Hey guys

I had 2 GPU running, a 660Ti and a 610

Lately i got a couple of 750Ti's due to their speed/cost ration on NTLM

So i removed the 610, and installed the 750Ti's instead, and kept the 660Ti.

I have screens connected to them.

Windows only recognize my 660Ti now. in the device manager, the two other 750's are present, but in conflict,

'This device cannot find enough free resources that it can use. (Code 12)

If you want to use this device, you will need to disable one of the other devices on this system.'

My PSU is 775W, which according to my calculations is pretty enough.

Any help please?
hey guys, solved it

It was a BIOS problem, needed to update it.

Now that its on, I am only being able to get 2.5BH/s, tho Benchmark on previous posts indicated 5.1BH/s for NTLM.

Any thoughts?

How did you test? Did you use -b for benchmark?

Euhm nt exactly. I read it on a previous post.
Someone on the irc told me to use -w 3 to adjust the accel and loops, and using a list is much slower than bruteforcing a single hash.

I tested what he said, and i go up to 5.7BillionH/s :-D

My temp is constant at 70degrees, after an hour of 100% work now.

Is there anyway of optimising furthurmore?

Thanks alot Big Grin
