Here is my ram. Dont know where you are finding $140, unless yo are going for 16gb

Your RAM is DDR3-1600, I'm looking at DDR3-2133. :/

Ok, so here's the conundrum. The RAM I have on the list has a CAS latency of 9, which I was told was better lower.

I've limited my RAM search to 1.5V and under as per the recommended voltage for the CPU, and I'd have to pay $140 for anything with a CAS of 9.

Is 11 that bad?

Not as far as I'm aware, no. Generally speaking the timings on RAM only seems to matter to the absolute enthusiasts, the people who actually bother to OC their RAM. Of course it's nice to get tighter timings but so long as you aren't running DDR3 with DDR4 timings you shouldn't have any problems whatsoever.

Your RAM is DDR3-1600, I'm looking at DDR3-2133. :/

Just get some 1600Mhz, you won't feel any noticeable difference and you'll save yourself buckets of time by not worrying over something completely irrelevant

Why though? its such a small difference.

Was just listening to people who were helping. :c

Alright, so what is more important, the mhz or the CAS latency?

Neither, get the fastest you can afford with the highest combined capacity (up to 16GB over 4 sticks if you really need a lot of RAM or up to 8GB over 2 sticks if you're just an average user) and best speed with the lowest timings possible while being supported by your CPU.

It's very much the middle piece of the jigsaw puzzle, it will always fit if you put it in last.

You also have to count in voltage. generally 1.5 or lower is recommended for DDR3.
But besides that, CAS and mhz both don't have a big impact, unless its like 1600 and 2800 or something like that. A higher cas with a higher mhz balances out with a lower cas with a lower mhz. I mean, look at DDR4. The cas is very high, and so is the mhz. Some people have done tests with similar setups and funny enough for gaming, 1600 with CAS 9 was better than 3000 with like 13 CAS (though it was a very small amount)

Honestly, just make sure its at least 1600 and make sure the voltage is 1.5 or lower and you should be good. also, stick to trusted brands, usually the higher rated ones.

Also, you dont need more than 8gb if you are just gaming and not doing lots of video/art editing.

This is pretty much the last piece I'm trying to put on my list. I would totally go up to 16GB if I had the money, but I guess 8 will do. Already a step up from the 4GB I have now.

Going off of this:

To put it on simple maths:

The frequency is expressed in Hertz, which means "cycles per second". So, the DDR3 2000 will perform 2000 cycles a second while the DDR3 1600 will do, well, 1600.

The CAS latency is given in cycles. So, a CAS9 RAM will take 9 cycles to respond and the CAS6, 6 cycles.

Now putting it together: the DDR3 2000 CAS9 will take 9/2000 seconds, which is equal to 0,0045 seconds, to respond while the DDR3 1600 CAS 6 will take 6/1600, which is equal to 0,0038 seconds, to respond. Thus, the 1600 one is faster.

Less RAM sticks generally means less load to the memory controller. So, 2x4GB is better than 4x2GB.

I should get this:

A 1600mhz with a cas of 7, making it about .0005 seconds faster than a 2133mhz with a cas of 11.

Right?

I was almost sold on a Corsair keyboard but saw a disturbing number of reviews saying many of the LEDs died quickly and in some cases the whole keyboard stopped working...now I'm not sure what to turn to

Which one was it?

Like I said, just pick whatever seems the best for your system. Picking RAM is nowhere near important enough to be making such irrelevantly precise calculations, as long as it suits your system and it has good reviews then that's all you need.

The K70 and K95 both have reports of it happening

Alright, I settled on a certain one. Thanks guys. :)

Haven't seen any reviews saying the K95 has any problems on UK parts retailers, maybe check other sites and see if it's consistent over a large span of time. Probably just a bad batch.

[Ninja Decoy]

Yeah, and yet they are still the highest rated mechanical keyboards.

Honestly, I think ill wait for the RGB series to come out.

[Regulith]

I guess the issues with the K70 are rare, I think I've made my choice

[Foxscotch]

If would be better to get 4x4 if you are stopping at 16. If you plan on going to 32, get 8x2.
Though, you dont even need 16gb unless you are doing serious video editing or digital art.

I'm not really planning on anything. it was mostly a hypothetical question because I was curious
I don't think I do anything that would use more RAM than I have

I went and felt some switch types today and I think I'll go with something that uses cherry browns

where?? I wanna do that but I don't wanna have to buy one of those little sample things
