Overclocking 2600k, voltage on AUTO or manual

post #1 of 5
Thread Starter 
I've been reading some guides on OC'ing the chip and some of them leave out info or have errors.

Why do most guides either omit voltage info on the chip, or say to leave "voltage" on auto as you increase Vcore?

The voltage is going to increase with an increased Vcore and the mobo can set it to absurd high amounts and such.

When I overclocked my Phenom II x4 with unlocked multipliers 99.9% of the guides states to set voltage to manual and increase multiplier until computer fails to boot. then increase voltage incrementally to meet frequencies need.

IT seems the most logical too.

So what is everyone doing?

Setting voltage to manual will allow you to set it to a tighter setting and save power/heat. AUTO puts excess voltage through the chip, and you can get the same OC at a lower voltage with manual settings.

I used offset voltage. It gives you the ability to set the voltage as either + or - from some base level. I was actually using the - setting as I went up in multipliers for the majority of the time. But to get stable at 4.4 GHZ I had to use +.015v offset voltage. Which on cpu-z on prime95 is reporting 1.272v.

When I had 4.4GHZ on AUTO voltage it was 1.3v or higher I think. So definitely go manual.

From what I have seen most people tend use offset voltage or manual. I have yet to see Auto in my stable thread. Take a look, it has over over 240 entries of SB overclocks. Here it is, check out the spreadsheet:

Hope that helps thumb.gif

Sweet. I actually went over to the EVGA forums (blasphemy I know) but they had a sticky thread put out by an EVGA product manager regarding the p67 chipset EVGA boards and how to overclock the 2600k and what settings to enable/disable in UEFI for max performance.

Needlessly to say, I configured accordingly, and so far can get 4.3ghz at 1.205vcore.

Gonna see what else it can do, but pretty good so far, max temps hover around 65C 100% load in prime95 after 2hours was the longest I ran thus far.
I know it's nothing insane, but I feel like I have headroom to work with, I have actually 2 better H70 fans coming today and 1 front intake case fan coming also. Who knows, mabey I'll watercool, wonder what it can really do...
