Title: GPU ASIC Quality Thread Post by: CoM1ner on February 22, 2017, 09:22:36 PM Hello Bitcointalk!
I wanted to start a thread to gather information about ASIC quality for GPU's. As you know, most miners run air cooled systems where ASIC quality plays a role in better overclocking, less leakage and the ability to run lower voltages. A good way to find out your ASIC quality is to use GPU-Z. This tool can be found below: Installer: https://www.techpowerup.com/gpuz/ (https://www.techpowerup.com/gpuz/) Portable Version (No Install): http://portableapps.com/apps/utilities/gpu-z-portable (http://portableapps.com/apps/utilities/gpu-z-portable) After downloading GPU-Z, click the menu button at the top right of the window (Three parallel horizontal bars) then click the "ASIC Quality" tab. The ASIC quality is read as a percentage. If you could post the model of the card and ASIC quality, we can gather information about which cards tend to have higher ASIC qualities. My results are listed below: MSI Gaming RX 480 8GB: 64.1% MSI Gaming RX 480 8GB: 67.0% MSI Armor RX 470 4GB: 63.3% ASUS RX 480 8GB (Reference): 73.1% ASUS RX 480 8GB (Reference): 84.4% Sapphire Nitro R9 380 4GB: 67.0% Title: Re: GPU ASIC Quality Thread Post by: Zorg33 on February 22, 2017, 11:44:07 PM Just to make clear
ASIC quality != OC potential It has an impact on the required Vddc for a certain freq. But it does not correlate much with the OC potential. As far as you want to run your GPU underclocked & undervolted higher Asic quality is better regarding power consumption.

Most of us are mining ETH and we only OC the memory not the core clock. And there is no such thing as Memory Asic quality. Title: Re: GPU ASIC Quality Thread Post by: ps_jb on February 23, 2017, 07:21:30 AM Rig 1: 6x RX 480 8Gb Nitro+

I am actually switching around to different algos depending on profitability and testing purposes. My friends also mine multiple other algos, mostly Monero. I understand that you may mine Ethereum specifically, but there are others who mine different algos. This was more of an attempt to gather information for future use. Ethereum is supposed to go Proof-Of-Stake in the future, resulting in many miners looking to mine other coins from Ethereum. |
