Ok, I've read so many threads and info on people getting to 4.0ghz stable that I decided to give it a go. I followed the bit-tech guide and wasn't able to get the machine into windows at all. I lowered the BCLK to 166 and was able to get into windows once. That is 3.2ghz if I remember correctly. The cpu temp was about 64 degrees C when running prime95. On restart it would blue screen as soon as windows started. Any ideas?? I would really like to utilize the extra power this processor has to offer. I appreciate any suggestions!!
Edit: I'm not greedy, 3.6ghz would be great!!
My setup is:
thermalright ultra 120 extreme cooler
corsair 750w psu
12gb corsair dominator ddr3-1600
2x WD velociraptor 300gb in raid 0
1x WD 1TB drive for storage
22x sony dvd-r drive
xfx geforce 260 black edition
I'm running my 920 at 3.6 stable atm, watercooled.
CPU Volts: 1.28
DRAM Bus Volts: 1.65
DRAM frequency: 1443 (I also have Corsair 1600)
Qpi/DRAM Core volt 1.37
CPU PLL: 1.89
UCLK and QPI frequency: I always have mine set to the lowest, doesn't hurt performance.
Check to see if your Ram is running at default speeds
I have a few things disabled
When you changed the bios to 3.2 did you change anything else other than the BCLK, those setting might be alittle high for 3.2
try this for 3.6 works for mine, but im little higher clocked atm,
vcore 1.275-1.3 try lower first
qpi Dram 1.25
DRam Bus 1.64
Disable Speedstep, C1E, Virtualization, A20m, C state tech, CPU spread spectrum, PCIE spread spectrum, Should work like a charm,
Running same setup basically, Asus p6T deluxe, i7 920, corsair dominator, Thermalright 120 ultra extreme...
Thanks sharken & smurf, worked out perfectly!!! Now one more problem though, when the system goes into suspend mode it won't wake up correctly. Sometimes I don't get video back on resume. I changed the bios setting to repost vga bios on resume and it didn't help. Any ideas??
If I'm correct suspend mode is the low power state setting, where the computer will shut down everything but the memory?
If you go into control panel/hardware and sound/ power options/ edit plan settings, you can change it from there. I just switch my perferred plan to high performance and disabled sleep.
as for timings, the default timings are 8-8-8-24 if you didn't already know that. I know some people with dominator that have 7-7-7-19 at 1600mhz, eazy to do with 1.64v
