Question regarding Max TDP

post #1 of 6
Thread Starter 
I have a cheap biostar a880gu3 motherboard, it has a max tdp of 125w, when I unlock my x3 to 4 cores it comes up in cpuz as 126w, should I be worrying about being 1w over my max tdp? Also should I worry about my mosfets on this board when unlocking I tried asking before but didnt really get a direct answer.

CPU-Z values are really not an accurate measurement of this, however it can be assumed correctly that your CPU is pushing 95-125W and is close to the limit.  This is an A-Series board and is not designed for overclocking, hence the use of a lower end 3+1 power phase.  You should avoid overclocking and make sure you are using the stock CPU cooler for the best result, though I don't think it would be entirely unsafe to maintain the unlock.

I have no plans of overclocking on this board, waiting till I cant get a better one. I was just wanting to get the extra core cause it did unlock on stock voltage, I was worried however if during testing the stability of that core some problems will occur with the cheap quality of this board. But why would they include the ability of ACC if i couldnt. I dont know im just worrying I guess

Also what did you mean by use my stock fan h/s for best results, are you saying I shouldnt use an aftermarket?

Most aftermarket (tower) coolers blow air to cool the CPU only.  The stock cooler blows downward towards the motherboard, so cooling all other motherboard components, the VRMs/MOSFETs inclusive.  Low end motherboards usually do not take overclocking into account.  Max TDP is rated based on operation at stock speed on the stock cooler; nothing more. To be running a cooler other than stock would be pulling away from this certification, in addition to totally removing all cooling (airflow) from the VRMs.  Where there is no airflow, heatsinks can, however, help with the heat dissipation from the particularly fragile MOSFET chips - at extra cost.

ok thanks for this info I appritiate it, so when I unlock my core the temps rise, thats why the stock fan is also bothering me, any suggestions for me there

EDIT-Is there a aftermarket cooler that will blow downward, thats same style as the factory one?

There are some larger aftermarket coolers that do blow downward and cool well.  They're quite ideal for small form factor cases, for one.  Some good examples would be the ones by Noctua, Coolermaster and Scythe (I don't know the exact model names though).
