First time OCing - Mobo Heat Problems!

post #1 of 9
Thread Starter 
Hey everybody, new to the forum and new to building computers. I recently just built my new rig and its been running smoothly on stock settings for a week or so now. The thing is that the mod bug has bit me and i want to OC it! Ive read and watched other sources for OCing the 1055t, but im still a little green on the subject. So enough talk here is what im running.

Processor - AMD Phenom II x6 1055t
Mobo - ASUS M4A785-M
Memory - kingston hyperX DDR2 1066

I OCed it to 3.5Ghz using these settings

CPU/HT Reference Clock (Mhz): 250
PCIE OverClocking: Manual (100)
Processor Frequency Multiplier: x 14.0
CPB Control: Disabled
CPU/NB Frequency: 8.00x
HT Link Speed: 1600Mhz
Memclock Value: 333Mhz
C1E Support: Enabled
Advanced Clock Calibration: Disabled

I ran LinX and Prime95 to stress test it, but LinX failed after 3 min... and the Mobo was at 70c according to HW Monitor, CPU was at 50c

Could the culprit be the thermal paste i put on? I removed the stock AMD one and put on Artic Silver 5. If i did not put enough or put too much on, would that cuase my mobo heat problems?

thermal paste ? not going to see a big differences in changing it
slap a fan on the mobo's northbridge

and make a heat pipe and put it on the southbridge and have it ascended to the northbridge

EDIT whats you case and its cooling set up and gpu?

First, don't forget you need to raise your voltages to get the CPU stable. Second, make sure that you have an after-market CPU cooler, and not the stock one that AMD supplied you with. Third, your Mobo has very little heatsink cooling and only has 4+1 Phase Power Design, which is a big no no for an overclocked phenom II x6 (you would want an 8+2 PPD to go high), so you cannot push your OC too high or else your motherboard will go up in flames.

wow guys thanks for the fast replies.

my first build... i knew i shoulda gotta a better mobo lol.
oh well i just got it so i'll milk it for what its worth till i upgrade later.

i only plan on having it on 3.5Ghz and i heard that should be realistic with stock cooling, although a aftermarekt cpu cooler has been tempting me. Lets see what xmas brings *evil face*

i'll try to jerryrig a fan staight to the north/south bridge

Don't go overboard on a CPU Cooler until you get a new mobo. Spending $80 on some awesome cooling isn't going to do much if your motherboard can't handle the higher OC, so I would recommend the Cooler Master Hyper 212+. It's about $20 (some places have it for less) and does a great job cooling those cpus

thanks for the recomendation. I'll look into it.

one thing though, will a cpu cooler cool down my mobo? Thats the thing im most worried about. 70c is hot. 50c for the cpu is still acceptable from what i have read.
post #7 of 9
It might a little bit, but not really. CPU Coolers are generally too high up to be hitting any part of the mobo. As for adding additional cooling to the mobo, I have little to no knowledge in that area so I can't help you out. I'm sure they sell things to cool them down; you'll just have to look for them I guess. I hope everything works out for the best!

so the best solution to the mobo problem is stick a fan to them eh? maybe replace the thermal paste of the heatsinks with artic 5?
post #9 of 9
Well like 3dfxvoodoo said above you could make your own cooling pipes. But if that is too much work then it looks like adding more fans is the way to go. I do know they sell little tiny NB and SB fans at microcenter
