1  Alternate cryptocurrencies / Mining (Altcoins) / What coins to mine with 2GB GPUs? on: December 03, 2020, 04:30:42 PM
Feel free to post any coins/algos you know that can be profitably mined with 2GB GPUs! Thanks

on hold

NOT FOR SALE ANYMORE. If you're very interested and want to pay above market price, shoot me a PM

The hardware is in excellent condition, as it was run in a cool environment with nearly no dust. Nevertheless, all GPUs, motherboards and PSUs were cleaned with canned air.
Open to negotiate if you're interested in higher quantities or want to buy everything.
Generally I'm only interested in selling the parts in bulk and for GPUs I'm looking at a MOQ of 50.
4  Economy / Computer hardware / [WTS] Brand-new RX 550 GPUs (different models) on: April 16, 2018, 04:19:27 PM
Hi everyone,

I bought too many GPUs for my cryptonight farm (so far hit 490-505h/s on every single one, no guarantees) and would like to sell the surplus ones.

I have:
52x ASUS RX 550 2GB $132 (without VAT)
54x Sapphire RX 550 4GB $140 (without VAT)

Potentially could also sell 370x Gigabyte RX 550 2GB for $135 (without VAT).

Both can be picked up in Germany or Switzerland, or sent anywhere in the world (on your cost).

We can meet up in southern Germany or in Switzerland.

Pm me here or add me on discord: MoneroCrusher#4923


Kind Regards
MoneroCrusher
5  Alternate cryptocurrencies / Mining (Altcoins) / Anyone got Vega to mine XMR (/w 17.10.2/17.10.3 drivers) above 1800 H/s? on: October 30, 2017, 06:59:19 PM
Wondering because having 12 GPUs in a rig would be saving a lot of costs.
Mine stays at around 1200-1300 H/s with 17.10.2 and Windows build 1709, maybe somebody got it figured out?

Kind Regards

6  Alternate cryptocurrencies / Mining (Altcoins) / Vega 56 & 64 on Linux (did anyone get it to work?) on: October 01, 2017, 10:27:38 PM
I'm wondering if anyone got Vega 56 and Vega 64 GPUs working on Linux for mining XMR (or any other coin) on Ubuntu, Debian or any other Linux distro.
I can't get XMR-STAK-AMD to work on Ubuntu 16.04 LTS with either 64 CU or 56 CU. clinfo shows both GPUs but when starting the miner
I get the following error:

NOTE: your OpenCL library declares to support OpenCL 1.2,
but it seems to support up to OpenCL 2.1 too.

I hope somebody can help me. Running a windows rig is a pain in the ass with the beta blockchain driver with more than 4 Vegas...
