[Guru 3D] Phenom II 965 BE revision C3 (18 Pg.review ) - Overclock.net

AMD today is updating their most high-end processor to a new revision, the Phenom II X4 965 BE processor with stepping C3 -- and this new model is all about energy efficiency.

This processor has the same high clock frequency as its predecessor, yes... 3400 MHz. By releasing the 965BE, AMD brings their flagship processor to the table and as such, AMD has definitely earned their stripes with Phenom II.

Now as you guys know all too well, typically new revisions bring along very small subtle changes and corrections, however in the case of the C3 Phenom II X4 965 BE AMD definitely changed a thing or two in order to make their best processor even better.

This new SKU can be found located under product code HDZ965FBK4DGM, with the M indicating the new C3 revision.

The revised Phenom II X4 965 BE processor has not only a much better TDP (peak Wattage at 125W coming down from 140W) but overall much better power management thanks to the fact that hardware C1E is now implemented in the CPU, allowing the processor to throttle down. And that makes it an interesting change as it does allow for faster switching of power states, making it more efficient. Typically with such a feature enforced it could mean lower performance a little, but... with a proper BIOS AMD claims there's no real impact on performance -- and after testing it we concur.

Another, and thus third change, is what AMD calls “Heavy” load support for DDR3-1333. With proper BIOS implementation, the memory controller will now support up to 4x DDR3 DIMMs at 1333MHz which apparently was an issue on the last revision.

Check it out:

Here's an overclock at 4 GHz 100% stable. We boosted Voltage towards 1.55 in the BIOS and simply applied a multiplier of 20. Temperatures are now on the high side for an AMD Phenom II processor, but nothing to worry about at 61 Degrees
C / 140 F. Again, and I can't stress this enough -- we are only using a 25 USD air based Vendetta cooler here.

Looks like my 965 will be for sale soon

so when is this baby coming out?

3.4GHz to 4GHz is not really a big overclock in my opinion

Many people here had overclocked i7 920 from 2.66GHz to 4GHz and thats much bigger overclock

So it matters how low a company clocks their chip?

You still need 1.5V at 4Ghz to keep it stable? I thought these new revisions needed less voltages.

these chips scale really well with lower temps, i'm sure if he kept the temps lower, he'd need less voltage.

The silicon that these chips are made on are subject to better yields and reduced thermal leakage, which leads to greater conductivity and reduced thermal output. All consistent with this review. The old 965 had trouble getting to 4.0ghz stable at all, none the less at 1.512v. This is quite in the safe zone for a phenom II.

i want!

i wonder how well it will oc?

Well they show how well it overclocks lol

me want too

Jeez, now I want one of these.

When're AMD going to nudge up another notch with a 975?
