hello,

since ETH is worth mining again:

how can i manage to switch my Vega Rig between CN Algos and ETH?

i use PPTable and OverdrivenTool to set GPU & Mem for Cn Algos..but if i want to switch to ETH i have to lower Core Clock to reduce power Consumption (and ETH didnt need that much MHz on GPU for good speed) - is there a way to switch on the fly without loading other PPTable and only load other OverdrivenTool.ini?

?? you don't need to load another ppt table. you can underclock the core to save on power on ETH. Both CN and ETH need as high the memory can go.

but i have PPT for CN with higher Core clocks than needed for ETH mining

so i have (or not?) to load other PPT with much lower p-states for ETH mining - i dont want to load other PPT and reboot every time i switch between ETH and CN algo

you can underclock using overdrive while still using a cn ppt.

figured it out with using phoenix first time...the voltages will override everything...but now i have to find stable mv again for each card Roll Eyes

but i thought that i will save more power...cn8 with 12khs need 1000W on the wall...fast try with Phoenix miner give me 240Mhs with 900W on the wall

Hey guys

whats your intensity setting with stak2.5.+ in amd.txt for cn_heavy on 64/56?

im only getting ~1300h/s per card with intensity at 896

Quote

{ "index" : 0,
"intensity" : 896, "worksize" : 8,
"affine_to_cpu" : 0, "strided_index" : 2, "mem_chunk" : 2,
"unroll" : 8, "comp_mode" : true
},

Im reading that people do nearly 1500h/s per card Huh

on v8 i use 1984 intensity

and do you use something else for cn_fast/lite?

Thx in advance for any answers.

My 6xVega64 use stak2.5.1, algo Heavy,18.5.1driver Only get 7.8K,. But use stak2.4.7,20170823blockchain driver,can get 8.3k,Why?

the same parameters: core 1408/900 mem:1080/900 powerlimit -20%

Anyone having issues with the new version of XMR-STAK? Having hashrate issues. Old version I'm getting around 11,500 ... New version I'm getting 7500.

I am running two Vega 56's on Windows and XMR-STAK 2.5.1 (v8) and averaged 4,500 H/s now running 4,100 H/s (with CPU)

Newer AMD drivers cause problems - I run Adrenaline 18.5.1
It helped me to increase AMD config 'worksize' to 16 and 'intensity' to a higher number such as 1904
When updating to XMR-STAK 2.5.x you need to start with fresh config files and tweak them after running miner the first time.

I stopped using power play tables since 18+ drivers. overdriventool is enough to achieve full hashrate at 165W with vega 64 and modified vega 56.
clock: set to 1600, voltage set to 850mV
mem: set to 1100, voltage set to 860mV
real clock is 1400 to 1500 depending of the card ; real voltage: 885 mV; shown in GPUZ.

4 cards rig is at 700W, system uses roughly 35W

This sounds like you still need PPT. Assuming a proper setup w/ PPT, actual voltage has historically *always* been lower than set voltage by at least 7-15mv, due to droop. A higher actual voltage vs what you set is exactly what you would have seen in the past w/o PPT, because your <=P5 voltages were fixed, and higher than your P6/7. Only thing is, those lower state defaults were usually much higher than 900-ish mv, so something strange is going on.

Also, a drop from 1.6 GHz to 1.4-1.5 indicates you are significantly off on your power vs frequency settings. Your card is being throttled because it doesn't have enough power, and sooner or later that will lead to instability. You definitely want to minimize that difference between actual and set frequency, by either increasing power, or reducing frequency. In the past, I've found that a proper ratio is around 1500 +/- 25 MHz for 900 +/- 15 mv

i notice something strange
when undervolting, at 900mv it use 115w in gpu-z for monero but if i add powerlimit -10 or -15 power goes up to 165w and the gpu clock drop a bit and hasrate also a bit, it also use more power at the wall

Sounds to me like you've pushed your card past some internal (or bios enforced) limit, so it's resetting to some kind of default.

that make no cense, why should it be lead to instability ??

powerlimit is made to limit lol, it s normal gpu clock get up and down, and for doing monero no need full speed but going below 1350 decrease the speed

Because throttling is a reactive behavior, and it is not instantaneous. There's always a chance that between the threshold exception and the throttling reaction that the hardware gets into a state from which it can't recover.

And not sure how powerlimit came into this discussion - we're talking about voltage settings.

Vegas are the only profitable choice out there in Gpu mining. I mean truly profitable as there are many other cards which can give you a low profit by mining with them but Vegas are doing great and I think are the only cards to make 0.16 mBTC as a minimum per card daily.

You can buy them now or just wait a little bit as the prices of all graphic cards are going down on ebay very fast , with prices dropping every day. You can build a 6 cards miner cheaper now than it used to be in the beginning of this year.

but do you thing its better to buy them use or to pay 380$ for a new one?

new with 3 years warranty is very tempting I got 4 like that.

If you can find 380 dollars for a new one then that is the best you can do. Still it is a great idea to get used Vega cards if that is your only option as they seem to be the most profitable cards at the moment. Either way you can't go wrong with them and if the developers of Monero keep their idea of decentralisation by forking against ASICS like they already did and will continue to do so.

Hi people, what do you think about this, I have an opportunity to buy 6 Vegas, 6 Rx Vega 56 power color red dragons or 4 Rx Vega 56 red dragon and 2 Rx Vega 64 RED DEVIL they cost 399$ for the red dragons rx 56 and 499$ for the red devils 64, I know that Rx 56 its better price/performance but the 64 can have better resale value and its the RED DEVIL that has better cooling and triple bios, so what do you thing? what would be the difference in mining out of the 2 in different algorithms not only cryptonight?

Buy those that will drop the price for 150$ from stated.

what do you mean? i dont understand

Amd RX Vega is best for cryptonight mining, I can't say about ETH but with cryptonight it can easily archive 2000h/s with castxmr miner.
