8400mhz cl 40 vs 7200mhz cl34

[Ceml]

It will be used with intel i9 14900ks and Asus Apex Encore Z790(or formula),

 

Which kit wil give me better fps, 

Or does latency beat mhz

 

Rams: corsair titanium or team group) 7200mhz cl34 

 

Gskill 8400mhz cl40 48gb

Or

 

corsair 6000mhz cl30 96gb

in this case I wouldn't go for a higher latency kit even if the speed was higher

won't really affect FPS. get the 6000 CL30 if you need the extra capacity. But for gaming you won't need it so I'd get this

Silicon Power XPOWER Zenith RGB Gaming 64 GB (2 x 32 GB) DDR5-6000 CL30 Memory (SP064GXLWU60AFDF) - PCPartPicker

is it already on sale?

Intel struggles to go to 6400mhz xmp or manual tuning forget about these speeds. You are lucky to reach 7000mhz really and it doesn't do shit for performance as they can't really use these speeds effectively

 

So ya know just get some 6000 cl30 ram or so. Also euhh a 7800x3d will give you MORE FPS. It's a better gaming cpu than the 14900ks.

 

Whats the reason you are spending a mid range pc's worth of money on a board? Like it isn't even better than a 250$ already overpriced z790 all it has is a fancy look which does nothing for performance and only adds more rgb software garbage needed which REDUCES performance.

You need both. A good balance of both.

8400 would be much faster but generally isn't very easy to get stable depending on your IMC and mobo. You also need the z790 apex encore as its a 2 slot or 1dpc motherboard, the z790 formula is 4 slot and can't reach the same speeds.

If you get 8400 you basically have to tune it's voltages and timings for stability, stock XMP is not likely to work.

Lower the timings/latency, the better.

However, you want a balance of high frequency and low latency.

 

You are not going to be able to run such high frequency like DDR5-8400 without manually tweaking and overclocking the memory.

You might not even GET 8400 MHz to work and have to settle with something between 6000 ~ 7200 MHz.

 

You are not going to see significant FPS gains from ~6000 MHz vs 8400 MHz.

It doesn't scale linearly.

 

What's up with 48GB vs 96GB?

Get the capacity that you need.

 

If you can find something like DDR5-6400 ~ DDR5-7200 with CL30 / CL32, that would be the "sweet spot."

none , your maximum fps is determined by the monitor not the ram

If you have to ask, 6000 CL30 or 6400 CL32. Both of those should just work with no effort on any board, as the 7200 speed bin is iffy depending on your memory controller (it's about a 90% chance of working at XMP, pretty likely but not reliable) and 8400 just doesn't work on most CPUs. Besides, there's diminishing returns past 6400. 

 

Yes, higher memory speed is usually better, and since CAS latency is measured in clock cycles, 7200 CL34 and 8400 CL40 have roughly the same effective latency as each other. It's more a matter of reliability than it is for raw performance.
