post #11 of 14
fan is a requirement i think on heatsinks just cause the heat doesnt leave with out it and if you dont put a fan on i dont think you could get past 2.3/2.4 honestly.

I hope the mounting brackets are secure
1. I don't know, never tried without. According to a guy who did tests on XS, it's better if you have one fan to have it in a "pull" arrangement rather than push.

2. Near a kilogram with a fan - I've had zero weight related problems on a naked CPU mounted vertically in the case. I couldn't mount it the "stock" way for reasons that I can't remember on my ultra-d, in case you have the same problem I'll go ahead and type out what I did (works with cpu's with or without ihs) -

Buy the following
-2x 1 inch 6-32 diameter screws
-4x 6-32 size wingnuts
-6x washers that fit on the screws

Put it through the back of the board in this order - screw, washer, motherboard, washer, wingnut; tighten this so that the screws are securely held. Now, to mount the cooler, you just place it on the screws, throw the other two washers on each side, and tighten with the wingnuts.

I'm glad you had great success, but I wasn't so lucky and even some pro OCers have had issues like Anand, here are some reviews where the FSB didn't get very high while keeping a nice CPU multi.

So yes, there are some a8n-sli boards that will do 300fsb, as in primer's case, but 90% of the reviews and threads I have read suggest that this is not the normal case. But once you get your new setup installed let us know how it goes!

Either way, you would be better off with opty since its dual core.
my board lets me do 300+ fsb
im now at 310x9 with mem freq of 199(means its at 1:2 ratio?) and i still havent tried lowering my timings cause one thing confuses me. do i set my Memclock Mode to Limit from Auto? if i do that then i see that the memclock value is 100 mhz then should i lower my timings?
