What is the basis for this, and how to correct? Morten ID: 37650 · Rating: 0 · rate: / Reply Quote

Last modified: 22 Mar 2010, 15:12:24 UTC Purely asthetic - they have the same GPU, just that the 5970 has two of them. Its early days for software writers to catch up purely on labels. Give it another couple of months and no doubt they will. At the moment BOINC shows a 5970 as [2]5870's in the computer summary page. BAM shows them on startup as: ATI GPU 0: ATI Radeon HD5800 series (Cypress) (CAL version 1.4.556, 1024MB, 2608 GFLOPS peak) ATI GPU 1: ATI Radeon HD5800 series (Cypress) (CAL version 1.4.556, 1024MB, 2608 GFLOPS peak) ie labels both GPUs as 0 & 1 respectively.

Regards Zy If this is so, then someone is hardcoding the info. Best practice is reading from the card or operating system. This will get the correct info. Even a pre-5970 GPU-Z version will correctly read 5900 series.... ID: 37654 · Rating: 0 · rate: / Reply Quote

GTX 295 is in fact 2x GTX 280, and as I recall has never been classified as GTX 280 by Boinc. Perhaps the Boinc developers have a preference for Nvidia ;-) ?
