Xeon Quad Core on socket 775 seems more efficient than C2Q.
I've been laughing at the Kenty's power consumption. Maybe I was wrong?
The chip isn't on phase change but is water cooled. So no sub zero temps.

Shens!
It's probably fake, or the cpu-z isn't reading the correct voltage. Anandtech got their QX6700 to run 3.2Ghz at stock voltage 1.35v and 3.46ghz at 1.385v. Xbitlabs got their QX6700 to run at 3.5Ghz at 1.5v.
I really don't trust those pictures.
edit:
yeah, the cpu-z is giving incorrect readings. The link had the following numbers:
3.6GHz (400x9) / DDR-1000 (4:5)
BIOS VID: 1.575v
Idle Vcore: 1.53v
Full load Vcore: 1.46v
Temperatures:
Ambient: 23C
Idle: 40C
Full load (4xPrime95): 78C
Still those temps are pretty high imo. They are probably done on high perf water cooling on open air and high speed fan(s).
OP: Rename the topic, it's misleading. The vcore isn't correct in the cpu-z and the 4ghz wasn't stable.

4Ghz at 1.15v? No way...Shining Arcanine wrote:From what I have been reading, Intel lowered the operating voltages on their Quad Core Xeons in comparison to their Quad Core 2 processors, so the 1.150 voltage is probably accurate. The new revision probably explains how it can operate at such a high clock speed at such a low voltage.

I was referring to the stock clocks, although I do not find the Xeon 3220 operating at 4GHz frequency with a 1.15 voltage hard to believe, as Intel has dramatically improved the Core 2 Duo chips with each revision and Freecableguy has such a reputation at XtremeSystems.org that I find it hard to believe that he would photoshop a screenshot.Erssa wrote:4Ghz at 1.15v?

Edit: The first edit was for a spelling correction; the second was to add this note.
