I just buy a gigabyte ds3 and had to replace all other pc components, except dvdrw ?I had the problem with the ram - it did not start with the cheapest ddr2ram i could find - syncron 533 but after I rma it and buy a syncron ddr2 800 it worked just fine with a borowed pentium d940.?The cpu has temps at full load of up to 78 celsius.?I think it is caused by lack of thermal compoud, am I right?
