What to do about my rubbish 2666Mhz DDR4

Zeebedy · 26 May 2019 at 23:21

FWIW - I was getting around 180-230 fps on CS GO. I couldnt work out why but when I enabled XMP on the BIOS for the 3200mhz, i am getting mostly maxed out 299fps and minimums of around 245-250 ish.

I've ordered a 16Gb kit of the Kingston 3333Mhz. The only way to stop myself going over the pros and cons is to just buy the damn stuff and forget about it

Bought it, stuck it in..bugger all difference

Looks nicer in my non windowed case though.

Strangely, still glad it's there!

i have to call bull poo on this. there is no way XMP 2400mhz to 3200mhz gave you 100fps.

it was at 2133. I might have changed other settings but..im 99% sure i didnt.

TBF 2133 is the poo end of the stick, you would see a big jump in performance but 100 fps is insane

but is it possible? I mean CS GO isnt the most demanding game in the world to run?

I must have changed somethign else then..

it is possible if the ram was holding back the cpu, it could have unlocked the full potential of the CPU vus feeding the GPU better

See my post no 7, it's due to caching on the i7, plus combined with slower timings on the faster memory.

As mentioned some software does benefit from faster memory, but majority of time faster memory is not worth it.

Actually faster RAM and tighter timings but your point still stands. I'm actually getting slightly better scores in older benchmarks and Kontakt does seem to switch between samples faster but that could be Placebo effect

There will be a difference, it depends mainly on the software. For example WinRar when it does a solid compression is looking at the entire memory area. This results in low cache hits so faster memory will make a good speed improvement. Another area is VM machines where the VM's are context switching, again low cache hits as high bandwidth involved with multiple running VM's from the same physical machine. I expect similar is happening with Kontakt.

However for most Windows processes and applications there is a large amount of cache hits, so as you are noticing the faster RAM is not making your computer faster in any general area.

When people consider CPU's they choose on core count, but the importance of larger on-board cache especially on i7 and i9 CPU's is often overlooked.

I think you understand where i'm coming from anyway

Yep

I'm also just happy that the upgrade went smoothly. I never expected a huge boost just happier knowing my RAM isn't a "weakest link".
