(RAM) Corsair Vengeance vs the (better?) Kingston FURY Impact (Laptop)

[Ruenis]

Wondering if the Kingston FURY Impact SODIMM RAM - DDR4 2666MHz CL16 - is generally better or worse than the often hailed Corsair Vengeance SODIMM RAM - DDR4 2666MHz CL18 - or vice versa? 🤔

Don't bite. I was born in 2019... :P ( /s )

Same MHz CL16 is faster then CL 18.

I was mislead by a YouTube video ending on that Corsair was Number 1. I was always one to believe the lowest Cas Latency meant the fastest ram (that is, with the same memory bandwidth), but wasn't tech savvy enough to understand the whole picture.

What you said is generally the case, right? o.o

[Ruenis]

I mean the FURY Impact is even more expensive, if that signifies anything.

[Rumpelcrutchskin]

Yep, when it comes to CL lower is better.

If the MHz is same, for instance 3600 MHz CL 16 is better then 3200 Mhz CL 16.

Can try https://ram-comparison.com/

Can look up the chipsets details. Dual rank vs single rank. Chip manufacturer samsung , hynix, micron, etc... and maybe die model (a,b, etc....).

More of min/max stuff than normal.

If it's just a slight difference grab the Kingston otherwise go for cheaper as it's not worth it you'll not be able to tell the difference in performance.

If this is RAM you intend to plug and play (which I'm presuming is the case given it's SODIMM for a laptop) as opposed to tweaking yourself, then the deeper details, like what die it uses, is of far less consequence.

What matters most and frequency and timing balance. Other stuff (rank, density) matter too, but only to a point. Like is the latter also x8 instead of x16 (this refers to density, not capacity), and dual rank compared to single rank? These aren't details to obsess over all the time, but there could be intangibles might result in why the latter is more expensive. Or, the latter is just more expensive because... it is. Not all options are equal values and maybe it's simply the worse deal. Do you have links to both exact memory models?

Going solely off of the information you did provide, as both RAM is 2,666 MHz, then the one with CL 16 is better than the one with CL 18 as a few other posts have said. And if the faster one is ALSO cheaper, then there's little question as to which is the better overall choice. But, you won't really see a major difference between those two in real world use though. Benchmarks will be where it is observed, and you may as well take the cheaper and faster option, but they won't be much different. Both of those are also generally considered on the slower side in DDR4 terms compared to RAM available today.

Here are links:

The one I suppose is the best, the Kingston FURY Impact (CL16, 2666MHz, Single Rank): https://www.amazon.com/dp/B097QMSLKL/

The Corsair Vengeance (CL18, 2666MHz, Single Rank): https://www.amazon.com/CORSAIR-Vengeance-Performance-260-Pin-CMSX32GX4M2A2666C18/dp/B01BGZEVHU/

Here's a THIRD contender since I last posted this - dual rank ram, and the cheapest, at CL19, and 2666MHz. Timetec: https://www.amazon.com/gp/product/B07H4YBTYY/

I'm undecided because people say Corsair is the best, the Kingston LOOKS like the best, but the Timetec has the best rank.

If you cared about speed you wouldn't be looking at 2666 RAM. These are all the same, stop thinking about it so hard.

2666MHz is my maximum bandwidth, lol.

Okay, so all three of those are 2,666 MHz. So all there is to compare is timings and price (and rank I guess).

I notice it's becoming more common to not disclose the CL besides the first one, probably because it's more common for RAM to not have flat primary, secondary, and tertiary timings by default (this used to basically be a given). This is common with Hynix die RAM especially. Nothing wrong with it; I have some, but it's making it harder to compare when they don't list them all.

The Kingston Fury have timings of CL16-18-18[www.kingston.com], with no mention of the forth (probably something like 39, or maybe 42 though). Price is $114.

The Corsair Vengeance has timings of 18-19-19-39. Price is $92.

There's this[www.amazon.com] which is slightly better timings (flat CL18, except the last is CL43) at $87 (Newegg and even Micro Center are listing $95 for it). I won't admit I might not be slightly biased towards G.Skill, but it competes with the options you're looking at in terms of price and specs. I can't find if it's single rank or dual rank though, but it's not a huge deal if all the above are single.

I'm going to presume to Timetec kit is something like 19-22-22-42 timings , but only the first is listed again. If it's flat 19 and the last is like 39 I'd say it's the best option. Otherwise it's the slowest, but it is dual rank, and also the cheapest.

Honestly there's a case for any of them but I'd probably rule out the Kingston and pick a favorite/preference from the other three. Roll a die even, or narrow it to two and flip a coin, haha.

That might simply be what the laptop will max out at, and there's nothing wrong with getting the best performance for price option even on stuff that isn't faster.

I notice that 3200MHz ram is cheaper than 2666MHz ram, and I've heard that installing ram at a speed over your max bandwidth will only downclock it to your max bandwidth.

I also get this feeling that if you have ram over your max bandwidth, there would be an element of "greater smoothness" there, but I could be wrong. Would you recommend going for the cheaper 3200MHz stuff? Oh, and thanks for the reply!

[DevaVictrix]

Your board will almost certainly use the lowest clock speed if you have dimms with different frequencies.

The higher rated dimm (when run at a lower frequency) will have wriggle room for reducing latencies but it’ll only be possible if your dlower dimm also support the lower latency.

Best thing to do… leave it alone! The gains are marginal and risks of instability real.

[_I_]

you can always run ram slower or use higher timings

speed / cl = performance, higher = better

That's true.

No, because 2,666 MHz is 2,666 MHz regardless of how much faster the RAM can or can't run. It will be the same.

That being said, if the faster stuff is the same cost (or cheaper), then you may as well take it.
