Default Memory Upgrade for 7700k System

Hi guys
I currently have some G.Skill 2x8GB ram @ 2666MHz using XMP. I notice a real bottle neck when playing PUBG in cities as my FPS tanks but my CPU is at 5GHz under a Noctua D14 and I have a 1080, both of these aren't running at max load

I want to upgrade my ram to a higher MHz but I have a few requirements:
- Needs to be 2x8GB sticks
- Compatible with my cooler (max 44mm IIRC)
- NO LIGHTS (or the ability to disable them?)
- Must work with XMP settings, I don't want to muck around with timings - just et and forget in the BIOS
- At least 3200MHz, the faster the better.

The two I am looking currently looking at are G.Skill Trident Z 3200 & 3400 Models $285 and $345 respectively.

Thank you in advance for your help
(ps buying from NZ)

best value option would be to grab a g.skill 3200c14 kit from newegg and oc it
https://www.newegg.com/global/nz/Pro...CE&PageSize=36
i believe the ripjaws 5 are 42mm and the trident-z are 44mm
my kit reached 3866c16 or 4000c17 1.43v with a 6700k and while 7700k should handle higher speeds better what mb you have will also have a big influence on this

its only the kits with tighter timings with the samsung b-die chips that oc really well

assuming pubg responds similar this should give you some idea of the kinda gains you could expect from higher ram speeds

I hate to side track, but you mentioned PUBG, I have no issues with 4770k at 4.2ghz with 2600mhz and a 1080ti on WIN7. PUBG in general has issues and you need to find out solutions to help it run better.
I set affinity to high, I got a 500gb ssd jus for pagefiles and to run PUBG off, and changing in game settings to maintain FPS.
In early days it ran like a pig at 20fps, now though it's 100fps all day at 1080p.

Thanks mate. I actually just grabbed the 3600 version of that ram so I'm sorted now!


You do have a better GPU than me which might help? Not sure, I did install windows with a rx570 and then changed to this 1080 I now have might that also have something to do with it? (Game is running of a dedicated SSD windows is on a different SSD)

i think 3600c17 ram uses different chips and wont oc\perform as well as the 3200c14 kit can
3600c16 kit on the other hand does use the samsung b-die chips
but if you didn't really want to oc the ram outside of its xmp profile anyway then they would perform much the same at there xmp so it doesn't really matter

Thanks Dasa2, yeah I don't have the time to spend mucking around with overclocking these days, I just want to plug and play, I'm happy to pay the extra $20 for the ability to do that.

Did the increased ram speed fix your framedrops in PUBG?

Surprised you got such a dramatic difference there. Just goes to show that PUBG has some optimisation issues they really need to iron out.
