Hey guys
I'm currently trying to overclock my 3930K on an Asus P9x79 LE.
I'm aiming for 4.5Ghz initially.
Got the multi set to 45, 1.3V Vcore, Core current limit maxed out, got my RAM set up correctly ETC...
No heat or current limits in place (all disabled or maxed out).
CPU is watercooled.
So when I start prime95 blend everything is fine for the first test, but when the second test begins (about 5 minutes into the test) the CPU starts to throttle it's clock speed down to 3200Mhz and will fluctuate between 3.2Ghz and 4.5Ghz.
I've done some research and apparently this can happen when the motherboard VRMS overheat, so I decided to zip tie a 40mm fan to the heatsink on the VRMS and also set my 5 gentle typhoons to 3000RPM, but still I got the throttling.
I don't know of a program that monitors mobo VRMs so can't actually say if they're overheating or not.
Max CPU temp is 68C and power consumption for the CPU is 212W.
Any idea's guys?
