The Stilt Improves SuperPI Performance on AMD Systems
Overclocker "The Stilt" from Finland has managed to optimize SuperPI performance on AMD systems, and all you need to replicate the results are the patch and some liquid nitrogen.
It is widely known that AMD-based systems aren't particularly performing well with SuperPI performance. This was previously blamed on the architecture, though it now appears that this was simply a BIOS development limitation on AMD platforms.
Finnish overclocker the Stilt has managed to solve these optimization issues by using BIOS developers' guides, and increasing SuperPI performance. The result is a simple patch that can be run on both 32-bit and 64-bit installations of Windows.
The previous time record for a 32M SuperPI run on an AMD Richland chip was 18:15 -- the AMD A10-6800K managed to pull it off within 17:34 using the patch. While not a big difference in time, do consider that the A10-6800K APU was running at just 4.1 GHz as opposed to 5.0 GHz, and they have the same architecture.

By the way, do you really need liquid nitrogen for the A10-6800K to be running at 4.1GHz?
4% gain on a BIOS patch.
The differential is not large, but its certainly a good thing (especially when we are talking about a simple APU refresh.
It makes one wonder, how many other possible optimizations were missed by manufacturers (who seem to have been giving AMD solutions a hard time left and right in the mobile sector).
Used to get 16m 57s with version 1.5.

4,1GHz is stock frequency for 6800K
I think he already is a legend lol... this only makes him more... well, legendary.
AMD should hire him, great addition to their drivers team. considering SuperPI is a part of the benchmark suite on almost every review site, it's amazing that AMD's drivers team didn't figure this out earlier

AMD doesn't really care about 20 year old software that nobody has to use any more. This still doesn't make up for the fact that x87 is pointless towards the future or really even the present. AMD has better things to do than focus on improving performance in a useless benchmark. If they cared at all, they could have put a real x87 instruction decoder on their CPUs.

I agree that SuperPI no longer has any real world applications. however, I must stress again that it is used in almost every benchmark suite on tech review sites. AMD should care about SuperPI and such "useless benchmark" performance because it pays off in marketing. it's just like how Intel's "Intel Inside" stickers have zero relevance, or the boat loads of money they spent buying off OEMs etc. in the end it's all about perception, and even if real-world performance is indifferentiable, the synthetic benchmarks will give people the impression that Richland chips are "worse" than they actually are.
The say $100-500k a year they can spend hiring the Stilt to do some work for them will be way cheaper than the marketing budget they'd need to make up for slower performance in benchmarks etc. besides, that guy knows what he's doing, it's not like he's just some idiot who stumbled upon this.
Is the instruction set related to the CPU or the motherboard ?
Why would you call an instruction set a BIOS patch for the motherboard ???
And who's responsibility is it to write it in the first place ?
One thing I'm certain about AMD is that it doesn't place any importance on writing proper instruction set code on anything !
