8rda+ rev 2.1 highest FSB

[overrun]

what is the highest FSB you guys can hit with rev2.1?

i can't pass 210/210 FSB... once i reach windows xp's desktop it gives me a blue screen!

here's my specs:
8rda+ rev2.1 @ (416 FSB)
athlonxp tbred b dl3tc 1800+ (11x 208)
volcano 9 w/ ductmod
512 Geil DDR400 w/ramsinks (2x 256)
GeforceFX 5600 128mb w/ iceberq4 pro
80Gig Maxtor Diamondmaxplus 9
HEC 475watts
leadtek winfast 2000xp
cyber cdrw
liteon dvdrom
6 case fans

im using the bios that came with the board.... any suggestions??

Have you tried relaxing your memory timings, add some voltage to the memory, up the Vdd chipset voltage? Next try some different memory, or test each stick you have in single channel?

already did. tried increasing voltages... running my mem on relaxed timings, and trying single channel. still, i cant reach 210/210 fsb...

it might be that i've already reached the max of my cpu. its an athlon xp 1800+ dlt3c jiuhb or it could be the bios.. im not sure.

Lower your multiplier to 10 or 10.5

Which Bios are you using? Have you tried others. Have you tried setting CPU interface to Aggressive? It may improve overclockability..It does on mine.

Its mostly likely your memory. Try running it ASYNC to weed out that possibility. If you find that you can hit a higher FSB..then you've found your problem. This could be what's causing the blue screens.



Temporarily remove your winfast card. Or uninstall it's drivers. They seem to act up at high sync'd fsb. They ALSO may or may not be the cause of the blue screens. Download the updated ones from the leadtek.



good luck.

i'll try that and see what happens.. thanks!

i'll post the results here..

Yes .. i had this problem .. i could OC my FSB to 220 but my score was very slow .. for what it was running at.

once i found out that it was my leadtek drivers on my TV card .. i stoped it from loading upon windows start .. and i went up in sandra from 2843 to 3345.

try your vcore at 1.7 and your dimm at 2.77 relax your timming .. start at 200 and move up .. make sure you keep your multiplyer low and raise it when you hit the max

wow, thats true, after i disable WFWIZ on startup, my sisandra mem benchmarks went up from 2855 to 3164! thanks for that tip!

i cant seem to lower my multiplier to 10.5 and below, i can only lower it down to 11, anything lower than than, i get a 100/100fsb after reboot. and when i select higher than 12, like 12.5 it does the same, it reboots at 100/100fsb. hmmm? what'ya think?

Try updating the bios to the Aug 2003 version. It fixed the July version that limited the multiplier options.
Good Luck!!

tried it.. got the latest bios installed.

its still the same, maybe its my cpu... is that posible that my cpu only allows 3 multipliers, 11, 11.5 (default), 12

or this is a problem of rev2.1 boards.. having limited multipliers..

personally, i think its my proc...

I have a rev2.0 of the same board that boots at 100fsb at multipliers of 10 or 10.5 but does work higher or lower than this.
have you tried lower multipliers than this as mine starts working again when you get to even lower multipliers (i think about 9.5)
your cpu should be able to handle more than 3 different multipliers.
