Disabling cores? - Page 6

The other 4 cores would be able to reach higher clocks if the 2 other were holding them back, since they are now just idling at 800mhz and 1.2v.
It's not as simple as that. Other things need to be taken into consideration.
Moreover, if you hear those people saying that buying a 6 core CPU to disable 2 is a waste, imagine about only virtually disabling two!

It would help overclocking, but not much. Also, performance wouldn't increase considerably, it would probably decrease in 99% of scenarios.

Again, if you want to run single or dual threaded applications, those two cores are already "disabled". You can overclock as if they were @1.2v

It makes no sense, you must be mistaken or the environmental conditions changed, you misread the sensors, something else has changed, because it simply makes no sense.

No, you can't. Windows alternates loads between cores. So two of the cores were unstable at 1.3v, while the rest were not, you would BSOD whenever Windows would apply some load on the cores.

If you had 4 golden cores able to do 1.2v, and 2 bad cores that require 1.35v for that same frequency, disabling them would help a lot.

4 cores is plenty for Windows and multitasking anyways.

Comparing my 4 good cores against having 2 of the bad cores enabled, my CPU does everything better, except benchmarks.

eh..4+1 phase power with a 6-core cpu..hmm..the vrms might be getting hot..hmmm..i wouldn't be going for 4 ghz or anything..unless you have a fire extinguisher handy..

I hit 3.9 on 1.5v vcore, which I know is way more voltage than I need, but the vrms got pretty hot, I'd say around 55-65C. It wasn't unbearable to touch, but it was pretty hot. Compared to how hot my graphics card felt at 65c, it was probably somewhere around 50 or 55c.

If you touched them at 55C-65C, you would've burned your finger. Badly. When touching metal, it feels much hotter than air because it conducts temperature better.

The problem with MSI VRMs is not the heat, but the fact that they suck ass. They might fail even at stock settings.

This may sound stupid but... How do I test each core individually? :/

yes i'd like to know as well.

is just by disabling all cores except the one u want to test and then boot up into prime?

dunno

Get in to an overclock that doesnt give you a BSOD, but still is unstable enough to fail prime95. Test all cores in Prime95 and disable the cores that fail first. After you get one down, repeat the process to get another down. Then do that for how many cores you want to disable.
