Topic: Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux) - page 209. (Read 3839398 times)

At 5 x 150w + 95W + peripheral you should be fine. That said, I'd personally prob go for a 1200w PSU since the price diff isn't huge between 1000w->1200w

Doesn't matter in my case since the 480s only require a single 8-pin (or 6+2)

Hi everyone!

Please help me with advise. Will it be enough to put 1000W PSU ( Chieftec APS-1000CB ) on 5*RX 470 4B with AMD FX-4330 CPU + 1 SSD ?

People say that this GPUs can draw up to 200W on some peak consumption. If it is so , then PSU is not enough for that RIG ?

It is precisely on this refining of the settings of each different graphics card that the tool could have a utility. It will make it possible, for example, to test, for each card, optimized settings with a tolerance greater or less for their stability and all this automatically with backup of the logs.

Remove stupid
GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

and put the right environment variables as need:

SET GPU_FORCE_64BIT_PTR=1
SET GPU_MAX_HEAP_SIZE=100
SET GPU_USE_SYNC_OBJECTS=1
SET GPU_MAX_ALLOC_PERCENT=100
SET GPU_SINGLE_ALLOC_PERCENT=100

And please read careful README, from two version of miner parameter GPU_FORCE_64BIT_PTR need to be equal to 1, depending -i parameter that increasing of intensity growing video memory usage.

What do you want the software to change? You want it to dynamically change the clockspeeds based on profitability? i dont think you want that. You always want cards to run as efficient as possible unless you dont have to pay for the power bill.

There is software that will switch mining algorithms based on profitability (like Nicehash). But you will still have to finetune the cards yourself. Every card is different. One card can do 1250 MHz on 1.0v a second one will do 1325 and a other card only 1175. AMD already does some voltage binning based on chip quality's

I have 480's with 1,075v stock and also cards with 1,106 and 1,150v.

Hello everybody
I just recently launched myself in zcash mining and I currently have a RIG with the following hardware:
 - 6 rx480 nitro oc 8gb from sapphire
- 1 mother card asrock b85 anniversary
- 1 psu Corsair CP-9020094-EU RMX Series RM1000X
- 1 ssd 120 go
- 1 2 + 1 gb ddr3 1333 (awaiting change for 8gb)

For now the bios of each graphics card is as follows: Anoraks_Sapphire RX480 8GB Samsung Rev53_original.rom (https://anorak.tech/uploads/default/original/1X/eab04521348d2a51fb89e0a1e634b038bed1e76c.rom)

After several tests and taking control of the tool Claymore's ZCash AMD GPU Miner v11.1, I have heated my settings of each graphics card (using trixx utility) to arrive at the final consumption at output of RIG at 780 watts with a total hashrate of ~ 1450 H / s. My total power limit is -50% and the gpu voltage is set to negative according to each graphics card according to the stability tests I have performed.
My question is the following :
Considering the time spent adjusting the parameters of the rx480 individually on trixx utillity and config.txt of claymore zcash miner, is there any software that could allow to combine incremental tests on the different possible settings of the graphics cards with the claymore tool And in combination with the maximum of automatically selected profotability?

. A kind of software that would do all this in an automatic and controlled manner (a kind of nice mining evolved)
If this software does not exist, you will be motivated to start this project.
I think that this will have a great interest for many people and will thus save a lot of time on the settings therefore of the stability system but also on the money earned.
I do not have much knowledge in programming language but I am ready to participate actively in the project.
What do you think ?

Thanks to you for the many informations that help me to start my first RIG.

What are your clockspeeds? maybe the card is throtteling (check with GPU-Z)
You can also try higher core and memory clocks to get 260-270. With a bios mod with strapped timings / stilt timings you can get 280-290 maybe a bit more. But then you need to use older drivers.


Dont think so. Does not seem to be a very special driver. Just some bug fixes compared to 16.12.2 (game related + relive related)

AMD Crimson 17.1.1 can make a change for Polaris cards ? (In the next version CZM v12??)

I only got 240h/s on 11.1

Im using rx 480 8gb stock rom

Can someone share his confg, or Am i missing something?

Thanks

Same for me 260-265 H/s stock no bios mod

That's the same H/s for my RX480s.

For ref. RX470 4GB, stock bios, -i 6, CZM 11.1, I got ~232-240H/s.

Heт.

That's a realy nice number for a R9 390, always thought 390's are closer to 300sol/s than 400.

stock bios?

Thanks for the site, I also did not know it yet!

But I would not say negligible.
For example: running a PSU at 88% efficiency instead of 94% sounds (and looks on a 0-100% diagram) not much different, but produces DOUBLE the losses and heat! Many people oversee that fact. You can also see similar on the input/output diagram on the left if you compare the values of 50% and 80%.
If it justifies the price difference for the larger PSU is another, individual story. That's why I personally don't like such monstrous single bricks. For the given case I for myself would select 2x 750-850W PSUs depending on the current market.

But we are too OT now. ;-)

Latest version give me 260 H/s. Bios not modded.
