X48 Rampage Formula Preview.

Much better, now idles at 41c and loads at 48-50c, great cooler for 20 bucks, my stock wasnt even making contact with the NB fully.

here is a pic

It's a very cool cooler, myself was thinking of getting that one or one of the thermalright's chipset coolers.

Could you tell me the NB voltage you're using when it gets to the 48-50c?

I check temps and voltages with pc probe II, but don't know if they are accurate, at least the CPU voltage and temp are the same as the ones on CPU-Z and Real Temp.

With the stock heatsink, prime95 on load, PC Probe II reports 46º with NB on 1.23v
Maximum temp I get is 55º with NB on 1.44v
I have 6 fans on my case, upgraded the window panel fan to a aerocool 140mm, but don't know if those temps are true, I'm no experten, but doesn't seems much temperature difference for 21 volts of setting change.

My RAM settings are all in auto, except the voltage and speed.
On my daily 400 FSB overclock and also when I test 444FSB I have them on the 2.1v max and 1066/1067MHZ.
Still trying to find the NB, FSBT and SB limit for those BUs speeds. Haven't tryed to go beyond their 1066MHZ limit or change the timings.
