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!

Orthos is by far the best tool for testing stability!

Then I'm fairly sure my recent crash issues came from using that bad PSU cable. The floppy isn't in use enough to destabilize things but three fans must have set things up so a sudden increase like launching a program while lots of stuff was going on left the system power-starved. One reason I stopped using it was the blue light on a fan it was powering dimmed, and only when I plugged it into the other cable did the light come back to normal. Only sheer stupidity made me give that cable another chance.

Bit even with my old settings, Orthos had no issues for hours and hours. I've only been running it for 2 hours lately since learing from my 410Mhz setting that if my RAM is unhappy I only need a few minutes to have Orthos die. I've moved the vCore up to 1.375V just for the heck of it, but I don't expect any more problems. I believe I have the best early version of E6300, one that OCs like a champ, so issues with other versions and vCore don't seem to apply. I guess.

If I see no more stability issues, I'll be gradually lowering the vCore until I'm back to Auto. Until I replace my RAM with something that can go over 410, this version of the board will be fine.

Thanks to all for the input...
