I bought the kit linked in the original post. Works fine running at 4800 mhz.
I did the swap on bios 307 and still running fine on 308.
I suggest upgrading the bios before doing the swap. Some people had problems with older bios. 🙂
I read it somewhere on reddit, that they are planning to enable 5600 in a future update.
I wanted to try out the 5600 kit to future proof my setup in case we get it. 🙂
There is almost no difference in price (a couple percent in Denmark).
To be fair they always advertised the laptop with 4800 memory and never said anywhere that it will support 5600 officially at least.
According to Kingston.com datasheet, this 64Gb Kingston Fury Impact DDR5 5600 CL40 (2×32Gb) model KF556S40IBK2-64, these RAMs run at latency timing of 40-40-40. I suppose this timing is for 5600 rate. It would be of help if you write what is the timing at 4800 rate????? I assume that this RAM kit works at 4800 on Scar 18. I would expect better timing at 4800 than at 5600. I can buy this RAM kit or 32GB rip jaws which have the timing of 36-36-36. Thanks.
