To be honest the motherboard reporting 98C doesn't bother me too much. Turn off the alarm and set max CPU fan speed to 50% (I have a Scythe Infinity and am using the stock 12cm S-FLEX "F" fan) and I'm off to the races. In fact, I've managed 400*10 now, though I will try flashing to that new BIOS right about now. The only thing is my chip is an R0 stepping chip, not an M0 chip.
Check out id=934454 on That CPU-Z Validator. I don't like how high I have the voltages set, however. Anyways, will this modded BIOS work and allow me to adjust the more advanced/specific settings? I noticed them lacking before. I'm grabbing V-PC right now and the XP Mode thing from M$. I love 2-3mb/s download rates! Like 2 minutes to grab 500 megs. =)
Anyways, I'll upgrade the BIOS and report back. I'm quite happy that the IP35-E is allowing this Wolfdale to run; it saves me $75 on a new board, which is half a graphics card (I was thinking a Radeon HD 5750 or HD 5770). Funny thing is if I had $700, I MIGHT be able to fit a HD 5970 in this chassis; I measured 12.25" clearance which means that, with a file and some time, I would be able to sand off some of the plastic shroud. But I won't need to, since I don't have $700. And if I did have $700, I would NOT spend it on a single graphics card; I'd upgrade to a Core i5-750.
EDIT: 400*10.5 isn't working. Heat's not an issue but I am uncomfortable giving a wolfdale 1.55vcore. B'sides, 4GHz is fast enough I guess. I did get Intel-VT options, though, so I am happy about that.
