I have a new Intel quad-core system Q6600 GO stepping, watercooled. CPU stock speed is 2.4 Ghz. I've been able to get the FSB up to 385 MHz x 9 = 3.465 GHz. But at 390-395 MHz the FSB eventually causes problems in my stress test. (My temperatures are under good control).
I have the CPU voltage control up from stock of 1.30 V to 1.40 volt, System Memory Multiplier at 2.66 or 3.00. (I have 4 Gig of high quality RAM OCZ 1150 MHz DDR2--PC1150.)
FSB OverVoltage control is at +0.10V; G(MCH) OverVoltage at +0.05.
I can get into Windows and run my stress test, sometimes for 20 minutes, but then Windows shuts down the app. Other times, on moving the mouse, I get a black screen and reboot, and so have to go back to 385 FSB.
From what I have read, 3.8 GHz CPU speed should be doable, e.g., with a fixed 9 X multiplier, I should be able to get the FSB up to about 422 MHz.
Any suggestions?

Here are all the readings that look like memory readings:
Memory timings:
DRAM Timing Selectable: Auto
CAS Latency: 5 Auto
DRAM RAS# to CAS# Delay: 5 Auto
DRAM RAS# Precharge: 5 Auto
Precharge delay (tRAS): 15 Auto
ACT to ACT Delay (tRRD): 3 Auto
Rank Write to Read Delay: 3 Auto
Write to Precharge Delay: 5 Auto
Refresh to ACT Delay: 36 Auto
Read to Precharge Delay: 3 Auto
Static tRead value: 5 Auto
Static tRead Phase Adjust: 0 Auto
Command Rate (CMD): 2 Auto

Best, CMA

It's not all about having the highest CPU clock speed possible. Generally speaking, the faster the FSB, the faster the system. There are other settings that will give better performance too, especially RAM.

Try dropping the CPU multi & increasing the CPU frequency. Set the RAM freq to run in sync with the CPU freq (i'm sure Outland will jump all over this suggestion), tighten up on the RAM timings, set the command rate at 1T.
