C3 stepping

post #1 of 14
Thread Starter 
Ive recently discovered that my 965 BE has C2 stepping, and therefor isn't the overclocking beast i thought it would be. My question is, how can i tell if a chip has the C3 stepping? do all the new 6core chips have C3 stepping, and if they don't how do i tell which do?

any help on this matter would be appreciated.

Download this program called CPUID and it will show which revision you have and all the other specs. I have a friend who can clock 4ghz with a c2 so I think C2 are great. C3 may just run a tad cooler.

Download cpu-z. C2 will still overclock fine they can just run a bit hotter an have weaker IMC's meaning you can't overclock your memory much if you have all 4 banks full. Not a huge problem with a BE chip that has a unlocked multi.

If you don't aleady know from the cpu part number, the easist way to download this.

Which will tell you the revision (highlighted), X6 is an E0 revision (stepping is slightly different, but thats what you mean)

If you do have a C2 stepping it will be a 140w CPU. Probably not gonna get close to the OC you wanted. I had one a while back. Have to really watch temps. Still a nice gaming chip though.

Hold on for a bit, Bulldozer's coming out in a few weeks. Either get a Bulldozer if it's good for the price, or it will push down the cost of all the the other Phenoms.

x3

The C2 955/965 although an absolute heat machine is generally good for 3.7+ GHz. I can keep 100% stable at 3.84GHz if I have 2 sticks of ram, and at 3.76GHz with 4 sticks.

I wouldn't upgrade to a C3 955/965 from a C2. Gain in speed would likely be less than 10% even if you got a good overclocker.

Absolute minimum would be a 1090T for me, and I'm hoping bulldozer sets the x6 CPUs into the bargain bin. A thuban seems to make about the same amount of heat (or maybe even less) than my C2 955. Case in point, my CPU temps are under control, but the mainboard even with its heatsinked 8+2 phases throttles itself above 3.8 GHz because per my killawatt measurements even when figuring PSU efficiency the CPU can draw north of 200W even when still under 1.50v.
