Hi,

I'm running rhminer on an old Dell R610 with 2 x Xeon E5620 2.40GHz CPU's (16 cores with hyperthreading).  I managed to get use of another server so upgraded the CPU's to 2 x Xeon E5649 2.53GHz (24 cores with hyperthreading).  Both the same OS (Win 10), same firmware, drives etc but the E5649 CPU's have a hash rate about 1/3 of the E5620.  Higher clock speed and more cores, I was expecting more.  In fact, I have have an 8 year old i5 4 core desktop running with a slightly higher hash rate than the server.

Anyone got any ideas?

Thanks

OK, ran v1.2 with GPU and it worked.  It picked up my GTX770 but there was no real benefit.  I was only getting an extra 40-50H/S more and my system was less stable.  When I'm getting around 1000H/S from the CPU it made more sense to go back to v1.3 and just use the CPU.

I have seen people reporting speeds of 600MH/s from a GPU (https://bitcointalk.org/index.php?topic=1778118.0) so was a little surprised to only get about 50H/S.

OK, I see I need v1.2 for GPU.

I'll give that a go.  Thanks very much.

I'm using v 1.3.

I'll take a look at the discord too.  Thanks.

Hi,

I'm new to all this but have got a a couple of old servers mining plus my desktop.  My problem is that rhminer is not finding my GPU.  I've checked it's supported and it is (GTX 770).

When I ran the rhminer -list command all I got was CPU information and when trying to run using the GPU I get a message something like -gpu is an invalid command.

Does the card require a specific driver version?  Any help would be much appreciated.
