Mobo Temps and CPU VTT Options

should say QPI/DRAM also stupid EVGA boards and the + voltage on QPI. lol your old board the base was 1.1V if I remember right, so 1.15v would be what is was at. but remember voltages will have different needs with different mobo's and different CPU's.

1.2 should be all you need, 1.25v would be max for 1600Mhz RAM

idle temps mean nothing, load it up with prime95

Huh. Maybe I should've just let it set more. The NB now is maximg out at 67C under light gaming load, for 3 hours again.

lol, alright. so what do you think can possibly be causing my NB to be that hot? Ven X is sort of towering above half of it, and it's sitting next to my main GPU which is running at ~60C. Obviously high, but the placement isn't that good in my current setup, sort of choked by the card next to it. The NB itself though I haven't physically touched yet though, so nothing should be affected with the actual uneven coating on the heat spreader.

currently, running a 3.540Ghz overclock, DS tested it with turbo on so they reported it as 3.7 or so. I've ran Prime95 for the first time a few hours ago, which has led me to the assumption that I didn't apply thermal paste as well as I should have (or that my cooler isn't tightened down hard enough) because the processor shot up to near 100C. oddly enough, current idle temps are 40~50C though. Tomorrow I'll attempt to reapply TIM as well as checking the pressure on the cooler.

Well, sort of, I'm in the midwest but not mountain area.

agh, I'm a little farther out than that, heh.

by the way, what program exactly do you guys use to check motherboard temps? I'm getting direct readings from my motherboard's included software. just wondering if that has anything to do with my temps.

alright alright, so I'm definitely seeing the 64C here for real. well, again, any ideas on what could be causing the NB to be so hot? would there be any possibility that it's getting hot is being caused by the fact that it's surrounded on 3 corners by heat generating mediums (Killer Xeno card, Ven X, hot primary GPU)? after saturday, I'll be doing some rearranging so I can run the system without those around the NB.

EDIT :: Rearranged system a little bit so that there's less around the NB. 52C and climbing from a fresh start...

EDIT 2 :: Huh. I just did a Bing search (Bing FTW!) with the term "sabertooth high northbridge temps", and some other people are reporting NB temps in the lower 60s and high 70s under load as well. Possibly just an issue related to the Sabertooth?

EDIT 3 :: Reapplied TIM, as well as increased Ven X pressure to maximum in pressure threshhold. CPU temps are in the lower 40s. NB seems to be cooler somehow, but still above 50s.

EDIT 4 :: Noticed that I really have no airflow directly going over the NB...The Ven X sucks up the air from my side intake, while my GPUs suck up the air from the bottom 180mm fan. Pretty much barely any directed airflow is going to my NB. There's obvious dead spot in the middle of the case where there isn't a bottom intake fan, which for the CPU, that problem was bypassed by my side fan, but the NB is still getting choked. The good news is that at least there IS positive airflow in my case, since I can feel air coming out the front of my case. Still, I might consider to just swap cases maybe next year or so to alleviate the airflow issue.

EDIT 5 :: Ran a Prim95 test for about 20 min. At the rate that the NB was heating up, I would estimate that the NB would likely level out before 75C...I'll get in a full couple of hours worth of burn in later on during the month though.

yes, Vcore directly effects temp of CPU, more juice, hotter it gets. The faster you push the CPU, (increasing the power output) will increase the temps also.

sounds like you are getting there.   I like to run Linx first, it is faster testing wise, so even just 10 passes of Linx with max mem, is a good way to find the CPU V core setting, once it fails up it 2 notches of Voltage, then run a min of 20 passes, if it passes then go to 24 hours of prime95 blend test.
