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:

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.

So had to raise vcore to 1.6625v (1.584v bios) which droops to 1.55v under load according to Asus Probe II.

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.AI Tuning: Manual CPU Frequency: 445 DRAM Frequency: DRR2-890Mhz PCI Express Frequency: 100 PCI Clock Synchronization Mode: 33.33Mhz Spread Spectrum: Disabled Memory Voltage: 2.25v CPU Vcore Voltage: 1.675v (1.592v) FSB Termination Voltage: 1.3v NB Vcore: 1.45v SB Vcore (SATA/PCIE): AUTO ICH Chipset Voltage: AUTO Memory Remap Feature: Disabled Configure DRAM Timing by SPD: Disabled DDRAM CAS# Latency: 4 DRAM RAS# to CAS# Delay: 4 DRAM RAS# Precharge: 4 DRAM RAS# Activate to Precharge: 8 DRAM Write Recovery Time: 4 DRAM TRFC: 30 DRAM TRRD: 10 Rank Write to Read Delay: 10 Read to Precharge Delay: 10 Write to Precharge Delay: 10 Static Read Control: Disabled Modify Ratio Support: Enabled Ratio CMOS Setting: 9x CIE Support: Disabled Max CPUID Value Limit: Disabled Vanderpool Technology: Disabled CPU TM function: Disabled Execute Disable Bit: Disabled PECI: Disabled click images for full screenshots  Then I tightened the timings in bios AI Tuning: Manual CPU Frequency: 445 DRAM Frequency: DRR2-890Mhz PCI Express Frequency: 100 PCI Clock Synchronization Mode: 33.33Mhz Spread Spectrum: Disabled Memory Voltage: 2.3v CPU Vcore Voltage: 1.675v (1.592v) FSB Termination Voltage: 1.3v NB Vcore: 1.55v SB Vcore (SATA/PCIE): AUTO ICH Chipset Voltage: AUTO Memory Remap Feature: Disabled Configure DRAM Timing by SPD: Disabled DDRAM CAS# Latency: 4 DRAM RAS# to CAS# Delay: 4 DRAM RAS# Precharge: 3 DRAM RAS# Activate to Precharge: 4 DRAM Write Recovery Time: 4 DRAM TRFC: 25 DRAM TRRD: 3 Rank Write to Read Delay: 10 Read to Precharge Delay: 10 Write to Precharge Delay: 10 Static Read Control: Disabled Modify Ratio Support: Enabled Ratio CMOS Setting: 9x CIE Support: Disabled Max CPUID Value Limit: Disabled Vanderpool Technology: Disabled CPU TM function: Disabled Execute Disable Bit: Disabled PECI: Disabled  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.   |

| Administrator | 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.
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:

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  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  )PCI Express Frequency: 100 PCI Clock Synchronization Mode: 33.33Mhz Spread Spectrum: Disabled CPU Vcore Voltage: 1.50 (1.432) droops to 1.464v Memory Voltage: 2.10v FSB Termination Voltage: 1.4v NB Vcore: 1.55v SB Vcore (SATA/PCIE): AUTO ICH Chipset Voltage: AUTO Memory Remap Feature: Disabled Configure DRAM Timing by SPD: Disabled DDRAM CAS# Latency: 4 DRAM RAS# to CAS# Delay: 4 DRAM RAS# Precharge: 4 DRAM RAS# Activate to Precharge: 8 DRAM Write Recovery Time: 4 DRAM TRFC: 25 DRAM TRRD: 6 Rank Write to Read Delay: 10 Read to Precharge Delay: 10 Write to Precharge Delay: 10 Static Read Control: Disabled Modify Ratio Support: Enabled Ratio CMOS Setting: 9x CIE Support: Disabled Max CPUID Value Limit: Disabled Vanderpool Technology: Disabled CPU TM function: Disabled Execute Disable Bit: Disabled PECI: Disabled Idle  Load  Seems 2nd cpu on the Q6600 with cpu2 + cpu3 run alot cooler than cpu0 + cpu1 @3600Mhz - 9x400FSB PCI Express Frequency: 100 PCI Clock Synchronization Mode: 33.33Mhz Spread Spectrum: Disabled CPU Vcore Voltage: 1.550 (1.488) Memory Voltage: 2.25v FSB Termination Voltage: 1.4v NB Vcore: 1.65v SB Vcore (SATA/PCIE): AUTO ICH Chipset Voltage: AUTO Memory Remap Feature: Disabled Configure DRAM Timing by SPD: Disabled DDRAM CAS# Latency: 3 DRAM RAS# to CAS# Delay: 4 DRAM RAS# Precharge: 3 DRAM RAS# Activate to Precharge: 4 DRAM Write Recovery Time: 4 DRAM TRFC: 25 DRAM TRRD: 6 Rank Write to Read Delay: 10 Read to Precharge Delay: 10 Write to Precharge Delay: 10 Static Read Control: Disabled Modify Ratio Support: Enabled Ratio CMOS Setting: 9x CIE Support: Disabled Max CPUID Value Limit: Disabled Vanderpool Technology: Disabled CPU TM function: Disabled Execute Disable Bit: Disabled PECI: Disabled   Quad Super Pi 32M  Revisiting 4:5 divider with Q6600 Kentsfield cpu Q6600@3600Mhz - 9x400FSB 4:5 OCZ PC2-8000 Titanium Alpha VX2 @500Mhz 4-4-4-4  Single 32M  Quad 32M  ---------------- Here's more benchmarks for Q6600 @9x400FSB = 3600Mhz 4:5 divider:

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? |
