Did You Find It?

2666 mhz ddr4 dimm ram | Newegg.com (2024)

FAQs

Is DDR4-2666 enough? ›

2666 WILL work. You will get small levels of improvement with each speed increase; 3000, e200, 3600 Mhz. 3600 seemed to be, about 18 months ago, the sweet spot of price to performance ratio.

Know More ›

Is DDR4 2666MHz good for gaming? ›

Yes, 2666MHz RAM is generally considered good for gaming. While higher RAM speeds, such as 3000MHz or even faster, can provide a slight performance boost in certain gaming scenarios, the difference between 2666MHz and higher frequencies is often minimal and may not be noticeable in most gaming situations.

Read The Full Story ›

Is there a big difference between 2666MHz and 3200Mhz RAM? ›

Assuming we're talking about memory performance, the short answer is that there will be virtually no visible difference in performance. The money you'd spend on the faster memory is better spent elsewhere.

Read The Full Story ›

Why is my RAM speed stuck at 2666? ›

If there was 2666 Mhz memory installed before, that is probably what is actually the available bandwidth. It is dependent on the BIOS ROM. Did you install two new sticks or only one additional? If you left the original module in, the memory added will downclock to the lower bandwidth and that would be 2666 Mhz.

Is 32GB 2666MHz better than 16GB DDR4 3200MHz? ›

Depends on the use case scenario. Speed is just a measurement how fast RAM can access its memory. If you have 16GB RAM, it can be just enough for your needs but if you are overloading those 16GB of RAM then 32GB of RAM, even at 2666Mhz, is better to use than faster 16GB RAM. Of course, 32GB at 3200Mhz is better.

Show Me More ›

Should I upgrade RAM from 2666 to 3200? ›

16gb ram at 3200MHz vs 2666MHz, you're looking at 0.1 to 0.5% performance increase. If you normally get 100fps in a video game with 2666MHz, then you'll get like 101 or 102 FPS with 3200MHz. Until you start using ram that is rated at 4000MHz or 5000MHz, 2666/3200 is nothing.

View Details ›

What happens if you put 3200MHz RAM in 2666mhz laptop? ›

Dual channel requires both memory chips to be the same capacity (2 x 8 GB, 2 x 16 GB). Your notebook's processor can only run the memory at a max speed of 2400 MHz, so both the DDR4-2666 MHz and the DDR4-3200 MHz memory chips both automatically bridge to 2400 MHz. Hi: It shouldn't be a problem at all.

Explore More ›

Is DDR4 3200MHz still good in 2024? ›

DDR4 3200MHz RAM is a great way to balance gaming, performance, cost and compatibility. This speed is often described as a sweet spot for gamers, offering a significant improvement over low-speed DDR4 without the significantly higher price of high-speed modules.

Discover More ›

Can I put 2666 and 3200 RAM together? ›

The motherboard may support both 2666 and 3200, but not at the same time. Mixing speeds won't damage your motherboard, but as has already been said, it will lead to problems.

Discover More Details ›

What speed is DDR4-2666? ›

21300 MB/s

Discover More ›

What happens if your RAM is too fast? ›

Overclocking can cause system instability, shorten the lifespan of your RAM, and void your warranty. So, it's recommended only if you know what you're doing and are prepared to accept the risks.
