AMD 4800 X2 at 2.81ghz

[Pandamonia]

Hi,

ive been overclocking recently i am very new at this.

ive got my cpu to 2.81ghz on zalman 9500 air on 1.45v (234x12)

my ram is on 234mhz 2.5-3-3-7

stable in games so im happy with the stabilty, not bothered about prime.

1m pi in 30.9

6519 in 3d06

id like to get my CPU higher with the same or less volts. im at 36idle and 39 load.

any one advise on how i do this? what should i try and do?

thanks

36 idle 39 load? could you run dual sp2004 for 20min or so, and check the temperature ?
You can say you wont bother with prime, but when you want to get higher results you first need to know if this setting is absolutely stable. Game-stable (now) means that only one core is really getting stressed. Few games utilize both cores.

yea you at least need to run prime a little bit

see how much your pushing it

ok ill give it a whirl but ive done 32m pi and stuff and it aint crashed yet. this CPU is pretty solid. when it dont crash in normal use it doesnt seem to crash ever and 1mhz can make all the diff. ill run prime now.

Congrats Pandamonia, blazingly fast huh?

[Pandamonia]

yeh im pretty happy with it,

im looking at maybe using an 11 multi to get a higher HTT and using 9/10 to keep my ram at 234mhz where its nice

32m Pi is not considered stable.

Stable is 24 hrs Prime 95. I've even seen prime fail at 32 hrs...

[Pandamonia]

it wasnt stable anyway. game made it freeze up.

not sure what it was.. probly my ram bein 234mhz.

gotta work out how i get to 2.9ghz and still have my ram running near 225mhz or 230mhz on tight timings

maybe need to use a lower multi and higher FSB, whats the highest FSB i can run on this mobo?

any adivise on how to do this?

[biohead]

HTT speeds don't matter. Set the LDT multi so, that it's always around 1000mhz (like 5x200, 250x4, 333x3).

Just use a lower divider to take the RAM out of the picture. Dualprime for several hours at 2.8ghz Then try 2.9ghz, dualprime again. If it fails rather quickly, up the vcore to 1.5v (if the temps aren't too high that is, expert reads 8-10°C lower than actual). If 1.5v doesnt do the trick, go back to 1.45v and try 2,85ghz. Just find a good spot, it needs some time.
Regarding your RAM.. if you're trying 2.5-3-3-7 all the time... drop that. Use 3-4-3-8. The IC's are UCCC which means: aim for high frequency with loose timings, it's their nature. When you want to find out how your RAM clocks, drop the CPU multi to take that out of the picture. When you know how RAM and CPU clock seperately, try to get the highest CPU frequency ( = most important) and the highest RAM frequency, with or without a divider.

Stable is 24 hrs Prime 95
Ofcourse this is your opinion, would have been nice if you had said this. I agree with the other posters, you need to run prime95 for at least a little while to see if your CPU is stable when both cores get stressed and heat up.

I hope my 165 0610 dpmw does more than this..

Nice clocks btw!!!

go 4 2.9 FTW!!
