stuck at 13.5 and 175 fsb

[civic91dx]

im trying to iver clock my 2700+ cpu but i cant get pass 13.5x at 175 fsb. my mb is an asus a7v8x deluxe with on stick of 512mb pc 3200 kingston at 2-2-2-8. i try changin the voltage but nothin. i just got a new heat sink skl-900u runing now at around 37c. any help
thanks

Try 14x168 as a new starting place and then raise the fsb from there.

Actually you may have found the max on the chip. Not a bad clock at all.:t

well i was able to take it to 14x at 171fsb. how can i reach the limit is there a way to pass that limit?
thanks

I wouldn't say that exactly, it would probably get a higher FSB on an nForce2 board.

I dunno without VDD mods on the older revision Nforce boards 180x13 seems to be a rough limitation, i know i cant get mine past 177x13 stable, no matter how much juice i give it, and i dont wanna start VDD modding

i do agree with teddy, nforce2 would be different story.

Yeah my 1700+ is greatly happy at 200FSB although I havent really played multis yet cos I need to get some chipset cooling on there.

as an aside, teddy, pick up the Vantec Iceberq Copper chipset cooler, costs about 12 quid and when i put it on my NB my cpu now runs at 2.3ghz at the same temps it was running at 2.15ghz with the stock cooler - nice :D

I intend to jakk.:t
Dint know how much differance it would make but that sounds like its well worth it.

Try running a Alpha PEP 66t on your North bridge like I have- it just barely fits:r :r . My KX7 with only 333 chipset is stable at 187bus with Mushkin 3200 222 two sticks of 256mbwith copper black heatspreaders.:r

Heatspreders aint much when talkign in terms of o/c'ing, at best they do nothing but look different, at worst they increase the heat of the RAM. As for the original post have you tried relaxing the timings back to say 2.5-3-3-8 and upping the Vdimm voltage a notch along with the Vcore
