The P5W DH Deluxe will most likely be retired with honors as an Asus classic. Unfortunately we cannot do much about the boot-strap issue except to try and work with it. With the price of DDR2 4GB kits such as GSkill 2x2GB DDR2-667 for $199 Newegg (CL4-4-4-12 @ 1.8 ~ 19V) this would make for a powerful Gaming system in Crossfire mode, or a great little Server with WiFi and the EZ-RAID back-up. Although reading through the Xtremesystems thread indicates some P5W DH owners have misdirected their dissatisfaction towards Asus, sadly they seem unaware Asus cannot re-design the 975X. Lest we forget this chipset was originally released in 2005 and if any company would find a work-around Asus would given the 865PE pseudo-PAT debacle. When I began this article I wasn't sure where it would lead me and I thought 400FSB was my limit on this board. To see 445FSB performance and then 460FSB + potential I can only hope those frustrated P5W DH owners will go back to the BIOS and try again.
As I stated earlier 8300MB/s is the highest I can recall overclocking any Intel system lately and while it’s not up there with the “Big Boys”, so what. Anyone can buy the most expensive hardware and then break records; I don’t recall the Art of Overclocking ever being about that. Overclocking used to be a community of DIY hobbyists whom aided one another to get more from less. What happened? I can pour LN2 over my head and proclaim to be COOL, all it costs is the price of a Dewar. Although the P5W DH is still fetching a premium price ( $199 at Newegg) the P5W DH still has much to offer and I hope this review has shown just how much. We ran our E6400 at 445FSB passing all benchmarks and this system has been running for 14-days straight at that speed Gaming, multitasking and running SETI BIONIC without incident.
