Been busy all day, haven't had time to reflash at stock settings.
Actually, I had the problem too...

Well SLACR is the G0 revision, so that shouldn't be the problem, but if it isn't the BIOS... It does look like a heat problem if the rest is fine (since upgrading to a better cooler fixed the problem untill you up'd the voltage again => heated it up more).

I would also like to add that my QX6850 would be unstable if I ran it higher then 58C (rated up to 64C), so maybe you have a simular problem with heat making it unstable and doing strange things (even tho its rated up to 71C)...

Did you check your temps with different software tools? Some report lower or higher depending on your mobo/proc.
Try HWMonitor/CoreTemp/RealTemp/Everest and see if some of them report higher temps.
I've used Core Temp, Everest, HWmonitor, and Rivatuner with the C2D/C2Q Plugin. They're all the same.

Heat is NOT the problem. I've already posted about it, but I'll say it again. When I had this problem the first time, the CPU was trying for 3.5Ghz with an ASUS cooler and temps were hitting 67C before the multiplier drop kicked in.

With my TRUE, this only started happening when I was trying for 3.6Ghz, but my temps are only 61-62C when the multiplier drop kicks in.

Unless my Q6600 decided to magically change the Tjunction or whatever the limit on temps are before Thermal Monitor kicks in after changing to a TRUE, this is one huge annoying pain.

I noticed that the multiplier drop kicked in when it was 62C and it never was allowed to hit 63C. For my previous ASUS cooler, it was never allowed to hit 68C. It doesn't seem to be time based. I could run wPrime's stability test and it never dropped in multipliers.

It seems to be temperature based. I'll try Prime 95 with Thermal Monitor disabled to check for this.

Any thoughts?

--Edit--
I turned off Thermal Monitor and ran Prime at 3.6Ghz. I'm still getting the multiplier drop, but now CPU-Z and the Rivatuner Monitoring Graphs don't recognize the drop and they say the CPU is at 3.6Ghz.

The temperatures would throttle back even with Speedstep, Thermal Monitor, and that other one thing disabled. The two hotter cores would throttle back and the idle pair of cores would still be the same temperature.

Since CPU-Z didn't recognize the multiplier drop, I quickly switched to wPrime and used the 32M speed test when the temps throttled back. I ended up getting 18 seconds on the test which is what I get at 2.4Ghz instead of the normal 12 seconds at 3.6Ghz.

I've come to the conclusion that the problem is caused by heat or a weird Thermal Monitor glitch, but that would make no sense since my TRUE is cooling the CPU much better than the ASUS cooler I had. The ASUS cooler caused the multiplier problem at a higher temperature than the "limit" on temps now with the TRUE.

It's still the same thing since the first post.....

I still have the problem, even with Thermal Monitor disabled in the BIOS.

CPU-Z no longer picks up the multiplier drop when the hottest cores reach 62C and the temps/multiplier throttles back.

What is causing this? How do I fix this problem?
