Modifying the BIOS of an AMD video card with other operating frequencies or improved memory timings, and then flashing it to the GPU was the main choice of crypto miners for a while. Due to the introduction of BIOS signature verification in the AMD video driver some time ago, this also required users to fix the video drivers in order to continue using them with more recent video drivers. Earlier this year, the AMD Memory Tweak Tool was released, which turned into a pretty useful alternative to modding the BIOS. The latest AMD Memory Tweak XL technology makes it easy to change memory timings, memory straps, or PowerPlay on the fly, as well as access ADL Overdrive and MMIO Register Control on newer AMD GDDR5 / HBM-based graphics cards. This means that you can change the settings and apply them directly, as well as check how they will affect performance and stability, the changes are not permanent, and as soon as there is any problem, you can easily return to the default values.
The AMD Memory Tweak XL tool requires that you have the .NET Framework 3.5 installed in order for it to function, if it is not available on your system, it will automatically detect it and offer to download it for you … although trying to install it may cause various problems some mountain installations. In addition, for the tool to work correctly, Windows must be in test mode, it will offer to put you in test mode if you are not currently working, and there is a button to easily return to normal operation. AMD Memory Tweak XL was originally intended for more advanced users, although you should be able to quickly master what needs to be modified and how to improve performance. You can look at what other users have reported as settings that give the best performance on their specific mining GPUs, and try them, and experiment with the capabilities of your AMD GPUs. Even if you already have a modified BIOS video, you can still play with memory straps, for example, to slightly improve performance and check even better settings before applying them with the new BIOS modification.
Make sure to run the program first with parameter –current to see what the current values are. Current values may change based on state of the GPU, in other words, make sure the GPU is under load when running –current. HBM2 Based GPU’s do not need to be under load to apply timing changes. It is often better to apply new timings before starting a benchmark/mining tool.
Hints: Some timings are stability timings, lowering these will lower stability. Such as tRC. Some timings might require a higher value for performance to improve. Such as tREF. Some timings have a min/max value, going outside this range will result into it defaulting back to original value. Such as tCL Some timings are dynamic, they change based on the vbios values and active clocks. Dram timings. …
Still not all possible timings have been exposed. However, it’s not such a big deal to add more of them in the tool. The ones available are more or like the most important ones.
Some users have reported very nice results already, please continue to contribute to these results. Example

After the collapse of Terra, Celsius, and more recently 3AC and Voyager, a pattern is starting to emerge. It turns out that the high yields of cryptocurrencies and algorithmic stackcoins are not actually sustainable in a bear market (to anyone’s surprise), and as a result, cryptocompanies whose value proposition meets the above criteria find themselves in a desperate position, not a group, but echoing their “Money for Nothing” hit. Here’s a list of cryptocurrencies you should probably avoid:
Because the value of Bitcoin is falling, the mining equipment has begun to operate at a loss. Electricity costs are rising and profits are falling. As Bitdeer points out, some equipment, like Antminer, that was produced in 2019 has stopped making a profit. So far, devices such as Antminer S19 and Whatsminer M30S+ and Antminer S19j are profitable.
Michael Saylor: “Bitcoin will never hit zero” . In an interview with Squawk Box on CNBC, prominent Bitcoin proponent Michael Saylor stated that BTC skeptics and opponents have failed. He mentioned a bill to regulate cryptocurrencies in the US, which Senators Kirsten Gillibrand and Cynthia Lummis have already completed work on.
