2133mhz Ram Test Results

Yeah, have to agree. My hyperX 2133mhz ram is stable also.

I can chime in. It is stable for me as well. So far I have done some Photoshop work i parallel to Handbrake encoding in the background. RAM utilization was around 11GB (out of 16).
 
A little off topic...

I received the 4 x 8 GB HyperX 2133 MHz today and at first put two of them in my 17" MacBook Pro Late 2011, since I recognized before it was able to handle the 2 x 4 GB 1866 MHz which came with my iMac.

It is stable and seems to boot and run much faster than with 16 GB of 1333 MHz RAM.

With what kind of benchmark I can check quickly if this isn't just imagination?

I think geekbench, I've heard of memtest too but I've never tried it

memtest86+. Actually not a benchmark, it just puts your RAM through as many usage scenarios as possible. It's great for testing stability or trying to isolate RAM in hardware testing if you suspect an issue. It's not a program you can run from OS X though. You boot into it (Linux) by installing it on a USB drive.
 
I've been using the HyperX 2133 on my system non-stop for a few days now, mostly standing up and tearing down big VMs all day (vagrant) and everything has been solid. Machine is fantastic. Overkill for what I do, but I maxed out hardware for the occasional game, not my day job.

@ericv just up this page you said it was the hyperx HX321LS11IB2/8 you got, right? that seems to be 11-12-13 from the kingston website. the 11-11-11 stuff is the HX321LS11IBK2/8 (extra K in the name) which seems to be discontinued for some reason. just 100% checking which one you bought before I spend.

Is this the faster 11-11-11 stuff?

http://www.ebuyer.com/666149-16gb-2...2-1-35v-hyperx-impact-black-hx321ls11ib2k2-16

Edit: just noticed the model number (hx321ls11ib2k2/16) and looked it up on the Kingston site and it's 11-12-13.

So what's the difference between the first two...

HX321LS11IB2/16 11-12-13
HX321LS11IB2K2/16 11-12-13
HX321LS11IBK2/16 11-11-11

😵

The Kingstons are listed as 2400mhz compatible which the CPUs in the iMac late support

The memory should auto over clock to that. Strange it only overclocks to 2133
 
Hi @All.

I study every forum and site that google can give me about Ram for iMac 5k late 2015.

I ordered first Crucial BLS2C8G3N18AES4CEU Ballistic Sport http://www.amazon.de/Crucial-BLS2C8...ds=crucial+bls2c8g3n18aes4ceu+ballistix+sport this was on Saturday.

After i ordered the ram i found this thread here.

I ordered yesterday this here Kingston HX321LS11IB2K2/16 16GB 2x 8GB, 2133MHz, CL11 http://www.amazon.de/Kingston-HX321...qid=1448974650&sr=8-1&keywords=hx321ls11ib2k2

Today both Ram´s are here fast shipping from Amazon.

I´m only try the Ram from Kingston! The Crucial one goes unopened back!

2133 MHz is a beast! The best you can actually become.

I have some Pictures for you.

I'm adding myself to the chorus of people who have successfully installed 2133 MHZ memory in their late-2015 iMac.

In my instance I choose to remove the two factory 4GB 1866 MHz modules and use four 8GB 2133 MHz modules instead.

Kingston Hyper Impact HX321LS11IB2K2/16.

BTW...

New iMacs are appearing on geekbench.com.

With a multi-core score over 20,000 it makes iMacs with 2133MHz memory slow by comparison.

Just received my new 27 5k. I can confirm that the Kingston 2133mhz RAM works fine at the moment!

Got my Kingston Hyper X installed in my 4ghz 395x 1tb SSD iMac, I'm liking the results!

--- UPDATED GRAPHIC WITH BETTER RESULTS ---

Can you post your 32-bit results?
[doublepost=1457527093][/doublepost]I'm getting significantly higher than you with almost the same spec iMac - I'm on a fusion rather than straight SSD.
Overall 64-bit is 4693 and 17992.

Thank you. I tried Geekbench now.

Sorry for being off topic, but I am really surprised. (iMac is following later)

There's quite a difference between the 1333 MHz and 2133 MHz RAM on my MacBook Pro Late 2011. I did not expect that it is even compatible with it.

Any result with your iMac?

I had some apps running which I quit, out of 4 tests my highest was 4681 and 17873. Reposted my graphic.

12 points on Single core is significant in your eyes?

.25% Higher to be exact is not a SIGNIFICANT HIGHER score...
