Title: Possible TPM use to improve CPU mining?
Post by: Un zafado cualquiera on July 03, 2011, 04:10:02 PM
I was reading a lot of things and maybe I found something useful (or not). Because I am not programmer (not a savvy one, at least) I want to ask somebody if this is a posibility of improvement.

On this PDF says the TPM has an SHA engine. In argentina there are 3 million of computers with this module.

Is possible to use this service or not.

is can AFAIK only do sha-1, and we need sha-2.

but i does not think in any way it would help much some VIA processors haves sha-2 engines, but they don't gives much Mhash

VIA has an SHA-2 like the ones on HD cards?
Maybe the miners are not aware of that...

Is more...I think is possible... On the discussion about the FPGA miner use the function for verifying anyways.

it has been tested, but it did not give a goo Mhash/s

TPMs are generally very slow chips, so it won't help you with mining at all.

I was thinking it's more like reduce the load on CPU. Thanks anyway.
