[Official] AMD Bulldozer Reviews Thread - Page 50

post #491 of 2308
AMD indicated the FX-8150 was good for around 4.6GHz using air cooling, 5GHz using water cooling and beyond with more aggressive cooling methods. In our experience with the platform hitting 4.6GHz, stable, on a stock AMD HSF was not an issue. Moving beyond 4.6GHz on air saw a significant decrease in stability however. I could boot and run benchmarks at 4.7GHz but I'd almost always encounter a crash. I couldn't hit 5GHz on air.

Theoretically, that gives AMD a glimmer of hope when it comes to overclocking but, in our tests, we had mixed results. Boosting the FX-8150 to 4.2GHz was straightforward, but the system became unstable at 4.4GHz.

You think it might be due to lack of power from the PSU?

More like Pentium 4 X8.

My article should come sometime tomorrow on this forum and others.
Something I will look into. Will wait for that

What was your facial expression when you first started using the chip?

reviewers use like overratted review sample PSUs, they don't under power the system.

I thought Bulldozer was the name of the overall Architecture around which several chips were based, and ZAMBEZI was the "codename" for the FX Desktop Series Processor based on that Architecture?
Yeah but the codename isn't showed anywhere. None of the review's Cpu-Z shots show the codename Zambezi.

AMD needs to go back to the drawing boards, bye bye AMD for a couple of years.. till they rethink things for a while.

I'm still interested to see what these chips will cost over here, when they eventually arrive here. The benchies are disappointing though..

The worst part about this is that Bulldozer is supposed to be the result of AMD rethinking things for a while. Sad.
