 And as someone that's actually worked with the code, would YOU say there is much room for improvement for the RX series over the current code?

i have some rx470 4G with custom bios for ether, memory at 1940
but i notice is run faster with memory set to 1750

With a stock XFX 280x I get 471 h/s. With a Sapphire tri-x 280x I get 490 h/s. It corresponds to the calculator, but still... Judging from the lower power consumption compared to other Claymore miners, I feel that there is a room for 10-15% optimisation. I didn't try wolf miner but according to http://monerobechmarks.byethost5.com/ the speeds for both miners are (may be) similar. At least for 390 and 480 series, because for 280's the info is scarce.

I agree. Not the results at 2000 h/s. And 1500 is not. But to optimize for the new driver can be and will be the stability that is lacking now. In Zcah was an increase from 200 to 240.... So that a stable 800. And I agree - RX480 even weaker than many R9. Really the purpose of issuance, a new generation of energy efficient graphics cards!

 The RX 480 has FEWER cores than the R9 290, though it runs them at a somewhat faster clock rate.
 It has quite a bit LESS memory bandwidth, which for XMR is CRITICAL as XMR is a memory-hardened coin (more so than ZEC, more comparable to ETH).
 Specifically 256 bit wide 8000 Mhz for most of the 8GB RX 480 vs 512 bit wide 6000 Mhz for most R9 290 cards, so 2/3d of the memory bandwidth.

 Compared to the R9 280x, it is the SAME number of cores at a somewhat higher clock rate.
 It STILL has less memory bandwidth (though it's CLOSE here for most of the 8GB cards, 256 bit wide 8000 Mhz vs 384 bit wide 6000 Mhz for most R9 280x so only 8/9th of the bandwidth).

 Even the REFERENCE R9 280x at 5000 Mhz has almost identical memory bandwidth to the RX 480 8GB cards.


 The RX 480 is NOT going to achieve 1000 h/s on XMR (barring nitrogen cooling for INSANE overclocking).
 In FACT, I suspect the current XMR miners are already optimised about as well as they can be for the RX series.


 Be happy with your major hash/watt improvement over the older cards, they're ALREADY MINING "full speed XMR".



 I have no horse in this game on the AMD side, the only thing I have working on XMR at this point is a pair of GTX 750 Ti cards.

Listen your RX 480 won't hash at like 2000 H/s with XMR. Its pretty much very similar in speeds to a 280x - 290. Only difference is that it uses much less power.

If you don't believe me compare gaming benchmarks with a RX 480 and a R9 290 and see what results you get.

Just because your GPU is newer doesn't mean its faster, its the same speed just uses less power. No idea why so many noobs don't understand that. They keep complaining on the ZEC Claymore thread almost everyday.

NEWER DOESN'T ALWAYS MEAN FASTER!

I anyone having problems with this miner on a PC that is used for basic browsing? The miner is a bit outdated so I understand it won't be perfect for the 480's.

My PC is running:
6700K CPU (5% Usage)
16GB of RAM (30% Usage)
2x MSI 480 on Dwarfpool (100% Usage, Stock Cards)

The problem is, every once in a while, the hashate of both of my cards will drop from 700 to 500 and stay there. I have to restart my miner a couple of times and it will jump back to 700.

I also have issues randomly with errors:


Oh yeah, I also discovered that f.lux causes issues at times with the PC with the miner running. I assume it has to do with too much GPU usage from Claymore's miner (Expected when running at 100% utilization). My mouse would freeze up for a half second every couple of seconds. Just a note for anyone running f.lux with their PC.

EDIT:

I had taken f.lux out of the equation fairly recently so my guess may be that f.lux might have caused the issues. I will try without f.lux for a bit and see if that sorts the problem. Will leave my post up in case someone else runs into the same problem and stumbles upon it for future reference. Took me about a week to realize it 

yup exactly!  newmz got quite lucky that his old cards were good for mining ZEC, now he wants those of us with newer cards to effectively be punished by Claymore not updating this miner?  Man, talk about sour grapes lol.  But all is not lost newmz... you can keep on mining ZEC until it falls to $5 if it makes you happy to see those blazing hashrates lol.

not normal. I have error on start memory clock more than 2,100. In this case, the GPU 1300 MHZ. I Maini on MinerGate




 

And you were exactly one of them. You used your old cards to mine ZEC, and know you dont want other people enjoy full speed XMR?

Personally I hope Claymore leaves this miner just the way it is. The massive influx of RX card miners pretty much destroyed ETH and ZEC mining because so many RX noobs joined in with their gaming/mining rigs and drove difficulty way up (in the case of ETH) and drove the price crashing down (in the case of ZEC) by all the massive dumping on exchanges.

I'm really glad to have something to keep mining with my 290s, 290Xs and 390s.

So Mr. Claymore - please don't try too hard to make it easier for RX card miners, you will just flood the XMR network too! This is the last one left really. If you want to raise the dev fee a bit to leave it alone - I will personally be glad to pay it!

this error is because u r mining with xhchange wallet address
if u mining with xchange address than u have to put walltet address+payment id

example NsGpuCNMiner -o stratum+tcp://xmr-eu.dwarfpool.com:8050 -u AAAA.BBBB-p x

aaaa= address
bbbb= payment id

Hello everybody. Prompt gives this error. Purse with Exchange is the problem?

hello lads, i am getting  2038 H on 3x RX 480 8GB on 1250/2000. is it ok? in the same time i am getting Error in server response......"low difficulty share" failure msg coming al lthe time. any1 an idea?

my bat

setx GPU_MAX_ALLOC_PERCENT 100
NsGpuCNMiner.exe -o stratum+tcp://xmr-eu.dwarfpool.com:8050 -u poloadress.paymentID.1 -p x -a 4 -h 1024


am i doing smth wrong?

unfortunately while((

At 750 h/s on an RX480, unless i'm mistaken, we're already at the top end of what is achievable while being stable.

threw again



I agree. Waiting for it for 16 crimson!

This is my result
