msi 790 fx-gd70 thread

I have to agree about the PWM temps and the necessity of forced cooling. Using an IR thermometer, I measured temps up to 90 degrees on the PWM chips at 3.8Ghz with an X4. I put a small fan, resting on the top of the graphics card, pointed at the NB/VRM area. The temps now don't break 50, and I was able to push to 4.1Ghz. I plugged the fan into the CPU fan port so I could set it to spin up with load. I have it set to target 40 degrees on the CPU, so as soon as there is any significant load, it kicks up the speed. The lowest speed is set to 40% so its still quiet.

There is no way anyone should be overclocking an X6 without at least some cooling towards the PWM section.

I do use APS because who likes huge power bills? Any little bit helps, I'm not a fan of wasting power if the system doesn't need it. I've always found the APS on this board to work very well and doesn't seem to affect stability at all.

The whole point is to seperate the wolves from the sheep. I would not reccomend it either but good chips aren't extremely common.

For my needs I need to know the board has a rock solid PWM. This is the best way i found to determine it.

If it survives with no cooling in prime95 with a sacrificial chip ( because this board when it nukes has always taken a chip ) then I am willing to put it under ln2 with a good chip with cooling on PWM

I just received a mail from msi tech support with a link to a beta bios that should solve the "ht sync flood error" when using a hd5970.

BIOS 1.1D4

Now the problem is, I still can´t open multiple cpu-z windows, after the 4th cpu-z window the system got unresponsive and rebooted.
But this time the error message was "Unknown BIOS error. Error code =9200"
I guess they just changed the error message but didn´t solve the problem...

So would keeping the APS off solve this problem?

I don't know, maybe the bad mosfets would have died anyway. Yesterday I installed 2x60mm fans on the pwm to prevent this, but tbh i don't want to risk the board and the chip.. maybe I should change to CH4 before I get my thuban (and something bad happens)..

MadDias: thanks for the link!
