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

[titusr1]

Hello, I have RX 550 2G and before with monerov7 I had 498h / s, now I have monerov8 415h / s. Before the Auto intensity was 25 in V7 and now in V8 it is auto 26

Oke running Adrenalin 18.6.1 and SRBMiner V1.6.8 cryptonight v8 gives me per card 71 H/s less

Doc,  Switch over worked great, thx for your continued support...

Do we need to tweak any of the setting for V8 or will the v7 work well?

meaning card settings..

Not the same settings, depending on the card the intensity is about the same as on V7, but the worksize 8 isn't working out very well for V8, 16 or 32 is usually better.

how does this affect Intensity if were increasing the worksize to 16 or 32? I noticed a drop in the hashrate as everyone else is, going to the machines after work, so was trying to get any updates on settings for the VEGA's, 570/580's & 550's.

thank you for your time!

Same ,

I have 6x vega 56 on v7 11500M/H with worksize8
now on v8 with worksize16, inetnsity default 0
1000M/H less.

I try to play with intensity but ....didnot manage to get back this 1000M/H.

For me...

V8 using same settings than in V7 I have:
RX 580 4GB +10 H/s from 996 to 1006
RX 580 8GB Same than with V7

Tested different intensities, also used Worksize 8, 16 or 32, I have same H/s

Using modified Blockchain drivers for W7

[-manki-]

My Vega64wc gets 2060H/s on v8 vs 2200H/s on v7 ,BUT... using same settings(1456/1130@870mV) GPU starts to throttle down to 1300MHz as Hot Spot temperature increases to 110C+
I have to lower clocks to 1250/1050 to keep the Hot Spot just under/at 100C and hashrate drops to 1900H/s(while still using 30w more power from the wall). Is Monero team trying to free the world from Vegas?

As for miner settings I'm still figuring it out, 123 intensity, dual threads and 16 worksize at the moment. W10, 18.6.1 driver

anyone using vega frontiers ? they are only doing 1300 mhs at 1400/1100

[Dscha]

Several 580 Rigs:
~918H/s with CastXMR
~970H/s with SRBMiner

Are those SRB numbers realy 100% legit?

Same here 

[digitalunix]

Maybe SRBMiner mining cryptonight-webchain soon?

[bruslie]

is it important worksize in config ?

i tried 8 and 16 and 12
i think no any effect. any idea ?

yes me, blockchain driver is RIP about 1200 hash / s on vega 64

[doktor83]

Guys, you won't get back your V7 hashrate, this algo gives less hashrate and consumes more power.
The most affected cards are Vega's.

[doktor83]

heyho, Im new to SRBMiner since today. All my Vega Rigs are running fine so far...except one

Im trying to give each card manual settings, however it doesnt seem to work -> always get parseError. These are the settings im trying to use:

"gpu_conf" :
[
   { "id" : 0, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 1, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 2, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 3, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 4, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 5, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 6, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 7, "intensity" : 120, "worksize" : 16, "threads" : 2},
   { "id" : 8, "intensity" : 120, "worksize" : 16, "threads" : 2}
]

what am I doing wrong?

Thanks in advance

Post the whole config, this part looks OK

I have 6x vega 56 on v7 11500M/H with worksize8
now on v8 with worksize16, inetnsity default 0
1000M/H less.

I try to play with intensity but ....didnot manage to get back this 1000M/H.

I got about 1000 h/s on old 18.3.4 drivers. updated to 18.6.1 and everything went ok. worksize 16, intens 112 for vega56, 124 for vega64

one rig has a problem after drivers updating from 18.3.4 ( initializing opencl devices and nothing happens on 18.5.1 and 18.6.1 (

I will try to re install driver,using 18.6.1 now.

For now using defaults I:120 W:16 double treads.

P7:1407 P61212,Mem 900 mhz

mv 910 ,905, 900

and rig is using more power 1180w befor 1020

Hey Guys,

i am just setting up a new RIG and got an error i had never before...

I run 18.5.1 Driver with Windows 10 (last updated) and last SRB Version

When i start the Miner, the Wndows opens and the text says, Initialising open CL driver/cards.... but than nothing happens.... verry strange...

Any ideas?

THX

Can you post your string?

[camchimonline]

V8 more power than v7, hash drop down than v7

[oxzhor]

V8 more power than v7, hash drop down than v7

Hmm see the same here it use 140watt more ...

[vitalyoff]

RX550 2G
"intensity" : 27, "worksize" : 32, "threads" : 2 = 447 h/s (510 v7)

RX560 2G
"intensity" : 27, "worksize" : 16, "threads" : 2 = 463 h/s (485 v7)

RX560 less hashrate drop than RX550
