**This thread is for benchmark results only - post questions in other threads**

Geth GPU support is coming soon, in the meantime, the C++ miner is out.
The purpose of this thread is to post GPU results, not CPU.

First, install the client:
https://github.com/ethereum/cpp-ethereum/wiki/Installing-clients

Second, run eth -M -G
Of course, you'll need a GPU for this to work. Use --opencl-device 0 if Eth is not identifying your OCL device properly

Third, post your results!

The format is:

OS / OS version / GPU / Eth Version
min / mean / max: xx / xx / xx
Inner mean: xx.xxxx MH

Please post everything in MH.
Please do not post questions etc as they will be removed.


Update:
14/05/15 - corrected typo on opencl, clarified thread rules

HWinfo64 no memory errors detection

Hi everyone!

On HWinfo64, I got "0" memory error from my 4 Sapphire RX 570 8GB GPUs but on ethermine's dashboard I got up to 8% stale shares. The current hashrate is very random also, it goes from 83,+ MH/s to 136,+ MH/s for a reported hashrate of 121,+ MH/s (reported on claymore also).

>> Hardware:
- MoBo: gigabyte H110-D3A
- CPU: Intel Celeron G3900
- RAM: Corsair Vengeance LPX 4GB DDR4
- SSD: Kingston A400 120GB

- Dual mining ETH (ethermine.org pool) + DCR (suprnova.cc pool, 3% of rejected shares generally)

When higher OC, I got errors on claymore only (or freeze) but still "0" error on HWinfo64.

I tried older versions of HWinfo64 and the latest Beta version without any change.

Anyone knows how to fix this HWinfo64 sensor problem please?

Undervolting issue on PULSE RX 580 with any values

$
0
0
Hi :#,

So I'm using the blockchain drivers from last year and I'm trying to undervolt using Claymore. I have only installed the drivers from device manager for Display Adapters and not used AMD software or anything.

I started with:
- cvddc 850
- cclock 1170
- mclock 2125

And I get random hangs from GPUs even for higher values of cvddc, even if those are getting very close to the default value. GPUs start having issues as soon as 20-30 minutes.

Seems to be running fine (for weeks) only with:
- cclock 1170
- mclock 2125

But I kind of need a bit of undervolting.


Also I'm not using the following parameters for Claymore:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100


Anything that I could be doing wrong here?

Thanks,

SMALL MINING FARM PROBLEM, ASUS RX470 4GB MINING EDITION

$

Dear comunity,

I make this post because we are trying to make a small mining farm with 100 rigs. this are the spec:

- ASUS RX470 4GB MINING
- ASROCK H110
- CELERON G3930
- 4GB DDR4
- 2 X CORSAIR RM1000X/I

https://i.imgur.com/boVIGuL.jpg

https://i.imgur.com/TDhLVtA.jpg

We got also few rigs with Nvidia 1070 and 1080ti, works perfectly. but now making this new project we found those issues:

- Randomly crashed rigs, we use simplemining OS and Ethos. I'm pretty sure that there are not defects on those rigs, until they were moved to the big place they work months without crash. Now we encounter randoms crash in differents rigs everyday. Do you know if possible both OS cause trouble on the same LAN?

- We ordered from asus the most part of our GPUs, the RX470 4gb mining edition. Since now all we mount are ELPIDA memories.

https://i.imgur.com/kPSWK9c.jpg

https://i.imgur.com/HnfmOEw.jpg

We modded the bios very carefully, they seems to work with the mems (1900 and 1000mv) and leaving automatic voltage on gpu, timings are set on 1500 straps. We tryied to do more undervolting on mem but seems to crash, also gpu without automatic voltages give lots of problems.

About 10% of the total gpu lot are defective, they don't mine even with stock settings, they crash to 0 mhs on claymore. Do you guys have any clue on this?

I will be very thanksfull if anyone could provide me support on this. Any details you need please ask me.

Best regards,

share submission latency issue

ok so ive been mining for about 4 month now, i have 1 x6 gpu mining rig and a 2 laptops at work, the mining rig share submission take 210-280 ms but at work it takes 140-190ms and its confusing the shit out of me even tho more people are connect to the router at work!

both office and home have the same isp with the same speed and the same exact router

also i tried a wired connection at home to see if any improvement will happen but that was useless i got worse latency than wifi

i have tried TCP optimization which worked and got me about 210-250ms but im still not satisfied, my stale share rate is jumping between 5% 9% on ethermine.org

should i buy a new router? i researched online and 99% of the time its barley the router that gives long latency


what could it be? any ideas...

Biostar TB250-BTC PCI-E x16 slot not recognizing card with riser cable

I was running this rig with a card directly plugged into the pci-e x16 slot until I was able to pickup the last two cards. I assumed the pcie-x1 riser cables would work with this slot. I did notice it says it's a PCI Express 3 slot, does that mean I need to get the x16 riser cable?

Solution for bad fans.

I had some bad fans that wouldn't spin or that would wobble so bad they would hit the shroud or heatsink. Can't get stock GPU fans.

I just finished installing new 120mm fans to my second rig, I'll do my third rig tomorrow. Temps are great, and fans are quiet. This is a great solution if your fans are going bad and wobbling. If anyone is interested, for $20 I can get you 2 fans and wires, you'll also need thermal paste and zip ties.

RX 480 blew up!

$

Hi all,
my Sapphire RX 480 8GB GPU which was working stable in my rig, blew up yesterday, causing a small flame and a terrible smell coming out of the front.
What caused the damage I cannot exactly tell. It came actually out of nowhere and suddenly popped.
I took some pictures to let you see if anyone knows which part of the card blew up.
Maybe somebody has some advice if the card still could be used for replacement parts or something else.
Let me know.
