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

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

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.

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 to 3828/3801 MB/s!

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



So guys cool ya ram!

Nice work. Thanks for going through all the trouble to take good screen shots and show all you benchmarks. 8mhz is a nice over overclock :)

3.18V ? dude, I wouldn't do that for too long. if you start smelling burnt silicon you'll know why.

He also is using extreme cooling on the ram so dont think there is anything to worrie about, though it will likly reduce the life expectancy

winbond bh-5 is spec'd to theorectical max 3.6v volts, so 3.18v with 60x38mm delta 50cfm fan @ 8180rpm isn't that bad :D
