[ANN] MMC.1GH.COM - GPU mining, CPU mining ★

[SpeedDemon13]

I'm down to beta test a GPU miner for HD 6970 2GB.

Guys,

I have now a build of GPU miner that works with Nvidia. Its performance is rather disappointing, though: AWS g2.2xlarge (GRID K520) yields just 3.58hpm. It cannot be significantly improved upon. Consumer-grade cards would yield a similar or worse performace. Given that, please give your opinion on whether you would be using such a miner.

Would also definitely try - not sure if it works though. I have a new Macbook Pro

Unless you are just talking about testing, do your laptop a favor and stay away from mining.
GPU mining is very stressful and there is not enough cooling in a macbook.
There are cases of damaged laptops from mining...
And after all performance is not that great (your NVIDIA only consumes a max of 60W)

Given my previous posts... I think you can guess what my opinion is...

I can try it on a gtx 580 for testing to see what the output is and if I have under ubuntu some possibilities for tuning

I could try it if you want, got a gforce 680 2Gb

I have it in plans, but definitely after Nvidia (or Nvidia-compatible) build. Do not expect from VLIW cards any decent performance with MemoryCoin though, something on par with CPU perhaps, or even worse.

Really?
I thought that, for the price, it would be better than CPU.
Something around 4-5 HPM maybe...

Anyway you are doing a great job man!!!

Oh, do you think a 7870 Tahiti LE (same core as the 79xx series) will work with the miner?
Has anyone tried this? What HPM would you expect from it?

Again... thank you!

Price is not everything, VLIW cards have inferior memory controllers, and memory is crucial for MemoryCoin. 7870 Tahiti is fine, but I think noone has reported its hpm yet. If you are buying a new one, 280X is definitely the best bang for your buck, and not only for MMC.

Of course you're right.
But I know a lot of people that have built massive GPU mining farms with 5xxx and 6xxx cards,
just because they offer better kh per dollar than newer cards (on SCRYPT of course)...

So an updated GPU miner for VLIW GPUs will be great for those farms to turn to Memory Coin!

Also, you are giving priority to NVIDIA cards? Why, do you expect good performance from NVIDIA GPUs on memorycoin mining???

Keep up the good work man!

changed my settings to ubuntu from windows8


before: 17-18hpm, and unstable drivers was crashing. max clocks was something about 1050/1550
after: 21-22hpm, stable and max clocks seems 1125/1625 (but in default clocks it is already faster than windows with clocks)


edit: and card is Club3D 280X

Linux is consistently better for MMC indeed, across all cards. Must be related to a different videodriver model. Just wonder, why did you run an unstable driver? The latest Catalyst released (13.12) is stable, not beta.

i was using that 13.12 but it was not stable

Does this pool support long-polling?

No. Makes no sense actually at this hashrate (neither does stratum).

someone please explain me why are a huge different in performance between 7950 and 7970??
with my 7950 got 10 hpm >>> scrypt mining 650
with my 7970 got 19 hpm >>> scrypt mining 600

why is so bad the performance of the 7950??
Thanks

the 7970 should be faster in scrypt as well.  7970 is just more powerful in about every way

7870 gets almost 10 and my 7950 gets the same.. do you think the 2 gpu are the same?

The 7870 that does 10hpm is gigaherz edition, 7950 runs cores at 800MHz. This compensates for the difference in number of shaders.
