Hello VOGONS,
I was just wondering. I've been ever so slowly overclocking some Socket 478 CPUs on my Asus P4C800-E Deluxe, and I've noticed with all of the Northwood and Prescott CPUs, I'm unable to go above 1.6V Vcore. I've read in a couple of older forum posts scattered throughout the web that it this was an issue with Prescotts and with the motherboard recognizing the CPU as Prescott and limiting the max setting in-BIOS to 1.6V, even though there are options for higher values, although this issue is also apparent with the highest-end Northwoods I've tested. I'm in the middle of testing my two Willamete CPUs, and they obviously consume a lot more power, so the lowest setting so far is 1.75V; don't know if Asus put in place a Vcore wall somewhere for these guys, though.
In the case of the Prescott and especially Northwood CPUs, this wall has been a bit of a pain, since I know I could push these CPUs harder if it weren't for the supposedly artificial Vcore limitation on this motherboard, as my current cooling setup (old Titan water-block fitted to a modern loop with a 280mm rad and a Corsair pump+res combo) easily keeps these CPUs cool. Apparently this issue annoyed enthusiasts of the day with the original P4C800, which prompted Asus to I guess address the issue and allow for greater Vcore settings (https://www.anandtech.com/show/1133). However, which the latest 1024.001 beta BIOS, such feature is not available, and thus a hardware Vcore mod, not to mention a Vdroop mod, is my only option.
I was wondering if anyone knew why Asus decided to limit Vcore in such a way with these boards, and also for any other P4C800-E Deluxe owners out there, were there any BIOS releases that allowed you to go over 1.6V Vcore in-BIOS? Thanks!
