I have not read release note, but is you check AMD Driver Support page, you can find in Description of 13.1. Catalyst Software Suite That is why I installed it.

Cheers

One thing is, all those version numbers for the software items in that Catalyst package/suite do not tell a story about what improvements (or possibly new issues) are in store behind those numbers. A higher-numbered version does not guarantee that improvements were baked in. This is also true in the hardware front. Witness, for example, the industry practice of re-badging existing GPUs with higher numbers. All said, the only sure way to remove room for any ambiguity is to have the fixes, improvements, known-issues, and the likes documented in the release-notes and there is absolutely nothing for the Catalyst 13.1 package's release-notes that mentions anything that has a bearing with GPU-computing. If there are in fact improvements (directly or indirectly) for GPU-computing using the Catalyst 13.1 package, it surely is not documented.

P.S.
SekeRob, you dropped the ball again: confusing software description with release-notes.

Thanks for the replies so far. My cards are XFX and Sapphire, so I have downloaded both versions along with the AMD version for comparison. I have calculated Hash values for all:

AMD
CRC32: ED7E4799
MD5: 6E3E13F59D9A6631B81D7E574044E656
SHA-1: C06DAA8A4D709A26C8770A3F959B0B4C42BABF38

Sapphire
CRC32: B2D58C6B
MD5: 6EBB49B2D15066F7F4AA05B433622672

XFX
CRC32: B2D58C6B
MD5: 6EBB49B2D15066F7F4AA05B433622672
SHA-1: D12062F459188ADA182FE92B1A07FD36A118BD59

Its strange that the AMD should have different values. Digital signatures of ALL versions are the same however.

One new thing I have discovered is that there is no longer the option to check for updated drivers from within CCC. Instead, at the end of installation, you are taken to AMD site and invited to sign up for driver updates alert. (confirmed with XFX and Sapphire installation)

I can only presume that since both of these driver update files are now giving update alerts from AMD, there must be no difference between them even if the AMD version had different Hash values.

I am going to use the individual versions for the relevant cards in the meantime.

Think what's at WCG is not even a fraction, except if WCG[IBM] were to speak to them and tell them of the science application, the flappy ears would instantaneously perk up... but, you'd never get to know if they would. Anyone ever went to the AMD support forums and doing a sales pitch of the HCC-GPU success-story?


edit: Rickjb, what's the actual system juice use differential at wallsocket of your 7870 between idle and running 9, ideally measured with this 13.1 driver suite?
