For each memory clock available for a GPU you'll find a Timing Strap value, which can be modified in three ways: Pay attention to a section in a lower-right. It allows you to change clock speeds, voltages, TDP, temp limits and timings directly in BIOS.Ĭlick "OPEN BIOS" at the top left corner and select a file you have just dumped using GPU-Z. You'll be able to safely revert any changes using the original BIOS. "Save to file." and choose the folder to backup your BIOS to.Ĭopy the file to a secure place, i.e., Google Drive.Click on the arrow under AMD Radeon logo.Find out what memory chips are installed on your board. AMD RX RADEON 580 4GB THREAD STUCK IN DEVICE DRIVER DRIVERA driver will be unable to detect your GPU after BIOS reflash if you skip this step. Launch atikmdag-patcher.exe to disable BIOS checksum check. AMD RX RADEON 580 4GB THREAD STUCK IN DEVICE DRIVER PCReboot your PC after the installation is complete. AMD RX RADEON 580 4GB THREAD STUCK IN DEVICE DRIVER INSTALLInstall the latest AMD GPU driver and enable Compute Mode. We've got 27Mh/s after applying a memory overclock. Performance is measured for Ethereum mining. In our example, we are using MSI RX480 GamingX with Samsung memory chips. AMD RX RADEON 580 4GB THREAD STUCK IN DEVICE DRIVER SERIESThe process for AMD 400 and 500 series is the same. Figure out your memory's manufacturer and backup stock BIOS, both using GPU-Z.Apply atikmdag-patcher to bypass driver's BIOS validation.Install the latest AMD driver which is optimal for mining.But, if you'll carefully follow these steps, everything will work out. Test your GPU thoroughly after flashing or stick to a soft memory overclock if in doubt. Sometimes the driver can even stop responding, resulting in an immediate game crash or even a BSOD.īe conscious about the risks before considering modifying the timings. Visual artifacts in gamesįlashed GPUs are prone to display random green lines or blinking noisy squares on a screen while playing games. Such shares do not get rewarded by a pool therefore your profitability will decrease. Overstressed GPU might think that 2+2=5, thus generating an invalid share. It's not only about miner crashing or PC hanging. The Ferrari example above is still applicable - there is no point of going lightning fast for a split second just to get stuck turning into a snail a moment later. Mining relies on long-term stability and reliability, not immediate blast power. Frankly, that applies to any overclocking and the mining process itself, so. Pushing your GPU's capabilities beyond those may bring unpredictable consequences to card's work state and lifetime. Manufacturers test their product using stock parameters and make assumptions about life-span, assuming that the product is working in the same conditions as a test bench. Reverse all the modifications before handing your GPU to a vendor. AMD RX RADEON 580 4GB THREAD STUCK IN DEVICE DRIVER FREENo service center will provide you with free maintenance if they find out that any BIOS changes were applied. Indeed, there are some risks associated with BIOS modifications, but with careful planning and following our instructions, those risks are easily avoidable. It is a simple method which doesn't require any specialized hardware. AMD 400/500 series, on the other hand, allows you to use Polaris BIOS Editor app to apply custom modifications. But most of the cards would require complicated microcode edits. Which cards can be reflashed using this method? There are three ways to boost DRAM chips: So, what is the point of that speed limited by obstacles? But, you are always stuck at traffic lights of timing/latency at every corner. Your car can reach 250 Km/h of frequency. These latencies are crucial for stable memory performance, but they are not optimized with mining in mind. Timings, which define the latency between read and write operations. The higher the value, the faster the data is transferred. As a whole, it has two major parameters:įrequency, which impacts the memory's speed. RAM and VRAM are types of Dynamic Random-Access Memory. Lowering memory timings may help to push a card even further and provide up to 31 Mh/s - a 7-9Mh/s increase! The only way to do so with an AMD GPU is to flash BIOS. We covered this approach here, yet, you still can squeeze some more by reflashing your GPU's BIOS with lower memory timings. You can push up to 29-31 Mh/s by tuning the memory clock. Stock AMD RX 470/480/570/580/590 are capable of 22-24 MHs/s mining Ethereum using DaggerHashimoto. The article down below is left as it was, just for the reference. ⚠ BIOS flashing best suits 4GB cards ⚠Ĭlaymore miner arguments now let you achieve the same results in a non-invasive and easily reversible way with 8GB cards.īy tweaking the -strap, -sintensity, and -rxboost options, you can adjust the timings of your GPUs and increase hashrate by 10-20% depending on a GPU model and memory chips installed. ![]()
