@PrimeGPU, What are the outlook for 5800 and 6900 compatibly ?

What speed increase does a 7970 offer compared with a, say, 4core 2 year old PC (64bit) ?

~50x when comparing to i7-920

Please explain how you reached such a bold conclusion.
Well, I've got both i7-920 and 7970.

The AMD Radeon 7xxx series is known for having weak 32-bit integer multiply units.
And?

Also, what is the point of this software testing exercise?
To prove the community that the GPU miner really works.

I believe that it works, but the question is how much faster than an i7-920. 50x i7-920's should solve a block every six hours on average. Weak 32-bit integer multiply units means that a 50x performance gain is not even theoretically possible.

sounds about right.

Yeah, it is. I could replace it with I3, which is a bit faster. Xeon will probably stay in my main comp for now.

"Time" I have around 290 on all 3 cards. 3x Sapphire Vapor-x @ 1070 Mhz. I found 1 block so I am glad that this miner actually works.
You surely need to try "-cpuusage=2" or even "-cpuusage=1" setting.


There is almost no difference in cpu usage between -cpuusage=1,2,3 setting when looking at cpu usage in task manager. It jumps between 58 & 64 most of the time. Looking at the Time, it is the most stable ~280-290 on setting -cpuusage=1 & 3 and no real difference.

I fixed my rig now so it is running 4 cards. Immediately after I started the miner with cpuusage=2 and 4 cards, the miner found another block.

2 blocks found so far.

Thanks for letting me be a tester currently updating wallet up to date.  Hoping after to see what this can do!

That would mean that i7-920 has 0.13 CPD. It doesn't.

Weak 32-bit integer multiply units means that a 50x performance gain is not even theatrically possible.
Ok then.

Will you sell it ? What will be the price and when can I buy it ? Guess it's time if it works.

I'll leave it be...the compensation is enough for a few days of testing with no blocks.

As for the license, I keep getting pm's asking for the links and whatnot...the miner won't work on your systems even if I gave you the info, since it's linked to your hardware/system. (good idea devs, otherwise this would have been mtrlt's primecoin gpu miner 2.0 fiasco) -> this one actually works :p congrats.

I'll post some more info tomorrow, hopefully after finding a block.  Cool

-cpuusage 3 made my miner more stable regarding Pass-es and time.

what's your cpu?

Celeron g1610



That's a bit weak :p

I had a g465 but chose the i7 for this.

EDIT: is that time variable an indicator of performance, estimated remaining time to block or what?
It's lower now, went from 1020 to 1100mhz core and added the cpuusage flag.
Yep, its an indicator of performance - the lower the value the better. It's time in 1/100 seconds it takes to process a chunk of data (i.e. "pass")

Hello, Can i be a tester ? I have R9 280x to testing.


Thank you for your great work!

Yup, it was around 50-60% on 4 threads...got an i7 3820.

Added that flag to the server and clocked the core higher, 1100/1500mhz.

i7 3820? ayyyy, fancy cpu.

what's your time now?
