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

[Bojcha]

Talking about power... CNv2 (Monerov8) does use quite a bit more. Getting very close to the acceptable limit on my 1500W PSU on that 6x Vega rig. I need to undervolt a tad more.

Bad decision from the Monero team, this new algo draws a lot more power, and gives less hashrate than the previous V7.
Monero's price should go up if they want people to continue mining their coin.

but fees will be smaller

Ok so I seem to get pretty much the same hashrate on v7 and v8 on my RX 570s.

59/8/2 for v7, 1225 core, 1940 mem = 955-960 h/s
57/16/2 for v8, 1225 core, 1940 mem = 955-960 h/s

Took me a while to achieve stability (one of my cards is starting to get flaky - EDIT: or is there any chance memory errors could be caused by bad risers?) but this seems to hold for now.

Next up: The Vega's.

Wish me luck...

I would check the power connection... unplug it and check the connecter to make sure the connector hasn't started melting (a sign of high current draw)

Yeah makes sense. I haven't physically checked on this rig for a while now. But I've had a few melted power connectors in the past so I'll have a look.

I'd suggest finding a good soft power play mod.  You can really dial in wattage usage better than just power limiting in ntool.

I'm not powerlimiting on CN, just tweaking down voltage to match what the core clock is showing me for 100% PL.
Bearing in mind that Vegas are a pain (well, unless somebody can point me to a good, clear and up-to-date guide on how to tweak them), as memory voltage isn't displayed (HWINFO64 shows a static value of 1.356V), tweaking mem voltage in Overdriventool results in the core voltage being adjusted... So I find it very annoying.

And then these soft power play mods. I did find one that worked, but no fakking clue whether it's "a good one" or not.

tested your rig on wownero v8
driver 18.5.2 windows 10
wownero v8 --- r7 370 2g --985 / 1400 - i 30 -w 16 -k 1 --- 360h / s
monero v7-- i 30 -w 8 -k 1--985 / 1400 --- 475h / s
rx460 2g
v8 1216/1750 --i 25 -w 16 -k 1 --- 451h / s
v7 1216/1750 --i 25 -w 8 -k 1 --- 468h / s
r9 285 (380) 2g 928/1375
v8 --i 30 -w16 -k 1 --495h / s
v7 --i 30 -w8 -k 1 --- 540h / s
r7 260 x 2g 1188/1625
v8 --i 15 -w16 -k 1 --- 213h / s
v7 --i 15 -w 8 -k 1 --- 216h / s
  Pitcairn loses up to 25 percent of hashrate
against the rest of the cards
  Very surprised with the results of r7 260x

You are not quite right. The hashrate will fall for everyone in proportion, which means that all miners will receive the same amount of coins as before the fork.

hy

anyone test v8 with blockchain driver ?
want to know if i can stay on blockchain driver after fork

thx

Same amount of coins with more power consumption = less profit. Coin price would have to appreciate to offset loss from extra power.

Edit: Add'l consideration would be if there are FPGAs on V1. In that case, gpu miners might actually get more coins post-fork.

2250 core? Good way to blow up your 570    Probably meant 1250.

Sorry, Core 1250.

It seems that the newer asic-resistant algos have a tendency to use more power. CNv2, ProgPow... And then they wonder why the market for asics increases.

Edit: my vega rig draws 30% more power on CNv2 vs CNheavy.

That is not true.

Hashrate will NOT fall for everyone in proportion, if you have Vega card your lose will be higher than lose on RX cards.

I guess I didn't think about my future. All my rigs are 7x Vega 56/64 on a HP 1200 PSU and this PSU is 100% loaded. If new algo consumes so much more, I will have to dramatically downclock the cards, so I will not use them to full potential, or remove one Vega from each mining rig and build new rig, and that would really suck because I would need new rack as the present one is full. Fuck!

you don't use this cheater miner it cheat 30% less profit, go to jce low hash low power your 1200w enough

Another miner that I use is late to the V8 Vega miner party, so I am looking for alternative

How to reduce single RPM? I have 6 cards, all near 60 degrees, but fans one of them have much more RPM than anothers.

The thing is I have on every card same settings:

Fan_Min=300
Fan_Max=2000
Fan_Target=75
Fan_Acoustic=1340
Power_Temp=85

Damn thats a crazy high hash rate for XMR what mem strapps u use ?

[BS0D]

Vega 64 V8 (18.6.1 driver)
"worksize": 8, "intensity" : 123, "double_threads" : true, "persistent_memory": true, "bralock": 2
PPT + 1486/878 1100/878
2030 h/s

Don't actually understand what "persistent_memory" and "bralock" does but in some variants it give a less higher hashrate so I've left it here.
V8 really needs more power. It doesn't work with 875mV for me but with 878mV it seems ok.

[keksik]

What i am doing wrong?  i have same cards rx580 4/8g same settings:1250/950 // 2200/950 same memory vendor, left on auto intensiry and they hash very differently. One is 950 and second 790,other with only 2100memory ia hashing 1030,other withb same frequency 840,etc.
How do you test your maximum for each card?

So there is no way to get it to work with older AMD drivers like 15.12 ? This is on Windows 7.

Basically starting the start.bat or the SRBMiner-CN.exe results in an instant exit and doesn't even provide an error. Checked the log file and nothing was created.

put a pause at the end of the start.bat so it won't close the window and you probably have a parse error in the config file.

Yes i've already tried this. Its basically completely blank. No error or anything. And there is no log file created either.

I am using AMD Drivers 15.12 on Windows 7. Wondering if anyone else has been succesful in getting these to work somehow.
