Since my i7-970 [TC] has become a problem child I have been trying to get my 2600k rig competitive.Flower
ASRock P67 EXTREME4 GEN3
Intel Core i7-2600K
G.SKILL Sniper Series 8GB (2 x 4GB) DDR3 1866 Memory
XSPC RX360 Radiator w/Push/Pull Fans, EK-Supreme HF High Flow Block, Swiftech MCP655-B Pump
I OC'd to 4.8 GHz and in Window 7 P95 Blend ran for 1 hour and 1 SMP WU completed with no errors.
I then tried to install Ubuntu 10.10 but had install problems. I then switched to Ubuntu 12.04 and had similar problems.
My first conclusion was the OC was the fault. I was correct. I then set the rig to stock and installed the Linux distro that was currently in the DVD drive.
That just happened to be 12.04. I was able to install/update and get my folding and HFM apps installed.
I then was then able to get the OS to boot at 4.7 GHz but not 4.8.
I slowly increased the vcore until I could boot 4.8 GHz but the folding client kept crashing.
Finally this morning I have made some more changes. I was using offset but have now switched to fixed.
This from my current BIOS settings:
CPU Ratio Setting: Manual
Max Ratio: 48
Internal PLL Overvoltage: Enabled
Intel SpeedStep Technology: Enabled
Turbo Boost Power Limit: Manual
Short Duration Power Limit (W): 255
Long Duration Power Limit (W): 255
Long Duration Maintained (Sec): 1
Additional Turbo Voltage: +0.016
Core Current Limit: 255
Host Clock Limit (BCLK): 100
Spread Spectrum: Disabled
Power Saving Mode: Disabled
CPU Core Voltage: Fixed
Voltage (v): 1.365
Load-Line Calibration (Level): Level 2
DRAM Voltage (v): 1.5
PCH Voltage (v): Auto
CPU PLL Voltage (v): 1.890
VTT Voltage (v) (Max: 1.2v): Auto
VCCSA Voltage (v) (Max: 1.2v): Auto
This is my first SB.
The folding client running a SMP A3 just hit 80% so I'm going to take a chance that this WU will
Any suggestions? If anyone is running something similar I'd like to known how you reached 4.8 GHz or beyond.Edited by msgclb - 7/25/12 at 10:13am
