HOW TO CHECK MEMORY FREQUENCY DRIVERS
Now you're unable to do that even if you will die of installing it, but GPUs are same story, same vRAM stones and wires, almost same CUDA cores but 3-4 performance boost in certain applications, only drivers and minor stuff differs, so +3000$ for drivers ? Good deal.
HOW TO CHECK MEMORY FREQUENCY INSTALL
it was long time ago, one dude made it to install quadro drivers on Geforce card, guess what ? card started to work like Quadro. That reminds me situation around Quadro and Geforce. I'm not saying they try to lie, the things are what they are, that's it. refreshing the data every 15 milliseconds as well as rewriting the data whenever it is read. DDR4 RAM needs to be constantly controlled. Furthermore, DRAM can only hold information for ~15 milliseconds before they run out of charge. The capacitors holding the information can only be read once before they run out of electricity. DRAM in general has the information obliterated on any read. Your DDR4 chips internally tell the CPU how fast they are through XMP profiles (and standard JEDEC timings for fallback).ĭDR4 has a pretty complicated protocol actually.

There are many, many commands and many different timings associated with them. The actual speed of a step is a "memory timing". The "frequency" is simply the speed that the CPU communicates to the DDR4 chips to issue these commands. Step 0 often happens simultaneously with this step. This copies the data from the sense-amplifiers back into the DRAM cells. This reads ~64 bytes out of the ~2048 bytes that were copied to the sense amplifiers from step #1 By reading the RAM, the data is obliterated in the DRAM cells. Sense amplifiers can be read/written without losing information. This copies one "bank" of data into the sense amplifiers (1024 or 2048 bytes in DDR4). Often done simultaneously with other steps Sets all sense amplifiers to a neutral voltage, in preparation of step 1. "CAS Latency" is a closer measurement of speed with regards to what the actual RAM. If you've heard of "CAS Latency", that is the "Column Access Strobe" part of the DDR4 protocol. The actual speed of the RAM is dependent on the operation.
