OK...i am unable to overclock on p5b like i was on p5w due to not being able to keep my memory near its rated speed, when ever i increase my fsb the speed options for my memory increase, so i push my fsb to 460 and the lowest i can run my memory is 900+....my memory is 800 on p5w i was able to push fsb 460 and lower my memory to 667.....so far this board isn't allowing me to oc very well....please someone tell me theres something im missing.

I don't have the highest rated performance memory. I did, but it it not perform any better than the Memory I have now (Many reviews seem to be repeated sell out information provided by the manufacture, in my opinion)Originally Posted by aledsav1
The most I could ever hit stable was, a 450 / 900 MHz. Others, have achieve greater results. They may jump in. I am just giving you may experience of my system stability.
One thing odd about my DDR2, at looser timings, it will have an overclock error. At 5-4-4-12 it is stable. And, I have 4 one MB sticks. There must be a reason for this. I wish someone would explain it to me. I am running at 9x 360. I tested lower multipliers, but every time I had decreased video performance. Even with the video set at 110. Thus, I hit a wall. I also only have air cooling and had unstable throttle down at greater GHz.
You may want to try it.

Sounds like your P5W was actually letting you run your Ram at speeds lower than the FSB. (??) Either that or the options were just reading as 533, 667, 800 always when in reality they were higher. On your P5W, did CPU-Z's memory tab really display a FSB-to-DRAM ratio like 5:4 or something? I'm not familiar with that board.
In any case, decent PC2-6400 C4 RAM can push 900MHz with relaxed timings. Are you willing to drop to CL5 and up your voltage? Might help. I hope I'm not spouting off the obvious. Best of luck.
AFAIK, the lowest RAM speed you can do at 440fsb with this board is 880 using a 1:1 ratio.
Thanks for replies....be nice if others had a little input..
Yes on my p5w i was able to have my fsb 469 = 3.7+ and my rams speed reduced to enable this oc, if my ram wasn't reduced from its original speed plus the fsb 469 increase theres no way i could do it. this board will not let me reduce ram speed when fsb raised???? iv never had this problem with any other board...seems really odd not to be able to reduce my rams speeds...reason i moved to this board was had more ocing potential!!!! seems i should have stuck with p5w
Cpu-z....i would be able to choose 533 or 667 when fsb was 460+ and cpu-z should reduced ram speeds.
