My (2013) PC needs (32GB) RAM upgrade and I wonder if 2400 Mhz is too much for my setup.

Hello everyone.
My (2013) PC needs (32GB) RAM upgrade and those are my options:

a. 120 EUR: 1866MHZ DDR3 32GB (4x8GB) G.SKILL Sniper F3-1866C10Q-32GSR
b. 200 EUR: 2400MHZ DDR3 32GB (4x8GB) G.SKILL TridentX F3-2400C10Q-32GTX

a. 1866 CL10-11-10 1.50V 4x8GB DDR3 vs
b. 2400 CL10-12-12 1.65V 4x8GB DDR3

My questions:
- Can I / improve the overall system performance with XMP 2400MHZ @ 1.65V - with my current (2013) setup?
- Are there some bottlenecks that I can`t see?

I do prefer system stability but I wont mind some extra breathing room.
This PC is used for Office/NET tasks, but mostly for Microsoft Flight Simulator 2020.

My (2013) setup:
>ASUS Maximus VI Gene Gaming MB with RAM support for: 4 slots/DDR3/240-pin DIMM /Max Speed: 3000 MHz/Max Capacity: 32 GB/Max Channels: 2/ ECCt: No
> ASUS Maximus VI Gene Gaming MB Memory Setup Guide ;
>Currently installed 16GB (2x8GB) Corsair Vengeance Pro DDR3 DRAM 1866MHz C9 Memory Kit CMY16GX3M2A1866C9R ;
>CPU: Intel Core i7-4770K Processor (8M Cache, up to 3.90 GHz) ;
>GPU: Founders Edition Nvidia Geforce GTX 1080 Ti 11GB GDDR5X ;
>SDD: Samsung 970 EVO NVMe® M.2 SSD 1TB ;
>PSU: 750W Enermax Revolution

Thank You!

I'd go with the 1866 one, the other one you really got to juice the ram way to high for stability. The faster speed isnt going to make much of a difference in anything beside benchmarks anyway.

With four sticks of 2400, could you even get them all to run at 2400? I know with systems of ddr4, getting four sticks up past 3600 sometimes doesn't work even if they are supposed to go faster.

I'd probably just stick with 1833...not sure it will matter.

Thank you for your replies.

> Will they run @2400 Mhz? Probably yes, my MB supports this and others have reported this.
> Will my RAM remain stable @ 1.65W for 99% of the time used? Probably no.

So, is the risk worth taking? imho probably no. Not at all.

Does RAM Speed Matter? DDR3-1600 vs. 1866, 2133, and 2400 in Games​

> "In the end, the chips fall as one might expect, at least in terms of order. Yes, the “fastest” kit is actually fastest, and the “slowest” kit is actually slowest.
> Even so, the difference are fairly small – they are just 1.4% in terms of average framerates and 3.9% in terms of minimum framerates.
> In between, the 1866 kit has a small lead on the 1600 kit, and the 2133 kit pulls just ahead of the 1866 kit.
> The outlier is the DDR3-2400 CAS 11 kit, which had the bad result in Metro: Last Light discussed earlier.
> That really brought down its overall minimum framerate score, although its average framerate is still quite strong."

I always ran DDR3-1600 on my 4770. Bandwidth wasn't as big an issue back then as it is now. I'd go with a kit that has as little latency as possible.

I would just try to find another set of the 2x8GB RAM you currently have.

"RAM true speed". Don't know if this is still valid. Please correct me if I am wrong.
*1866/10 = 186 vs 2400/10 = 240
*1866 is overclockable

My (newegg) problem: 1.50V vs 1.65V
1866 / 1.50V reviews: < 3% DOA or stability issues and >70% with 5*
2400 / 1.65V reviews: > 40% DOA sticks and/or BSOD stability issues.

 

[bluestang]

Well, then your current RAM is 1866C9 and 1.5v...so just buy another 2x8GB kit like I said and be happy. That 4770K isn't going to notice the difference and neither are you.

 

[dasa]

If they are both free or near free I would go with the 4x8GB 2400.
1600 to 2400 with some tuning can improve CPU performance up to 15% in a CPU limited game like FS.
The MB is about as good as it gets for running 4 high speed sticks of RAM and the 4770K can run well over 2400 while 2600K was limited to 2133 and 3770K was borderline 2400.

But if the RAM is costing you anything you are better off buying new CPU\MB\with DDR5 RAM if you want more performance the difference will be massive. Especially if your running that 1080ti at 1080p and running optimized detail settings not maxing it out.

What are you on about?
Please settle down and have some more posts before you feel the need to be whatever is.
Thanks

It is a rough calculation to give an idea of how frequency vs cl comes out as far as the sticks latency goes and yes that is correct the 2400 kit with the same cl will have lower latency.
8.3ns vs 10.7ns

Thank you, that was my point.

Thank You all for your help.
I ordered a 1866MHZ DDR3 32GB (4x8GB) G.SKILL Sniper F3-1866C10Q-32GSR. Those reviews scared me a lot.
Thanks again.

*No additional upgrades for my current PC - I already started browsing for my next new build.
*PS: My old RAM (2x8GB) Corsair Vengeance Pro DDR3 DRAM 1866MHz C9 Memory Kit CMY16GX3M2A1866C9R ) will be used appropriately on another PC.
