Asus Rampage Extreme: having fun with MCH, Spi under Air and Cascade coolings

Well... First of all, nothing about breaking records here. (humm, aiming for WR is a kind of escape ahead, virtually trying to get it showning one's ability... but it obviously can't. Don't get me wrong, I eventually broke records and it was fun, moreover I've much respect for record breakers, but I feel very unconfortable with the utopic idea -and the replies such as 'great skills', etc.- that the more the WRs you achieve, the more you are great; I mean personally or even more precisely, cognitively... Ratiocinated, it doesn't make of piece of sense... or well, okay just one piece lol : )

I've recieved this board at the end of previous week. I was amazed by its layout... Then, I've quickly dived into MCHBAR as I'm used to, and, of course, I've played with my favorite benchmark... Spi lol Not to get really fast times but just to assess offset changes. (Spi to too vulnerable, I mean, too fakable... and competing for faster times is unfair because of the minority of those boring clockgen'ers whom don't get a clue neither about OS nor MCH registers tuning -apart from memset-... Very sad.)

Please excuse me for disorder... I fact, I didn't really arrange the screenies, and just ramdonly took them for upload. Many of them are showing language machine coding for some memory controller hub registers. I've prefered not to talk about them here but if some of you really want to know (not just to ask "give me the tweaks" without any sort of understanding), I would be happy to reply. Basically, I've played with some offsets of memory sizing register, and others such as tWTR, tRTR, tRTP, RDPA from channel timings registers (those already edited when using memset). I've never used copy-waza or so-called OS tweaks (instead of LSC set to 1... of course).

I've to spend more time under cascade. I've modded a BIOS (microcode 067Ah) for Spi 1M and I'm considering giving it a try at decent high clocks. BTW although actual E8600 really rocks, it cold-boots at about -80C which makes each reboot very boring.
