My GPU is a 3080 ventus . 6000 can’t does work ..?? I buy 6400 no 5600.. pffff . I carried out tests which do not present any worries why I would have some in games?? if a problem were present would it not be noticed on tm5? I need to lower to 5600 ????
Ok, 3080 Ventus should have a TDP of 320W which corresponds into an equal amount of heat output, that's a lot.
The cooling fins are laid out in the "traditional" way, meaning towards the short sides of the PCB, so the hot air is pushed onto the motherboard and towards the side of the case:
If you think that this considerable heat towards the RAM area contributes to an instability, then you could try to undervolt your 3080 a bit:
About the RAM speed that's on the packaging, you can buy RAM with whatever advertised speed that you want, but that only means that the RAM itself is capable of it.
However, the following factors all affect if the RAM can run at a certain speed:
- Your mainboard (PCB layer count, PCB trace optimization, RAM slot layout, component selection, RAM VRM etc.)
- The mainboard's BIOS optimizations
- Your CPU's integrated memory controller (IMC), quality depends on the individual CPU (silicon lottery, not only for CPU core quality, also for Uncore/IMC quality)
- And finally, the properties of the RAM modules.
As you see, the RAM is just one piece of the puzzle in the memory system.
I already mentioned that
here before: XMP is never guaranteed, it's just a goal that can be achieved under ideal circumstances. If someone from the future brought back a kit of DDR5-8000, will it run at DDR5-8000 in any current hardware? Of course not. But the RAM itself is not the limitation. The board, BIOS and IMC are not capable of it at the moment, such speeds require future platforms.
DDR5-6400 is at the limit of what is possible on today's only DDR5 platform (12th gen / 600-series). We will see how future DDR5 platforms will do (see
timeline). But right now, it can be difficult.
