Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[davembg]

Woo, Finally figuring out my bios mods
4 PowerColor RedDragon 4GB cards
I got them to 30 MH but they were unstable.
29.9+ is what I could get stable
2100MHz mem at 1242 Core

That's HUGE for those cards. High 25's is all I can get with my Saphire Nitros (480X 4GB) on Ubuntu 15.10.
Clocks are 1306 core, 2000 mem. Any faster on the memory and the cards die or just won't post.
You apparently got REALLY lucky with those cards.

What OS and driver version?

Just solve the problem. I puted 16.4.1 (you can try the other ver) opencls amd_opencl64.dll and amdocl64.dll in miner folder and it generated DAG successfully.

Btw it was for R9 270 (2GB) and R9 290X (4GB).

What OS and driver version?

Windows 10 Anniversary
AMD Driver version 16.11.5
Core clock set to 1242 (Was actually the magic number across the board for these)
Mem (Samsung) set to 2100 using the strap of (This was the magic clock for me. As using the 1500 Straps always crashed the cards)
777000000000000022CC1C0010626C49D0571016B50BD509004AE700140514207A8900A00300000 0191131399D2C3617
Powertune % set to 50 max (Never exceeded +25% on the poor ASIC cards)

One of the 5 cards is only using 55w (93% quality ASIC) but all the others are 125w+ (Asics of 69-81%)

I also have about 9-10 Hrs in each ones Bios finding the best TDP (W), TDC (A), and Max Power Limit (W) for each card. Very slow fine tuning but this is also my first round modding bioses with a goal in mind.

For Eth I get a faster hashrate on windows but for Equihash, Cryptonight I get faster results on simplemining os.

I dont mind a few % rejects, its realy a small amount.
The temperatures are the problem, i can get the RX series cards to 70 - 74 degrees, which is not that bad, but the 79xx series just goes 80+ hehe.

Can anyone tell me what the degrees are on 280x cards for istance? Im guessing they overheat to, since its basicly at 7970 repacked.

Regarding those RX, set the core clocks to 1050, thank me tomorrow

Thanks for the tip, im trying it out.

So far, ETH drops from 24Mh/s to 20MH/s  

Anyway, im geting bad results on SApphire Nitro+ RX 480 4GB
About 24MH/s ETH + 1.1Gh/s Decred is the best i can do at 1300/2000
Kinda sux, seeing people are geting 28Mh/s ETH on 470's.
Even if i tune down Decred to oblivion, ETH won't go past 24.5Mh/s  
Noobs shouldn't mine hehe.

you modded bios vga? or default ? thank you!

That was default.
Now im running a modded bios, geting 29.5Mh/s ETH + 0,75Gh/s Decred ( 1200/2150 @ 1.000V - temp 60C - fan 50% )
The 4Gb nitro was actualy one of the first batch of Nitros that was in fact a 8GB card, so i flashed it into a Nitro 8GB

How much does your cards consume at 29+ mhs?

I have burnt 2 motherboards and many riser when they exceeded 120w per gpu core. (not wall, just core watts)
So i never push beyond 100w now. I am curios about the maximum power allowed per core.

GPU-Z is reporting about 120-125W GPU only power draw.
It's strange you would burn motherboards, pcie + 8 Pin power should be enough for quite a bit more than 120w.
Whats ur settings to go below 100w, and what is the hash rate at that wattage?

Wich part of motherboard did you burn? 24 pin maybe? It is because of unpowered raisers besause too much current goes through MBO to power the gpu's. You must use powered risers. I also have burned MBO and power suply 24-pin connector when I had more then 4 gpu's with unpowered raisers.

It wasn't the actual motherboards just the pci-e ports. Ports stopped working after smoke came out of them. Yes i am using using powered risers (ver 7s).
25watts per card is too much price to pay for +1.5mhs anyway. I wont push them to hard.

This is 200W from the wall!

How did u calculate this?

Man, i really need a power meter 

[coinzoid]

Do we need to set virtual memory to 16GB even if we have 16GB/32GB RAM available on system?

[Demented247]

Hi Claymore, may we please get an update on Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v7.4 (Windows/Linux), currently this is the most profitable way of mining and usually the most consistent. I'm pretty sure this should also gain from asm improvements.

[Qazo]

can someone help, best settings for sapphire 480 OC 8gb , stock bios - mining only eth
on stock settings I get 24.8 mh/s

drivers 16.12.2

p.s. i don't care about electricty, just stable settings


edit: hmmm tried this one
core 1100
memory 2180

and I get this
ETH - Total Speed: 51.315 Mh/s, Total Shares: 21, Rejected: 0, Time: 00:28
ETH: GPU0 26.569 Mh/s, GPU1 24.746 Mh/s

why is GPU0 have much more hashes than GPU1 ?? they have identical settings, temp etc.

And I got it 30MH per RX470 4GB
The trick for the last 1 MH was finding the perfect SC Intensity for me it was 17

That is Great!  What are your watts at the wall?

[EuroCanuck]

1500 straps? over/under clocks? my xfx black 4gb(elpida) 470s i can get a max stable of 1150/1975 and 28.3mhs ..with sia at any intensity that goes to 28.6 ...not worth the extra power.

1242 Core/ 2100 Mem

2100 MHZ mem using the 1625 Strap the card was unstable and was maxing out at 27.7MH using 1500 Straps but the 1625 strap got me to 29.9 with SC at I 20 but my goal for the rig was over 30MH per card so I thought about it for a single card in a rig the best I could find was a SC I of 20 which got eth to 29.9 but when they are put into a 5 card rig SC I of 17 brought all 5 cards up to over 30MH.

I don't know my wall power but I am using a 850W Bronze PSU CPU is a old Phenom II x4 965 Black.

cant really believe this....
what processor do u use?
How many rams?
Motherboard?
core voltage and power limit?

how many incorrect shares?
and what about stability?
you sure your talking rx470? if yes is it MSI, Sapphire or which?

Why work it? The Poles are well digging and interest drip with us! And so everything is fine. Sea, women, margaritas !!!!
