Our colleagues over at the TechReport have some new information regarding Intel's recently released Pentium Extreme Edition 955 (Presler). They had a bit of trouble with their initial sample that has since been resolved, but the solution had some unwanted side effects.
"You may recall that we had some problems with our Intel Pentium Extreme Edition 955 setup that caused us to delay our review a bit. The motherboard, CPU, and cooler combo we received from Intel for review didn't always cool the CPU sufficiently under load, leading to thermal throttling. We've now tested a production Intel CPU/motherboard/cooler combo, and we have some good news and some bad news."
