I though RAM Upgrade was Useless, I was completely wrong. Like its only a handful of FPS gain when going to a quad channel.

 

 

As well as from 2666mhz to 3200mhz ram speed, just a handful of FPS gain. 

 

 

But When I upgraded to a 4x8GB 3200mhz Adata Gammix D45 (I just wanted all slot to be occupied cuz it looks so cool lol) from my previous HyperX 2x16 2666mhz. It was a HUGE LEAP! 

 

I'm talking about 50+ gain on CS2! 

 

2x16 2666mhz Hyper X 

 

4x8 3200mhz Adata

 

and not only that, My average on Helldivers 2 was like 70-80 FPS But now with the new ram, its at 100-144 FPS. Shits krazy.

 

Am I stupid or something for missing this out or all of these videos on youtube are scam?

There's no "quad-channel" on consumer platforms, you're just using two dimms per channel, while still being dual-channel.

Maybe it was a combination of both higher frequencies, quad rank, you looking into games that are really sensitive to those things (I doubt you'd see such gains in other AAA games)?

 

Also, how's the CAS latency on your new kit compared to your previous one? Maybe the new kit has better timings as well.

If we're talking about Ryzen 5000 here, its a CPU with only two memory controllers, so only dual channel. In your case, you're likely changing 3 variables, the FCLK, MCLK:UCLK, and how many DIMM slots are populated. Also, potentially better tuning on timings on the 3200MT/sec kit compared to a 2666MT/sec kit.

If we're talking about a 5700x3D and 2666MT/sec vs 3200MT/sec RAM, its more than just a RAM speed increase. Ryzen 5000 wants a 1:1:1 FCLK:MCLK:UCLK. Ryzen 5000 by default has these clocks at 1600MHz, aka what most people think of as "3200MHz RAM" (actually 1600MHz with a 3200MT/sec data rate).

 

FCLK is the fabric clock, which handles the bandwidth between the CCDs and the IOD. This would effectively be all data being sent to and from the CPU cores. Its an additional clock that doesn't need to exist on monolith die CPUs like Intel's right now because there's not multiple dies communicating on the same substrate like Ryzen. Its what allowed Ryzen to be so cheap and powerful, its multi-chip design. Helps increase yield rates and reduce cost by taking the less important bits what's formerly known as the North Bridge and separating it from the main die, aka, the IOD.

 

MCLK and UCLK being the memory controllers and memory bus clocks.

 

Now I don't know if Ryzen 5000 would set FCLK to 1333MHz with a 2666MT/sec RAM kit or if it still runs at 1600MHz and just not 1:1:1. I'd suspect it would still prefer 1:1:1 for stability, and going from 1333MHz to 1600MHz on the FCLK is a significant performance jump, probably more than going from 1600MHz to 1800MHz which is what Ryzen 5000 would want with a 3600MT/sec RAM kit.

 

For reference, Ryzen 7000 is when AMD unbound the FCLK to MCLK:UCLK, which runs in AUTO:1:1. This whole 1:1:1 discussion only applies to Ryzen 1000-5000.

On Ryzen going from 2666 to 3200Mhz RAM can give a good boost in CPU performance when the system is not heavily held back by a weak crappy GPU.

Also, going from 2 sticks to 4 sticks of RAM can sometimes also provide a little improvement depending if the original 2 sticks of RAM are single rank modules. But if you had let's say 2 ×16GB dual rank RAM sticks and replaced them with a 4×8 single rank sick kit of the sam speed then the performance should be the same ish, because having 4 RAM sticks makes it a dual rank configuration.
