AMD Phenom II X4 965 C3 stepping first review!!

[CAT-THE-FIFTH]

Power consumption at both idle and load are noticeably lower:

4GHZ was also reached with some mild tweaking it seems using air cooling.

I think the article was pulled because it broke the NDA:

To sum the article up idle power consumption dropped by a third and load power consumption decreased bya round 10 watts.

Some more reviews have come out:

Improvements include lower power consumption,better overclockability and an better memory controller which can now use 4 sticks of DDR3 at 1333MHZ.

No it can't. It's still only two channels, but it can cope with 4 banks at 1333 now.

No it can't. It's still only two channels, but it can cope with 4 banks at 1333 now.

According to the firingsquad review:

“Heavy” load support for DDR3-1333: With proper BIOS implementation, memory controller will now support up to 4x DDR3 DIMMs at 1333MHz

That's 4 banks/sticks, not channels.

That's 4 banks/sticks, not channels.

OK,fair enough then.

Some reviews like toms and techreport mention only savings of 9-10 watts on load, yet others like bit-tech show around 30-40 watts difference. :/ Not very consistent!

It seems that a C3 stepping of the X4 945 is also out:

This is already a 95W processor so hopefully there will be some more idle and peak power consumption savings.

i have 4+ stable, what would you like cat?

If you can post a CPU-Z screenshot it would be good. How are the temps like and what are the voltages you used?? Stock cooler or aftermarket cooler??

[MadduckUK]

temps are 28deg idle in a warmish room, 50deg load (see speedfan), voltage is 1.46 and the cooler is a corsair H50

[MadduckUK]

just as a footnote, this is obviously the quick and dirty way to do it, ill be fiddleing with the fsb probably tomorrow as it makes quite a difference to the overall speed. im hopeful of getting a stable 4.06-4.08 kind of area without any more voltage as well, will have to see

[MadduckUK]

clever overclocking is now underway. drop the cpu in mhz, bump the NB and HT and then creep it back up using fsb. stable and faster than last night - RAM has been fiddled too, mucho bettero

actually managed to get down to 1.45v too, havent tried lower but it may go a bit

[nibbler]

Nice man. That is a hot (not literally) cpu.
