Hello! :D (And hardware question)

[mvd7793]

Hello bitcoin forum! I want to PM one of your members so I'm making a post here.

I do have a hardware question. I have an ATI Mobility Radeon 4670 in my laptop. Does it work with any GPU miners? (As I don't think it supports OpenCL. DirectX 10.1)

Thanks!

if it doesn't support opencl, it won't work with gpu miners, sorry

Aww that's ok. Here's another question.

Looking at MtGox's ticker data returned by the API, it seems in almost every given scenario it's giving a profit based on their rates.

Specifically:

https://mtgox.com/code/data/ticker.php just returned the following:

{"ticker":{"high":24.5,"low":16,"vol":73423,"buy":19.3444,"sell":19.5981,"last":19.3444}}

Which (I think) means that a Bitcoin was just bought at the rate of $19.3444->1BTC, and a bitcoin was just sold at a rate of $19.5981->1BTC.

As they have a trading API, wouldn't it be possible (and why hasn't someone) written scripts to take advantage of this difference (as it's greater than their .65% fee)? (I just want to make sure I'm not thinking about it wrong.)

$19.5981*.0065= 0.12738765
$19.3444 * .0065 = 0.1257386

So theoretically, assuming those rates were held constant, you'd make a (very small) profit by going from 1BTC --> USD --> 1BTC. Is that math correct?

Thanks! Sorry for the strange question.

Mobilities actually do support openCL.

I found online that ATI cards didn't support it until they supported DirectX11 (I'm 10.1), and OpenCL wasn't supported according to GPU Caps Viewer. Is it a download I need to find on the internet somewhere, or should it just work?

ATI Mobility Catalyst™ 11.4 Driver Suite 1 is needed for OpenCL Support on mobility apparently... and 10.1 should still work, If not then 4600, and 4800 series wouldn't of supported it.
