clasic vega 56 powercolor with 64bios  in hevy : gpu=1442mhz 905mv  and mem= 1095mhz 900mv  = 1500+ HR-samsung
saphire nitro+vega 56 with 64 bios in hevy : gpu=1427mhz 920mv  and mem= 1010mhz 920mv  = 1420 HR (and block)-hynix
nitro take more power for smaler HR Sad

Any have  nitro vega 56? overdrieve setup? and HR in hevy?
1420h/s in Heavy is good for hynix memory. It has lower o/c capability and worse timings

Sad

now i have 1450-1460HR on hynix vega56/64nitro+: gpu= 1437mhz 920mv   mem=995mhz 905mv

nitro sucks:(. powercolor with samsung have 1600HR with 1452 915mv    and 1100mhz mem on 905mv.

hynix block on 1020mhz:( BAD BaD - and he call this card NITRO. NITRO sucks:(

It is a lottery, you can get hynix with any vega56 card except reference ones.
What have you changed to have more hash with lower clocks?

yes . lower clock more hash Smiley now i have 1470hr gpu=1437 920mv mem: 1000mhz 905mv.
i try gpu=1437 920mv mem: 1010mhz 905mv. but hr is 1450
and i try gpu=1437 920mv mem: 995mhz 905mv. hr is 1445
best for me is 100mhz 905mv memori
no i go chg gpu freq and voltage

but

kernel 3 and 4 is for old old cards, with 1024 and 512 mb ram.
Altough it should work on every card. Which algo are you trying?

Hi Doktor

Am facing a strange problem, I have two RX 570 4gb 8 card rigs with Samsung memory.

One Rig is running with very good hashing speed. the second Rig am getting an error

Error CL_INVALID_BUFFER_SIZE when creating scratchpad buffer for DeviceID 0 (Thread 0)


Card: RX 570 4GB Samsung memory

Error:  Error CL_INVALID_BUFFER_SIZE when creating scratchpad buffer for DeviceID 0 (Thread 0)

Any IDEA how automate ON HBC memory on vega?

ON start rig automatic:
1.disable and enable all card (devcon.exe disable "PCI\VEN_1002&DEV_687F")
2.Run OverdriveNTool.exe (OverdriveNTool.exe -r1 -r2 -r3 -p1profile1 -p2profile1 -p3profile1)
3. start srbminer

but HBC not work and HR is 1300 not 1500 on hevy adn i must stop miner  start srminer  intesity 60 close miner and start miner 56 intensity.

Any IDEA?

i use this in config file for v7 normal:

(for vega 64 ref)

"gpu_conf" :
[
   { "id" : 0, "intensity" : 112, "worksize" : 16, "threads" : 2},
        { "id" : 1, "intensity" : 112, "worksize" : 16, "threads" : 2},
        { "id" : 2, "intensity" : 112, "worksize" : 16, "threads" : 2},
        { "id" : 3, "intensity" : 112, "worksize" : 16, "threads" : 2},
        { "id" : 4, "intensity" : 112, "worksize" : 16, "threads" : 2},
        { "id" : 5, "intensity" : 112, "worksize" : 16, "threads" : 2},

]
}

overdrive: p7 1475@960  and p3 1100@980

i get between 2000 and 2040 h/s

Hi, you should to increase virtual memory page file, I have 6 gpu's installed, four 470 4gb  and two 480 8 gb -in such case around 31GB swap memory used

You are probably trying to run 2 threads with > than 50 intensity on 4gb card. It is not possible

It depends on your card (memory, quality of cooling, including vrm and memory cooling, power supply system).
In fact old samsung based rx480 and rx470 cards are very good (not mention power color red dragon crap without memory cooling)
Old hynix and old micron rx480 and rx470 cards are not so good as modern rx580 and rx570 cards with the same memory manufacturer.
Moreover, old rx480 seems can handle only 1100-1140mhz gpu clock @ 900mV but new rx580 can handle 1200-1240mhz with the same voltage. New revision boosted stable gpu clocks by ~100mhz

Guy, am I missing some settings, or in general RX4XX is slower than RX5XX?

the main differences are 8 gb or 4 gb, then your memory straps, then core / mem speed and the intensity settings...
(my rx480 gives 740 h/s on heavy, but it is a 4 gb elpida, my rx580 1110 h/s but 8 gb hynix)
