Q6600 B3 - Asus P5K Deluxe Strap Change

Swapped over to 2x1GB Crucial Ballistix 8500 dual channel kit.

It seems for my Q6600 B3 max FSB depends on how well memory modules can handle certain settings. Why ? Because my Q6600 B3 can hit 495-500FSB alot easier with this memory than other memory I've tested. Other memory hit max FSB around 490FSB.
Also I might have found a possible strap change for Asus P5K Deluxe (maybe only noticeable with very very tight subtimings ? ) @500FSB. At 7x500FSB, memtest86+ v1.70 reported 6216MB/s bandwidth. At 7x499FSB, memtest86+ v1.70 reported 6505MB/s bandwidth!.

Super Pi v1.50 32M
7x499FSB = 13m 28.313s
7x500FSB = 13m 37.844s

Q6600 B3
7x499FSB
vs
7x500FSB

Strap change does exist it seems at 500FSB changes to lower memory bandwidth performance compared with 499FSB.

How does setFSB help when booting from 499FSB and clocking up using setFSB ?

Highest FSB
with
Q6600 B3 ES Kentsfield Quad Core

Thanks to Asus P5K Deluxe and Crucial Ballistix 8500 memory, I've achieved my highest FSB ever to date with Q6600 B3 ES Kenstfield quad core cpu @502.7FSB

Not bad for an old Q6600 B3 ES that couldn't get more than 400-425FSB on Asus P5B Deluxe, limited at 350FSB on Asus 680i Striker, limited at 345FSB on Intel D975X Bad Axe 1, and 350FSB on DFI ICFX3200 at 9x and 400FSB at 7x or 8x.

This board is moving up on my "To Buy" list along with a Q6600. Thanks for the info.

Chapstick · 06-09-07

I might give into buying this board as well. Nice work btw

Yes Eva2000, apparently the P35 chipset is much.......way better than the P965 for Quad-Cores.

Some other guy here already hit 500fsb on air AND a Q6600.

That P5K-Deluxe sure would be a nice toy to have.......too bad I'm not buying any more hardware till 2010 at least.

eva2000 · 06-10-07

thanks guys

Nasgul.. 2010... yikes...

Welcome to OCN Eva2000!

I've seen your stuff at XS and I'm glad you checked us out.

MADMAX22 · 06-10-07

Nice clocks there, that crucial looks like its doing pretty good for ya.
