Topic: RX 560 hashrates - page 9. (Read 28007 times)

Hello! I finally found the owner of these cards in Linux
I am very happy. I ask you to share your bios for the results. Which miner you use and what settings? In ethOS my hash does not exceed 430 h/s.

Those are some nice numbers, i finally figured out how to edit the bios straps for my 7950's, and i did it, but tbh i dont notice much more hash/s.
i bios edited 2 saphire 7950's and the 3rd 7950, a club3d 7950 wich i didnt mod yet, actually does more hash.
2morrow im gonna try to biosmod my rx460

I have this Memory on a AERO ITX 560 4G SK Hynix H5GQ8H24MJR
still testing but so far:
OC: CORE 1167 DPM 3 V925 MEM 2200 (I Have to set 925 for stability but an other card seems to be stable with 900)

Hash: 473H/s on Cryptonight ~ 28W on amd-info (use HiveOS) All machine (CPU/USB key/...) Less than 82W
Hash: 15.5MH/s on Ethash ~36W on amd-info All machine Less than 93W


 

Can I damage my gpu with memory errors? I get cca 40 of them in an hour. No rejected shares. It's Elpida memory.

If that's a question, then no, I didn't measure the power consumption yet, got only one of those killawatt devices and it's currently not at the same location as these rx560 rigs. I'm curious about the consumption myself so I'll try to measure it in ~ a week.

I've got the following cards (all 4gb): gigabyte oc rev 2 (single fan, 14 CU), gigabyte gaming oc rev 2 (dual fan, no aux power), msi aero, asus strix o4g (aux 6pin power), asus strix o4g evo (14 CU, no aux power), asus RX560-O4G. All 14 CU cards unlocked to 16 CU, and they all came with Micron VRAM (not sure which chips exactly, the bios says it's MT51J256M32HF_60S). All 16 CU cards came with Hynix VRAM. Two types of Hynix ram mentioned in the BIOSes —H5GQ8H24MJR and H5GC8H24MJR. Out of 16 cards I've got, the three Asus 16 CU cards are the worst (two Strix and one regular O4G): their stock memclock is 1750, but all three show memory errors in HWInfo even at this stock clock! And that's even with the stock timings. First time I see something like this. Tried to google this thing, found this thread: http://www.overclock.net/forum/67-amd-ati/1636308-problem-memory-rx560-cards.html
This could explain why I'm having this trouble with Asus cards, they probably installed cheap 6 GHz memory chips on their cards, but set the clock to 1750 MHz in BIOS.. which kinda works, but not really stable = producing memory errors in HWInfo. Lowered the clocks to 1600 MHz on these 3 cards for now, 0 errors so far.
For Micron cards I'm using this strap: 777000000000000022AA1C00315A5436A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715
And for Hynix cards — this one: 777000000000000022339D00CE515A3D9055111234CC440900400600740114206A8900A00200312 01E0F292F94273116
Getting very similar hashrates with these. I could test some other timings.

Was it this type H5GC8H24MJ? What timings are you using? Would you test my XMR timing for that?

you used a kill a watt from the wall for calculate exaclty the power consumption for

If you mod the 7950 BIOS with a hexeditor, you nust recalculate the checksum of the BIOS !
I don´t know why, but the 2gb RX 560 version is faster in xmr, than the 4 GB version.
I also had unlocked the 2 extra CU´s from a RX560D ... it´s slower than before and need more power. 

Yep, I think there are no editors for Tahiti cards, so hex is probably the way to go.

Well, I don't think there's a lot of people out there hashing at 500 H/s with their 460/560 cards. It's certainly possible, but requires very good memory/timings, or serious overclocking. I've only built a couple rigs with these cards so far, and didn't do any fine-tuning, so could probably improve my results — at the moment my cards are hashing at ~ 420-425 H/s, all running at 1100/[email protected]. Cryptonight profits have gone down quite a lot, so I guess I'll be switching to ETH soon (where they do ~ 13 MH/s each).

Ya im sorry i wasn't being precise, i have a rx460 that i flashed a bios on so the 2 extra cu's are already unlocked.
I think i will be able to mod the timings on the rx460 with that polaris bios editor, it looked easy

But i also have 2x 7950's, wich after i read this thread, i also wanted to mod the timings on, this is how i ended up with the hex editor.
I found a topic on some forum where someone explains hows to do it, im gonna try it tomorrow, aftwer that ill do my rx460, it only does 320h/s on cryptonight and i see people in this topic reporting 500 hash.

Im also wondering, in etherium you cant mine with rx460 2 gb, you need 2 gb, how is this for equihash? you mine faster with 4 gb vs 2 gb or it doesnt matter?
And for cryptonight? i heard cryptonight uses memory so does a rx560 4gb do more hash then a rx560 2gb?

You'd need to use a hex editor for something like unlocking the 2 extra CU in the 14 CU version of RX 460/560, but for most other things (including voltages and timings editing) there are simple GUI programs that are very easy to use. At least that's the case for Polaris-based cards.

Hi, i really didn't want to look like some lazy guy, i've been figuring out how to do it all day ( litterly)
Read some russian tutorial and i feel like im close to succes, but i just cant figure out how to copy paste the desired numbers into the hex editor.
Thanks for you link, i'm gonna try that out tomorrow.

There's ~ a billion guides on how to edit and flash bioses for AMD cards out there. Plenty of software gui tools that allow easy copy/paste editing. Here's one such guide: https://bitcointalksearch.org/topic/guidetutorialxmrethhow-to-mod-bios-rx470570480580-vega-mining-1954245

Ok, thank you.
I tried to edit my mem timings in Hex editor, but i cant figure out how to copy paste the new code into the old code, i have to type every digit 1 by 1 and its not working, brainexplosion, and im scared to brick my gpu it has no dual bios.

Not really, but they might be very good on both. However for the best performance you need timings optimized for XMR or ETH.

About the memory straps, if you found a good strap for say ethhash, will this also usually be the best strap to mine for example cryptonight with it?

With compute workload you can set higher intensity and you will get slightly higher hashrate. But all my AMD still run on 17.6.2 drivers

All is the best
but, Asus ROG is my favorite

What timings are you using to get 280 H/s? I don't think drivers matter all that much for cryptonight, it's essential to get ones with "dag fix" for Ethereum mining, but not that important for anything else.

The blockchain drivers didnt work on my 7950´s, and on the andrenalin drivers only 30 hash, on 15.12 drivers i got 280h/s
