Two general OC questions

[neteng1958]

I was wondering is someone could help me with these 2 questions.

1.) If there was 2 ways to reach the same exact speed using the mult and FSB is one preferred over the other.

Example: I can OC my E6400 to 2.4 Ghz two ways -

(8X mult and 300 FSB) or (6X mult and 400 FSB)

Is one way better than the other or it doesn't matter as long as they are stable.

2.) I am using PC 6400 (800) RAM. If I OC with a combination of Mult and FSB that causes the RAM to operate at a speed that is lower than the rated speed (because of the mathematical relationship of the 3) am I wasting the capabilty of the RAM given that I paid more for the higher speed RAM.

Example: With a Mult of 8X, a FSB or 333 and a mem mult of 2(1 to 1 Ratio), I think my memory will run at 667 instead of 800. (Sorry if math is wrong). Should I avoid OC settings that don't make full use of my memory's capability. I have a GA-965P-S3 and it seems like it doesn't like any other mem mult except 2.0

Thanks

1) Stability is very important in overclocking. The 400x6 would be slightly faster than the 300x8 due to the faster FSB. Everything that is tied to the FSB will gain a boost from the higher value.

2) I don't think you can "waste" the capability of your RAM. If you can't max it out now. You will later on...trust me.

Thanks for that help. As you can tell by the way I worded this I am a little new but am trying to get better.

Currently I am running my E6400 on a GA-965P-S3 at 400x7 and all stock voltage except the Vcore which I reduced from 1.35 to 1.2625. I have all info about this in the other post I put up.

That seems pretty good for a new guy. Try putting the the multiplier back to 8. If you run into stability issues, up the voltage back to stock 1.35V. That should get you from 2.8GHz to 3.2GHz. Let us know how it works out.

BTW: Welcome to the forums!!

The only thing that is is likely to stand in your way is heat. Your setup runs at 400FSB, and your chip is undervolted. Try the 8x multiplier and see how your temps are. If you're not stable at 1.262V, try bumping it up to stock like Cheex said. If it's stable there, start moving down again to find the sweet spot. Lower voltage=lower temps.
