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!

System:

• Intel Core 2 Quad Q6600 Kentsfield QUPT B3 Step 7
• Swiftech G4 Storm/Thermochill 120.3/MCP650 + Kayl 100W Custom PSU
• Asus P5B Deluxe 0804 bios (upgraded from 0405 bios)
• 640MB Gainward Bliss 8800GTS Dual DVI with 96.89 drivers
• 2GB OCZ PC2-8000 Titanium Alpha VX2 Micron D9GKX
• 500GB Seagate 7200.10 SATAII
• Gigabyte I-RAM with 1.5GB Kingston KHX3200 Winbond BH-5
• LiteOn 165H DVD-ROM
• FDD
• 3x 120x25mm 76cfm 0.4A fans
• 1KW OCZ ProXStream 1000PXS Quad PCI-E psu

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

@2400Mhz at 1.275v bios (1.232v)

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:

Yup Swiftech G4 Storm + Thermochill 120.3 + MCP650 + Kayl custom 100W psu :)

Even faster 1:1 3600Mhz time...

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...

Thanks FCG, will try that later, just submitting a few scores to hwbot :D

:D

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

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

thanks guys :D

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

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

B3 is retail.

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

Yup what dinos said :D

can you take pictures of the actual rig?

That explains all. 35k pts :woot:

Nice and detailed as always, eva. I always look forward to your threads. :)

thanks guys.. pics come later, right now all you'll see is 3x 120x25mm fans cover the whole board so won't see much anyway heh

4:5 looks fine to me on P5B Deluxe

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.

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.

max benchable right now is 9x400fsb = 3600Mhz

3711mhz only good for 1M right now heh

2010 is a good score for 3.6GHz.

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.

Yoxxy with kentsfield or conroe/allendale ?

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 ?
