Can ram bottleneck a high end system?

I have absolutely terrible ram, super slow speeds and it doesn't even have a brand on it. It's 2x4 but it's literal garbo, could that bottleneck my 4790k and 1080?
 
Solution
It's 1333Mhz. It's an off brand. 1866MHz RAM would be better. You may see an FPS gain. With that being said, it can slow down the show.

I went with 2 x 4GB 1866MHz CL10 Kingston HyperX Fury.

If you upgrade a 16GB 1866MHz kit(2x8GB) is recommended.

Sell the slow sticks or keep in case of emergency.

So do you think this could be a reason why some of my games are running poorly?
 


Have you used MSI Afterburner's OSD and watched your RAM usage? I think it could be the reason behind MAYBE 10 FPS.

I turned of my paging file. I have 8GB and my games are on my SSD. A day or so later I am playing a game. Not really going to look for the question. I haven't came close to 6GB RAM usage. But I had some bad gaming experiences. I came here and asked about some odd performance issue. Long story short, Iturning off the paging file hurt the game.

Could it be the issue? Yes. Can other factors also be causing an issue? yes.

The 4790K most likely isn't the issue. It can be happily married to the 1080. So too can my 4690K. Could it be getting too warm and thermal throttling is the issue? Yes.

GPU thermal throttling? Yep.

I most certainly see a lot of value in a new 16GB RAM kit especially when Ultra settings are wanted.

A problem? Definitely.

The problem? IDK.

Thermals are all good, cpu is watercooled and the gpu doesn't get to the point where it would need to throttle, I have to assume it's the ram. I don't believe a 4790k would bottleneck a 1080
 
Water cooling can introduce issues for your motherboard, namely the VRMs. Without proper cooling they can get to warm and not deliver proper power to the CPU. Make sure you look at frequencies and load for the CPU and GPU.

1333 will hold you back some from 1600/1866. It used to be 1600 was the sweet spot and now we are moving onto 1866 or 2133 being the sweet spot for DDR3 ram. If you have true garbage 1333 with high CL timing ram you will do better getting newer better stuff. Is it enough to fix all your problems? Can't say.
 
RAM is usually responsible for 1 - 5% performance. Intel CPUs do exceptionally well in this regard, and tend to cope very well with lesser memory performance. The only architectures I've heard of gaining more than this are AMD APUs and Ryzen. Ryzen has the Infinity Fabric in the CPU tied to the RAM frequency in some way, and APUs need the higher speeds for better GPU performance. While you may gain a few frames per second by spending on better RAM, your performance issues probably lie elsewhere.
 


Good point. More thermal stuff.

Heat's a mean pickle!!!!

People decide to go very cheap with their motherboard. 2 RAM dimm slots. A CPU socket. A PCIe slot or 2. 4 SAta ports. Just the facts(basics) ma'am. Then they get heat issues. Many inexpensive MBs lack passive heatsinks for VRMs and other parts of the motherboard. My CPU is fine. Why is my motherboard so bleeping warm?

I'd play one of your most demanding games with HwMonitor or HwInfo running in the background. Someone may be able to glean an answer or 2 out of the results(posted SCREENSHOT) because they do record the min, current and max temps, amongst other info during the entire session.

You can have MSI Afterburner's OSD on inside the game so you can monitor resources in real time.

Most likely going to buy some new ram soon
