Hello guys, i want to overclock my 3960X to 5GHz even more if its possible.
Till now i'm pretty stable at 4.8GHz with 1.37V Vcore. What changes have to make to succeed or brake 5.0GHz?

This are my settings till now:

CPU Vcore:1.37V
VTT CPU Voltage: 1.100V
2nd VTTCPU: 1.05760V
CPU VCCSA:1.100V
CPU-PCIE Spread Spectum: Disable
CPU Load Line: Ulrta High
CPU Current Capability:140%
CPU Clock Gen Filter: Enable
DRAM Voltages:1.5V
CPU Fixed Frequency: 350
CPU Power Duty Cycle: Extreme
CPU Power Phase Control: Extreme
VCCSA Load Line: Extreme
VCCSA Current Capability: 140%
VCCSA Fixed Frequency: 350
PLL Voltage:1.8V
DRAM's Current Capability : 120%

I use G.Skill RipjawsZ 2133 (CL9) and my CPU is custom watercooled.

You'll need a Vreg ("VRM," "MOSFET") water block to do that.

Overclocking is useless to me if it is not rock stable.

No he won't. I have been to 5.4 on mine for some bench's and all I have on the vrm's is a 4' fan, chip on water of course.

Now all chips are different, but with it under water 5.0 should be very doable.

I am 5.0 stable with Vc at 1.475, VCCSA at 1.25, load line high, Current Cap at 180%,

Assuming by watercooled you do not mean something like an H100.

Yeah, "ignorance is bliss." Happy for you DooRules. I apologize that I just don't believe that you don't have downclocking happening. But for everyday use you prob don't.

Actually, if you were lucky enough to get such a fantastic chip that you don't have to raise Vcore significantly then you might actaully be able to do this. So, ask yourself, "do you feel lucky?"

You are of course free to believe what you choose. I was merely pointing out to the op that he can most likely achieve 5.0 without much hassle and without a block on the vrm, that's all. 🙂

As to what is stable for you and what is stable for someone else, anyone else, completely different thing. Everone has their own idea of what is stable pretty much. 😄

stable 5.0 or higher use 24/7, ahhh that is the question. :cool:

No, i dont want 5GHz for 24/7, just for some benchmarks.

One way of confirming if the VRM is overheating and throttling the CPU would be to run 10 to 20 runs of LinX and see if the Gflops are declining with subsequent runs.

Like this ??

Settings are : cpu @ 1.465v in the bios with cpu current capability at 180% , ram at 2133 and the vccsa at 2.25v

Hey hillguy, nice to see you here (instead of EVGA); it's about time somebody answered me with some real data about the Vreg issue. I haven't been able to find many ppl who are getting >4.7 and don't have a Vreg WB. But I see you have some major fan cooling on your Vreg area - ppl you should see hillguy's rig:
EVGA ModsRigs: buildID 21515 hillguy

He has a very serious awesome rig there.
Hillguy do you mind if I ask you a Q?
What version of Linpack binary are you using?
Newfie my a**. 😉
