Asus P5B Deluxe + E6600/E6700/Q6600

Decided to buy a Asus P5B Deluxe as it became apparent that the Intel Core 2 Quad Q6600 Kentsfield cpu is FSB limited on Intel D975XBX Bad Axe to around 340-350FSB. But Asus P5B Deluxe is meant to allow this Intel Core 2 Quad Q6600 Kentsfield to reach 400-460FSB

I'll be testing my Core 2 Duo cpus, E6600 and E6700 as well as the Core 2 Quad Q6600 cpu on Asus P5B Deluxe.

Here's some photos to start off with





System:
  • Intel Core 2 Quad Q6600 Kentsfield QUPT B3 Step 7
  • Intel Core 2 Duo E6700 Conroe QPGA B1 Step 5
  • Intel Core 2 Duo E6600 Conroe QPGE B1 Step 5
  • Swiftech G4 Storm/Thermochill 120.3/MCP650 + Kayl 100W Custom PSU
  • Asus P5B Deluxe 0804 bios (upgraded from 0405 bios)
  • 128MB Gainward FX5200 PCI card
  • 500GB Seagate 7200.10 SATAII
  • LiteOn 165H DVD-ROM
  • FDD
  • 1KW OCZ ProXStream 1000PXS Quad PCI-E psu
Video cards to be tested besides FX5200 PCI:
  • 2x 256MB BFG 7800GTX SLI
  • 512MB HIS X1900 Crossfire Mastercard + 512MB Gecube X1900XTX Crossfire
Memory to be tested:
  • 2GB OCZ PC2-8000 Titanium Alpha VX2 Micron D9GKX
  • 2GB & 4GB Gskill PC6400PHU2 HZ Micron D9GMH 0629 batch

Notes:
  • Freecableguy posted bios screens of idea overclocking settings for P5B Deluxe to start off with at http://www.xtremesystems.org/forums/...d.php?t=115217
  • Seems to be true what others reported, P5B Deluxe out of the box as some serious vcore droop going on under full load. For example, with E6600 QPGE B1 Step 5 cpu, set 1.275v vcore in bios = 1.232v in bios and 1.22v under load in windows. Set 1.4v vcore bios = 1.352v bios and 1.33v under load in windows. Set 1.4375v vcore in bios = 1.384v bios and 1.37v under load in windows.
  • Recovery from bad overclock isn't as smooth as with say Asus P5W DH or Intel D975XBX. 99.99% of the time, a bad overclock from bios or even from windows (clockgen), you will need to clear cmos.
  • When selecting lower cpu multipliers in bios, certain applications in windows misreport the actual FSB/multiplier values i.e. coretemp, TAT and stressprime are 3 apps I know of so far.
  • The NB Strap changes and memory timings are more complex for P5B Deluxe, seems below 400FSB 4-4-4 and 4-4-3 timings are faster than 3-3-3, but above 401FSB, 3-3-3 picks up performance like expected it seems if you read http://www.xtremesystems.org/forums/...6&postcount=28 and http://www.xtremesystems.org/forums/...d.php?t=123284

Stressprime 'Orthos' small FFTs load



E6600 @3807Mhz - 9x423FSB boot from bios

Coming from a Intel D975XBX Bad Axe rev304 with less than 0.02v vcore droop under load and Asus P5W DH vcore droop, it's rather different to experience the well known vcore droop on the Asus P5B Deluxe. Under load it's near a total of 0.09v vcore droop under load from what is set in bios! But still this Asus P5B Deluxe is sweet in managing the same stressprime stable overclock that I managed on Intel D975XBX Bad Axe rev304 of 3809Mhz at 1.465v real.

For P5B Deluxe it was 1.46v under load

Really weird behaviour going on here! Seems below 400FSB 4-4-4 and 4-4-3 timings are faster than 3-3-3 and the culprit is tRCD value, but above 401FSB, tRCD 3 (i.e. 3-3-3) picks up performance like expected it seems if you read http://www.xtremesystems.org/forums/...6&postcount=28 and http://www.xtremesystems.org/forums/...d.php?t=123284

Re: Asus P5B Deluxe + E6600/E6700/Q6600

E6600 @3906hz - 9x434FSB boot from bios

Tried 1.625v (1.544v - 1.552v) vcore but only stressprimed for just over 1 minute. So had to raise vcore to 1.6625v (1.584v bios) which droops to 1.55v under load according to Asus Probe II. Managed just over 7 minutes before failing stressprime heh

Single Super Pi 32M will be slow with straight boot from bios at 9x445FSB. But these runs are just to see what the cpu can do and not meant to be the fastest times yet. I'll work on the times later Due to vcore droop to around 1.55-1.56v, the max 32M cpu overclock is lower than that of on Asus P5W DH for this cpu. On Asus P5W DH I managed 4043Mhz at 1.66v for this E6600 cpu.

Using clockgen still with the same timings and voltages I went for a max Super Pi 1M and max CPUZ Validation overclock in same windows session. Not really tweaked for fastest times yet.

Max Super Pi 1M so far = 4104Mhz


Max CPUZ Validation = 4123Mhz


That's around 11mhz short of Asus P5W DH max 1M and 138mhz lower than max CPUZ Validation on Asus P5W DH at 1.64-1.65v vcore - about 0.06v more vcore than Asus P5B Deluxe clocks.

Re: Asus P5B Deluxe + E6600/E6700/Q6600

Async Memory Overclocking 4:5


Now to test out 4:5 cpu/memory divider on Asus P5B Deluxe. As I have read, 4:5 divider on Asus P5B Deluxe is alot harder to use and will not overclock memory as high as the max achievable on 2:3 divider. Seems part of the key is NB/vMCH voltage which needs to be raised for stability on 4:5 divider. At 400FSB 4:5 500Mhz memory from bios, I still needed to raise NB volts from 1.45v to 1.55v in order to eliminate 1000s of errors in memtest86+ v1.65's Test #4.
  • Raising NB volts to 1.55v allowed me to hit 420FSB 4:5 525mhz 4-4-4-12 at 2.45v vdimm.
  • Raising NB volts from 1.55v to 1.65v allowed me to hit 432FSB 4:5 540mhz 4-4-4-12 at 2.45v vdimm straight boot from bios.
Then I tried booting from bios at 400FSB 4:5 500mhz 4-4-4-12 at 2.45v and using clockgen to raise FSB from 400FSB to 432FSB, but at around 421FSB I got BSOD from within windows while doing Systool dual 32M Pi test. I rebooted and tried again with exact same BSOD.

So I decided to change memory timings from 4-4-4-12 to 5-4-4-12 and boot into windows at 400FSB 4:5 500mhz 5-4-4-12 at 2.45v and managed to clockgen up to only 426FSB 4:5 533mhz 5-4-4-12 at 2.45v.

The end result is 4:5 divider tests results with two configurations:
  1. Config #1 = Straight bios set boot at 9x432FSB = 3888Mhz with 4:5 memory at 540mhz 4-4-4-12 at 2.45v
  2. Config #2 = Boot from bios set at 9x400FSB = 3600Mhz with 4:5 memory at 500mhz 5-4-4-12 at 2.45v which clockgen to 9x426FSB = 3839Mhz with 4:5 memory at 533mhz 5-4-4-12 at 2.45v. Taking advantage of the faster NB strap at =<400FSB.

Re: Asus P5B Deluxe + E6600/E6700/Q6600

Yeah seems like 975x chipset boards, the 965P chipset boards have some inconsistency as to it's performance.

Strange thing has happened. I just swapped out my E6600 B1 for my Q6600 B3 Kentsfield on P5B Deluxe and now the bios temps are out of wack showing 8C to 9C bios temps for Q6600 B3 Kentsfield ??

I'm using Swiftech G4 Storm water cooling and my E6600 in bios at 2400mhz at 1.275v was 26-30C bios temp, but my Q6600 at 2400mhz at 1.275v is showing 8C ??

P5B Deluxe with 0804 bios.

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

@2400Mhz at 1.275v bios (1.232v)

Idle

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

Re: Asus P5B Deluxe + E6600/E6700/Q6600

Sweet stuff. The P5B Deluxe is one hell of a board. So tempted to get one and sell my vanilla. But first I want to throw in this ST60F I just got today and see if it makes any difference.

Eva. When you say "7x500FSB boot from bios" do you literally mean you just cranked it to 500fsb from stock or do you start at say 333 and work your way up?
