Q6600 Kentsfield @3600Mhz

**eva2000** · 11-22-2006, 05:20 AM

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)

Idle

Load

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!

@3500Mhz - 9x389FSB

To start 3500Mhz - 9x389FSB quad stressprime at 1.4000v (1.5v set in bios, 1.4720v windows idle droop to 1.4000v

Seems 2nd cpu on the Q6600 with cpu2 + cpu3 run alot cooler than cpu0 + cpu1

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

**eva2000** · 11-22-2006, 06:01 AM

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

**Supertim0r** · 11-22-2006, 11:23 AM

really nice and detailled thread as always eva

nice cpu you got !

**GLENBOY** · 11-22-2006, 11:32 AM

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

**eva2000** · 11-22-2006, 01:41 PM

thanks guys

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

**GLENBOY** · 11-22-2006, 01:42 PM

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?

btw amazing results eva

**dinos22** · 11-22-2006, 02:13 PM

eva uses two systems

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

**eva2000** · 11-22-2006, 02:19 PM

Yup what dinos said

**safan80** · 11-22-2006, 04:03 PM

can you take pictures of the actual rig?

That explains all. 35k pts

**alejo** · 11-22-2006, 05:58 PM

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

**eva2000** · 11-22-2006, 06:14 PM

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

Q6600@3600Mhz - 9x400FSB

**eva2000** · 11-23-2006, 01:16 AM

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** · 11-23-2006, 01:25 AM

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** · 11-23-2006, 01:27 AM

max benchable right now is 9x400fsb = 3600Mhz

3711mhz only good for 1M right now heh

**sierra_bound** · 11-23-2006, 02:07 AM

2010 is a good score for 3.6GHz.

**Yoxxy** · 11-23-2006, 05:48 AM

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** · 11-25-2006, 11:41 PM

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 ?
