"New" PC keeps freezing / crashing!

[m4gicfour]

Basically it seems the 790i is notorious for hard locking if the vcore of the processor goes below a certain level... it definitely seems like a motherboard power issue -

One way to make sure that windows power management doesn't kick in is to go into vista power options>advanced settings> processor>min processor state 100%

@Mailman: Im sure he has done that already - he pretty much knows what he is doing. Also the 790i is known for this problem at stock. (read link below)

This sounds similar to the problem I had on my DFI, the chipset overheats and can't stay stable when power management lowers the volts on everything. Mine had an AMD790FX-SB600 chipset. Is 70-80C normal for a 790i?

He should be able to disable power management from BIOS aswell. I found that easier when I was troubleshooting my DFI (although my lockups were near instantaneous so it was hard to change settings in windows)

Its high, for sure, but thats under load. I have 750i and it will BSOD/hardlock above 75C - so I have to have a fan above it. At 1.5V the NB gets melting hot on these boards.

@TheMailMan78: I adjusted my voltages >because< the system kept freezing a whole lot with stock settings.

@phanbuey: I uninstalled vista I'll keep an eye on the vcore though (and adjust the gtl voltages).

@m4gicfour: I recently read that somewhere about the whole 790i series..ASUS seems to be screwing up the thermal paste of the built-in heatsink of them quite often. I'll eventually remove the heatsink to check that if the system keeps freezing with the new voltages.

aww you uninstalled Windows Fail Edition? (Windows 7 RC is the bomb)

anyways, I would do the changes that tom's recommended, and make sure that Windows was not dropping the proc voltages/frequencies at idle... last but not least - before you change thermal paste or anything - see if you can cool the NB with a fan (if you got one laying around), your problems may just go away.

If not, write Asus death threats until they send you a new motherboard worthy of that chip.

I should do the same to DFI...... Well it seems there are many issues with the 790i running at stock with every thing and you still have issues I would send the board back. There may be nothing you can do to solve the issues.

If you`re doubting on the high temps. open your side case and get an electric fan and point it directly on the mobo and set it to high speed and see what happens, just to check if it still crash

Calculating GTL ref voltages

I'm not quite sure whether I'm calculating the GTL ref voltages the right way (haven't applied them yet anyways):

NB: VTT x 0.67
CPU: VTT x 0.68

not sure about the 67%/68% either..read that somewhere on the interwebz

VTT (auto): 1.12V
VTT (new): 1.3V

NB (VTT auto): 1.12V x 0.67 = 0.7504V
NB (VTT new): 1.3V x 0.67 = 0.871V
NB (resulting GTL): 0.871V - 0.7504V = 0.1206V = 121mV

same thing for the CPU using 68%: 122mV.

Looks pretty wrong to me

Hdd or psu problems would cause freezing imo.

I doubt GTL's are your problem if it's unstable at stock. First, do what the mailman said and put everything at stock. Then do what phanbuey said and check your NB temps, try a fan. Resume OC when the problem is solved.

I've had a 680i with similar issues. The NB and SB needed extra volts to be stable and I needed active cooling to keep it cool.
