Asus Rampage with E8500 @ 4.2GHz Reboot/Hibernation Issue
Hi,
I recently built my new PC with Asus Rampage/E8500/2Gx2 G Skill DDR2 1066. This combination provides one of the most pleasant new-build experience mostly come from Rampage's quality and flexibility.
As expected, reaching 4GHz is quite straight forward. However, extending to 4.2GHz brought issues most relating to reboot and hibernation.
1. The PC sometimes had to boot or reboot 2 times to got into Windows.
2. Sometimes fail to restart from hibernation (right before windows show up).
3. Super Pi (1M?) tends to crash the PC right after restart from hibernation.
The new PC is very stable at 4.2GHz and passed Orthos (CPU and RAM stress) , Super Pi 32M, PCMark and 3DMark when it boots successfully.
My BIOS setup:
FSB = 443MHz
Multiplier = 9.5
FSB Strap = 333 MHz
DDR2= 1063
CPU Volt = 1.387V (BIOS) / 1.368V (CPUID)
CPU PLL = Auto
NB = 1.55V
SB = Lowest Volt from BIOS
RAM Volt = 2.04V (As suggested by G Skill)
Loadline Calibration (LLC) = Enabled*
AI Clock Twister = Auto*
CPU GTL = Auto
NB GTL = Auto
RAM Timing = Auto (As suggested by G Skill)
I know many people suggest to disable LLC. I found that, by disabling LLC, I had to increase CPU voltage by ~0.04V but I see no difference in terms of stability since my machine never crash when it is idle. There I decided to keep LLC enabled.
AI Clock Twister affects stability a lot. When I set it to "Strong", the chance of failing reboot is higher than "Light".
Any suggestions? The SuperPi(1M)-after-hibernation crash actually puzzles me the most. It (seems) indicated some devices may are not initialized properly after restart.
Thanks in advance!
