Question is 10gb ddr3 1333mhz good enough?

[ofek cohen]

hi, i have 10gb of ddr3 1333mhz ram,(its 4+2+2+2), and i wanted to ask, is it enough for 1440p gaming?
i recently upgraded my gpu from 1050ti to a 1080 ti and experienced bad performance so i've sent the card back to check if its faulty or not. but until it gets back i want to know if the bad performance could have been caused because of my ram. by bad performance i mean for example:
in far cry new dawn 1440p ultra settings, im getting an average of 62fps and it goes down to 45 sometimes, i have seen benchmarks on youtube with the same gpu getting above 100 fps. but they had a newer cpu at a higher clock speed, and a lot more ram at a higher speed. could it be the ram?
my specs:
cpu: i7 4770k 4.2ghz
gpu: Gigabyte GTX 1080 Ti Aorus Xtreme
motherboard: ASUS MAXIMUS VII RANGER
ram: 10gb DDR3-1333 / PC3-10600 DDR3 SDRAM UDIMM
power supply: corsair hx 1000i model: rps0004 (1000w)
thanks

Running mismatched sticks of ram is definitely not recommended. That could definitely be a big part of your issue.

Check out Gamers Nexus video he did on the i7 2600k revisited from last year. The results from the i7 4790k are in there so it may give you a close idea as to what to expect.

Here's the read me he posted about it on his site:

The higher clock speed and better single thread performance are a few reasons why they're getting better FPS. Low speed RAM (DDR3-1333 is slow) with poor timings can also further hold things back. The game engine for Far Cry 5/New Dawn has been demonstrated to have its performance effected by the CPU's single thread performance. This is why all the Ryzen chips have lower FPS than the Intel chips on that specific game. If you could overclock that CPU a bit it will likely help with your FPS. You RAM should be running in Flex Mode (CPU-Z will say "Channel # Dual" on the Memory tab) which has little to no performance impact until you reach the single channel remainder. Even in that single channel remainder the performance shouldn't be so drastic an effect. See the below link (intel) to see what Flex mode is.

Running mismatched sticks of ram is definitely not recommended. That could definitely be a big part of your issue.

I never said you "can't" run mismatched, I said it was not recommended. There is a reason matched sets of memory are sold in pairs. They're not sold in mismatched pairs. They're not sold with 2x 4 gig sticks and an odd 8 gig stick"

Of course for every "fact" you find on the internet you can always find websites that refute it but the major consensus is you should not run mismatched pairs of memory. You could be setting yourself up for nothing but headaches.

Edit: I also see in your link your gaming PC is running a matched set of G.Skill rip jaws
Open-loop 6600K@4.7GHz+GTX 970 in a Fractal Design Define R4

I also see your post in your hobby PC states "the Sabertooth X58 hated the mix of RAM sticks"
Air-cooled X5660@4.4GHz+GTX 970 in Silverstone RL06WS

Memory is guaranteed in the form sold. Running a "1333mhz ram,(its 4+2+2+2)" setup is asking for poor slow performance.

I suggest getting a 2x8GB 1600MHz kit of two for a i7 4770k. You can use faster memory for overclocking too.

Take a look at my signature computer I nicknamed "Gramps".
RAM installed:
2x F3-1600C9Q-32GXM (Yes, 2/4 of the original quad-stick kit)
1x F3-1600C9D-16GXM (Yes 1/2 of the original dual-stick kit)
2x F3-12800CL9D-4GBRL
1x F3-10666CL9T-6GBNQ (Yes, 1/3 of the original triple-stick kit)

Operation mode: Triple channel
Performance impact: Within margin of error (~1.2%)

They're all running at DDR3-1600 with tighter primary and secondary timings. Another point is that this platform, X58, doesn't officially support 8GB DDR3 sticks but I know after reading the tech specs for the Xeons (which the i7-900s have the same IMC) that they do support Low density (dual rank) 8GB sticks.
I've been doing things like this for a while. The notion that there is a performance impact by mixing sticks is fake news. The only time there is an impact is if one of the sticks is significantly slower rated than the other (DDR3-2133 vs DDR3-1066 for example) or one stick has worse timings than the other at a given speed (which Flex makes the system switch to the best matching timings).

I also see your post in your hobby PC states "the Sabertooth X58 hated the mix of RAM sticks"

Well ya that's going to happen when you're running a 10 year old DDR3-1333 stick at DDR3-1680 with tighter timings.
FYI: You cherry picked out that statement. The following sentence:

My old P6T was fine with 1.56v.

tells you that they already needed extra voltage and the Sabertooth X58 itself wasn't playing as nicely with the mix as the P6T which is where the comment is derived.

I wasn't trying to "cherry pick" anything. I'm just pointing out that mix matched pairs of ram are not recommended and can possibly cause the issues he's having.
