Black Friday 2015 I got an 8 pack approved bundle. I(I7 5820k and gigabyte gaming 5P) I was never able to get the ram running at the advertised speed (3ghz) and under the installation guide on the forum it would not even post.... BUT I needed a machine and got it dog stable with the ram at 2666 MHz.

However I recently saw a video showing the difference ram speed makes and Google showed a bios update in 2017 added improvements to ram support
So I installed the bios, copied the settings hoping to get the advertised speed and....... It would not post

The next 2 hrs spent setting it up and..,.... It is practically the same damn speed it was before I started!. ,(Ram is actually at 2750mhz now so a tiny bump)

TLDR should have stuck with if it ain't broke don't fix it (but I never should have accepted the ram in 2015,)

(I ignored the microcode fix in 2018 as I read this can gut your pcs performance)
 
Funnily enough, I'm sat here now thinking my Black Friday 5820k system may have died a couple of hours ago!

Running stock speeds with Sapphire Nitro R9 390 and Corsair RM850.

I'd had the odd glitch or two a month or so back, black screen while gaming before pc shutdown, but behaved ok last two weeks.

Then playing Rocket League earlier, sudden shutdown right at end of match.

Wouldn't boot up, no fan movement on gpu.
Swapped out gpu for newish Sapphire RX580 from better Half's pc, would show initial post but then black screen.
BenQ monitor connected to BH's pc with her gpu works, with my gpu nothing (over DP cable).
BH's pc with my gpu connected to LG TV (over hdmi cable) gives no signal, with her gpu fine.
Tried switching between the two RM850 gpu cables to supply to the two gpu power inputs, no change.

Waiting for BH to finish shift later to try old gpu that she hid somewhere (7850 iirc).

Got a horrible feeling that my R9 390 is dead, possibly my RM850 gpu outputs and maybe even my 5820k X99 system. :(
 
I didn't think RAM speed made that much of a difference on the Intel platform. Literally "an" FPS or 2 here or there? The big gains are mostly with Ryzen stuff as the CPU is/was tied to the RAM speed so getting above 3000Mhz was a real game changer.
 
It makes a difference with Intel as well. When the 7700k launched some sites did testing with fast memory and it was found that some games gain up to 20% performance with 3000mhz+ memory over the old standard 2400mhz.
 
High spec RAM is a bit misleading really. The RAM is guaranteed to run at those amazing specs, alas your PC is not. Just because you bought the RAM does not mean you can actually use it. Personally I have never thought that last few % of performance is worth pursuing, but overclocking is a legit hobby these days and if you are in to that then sure why not?
 
Granted it can take a bit of fiddling with Ryzen but on Intel it's pretty straightforward. I bought 3866mhz memory selected the XMP profile in the bios and it runs at 3866mhz with no messing around needed.
