Asus boards are CRAP! but no websites dare say it.
For example on tomshadware they said this:
From CUSL2 review in 815 roundup:
"Asus has far the best overclocking motherboard right now"
HERE: http://www6.tomshardware.com/mainboard/00q3/000906/i815-31.html#recommendations_overclocking
No mention of any probs at all, in fact it got praised.
NOW, in the recent celeron review the board used was the ASUS TUSL2 which features the exact same overclocking features in the bios as the previous CUSL2.

and this was pointed out;
From Celeron 1200 vs Duron 1100 article:
"The Celeron 1200 was overclocked to 1500 MHz without any problem at all in the test. When this happens, the FSB runs at a speed of 125 MHz, the PCI bus at 41.5 MHz and the AGP bus at 83 MHz. Sensitive components such as the GeForce 3 graphics cards can have problems with the high AGP or PCI speed."
What they dont point out is that this is due to the same "excellent overclockability" of the ASUS motherboard. As Asus neglected to allow manual adjustment of PCI and AGP dividers on this reputedly "Extremely overclockable" motherboard. So what you get is the same dividers until you reach the next official FSB speed
i.e. :
66mhz = PCI 1/2 and AGP 1:1
75mhz = PCI 1/2 and AGP 1:1
95mhz = PCI 1/2 and AGP 1:1 (you see this is a dangerous level PCI now 42mhz+)
then
100 = PCI 1/3 and AGP 2:3
.........
127 = PCI 1/3 and AGP 2:3 (again unnecessary PCI and AGP speed)
then
133 FSB onwards PCI 1/4 and AGP 1:2 as with other boards.
For anyone with a cpu not capable of reaching the next official FSB speed grade the ASUS xUSL2 series are next to USELESS for overclocking. If your 66fsb celeron made 95mhz fsb with any of these ASUS boards you would be stuck as PCI at 42+mhz wouldnt be usable and also you would be forced to run the AGP slot at 95mhz, hardly a recipe for stability.
For the celeron 1200 had an ABIT ST6 or SOYO TISU board been used, a much more stable result could have been produced as these boards support correct PCI and AGP divider settings.
NO REVIEWS EVER POINTED OUT THIS FLAW.
Buying an ASUS board: ASUS = U ASS

Mind you, ASUS do make great graphics cards. He he.
