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!.
