Overclocking IV – Dual-Core E6750 at 3.50 GHz

Ad

Like we said – the G0 stepping offers a lot of overclocking potential. Our E6750 went to 3.50 GHz without much effort, once again completing our Prim95 torture test without incident.

E6750 Q6600 Overclocking

In order to achieve this overclock, we now had to tweak the core voltage a good deal more. The CPU only became stable at 3.50 GHz in Prime95 after we increased the core voltage by 0.0625 Volts to 1.41250 Volts.

Memory frequency increases further, reaching DDR2-876 at CL 4.0-4-4-12.

so what you just said, is the newer stuff is better

i dont know why they take 10 pages to show what can be said in 1 page + a few graphs

On top of that Crysis is meant to be very cpu dependant and prefers 4 cores - it's the way things are going

Hmm, if they'd have gone for a different motherboard they could have gotten the q6600 to 3.6 on air.

Dunno if you have a duff chip or mobo. I have a Q6600 and exactly the same cooler and I can do 3.41 GHz at stock voltage on a Gigabyte 965P-DS3P.

"Its stock clock speed is 2.4 GHz, which it operates at using a comparatively low core voltage of 1.3125 Volts – the lowest core voltage available for this chip"

Wrong my Q6600 is 1.26V although it runs slightly higher in practice.

I guess this shows how OC'ing can vary depending on luck. Even hand picking the best S numbers is no guarantee. A bit of luck (unless you have deep pockets) can be key.

Fortunately for myself, my Q6600 is 1.28v core, and hits 3.6GHz with only slight bump.

Indeed electron migration is a significant issue at high Vcore but realistically most of us overclocking are probably running 6-12 month cycles on our hardware (at least from my experience) and the cost of killing a mid range part every year against taking a top end part is still more cost effective.

That's given only one CPU in the past 15 that I've OC'd have failed (possibly luck?) on me and that was due to a faulty voltage regulator on my motherboard :(

Very nice review/test. Highly informative. I was gonna buy a 6850 or a quad core but now im just gonna grab the low cost msi board and a 6750 and spent my cash elsewhere.

question, you end up recommending the MSI motherboard, but the test system states that you used the gigabyte for the test. Will i be able to get the same clocking abilities with the MSI?
