GEIL Memory – An Overclocking Natural
We equipped our test systems with 2 GB of memory, with our budget set at a maximum of €65. Memory maker GEIL offers some excellent products in this price range. We finally settled on the DDR2-800 modules of the Black Dragon Edition with the designation GB22GB6400C4DC, which are sold as a 2 GB set (2 x 1 GB).
Don’t take those two red LEDs the wrong way – they aren’t meant as a warning, they’re more of a fashion statement. In our test, we were able to overclock GEIL’s modules to remarkable heights.
Although the label on the modules states an operating voltage of 2.0 Volts, we reduced the voltage to 1.95 V for our overclocking tests. Despite this reduction, our stress test tool Prime95 ran completely stably.
In our test, we were able to push the memory as high as DDR2-900 without having to change the latencies from their stock settings of CL 4.0-4-4-12 or raising the voltage above 1.95 V. Despite this high frequency, it still didn’t get warm enough to require any cooling.

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?
