The very useful AMD Memory Tweak Tool that was initially only available for Linux is now also available as a beta for Windows users as well. With the help of the free and open source software from Evilop you can read and modify memory timings “on the fly” for compatible AMD GPUs that do come with GDDR5 or HBM2 memory (HBM was also supported initially, but is temporary disabled as it apparently need some fixing). Before starting to do anything with the tool you should check the Readme and run AMD Memory Tweak with the option --current in order to see what GPUs it detects and what memory settings are currently active. It might also help to see what other users have found out as good working configurations for their hardware and have reported on Bitcointalk based on their experiments with the memory tool.

There is a new interesting tool released by Eliovp for modifying the video memory timings of AMD GPUs on the fly, so no need to modify and reflash the GPU BIOS anymore to do so. The not so good news for some users is that the tool is currently available for Linux only, but still you can test under Linux and make permanent changes via BIOS if needed after that for mining under Windows. The AMD Memory Tweak tool supports GDDR5 an HBM/HBM2 memory AMD GPUs and should be able to help increase hashrate in memory intensive algorithms such as Ethash for example. The AMD Memory Tweak tool is similar to the ETHlargementPill for Nvidia GDDR5X-based GPUs as an idea and functionality. The software is available as open source and is completely free to use, however you are welcome to send the author a tip if you find it useful.

If you are using reference design AMD Radeon RX 480 GPUs for mining Ethereum only or Dual Mining Ehtereum and DCR or SIA and you still not have tried any of the custom video BIOS roms available from Heliox / Eliovp you should give them a try. With the right clocks and timings you might be able to achieve over 31 MHS hashrate apparently from an RX 480, or a bit less with much lower power consumption if that is what you are looking for – to optimize power usage. As usual with BIOS modifications always make sure you have a backup of the original ROM file in a safe place should something goes wrong, so that you can get everything back to normal operating mode again.

The availability of the PolarisBiosEditor tool now also allows users to experiment with different settings and memory timings in order to achieve even better results for their mining configuration, such as optimum hashrate for a dual mining system and not only for mining Ethereum alone. So you might want to check the tool as well and use it to optimize your GPU even not for mining Ethereum for instance as it allows you to play with a lot of settings in the BIOS.
