Title: (SOLVED) 5850 Low mhs new build Post by: hmblm1245 on January 19, 2012, 11:12:25 PM So i order a few 5850s from bens outlet (OEM) built a new win764 box with 11.12 and SDK2.6. using cgminer i set the following
Engine 900 Mem 300 volts (default) And my results were locking and freezing right after i launched cgminer. so i dropped the engine to 840 and now my mhs is 300. I switched to SDK 2.4 and the 11.6 driver package and get the same results. This feels a bit low for a 5850. my current hardware config is 890fxa gd70 1 gb mem sempron 140 500 watt psu any thoughts? Title: Re: 5850 Low mhs new build Post by: dirtycat on January 19, 2012, 11:19:55 PM i run mine at 825/300 and i get 290mhs
I also had the same problem with it lockin up and crashin at 850 Title: Re: 5850 Low mhs new build Post by: malevolent on January 19, 2012, 11:28:45 PM Mine doesnt lock and crash @ 940-950 (depends on the cards) / 300, with standard (1.088V) voltage (it's a sapphire extreme non-ref)
What brand is it? Reference or non-ref?

I also have a visiontek reference running at 920/500 on another box doing 370 on 11.6 and 2.4 sdk. it seems really low to meWhat brand is it? Reference or non-ref? Title: Re: 5850 Low mhs new build Post by: hmblm1245 on January 20, 2012, 04:26:34 PM So i solved my issue. I completed the steps in the following order
1. deleted the partition 2. installed win7 3. installed ati 11.11 drivers pack 4. installed SDK 2.5 5. installed drivers for the rest of the missing hardware 6. configure CGminer as followed Engine 920 mem 500 volts (removed line from json) default the rest fan 45% temp 65 -70c Now i'm getting 370 stable with one card so i'm guessing that it must have been some left overs from the SDK2.6/11.12 driver package. Title: Re: (SOLVED) 5850 Low mhs new build Post by: siggy on January 20, 2012, 07:00:46 PM hey.. thanks for posting this... I had/have the same issue with those very same Ben's Outlet cards....
just to clarify one point... the exact drivers you are using are 11.11c ? thanks, Sigg Title: Re: (SOLVED) 5850 Low mhs new build Post by: hmblm1245 on January 20, 2012, 07:38:03 PM Um not sure. in the CCC under info - software its driver package version 8.911-111025a-128243c-ati
hope this helps Title: Re: 5850 Low mhs new build Post by: yjacket on January 26, 2012, 01:03:32 AM So i solved my issue.

Are you getting the 100 cpu bug?

my 5830s clocked at 942 only get 290m/hash but ive been to lazy to get SDK 2.1 Title: Re: (SOLVED) 5850 Low mhs new build Post by: hmblm1245 on January 26, 2012, 02:45:14 AM its a 5850 not 5830
