OC'ing a X2 4800+

[The Borg]

Hi all,

I have been overclocking processors for a while. Nothing fancy, just a bit of a push and if it stays stable for a while, I leave it.

I have a AMD 3500+ that I managed to overclock on air (200 -> 230) quite ok. Then I upgraded to a X2 4800+. Was not thrilled that I could only get to about 228 with water cooling.

The water pump blew a while back (waiting for the replacement) so I am back on air. Have only managed to get the speed up to about 208 (4%). Yesterday I decided to try this thing of dropping the multiplier. I changed it from 12 to 11.5 and have managed to get the clock speed up to 224. With the multiplication, that give a 7% increase?

Please explain how this is possible?

Umm, no its called a multiplier for a reason. 11.5*224=2576. 12*208=2496mhz. Yes the former is faster, but strange stuff happens with memory and half dividers on AMD (It would take a page for me to explain it, plenty of threads and info using the search key). I suspect your memory is holding you back either way-personally, you are not going about this overclock the proper way, by finding the limits of your individual components. Either way, 2.73ghz (your max overclock) is a very good overclock-it just doesn't seem like it because your processor is pretty fast to begin with (2.4ghz).

Thanks for the reply. This was another experiment. I have followed the proper overclock procedure described in the main page! That is how I got the previous (water cooled) speeds. I want to try this as soon as I get my pump back.

The memory is supposed to be good, but I also suspect it is not as ggod as I thought. It is supposed to give me 1T timings, but I only get 2T.
