Hi, i have a rig of x5 5850, custom case, so all the GPU are realy separated from each other and all with risers....To power is suplied by 2 x CL SP 700w, and the temperature never never go more than 52c. The fact is that i cant overclok the rig more than 850/300 so im onl getting 340mhs wich is realy bad for a 5850.
When i try to go more than 850 it fails. The OS (BAMT) stops responding so i have to reboot manualy the rig. Dont know wich the problem could be. I have to change the OS maybe ?

I have the same problem. But with 865mhz+ on coreclock, i got driver stop and reboot. With Sapphire Extreme and XFX, both 5850.
Would like to increase coreclock, without changing the voltage.
Give the details of that rig so we can discard posible erros.
I have 3x 5850 (2 Xfx, 1 Sapphire extreme) on a motherboard (ecs a890gxm-a), and core/mem configured (865/320) with AMD Gpu Clock Tool, and fan set manual in 60%, temp are in 65-70°.
But if I try set more 5mhz to coreclock (870), after 5-10min i got blue screen.
OS: Windows 7 Ultimate
Driver: 11.7
Voltage: stock
What you say? =/
