Kingston HyperX 2133MHz

The newest and fastest RAM for notebooks are just around the corner, but I am wondering if you can use it on all Sandy Bridge platforms, including all i7 CPUs?

Here is a PDF from Intel saying it is only certified for ASRock HM65 and 2920XM CPU. Is this another lazy attempt from Intel listing up what supports the RAM or is it only this CPU? The review I link to at the bottom says you can set a XMP profile and use memory multipliers, like 2630QM users do to use 1866MHz RAM.

Here is a review of the RAM (on a desktop) if anyone is interested.

I would say the RAM would work on the newer i7's, starting with the 2630QM. A couple of us Alienware boys have tested and ran 1600mhz and 1866mhz RAM with a 2630QM (the lowest SB i7), even though Intel says the top supported is 1333mhz. Not sure about other processors though. But in all honesty, I can't wait for this RAM. Hopefully it comes out soon/

 

I'm using 1600 CAS 9 RAM in a Macbook Pro (i7 2.3) myself, but there have been reports about 1866 CAS 11 (and even 1333 CAS 7) being unstable.

My suspicion is that the culprit lies with Refresh to Active/Refresh Command Time (tRFCmin)", which is 110 ns (min.) on the 1333 CAS 7 and 160 ns (min.) on the 1600 CAS 9 and 1866 CAS 11. 110 ns might be a bit too little for the CAS 7 1333 as might be 160 ns for the 1866 CAS 11, while it seems to fit the 1600 CAS 9.

So it will be interesting to see how stable this new RAM works in practice (didn't have a look on the specs myself yet).

 

In my experience laptops like to run faster ram at a lower spd profile, the one the stock ram runs at.

So unless the bios lets you choose ram speed your often out of luck.

That said faster RAM does almost nothing for you and you can expect to pay a huge premium for "the ultra top end" so unless your intending to get it for more épeen rather than more performance you can just forget about it for now until later in life when its standardized.

 

The Macbook Pro comes with 1333 CAS 9 RAM, so 1600 CAS 9 does have an impact in benchmarks. Since I'm doing professional audio which can be both RAM and CPU intensive at the same time it also should help a bit.

The difference between 1333 CAS 7 and 1600 CAS 9 should be minute, as should be the difference between 1600 CAS 9 and 1866 CAS 11.

1000 / 667 * 7 = 10,5 ns (1333, CAS 7)
1000 / 667 * 9 = 13,5 ns (1333, CAS 9, this is the slower factory RAM)
1000 / 800 * 9 = 11,25 ns (1600, CAS 9, this one seems to work for everyone)
1000 / 933 * 11 = 11,8 ns (1866, CAS 11)

What specs does the new RAM come with?

 

From the review:

So this means that you can use the 21.33 multiplier correct? And the 2630QM that only support 1333MHz RAM, people got this CPU working with 1866MHz RAM by using some sort of XMP profile and got this RAM running there without it downclocking to 1333MHz. Haven`t heard anything about it being unstable though. But who knows, it may be the case.

@T1mur: I don`t know what you mean about specs, but the only available yet is: 2133Mhz [email protected] (from the PDF). This is CAS 9 RAM which is great btw

@Vicious: There are a lot to gain for people with IGP by using higher clocked RAM. The IGP is highly RAM bandwith dependable and reviews have shown that you get very nice increase in FPS in games with 1866 vs 1333.
In general you don`t get much performance boost by going 2133 over 1866 without IGP I guess. Reviews will show. But 2133 vs 1333 I can imagine being a nice upgrade for those who can afford it. And this is HyperX RAM, which is better than the stock RAM OEMs put in the notebooks.

 

If you get the Plug'n'Play kind, you don't need to do anything with XMP profiles or change anything in the BIOS. It runs at the speeds automatically.

 

But wasn`t the 1866 Kingston HyperX that as well?

 

Agreed! PnP memory is the best i say, no bios tweaking, any SB platform compatible) But the thing is that the tested modules are 2x2Gb with 9 CAS, i doubt there will be 2x4Gb ones with such tight timings... There're no 1333Mhz 7 CAS 2x4Gb sticks, right? so that's a minus...

 

Is CAS and CL the same?

Yes, CL = CAS Latency.

 

Still no news on the 2133 for notebooks after 8 months... anyone hear anything about dates?

 

Kingston has shown them again during the Cebit...

Most of the current BIOS won't run the RAM in 2133mhz even if a proper SPD table is present, so I guess they wait for broader Notebook support rather than having to deal with thousands of RMA cases.

 

Ram isn't for sale. The m18x my buddy made (that I'm buying to replace my desktop) he ended up using corsair vengeance 1866MHz Cas 10 but he got them to run at 1866MHz Cas 9. I think these are the best computer ram sticks you can buy at the moment, 1866MHz Cas 9. They are 4x4GB in the m18x he has so they atleast come in 4GB size.

I don't know of any 204 pin DDR3 SO-DIMM that can beat the corsair vengeance thats out for sale now and the kingston 2133MHz only come in 2GB size max and are not for sale. If there is something that beats 1866MHz Cas 9 than my apologies, maybe the 1866MHz 2x4GB Kingstown hyperx can run at cas 9 and tie it but nothing is beating it. Corsair Vengeance SO-DIMM's are the way to go as of now. It does have a i7-2960xm in it with all cores running at 3.8GHz so that might make a difference compared to lower chips as to what they handle
