4Ghz Core 2 Duo vs M.A.M.E. 0.120 (benchmark results)
Paul Olson:
I'm still working on the e8400 overclock. It looks stable at 3.9GHz right now. I am testing it with Intelburntest. Have any of you tried it? It jacks the temp up 10c higher than Orthos does. I am still having a cooling problem. It was maxing out at 60c with Orthos, but it hit 70c once using IBT. It is mostly at 66-67, I just saw the 70 for a few seconds. I put the Core Contact Freezer on and it helped a bit, about 8c I think. I had to use the mount from my Zalman, so that probably didn't help much. The clip was hanging up on the NB heatsink on the EP45-DS3L. This mount isn't as tight as I would like, even after I shoved a washer in there. Has anyone else tried to use this cooler on this board?

IntelBurntest is a evil peice of software, it's generally considered unsave to run it for extended periods on any overclocked CPU, my understand of how it works is make a huge number of direct command calls to the CPU it such a way to light up almost every transistor in the CPU simulateously, this is only possible because of Intels internal knowledge of their processor, in effect it runs the CPU at 120%, no normal set of operations or calculations will ever push the CPU close to what IntelBurntest does.
Mounting pressure is very important to the cooling on modern CPUs, so you really want to use the mounting clip that came with the core contact freezer.
I had a quick look at picture of the EP45-DS3L and the bracket on the CCF, I think you can gain the extra clearance required to fit the stock CCF bracket by simple turning the northbridge heatsink around on the motherboard, this will mean you can't use the first PCI-E 1x slot but there are three more on the board so I can't see it being an issue.
As you can see the heatsink fins on edge closest to the PCI-E slot is lower than the rest, so buy rotating the NB heatsink 180deg it should give you the clearance you need.

Great idea, and thanks for the advice! I am at 4GHz at the moment, and it seems stable. I would like to get the temps down, so I will definitely try your solution. I ran IBT for about 15 minutes and the temp topped out at 73c. I have been running Orthos for around 20 minutes after that, and it has only reached 62c. I will try to mount the CCF with the correct bracket, then I will run Orthos for the night. Hopefully it will still be running in the morning. My vcore is at 3.38 (I think), but it drooped all the way down to 1.296 while running IBT. CPU-z is showing 1.312 while running Orthos.

Can anyone run these tests with one of the new Atom 330 processors? I am more curious how they compare to a standard Core 2 Duo than a massively overclocked one, but any comparison would be great to see.

I don't have a Atom 330 Processor to benchmark, but from it's specs and based on other benchmarks on the web of the 330, I can tell you a Atom 330 will get thumped in MAME by even a E4300 at stock clock speeds. The Atom is a great little CPU, but it's designed for power saving and not preformace.
