Dam i decided to see what cooling memory will do for ocs and man I'm surprised by 1GB OCZ PC3500 Plat LE BH-5 on AI7 at 3.18v

--------
no cooling

max prime stable = 240mhz 2-2-2-6 667fsb strap A-A-A-D-D
max benchable = 242mhz 2-2-2-6 667fsb strap A-A-4-D-D

--------
strapped 60x38mm delta 50-60cfm fan on the top mid section of the ram modules with TT fan speed control set to high


max prime stable = not yet tested but can do super pi 32M at 245mhz 2-2-2-6 so far
max benchable = 250mhz 2-2-2-6/7 667fsb strap A-A-A-D-D

-----------------
updated to 17 official bios and increased unbuffered scores!

:cool:

Note: cpuz on AI7 reports wrong cpu/ram ratio when NB Strap 667fsb is used and swaps 1:1 and 5:4 around.

256MB still aren't as fast as 512MB sticks in dual channel on P4

Cool :cool: results (pun intended).

Looks like air cooling is worth 10MHz on the FSB. I am looking at cooling the RAM in case this is the reason why I have errors with Q-PI.

Did you use a kit or pull soemthing off the shelf? Have you heard of a kit (something like plug-snap--n-go?). I have seen one from Thermaltake but it looks like thier fan is integrated with heat spreaders (I would have to take off the heat spreaders on the OCZ RAM before I could use the Thermaltake cooling unit - not found of doing that).

Thanks for sharing your results.

Snafu i just placed the Delta 60x38mm 50-60cfm fan onto of the 2 ram sticks in the middle. Taped a piece of cardboard on one side of the fan so it flushed against the side of ram stick in dimm slot #3 and taped the cardboard to the ram stick using masking tape. Then taped other side of the fan to the Corsair Hydrocool's waterblock retention spring on my the P4 bracket.
