BIOS updates wreak havoc with Overclock settings

OK. Nobody wants to hear about my Striker Extreme 680i board anymore. It's last year's board. It had shortcomings. But I've still been pretty happy with it.

The Striker went through a spate of BIOS updates. In the early versions, you could set the VCORE to 1.5V, but the monitored result would only be 1.44. You could then set it to 1.55, but it would STILL show 1.44. So I watched the forums and waited to see how many BIOS revisions were posted over the next several months, and was satisfied initially with version 1004 when I finally purchased the motherboard. The VCORE "set vs monitored" problem had been fixed..

Since then, I've probably flashed the BIOS twice, through version 1303. Version 1303 appeared briefly at ASUS in July 07. In August, 1305 appeared, and ASUS pulled 1303 off their web-site. [This was never standard practice -- they usually leave earlier BIOS versions available for download.]

I finally decided to upgrade to version 1305. Now, I find that whereas a VCORE of 1.4188V under version 1303 would show in Everest as 1.41V, I have to set the voltage to 1.43V just to show 1.40V now under version 1305.

Put it another way -- if you compulsively over-clock your system, BIOS updates probably create a new situation requiring a whole repetition of PRIME95 testing.

P-I-T-A. To say it's a "pity" is a limp understatement.

Well, I had one strange bios problem. I went from F7 to F9 on my DS4 board, and all of a sudden I had 3 cores on my Q6600 (in task manager). 4 cores on F7, 3 on F9 !. So I found a beta F10, and back to 4 cores.

Vdroop in most cases is just as much to do with the CPU+chipset used as it is the motherboard- Anand's QX9650 overclocking article has some good info on this.

DS4 has very low vdroop, and DQ6 has none. The DQ6 is the ONLY motherboard I have heard of that does not suffer from this.
