965BE Multiplier's Collateral Damage?

post #1 of 9
Thread Starter 
I'm getting a Hyper212EVO, but in the meantime I nudged up the multiplier on my 965 just .5X. I did some stress tests using OCCT and Prime95 with Speedfan in the back just to crosscheck temps. After 2-3 hours in OCCT and Prime95 I never saw my CPU go over 60C on any of the Temps 1 and 2(for some reason,even before I messed with OCing anything Temp 3 was always stuck at 80C).

Everything seems to run pretty stable. The absence of the any measurable temp increase would lead me to believe that I can keep upping the multi until I become unstable or heat up. But In an earlier thread I started, I was told by NexusRed that "For starters, I don't recommend overclocking on that motherboard. It has zero cooling on the vrm's which is very important." Based on the fact that my CPU nor any of the measurable components in my computer haven't changed their temps at all, It would seem that the mobo isn't being affected either.

Does increasing the multiplier put any extra stresses on any of the parts of the mobo like the FSB?

Increasing the multi increases the clock speeds and thus increases the TDP on the chip and ultimately stresses the VRM's of your mobo. Which mobo do you have?

Put your rig in you sig so we know what you have, then your questions can be answered better. Follow the link in my signature. Multi won't affect FSB, but does change the overall frequency, which in turn produces more heat. Especially if voltage is being bumped at the same time. If someone told you you have no vrm cooling, it means the motherboard was not made to overclock. It still will, but you risk heat related damage, possibly blowing some capacitors on you motherboard. A fan blowing air directly over the Voltage Regulation Modules will help this, by how much i don't know because you don't have you rig in your sig biggrin.gif

He can mildly OC, but only advised to do so with a fan blowing on the VRMs.

If you really want to get a modest OC, get a better board...

I think the tdp of the processor only increases alot when the voltage is increased. Higher voltage increases the temperature more then increasing the speed does.

Have you already purchased the hyper 212? There are better options for the same price.

With that cpu, you're already at that motherboards Thermal Design Power limit of 125w. Without heatsinked VRM's, i wouldn't go pushing an overclock on that motherboard. At least get a fan blowing on it.
Here's a good list of amd boards, and whether or not you should overclock on them. http://www.overclock.net/t/946407/amd-motherboards-vrm-info-database/0_100

Ah, So I'm pretty much hosed there. Should I drop my multiplier back to stock and give up until I can get some better cooling for everything?

If you only increased the multiplier and not the voltage then i dont think there will be any more heated generated by the vrm's. Your cpu creates more heat if running faster but not as much as if you were increasing the voltage aswell.

If CPU voltage control is left at Auto, voltage will increase after a step or two of the multiplier. In my experience, that Hyper212EVO is not good enough for any meaningful OC like close to 4 GHz or above on that processor.
