The Bulldozer Review: AMD FX-8150 Tested
by Anand Lal Shimpi on October 12, 2011 1:27 AM ESTOverclocking
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.

The reason for mentioning the 2600 is because that's the only comparison we have for the moment. I don't expect Valencia to use as much power as Zambezi even on a clock-for-clock basis.Pipperox - Monday, October 17, 2011 - link
That has to be seen.Bulldozer's HUGE 16MB of total cache surely were not put there for desktop workloads.

I am quite disappointed with the overall performance. And specially with gaming performance.But what about that rumored patch fix for the BDZ? Has any of you guys at AnandTech heard of that?

You mean this one?http://quinetiam.com/?p=2356
Interesting if it's true, however it's doubtful to help across the board (pun not intended). Still, very good news for those doing rendering/encoding.

I never want to see a link to that dickbag again..His blogs about WW3, bigfoot, & 2012 should be enough to give you an idea. Also, the dudes at Kubuntu basically do repackaging & KDE integration. They don't touch hardware.
No doubt there can be significant gains through software. But I would rather stab myself through the eyelid than read anything more by that 'person'.

Yeah, that one. I know that there is a very slim chance of that 40% boost ever happening, but the idea behind the "patch" is actually plausible.I've seen lots of people explaning how would it work and it looks somewaht legit.
Granted that 40% is too much, but if the right tweaking, I'd be more than happy with 20% to 30% increase in performance!

everyone would be happy with 20-30%. It doesn't seem realistic to me... but i dropped out of computer engineering :pFrom what I've seen, I would guess about 5% [+/- 5%]

Turns out he was one giant troll, or seemingly so. Now, he's pointing the finger at..."Problem solved, it’s just a thermal protection issue, people have been pushing voltages too high. Maybe there’s some variance in mainboard chipsets, but some overclockers and hitting really good numbers."
Really? After all that hoo-har about registry patches, BIOS flashes and the like, we're now blaming thermal protection? I'm taking this with a litre of Dead Sea water.

Hey, there has to be somebody somewhere that we can all laugh at. ;)That said, he does sound a bit... odd.
