First have you run
Prime95 small FFTs and watched core temps with
Real Temp for at least 15min or until they stabilized? If so, what are your temps?
Did you use my guide to get to 3.2 or were you already there? At 3.2 I would probably have set things a little different to come to the same outcome, but I don't think it really matters.
Yes the RAM does use a multiplier on the FSB. The multiplier choices change based on the (G)MCH Frequency Latch. At any rate, it isn't that important.
The Core2 architecture isn't very sensitive to RAM speed. I would back the RAM speed down to 800 and tighten the timings to those found in the SPD tab in
CPU-Z for 800. The gains by running at 1066 are negligible and you increase the heat of the RAM needlessly.
Yes, the core2 does use EIST and C1E. I leave EIST disabled and use C1E. You have a misunderstanding of the purpose of C1E. It is very similar to EIST, but it doesn't put your computer to sleep.
Here is a test I did of C1E and EIST for the P35-DQ6. I believe you will find the results are the same for your mobo. I assume you have Vista. It should be similar, but you will have to make any adjustments needed.
BIOS Setting: EIST Enabled C1E Disabled
In XP you need to set Control Panel -> Power Management -> Minimal Power Requirements to enable EIST.
EIST only works with the stock frequency - no overclock.
It will adjust the multiplier and Vcore.
It will adjust only the multiplier if the Vcore is set to manual in the BIOS.
Right click My Computer and click Properties will give a current snapshot of the CPU frequency under the General Tab.
BIOS Setting: C1E Enabled EIST Disabled
No settings in XP are required.
It will work at stock frequency and overclock frequencies.
It will adjust the multiplier and Vcore at the stock frequency.
It will adjust only the multiplier [strike]if overclocked[/strike] or the Vcore is set to manual in the BIOS.
Update with latest F7 BIOS will adjust vcore if set to auto
Right click My Computer and click Properties will NOT give a current snapshot of the CPU frequency under the General Tab.
