CAS 8 worth 50$ more than cas9?

[Noitidart]

Hi all,
I was going to go with two sticks of 4gb for a total of 8gb. I heard this was better than 4 sticks of 2gb. So then i was deciding between these two:
Opt1 = 8-10-10-27 | 1.65v | $145 | Corsair Vengeance Pro
Opt2 = 9-10-10-28 | 1.60v | $95 | Mushkin Redline
Opt3 = 9-11-10-28 | 1.65v | $90 | GSkill RipJaws X


So is the cas 8 and 4th being 27 much better? Does 9-10-10-28 vs 9-11-10-28 make a noticeabl difference?

It also depends what frequency the RAM is running at. You probably won't notice the difference between cas 8 and 9 at the same frequency. The Vengeance Pro is more expensive because it is made to be overclocked like the G.Skill Trident series. I would get the G.Skill RipJaws.

CAS 8 is better, but the price is much higher. A high frequency is more important than low latency these days. CAS 8 will have a lower overall latency. 9-10 and 9-11 is about the same, so get the one that is cheaper.

I would recommend looking into modules that use 1.5v or lower. Also it depends of the clock speed of the memory, CL8 is very good for 1600/1866Mhz ram

Those are better.

Memory: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory ($81.00 @ Newegg)
Memory: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1866 Memory ($89.99 @ Newegg)

Or this CL9
Memory: Corsair Vengeance Pro 8GB (2 x 4GB) DDR3-2133 Memory ($139.99 @ Newegg)

What mobo and CPU....and what freq are you looking at

I'm having a AsRock Extreme6+ FM2A88X with AMD 7850K

my use is for vmware of 3 os'es (mac, linux, one other) and win 8.1 install. I also watch lots of streaming sports and make video clips. Lots of video clips of programming for tutorials.

So Im looking at 2133mhz as thats max supported by 7850k

not looking to overclock

Honestly the difference between 9 and 8 isn't worth the $50. I'd say just go with Ripjaw.

 

[Tradesman1]

Of those go w/ the Ripjaws or take a look at the GSkill Snipers in 2133/9 good with your mobo/APU combo

+1

Thanks all very much. Can someone explain the benefit of the snipers over the ripjaws? ripjaws seem to have better timings. the snipers are just .05V less ussage

There's a variety of RJ X sets both the RJ X F3-17000CL9D-8GBXM and the SNipers F3-17000CL9D-8GBSR , come at 9-11-10-28, 1.65, of the two the Snipers tend to have a hair more OC headroom
