I had a well working 元+, then by mistake flashed it with D3 firmware (instead of different ASIC device. Let me know if you need any help.Ībsolutely the same stuff I'm having now with my 元+ too. Hmmmz I'm afraid you need to flash them by hand on the board itself. Nov 21 10:01:48 (none) local0.notice cgminer: Chain 3 ASIC 0 !!! Nov 21 10:01:48 (none) local0.notice cgminer: Chain 2 ASIC 0 !!!

It is also the closest to where the central processing occurs, being a part of the CPU itself. The CPU cache stands at the top of this hierarchy, being the fastest. Lastly, the CPU has even faster memory units within itself, known as the CPU memory cache.Ĭomputer memory has a hierarchy based on its operational speed. Your computer and its programs use RAM to store frequently accessed data, helping keep actions on your computer nice and fast. This is much faster than the primary storage but is only a short-term storage medium. Next up, we have "random access memory," commonly known as RAM. Primary storage, like a hard disk or SSD, stores the bulk of the data-the operating system and programs. Now, your computer has multiple types of memory inside it. The system memory at the time (RAM) couldn't cope with or match the increasing CPU speeds, so a new type of ultra-fast memory was born: CPU cache memory. However, during the 1980s, processor speeds began to increase-rapidly. In the early days of computing, processor speed and memory speed were low. Put simply, a CPU memory cache is just a really fast type of memory. So, exactly how important is CPU cache, and how does it work? What Is CPU Cache Memory?
