Try dual mining

hi guys.
i hv 2 different brands of rx560 both 4gb.
HIS RX 560 GREEN iCooler OC 4 GB and (hynix)
PowerColor Red Dragon RX 560 OC 4 GB (micron)

fresh win10 1703
blockchain workloads aug23 driver (tried aug11, crimson 17.9.1)

ive tried copying various timing straps, 1500 1625 1750 1875 2000 and even try editing bios from other users tht was able to get 14-15mhs ive even tried Branko's micron bios, also tried the polaris 1.6.2 oneclick timing patch, the results i get is the same, max 13.6mhs, i can even reach this with stock bios on the HIS gpu @default gpuclock 1196 and @ 2100mclock. now im running the HIS gpu @ 1625 timing straps and 1900mclock and get around the same hashrate as default bios, and if i go higher mclock then its not stable. am i missing something? and should i leave the TDP TDC and max power limit or should i chg it to 60 80 80? does it affect the hashrate?

and the 2nd issue im having is not getting the actual hashrate when i run multi gpu (6pin usb risers). only one gpu hash normally at 13.x and others 12.6mhs. is it due to my old core2duo lga775 motherboard? power is sufficient. if i try only 1 gpu at a time at different pcie slots it will hash normally. but when i run all 4 only 1 will and other 3 will hash slower. should i edit the pcie voltage +0.01 0.02 0.03 in mb bios 
dag creation time is 95xx ms and  107xx 107xx 107xx ms

also anyone using sapphire rx480 8gb ref model(single fan)? a friend of mine wanna get rid of it at a good price wondering should i get it. shouldnt be a problem getting 25-26mhs? but maybe high temp?

thx for reading guys ive read thru alot of old posts and still not able to figure it out.

26.5 isn't terrible but you could probably get another 1 or 2 with some tweaking.  Many cards just can't reach 29 or 30.

If it's power draw in GPU-Z that's not so good. 26.5MH/s for RX 480 is very low.

someone mod can reach 15-16 MH

You have to mod your BIOS...and really no reason to put core that high

For now ETH is still about the best if you have 4GB.

None I'm familiar with.

If not mine eth have other better coin for rx560?

This website's information is inaccurate. You can check with claymore miner in benchmark mode where will the DAG file generation fail. Mine failed at DAG #176 and I have GTX 1060 3GBs , which will be ruled out sooner than I though.. about 9.6 months from now if I did the math right.

This website shows that 3GB cards will drop at DAG #256 which is not true.

Also it is worth mentioning that DAG allocation is a matter of software configuration. What I mean is that each vendor decides just how much his Video card model will allow its memory to be filled to full capacity. At dag 175 my cards were about 2650 MB used as per MSI afterburner. Which means that in theory they should be able to do DAG 176 as well (very small MB difference maybe 20-30) but they can't, because they have some small reserve that has to be left (I guess) The card that had the monitor on it had 2800ish of its memory used so I guess it is the culprit (if one fails maybe all fail)

Where do you get these numbers, cause according to the actual statistics for musicoin and how often it changes DAG it will hit DAG 95 which is the last possible DAG for 2GB cards around July of 2018.

Musicion will hit 2GB barrier at 11/FEB/2019, expanse will do the same in april 2026

Best I can achieve is 13.8 with my cards. As I said before it is luck of the draw. Maybe perhaps it is due to their being lower powered then your cards as I do not have supplementary power on them.

Well, your comment about bad micron and at same time much cooler outside temperature than during august made me try to push micron a bit further:

(accidentaly pushed ctrl+ break instead ctrl + printscreen, so real frequency was 2300, not 300 )

not much gain over 2230, interesting...one bad thing with micron is that it demands about 1200MHz core to go over 16MH/s

So about 15.8MH/s seems like a sweet spot

ok lowered clocks to 850 but when I pushed 2000 and up locked up rig solid
Also just checked Music is at DAG 35

Ive put the mvddc to 850 for the 560's and I am testing out 2050 now to see if it is stable. will know better in 24 hour if it makes it that far, have cclock at 1150 and cvddc at 900 currently with dcri 20 I am getting 14.2 per card ethash and 32 per card lbr

Update: well that didnt last long card #4 crashed at 2050 memory clock

Ive got an old PC box (Pentium, socket 775, 1GB ram, 200gb HD)

Buying a new PSU, 600/700watt and 3 RX 560 cards... leave it in the garage plodding away? not bad for the price me thinks with a few clock tweaks

24...it will take forever to get to 2GB

I believe every epoch is 30,000 blocks and it takes 14-15s to solve a block, So that is a new Epoch every 4.8 - 4.9 days. 60 epochs left till DAG 95. Therefore Musicoin should be mineable on 2GB cards for another 291 to 312 days
