Mixing RAM and HDMI 4k cable..

[rain_6]

I need to get more RAM for my computer, I have two 4gb 2400mhz DDR4 corsair sticks and I want to buy two more so I have 16gb total. Will anything happen if I install them?

I'm also getting a 4k monitor and I was looking through HDMI cables on amazon and came across this

https://www.amazon.co.uk/HDMI-Cable-2M-Connectors-PlayStation-Silver-Black/dp/B00NQ9OQU2/ref=sr_1_1_sspa?s=electronics-accessories&ie=UTF8&qid=1514916088&sr=1-1-spons&keywords=hdmi+cable&psc=1


Not sure if these are scams and they're just normal HDMI cables or if they are actually made to support 4k, Any help? Thanks

Mixing RAM may or may not work, try it and see if it works.

As for the cable as long as it is HDMI 2.0 it will support 4K/60hz, with the amount of reviews they seem legit.

On mixing RAM: Since DDR3, it's been a crapshoot. This is why they now sell RAM in kits of two or four matched sticks, which have been tested together. If you mix RAM, even adding sticks of the same make and model, they may
1) Run nicely with your existing sticks
2) Require timings be relaxed and possibly voltages increased to run with your existing sticks
3) Not coeexist with your existing sticks.

I personally am running two separate pairs of slightly different DDR3 with success, but you have to accept the risk to try it.

Unless you are buying a TV and not an actual PC monitor, stick to DisplayPort instead of HDMI. Either way, unless you buy a bargain-bin brand display, it should include a cable for every interface in the box (if Monitor), or at least 1 HDMI cable (if TV).

Mixing RAM: Experience says you seldom run into errors. The vast majority of the time you probably won't. There are cases where it could though. It's a crap-shoot. If they are not the same speed and/or timing, you'll initially have to start with the slowest speed and timing between them. Previous to my current build, I was running a DDR3-1600 4GB ECO kit (DDR3L voltage levels to full 1.65 volt levels) and DDR3-2133 8GB kit together... at DDR3-1600, the 1.5v level, and the slower of the timings between the two with no issue.

HDMI Cable HDMI cables work with digital level voltages. So, as long as it supports, at a minimum, the required HDMI standard, even a super cheap cable will work. Just don't go too cheap for lifespan reasons.

You need a "high speed" HDMI cable. Other than that, any HDMI cable will do.

Corsair guarantee memory in the form it is sold in and not by matching up identical part numbers.

If you go ahead with adding extra memory you may find you have to run it at a slower speed, relaxed DRAM timings, and increased DRAM voltage to get it to work.
