Because his CPU has a different VID than yours. When you use Offset, you add Volts to the VID. The VID will also change with CPU speed. The LLC setting/Level of LLC will also play a big role here.

So If I assume you both were running at the same LLC mode, your CPU have a lower VID than his, since you needed to add Offset while he needed to decrease Offset to get to the same Vcore. Indicating that you may have a better overclocker VS his.

Loose guesstimate of about 30+ fps in WoW, Org 5-6pm, 10-15+ fps in rift.


5 Blk seemed like such a minimal increase vs it's stock 100.

Wasn't trying to sound as tho the gains were astronomical, just a bit more than I had expected, which wasn't much, given that I knew next to nothing about Sandy Bridge when I bought/built mine.

Thanks for the reply. I have LLC on auto I think....I don't recall changing anything there. It just struck me as odd that there was such a difference in settings to achieve the same speed and for the voltages to be that much different.

I haven't done very much tinkering with this chip as it just seems to want to fly on it's own. I did push my Q9650 and my i5 760 pretty hard. This one .....I am treating pretty well as the highest I have clocked it is just over 4.5 for a CPUZ validation and I pretty much settle on 4.2/4.3 for my 24/7 clock

Yours and his LLC needs to be at the same Level, when at the same CPU speed to see the real difference. And when using Offset, as I've said, VID will differentiate them.

4.6 @ 1.38 & 5.0 @ 1.40

I drop down to 4.6 on the warmer days.

2600K

Mugen 2 push/pull : 4.5 ghz on auto voltage (1.3ish) & auto everything, ~65 to 70 load temps

Custom Watercooling loop : 5.0 ghz on 1.44 & 75% LLC/extreme VRM and so on, ~70 load temps (~25c water)

(Mugen 2 could go 4.7/4.8 with lots of tweaking I guess, water can do more as well I suppose )

I run 4.5GHz 24/7 but I am temp limited. Don't want to go over 75C and I'm hitting 73C now with IBT. I can't help out with the sandy-stable club because I don't like Prime95....

Quit using IBT and use Prime 95 instead. Then you won't have a temp problem. Besides, Prime 95 Blend is the supreme stability test for Sandybridge. IBT is mostly good for heating the CPU up to insane levels, and not so good for stability testing.

Intel developed the script which IBT and LinX is using, to check the thermal capability of their CPU's.

In my opinion, it is overkill and not a good stability test.
