My New Manual OC 3930k

[koryusai]

Hi guys,

After kilobravo suggested that i try a manual overclock not just a auto 4.4GHz one to get a better 3dmark11 p score this is what i came up with (below is what is set in the bios)

CPU = 3930k
MOBO = ASRock Extreme9 X79
Cooling = H100

BCLK = 100 MHz
Internal core pll over voltage = enabled
core voltage = 1.385V
LLC = LV5 (highest)
CPU PLL Voltage = 1.857V

What do you guys think, keep in mind this is my first manual OC. Heres a windows Screen Shot

(my 690 is overcocked +135%/+125/+555)

A few questions which one is the correct voltage(CPU-z/HWiNFO64) and what stability test should i do for my LGA 2011 3930k because i heard that prime is not the best for lots of threads on another video/forum, so far i have done:

Intel Burn Test - standard 10
3dmark 11 - performance
Folding At Home - 3 hours

Stress testing is best on F@H mate
if it isn't F@H stable, it is NOT stable at all........

and IIRC CpuZ is pretty correct al tho no idea with Vdroop.....

Thanks ray i will leave it folding for the rest of the week and monitor the temps. i tryed another intell burn test but is said it failed

That's a good first overclock IMO, but in my experience i would try to get lower voltage/core setting just because i don't like seeing temps above 70

Like on my rig i have it set at 4.4ghz @ 1.315 volts with an h100 with nf-f12s and i don't really see any temps above 65 while gaming and i've had this setting since february.

You should be able to drop your core voltage a bit. I have mine at 4.6ghz at 1.35v in bios and 1.336v in cpuz. Running a H100 as well and my temps never went above 71C on the hottest core with the fans on medium speed. So your temps should drop if you drop your voltage and in theory should be stable but then every chip is slightly different.

As for testing I used Intel burn test and ran it for 4 hours. Mine has been stable since so I would say if it can survive 4 hours of ibt then it should be stable. That said everyone will have differing opinions on that.

If CPU-z is reading 1.28v and you have it set to 1.38v with loadline calibration maxxed out thats a really shit motherboard!



^^^poster above look at the volts in CPU-Z its dropped loads!

Have to agree with tom. 1.28V after setting 1.38V with load line calibration isn't good at all. I can't blame it on the software not being up to date either since the CPU-z version is the latest version out there atm.

What I would say though is that the temps are pretty high at the moment, so if you can I would lower the voltage a bit and maybe switch off the load line calibration since it doesn't seem to be doing anything
