STEP BY STEP OVERCLOCK GUIDE FOR GETTING STABLE 430H/S WITH GIGABYTE RX560 4GB ON MONERO (XMR) CRYPTONIGHT V7 IN WINDOWS 10Hi, I have made this guide to help out people mining with Gigabyte RX560 4GB cards.
I found that the info for overclocking online is a little fragmented and hard to find all the settings you need in one place.
This guide is for Windows 10 - I couldn't seem to get any changes using Windows 7, decided to try Windows 10 and that seemed to do the trick.I haven't tested speeds on Ethereum (ETH) but I have a stable 430h/s on Monero using XMR-STAK. Power draw on the card is approx 35W and temps are holding around 55C and fan speed is 45% - so nice and quiet, and a great improvement on the 280-300h/s you get out of the stock card. I am currently running 2 cards and this has worked on both cards. Others have claimed to get higher than this though this would most likely require alot of tinkering around that could brick your cards - and they are tightlipped about how they have done it.
First of all there are a few things you will need to download before you begin (trust me, it is easier to download them all first) - just google them - they are easy to find and download:
- ATIWINFLASH
-ATI Pixel Clock Patcher
-DDU display driver removal tool
-SRBPolaris V3.4
-GPU-Z
-MSI Afterburner (or your preferred overclocking tool)
-AMD Video Drivers (either the Beta Blockchain driver or the latest Adrenaline drivers)
-XMR-STAK
I started with a fresh installation of Windows 10 - however this probably isnt necessary if you already have it installed - just make sure to follow all the steps and in the correct order or you may run into some problems.STEP 1. FLASH A NEW CUSTOM BIOS TO THE CARDStart by running ATIWINFLASH, once open it should detect your card. In the bottom middle of the window is a button labelled "SAVE". Press this and save the original BIOS - I called mine OriginalRX560.rom. Once the bios has been saved, run SRBPolaris. In the top right of the screen, you should see a button labelled "OPEN BIOS". Click this button and load up your bios that you just saved. Once loaded, click the tab labelled "Mem Timings" and on the right hand side you will see a button labelled "PIMP MY STRAPS". Press this button and it will change your straps according to your memory type for better performance. Once this has been done you can click the button at the top right labelled "SAVE BIOS". Call it something like ModdedRX560.rom - you should now have your original as well as your modded bios. Now go back to ATIWINFLASH, and click the button at the bottom left labelled "LOAD IMAGE" and select the modded bios file you just created and then click "PROGRAM" and let the program do its thing - it will tell you to reboot but don't reboot just yet.
STEP 2. CLEAN OUT DRIVERS, REINSTALL DRIVERS AND PATCH PIXEL CLOCKNow before you reboot, run the DDU tool to remove your current display drivers. When open in the top left of the screen, click the button labelled "CLEAN AND RESTART". This will remove your current drivers and then reboot your system. Once back in Windows you can go ahead and install the AMD Video Drivers again (You can try the Beta Blockchain driver but if it keeps crashing your system then the latest Adrenaline drivers will do fine), however when complete, do not restart straight away. You now need to run the Pixel Clock Patcher to patch your new bios file or you will receive an error code 43 when the system restarts. Running the patcher should bring up a small window with a series of items and "FOUND" next to each item. Click "YES" and wait a few moments and once it is complete, you can restart your system again.
**Just remember to run the Pixel Clock Patcher after any reinstallation or upgrade of your graphics driver before rebooting the system due to the custom bios on the card**
STEP 3. SET UP YOUR CARD FOR MINING.Once back in windows, your card should be installed and working properly. You now need to open up the AMD Radeon Settings, go to the "Gaming" tab, go to "Global Settings" and change the workload option from "Graphics" to "Compute" (not needed if using beta driver). The settings will restart for this change to take effect. The next step is to set your core and memory speeds. I use MSI Afterburner but feel free to use another tool, just remember to use these settings. I adjusted the Core Clock to 1130 and the Memory Clock to 1950 and set the fan speed at 45%. Your card should now be set for mining optimally.
STEP 4. SET XMR-STAK CONFIGURATIONSo the last step now is to set up the AMD configuration file in XMR-STAK. Go to the folder where you installed this and there open the file named AMD.txt and make sure the config looks like this:
"gpu_threads_conf" : [
// gpu: Baffin memory:3196
// compute units: 14
{ "index" : 0, "intensity" : 448, "worksize" : 8, "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2, "comp_mode" : true },
{ "index" : 0, "intensity" : 448, "worksize" : 8, "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2, "comp_mode" : true },
],
If running multiple cards on one board, alter the file accordingly, so for 2 boards it would look like this:
"gpu_threads_conf" : [
// gpu: Baffin memory:3196
// compute units: 14
{ "index" : 0, "intensity" : 448, "worksize" : 8, "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2, "comp_mode" : true },
{ "index" : 0, "intensity" : 448, "worksize" : 8, "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2, "comp_mode" : true },
{ "index" : 1, "intensity" : 448, "worksize" : 8, "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2, "comp_mode" : true },
{ "index" : 1, "intensity" : 448, "worksize" : 8, "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2, "comp_mode" : true },
],
Now you can save this file, and run XMR-STAK.
Your cards should now be hashing at a stable 430h/s each with a stable temperature of 55C and a power draw of approx 35W (You can use the GPU-Z tool to monitor the power draw and temps).
