Overclocking my 2700K 4.8 ghz 1.32 vcore

post #1 of 19
Thread Starter 
Got around to overclocking my 2700K today. So far testing the 47 multi with vcore set to 1.27 in bios. Cpu-z reads voltage at load as 1.272 - 1,28. Real temp says vid is 1.3511. LLC is set to ultra-high. Running prime95 now. I'm bored. lol. biggrin.gif
700

edit// Prime crashed as soon as I submitted this thread. vcore now at 1.28 and testing. smile.gif

edit again// 1.29 vcore

edit some more/// 4800mhz @ 1.31 vcore in bios, cpu-z says 1.312 - 1.32. Still testing.

looks good.. working on 4.7 myself..

once you figure out your stable voltage try using offset (disable C3/C6 reporting when you switch)..

the offset is the voltage that is needed to get you to your stable overclock voltage in addition to what the mobo gives you when your running in offset mode..

ie..
set offset to +/-0, boot, the mobo gives you 1.35v under load and you need 1.40v to be stable at your overclock..change your offset to be + 0.05v
(those values are just for demo)

offset is nice because your voltage is lower than a manual vcore when idle

Once I get a stable oc I'll setup my offset. Good advice. So far about 10 minutes of prime. I'm about to stop it and switch to the 49 multi. biggrin.gif

edit/// Testing 4900mhz @ 1.34 vcore in bios. Cpu-z says 1.344 - 1.352

edit, lots of edits//// Had to bump the vcore to 1.35 still testing. smile.gif

Ok so at 4.9 ghz I got it stable at 1.36 vcore. But the temps got up to 85c running prime. Which is way to hot for my comfort zone.

So until I go to water cooling I backed it down to 4.8 ghz and 1.32 vcore. Temps are around 78ish Celsius. Which is more manageable for the time being. So far about an hour into prime blend test. I'm going for 12+ hours! thumb.gif

Two hours into the blend test! Still going. wink.gif Vcore is bouncing between 1.328 and 1.336. Set to 1.32 in bios.

Well just a little over 6 hours of prime blend. 4800mhz @ 1.32 vcore in bios. I want to stop and play games though. smile.gif Must keep going.

Congrats! I ran my 2600K at 4.7 and it was great. I upgraded to the 3960x - but mostly just for the increased ram capacity not for lack of speed in the processor.

Enjoy!

Can I get a bios template lonnie? I'm having trouble getting my 2700k to 4.8 at a voltage I can be pretty comfy with... woes... 1.368v is what I had to get in windows for stability which seems kinda nuts, i'm using an offset of +.025? or was it +.020, can't remember. Anyways, congrats. Really digging that low vcore.

Here's what I have my settings at. I'm guessing you have an Asus motherboard.

Internal PLL - enabled
LLC - Ultra High
VRM - Manual
VRM Frequency - 350
Phase Control - Extreme
Duty Control - Extreme
CPU Current Capability - 140%
C1E - enabled
C3 Report - disabled
C6 Report - disabled
CPU Spread Spectrum - Auto

CPU Voltage 1.32 in bios (cpu-z shows 1.336 under load)
CPU Offset voltage: -0.015
PLL voltage - 1.7
VCCIO - 1.10

Everything else auto. Multi at 48 obviously. Good luck. smile.gif

Good Voltage.
AVX Processor is important to the GFlops. Try also running AVX-Linx. rolleyes.gif
