Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[un4given]

small noob question. cant find any hint in the FAQ file.
how can i stop claymore from closing if claymore cannot connect to any pool? sometimes the connection is lost and claymore restarts and freezes all my rigs due to driver problem. can i set claymore to try the connection as long till he connects?

ok, so you want me to read through 550 pages or use a search function which showed me exactly nothing i could use as an answer...but u r so cool writing all in BOLD...u r really proud of yourself, are u?

Interesting fact: after modification timings Gigabyte HD7950 gives stable ~330H/s with 1% rejected. (1190/1470) - Pic 1

If increase mem frequency up to 1500, GPU gives ~361 H/s. But about 15% of rejected. In log file appears strings of buffer overflow. - Pic 2

What voltage do you have to overvolt to get it stable at 1190 Mhz core?

would love to know that too. my fully oc msi 7950 only gives me 260, those numbers are what i get with a 290x modded as 390x

The most under stock voltage is maybe 1100mhz core clock or so. With 1190mhz I am guessing he needs it running at 1.25V or 1.30V, which is never a good idea on any Gigabyte Windforce GPUs since the triple fans are very weak.

And I am sure that would pull very close to 300 Watts at the wall from that 7950.

It turns off watchdog, and if a GPU crashes it doesn't auto restart which causes any Rx 470/RX 480 to instantly freeze the system to the point where it needs to by phyiscally power cycled.

No idea if it does the same thing if a pool dies.

Hello. Who has the video card Sapphire Vapor R 280 x. What should be the temperature of the core and memory at Mining on Claymore. On my memory card temperature rises to 90 degrees. Without overclocking. It is not right? What to do? On the other coins storage temperature of 70 degrees. Thank you.

what percentage is your fans running at?

my 280 non x version is running at 75 degrees with 39% fan with out overclock giving me 236h/s

you can always use the -tt command line function to set a target temperature for your card. once it hits that the fans will increase to try to keep it at that level

[wacko]

Vapor series were meant like "super overclocked" cards so they came with really high stock voltage, you need to undervolt the card to get reasonable temperatures.

v11.1 Linux version released.

Thank you.

Thanks Claymore, keep up the good work 😀

Thanks. Updated to 11.1 on my Ethos rig: http://ethosdistro.com/kb/#adding-claymore

I understood. I put option -tt and I will try. Thank you.

Can you will prompt how to do it? Or give me a link to the instructions ?. Thank you.

These are really old cards so there's a shitload of information out there, just use google.

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 Updated to 11.1 .

thanks for your reply you can say that electricity is almost near to free and i only want to adjust clock / memory setting

What does this buffer overflow mean ? Obviously, hashrate indexes is not very accurate ?

What voltage do you have to overvolt to get it stable at 1190 Mhz core?

Stock voltage, 1.195V. For 5 years, since Litecoin, no problems. Gigabyte Windforce.

Interesting, what's "solutions buf overflow" mean ? If the author made logging, and it turned on by default, would be great to understand the data.

[TimLev]

Are you overclocking ?

No, using stock cards.

Anyone else have a 'GPU #0 returned incorrect data!' error? Happens on GPU #0, 1 of my 4 Saphhire R9 280xs, after about 6 hours of mining. It's always the same GPU returning the error, while the others are fine.

Had such happiness with one card. In my case, solution was a significant drop in temperature. Probably some radio elements lost characteristics with age and at high temperature becomes unstable.

What temps did you have before/after? My GPUs are hashing at around 68-74 C.

>72 C - incorrect data, <63 C - correct data But this is strictly individual.

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.

Hey Guys,

I have an r7 370 that is not recognized anymore. The fans are spinning but Windows/Linux cannot see it

Since it has never happened to me before am i looking at a burnt card?
