Title: How to get high khs on 7950 i-13? Post by: tenaciouzd on January 21, 2014, 11:22:33 PM I see people saying they are getting 700+ khs with undervolting and only intensity 13? Highest i can get on my 7950 is 650 with massive OC's and OVERVOLTING and i-20 rendering the px completely unusable, wtf? If I could get mine to do that kind of hashing on that intensity I could use my computer still with no issues. I have tried all sorts of settings on gpu engine memclock tc etc that i have searched and even tried to find the perfect one for my card manually inching engine and clock settings manually till my pc locked. anyone can explain? Its not that I dont know how to OC or anything, i had hte #9 highest score for a single 7950 gpu on the valley benchmark thread over at overclock.net. How the hell is it possible to get that much hash out of weak OC and undervolting? I dont even care about conserving power. I want max hash rate.

Post by: jasemoney on January 22, 2014, 03:31:48 AM they are using -g2 instead of -g1 with thread concurrency closer to 8000 not 24000, any higher intensity with -g 2 will cause major HW errors. Monitor your temps. I can get 660khash script on my 7950 but i prefer to run it closer to 500khash for longevity.

A lot of 7970s can handle g2 nicely though. My XFX 7950 does 630kh/s, -g1 -I 20 -TC 20408. Still tweaking the settings though. |
