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.

No 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.
