overclocking power consumption in relation to voltage, low power phase

post #1 of 9
Thread Starter 
My question is concerning overclocking with the low power phase on the MSI 970a-G46, and the voltage the cpu is running at. I am aware of the 4+1 power phase and am not new to overclocking.

The Question i want answered is, is the overclock capability of the motherboard limited more by voltage going to the cpu or clockspeed, or is voltage directly related to how much power the cpu requires, or does clockspeed play a big part as well?

My current overclock is with he fx 6300 at 4.5GHz at 1.38 V prime 95 stable. I am wondering if I can overclock more with this motherboard, knowing heat the voltage is so low. Maybe the motherboard can only take up to a certain voltage? There is a lot of case cooling, the vrms have no temp sensor but the VRM cooler is always cold to the touch at the top, and only warm at the base near the actual VRM's. The cpu never throttles under load in the prime 95 test.
If anyone has a knowledgeable answer it will be greatly appreciated!

It's more about volts and what the mobo can handle. You will be limited on the OC and should the mobo not like any more volts you will know it with shutdowns and BSODs even though the CPU may be able to push more clockspeed. You can also monitor the heat of the mobo in the Bios but really that won't be a good indication unless you start to see extreme temps coupled with shutdowns since some mobos can take a lot more heat due to their extreme design.

Thanks for the reply! So if I overclock to 5Ghz on this 4+1 power phase board without any crashes or bsods its fine? It either can supply the power or it can't? I can get the temps of the 970 chipset, the cpu socket, and another unknown reading from hw monitor, and they never get hot so thats not an issue, i'm just worried about the vrm's.
To put this simply, an example would be that the motherboard can run a cpu at 1.45V, any more and it would crash. regardless of clockspeed?

Yes, if the mobo is not rated for a certain volts due to design it will shut down.

It is indeed all about voltage and its heat and not about the actual clocks.

The MSI G4x series of boards are the ones that ruined MSI's reputation as they are the ones that catch on fire when pushed too hard. They are not candle size flames either but burn the house down stuff. The G46 that you are using is the only one of the bunch that has thermal throttling built into it. The others simply burst into flames.

This thread has more info. The AM3+ chart at the top is what you want. Just click on MSI below it for more information. http://www.overclock.net/t/946407/amd-motherboard-vrm-information-list

Just because it has thermal throttling doesn't mean you are safe. Those boards use low quality parts that may or may not be ok. Monitor the VRM temperatures closely and let that be your guide as to how far to push it.

Thanks for the info guys! The VRM's stay pretty cool to the touch, I plan on checking the thermal pads on the vrm before continuing as well.

don't OC a 4+1 board, or you'll have something nasty happen (like what happened to me)
this happened to me recently, and if you look around you'll find it's a very common issue.

doesn't matter if all the components are top quality or if you keep it cool (keeping the vrms cooler allows them to carry more current, which is what i believe allowed more power than the 4pin could safely carry, as you can see above that's actually a bad thing)
4pin is rated for 144w, trying to push more power through it simply puts you at a massive risk of breaking things.
it's just not worth the risk of breaking it for an overclock. tempting as it may seem.
post #8 of 9
One good thing about this G46 is that it is an 8 pin power board. What happened to your 4 pin board should not happen to it.
post #9 of 9
ah, disregard my post then. my apologies. 4 vrms, not 4pin, i misread.
