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

[carlo_0000]

if you  wanna also do cpu mining, you have to put cpu miner in task manager to idle  otherwise you gpu is gonna be slower

V2.0 killed one of my rigs:S I think CPU dead and 2 gpu dead:( sad sad day!

Report a bug.

On a serious note, it was likely your PSU crapping out taking GPUs and CPU with it.

What type of PSU was this ? bronze gold or plat ?

PSU- EVGA SuperNOVA 1600W and 1300W.
I tried them, works fine on another rig! i will get new CPU 2 morrow and will se- but 2 gpu of 6 are dead!

That sucks its only happend to me one time, i usb riser overloaded and fried one of my cards so watch out for bad risers

i know- will cost me like 10 000 norwegian krone:O very sad day- take 2month to get the money back:S
always worked fine for many mothns no problem- use v2.0 and here we go- killed the rig.

What about the RMA, most cards have 2 year waranties

[Marvell1]

why bother with SC it used to pay for power costs now even with 50k hash in SC you make $500 usd for the month, its not even worth the power anymore

mining ETH by itself is better imo

You mean that mining SC as a second coin is not profitable? It takes more electricity than I can earn?

i think unless you eletrity is less than 10 cents per KWH it does and remeber its more stress on your GPU's for little gain

I'm getting an extra 15 soles and the cpu usage is low. If i use -i 2 i get 20 extra but my cpu loads to 90%. Great job claymore. U're the best! I'm using an 7950 hd shappire.

[persiansstuff]

v2.1:

- added "-i" option for adjusting mining intensity and CPU usage.
- improved speed for high intensity mode ("-i 2"), about 60H/s on stock 390X, 50H/s on stock 280X.
- since nicehash cannot upgrade their ddos protection, now "-allpools 1" is required for this pool.

PS. OpenCL API uses CPU to wait response from GPU in high intensity mode so it's not easy to fix this issue completely, currently you can use "-i 0" option if you have low-end CPU.

Hi

Thanks for great work

please do something like i4

I think my cards(390s) still could do better

dont know but im going to check with the website  i got i from and ask if i can return them- had them for like 5 month now.. i think its 2 years waranti i norway two...

Glad to see some performance improvements. 62H/s on Fiji and 50H/s on Tahiti.

Added another 5% or so on all my rigs with older cards using the -i 2 switch.

On my Rigs with newer cards, such as the RX series, I actually seen a slight decrease versus version 2.0. I have tried all three intensity levels and even the -i 2 gives a bit less sols and the CPU usage is greater than in version 2.0. I am still playing around as it might have been my lowered clocks, but it seems this version was geared more toward the older cards.

Yes I did not have time to improve performance on Polaris yet.

I get about 2-3H/s boost each version on all my 470s and 480s, 4GB and 8GB versions, most sapphire some others. Just have dual cores, mostly celerons, one APU.  You can try setting ZecMiner priority to above normal in task manager, it may help slightly.  Also check if other processes are using much CPU. Surely there is more room for improvement on Polaris, but I got boost from 1.1 -> 2.0 -> 2.1

[flyingdutchmen]

Will there be a miner for mining two coins at the same time, like ZEC and ETH?

Thanks for the clarification! Great job though on increasing the performance on the older cards. Now I know to focus on tweaking them and not worry about my RX rigs for now, I'll keep them on V2.0.

10% improvement on 290. Great work as always Claymore. Let's push it to 100 Sol/s shall we
