Ram compatibilty

[grimmjow660]

My buddy offered to sell me his 16gb set of Ram, he bought the wrong set. He told me $100 for this

I already have 8gb 1600 G SKill Ares ram and have been wanting to upgrade to 16 for awhile.
My cpu is i7 4790k and mobo Asus Z97-AR.
Would there be any problems with the compatibility?

The new RAM would run at 1600, if you keep your old RAM.

I don't plan to

I don't plan to

Then everything should be fine.

DDR3-2133MHz with CAS 9? For $100?

DO IT.

 

You can then sell your existing 8GB kit and easily get $50-$70 back.

$50 for 16GB of RAM. Win-Win-Win...for you

I've never understood the CAS latency and how it makes a difference?

Dude, CL9 2133........Do it, that's a damn good deal, The lower the cas and the higher the speed typically means more expensive. My Viper Extreme ram is also 2x8GB but its a CL11 @ 1600 at stock so, that deal you got offered is dam good... I seen a G. Skill kit that's 1600@CL9 for 165 bucks at NCIX so ether NCIX is ripping ppl off or you got a awesome deal.

the lower the latency the better...when you divide the clockspeed by the CAS latency you get a number, the higher this number is...the faster the ram sticks.

In your case 2133/9= 237...very fast

 

For example 1866 CAS 10 vs 1600 cas 9:

1866/10=186.66

1600/9 = 177.77

So 1866mhz CAS 10 should be slightly faster.

 

2133mhz CAS 9 is VERY good for DDR3 sticks...if they can run stable at their advertised XMP speeds (not always the case) they should be pretty fast, remember to enable XMP profile 1 in your bios otherwise they will run at 1333mhz CAS 10 or some shit like that.

CAS (tCL) latency is one of the memory timings for DRAM. 

It is the time delay between each sending and reading command.

 

The standard JEDEC timings for DDR3-2133MHz is 11-11-11-## (even goes up to 12 or 13).

CAS 9 is pretty damn good compared to that.

So with a CAS latency of 9 and timing of 9-11-11 and voltage of 1.6v, that set of 2133 Ram is very good?

yes it is...very fast sticks indeed.

If you look around, a lot of DDR3-2133MHz are CAS 10 / CAS 11 with 1.6V.

CAS 9 will typically require 1.65V.

You can have a look around G.Skill / Kingston / Corsair's website.

Thanks guys.
