So I'm looking to build a new gaming computer and after much research decided to move from Haswell (i7-4790k) to the Skylake (i7-6700k) and since I don't see DDR4 to be much of an upgrade right now other then lower power consumption, I thought I'd stick with DDR3. I only found one mother board that supports DDR3 for Skylake Asus Z170-P D3, and as for ram this it what it comes down to.

1. RipjawsX 3-17600cl7d-4gbxhd

2. RipsjawsX f3-17000cl7d-4gbxhd

3. F3-12800CL7D-4GBRM

Same as the 2200? RipjawsX PC3-17600 BPIS

The fastest one being the 2200 with CL7 at 3.18ns

7/2133 * 1000 = 3.28ns

7/1600 * 1000 = 4.37ns

I cannot find the 2133 or 2200 anywhere. Newell says Out of Stock. Mostly just looking for input on the best ram to use for this setup.

CPU: i7-6700k Supports DDR4-1866/2133, DDR3L-1333/1600 @ 1.35V : Does not support DDR3 @1.65 ??

MB: ASUS Z170-P D3

SSD: Samsung SM951 M.2 128GB

HEATSINK: Cooler Master Hyper EVO

CASE: Corsair Carbide 200R

MEMORY: ???????

VIDEO CARD: Onboard Intel HD 530

Thanks

You said "Gaming" but listed onboard graphics as your video card...

I am very much hoping this is a typo, and will respond under that assumption...

You will not see any improvements in your gaming capablities by upgrading to the system you described.

The CPU is a very small factor in gaming today. You might get an extra 1 or 2 FPS if anything.

If you want to upgrade your system for gaming, I would suggest a high end video card, rather than a whole new high end computer.

Check out this article, it applies directly to what you are trying to do. Pay special attention to the section about gaming with a discrete graphics card.

What graphics card do you have currently?

If you are gonna do a completely new build, go with 16gb of DDR4, it is faster and I think Fallout 4 will need 8gbs. Then get a GTX 980Ti. The setup otherwise looks good.

lol.... just noticed my link got cencored... not sure why; it wasn't profanity lol

Anyway... you might have to do a google search for that article.

Also, I just noticed you were calculating the response times for those memory kits. Latency is important, but so is bandwidth. You want to find a nice balance between the 2. (also, your math is slightly off, you need to use half the clock speed since this is DDR)

For example, you can get DDR4 with Cas latency of 16 at a clock speed of 3466Mhz which would get you 9.23ns latency compared to 6.56ns in your quickest example. But when we look at Bandwidth, we are looking at 27.7GB/s with DDR4 vs 17GB/s with DDR3.

Also, the technology is only going to get better... so you would be better off investing in the technology now so You can take advantage of it more in the future.

Absolutely no reason to upgrade your CPU

especially for just gaming

I would wait heck maybe 4 years before thinking about it

the reason that there aren't alot of ddr3 z170 boards is because the high voltage of DDR3 can HARM your cpu

Agreed, and good info on the voltage... didn't even think of that.

4 years might be a stretch, but yea, you will need a better graphics card long before you need a better cpu...

BUT DX12 has the potential to be a game changer and this conventional wisdom could become invalid... I am very interested to see what the future holds :-P

If you REALLY want to rebuild your system, go with newer tech, not older. Tech only goes forward, not backward.
