Kentsfield X6700 air-cooling tests

[Shift]

Hmm I'm assuming you live near or in Silicon Valley
Amazing results, true multitasker!

Hmm I'm starting to think you work for Intel

[grimREEFER]

wow, revision B0 kentsfield
also, nice to see someone representing the p5b deluxe, my future board
respeck

[Eldonko]

Great work as always Sierra.

[Rol-Co]

nice sierra.......go go go

the corsair is running fast too on the asus board .....isn't it? dit you tried the 8000 ul's too?

Nice chip, a bit too expensive at this time , but will get one later.

[sierra_bound]

impressive results
how is the temperature ?

Idles in the 40's. Load temps in the 50's and 60's. Watercooling might be a better option for this chip.

I grew up about a mile from Intel's headquarters.

Great work as always Sierra.

Thanks. Good to hear from you again.

The board seems to like the 6400C3's better than the 8000UL's,

[Rol-Co]

did you trie'd the kentsfield on the p5w too, or don't wanna break it down for that

cinebench is the benchmark for kentsfield, highest i'm getting with the conroe is 1350
quied a diference

[sierra_bound]

No, have not used the P5W yet for Kentsfield. Will eventually give it a try. Next step is single-stage cooling.

[vanovich]

impressive cpu .youll hopefully come up at 4,2 with phase ,or more hopefully .

Nice chip Sierra

[Alphy]

I hear Kentsfield might make 2006 to compete with AMD's 4x4. Any truth to this?

Fourth Quarter in time for Xmas and Holiday shoping how nice.

Just be careful running four instances of Prime simultaneously. It will really heat up the processor.

Does it overheat to the point that comp freezes or that it burns?

[sierra_bound]

Hasn't frozen on me yet. One instance of Prime will usually fail or the system will reboot. Generally when the temp gets above 70C, Prime will fail. Core #3 seems to run a little hotter than the others and that's always the first to fail Prime.

As I mentioned earlier, Max Tcase temp is 100C.

[sierra_bound]

I decided to put the chip in my P5W DH. AndreYang was right. Maximum FSB is not as good as P5B. Only been able to reach 350. But the P5W DH BIOS I'm using (0088) allows me to use multipliers up to 20. This can be very useful with sub-zero cooling. For example, 350X12 = 4200MHz.

Try 701 or 901 they work perfectly, and omg you dont even want to touch coretemp to look at the temps as you may cry. Curiously what are your custom prime settings as I am using stress cpu are your custom settings better for stability testing?

Lastly since I am new to all these voltage settings for the P5W I have been using 1.6v mch 1.4v fsb 1.2v ich 1.45v vcore (seems to get 3.3Ghz only just) this is using 300fsb and 10/11 multy, would it be worth me selling this board and going P5B instead?

Thanks for any advice.

maybe better psu might help ?

Wow that's huge. These chips are intended to put out a lot of heat I guess huh

I use the custom setting to divide up the RAM. I usually allocate 300-400MB to each instance. This can help avoid a lot of paging.

I've tested Kentsfield briefly on P5W DH. Can get FSB only up to around 350. With the P5B, I can do 400+ FSB.

[iboomalot]

When is this CPU due to release ???

[sierra_bound]

Official release is Q4 2006.

I think the PSU is okay. kaz-n just set WR with Kentsfield and OCZ 520W.

[TyroPyro]

60s on Tower 120 is crazy! There is no doubt about the sheer power of this chip though. Great work

[sierra_bound]

I'm not sure the P5B reads temps correctly. Core Temp readings are 10-12 degrees lower. Also, I noticed lower temp readings when using the P5W DH.

Vdroop isn't too bad under full load. About 0.05v.

Slightly off-topic CAL930 has posted mods for the P5B Deluxe. 20-50K VR's

[sierra_bound]

The 0405 bios allows for better running of 4:5 ratio on the P5B Deluxe. Though it's still not perfect.
