Tesla Posted December 17, 2004 Share Posted December 17, 2004 hi all, new here... I just purchased the asus p5ad2 premium (has latest bios, 1009) with an intel 3.4 ghz and 4 GB of corsair 'value select' ram (DDR2, 4 x 1GB sticks which have samsung K4T51083QB-GCD5 modules; these sticks came in matched pairs). Each of the 4 sticks checks out perfectly in memtest86 under default bios settings (no oc'ing, everything on auto). In fact, any combination of 3 of the 4 sticks works perfectly, but when I put all 4 sticks in, only 3.2 GB is reported in BIOS and memtest (instead of 4 GB). Furthermore, when I use the memory size 'probe' feature of memtest, it hangs (but only when all 4 sticks are in). One of my apps needs about 3 gigs of RAM, so I really need all 4 recognized. Also, I've noticed that memtest seems to take substantially longer than it should for a single pass (default settings) with all 4 sticks in the mobo; still trying to quantify this, though. I saw earlier that there were some PSU issues, but I know I have a solid PSU (660 W continuous, 720 W peak, entry-level server PSU from enermax) that is road-tested. Oh, and vid card is an x800XT from sapphire. Haven't even installed any HD's yet! Does anyone have any experience with this? I haven't had much luck with ASUS yet (still waiting), so anything would be greatly appreciated. All I've gotten is handwaiving about x86 architecture limitaitons and generic statements that 'some' types of RAM work with a full 4GB loadout. Many thanks for any advice, A Link to comment Share on other sites More sharing options...
