ASUS P5K Deluxe - Intel P35 Bearlake + E6600 B1 / Q6600 B3

Q6600 B3 ES - Max FSB

From above quick 8x450FSB test you can see Asus P5K Deluxe has much better Kentsfield Quad core FSB headroom. I've seen other P5K Deluxe folks with QX6700 @480-500+ FSB. So now to see what my Q6600 B3 ES can do FSB wise.

I usually start off with Systool V1.0 728 build Quad 16M Pi test (uses 1.3GB of memory - the Quad 32M test uses 2.6+ GB of memory) to test max FSB for my Q6600. If it fails it usually aborts the test or reboots the system.

With below settings max FSB was around 7x470FSB

Change CPU PLL Voltage from 1.50v to 1.60v allowed me to boot into windows 7x480FSB otherwise with 1.50v would BSOD on entering windows. Upping NB Volts from 1.4v to 1.55v allowed 7x480FSB

7x490FSB is turning out to be tricky to achieve, Quad Systool V1.0 728 build 16M Pi benchmark will reboot the system even quicker if you raise vcore from 1.4375v to 1.45v. Similar thing happened on P5B Deluxe but at 400-425FSB ceiling when vcore past a certain point reduced max stable FSB.

Q6600 @3395Mhz - 7x485FSB

Here's where I ended up for single and dual Super Pi runs at 7x485FSB 1:1 )

Q6600 B3 ES @3800Mhz - 8x475FSB

Amazing indeed with Asus P5K Deluxe, I've pushed my Q6600 to a new high - being able to run single and dual Super Pi 32M @3800Mhz - 8x475FSB !

Looks like Corsair Nautilus 500 can handle it
