16GB DDR3 1600 Now Available

[filmshoot]

Is this just sales talk ? Is the apple ram somehow better quality ? If I put after market ram in will it melt ? I am VERY skeptical myself but thought I'd ask people who may know more than me.

The apple sales staff has been notoriously going downhill, in terms of reasonableness. When I went into the apple store and called the last few times the sales people I spoke with have outright lied to me, or told me some very very false things. Some of which were said to get me to buy their product, in their section they were operating in, within the store.
Don't always believe what you hear, even if that person is wearing a nametag.

Yeah thats what it sounded like to me. My buddy and I went in looking at ipads and I brought up MBP's in a 'by the way' sense. He only mentioned this when I said something about putting an SSD into my old one and he cottoned on I might be willing to mod the thing myself

Though it makes sense. Getting things to the CPU and RAM faster is going to improve overall RAM and CPU performance. (Oh gosh. Flashing back to my Operations Management class.)

MaxBurn, if you want further proof:

Perfect, a program I am familiar with and have some trust in from the PC world. Would you please post the memory tab of CPU-Z? SPD is merely a reading on what the memory says it can do, not what it is doing.

All does look like it is working as intended though.

For referene this is mine from a late 2011 base model 15". Memory is this stuff which isn't really anything special:

I wonder if your Mac is really seeing and using the 1600Mhz.. I have an early 2011 15 inch as well and when I click on Memory it says:

Your Mac contains 2 memory slots, each of which accepts
a 1333 MHz DDR3 memory module.

STOP IT.

Seriously you guys are making my brain hurt. It's running at 1600MHz. You bought the wrong kind of RAM if it's not running at 1600MHz. That's all there is to it.

 

[Dekard]

Says 1333 is limit on my early2011 macbook 15 inch; not saying you arent; I doubt I'd really see any difference between that 1600 memory and the 1333 memory I currently have. Was just commenting on what my macbook says.

 

[shortcut3d]

I have the same MBP, sans the SSD and the Vengeance RAM. Got the 16GB Value ram and here are my results:

Those extra 500 points are probably from the SSD, even though the RAM test is higher on yours.

The SSD does not impact Geekbench scores especially if you have 8GB or more of RAM. With 16GB there is no way Geekbench scores are impacted by the primary drive. In fact, Geekbench should not be impacted by the amount of RAM if the system has "enough".

 

[philipma1957]

I think you are fooling yourself if you thing the memory will run at anything but the stock 1333MHz spec that apple makes the motherboards for. Waste of money for anything faster as the motherboard won't use it.

totally incorrect kingston hyperx 1600 and 1866 plug n play both run faster. MY BAD I DID NOT READ WHOLE THREAD SORRY

I was thinking the same thing. Can anyone confirm what 1600 memory says in the memory tab in cpu-z?

 

[Nightkrawler]

2 x 8GB 1600MHz Corsair Vengeance (CMSX16GX3M2A1600C10)

2 x 4GB 1600MHz Kingston HyperX KHX1600C9S3P1K2/8G

Interesting to see that they are using a slightly higher voltage.

1.5v is the spec. Mine is only lower because I got the low voltage stuff and was the same price as the others. Runs slightly cooler.

 

[mfuchs88]

Even if your computer does run it at 1600mhz, the performance difference will be pretty minimal. I would just get 16GB of 1333mhz because it's cheaper and for a 5% performance increase, it worth 50 dollars more. This is on sale for 99 bucks, and the reviews are excellent. http://trdd.us/pn

memory factors

There are 3 things to consider when comparing memory:
- frequency
- timings
- voltage

These factors kind of trade off against each other.

default mac ram: 1333Mhz, CAS 9, 1.35v
Vengeance: 1600Mhz, CAS 9, 1.5v
Vengeance: 1866Mhz, CAS 10, 1.5v
Hyper-X: 1600Mhz, CAS 9, 1.5v

So although might be gain slightly more performance from the 1600 ram, it will likely use more power and generate more heat.

There are some new low power modules:
Samsung low power: 1600Mhz, CAS 11, 1.35v

But because of the worse timings, these would likely make little difference.

 

[MaxBurn]

I don't know about you but the memory in my late 2011 was a regular old 1.5v.

Heres 1866mhz Hyper X

 

[NickZac]

Heres 1866mhz Hyper X

I am a little confused...that is on a Windows computer, isn't it? The 1866 will go in a MBP but it will only run at 1600, right? The SB CPUs in the MBP topped at 1600 MHz...or am I wrong?

It's on bootcamp and it runs at 1866mhz on OS X.

Hyper-X: 1600Mhz, CAS 9, 1.5v

One of the timing parameters is tRas.
Vengeance (2x4GB) has tRas=24 - a bit faster than Kingston tRas=27 !

Full timings for Vengeance (2x4GB) : 9-9-9-24
Full timings for Kingston : 9-9-9-27

Awesome! Thanks for letting us know

3 beeps after upgrade

I upgraded to the vengeance 8G 1600Mhz and experienced the MAC 3 beeps warning during a meeting yesterday. Quite embarrassing..

I did use the computer over easter without problem though.
Maybe just an overheating thing..

Lets see if it happens again..

 

[grahamnp]

What's the difference this vengeance brand and the value brand?

Vengeance is their performance line. You don't really need performance memory if you're going to run the memory at stock frequencies. On desktops the requirement is debatable for all but extreme users and on notebooks I would say it is a gimmick. Just my 2C.

 

[DeepIn2U]

There's plenty of 1600MHz sticks with CAS 9.

Also, tests have shown that the HD3000 doesn't benefit that significantly from faster RAM speeds. Not that that stops me.

Waiting on 16GB 1866MHz CAS 9 RAM myself, and then some daring posters to test it to make sure it's finally stable with CAS 9 timings.

Unfortunately not all brands - and not very many - CAS9 PC3-12800 (1600Mhz) 204-pin 16GB of RAM. For me regardless of the speed ... staying at 8GB is not worth the upgrade $$; I might as well go for the 16GB upgrade.

host ... thanks of the link ... decent price considering the G.Skill matches with CAS11 (vs Corsairs CAS10) with $5 more.

Forgive the slight tangent here.....

I'm in the market for a new 15" MBP.
Plan to dual boot with win7 to run GIS software STATA, winbugs, R etc.
Anyhow want to max out ram but don't want to pay apple prices.

Was in apple store and apple guy made big deal of telling me how Apple RAM is better and how his mate stuck crucial RAM in his machine and ran every program he had and the crucial ram melted.

Is this just sales talk ? Is the apple ram somehow better quality ? If I put after market ram in will it melt ? I am VERY skeptical myself but thought I'd ask people who may know more than me.

Also one other question. I notice the RAM speed you are talking about is faster than the factory fitted ram speed. If you put in faster RAM does the motherboard adjust to that speed automatically ? Or you have to do something ?

Don't worry, there's 0 truth to that if you get the correct RAM. I have never had a problem with Crucial. In fact, first thing I do with any new mac is dump their stock RAM and max out on Crucial RAM. Saves a ton of $

have anyone tried to test run application that uses high cpu load for more than 1 hour?

is there any problem like overheating, hardware reload, or application crash?

Cheers. I went ahead and got a 15" 2.5Ghz MBP with 4Gb on board. I then went ahead and bought 16Gb crucial RAM =)

Amazingly I actually made it page out for the first time yesterday - running BOINC on all CPU's, Firefox, Excel, and Stata under Win 7 in Parallels
