If anyone has the p-state checker I would be grateful...
any information if 4100/6100 can be unlocked to 8100 as of yet?
AMD stated they can't be. Probably hardware locked somehow.
aha, ty :)
it won't ever be. Avx,fma4,xop are useless for current simulation methodsQuote:

There was/is in this forum. I seen someone done very good job with NB scaling and memory scaling. NB scaling did not give any increase of perf. Though everything was pretty much flat as far as I remember. Sorry no link, but I am sure it is somewhere in AMD sectionQuote:

Issue with my NB tests was the unability to go over 2800 on air... I needed to go cold to pass it and to test 3200Mhz.Quote:

Now it would be nice to test a MSI or GB board to compare efficiency vs the Asus board. Something feels not right....
With P2 I think it was that nb stopped scaling after its 3*mem speed (base, eg. ddr3 2133 would need ~3,2GHz NB).Quote:

Up to 3% for a CPU-intensive style benchmark, and it can vary highly in
a microbenchmark depending on workload and compiler.
Does anyone know if the patch made it and it may be interesting running some tests on linux before and after?
what you guys think about this? more BS or maybe its true? its bubiks news i just done some digging and found a link.
AMD Bulldozer Registry Fix?
AMD FX-8150 Passmark CPU Score has jumped from 8500 to 13000 using REG Patch. But it is not stable yet.
Do not listen to the critics and hardware sites that do a few generic benchmarks and come to a conclusion.

The boys over at Kubuntu has been working on a AMD Bulldozer fix that sort-of applies across several platforms. The ARM Cortex-A9 8 core processor had a similar problem that was overcome with a software patch. The problem right now is that the patch has to be re-registered with each Windows start. Look for a 40% performance boost if this works…. more to come.
There is most definitely a Windows 7 AMD FX – software patch in the works. By most estimates the AMD Bulldozer FX is underperforming by 40-70% in most Windows 7 benchmarks.

The news about this "miraculous" patch are spreading around many forums.
Waiting for some XS user to confirm .... if the patch exists and if it works.
Well if that's true then it'd be the 40% speed it's desperately in need of to be a real bulldozer!
? magical patch?
Seems kinda doubtful to me, maybe in a few specific situations it would work but I dont think it is suddenly going to make BD perform a lot better on average
Lies i think.....Quote:

Which is a shame....because http://i.imgur.com/kxLI8.png
So there is hope for Bulldozer after all? It needs a miracle patch to show its real performance and optimization? Hope so.
"miraculous", "magic" - silly words thrown around by people.Quote:

So it works far far far better in Windows 8 ? If you can get performance up by 10-20% that would be excellent, 40-70% is utopia... then it would be close as being the fastest CPU out there.... IF AMD knew this then they rather had waited a few more weeks for this "patch" Same for the CH V is too slow discussion, if I compare my stock nrs with sites that have used other than asus boards I see not much discrepancies...Quote:

And regarding CH V, i suppose AMD had a deal with ASUS that AMD provides cpus for reviewers and ASUS provides motherboards. They couldn't change the motherboards because of obligations. And most of review sites just took that system and tested just that system, while some others tried other motherboards.
I myself will be getting MSI. Its my 3rd MSI in a row (790FX, 890FXA) even though I was planning on getting asus.
40-70% :D
Man imagine that? Suddenly a wild bulldozer appears, Sandy bridges not very effective.
We can dream, right? :D
Personally, I wouldn't expect 40-70%, though I would like to be wrong about that.Quote:
