FSB speeds, multipliers and video tape

[Big G]

Just a coupla questions.

My motherboard is an Asus A7V-266 (KT266 obviously) with an Athlon 2400+ (2 Ghz - 133 x 15) and 512 meg of PC2100 RAM.

I currently run this at 134 x 16.5 giving 2.22 Ghz (or somewhere between a 2700+ and 2800+).

I'm wondering is it possible to purchase PC2700 RAM and run a multiplier of 12 and a FSB of 166 (giving a 2400+ but with DDR333 instead of DDR266)? I know it's only a KT266 chipset, but i've gone into the BIOS and the FSB goes right the way up to 227 Mhz (PCI at 57 MHz) and i can indeed set the FSB to 166.

In addition, do 333 motherboards have a different FSB to PCI ratios (as in 166/33)? because if i run a ratio of 166/42 - won't this have probs with devices on the PCI bus?

Cheers

KT333 boards allow 1/5 ratio meaning that the PCI slot still runs the intend speed of 33Mhz, a max ratio of 1/4 means you'll be pushing you PCI bus at 41.5Mhz thus a number of PCI devices might go a little wired, if not stop working all together....it tends to include onboard USB sockets etc in some cases too.

I take it you did the multiplier unlock trick on your XP?

I bought it from overclockers.co.uk - they unlock it for you.

Funny you should mention the weird USB not working Embattle, because when i up the FSB to even 135 or 136 MHz (stretching the ram anyway) my USB mouse either appears and disappears or doesn't work at all.

New mobo it is - Asus A7N8X looks attractive: the reviews have all been great. The Abit NF7-S is similar feature wise and about £30 cheaper, but the reviews haven't been nearly as good as the Asus.

Would you recommend anything apart from these two?

I prefer the the nforce2 motherboards over the VIA KT400 parts, those two are very good mobos...esp the Asus.
