ASUS P5W DH - Problems + Fixes Thread

[dabl]

I haven't booted the board yet, mine is 1.02g, wish me luck , going to boot it tomorrow or the day after. Have a 9550 45nm, so just waiting for the problems, if I hit 2.8 ghz and no problems, Ill be a happy camper, thats 350 fsb.

I'm very interested to hear how you do with this chip on the p5w dh and the 2901 bios, particularly with any 64 bit windows installs.

I have the same cpu related questions that you asked in this previous post

Thanks for the link in that post to the related thread at social.technet.microsoft.com, very interesting and eye opening. I had gotten the impression from the below Asus blurb that other than the limitations a
Q9550 would work fine. I sure haven't seen many success stories in these threads so far, but from what I can tell one guy with a Q9650 and one guy with a Q8600 report success with Win 7 RC 64 on a p5w dh.

Support information for 45nm CPU (from FAQ)

I’ve recently bought a Intel 45nm Yorkfield CPU Q9650. When I put it onto my P5W DH deluxe, everything is perfect, but L2 cache size shows 0 KB in BIOS. When I check it in CPU-Z, the problem persists. How do I re-solve it?

Due to chipset limitation, i975X chipset is not able to support all the features of 45nm CPU. The following is a list of the limitations:
1. VT function does not work.
2. The maximum FSB is capped at 1066MHz.
3. 0.5 CPU multiplier is not supported.
4. L2 cache size is not recognized correctly. However L2 cache is still functioning.

I'm currently running an E6600 at stock speed with bios 2801, Win 7 RC 32 bit and Vista 32 bit.

I'm interested in a quad core chip like the Q9550 or Q8400 for eventual use with 64 bit Win 7 (will start with Win 7 32 bit) but it sounds like I might be better off buying a new motherboard?
