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

[sorry2xs]

Need some advice

I need a couple of new cards i can get these 2

280x for 115 usd
470 for  220 usd

The 470 sounds like more future proof but getting like 180 sol
280x looks much better it can get like 210 sol

Ok, so it looks like everyone else is getting approximately the same hashrate difference for R9 390 vs. RX 480. I get 260 H/s and 190 H/s respectively with mine (both 8 GB). So my question is, is it expected that the 480 hashrate is only 73% of the 390? Is it because of the lower power consumption on the 480? With every other miner/currency so far, my 480s hash at about the same rate as my 390s. Is this something new with v8.0?

is that a problem?
after few hours appears incorrect data

this could be due to excessive overclocking or undervolting.

not overcklock, not undervolt, there is change bios
did not claymore 5, 6, 7 only 8

Try reducing the intensity. Use -i 5 or 4 or 3. The V8 stress the GPU more. I had the same problem with V8.

voltage increases on the problematic card
1,09 -> 1.15
problem again
2*7950 card
-------------------------------------
Now I reduced the intensity of 3

whats your wattage at GPU-z

85-90 W depending on card.
I posted screenshot already in this topic

my 380 read ~38 watts on gpuz, my 390 is at about 120w and my OC 390 is closer to 200w. it's on a gold 1200w PSU, running in an ambient temp of ~14c, near an open window, VRM temps of 10c at idle.

GPU-Z is such bs, look for at the wall readings.

No it is not. It is because 290/ 390(x) are high end cards vs 470 low-mid/ 480 mid level, amd has not released that high performance gpu yet.

470/ 480 owners were lucky to enjoy hig end hashing rates at one algo with some bios modding. Today ancient 290 hashes more than 470/ 480 with the same or better hash/ watt ratio, better get used to it.

ps. what where those every other currencies where 480 matched 390?

[mishka25]

After the v8, both of my r9 280x have died. Be carefull.

I don't really believe in coincidences... But I'm not sure. Maybe usage went up, and so did temps? Maybe they got hot enough to melt the solder, or something like that. I have a pretty aggressive fan curve on afterburner, even though my cards stay fairly cool. Around 75% fan at all times, or more if temps go anywhere over 80C.

I had same problem, it is thermopaste problem, i changed it and the problem was gone. temp went about 20C down.

you're more than probably right, I'm just too lazy to order an overpriced wattmeter online or take a bus across town to some sketchy electronic liquidator on my "day off". either way i'm clearly well within my PSU's tolerance margin, and my temps are cooler than ETH, so it can't be THAT far from the truth but being off by 15+ () watts is hardly accurate either. i can see my 390s being closer to those temps than my 380, no way it's under 40 watts, but there's no way its anywhere near 220 either.

While R9 serie has better hash, I don't quite agree about the hash/watt ratio. My RX 470 has better hash ratio than my 290x and the R9 is undervolted, not the the RX.

The R9 390's have more memory bandwidth (384 bit i believe) which makes them ideal for the Zcash mining algorithm. RX 480's only have 256 bit.

[Densitymax]

1xR9 290x 250 h/s 270 watt , 1xRX 470 185 h/s 110 watt. I think beter 2xRX 470 370 h/s only 220 watt.

Look at your 290x bios with hawaiibiosreader, pay some attention to those powerplay tables. Try those core speeds listed in dpm 2-7 + every combination listed in memory dpm 2-7.

Add afterburner -100mV or trixx -200mV and try what works best for you.

did someone have more than 189 h\s on ref rx 480 8Gb?

it depend on chance

390*6    1600 h/s    1030/1500                                 -60mv    1480W(gold psu) from wall (with -100mv 1300W)
480*5    1000 h/s    1288/2100 (mod bios 1750 straps) -60mv    850W(platinum) from wall
actually 390 works at -100mv, but to compare with RX480 I set Vcore to -60mv)

1480/1600 = 0.925 w/h (or 1300/1600=0.8125)
850/1000  = 0.825 w/h

so 390 better)

[FlensGold]

I get about 190-192h/s on the Sapphire RX480 Reference Cards (8GB).
My 4GB Sapphire RX480 Nitro+ do get 185-186h/s

Yeah, I've had that problem before, too.  I replaced some fans via ebay purchase for some 280x's and it shipped with some white thermopaste.  Tried it out.  It was total crap!  Replaced it with some Tuniq TX-2, wow, what a difference!  Never use the white crap from china, never.

I can get 295 s/s out of 390 without bios mod but there is no reason to push it to the limits when you can do 240 with -50% on power consumption.

512 bit actually

So I downgraded from a 16.x.x on my other rig (390 and a 380) down to 15.12 (finally got that to work...)

Increased my 390 from ~230 sol/s to 260 sol/s and my R9 380 went from 120 sol/s to 130 sol/s on Clay's 8.0 release.

So I'm fairly satisfied with that, and I'll likely just leave it be for now.

However, on my rig with two RX 480's, I seem to be getting "miner thread hangs, needs to restart" and then I need to reset it manually. Would a lower intensity stop that problem? I do use this rig while I mine, so maybe other things (like video playback) taxing the GPU is causing issue? Not totally sure. Maybe I'll just leave it alone and see if it still happens, who knows.

I can get 295 s/s out of 390 without bios mod but there is no reason to push it to the limits when you can do 240 with -50% on power consumption.

ok, add new info

480*5 900h/s  1145/2100 (bios mod starp 1750) -60mv 650w from wall
650/900= 0.72 best result)

and
i get 285 h/s on sapphire 390 1100/1500 -50mv but i dont know power consumption.
