SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching

[doktor83]

but i have 2 rigs. rig 1 is not affected. only rig 2. here are my specs:

rig 1:
sap rx 570 nitro+ 4gb (samsung)

rig 2:
powercolor rx 570 red devil 4gb (hynix&elpida)

Now that is really strange, both cards are 570 4g, i will check what is happening.
Regarding hw errors, that means the result GPU returned could not be validated on the CPU, because it's wrong.

If you have a few errors don't worry, but if you got a lot i would start with lowering intensity.
Intensity can be a decimal number, so for example if you now use 35, you can try 34.5. If not satisfying then 34 and so on.

Doktor, don’t know if this is possible but can you let the gpu run idle when there aren’t any jobs from the pool? Less heat and power waste.

Hello Doctor

I have these cards on Asrock h110 13slots

2*Rx 560 4GB--------500    h/s
3*Rx 470 4GB--------670    h/s
3*Rx 470 8GB--------880    h/s
Rx 480 8GB----------1050   h/s
Rx 570 4GB-----------700    h/s


my hashrate dropping alot

its not intensity problem , ive tried alot of numbers with/without double_threads

swinging hashrate -20%

i set virtual memory 100 GB

Dok, is there a way to set a constant difficulty? I think I am getting better hashrate when I am mining on lower difficulty tho, that's why I am asking

Hello
I'm using 2 old RADEON 6950 on 2 different computer. It's the 1st miner could hash from the Monero V7 fork and I'm happy to discover this miner!  

I have a hashrate problem, I can't reach better than 145 H / s. Before the Fork I was doing 350 H / s with this card with other miner.

I've tried the automatic intensity, and a lot of between 0 - 300 i've got the max with intensity 15
Is this card compatible with this miner ? Already it is stable and there is HASHRATE. Which is not the case with any other minor i've tried ...

I hope you could help me with my 2 old radeon card.

I'm Using Windows 8.1 X64
The last WHQL Driver for this card "15.7.1"

There is some recommendation about the driver revision or other tips to Hash more with that card ?

Thank you for your work

@doktor83

I quoted myself

Any idea about this card ?

The blockchain driver did'nt work and the laster beta drivers didn't work too.
So only the WHQL 15.7.1 driver works at low hasrate.

Since the hard fork claymore doesn't support older card than 6xxx, i think u have a lot of old miner could be interested by your miner, i saw same problem on other forum as mine with this  6xxx card can't hash, SRB Miner is the only one could hash with my card.

I've tried 1.3.0 /1.3.1 / and 1.3.2 version with same result.

I hope you could help me.

The blockchain and latest drivers won't work with this card because it is a pre-GCN card. Probably need custom timings in BIOS and overclock memory to get better hashrate.

Ok and what about the hasrate 350 before hard fork ==> 145h/s after ?
I know it's a very oldcard, but 700h/s on two card was prety good for those grandma  

i'm at the maximum OC AMD Override let me put : Gpu 800@840 Memory  1250@1350, Memory speed didn't impact the hashrate. It's seems the miner didn't take all the GPU "powerfull"

Which miner did you use previously? Probably better optimized kernel or something to give better hashrate. SRB probably isn't optimized for older cards, maybe try with XMR-STAK?

Hi there

This config for normalv7, i set intensity,   fixed value  (example: 44) ----> it's run  and has good hash (for xmr coin)
{
/* Type can be : normal, normalv7, lite, litev7, heavy, ultraheavy  */
"cryptonight_type" : "normalv7",

/* Intensity 0-> auto intensity, or value from 1-200  */
"intensity" : 44,

/* To use 2 threads per card set double_threads to true  */
"double_threads" : true,

but i change to heavy,  it's not run and has bug (for sumo coin)
{
/* Type can be : normal, normalv7, lite, litev7, heavy, ultraheavy  */ 
"cryptonight_type" : "heavy",

/* Intensity 0-> auto intensity, or value from 1-200  */
"intensity" : 44,

/* To use 2 threads per card set double_threads to true  */

Please help me

This card does 400 to 450.

Mine does with Claymore, not with SRB.

Hey dok,

What's the word on all the rejected shares when mining at nicehash (about 5%)?
Could a fix be found?

Getting both outdated and invalid nonce rejects.
In comparison, gateless gate gives 0 rejects but speed is not on par poolside.

This card does 400 to 450.

The Lexa RX550 does 450, but not the Baffin RX550 with slow 1500 MHz memory.

1.3.2
Vega56 - same hashrate as CAST-XMR, ~1800-1900 (GPU 1474, MEM 920, PL -15%) blockchain driver.
Its good. Now i will test stability.

{ "id" : 0, "intensity" : 120, "worksize" : 8, "threads" : 2},

hi there

u must use half intensity

heavy using double memory

try 22 instead of 44

Miner 1.3.2 cant't shutdown if crash detected. System also can't reboot in this case. Only reset can help.
CPU usage in this case is 99%

Also in version 1.3.2 i can't see which card is crashed.

I am having this same issue. The only thing in the log file shows "watchdog: GPU crash detected, miner will try to restart" and then it hangs with 99% CPU usage. Version 1.3.1 didn't do this.

Can you add in the logging which GPU ID crashed to help narrow down hardware issues. Right now I don't see how logging is of any help.

good work.. thank you

This urgent. My rig crashed after 20 hours. But which gpu?
