only down 128MB(remember, stable with 2 sticks, so I took out the Kingmax), I'd really like to get the most for the parts I have here. Thanks.
