effects of Skylake DDR4 memory speed on gaming benches

[magellan]

I only wish I could even get 4000Mhz. stable w/my 9700k, much less 4600Mhz.

Some pretty old info there! Not much difference from 'normal'/'sweetspot' speeds (say 3600), to 4000, eh?

I only wish I could even get 4000Mhz. stable w/my 9700k,

Your signature says you're at DDR4-4009 already.................?

Your system is hamstrung by the 9700k (a lack of core/thread count and speed + IPC) paired with that monster 4090 of yours.

Edit: I get they are similar and iterative/based on Skylake, but, the difference between those generations is quite a bit in and of itself. Just feels weird to see Skylake and then 10th-gen CPU used, for me.

I updated my BIOS to enable SAM/resizable BAR and now I can't get to 4000Mhz. anymore.

Shadow of the Tombraider saw a 10% to 13% diff. in min. FPS between 3600Mhz. and 4200Mhz. DDR4 memory speeds.

Maybe Skylake users might be interested in this article? It's pretty comprehensive about how timings/frequency affect benchmarks.

It's a solid article... just stuff that's been out for a while already/known (there's a couple of articles like this out, DDR5 too). A refresher isn't a bad thing.


...maybe we need to get Woomack to work on a DDR5 scaling article. Those exist already too, but... always worth it.

A 9700K can't be held back that much at higher resolutions, right?

Looks like a decent combination of speed and timings (XMP and 3200-3600) gets DDR4 to a happy place on games where you won't miss any performance.

I'll be stuck w/my 9700k for quite a few years because I blew my computer upgrade budget on the RTX 4090. If it were to die for some inexplicable reason though, then I could justify upgrading it.

Wait... How can you not get 4ghz? I've only got a 9600kf and I've got 4.3!

On his RAM.........which, oddly enough, his sig says he reached. His CPU is over 5 GHz (same sig).

I was confused too, lol.

I upgraded the BIOS on my Asrock to enable SAM/resizable BAR and once I did that I couldn't reach 4000Mhz. w/my memory anymore. The new BIOS did, however, enable me to run my memory @ 3984Mhz. w/CAS 14, which I could never do before (shrug).

If I had time I might be able to get to 4000Mhz. w/my memory but I'm sure it would take hours and hours of pure frustration.

Why does the guy who wrote the article call his Intel i9 10900K a skylake? This list of skylake SKU's from Intel doesn't list any 10xxx parts:

How long ago did you flash the BIOS? Update that signature.

Lol, I asked that in my first post in this thread....

Here's something from Wiki that shows the 'sub' arcs for Skylake.... though, again, they all have different names.... and why I was confused and said what I said in my first post here. 10K series is Comet Lake, a sub-arch of Skylake.

I'm surprised anyone even found this website, and I'm not even trying to confirm if the results/conclusions are right.

SO MUCH MYSTERY!
