Memory Tweaking
All testing thus far was performed after setting 8-8-8-24 2T timings in the BIOS. In these charts, we take the Tweaked PC settings of 3,744 MHz core speed, 2,592 MHz NB speed, and 2,016 MHz HT link speed, and test with the four different stable memory settings mentioned earlier.
There is almost no difference seen in the CPU Arithmetic test. If anything, tighter memory timings are more important than memory frequency.
Here we see the memory bandwidth given up by decreasing the memory ratio. At the 2.66 ratio, only the slightest increase in bandwidth differentiates Auto, CAS 9, our CAS 8, and the tightened CAS 7 timings.
Our two manually-set timings lead the way, but overall, little difference is seen in the 3DMark Vantage CPU score.
The scaling in World in Conflict is almost too perfect, as tightening timings results in a single fps gain in both minimum and average fps. The one noticeable difference is the drop in minimum framerates at the slower memory frequency.
Tightening memory timings on this overclocked system has no impact on 3ds Max 2009 rendering time.

Well, so far I've only talked about Intel CPUs. These CPUs are in the majority, but there are also CPUs from Cyrix, IBM and AMD. What about overclocking these? Because Cyrix, IBM, and AMD have always lagged behind Intel and its Pentium CPUs in terms...

We did try to overclock our Radeon 3850 AGP to see if we could squeeze any extra performance out of it. We were quite keen to demonstrate if the AGP 3850 could keep up with its 3870 cousin at identical clock speeds, to further examine if the AGP bus...

Last month, we reviewed the Monarch Hornet Pro with an AMD Athlon 64 FX-60 at stock speeds, with specially overclocked graphics cards from EVGA. Interestingly, we can see how the new AMD CPU overclocked plays into game performance when we compare...
What's the point of using a high-end mobo to overclock a mainstream/value cpu?
it's about how to squeeze all performance from an locked cpu .
this is a pro' article (head shot)
im a big amd fans, good stuff here, look forward to go back to amd
Good article! Too bad I killed my AMD CPU
great article, should be more like it,
and a few more gaming benches wouldnt hurt either guys!
speaking of headshots yes unreal tournament is probably the most important game to exemplify the value of overclocking and added framerates due to "headshots" and shtuff.
keep up the good work!
What's the point of using a high-end mobo to overclock a mainstream/value cpu?
Fair question; no one would likely do this IRL, but I think the point here was to see how high the locked CPU could go, so they used a premium mobo.
Paul, now that we know what this specific CPU can do, would it be useful to now put it on a more typical mainstream mobo and see what one might get from the same chip under more typical conditions?
The point would be to answer the following: if my budget just grew by $25, does it make more sense to buy a BE CPU or to get a more premium mobo?
What's the point of using a high-end mobo to overclock a mainstream/value cpu?
because value mobos vary in stability much more than premium mobos. this article was just about the CPU limit, not the mobo limit.
Tom's should do a shoot-out between an i7 920 and a 965BE that's had the multiplier taken down to 13x(2.6ghz), then both OCed to the max on the northbridge alone. I'm sure that would close the gap atleast somewhat, but I'm interested to see exactly how much. Maybe they could screw around with the HyperTransport multiplier as well, it might turn out that AMD has been shooting itself in the foot with the unlocked multiplier, when more performance would be had if they were forcing people to use the northbridge.
Good write up; but PLEASE do NOT recommend OCing via Windows. Most pro's here will tell you that same thing. BIOS > Windows for OCing.
Also how about putting this under WCing or DIce/LN2?
In the performance gains and the cpu tweaking page the graphs for world in conflict are switched.
Excellent article! Thank you for the work.
Very good article!. Ryun is right, those 2 graphs for World in Conflict are switched.
I was planning on OCing but this article has made me afraid to OC, it seems there are a lot more factors involved in this than i thought.
Really good article, in the pass I has a X2 6400+, and only can overclok 100MHz....now with the 955 I have 600MHz more that the stock frecuency....
nice article.
Amd has really improved overclockability with the dragons.
Who cares how high an AMD cpu hz will go when an i7 cpu with half the speed does more on every level.
wow great increases fom a triple core. 2.6 to 3.7 is great!
Shreder: You are a perfect example of a brainwashed sheep. Core i7 has been shown to have a definite advantage in:
Video Rendering(I don't care, maybe you do)
Synthetic Benchmarks(yawn)
Specific games that have been "optimized"(rigged) to perform better on an i7
Other than that, the advantage ranges from neglible to non-existant. Unfortunately, there are people like you who swallow every bit of the fanboy articles with cherry-picked benchmarks...
Like Shadow said, its obviously a really good cpu, for overcloking from amd,
lets see how high it can go ;D
