ASUS P5W DH - Problems + Fixes Thread

[sesdave]

Suggested changes made. Max vMCH available was 1.65V. vICH at 1.20V.

Also fixed power-related issue, and added extra 80MM fan to left side grill. More air seems better.

vCore never seemed to matter before, and at 1.325V I still have CPU-Z telling me it's bouncing around under that anyway. Orthos now seems a waste of time to validate vCore, so what might be better?

And 2:45:00 or so into Memtest I started after the lunch crash the machine locked up, so with these new parameters and the power fix maybe an unfailed Memtest is my new stability check...

You have an early revision board which will only go to 1.65 on MCH. Most boards have a vdroop of approx .05v. Heres a link to some pencil volt mods if you want more http://sg.vr-zone.com/?i=3876 but 1.65 should be okay for upto 420-430 FSB. I run vFSb=1.3,MCH=1.65, VICH=1.2. I agree that you should up you vcore - Loosen the memory to 5,5,5,15 if you cant get stable,. If its rev 2.1 it wont clock much at all. If it is an earlier revision it will be micron D9 chips and that will fly If you up the volts to 2.2 and tighten the timmings. Disable anything in BIOS u dont recognise or use - follow this guide http://forumz.tomshardware.com/hardw...ict197995.html. Dont forget to diable any q fan control and virtulisation.
Best monitoring tool is MBM5 - I posted details recently on were to get latest vesion with coretemp plugin and how to set it up. I can send you zipped directory if you struggle. Orthos is by far the best tool for testing stability!
