Overclocking RAM on G4900 possible?

Finners · 30 Apr 2018 at 17:25

I have 16gb of DDR4 2400mhz 1.2v CL14 I brought a long time ago second hand and I have no idea if it even works and now with RAM speed moving on so much I'm a little worried it would hold me back if I upgraded.

Am I mad to be thinking of grabbing a z370 board and a celeron G4900 and seeing what the RAM can do with 1.35v? is memory Overcloking even available of celerons? Unsurprisingly I cant find too many examples out there of people trying to OC their RAM paired with a celeron.

The price of RAM is a stumbling block for me with upgrading if I already have a set here that will either give me 90% of the performance if i stick with intel or could be overclocked to relieve the bottleneck.

The max memory speed for the Celerons and probably the Pentiums as well is 2400mhz so I doubt if it's even possible. There can be a substantial difference in performance going from 2400mhz memory to 3000mhz and over depending on the game. To be honest I wouldn't upgrade from what you already have. For the huge outlay you won't see that much of a performance gain in games.

is 2400Mhz the max? I see on the i7-8700k intel page it states DDR4-2666 but from looking around can do 3600+ and on the g4900 it's DDr4-2400 so was hoping it might OC too.

From the CFL promo page:

One fundamental difference compared to the Skylake- and Kaby Lake generations is that Coffee Lake is only compatible with faster and more efficient DDR4-RAM. The four-core processors support frequencies up to 2.400 MHz while six-core processors support up to 2.666 MHz. In terms of the socket itself Intel has opted to retain LGA 1151, although it is vitally important that a motherboard with a 300- series chipset is used. This is due to the fact that the processor may otherwise suffer damage due to alterations in the power delivery system.

The K series cpu's and Z series motherboards are totally unlocked as well so that is a big factor. My wife has a Pentium G3420 in a Gigabyte B85M-D3H motherboard and that board is capable of excellent overclocks (had my old 4670k at 4.4Ghz with exactly the same settings as my much more expensive Asus Hero VI) yet her memory (2x 4Gb sticks of Samsung Green) will not go any higher than 1600mhz (the max for the Pentiums on 1150). What I was able to do though was massively tighten the timings which will make up some of the speed difference. This board was the exception though because not many non Z series boards on 1150 will overclock K series cpu's. It seems like they locked the platform down even further after Haswell so there are no non Z series boards that will overclock now.
