CMZ8GX3M2X1600C7R Modules not listed on products page

I'm getting ready to upgrade my system from 4GB (XMS3) to 8GB CMZ8GX3M2*1600C7R. However, I cannot find this part number (CMZ8GX3M2X1600C7R) on the Corsair product pages. I tried search and even looked through almost every 1600 memory module. The closest thing I can find is CMZ8GX3M2A1600C7R.

Newegg no longer sells the "A" revision and only has the "X" revision. I'm assuming this is newer.

Is it worth the extra 7 bucks or so to have 7-8-8-24 over 8-8-8-24? (comparing CMZ8GX3M2X1600C7R vs CMZ8GX3M2A1600C8R)

I'll be installing this in my Gigabyte GA-870A-UD3 (rev 2.1)

I would not suggest mixing memory, if you want to go to 16 Gig of memory you should replace what you have now with a 16 Gig set of memory.

[WayneC0rsair]

Wow, that answer was completely not even what I was asking about. But I'll let it slide this time since I think you replied to the wrong thread somehow.

 

To clarify things, I'm upgrading my existing 4GB to 8GB using the part number that I listed. NOT 16GB.

If it's really going to be that difficult for Corsair to answer this question, I can always buy memory from a competitor.

You won't notice the difference between CAS 7 and CAS 8 in almost any application, but in benchmarks you'd notice a slight difference.

[RAM GUY]

I took it that had 8 gig of that memory and you wanted to add more to what you had installed. But wired posted is correct. And all of the Cas 7 parts are no longer in production is why you can find them.

Oddly enough, this memory I bought years ago is still being sold, lol.

Even though this "X" revision is "no longer produced", there should still be a data sheet available for it because there IS a page for the "A" revision.

I called Corsair today and didn't get anywhere.

 

 

And this is a bit confusing to me (this is my current memory specs)

SPD Speed: 1333

SPD Latency: 7-7-7-20

Tested Speed: 1600

Tested Latency: 8-8-8-24

 

I've never been able to get this memory to run at 1600, but I'll take the 7-7-7-20/1333 rating any day for the other.

[RAM GUY]

So now I am little confused as to what it is exactly that you want?

Can you be a bit more specific?

[WayneC0rsair]

Mainly looking for a pdf/datasheet/manual for part CMZ8GX3M2X1600C7R so I know exactly what I'm buying. SPD vs tested isn't listed on newegg's site. They give only one rating.

[RAM GUY]

I am sorry but we no longer provide data sheets but if you click on Tech specs from the Product page all of the information is listed that is available.

This is from a resellers site that still has them:
