AMD Build Overclocking Help

post #1 of 7
Thread Starter 
Hello guys, I have had this computer for awhile now and intend to overclock it.

I have a few questions though. What is this thing about "VRMs"? I know what they are[quick google]. But I think they just add another element to look out for in the overclocking process. My motherboard does not have cooling for my VRMs[neither does my GPU]. Do I need to get cooling for them?

if all you are wanting to do is overclock your processor you should only really need to worry about the multiplier and processor voltage since you have a black edition chip.

you did not answer his question at all.

@ op: it's recommended to have vrm cooling, but with an 8+2 phase gigabyte board (they have good quality vrms), you should be fine as long as you have good airflow and do not go crazy with voltages.

I already overclocked my GPU to the max under Catalyst. Do I need to watch out for the VRM temps or anything? I have the fan on the card running with MSI afterburner custom fan profiles.

The processor comes next, but will this increase the heat to the motherboard VRMs?

i would not worry about GPU vrms. did you increase voltage on your card (i'm not familiar with ati cards). even if you did increase it, don't worry. no one really talks about gpu vrms, just their core temps. the only card that really has vrms problems right is the GTX590.

increasing cpu vcore will push more voltage through your vrms and heat them up more. but like i said, as long as you don't go crazy, you'll be fine. most say to stay under 1.5v for 24/7 on air.

edit: i noticed you are using stock cpu cooling. if you want to go for a decent oc, it's recommended to get a better aftermarket cpu cooler. the stock cpu cooler is actually better for vrms b/c it blows air down on the board, which lets the vrms get some air flow. most aftermarket coolers are tower-like, so the board gets no air blown on it. but an aftermarket cooler should be used when oc'ing. not sure how far you can get on stock.

Whew. That was a long read. Thanks. The chart does not say whether my board is a true 8+2 phase board or a 4+1 split into channels though.

Gigabyte boards are solid?

I didn't increase voltage to my card, the catalyst control center does not allow such a feature. Sounds good, I'll just keep my gpu cool.

Actually, I plan on just bumping up the multiplier and see how far I get[Most likely 3.7 if lucky?]. Don't want to mess with the voltages which is a good thing I suppose for the VRMs

Getting the Hyper 212 + in a couple weeks. I'll see if I can get it faced so that some air gets blown on the vrms.

Thanks for all your response,
My System

Most, including high end boards are just split 4+1. As xd says:

"the components are split as if they were an 8+2 phase; this is quite close enough to the quality of a true 8+2 phase"

And yes, Gigabyte is one of the most solid brands when it comes to motherboards.

Yup, that's why there is really no talk of GPU VRMs, except the GTX590's of course.

I have the 212+. Even having it faced toward the back of the case (like I do), it's still relatively tall, so not sure how much air they would get. If worse comes to worse, you can always buy a moseft heatsink or throw a small fan blowing on the VRMs. But if you are not really playing with voltages much, I wouldn't worry.

Most 955/965's can get to around 3.7 on stock vcore. 3.8 is kind of the "wall" where they start needing a lot more voltage. just keep temps under 62C (AMD's limit), preferably 55C (they start getting unstable after that).
