Claymore's CryptoNote AMD GPU Miner v11.3

Why your miner see only 3072M of video memory on R9 270X 4Gb card?

The same situation with graphics cards r7 370

The same situation with graphics cards r7 370

cause you are both stupid enough to disallow 64 bit gpu pointers
you should
setx GPU_FORCE_64BIT_PTR 1

On my R9 270X with 4Gb in bat-file exist string
setx GPU_FORCE_64BIT_PTR 1

but miner shows that GPU with 3072M video memory.

Well you're one smart. Installation setx GPU_FORCE_64BIT_PTR=1 helps, That much I know. But it is impossible to achieve the maximum memory values with the parameters -h and-dmem

setx is used without equal (=) sign.
= is used with set command, e.g. set GPU_FORCE_64BIT_PTR=1

And what problems with -h and -dmem?

[treanski]

I'm able to get about 760-790 h/s with 10.2 on my cards.  Mix of RX 570s/580s 4GB.

On a 580 8GB I have it gets slightly above 800 h/s but thats about the best I can get so far.

If anyone has gotten higher and have any tips let me know.

Thanks

On my RX 580 8Gb(hynix) 1380/2200 I can reach 840-850 h/s -h 1800 -dmem 1
There is some peoples have 1k+ h/s on 480... I don't know how.

with ubermix 3.1 straps and samsung mem

I didn't rtied ubermix straps on my hynix memory. It's possible that they are will work on hynix memory?

No, please do not try to use memory straps from SAMSUNG memory on HYNIX because you risk breaking your card.

I'm not 1st day works with computer parts. And I know what is memory timings. Not only on VRAM. And I know that they are can't make damage on card, it can't even damage video memory. Maximum that wrong timings can do - it's BSOD or system hang during initialization of video memory on frequcency were timings are modified.
And you must know that almost half of modified straps in the internet for hynix, elpida, micron are maked by modifying memory timings from other memory.
F.e. best memory timings for RX 580 8Gb with hynix that you can found in internet taken from 1750 micron memory strap of RX 480 8Gb without any changes.

what is the hashrate with the micron straps?

That strap used in all modded bioses for 580 cards with hynix memory founded in inrenet. It gives about 29M speed on ethereum. 840 h/s on monero.

If i set set GPU_FORCE_64BIT_PTR=1 -dmem 1 -h 896 i have 502 h/s, if set GPU_FORCE_64BIT_PTR=0 -dmem 1 -h 512 I get a 530. That's the problem.

[UnclWish]

It's the best available for everyone that can be found in internet. I think that it not the best too. But I can't find better...

The -h parameter for 270/270X/370 is 512 the best. You can check it by launchung without -dmem 1 option.
-dmem 1 option is increase a little speed on these cards. But if -h parameter optimal without -dmem 1 option than it will be optimal with -dmem 1 option.
530-540 h/s is the maximum for these cards i think.

Setting -h as high as possible is good only for modern Polaris and Vega cards (don't know about Fiji) with blockchain drivers.
For older cards (hawaii, tonga, etc) you should find the sweep spot. And it won't be the max value

Nice results. Does overclocking parameters work or I should use afterburner?

[kirilvvbg]

New 10.2 is not good for all cards, it seems...

Just tested on my old Pitcairn R7 370 2GB
On v9.7 - 490-495 h/s
With new 10.2:
- if I start directly default -dmem tries 2.5+ GB of memory - obviously it doesn't work and miner gets stuck
- if I disable -dmem (-dmem 0), the best I can do is -h 832, but in this cases the h/s are only 475-480 (btw, Claymore - GPU0 must stay at -h 480, otherwise it crashes; but still gets these 480 h/s).
So it's not an improvement, but the opposite...

Unfortunately, good features and info of v10.2 cannot not be used... I'm sticking with 9.7...

And 10.2 became very sensitive to overclocking. On my 270X 4Gb on 9.7 i have 490-495 h/s, on 10.2 with the same frequinces and -dmem 1 I have 530 h/s and many of incorrect shares. Try to reduce OC and have only 515 h/s almost without incorrect shares.
If I disable -dmem 1 setting it to 0 then I recieve only 480 h/s with the same -h 512 and OC parameters that on 9.7 gives 490.

Sapphire Nitro+ RX 580's - 6

Current Cal Hashrate (Nanopool): 6,300.0 H/s (or 1050 per card)
Claymore output: 5140 H/s (avg 856 per card)

Coreclock: 1380 (if I try for 1390 it hangs)
Memclock: 2250
Power: ~115w per card
-h: 1800 (default)
Temp: 58-60c
Drivers: Blockchain beta

Changing the -h flag in any way (other than the default of -h 1800) provides worse results or restarts. Attempting to set voltage control hangs/bootloops. I had to set my core clock lower with v10.x.

For comparison, when running 9.7 I would get would get average of 5009 H/s, ~129w /card, temp 62c with
Coreclock: 1425
Memclock: 2250
-h: 2030
Mem and core volt: 875
Power: ~129w/card
Temp: 62c

Some things to check.

- One of my rigs started using 3,5 GB of ram. Closed the miner and it dropped to the usual 420 Mb.
- On another rig one GPU dropped to 0 and another GPU dropped to 500 (RX 470 usually working at 750-770). Restarted the miner also.
