Hi.
I had some issues with my PC resulting in a CMOS reset and I can't remember how to set up my RAM timings as they were.
MB: ASUS P6X58D-E
CPU: INTEL i7 950 3,06 GHz
RAM : CORSAIR 6GB DDR3 INTEL I7 DOMINATOR GT 2000MHZ CL8 (CMT6GX3M3A2000C8)
Initially the RAM speed is 1066 MHz but as my RAM is able to go faster I thought I could change some values in BIOS to make them go faster. Ufortunately my PC doesn't seem very stable when I try and fiddle with the BIOS settings. So I need help.
From what I've learned the supported speed is 1066 MHz hence the default value I guess so when I change the values it's considered overclocking (one of my ASUS programs tells me that).
I tried entering the BIOS sections "DRAM Timing Control" and enter:
DRAM CAS# Latency: 8
DRAM RAS# to CAS# Delay: 9
DRAM RAS# PRE Time: 8
DRAM RAS# ACT Time: 24
Everything else is on AUTO - but nothing changed - perhaps because the Ai Overclock Tuner is on AUTO aswell.
Both my board and my RAM supports X.M.P. so I tried the X.M.P. profile: X.M.P. Profile Info: 2000MHz-8-9-8-24-2N-1.65V-1.25V
My PC fails the memtest after about 2 loops (1½ hours) - one time leading to a corrupt BIOS. And Prime95 crashes almost instantly.
I then tried lowering the BCLK value so my CPU reached a more accurate frequency and memtest was stable after this but Prime95 still crashes - just not at once.
I then heard that setting the Ai Overclock Tuner to MANUAL is better than the X.M.P. profile even if the values are the same. I tried this but the Prime95 stille crashes .. well it frooze my Windows.
I tried using this article: http://vip.asus.com/forum/view.aspx?id=20081220191040237&board_id=1&model=P6T+Deluxe&page=1&SLanguage=en-us but I'm having a hard to understanding what does what and I'm affraid to fry the CPU or similar.
I'm hoping someone can help me - perhaps if you have a similar system (se hardware in the top).
These are my BIOS settings when on X.M.P. profile:
