Q6600 Kentsfield @3600Mhz

Finally got an Asus P5B Deluxe for my Q6600 Kentsfield adventures and now the FSB is much improved over D975XBX Bad Axe1 board!

Seems bios sensor is out of wack, but coretemp works fine.

Seems on D975XBX Badaxe the 4 cores are registered differently from P5B Deluxe

D975XBX shows
1st cpu = cpu0 + cpu2
2nd cpu = cpu1 + cpu3

P5B Deluxe
1st cpu = cpu0 + cpu1
2nd cpu = cpu2 + cpu3

Strange the 1st core on 2nd cpu is always alot cooler!

yeah i see what you mean about the buggy temps i just thought WTF priming at 3.5GHz and only 3xC hehe

still low temps 60-66C....that CPU cooling is doing a great job that's for sure:toast:

[freecableguy]

George, I agree, your Asus CPU temperature sensor is wacked. Core temps look good though. You should be able to run quad P95/Orthos @ 3.6Ghz with about 1.575v set in BIOS (with a droop to around 1.46v!).

Try upping to the FSB to 450 and droping the multi to 8x. See if DDR-900 is faster than DDR-800 with the tighter timings on both the memory and MCH. I'd like a second data point for this...

really nice and detailled thread as always eva :toast:
nice cpu you got !

[GLENBOY]

hi eva did you try the kentsfield in your p5w dh board

[eva2000]

thanks guys :D

Haven't tried on P5W DH as it's known to have lower fsb for kentsfield

[GLENBOY]

oh right will this be the stepping the retails will be do you think coming out in january, and now you've been using a quad core what difference does it feel in real wiorld terms opposed to core duo as with 3d benchmarks it only offers a slight improvement over the core duo, thanks eva

OMG how do you get those points in HDD tests? :slobber:

btw amazing results eva :clap:

eva uses two systems

iRAM and/or 4xRaid0 SATA2 drives.......so you know how heheheh

Guys, any pencil mods for P5B Deluxe to allow higher FSB for Kentsfield ?

As far as I can go right now with unmodded P5B Deluxe due to FSB limits.

[sierra_bound]

Can you run Cinebench, eva? Where Kentsfield really shines is in the rendering department. Pi won't tell you a lot because it's a single-threaded bench. Cinebench is multi-threaded.

[eva2000]

max benchable right now is 9x400fsb = 3600Mhz

3711mhz only good for 1M right now heh

[sierra_bound]

2010 is a good score for 3.6GHz.

[Yoxxy]

hrm I had it 24/7 on P5B @ 3.9. Realized it was overheating my single stage a bit though :). Getting it fixed up that is for sure. I just left everything on auto. It seemed like over 410-420 I needed to go to 1:1 though. 4:5 had stopped working at that point even though I know my ram had more in it.

[eva2000]

Yoxxy with kentsfield or conroe/allendale ?

[eva2000]

Try upping to the FSB to 450 and droping the multi to 8x. See if DDR-900 is faster than DDR-800 with the tighter timings on both the memory and MCH. I'd like a second data point for this...

-FCG
Tried that but FSB seems limited to around 400-405FSB right now even with maxed out vfsb at 1.4v and vmch at 1.65v heh.

At >405FSB when quad benchmarks are run i.e. quad pi or stressprime it will reboot after a few seconds or minutes.

Would water cooling NB on P5B Deluxe help a higher fsb max for kentsfield without volt mods though ?

[Supertim0r]

it's weird, I can run 470fsb
IDK if its cpu or mobo limited ?

[freecableguy]

I can go as high as 488 FSB....

Cooling still remains as air on the MCH....still not sure what to think about what could be the limiting factor(s) for different board/CPU combinations.

[eva2000]

with core2 duo cpus can get 500FSB on P5B Deluxe no mods.. but core2 quad kentsfield around 400-405FSB max.

[DarkSephiroth]

with core2 duo cpus can get 500FSB on P5B Deluxe no mods.. but core2 quad kentsfield around 400-405FSB max.

Wierd, you think the board still needs a new bios or revision to fix that?

I mean Kentsfield = Core 2 Duo X 2. There aren't any major architecture differences between the two

[pentium777]

Could be the interaction between the 2xCore2s they are communicating through some bridge type of thing for lack of a more scientific explanation.

[bingo13]

You have to mod the board or have Asus send you the new revision. ;)

[ANP !!!]

In one word

A-W-E-S-O-M-E :toast:

[bofors]

Yes, this is likely the problem.

To maintain cache coherency, the two dies in a Kentsfield must use the FSB.

[Supertim0r]

You have to mod the board or have Asus send you the new revision. ;)

wich mod ? vdroop, vfsb, vmch ?

[eva2000]

yeah which mod is required for just a FSB boost ? I'd be happy to be able to get 425FSB with kentsfield right now heh

[bingo13]

It is complicated and the answer would be all of the above in the previous post. I am meeting with Asus tomorrow and hopefully will have an answer that can be explained without needing 7200 words. I do know that internally they have it running at 450FSB with several changes that will probably make it into the next board revision. At least for now the highest I have seen on the current P5B-Deluxe boards is 407FSB and it was not 24/7 stable.

If you are able, could you inquire about the 330 range fsb wall I and others seem to be hitting when OCing the QX6700 on the P5W-DH? (See my QX6700/P5W-DH/Vapochill thread). Thanx.

thanks bingo for the reply... hopefully Asus do their magic well in giving us higher FSB for kentsfield :)
