    ok interesting, i looked into this a little more.

    I upped my frequency to -10 from -30. I will see if it's more stable. I was following the STAK reddit guide. Seems things evolved quite a bit.

    I'm fooling with 0% tdp. It costs about 150 extra watts at the wall vs. -20% tdp on 3 Vega 56. It's does not really matter to me. I have big enough PSU, I just want stability. Profitability is about the same, all I want is good stability. I'm curious why the virtual memory settings matter...

    I switched back to the Vega 56 BIOS as I see ZERO reason at this point to upgrade. Even though you can up the Memory Freq past the 56 BIOS (stable) limit of 935MHz, there seems to be no real gain in any way, and in fact, power usage seems to go up compared to stock 56 BIOS.

    My current settings with 56 BIOS @ 1942.9 H/s Average @ 68C Temp:

    GPU: Freq% = 0
    Memory Freq% = 935 MHz
    Power Limit: +10% (However this does not seem to make a difference weather its 0% or 10%)
    FAN: 2000 RPM

    THIS SEEMS TO BE IMPORTANT!!!!!!

    Disabling and reinstalling the Vega 56 in "Device Manager" after any Wattman changes seems to add a level of hash-rate stability, though I might be imagining things.

    if you aren't going to flash the BIOS -I can't for instance- and want better temperatures I'd wholeheartedly recommend you to read my post on the matter of Vega 56 settings and bat files and Windows restarts.

    https://bt.irlbtc.com/view/2256917.1200

    If like me, you can't flash the BIOS -or maybe you prefer not to-, dont mind the comments saying that's unnecessary 'cos it makes a hell of a difference and your life easier and you can have a 24/7 rig without hash errors at all, low power consumption and a totally automated process at every restart -say your computer is powered off- without you touching a single setting!

    This guide is excellent to start.

    http://vega.miningguides.com/

    btw pyr8, those temps are a bit in the unacceptable side. A number in the 50s or less is ideal.

    @almost30 that pace seems ok. What's your simple Vega hashrate as of now? You'd get around .84 Monero with that speed in 8 days, and in less than 2 days the rest to get 1 Monero. 10 days = 1 Monero with 6 Vega sounds like a quite good hashrate to me.

    What does it mean Avg Job Time ?
    Because this number is too big in my output.

    [09:39:14] Shares: 3624 Accepted, 2 Errors | Hash Rate Avg: 11781.7 H/s | Avg Search Time: 13.2 sec
    [09:39:15] New job received. Avg Job Time: 20812.6 sec

    Where I can send issues? To this topic? Miner app will sometimes freeze.

    Thanks.

    I see here that many people claim to get 1950 Hs with memory speed of 945 or so. I'm wondering what i'm doing wrong - i'm also getting 1950, but with memory at 1100 (and gpu at 1407). If i set memory to 945, hash rate goes down to ~1700-1750!?

    I'm using Vega 56 cards, with 64 bios and registry files for HBM1100. And of course, blockchain drivers and latest version of Cast XMR.

    P.S. i have 6 cards, tried with single one and same result. I'm also using only 2GB of RAM, not sure could that be an issue (but i doubt, as all calculations are done inside GPUs).

    thanks

    Hi guys,

    I was wondering since your software supports Vega but also polaris, why not allow for older cards like Hawaii? (r9 390/X & r9 290/X)

    I own this card and search for the best software to mine with Smiley.

    Sad to see it doesn't support R9 390X. Great card though (modded bios to lower consumption).

    Merry Christmas & Happy new year to all of you!

    well, you modded the BIOS, that's the most likely cause. For instance, I can't mod it because the cards in the rig arent mine. But the 6 Vega 56 GPUs rig whose owner wanted me to build for him are set up to run at 935MHz, with OverdriveNTool -I dislike AMD Wattman, it's enough having it on my desktop computer every single day- managing the settings.

    At 935MHz the unmodded Vega 56 mine at around 1940H/s with 100% stability (= 11600-11700H/s all of them combined), which in the end is what makes the biggest difference. @commonrnx shared a couple of very interesting videos on modded Vega 56 cards.

    I have no experience with modded cards but the settings are ok for a modded Vega 56 GPU afaik -Vega 64 HBM can run at higher speeds, which is what a modded Vega 56 achieves-, 'cos they run at Vega 64 speeds, just with lower consumption. Maybe someone who has modded Vega 56 can help you more concretely.

    Thanks, I've been running stable all morning at 935MHZ on my unmodded 56's.

    I'm at target temperature of 60C
    Fan minimum at 2500RPM
    TDP 0

    Fans are not roaring with these settings but hover around 3000 rpm

    I like the big numbers at 0 TDP but there is only a $0.03 gain per day at my electricity cost for the extra hash.

    Anyway, all that doesn't matter. 935MHZ seems to be the sweet spot for me with CAST XMR on unmodded 56's.

    I save about 47 watts per GPU at the wall moving from 0 to -20% TDP. When I run lower I can set the fan minimum to 2000 RPM and target temp to 60C and fans hover around 2500RPM. That's better for me. I'm so over the ridiculous fan noise.

    Hm, sounds strange to me, as i though vega64 bios is used only because of better undervolting and overclocking possibilities. Instead in relative percentages, do you know exact frequencies of GPU at those settings? I'm most interested in lower power consumption (150W) and getting about 1900 Hash/s is just fine to me. Even if cards doesn't complaint about 1100mhz, i believe they will be more relaxed on 945MHz.

    And just to be clear, you didn't even change registry for voltage adjusting, just using installed drivers/cards with factory settings?

    Btw, is there any explanation of intensity argument, and how to find the best one for the card (except trying all 10)?

    I've never understood the above - I'm able to get 2000H/s on my Vega 64 @ about 150 watts, no bios tweaks, no reg edits.

    1100MHz memory clock.
    -30% core clock.
    -30% power limit.

    The only reason I'm mining VTC instead of Monero is because the beta blockchain driver is dogshit and keeps having "hiccups" that drop the hashrate to 1700~ until the card is restarted.

    I really wish the OP would allow the full speed on non-beta drivers, they're antiquated and unnecessary now.

    How many will RX VEGA cards work in one system?
    I was planning to buy 13-card based board or even 19-card like Asus Mining Expert but I don't know if it will accept them.

    Most folks that have posted about working with more than 4 Vega in one system have said it's a nightmare when it DOES work - and I have yet to see ANY posting of more than 6 actually working.
    I'm no longer legendary just in my own mind!

    Hi guys.

    I have a problem with my vegas.

    I have a MSI z370 PC PRO motherboard and 2 vegas plugged in.
    With only one vega connected i hace no problems at all. works fine.
    But when am trying to connect the second, and start mining with the second i got a crash when i start cast xmr.
    When i am using a only one vega AMD settings shows normal, if 2 vegas are connected, HBCC memory option in amd display settings just disapear.

    1st vega is connected to PCI-E x16
    2nd vega is connected to PCI-E x4

    iI have more PCI-E slots, but they are mini PCI, and i need a riser in order to use them.
    I have tryied to change in BIOS settings enable minngng, but am still having the same crash when 2nd vega start mining.
    Do you think if I buy a riser and connect the second vega to a mini PCI, can solve the problem?.

    rest of my specs are:
    i5 8600K
    SSD 250
    16 gb ram
    2x vegas 56

    Thanks all!!

    According to AMD, all of the features that benefit compute workloads are already enabled by default in Vega's architecture, so the switch isn't necessary. It's basically for other RX GPUs.

    So I've just flashed my 56's to 64 vbios and applied Hellae's "safe" reg file.
    I've set some new frequencies in OverdriveNtool but CastXMR just keeps stopping on me after a few minutes. Does that mean I'm not giving the memory enough juice? Too much clock? Is it core related? Can anyone who's been through this help me troubleshoot the behaviour of the miner please?

    Edit: up until it stops, the miner reports 0 errors, if that's of any help...

    Edit2: increased the hbm voltage a notch and it seems to be mining for now... Current overdriventool file looks like this:
    [Profile_0]
    Name=Vega64
    GPU_P0=852;900
    GPU_P1=991;900
    GPU_P2=1084;900
    GPU_P3=1138;900
    GPU_P4=1150;900
    GPU_P5=1202;900
    GPU_P6=1212;900
    GPU_P7=1376;905
    Mem_P0=167;900
    Mem_P1=500;900
    Mem_P2=800;900
    Mem_P3=1050;915
    Fan_Min=3600
    Fan_Max=4900
    Fan_Target=75
    Fan_Acoustic=2400
    Power_Temp=85
    Power_Target=0

    Getting approx 1850h/s/card, total 1050w from the wall (6 GPUs).
    Any suggestions welcome!
