Upgrading from 5200-6400mhz with a 14700k?

I’ve currently got 2x32gb 5200 ram paired with a 14700k. I’ve read that 6400 will run fine with the cpu even though intel says that the max supported speed is 5600.

Just wondering if anyone’s got any experience of going with a quicker speed that 5600 with a 14700k, and if it worked ok?

Will it be worth it for the amount of extra fps gained?

Unless you are doing something like competitive gaming with a high-end card at a low resolution, or you absolutely hate losing a few FPS in the lows: no.

It is overclocking the memory controller, so there's no 100% guarantee, especially with dual rank 32GB modules.
 
there is an argument for switching ram here, Depending on the games the OP should see a 5% to 10% gain in average and 1% lows.
if the 5200 kit is budget with loose timings.

if you have the money to throw about, then id go it al long as your getting a good kit.

Yes, agreed.

There would be a performance improvement but it’s not really worth the extra money in my eyes and as you said, if OP had money to throw about then sure, go for it.

2 by 32gig is already pretty fast as the higher RAM density over 32gigs improves data throughput and performance. If OP had a 32gig kit of 5200 MT/s and was considering 64gigs at 6000 MT/s, we might say go for the upgrade.

I’d also consider a 48gig kit of Hynix M die at 7200 MT/s as that would be relatively easy to run and have a bigger performance uplift given how Intel CPUs respond to speed improvements.

I just think that both me and Tetras view the extra cost as not really worth it for the relatively small performance improvement.

Certainly not when you could put the money into a new GPU or CPU which would have a greater impact.

if he went to a 14900K the cost would be massive compared to ram and only net him around 10%..
£100 = 10% bad
£400 = 10% good.

we must do different math's
i mean he could go for a 7800x3d but then we are looking at £500ish and depending on the resolution he could be looking at under 10% gains.

its funny how people view different things, you said ram is not worth it but a CPU at 4 or 5 times the cost would be for potentially the same gains.

It is unlikely that the OP is CPU-bottlenecked to the extent that it would offer big FPS gains, so from a general playability perspective I just see it as a waste to switch kits.

A new GPU might offer something new in those playability terms, despite the expense, but the RAM won't. Dual rank 5200 I'd consider "good enough" to get most of the CPU's performance.

I'm not even sure how many CPUs can run 6400 with dual ranked sticks.

The exception for me, is if the OP is doing competitive gaming at low settings/res with a high-end card, then the calculations change.
 
Yeah, what Tetras said.


I’m not saying that buying a new CPU for £1000 is comparable to buying a new kit of RAM, I’m saying that the money you’d spend on buying the new kit of RAM and selling the old kit would be better added to the budget for a new GPU down the road as an upgrade.

Buying a 4080 over a 4070 (as an example) with the slightly bigger allocation of funds would be a better use of those funds given that OPs current RAM is still pretty good.
 
Yes it should work 6400 on a 14700k i would imagine

I used 6600 on a 12600KF which is two generations older and a tier below

but the motherboard may also be important, i had a high end mobo and a custom watercooling loop
