Overclocking with a a8n-sli premium

try the 333 setting and you should be able to get 2.5.

Hey there. Follow this link

It will help you to determine what fsb you need to run your proc at and what divider you need to use to get the desired effect in terms of overclocking. I too have the A8N-SLI Premium mobo. I have good enough memory where I can run 1:1. Currently I have an AMD 64 4000+ running at 2.736 (12x228) and my memory running at 456 (228x2). That link should help you get in the right direction

Those would be your dividers. Also, what kind of RAM do you have and how fast is it?

OK I just read up and saw you have 400 Mhz. The point of dividers in memory is so that you can overclock your processor without overclocking your memory, but getting it as close to the original 400 MHz value as you can. Your best option would be to use the multiplier of 11 (yours doesn't go above 11 right?), an FSB of 227 and set the memory to 333. Set your hypertrans port to 4 (instead of 5). However, based on your picture, it looks as though your settings are what I told you to put them at. Your memory is running at about 350 Mhz instead of 400 (so your memory is running slower with this particular overclock than it might if you were running it without an over clock. You could always try running the memory 1:1 with the processor. I'm sure you can find some forums that will tell you how fast your memory can go. At 227x11 = 2497 (or something) and your memory would be running at 227x2 (since it's DDR) which would be 454. You would also want to set your HTT to 4 instead of 5 because I hear anything over 1000 is useless. At 4, it would be 227x4 which equals around 908 I believe.

That is your mem divider, set it at 333 or 266, drop your HTT down and may give the 3500+ a bit more juice - might even run at stock volts @2.5Ghz.

Had a 3500+ run @2.7Ghz on my a8n-sli premium (all dualcore now) with if I remember only a 0.125v increase.

Good luck with yours.

Nice, tho i am keeping it at 2.5 ghz as i really like the performance and its very stable.
If am right 2.5 GHz should be like a 4500+?
