Okay... update...
After two hours of messing about... I got the board that needs to be hot at a stable 73c, but it now shows 'FAULT' on one of the VRMs.
Even with the fault, the miner is showing 260GH/s average on CGMINER and 244GH/s on the pools side, both of which are slowly climbing. My 5s averages at around 271gh/s - 302gh/s.
I'm much happier with the speed now, but worried about that 'FAULT' on one of the VRMs.
What do you guys think?
Also, my Device Rejected rate and Pool Rejected rate has shot up from around 0.27% to now over 5%.
EDIT: Thanks Searing for the suggestion, but that is the first thing I did when I got my Miner. Keeping the temp cool isn't my problem. My problem was to actually heat it up. My miner normally ran at around 45c on one board, ad 48c on the other board. Now I have them at 65.5c on one board, and 73.5c on the other board. Never seen it run better then now. Just hoping to keep that stable.

Same here with "Fault 4" with a VRM. Tha asic went very well up to 0 Cores OFF and about 75°C....but since 3 days...this vrm pulls more and more amps as much more i have more temps. now the asic can run only about 65 °C because the vrm at max 50.2 AMP...over that temps tha VRM pushes more and it get the message in red "fault 4"
P.S. i had VRMS in a Saturn that worked with 58,8 AMPS very well.
What does the "Fault 4" state exactly mean?
Hi,
Fault 4 means "overtemperature".
Try adding some small RAM heatsinks on the top of the DC/DCs.
Also check the front fans and ambiant temperature.
PS: This fault code activates when then DC/DC converter exceeds 130'C. It will shut down at 145'C. It is not OK to continue running your miner that hot !
73'C for the board temperature is a lot too. You are stressing the components.

Hi Uski,
i have allready heatsinks on it since the first mining day. But i don't belive that there are 130°C at this VRM. I think it is faulty.
Do anyone know how to use an other of the 4 unsed VRMS instead? i have boards with 8 vrms but as we know only 4 are used of them.
