X48-DS5 stability problem; temperature related
Hi,
I've been having this really annoying problem with my new setup. The system is a GA-X48-DS5, 4 Gigs of Dominator PC8500 DDR2 (5-5-5-15, 2.1V), two videocards; one Radeon 5770 and one NVidia 9800 GT; CPU is a 6750 running at 2.66GHz; power supply is a Corsair 750W. Stock Intel cooler on the CPU, stock heatpipe on the motherboard.
Helped by this forum, I've been investigating my problem and found that with a blower (oversized for test purpose), I am able to stabilize my system. Without it, whenever the northbridge reaches about 40 degrees celcius, the system randomly crashes (even in the BIOS setup screen). Since it is an oversized blower, it does cool down all components but I've correlated these crashes with the system temperature reading (which basically doesn't mean much hey?).
Also, it would seem like temperature of he northbridge can be significantly higher and stay stable with the FSB down from 333MHz to 200MHz; leaving my system underclocked (right now, it is at 43 degrees).
I didn't have other fans than the ones on the heatsinks and power supply. I added fans, one in the front and one in the back (unfortunatelly, they are very silent hence not very performant) but still; 40 degrees celcius.... common, this chip can take much more than that. Timings shouldn't be affected this much no? Shall I play with the Clocks Skew?
Might I say that the northbridge is not very well placed as it is enclosed in a small space between the CPU, the RAM (very tall memory modules) and one of the videocards. It is hard to bring proper ventilation unless equipped with a case with a good side fan. (I'm so desperate that I'm thinking about getting a new case; a good 200 or 300 mm fan or even a 400 would be nice but let's try to understand the problem first).
I need the help of this forum again to help me understand what is going on. I left my system's bios at the default values and verified the different voltages and DDR2 timings and everything looks fine. I did however in my previous tests toy with the MCH overvoltage but with no success. Increasing it beyond +0.175V leaves the system more and more unstable (probably because of the faster increasing heat of the MCH).
Thanks,
