gpu-z only shows draw from pcie, which I think for newer cards is mostly memory related

Even so, If I'm getting 35 sols drawing 40w and someone else is getting 50 sols drawing 100w how can that be irrelevant?

You do the math  Grin

PS: I pay for my electric bill!

It's not completely irrelevant. But you absolutely CANNOT accurately use GPUz power draw to compare different cards because they all have different power characteristics. It's only good for doing apples to apples comparisons.

For example, mining Ethereum, I have RX480s that say 70~75w in  GPUz but this relates to more like 120w from the wall. So a 50w difference.

But my 290x, say around 130w in GPUz, but 200w from the wall, that's a 70w difference.

Basically, you have almost no way of telling actual power draw from the wall with GPUz, it's just a guessing game. And power draw from the wall is what actually counts.

And why do you need 2 x 850w PSU to power 6 x RX480? Even mining Ethereum at 180mh/s my 6 x RX480 only pull 810w, from the wall. You certainly don't need it for ZCash, I'm not even pulling 600w from the wall.

Really 600w for 6 480s, thats crazy.....Would 470s be slightly lower?

Not necessarily, but I'd have thought 470 should pull a little less. It all depends on the voltage you supply the GPU.

For anyone with Radeon 7950 / 7970 / 280X who wants more juice out of ZEC mining you can adjust your timings.

Mine went from 43 Sol/s --->  52 Sol/s. Running at 1100 / 1575

THIS IS ONLY FOR HYNIX MEMORY H5GQ2H24MFR . I will post Elpida and Samsung memory types later.

-------------------------------------------------------------------------------------------------------------

Basically you need to backup your BIOS ROM file with Atiwinflash and open with a HexEditor.

Here is the original bios strap for a Reference Radeon 7950.

Basically what this does is updates the higher memory frequencies with tighter straps.  For more info visit:
http://www.overclock.net/t/1554360/tahiti-memory-timings-patch-for-hynix-vram

This also makes ETH mining faster but only by 0.5MH/s but makes a huge difference with ZEC.

But you are not getting 35 s/s from 40w, get a killawatt and you will see your card pull atleast double that from the wall.
Sure, you pay your own electric bill but dont fool people with completely wrong numbers.

I'm not trying to fool anyone! Just sharing my results and settings like so many others have done, ok?
Sure you can share what you want but expect people to point out when the numbers are wrong.

Ok, I agree with you. I know it's not an accurate measurement. But it's a good indicator to compare different settings for the same cards.

The two 850 PSUs were a vital component when my rigs were a mix of 270x + 7850 +7970

Now they are quiet and cold...

IF anyone has any Cayman GPUs (6970,6990) you can mine with them on Claymore ETH miner however you need to start mining with another GPU that has at least has 3GB and then disable that GPU once mining starts. Since we can't use Cayman for ZEC currently.

Simply put, do what you can, use a BIOS mod, MSI AB or Wattman to drop GPU voltage as low as it'll go and remain stable. I find for mining Eth and ZCash I can drop GPU core voltage as low as 0.88v and still remain stable with 1125/2150 clock speeds. This gives 29.7mh/s in Eth and around 46~52 h/s for ZCash

Anyone care to share their Sapphire 11260-01-20G settings? Mine are running at ~50 flashed with my ETH rom.

Some people refer to this card as Sapphire Nitro+ AMD Radeon RX 480 OC 8G

My browser keeps me logged in 24/7, so if you see me as "online", it doesn't mean I really am.

I've modded some Elpida 280x before but I can't find them. If you search this forum, a few months ago someone made some optimized bioses for 380x and he posted the memory straps for the Elpida's. They are somewhere there.

Looks like right now if you have any RX 470/480

ETC PROFITABILITY = ZEC PROFITABILITY


Still more profitable to mine ZEC on 280x however.

Going by Nicehash and Whattomine data

Has anybody noticed if this miner needs more PCIe bandwidth like the genoil miner did?

We're still not sure the PCIe bandwidth is a limiting factor, though it did appear to be a possibility with Genoil's miner. Genoil's miner was very CPU hungry too though. My Celeron and Pentium chips would be at 40% CPU load with Genoil miner, with Claymore miner they're in low single digits CPU usage. But certainly claymore's miner is much quicker for me on my 6 and 7 card rigs.

I'm getting almost twice the hashrate with my 7x 290x rig.
