It will be a problem if it overheat & throttling the CPU. Mine goes up to 72C @4.8GHz OC fully loaded & no sign of CPU throttling. So, no problem there. The max temp for VRM is 90C. You want to make sure it doesn't exceeds that. It all depends on the ambient, mine pretty high though. Also depends on how high Vcore you need to run at certain frequency. If you aim for 5GHz OC, it's good idea to put a 30CFM - 45CFM fan minimum for direct air flow to primary VRM heatsink assembly. This is ASUS recommendation for their X79 motherboard. And you can also put a passive heatsink on the back VRM backplate.

Aside from that, is there any reason for someone running on air cooling to use multi&bclk versus just setting the strap to 125&multi?
I mean, I was just trying it to see what I could hit, and because I wanted the voltage to drop when speedstep kicks in [which it apparently cant with a strap other than 100] but this seems to limit my OC to ~4580? I was running 4750.
I think you can get x44 multiplier with per-core
configuration. If all cores active ("by all cores"
), the max multiplier will be x43.
Don't worry when voltage don't drop down when using STRAP 125 if you have C3/C6/C7 enabled. These are C-states. CPU cores when idle, they will enter these states & the deeper the state they in, the voltage for that core also decrease. In C6, the voltage for that core is or near zero. Vcore reported by any monitoring software is not accurate
when idle. It doesn't reflect the actual CPU power consumption when idle.Edited by kizwan - 6/13/13 at 9:30pm
