Voltage problem or not???

[PANFACE]

Hi. I have a question which may be nothing but any input or advice regarding my question, voltage and temps would be appreciated .

My C2D E6400
GIGABYTE 965P-DS3
Corsair CM2x512a-6400 800MHZ
Galaxy 7600gs card
Thermalright SI-128 Heatsink and fan
Enermax 420 watt psu

It was running fine at 345FSB 1.31V Ratio 8.00 Mem 690 1.85v
FSB/MEM Ratio 1.1. I stepped it up a bit more to 355 fsb then 365 and the system seem stable, temps are fine but now for some reason my CPU-Z core speed reading jumps between either 2920MHZ (what it should be) or 2190MHZ.

Is this just a CPU-Z error or is it trying to tell me something like more voltage needed as i approach 3gig?? :?

Help and advice always appreciated.
Thanks Panface.

Also using CORE TEMP BETA i have always had pretty constant readings of TJunction 85 and both cores at 40 but now at times the core temps slightly differ. Is this ok or are imbalanced core temps no good and what's a safe limit for the core temps 60??? :?

Some voltage advice and when to up it or reduce it would also be nice as i'm still a bit unsure on this.

Help and advice always appreciated.
Thanks Panface.

Sounds like EIST is kicking in. That's Intel's "throttling" technology that drops the CPU's multiplier to 6x, in times of low CPU usage...to save power. Nothing to worry about. 6x365=2190. GL

Ahh! of course. That makes sense. Didn't know it did that. Cheers 1Tanker.

And any idea what the relationship between Speedfan and Core temp beta readings are because thet differ quite a lot.

Core temp is better than speedfan for temps.
Use Speedfan for checking voltages.
Generally when OC'ing turn eist off but seems as though it's still working ok.
