1333mhz 3rd party ram availability?

[xgman]

OWC and transintl should get soon but not yet. If anyone sees the 1333 version for the Mac Pro in stock anywhere (other than apple) could you post it here? I guess I'll order 4x4gb and then try to sell my 3x1GB 1333mhz stock ram for half price somewhere.

[rhuk]

I see crucial.com has mid 2010 12-core (ie DDR3 1333) sets available. Prices seem a little high, for example 16gb kit - 8gb x2 = $1099. but as of yet, no one else seems to have them available.

[shokunin]

newegg has 1333 registered ecc ddr3 modules in 2, 4, and even 8gb sticks. They are not specifically made or certified for the Mac Pro, but they may work. Looks like 8gb x 3 1333ecc is sold out at $899, it was available last night... hmmm I wonder why?

[xgman]

Looks like the usual places will have this up to order by tomorrow. I'll probably get 4x4 for the 3.33 6 core. Too bad that only the first 3 slots will be in triple channel mode. I guess it still will be better to fill the last slot rather then just 4x3 for 12gb. Just seems weird and backwards to me though.

[keewe]

i'll get 3x4GB for my 6 core. the last slot will be filled with one 8 GB module as soon as these modules are cheaper.

OCW sells 8gb modules for around $380 and 4x4 for $610, so around a $70 premium for an 8gb module.

Ordered 4x4 for $568 on transintl.com just now. Hopefully it's good certified ram. A bit less expensive than the OWC version. Sure a whole lot less than Apple charges. Do you think the stock 1 gb modules are worth anything to sell for cheap on ebay or whatever?

Very good news! Since transintl has no price difference between 1333 and 1066 MHz RAM, hopefully it will be the same for OWC. And with the rebate program OWC has, buying 16GB will end up being cheaper than transintl.

I mean for the 1333 sticks. Maybe they would accept them but I don't think they sell less than 2gb sticks of 1333 (when posted), so I'm not sure. In any case only $27 total. I'd almost rather send the single sticks to forum users so they can get to 4gb from 3 stock, and only charge shipping.

Well since they don't even have the 1333 sticks for sale, what makes you think they will already be buying 1333 sticks from people?

And for those with DP machines, $54 would be worth it.

[strausd]

OWC just put up 1333 MHz RAM for the Mac Pro. They only have 2GB sticks tho, no 4GB or 8GB yet.

I would just wait until they get their 1333 RAM up for sale first. They're probably trying to put everything together to publish online as we speak.

Lloyd Chambers is reporting (http://macperformanceguide.com/index.html) that in his discussions with OWC, it is unclear if the new Mac Pros will support 8GB modules:


"I discussed memory on the new Mac Pro today with OWC. From what I understand, it appears that 8GB modules might not work in the new 2010 4-core and 6-core Mac Pros. Since 4 X 4GB = 16GB, it appears likely that 16GB memory could be a hard limit for the new 2010 Mac Pro. This is not yet confirmed and won’t be until OWC gets the new Mac Pros in house (Apple site is stating “7-10 days”)."

The rep I spoke to earlier said later today or sometime tomorrow the product page will be up. Still not up yet, but I'll keep checking. Can't wait to get a new Mac Pro moved in.

OWC just put up 4GB modules. 16 GB (4X4) is $720 from them and $580 from transintl. The thing is I can get $54 back from OWC with the rebate program. So if transintl RAM of good quality? Is OWC RAM quality better and worth the extra price?

The thing I consistently hear about OWC is their testing is thorough. Where do you see the link for the new 2010 Mac Pro's on their site?

You seem to have all the hidden links today. Do you mind sharing where you got the $54 rebate from? Their current rebate page still doesn't seem to list 1333GHz RAM yet...

[reel2reel]

Sweet, thanks.

So now I'm confused. When I spoke to the OWC person, I asked whether or not the existing 1066MHz RAM (for the 2009 Mac Pro) would be compatible with the new 2.4GHz 8-core machines. He said no that it wasn't fast enough for the new bus speed.

But the Apple spec's clearly say the 2.4 GHz MP's are 1066MHz.

So I wonder which I need to purchase. I guess all will be clear when they get their product page up.

Edit: Well, when I configure a mid-2010 Mac Pro 2.4 GHz, it shows me early-2009 RAM, so I'm guessing the guy I spoke to was assuming all the new MP's were 1333MHz.

[strausd]

Not sure about that. But since the 1066 1GB modules are the same rebate price as the RAM from the 06 and 08 1GB modules, I doubt it will be any different.

You do not want registered DIMMs. They might work, but you'll take a performance hit. You want unbuffered instead. Prior to now, unbuffered ECC DIMMs at 1333MHz were hard to find, but hopefully that will change now that the Mac Pro is out.

Registered (buffered) DIMMs are used for servers that have many banks of RAM, to allow them to address multiple banks. Mac Pro only has 4 slots per CPU, so it doesn't need registered memory.

Ah nice! Thanks for posting.

I feel like shopping, but think I'll wait until they finish their testing and figure out whether or not the 2010's accept 8GB sticks. Although, they're selling 8GB combinations.

EDIT: sorry, what I meant to say is "wait to see if the new MP's have 16/32 GB limits" as reported here: http://macperformanceguide.com/index.html

Just finished a 14-hour shift, so I'm a little loopy.

Np. Thanks for the original heads up. I wouldn't have kept checking if I didn't know they'd be working on something for today :)

That's a good idea on waiting. I'm curious as to see if the SP machines can support 32GB. I might just wait a bit as well then.

Hopefully, it turns out to be untrue. The 3.33 GHz six-core is looking like a sweet-spot in the lineup (if you're not needing more cores) but it would suck if it had a cap of 16GB RAM.

Don't the Quad Cores use the same 1066Mhz RAM as the 2009 model? The price is jacked up a bit from the 2009 RAM page (the 4GB modules).

Just ordered 12GB of 1333 RAM (4GB x 3) from OWC for my 6-core Mac Pro. I figure I'll use the Westmere's tri-channel memory controller and wait to see if I can go to 8GB sticks next year for 24GB. Note OWC is only selling the 8GB sticks for the DP machines, so it's not clear yet if they can be used on the SP Mac Pro's.

I ordered 16 GB 1333 MHz 4 X 4 GB for my 12-core machine. After using it for a while, maybe a year or so, I'll upgrade to 24 GB with dual tri-channel :) I'll probably stop there and not go up to 32 GB.

Apologies if this is a stupid question....

Just about to order the hexacore - will be buying RAM in the UK so will probably need to use Crucial.

Can someone explain to me the benefits of having tri-channel memory? I assume that having 4x4GB is better than 3x3GB but lots of people seem to be opting for the latter...what's the benefit?

Also it seems if I did want to go for 8GB sticks (2 or 4 depending on whether real world tests show the hexacore can take 32GB) the only ones Crucial sells are registered, which per the above (very useful) post is not what I want - is that the same for OWC and other vendors in the US?

Thanks!

It's not really having tri-channel memory, but rather using 3 memory slots. Opting for 3x4GB is beneficial because the processor only has 3 memory channels.

When putting 4x4GB, the processor doesn't operate in triple-channel mode.

When operating in triple-channel mode, memory latency is reduced due to interleaving, meaning that each module is accessed sequentially. Data is spread amongst the modules in an alternating pattern.

I noticed this and wondered why as well. (at OWC) Could we not just order from the cheaper page, or is there really a difference in the RAM?

[johnnymg]

Would there be any technical disadvantage in using 1333 RAM in a single quad 2010 MP?

I just spoke to OWC again and they're obviously still getting things figured out. Apple hasn't even released the tech manuals to them yet. The person I spoke to confirmed the only price difference is in the 4GB modules, but he's not sure why at the moment.

I'm going to wait until the end of the week and check back again. I'm most concerned about the alleged RAM cap.

Why on earth are two of these RAM modules http://eshop.macsales.com/item/Other%20World%20Computing/8566D3MPE4GB/

I ordered mine form transintl. It ends up being $150 less that OWC for 16GB.

Another thing people might want to be aware of is that when filling all the memory slots on the systems using 1333MHz it is likely going to run at 1066MHz unless Apple have deviated away from the standard Intel spec (something they don't tend to do), thus there is no reason to not use 1066MHz memory in such a case. If you already have it or can get it cheaper for example.

Where are you getting this? Doesn't make any sense. Maybe in the 4th slot, but I think that just doesn't run in the triple channel setup like the first three. The first 3 surely are running at the quoted speed if you are on a 1333 platform.

This is how the memory system works on dual processor systems. Memory all runs at the speed of the slowest DIMM. 1 DIMM per channel = 1333MHz max, 2 = 1066MHz, 3 = 800MHz. Some board manufacturers (Tyan, ASUS and Sun) made it so you could overclock the memory to make it all run at 1333MHz, but it isn't part of the standard spec so I wouldn't expect it from Apple.

edit: Nevermind. That is how it works, but there is an exception with 5600 series Xeons and 1333MHz UDIMMs specifically, where it should all run at 1333MHz.

OWC's website doesn't list any 8GB modules for the 6 Core, but they do list it for the 12 Core (both are 1333). This doesn't make sense to me. Couldn't the 8GB stick from the 12-Core work in the 6-Core? They are both identical?

It may, but no one has tried it yet. It is not "officially" supported.

Just out of curiosity, why would anyone need over 16Gb of RAM anyway?

Some apps eat up a ton of RAM (such as Adobe After Effects). I'm guessing the more RAM the better if you're running a lot of app's at once. The more cores you have, the more RAM you need (for example, rendering with Virtual Clusters in Compressor).

The biggest reason of all, I'd say, is that future app's are going to require more and more memory.

I'm no expert, just telling you what I know from my own experience. A graphics guy I know had 16GB of RAM in his Mac Pro two years ago. I imagine is next bump will be to 32.

We use FCP all day on Macs, usually with no more than 8Gb of ram in each computer. Our tech's feel any more is overkill.

[shokunin]

While I know they are cautious about the 8GB Dimm compatibility, I don't see much of change from the 2009 version. From what I remember of taking apart a 2009 quad Mac Pro is that the chip was a 3xxx series Xeon and not 5xxx Xeon. The previous 3xxx Xeons still had a maximum of 24gb of RAM yet, OWC was able to get up to 32gb installed in the 2009 quad Mac Pro's.

So do I, but I don't know if I agree that more than 8GB is overkill. I'd have to see for myself. When I've got Color and FCP both running with 1000 shots in each timeline, I start to feel a bit of lag. Maybe 12GB would help, maybe not.

But 16GB for After Effects is probably bare minimum if you're doing a lot of sophisticated work.

But if the extra ram really doesn't do much, it's money in the toilet.
