I've been looking at 970 MBs and checking the maker websites for what they will take for memory. It's kinda confusing. Can someone give me a breakdown of 1600 versus 1800 versus 2000, 2300, etc. Thanks!

With older mobos in particular it gets harder and harder, Kingston has their Fury line of DRAM that runs off PnP which is basically only supported by the 1155 and newer mobos, they list the compatible mobo chipsets on their web site, others run into problems with older mobos like socket 775 and 1156 which are geared to the low density memory chips (2Gb and smaller) where most all newer models of DRAM use high Density (4Gb) memory chips. You can check a mobos QVL, or (and take this with a grain of salt) ask in the forums (though many in the forums all over still believe DDR3 is DDR3 and all DDR3 will work with anything ;) ), you can check with the memory manufacturers direct, i.e. Gskill has a rep who pops in here at Tom's you can PM...

Bigger is faster. The impact of this ranges from important to insignificant depending on what you are doing. In gaming, the impact on average fps ranges from 0.1 to 10+%. The impact on minimum fps is more significant and when SLI / CF is involved more important again as at some point in many games the cards stop being the bottleneck

here you see average fps at both ends of that spectrum.... Metro does 0.1% .... F1 exceeds 11% going from 1600 to 2400

here's "makes no difference" (+11.3%) with a discrete card

CPU Intel Core i7-4770K (Haswell): 3.50 GHz, 4C/8T
Overclocked to 4.50 GHz (45 x 100 MHz) at 1.25 V Core
CPU Cooler Thermalright MUX-120
Motherboard Asus Z87-Pro: LGA 1150, Intel Z87 Express, Firmware 1707 (12/13/2013)
Graphics PowerColor PCS+ AXR9 290X 4GBD5-PPDHE: 1050 MHz GPU, 4 GB GDDR5-5400

1600 - 159 fps
2400 - 177 fps

His eyeballs won't see it, only in the benchmarks will it make a difference.

It all depends on what you do with the rig, even in gaming. Where faster DRAM really shines is when multi-tasking and using memory intensive apps like CAD, rendering, VMs, imaging, etc or simply using large data sets. You can also see differences based on the platform being used - touched on that in my article here:

http://www.tomshardware.co.uk/dram-benchmark-fluctuations,review-33154.html

AMD has weaker MCs and can't utilize DRAM as well as Intel, so using faster DRAM can be more important with a AMD build that on Intel. What CPU will be used (it will determine the data rates you will likely be able to run

2% doesn't get noticed; 11% does. By comparison:

The difference between a 970 and 980 is 13%
The difference in boot time between a SSD and SSHD is < 6%

And the differences in minimum frame rates, especially in SLI / CF are much greater

In answer to you question, I do moderate gaming (Skyrim, LOTRO, couple other MMOs),
Web design, game programming with Unity3d, 3DStudio Max, music, and video editing.
Looking into the FX8350 or 8370 8 core.

Best buy @ 2133 right now are these:

Partpciker as usual screws up link and sends you to model Model 996996
http://pcpartpicker.com/part/mushkin-memory-997121F

Mushkin Enhanced Redline 8GB (2 x 4GB) 2Model 96121F
EDIT: Mushkin Enhanced Redline 8GB (2 x 8GB) 2Model 96121F
DDR3 2133 w/ 9-11-10-28 timings
http://www.newegg.com/Product/Product.aspx?Item=N82E16820226687

There's 1 or 2 cheaper sets out there but with crappy CAS 10 or even 11 timings. Lower CAS will come in real handy in 3D Studio max, video editing

My bad, missed that, saw your suggestion

"Best buy @ 2133 right now are these:

for 2x4GB Mushkins as that last post thought looking for 2x4GB

Your link goes to newegg home page

Thanks or catching the typo.... if you use the pcpartpicker link

http://pcpartpicker.com/part/mushkin-memory-997121F

It shows 16GB (2 x 8GB) DDR3-2133 Memory

Unfortunately, clicking on the newegg link from partpicker takes you to a 2x4Gb set. Not unusual for the pcpartpicker folks

Nevertheless....The Mushkin 2133 Redlines remain the best 2133 buy right now, especially for his app uses.

Thanks!
Only trouble is Asus only lists certain ones, one of which isn't even available for purchase. Seems rather silly.

Thanks! So how do you know that what you want to buy is going to work correctly?

I try and keep up with DRAM so can PM me if you wish.

Most DRAM and mobo manufacturers have working relationships where they exchange products for testing....however the actual testing especially by mobo manuafactuers is often limited by time constraints among other things. If you think about it, say a Haswell mobo, running DDR3 - just at NewEgg alone they offer in excess of 1,000 different packages of DRAM (which doesn't include the manufacturers they don't carry, nor the individual lines (models) of DRAM they don't carry. Nor does it take into account models of DRAM that change (i.e. Some line of DRAM that used to be made with 2Gb memory chips are now made with 4Gb chips) - or instances where a line of DRAM used say Micron memory chips, and changed to Samsung or another brand (which happens all the time)).

Since both certify compatibility, it's easier for one to just test on their own and certify rather than pay the other to test. I haven't heard of anybody paying for testing between the two in years, closest being Intel that has a cert program DRAM makers had to pay to have Intel test, and think that has gone by the wayside
