I recently became an owner of MB Huanan x79 (actually there is a c602 chip) and e5-1650 CPU.
I was able to overclock it to 4.2GHz without any problems. But the processor is throttling to 3.8-3.9 GHz in the LinX 0.6.5 test.
Power Limits in BIOS are set to 255.
I noticed that in the ThrottleStop soft in the TPL section there was a parameter PP0 Current Limit with a value of 185.
And IA Cores Power just reaches 180 Watt during the test.
I tried to increase this value in the PP0 Power Limit line but this did not bring any effect. If I set the value at least 5 units less (180) then the CPU starts to work unstable.
What could be the problem?
And another question, is this the normal voltage for such frequency?
As far as I know, the E5-1650 Version one can only be OC to about 3.8-3.9Ghz. This is probably why you're having issues.
Hi. I'm new here and my OC background is unusual in that I only overclock locked BIOS Dell computers using unlocked CPUs and Throttlestop software.
Fisrt I would like to clarify something in the guidlines section. The unlocked X58 LGA1366 CPUs are the W3570,W3580 Nehalem based 4c/8t 45nm CPUs, and the W3680,W3690 6c/12t 32nm CPUs. the rest are locked. The LGA775 Dell T3400, and the LGA1366 T3500 are known sytems for this. The EVGA Classified SR2 is the only unlocked 2QPI LGA1366MB and can overclock a dual CPU setup. So much for X58.

Intel Xeon E5-2630 v2
Intel Xeon E5-2620 v2

Okay out of these which unlocked or bclk overclockable? if u could reply with ul or bclk next to them would be great help.
