Sarkk47 Posted September 22, 2008 Share Posted September 22, 2008 greetings, i am running two kits of TW3X4G1600C9DHX memory (4x2gb) in an asus p5e64 ws evolution. the bios version is 0602 and i have an intel q9550 non-oc'ed. in the bios under the AI Tweaker menu i changed the following settings (all other are on auto): DRAM Frequency: DDR3-1333MHz DRAM Timing Control: 9-9-9-24 DRAM Voltage: 1.60V i have tested the ram (each single modul and all four of them) with memtest and it did 2 passes with zero errors. my problem now is: i can install vista ultimate x64 without problems (i have to remove 3 modules for that), but once i install SP1 and various drivers (chipset driver x48, intel matrix manager) vista wont boot anymore. it gives me a BSOD before i even get to the logon/welcome screen with the following error: STOP: 0x0000007E (0xc0000005) and goes into an eternal reboot/BSOD loop. when i turn the computer off completely (pull the plug) and turn it on again, it usually seems to boot just fine. reboots from vista itself are also fine. just when i cold boot it the first time it seems to produce the BSOD. (and needless to say, it does not happen with only 2 modules equalling 4gb ram.) so my assumption is the settings for the 4 up configuration arent ideal and cause the BSOD when booting vista. im not an expert of ram timings and various other settings and i dont want to fry my mainboard by overvolting it. i dont want to OC the cpu (4x2.83ghz is fine) or the FSB (1333) and id be perfectly happy if the ram runs with either 1333 or 1066 as long as its stable. i would appreciate any assistance in this matter and be very glad if someone could point out bios settings to make the 4 up configuration work. the entire system (cpu, gpu, northbridge and mosfets) is equipped with waterblocks btw.
