Is 2133 MHz memory good enough?

[Hoppled]

I recently upgraded from 8 GB of DDR4 to 16. Only thing is, my mobo reads it at a slightly lower frequency - 1064.5 MHz DDR.

I can enable XMP 2.0 in bios, which I did, but I didn't notice much of a difference. Regardless, for now I decided to set it back to the default because I want to update my bios.

Is 2133 MHz DDR4 too slow? I don't play the most demanding games, but I was excited to finally have 16GB DDR4 instead of the measly 8GB I'm so used to.

Thanks.

ddr speed = mhz x 2

ddr 2133 can be good if its cl11 or lower, but most ddr4 2133 is cl15 or higher

also depends on the cpu
ryzen and intel 8th gen and later like ram over ddr 3000 (1500mhz)

6-7th gen intel cant use much fater than 2666 (1333mhz)

and more slow ram is better than not enough when you need it

1064.5 x 2 = 2133MHz, thus the name Double Data Rate.

I don't think DDR4 has a slower model unless you manually downclock it further. From a gaming sense yes 2133MHz is slow and can be an obvious source for bottleneck. Depends on what games you're really into, you may wanna at least consider 3000MHz sticks if possible.

The sticks are 3200 MHz, it's just the mobo down clocking it. I can enable xmp to get the 3200, but I heard XMP 2.0 isnt that stable as opposed to 1.0. I need go update bios to hopefully get the 1.0 option.

Its corsair vengeance LPX dual channel ram. And if it matters- my CPU is Ryzen 5 3600, GPU is rx 580

Interested to know where you've heard that from...

If your 8 GB was being read as faster than the 2,133 MHz you're seeing with the new set, you likely had X.M.P. enabled before on the old set anway.

If the X.M.P. profile works, there's little reason not to use it. Yes, 2,133 MHz is rather slow IMO (it is about more than frequency as timings are the other half, but presuming they cancel each other out at worst, I'd always opt for the higher frequency). If buying these days, little reason not to go with at least 3,200 MHz. It's usually not much more expensive and has documented performance benefits.

xmp sets the ram multi, timings and voltage
if the fsb/bclk is above 100 the freq will be higher its rated since its fsb/bclk overclocked

Build-a-PC reddit, but he said it was just something he heard and that I should update bios to the current version to see if XMP 1.0 shows up.

Thing is, I gotta use a usb flash drive to safely update my bios... I'm not too experienced with that.

ddr4 uses spd 2.0 or later, no way to use spd 1.x (ddr3 specific) with it

Seriously though, I wouldn't take whatever that random guy has to say at face value. If XMP 2.0 has this big a fundamental issue you bet it'll be covered by dozens of major tech sites years ago.

BIOS isn't something that should be updated 'regularly' unless you've found the issue you're having to be specifically related to it. I think AMD call it DOCP instead, select the 3200MHz profile and see if there's a problem first.

if you are mixing ram you wont be able to use faster ones xmp/spd profile

Okay, thank you. I was able to get the speed up to 3200, but what's odd is that it was an XMP 2.0 profile (only profile besides auto) - it works fine so far, but why would XMP show up if I'm on an amd cpu/gpu. The mobo is Asrock b450 not sure if that matters though.

Why shouldn't it? It's an intel tech but it can be used on AMD CPUs. I've just read that in some cases it's more optimal to manually OC your memory on AMD rather than letting XMP do it with everything on auto (especially for timings).

its the same thing spd, intel calls it xmp, amd calls it docp

[A&A]

depends on the processor that is my answer

ram is rarely the limiting factor for fps
often limited by gpu and cpu first
