AMD Phenom II X4 965 - Revision C2 vs C3 comparison

[Raiderman]

This place says its in stock??

Same here.

Please go an tell the guys that are posting Gulftown results that January is 3 months away

I modified the pic, now it's ok?

Please go tell AMD that you give a rats ass about NDA and want exclusivity. Sure they will be more than happy to hook you up next time around


They may say in stock raiderman but are pre order until nov 4th respectively.

I just double checked those sites and their respective part numbers.
It seems they have the 140w part numbers???

HDZ965FBGMBOX = 125w
HDZ965FBGIBOX = 140w ?

I was about to pull the trigger on a 140w 965, now I will wait for C3!

[M.Beier]

Such ashame that NDA isnt lifted, I hope to see such a chip very soon

Glad you looked a little deeper into it and did not accidentally order the wrong thing.

Great sugestion, thx!!!

What does that have to do with anything, there really have something to be proud about

[zalbard]

Relax, guys...

[Monstru]

I'll relax in Paris bro. Now I am pissed I have to pack my luggage once again....Bleah

[Xoulz]

Should test with 64 bit too :P that's what I'm interested in.

Yep^

Win 7 is the standard now, 64bit.

[FlanK3r]

i heard, its fixed now, about 4GHz with AIR stabil now too at x64 OS :-)

AMD's Phenom II X4 965 BE C3 Revision
For one or the other reason, AMD's current desktop flagship CPU, that is the Deneb core-based Phenom II X4 965 Black Edition has had some power issues. Whereas every other AMD processor is rated at or below 125W TDP, the '965 Black Edition with its unlocked multipliers for core and North Bridge has been rated at 140W, enough to raise more than one eyebrow in the evermore energy conscious world. From a misconceptual point of view, the biggest issue is that TDP does not mean that the processor will actually draw that much power, rather the TDP acronym has undergone so many permutations that it is no longer really clear what it stands for. To sync everybody back to the same page, it is the thermal design power, that is the power requirement that has to be met by the voltage regulator module and the heatsink in order to warrant save operation of the CPU under any and all conditions - as long as they are reasonable.

With the samples we had in our test labs, we never got even close to the 140W, in fact, we struggled to hit the 110W benchmark even if power was measured before the VRM which, given an efficacy in the order of 75-80% translates into maximum CPU power in the area of some 90W. It is self-understood that there have to be margins, especially when dealing with Taiwanese or Chinese motherboard manufacturers, at the same time, that 140W number has made the rounds and not helped AMD's reputation for power efficiency.

Reason enough to introduce a new revision of the Phenom II with a few small but nonetheless important differences under the metal layers .....

nice article.

The performance hit of the CnQ didn't showed. We need some benchs about that.

Article pulled? NDA is November 5th IIRC.

Just have to log in it seems.

nop it's 4th
and yeah C3 is Prime stable @ 4GHz under 64bit Win7 with voltage below 1.5V, and under heat pipe air cooling

impressive!!
would like to know if their Phenom II x3 has got anything based on C3 stepping or not

[ajaidev]

I am a new member of lostcircuits :P

seems that the C3 is really something hope the 6 core is also based on this or C4 hehehe

The OC was very impressive indeed 4Ghz with full on HTT and ability to reach 3000Ghz on NB is impressive to say the least. With C2 955 it was hard to reach 2800 NB. The thing about the voltage is a bit off tough 1.5v for 4Ghz is not that good IMO, the 955 C2 need more or less the same volts to reach 4ghz mark.

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

Many people here have overclocked 920 from 2.66GHz to 4GHz or even more, and that much better overclock than 3.4GHz to 4GHz

+1 most 920 do are sat at 4.2-4.4 got mine at 4.2

[madcho]

with very low change of vcore only ?

[dcg]

Nice job, matose! Never thought this processor will be available in Romania for testing so soon.

The ceiling on the Ph2 was around 3.8ghz-4.0ghz with good air cooling under a 32bit OS. People were simply taking their lowly stock clocked CPU and pushing it to the limit, it just so happens that the 965 is 3.4ghz stock and the ceiling happens to between a 400-600mhz increase form there instead of a 1ghz-1.2ghz increase from a lower clocked Ph2.

This also applies to the i7 and pretty much every other CPU architecture to date. Why do you think chips like the 3200/3700+, Opty 165, X2 3800, E6600 and Q6600 were so popular? They were the lowest clocked CPU's in a series and they were able to overclock to meet or exceed their flagship brethren because of the headroom available at a much much lower price.
