hey guys gotz a question
i got a amd 2500+ barton
epox 8rda3i mobo
geil pc3200 golden dragon ram Cas Latency: 2.5 8-4-4 2T
2x256mb

k if i run at dual channel it works fine as 2500+ but i can't seem to overclock it to 3200+ by boostin the fsb to 200 it wouldnt work.
i can probably go up to 170 at the most.

but when i turn off dual channel...it overclocks flawlessly to 3200+ by boosting the fsb to 200

any ideas??

dual channel is holding u back from hitting 200, you can try relaxing the timing on your ram and uppin' the voltage, if not, then can't do much except to up the multiplier if you can

dual channel mode induces a higher chance of instability... i would try seeing how high you can get before it starts falling appart.... try 180mhz or something... just keep upping it till if falls appart... then bring it back down... slack the timings on your ram off a bit.. and start pushing on further... dependiing on how good of cooling you have in your rig... you could do what nuke mentioned... and up the voltage... some sticks like lots of voltage....but be carefull.. we don't want to not see you around due to melting silicon

just leave dual-channel off, and run it at 200

true.... probably will see a better result from tight timing and the 200fsb... then dual channel mode anyways... also... more overclockable...

single channel mode is better than dual??

Vampyromaniac · Apr 10, 2004, 03:15 AM

single channel at 200 fsb is def better than dual at 170

think perhaps single @ 200 is about same at dual @ 195

remember, dual-channel on Athlon XP isn't the same as on Pentium 4.
on Athlon XP, turning on dual-channel gives maybe 2 or 3 % more overall performance

wow..so basically there isnt a really a huge advantage of having dual channel

Nuke209 · Apr 10, 2004, 03:26 AM

not really.

do most of u overclockers work wit SC or DC

well it depends, if you can use dual channel without having stability problem, then do so, some have gotten like 5% increase, to some it's alot, to others, not much, if you can't use dual channel, then stick to regular, you're not gonna lose much, if not, any

I would easy up on timings. I heard that have easying up/higher timings can help with overclocks

kRaZeAzN · Apr 10, 2004, 11:58 PM

it works fine DC at regular 2500+ 333 fsb....but wont go at 200fsb DC...only 200fsb works on SC

kRaZeAzN · Apr 10, 2004, 11:59 PM

oh and what does easy up on the timings mean...what do i have to do =)

kRaZeAzN · Apr 11, 2004, 12:00 AM

right now im running it at 2500+ overclocked to 3200+ single channel running prime 95 and it its 49 degrees Celcius full load

go into bios, check your ram timing...as you stated 8-4-4-2.5, that would be it's ram timing, i dont know if you have it at that in the cmos, but you can relax it by maybe, making it 8-4-4-3, (take it slowly and figure it out) and add some more voltage to the ram, that might help

kRaZeAzN · Apr 11, 2004, 03:41 PM

tried relaxing...but comp wont boot had to reset cmos...i set 200fsb in dual channel...upped the chipset volt to 1.8 and dimm volt to 1.63 and it booted..was up for 5 mins then restarted
