Hi Folks,

I must confess it's been a long time I've been reading very carefully all the posts from the beginning but I never had time to post a comment myself...or maybe I was too lazy. I must thank you all for giving life to that forum everyday and it's a pity that I've heard so many people deceived by this board and giving up. I was also feeling the same many times, thinking I should not have paid the price for this board as many lower price boards can do better in matter of performances and it is a shame that Asus is not offering better services to people who has chosen the must of their products. But I'm still hoping that the bios we are all waiting for will come soon and bring all the potential of that board.
I had previously a P5K Premium which could not drive me to such FSBs than the MIIF but was more stable and faster (for example I was 10 MB/s faster on file copy)...it was based on P35 so logically P45 should have been better and it might be the case for some other boards.
According to a lot of posts, some of the bests MIIF have impressive results and what everyone agree is that it can strike violent FSB even with 4 rams. Hope there will still be people trying to reach the maximum of that Maximus...because so many available tweaking could not be just for cosmetic.
I'm happy to share a few results with you, it still can be improved (and we'll work on it), there are not so many posts about E8600 and I would like to add my contribution.
When I first got my MIIF, after long weeks of tweakin I could reach a safe 4.4 GHz at 490 of FSB pushing the RAMs to a nice 1177. I will attach some screenshots but only the Everest Memory Benchmark to save place...

I was aware that it was not enough for such a motherboard though I'm on air.
Thanks to Simps and the documentation he made I could go on again with the overclocking and I was able to reach a benchable 540 FSB but not stable at all.

Anyway it was the best result for me so far with 4 gigs of memory...I remained at 490 and forgot the overclocking for a while. I recently got me a second E8600 which was supposed to need less voltage than mine but I had a lot of instability and could only perfom 4.3 GHz max.
Fortunately I kept a profile with the 540 FSB in my second boot and a few weeks ago I decided to retry a few tweakings. I could hold a stable 520 FSB but with 8 multi which gave me only 4.16 GHz.

I was seriously thinking that my new CPU was a crap and I was getting mad, but I was hoping that my MB has changed after many months of use and needed to modify a few settings. I never thought about changing the PLL voltage because I was scared to destroy my CPU so I was stacking at 1.5 V max...I finally got some courage and tried a little more voltage staying still far from the 1.6 V max safe for that CPU...that did the trick! I could reach a stable 4.37 GHz at 515 FSB with a 8.5 multi.

I used to enter manually the voltage with my first E8600 but as it was more tricky with the new one I set it to Auto to start hostilities...at 4.4 GHz it was needing 1.38 V (in Auto) and I found it more hot than the first one at that voltage due to the small VID (1.1000)...after 2 days of stability I decided to give it less voltage and passed 1H CPUStress at 1.37 V...day after 1.36 V, 1H30 at 1.35 V and so on...my minimum voltage to get stable is 1.30 V (which is not bad after all).

What I can confirm is that adding a very few more volts on PLL helped me to decrease CPU voltage. High FSB has no real benefit for me because over 500 I need to decrease PL which means a lost in the bandwidth...when I was at 490 I was running PL 8 Stronger and now only PL 10 Moderate...a little more bandwith on Write and Copy but less on Read, a little more voltage on VNB and VFSB with a little more heat and I have the feeling that the MB is a little more noisy at high FSB.
So what's coming next? I will go on for a nice 4.5 GHz at 500 FSB with RAM 1200 and PL8/PL9 Stronger...it's a good challenge and I'm crossing fingers...sorry for the length of my post...best overclocking to all!
