Dear all
i have some 290x cards i am looking for best C/memory setting to give max hashrate in zec
i try 1050/1450 and result is 330h/s in some cards but do nothing in r9 290x gigabyte windforce - max is still 277h/s
also i have some 280x - 285x - 380x nitro cards i want to know also the best setting for it
i use win7,,8, and 10 in different rigs with 16.9.2 - 16.8.2 drivers v11.1 claymore

could be a difference in memory. I think the 330 card is a Hynix card and the others might be Elpida.
To get more out of them you can do Stilt timing / memory strap mods to the cards. You will have to do a setting in the motherboard BIOS to get the cards working since the vga bios is edited. But it works fine.
There is no ideal clockspeeds for max hash. as long as your memory timings are low. Higher clocks are better. If you go to high memory will give errors ECC will correct it but you will be slower then. Higher clock = more power usage if you pay for power you might lose money istead of making money. Thats why most people undervolt cards and somtimes underclock them a bit for better efficiency.
For 280X also timing mods! -asm 1 helps a lot but without timings are key. with stilt timings you can get 235-240 with hynix memory. And with ASM you get 270 (that was with 1000-1375) if you go for higher clocks 300 is possible.
thanks for your reply you can say that electricity is almost near to free and i only want to adjust clock / memory setting
Every card is different. One will do 1100-1450 a second 280x will doe 1150-1500. another one will do 1200-1425. So if you want the max performance you have to tweak every card individually and find its limit.

one question please:
since there is no polaris ASM kernel coming, everyone who has mixed rigs now (e.g. r9 fury + rx 470) is going to split them up to install driver 15.12 and run ASM kernel for their older gen cards. Is it worth it for r9 nano and r9 fury?
thanks!

thanks!
i thought you need to run different driver versions anyways?
no, r9 fury and nano run fine together with rx 470 on my driver 16.11.5 ~ 1510h/s@580w
I guess not many here have mixed rigs then.
I could not get ASM to work with the 16.12.x drivers. I will try the 16.11.5 and hope that will fix the problem.
No i have to run 15.12 to get it working or not run the Nano in ASM mode.
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 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.
I only got 240h/s on 11.1

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.
AMD Crimson 17.1.1 can make a change for Polaris cards ? (In the next version CZM v12??)
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)
i use 295x2 to mining, now hashing at 560 sol, this normal?
I'm afraid so. Im currently working on one and i have a hard time getting it above 300 sol/s per GPU.
I got it up to 306 now. With claymore V11 -asm1 -i 5
Clocks 975-1375 @ 1.105v
Memory timings are 1250MHz strap.
15.12 drivers (still having problems with newer drivers mining software just crashes after a few sec)
Timings did the trick to kick it +20 sol/s per GPU higher.
Voltages are bios modded card seems game stable so its not at the stability limit for mining.
But somehow these cards wont go as fast as the 390X. I also think 290X with different Hynix modules and Stilt timings would do even better.
When i test oclmembench im at +- 250Gb/s a 7970 with stilt timings does +- 230 with 1375Mhz. And those cards do +- 270 sols with 1000-1375 MHz.
ASM is more effective for those cards tho. Without they would do 235-240.
Only thing i can do now is do the 390X MC bios MOD but i have to do a lot more reading on that. Not that simple to do. Took me some time to figure out the timings but thats easy compared to the MC mod.
i use 295x2 to mining, now hashing at 560 sol, this normal?
that seems to be low for 2x290s a single 290x is over 300 solsDid you do the mod yourself? or did you download a premade bios. I have seen those for the 290X but not for the 295X2. Not enough people owning those cards.
I do not have experience with the 295x2, but I can image you hit the limits faster than on single cards.
My 390s (non-x) are all running average above 360 H/s with OC and stock BIOS.
And yes - my modded 290X was even doing 380 H/s (!) - and also cooler than stock. I now reduced the clocks for stability as it's the primary card in a workstation, but it's still at 355-360 H/s.
I dont know Cooling is not the issue. Power delivery is also a non issue. It really seems to be localisations of the memory timings and controller.
Thats also what makes 390(X) cards so much faster then stock 290(X) cards. With a bios mod they are just as fast.
Seeing the stock hash rates compared to my strapped bios makes me think there is even more to gain.
Im currently underclocking the core but thats because i only have a 1000 watt PSU in that system. And it needs to run 5 GPU's. Stock the system with the 295X2 mining solo (other cards where connected but not mining) was already pulling 524 watts from the wall and with all cards i was hitting 1024watt so optimizations where needed. Core voltages stock are 1.25v way to high if you ask me. I got them down to 1,1v with a clockspeed reduction of 45-50MHz. (stock 290X is 1.2v if im not mistaken)
I might optimize the card more if i have time. But i only have 1 so the gain is not that big. Its mostly for fun

Soo, better speeds for polaris and 390x on today's release?
Maybe maybe not. I thought Hawaii 290(X) and 390(X) already had ASM support.
380 and 285 (Tonga) did not. Same with Polaris. So who knows wat magic Claymore can do.
Maybe we will have to wait a while for ASM + Polaris.
guys can you tell me about hashrate of r9 380?
you can get max 175 Sol/s on v11that sounds way too low. perhaps 275?
No its not. Its a 380 not a 390.
380 = R9 285
Its similar to the R9 280 and 7950 but The 285 and 380 are GCN1.2 vs GCN1.0 and it has a 256 Bit memory bus vs 384 Bit. Shader wise it has the same 1792 shaders but a newer architecture. Fiji (Fury Cards) use the same 1.2 architecture.
R7 260 Bonaire and R9 290/390 Hawaii use GCN 1.1.
Memory speed and timings seem to impact performance quite a bit. I had a 7970 with Hynix MFR memory. it did +- 200 with timing mod it went up to 235 sol/s stock memory clocks core 1100. Memory OC on stock timings got it up to 210.
im getting ~260 on a msi 7950 that takes oc to the max thats why i'm so surprised
There are 2 reasons:
1: More memory bandwith and maybe lower latency (timing mod for the 7970 helps if you have Elpida en MFR memory AFR has quite good default timings). Also see RX480 cards that clock high compared to Tahiti and only get 250-270 ish. (there are people that report a bit higher sol/s with timing mod but then you cannot use the latest drivers)
2: ASM support only added for Tahiti and Fiji so far. That boosts performance quite a bit.
The next version of Claymore's miner might have a ASM option for Tonga based cards. Hopefully he can also add it for Polaris.

They are now doing +- 255 on 1000-1375 MHz with V11.
It's not needed he uses Watttool
GPU 1180
Memory 1750
both running at 904MV
true that. I never go above 1180MHz for the core on the last phase and it's never over 925mv.
btw memory read intensive dagger-hashimoto doing fine on 850mv (total power from these 6 is below 920W in dual mining)
eth only is 816W:

Zcash v 11 is doing quite good.
Undervolted 4 x cards I get 1046 H/s and 360 watts at the wall.
what software both of u use for that ?
Maybe MSI Afterburner.
You can also edit voltages in the drivers with AMD Wattman. I use the latter. You can set voltages and clockspeeds for multiple steps. not that interesting for mining but it is for gaming. But could also be usefull if you switch to a algo with higher load and temps. If you set a power limit it can switch to a lower speed step with lower clocks and voltages to save power. A custom bios would be nicer. But then you cant use the latest drivers.
With MSI afterburner you do have to option to change the values at the same time for similar cards. But the weakest card will be your limit then. Other cards might be able to run the same speeds at lower voltages or higher clocks at the same voltage.
guys can you tell me about hashrate of r9 380?
I have seen multiple listings in this topic. So search a little.
Google can also help.
If i remember correctly it was +- 160-170 ish.
Will the new update of the miner be today?
No. I plan to release it tomorrow, need to check different drivers to improve compatibility.
Nice! Maybe this solves my problem with the Fury Nano and Nitro that i have. They cannot run ASM they go to 0 sol/s. So i force them to run normally.
Tried lower clocks and drifferent drivers but so far it was not working.
7970's are doing very well with V11.
I also had a problem with a R9 295X2 would crash after 1-2 shares. Did run stable with old 15.12 drivers but wont work with newer 16.12.2
Thats to bad because with wattman support in new drivers you can tweak the card way better. Fingers crossed for the next version
