I have had my Q6600 oc'd for around 1 year.
In the last month while playing BC2 my frames will drop from 40ish to 20ish when there is a lot going on.
I found out that my pc is resetting my cpu OC from 3.0 to the stock 2.4ghz.
This happens a couple of times per week.

I don't get any bsod, freezes etc, i will just drop fps all of a sudden and then the game is laggy off an on (due to low frames) until i restart my pc and load bios where it auto resets.

(ram)
About 6 months ago i got 2x1gb 800mhz to add to my 2x4gb 1600 (all for sticks are ocz platinum) for a total of 6gb (needed for adobe products).
I had to set the ram to auto to get the pc to boot, so i have just left it there.

Do you think that the resetting of the OC is being caused by cpu voltage or a ram problem, or non of those?
I didn't increase my cpuV until today as i got 3.0ghz with stock voltage with my tunic 120 air cooler.
I went ahead and increased my cpu voltage to the next setting from 1.26260v to 1.26875v but have not had a chance to really try it out yet.

Looking forward to what your voltage trials reveal.

It's interesting that the relatively new behavior occurs a few months after you made the RAM change, but that looks like an area to explore. There may be low-level inter-dependencies when any clock/timing setting is set to Auto...perhaps even chipset level...that result in unexpected behavior.

Even though you have set the RAM timing to Auto, this function isn't 100% consistent on all boards when you mix modules with different timings. If you've not yet done so, you will want to double-check appropriate values are in fact being set at boot that are compatible with both sets of modules.

Then,

If you can determine a set of safe timings that are suitable for BOTH of the RAM sets you have installed, you might consider setting them manually instead of using "Auto" (ideally these would be the same RAM settings initially assigned at boot when you had it set to "Auto" mode). But the goal here is to eliminate the use of any and all user-controllable "Auto" settings. In other words, if possible keep the same initial RAM settings, but make it a manual configuration.


(the following assumes it's consistent and quick to produce the reported CPU down-shifting)
A separate experiment (if you've not already done it) is to verify your system still behaves the way it did in the past before you installed the 2GB of 800MHz RAM. Take the system back to the old physical (including RAM slot assignments) and BIOS Settings configuration and verify the CPU is no longer down-shifting during gameplay. When/If you've done this, what was the result?


Something to keep in mind is that some Gigabyte boards require that RAM modules be restricted to specific slots when "Overclocking". This could potentially affect what combinations of memory modules are permitted or stable. I don't know if that's the case for your specific mobo. It does however suggest some experimentation with RAM module slot assignments might be of interest, and even whether you assign them as "ganged" or "unganged".

Thanks for the good info John.

I gamed last night for about 2hrs with out incident with the higher cpu voltage. I will only change one setting at a time, then try it for a few days to make sure i track down the culprit.

At a later date i will manually set my ram in bios. I had originally set them both for what the 1600 ram was said to be set to, then just went to auto. I will need to look up the settings again.

I had done some speed tests before and after installing the 2x1gb sticks of ram for performance.Bit-tech had an article about is more ram modules better/worse, on occasion it was slightly slower. I forget what benchmarks i had used, but the speeds showed nearly identical.
I noticed no change in fps in the games that i was playing. I concluded that the upgrade was worth it as later that week i utilized over 5gb of ram while running my adobe products.

Also with Ddr2, i only have 4 slots for memory. At the moment i have them paired with the same size/speed per channel.(same sticks in same color slots). Auto is 5,5,5,15. Newegg has my 2x2 1600 rated at 5,5,5,18 but read that they need to be set to 5,5,5,15 to reach 1600.
The 2x1 800 is designed for 5,5,5,15.

what about temperatures? sounds to me that it is throttling rather then resetting

You can either be part of the problem or be part of the solution.
