RAM bottlenecking my rig?

[MrTralala]

So I just recently built my rig containing an i7-8700k (OC to 4.7 Ghz) and a Zotac GTX 1080. The CPU cooler I am using is the Cryorig H5 Universal and temperature all seems fine.

 

However, I am a little disappointed that I can't run CS:GO consistently at 300+ fps at high settings at 1080p. I have 2 1080p 144hz monitors, one being 24 inches the other 24.5 inches. I run it on my 24 inch monitor (don't ask me why).

 

I have reinstalled Windows 10, tried running 1 monitor only, turned on High Performance mode in Control Panel, ran userbenchmark (http://www.userbenchmark.com/UserRun/10711434) which indicates it's fine, and had a cinebench score of 1452 cb. In the background I have Avast Antivirus, Backup and Sync, and Dropbox running, which I suspect might also be the culpurit(s) of hindering performance. For Google Chrome I have AdBlock and uBlock Origin and all the junk extensions that came with Backup and Sync.

 

If you see the userbenchmark though, my worst bench is my RAM which is a single DDR4 1x16 GB stick from Hynix running at 2133 Mhz. Before anyone thinks that I actually bought this RAM, no, I did not. It came from a prebuilt which I took and used to save cost. Now however, I am starting to think it might actually be the one resulting in the lower fps.

 

Not only CS:GO, but Fortnite PVE (not BR) seems to run very bad (though it could be the game) as I get around 60-120fps on on all high settings and only epic view distance. I could name a few other games that I tested, but you catch my drift.

 

Could my RAM be preventing me from let's say, getting that extra 50+ fps? According to this reddit post, one of them reported that he/she "got like 50fps by getting another 8gb of 2133hz".

if you're hitting 144fps then thats as fast as you can view it anyway , seems like a humble brag thread to me

That's completely besides the point. I am just using CS:GO as the benchmark. If I could, I would have used Fortnite PVE but not many people do benchmarks for it which is the problem.

 

And besides, I am not hitting 300+ fps consistently, there are times where I just dip below 144fps as well.

Possible, single channel is quite bad when games nowadays are begging for memory performance to hit super high frame rates.

lol sth bad will start

Hm...is there a way to test this for sure? I am currently on a tight budget and don't wanna end up in a scenario where I buy the RAM and realise it wasn't the problem.

try up the memory frequency to 2400. If it crashes, push the memory voltage to 1.35V. any performance gain (it will be tiny, since the overclock is minor) this way shows memory bottleneck.

i'd call it a brag thread, but then i see the single channel 2133 lol.

 

running the ram at 2133 and single channel is probably a 25% bottleneck compared to 3200 duo channel on the cpu.

Ok so I did it and yup, performance was slightly better. To prove that it wasn't placebo effect, I ran CS:GO and went to the parts where my fps would just dip below 144 fps but it never did, though it came very close to. I was sitting around 200-350 fps, though anything beyond 300 fps was at a few places only. In case anyone is wondering, I was playing on Mirage and Cache both in private lobby and deathmatch.

 

I also ran Fortnite PVE which was a mixed bag because this game wasn't always the most consistent game in terms of fps and is coincidentally undergoing performance updates atm. This makes it hard to tell so I can't say much.

 

I guess the conclusion is that my ram is likely the bottleneck. Time to throw more money.

 

Thanks for the help btw :).

Since I'm gonna have to buy new RAM, I was thinking about the Kingston HyperX Fury 16GB (2x8GB) DDR4 2666MHz. Anyone has any thoughts on this?

 

EDIT: I just realised that the Corsair Vengeance LPX 16GB (2x8GB) DDR4 2666MHz also cost the same as the HyperX's one. Is there any difference?

Hmmmmm....it's hard to say because I'm buying from a local online store called Lazada and their prices and variety differ from Amazon's. But I guess...180 USD?

also check for 2800, 3000 and 3200 kits. tbh 2666 x2 is about 90% as good as 3200 x2 at stock will be, and if you're willing to overclock further and adjust timings you will likely claim back that advantage yourself.

 

If you dont know or havent tried overclocking memory and adjusting the timings, you can tyr it with your current stick.

Man Trident RAM looks sick as hell but sadly it's very expensive in Singapore. As for Corsair, I only found something similar to it (https://www.lazada.sg/products/corsair-vengeance-led-16gb-2-x-8gb-ddr4-3200mhz-c16-dimm-desktop-memory-kit-red-led-i165824886-s213016004.html?spm=a2o42.searchlist.list.3.352c773074yAve&search=1). Will it suffice?

looks like they are the same as the first kit but with led, if it's actually a decent price for you where you are buying it
