can not pass prime95 with optamized defaults. in Processors, Motherboards and Memory Posted August 29, 2005 TCCD samsung chips are the only 1's I've seen perform with this processor the way I believe it was meant to and even these are touchy. Are those infineon chips? From my understanding they should be windbond UTT. I also do not believe it to be an issue with the CPU not liking the ram, as the exact same hardware worked perfect in a diffrent mobo at 210mhz fsb 1:1 2.5-3-3-6 1T. Since I can run 1 stick of ram with no problems I think its a matter of this mobo just doesnt like this ram, that or there is a physical problem with the mobo. I should be able to start testing new ram to night and know by morning hopefully.
