I have been using all cast xmr versions for 1 year.. and i did not have any issue since v8 came up.. now i have installed cast xmr 1.5 .. when i get v7 requests , my rig does it without any problem.. but when i get sometimes v8, my rig is running 500-600 hash rate per card.. i have 5 vega 56.. whats wrong with v8? do you think i should add -1 switch?

On official site of cast xmr saying that there will be a %10 decrease but this is more than %70 decrease..

BR,

Hi,

this is a known issue (related to some mainboard chipsets?). The cure seems to install the AMD drivers version 18.5.1 (if that does not help version 18.6.1.).

Independent form the hash rate drop. Please use the "--algo=-1" switch or leave the algo setting out completely to make the automatic switch from CryptoNighV7 to V8.

I have just installed 18.5.1 adrenaline driver. Now my hashrate fixed to 1800 for v8 . Blockchain driver was causing the decrease of hashrate! . But now i am receiving for all v8 shares rejected . Reason: Share above target. I dont have any problem with v7. Is this a driver related issue? I can install Adrenalin Edition 18.10.1 Optional if you think it helps to get rid off "share above target" issue..

Thank you very much for your quick response..

BR,

Note: Soon i will install Adrenalin Edition 18.10.1 Optional and will inform you...

Note v2: seemslike it is a beta driver.. i had other stability issues.. and than back to 18.5.1.. now v7 is ok .. same issue for v8.. share above target..

is it still profitable to mine cryptonote currencies at current prices? I turned my rigs off 3 months ago..... Huh

Hi,

an Cast XMR update is available. Please update your miners before 18th October if you are into Monero.

Also there is now a Cast XMR for Ubuntu beta.

Regards,
Glph3k

Cast XMR Version 1.5.0 (2018/9/27)

- Support for the Monero V8 Network Upgrade which introduces a new CryptoNight variant CryptoNightV8 aka CNv2. The Monero V8 update is scheduled for 18th October. In case you are mining Monero make sure to update Cast XMR before that date. Also make sure that the algo for Monero is not explicitly set to CryptoNightV7 but set to auto detect with --algo=-1 to automatically switch from CryptoNightV7 to CryptoNightV8 when the upgrade is happening. Please also note that the CryptoNight V8 algo has added complexity which decreases the hashrate up to 7% for Vega GPUs.

Had computation error, i lowered Ram clockspeeds by 50 mhz , not related to core clocks.

worked.

So just a question, before i usually used HBCC and blockchain drivers on windows 10 (1600 or 1700 build win10 build) and i got around 1440 h/s in cryptonight heavy for RX Vega 56

But today, everytime i try blockchain driver i get around 1150 h/s and the adrenalin ones gives around 1290 but i found one that does 1320 and it worked across several windows builds.

My problem is that, is 1450 only for V56 flashed to V64? because im not flashed, i did test it a year ago but oh well it had a power issue where it kept increasing power whenever under load until it throttled during release month.

Which drivers are people using with RX Vega now and are you using HBCC ? Have you flashed V56? for Cryptonight heavy

Freakin noob. HBCC has never done anything and never will. What are you even talking about?

EDIT 9/29/2018 @ 8:07 PM CDT: This problem with very low hash rates is only on a HP Z400 System with an Intel X5660 processor. On my other system which has 4x Vega 56's and an Intel i3-4340 the hash rate is 7331 H/s for V8 and 7585 H/s for V7. So V8 is 96.7% of V7 or a 3.3% decline which is better than 7% quoted.

The Intel Xeon X5660 is a Westmere Microarchitecture whereas the Intel i3-4340 is Haswell Microarchitecture.

http://www.cpu-world.com/CPUs/Xeon/Intel-Xeon%20X5660%20-%20AT80614005127AA%20(BX80614X5660).html
http://www.cpu-world.com/CPUs/Core_i3/Intel-Core%20i3-4340.html

Cast XMR's Support for the Monero V8 Network upgrade which introduces a new CryptoNight variant CryptoNightV8 aka CNv2 is broken badly for Vega 56's if they are using CPU's from the Westmere Microarchitecture. The quoted 7% hash rate drop is actually 62.7% for Vega 56's.

I have just tested Cast XMR Version 1.5.0 (2018/9/27) on my system with 2x Vega 56's and the hash rate decrease is drastic as in 1442 H/s for V8 vs 3845 H/s for V7. That works out to be only 37.7% of the V7 hash rate or a decrease of 62.3% not the 7% stated.

I used --algo=10 for CryptoNightV8 (CNv2) and the killallasics.moneroworld.com:7777 port for testing.

On V8 I am only getting 1442 H/s on the two Vega 56's (715 H/s GPU0 and 737 H/s GPU1). While mining V8 the individual hash rates jumps all over the place from 847 to 568 on each card.

This also effects Pentium G4560 CPU’s as well hashrates on Vega GPU’s are in the 700-800’s compared to V7 1800 to 2000’s (depending on memory variant) something is seriously wrong here!

*!DRIVER VERSION MUST BE UPDATED!* I was on 18.4.1 and upon upgrading to 18.6.1 issues were resolved.

Did you ever think about running a separate mining instance for your crappy 570's or just throwing them away?

Dont have any options for that, but when this rig has been mining its basically been only mining on the rx580's and putting the rx570's under load doing ABSOLUTELY nothing and problem is that miner shows hashrate despite never giving new work.

Edit, did you mean running 2 instances of the miner? one with specified rx580's and one with rx570's? cause thats something i would try right now.

Yes that is what i meant. You use the -G command to run specific GPU's for one miner and the other.

Update once again, i know guys.

If miner detect RX570 + RX580, (2 rx570 + 5 rx580) the miner does not give new work to RX570.

RX570 flashed (even back to stock) is registed as RX580 name on new adrenalin drivers, Miner works, but you cant enable compute mode on the 2 gpu's, AND it usually Crashes atleast for me. Are there any settings i could use? Or known Drivers that work?

All this hassle because i bought two RX570's to my Mining farm. the other miners out there are garbage for rx570 / rx580 because they are dual thread, uses 25-35% more Power for 5-7% more hashrate.

Driver 18.5.1 crash stock rx570 bios
Driver 18.8.2 crash stock rx570 bios

Blockchain - Works but RX570 not given "work" by miner same with all that detects the gpu as rx570.

So i figured out the problem.

Custom bios RX570 4gb , is recognised as RX580 in new drivers, only two drivers when installing it shows as RX570, and those will not run (switch job to) on miner, they are basically sitting under load doing nothing.

With new drivers it detects them as RX580's, okay, but the problem now is that the RX570's cannot enable Compute mode, despite using tools and registry it only enables compute for the RX580's, the rx570's wont enable, it shows its enabled but in miner it shows disabled, pls dont like the auto compute enabler as reply to this.

So, with custom bios my rx570's will just run 570 h/s and i dont know what im gonna do really, put them back to normal bios and try that or just go with it and say okay well, its big chance that once miner see's RX570 and RX580 again it will not give new work to RX570 so its back to same as what it was with custom bios.

been testing drivers for many hours now.

the blockchain drivers detects them as RX570's so those wont work, and 18.3.4 detects them as RX570's, the old drivers detects them as that. Only the new drivers detects them as RX580's which works with the miner, but then you cant enable compute mode on the rx570 variants.

Hi,

a Cast XMR beta for Ubuntu 16.04 and 18.04 is available for download:

http://gandalph3000.com/download/cast_xmr-vega-ubuntu_149B1.tar.gz

It needs the latest AMD driver (18.30) installed.

Regards,
glph3k

Can you briefly introduce it? For example performance?

The performance should be comparable to the Windows version. The over clocking features of the Linux driver has still to be tested and documented. A proper release description is coming soon.

I've seen that case too, the miner never "switched jobs" for some 570s. no issues with other CN miner software.

recommend me a miner, those are nitro+ with hynix memory i think the issue is just 4GB cards not working with 8GB cards when you have alot of GPU's. my other righs with rx vega + rx580 8gb's, there all the gpu's are 8gb

or else its just rx580 8gb not working with rx570 4gb,
