Mixing RAM from different manufacturer's?

Hi
i currently have 2.5 gig of ram that was installed by apple, and i am looking to add matched pair of 1 GB to give me 2 more gig of ram, and 4.5 total
can i mix my standard ram with samsung ram? i dont want to buy and have it not work, also there is same ram on the site with slightly different specs for less, a, i better off going with that?
thanks in advance!

Hi, and a Warm Welcome to the Power Mac G5 Forum!
Well - the G5 RAM specs are here
http://docs.info.apple.com/article.html?artnum=86414
Some of the Apple Original G5 RAM was Samsung, apparently.
You will not go far wrong purchasing RAM from OWC with their "Lifetime Advance Replacement Warranty"...
Personally I have never had a problem with Crucial
http://crucial.com/store/mpartspecs.aspx?mtbpoid=1D1DFB01A5CA7304
who have a similar guarantee. And the parent company of Crucial - Micron - were also suppliers of Apple Original G5 RAM, apparently. Good Luck.

Mixing Ram with different CAS latencies in K7n2 Delta-L?

I have been using 512mb Kingston Value Ram in my computer, pc3200, with CAS latency of 3.0. I just purchased some Corsair value select 512mb ram pc3200 with CAS latency of 2.5. I know you are not supposed to mix ram with different speeds (like 400 vs. 333) but does it matter if the CAS latencies are different?
I'm running an AMD XP 1800+, K7n2 delta-L, nforce2 motherboard from MSI. Someone at a computer shop told me they tried mixing Kingston 3.0 CAS with Corsair 2.5 CAS, and said his computer wouldn't even post. So I'm wondering if this is an isolated problem, or you will always run into this problem if you mix ram with different CAS latencies.
If anyone has experience with this issue, please share with the board. Thanks!

The age old question, will the components I bought be compatible ? There are those that have bought identical matching memory that didn't work. In my case, I had an ECS K7S5A that used PC2100 Crucial memory, the sticks neither matched (at one time they did, but one stick died and they sent me the closest thing they had.). Neither of these Crucial sticks was identified by a configurator as being compatible with the K7N2 Delta L that I decided to buy. In the end, not only did both sticks work, but I put them in as single channel mode (ram slots 1 & 2), but later changed the configuration to dual channel mode (ram slots 1 & 3, even 2 & 3). It worked flawlessly in all three configurations. Sorry for the long answer, but in essence, there are no guarantees and your worries will drive you crazy. When memory is mixed, you reduce the likelihood of compatibility, even when you go beyond the recommended products that were specifically identified.
That guy at the computer shop, did he ever indicate or isolate the true reason why the memory wouldn't work ? Maybe, maybe not. I would think with a disparity in memory, the bios is the key to setting the settings for the worst stick of the bunch. Then again, the products you get might overclock to what the better sticks run at. My assumption is that mixed sticks, the bios retards settings to this in "auto" mode. When you force it manually, it may work or it may fail. One thing you oughta know, each and every stick has the manufacturers id encoded onto them at the very least, just like the firmware on other items indicates a manufacturer code and other data that allows these things to be compatible. So know you face that battle going in with any of them. If the bios programming doesn't allow it to work, from that perspective, there'll be problems.

845PE Max2 RAID with 2 80 GB Harddisk from different Manufacturer

sorry for my bad english first
i have a 845PE Max2 and i want to create a RAID 1 System with my 2 Harddisks. I have a Western Digital 80 GB (7200, 8MB Cache, UDMA/100) and a Seagate 80 GB (7200, 8MB Cache, SATA/150).
can i create a RAID with these 2 harddisks or do they have to be absolut identical?

I have two drives from different manufactures in a raid configuration and it works ok as long as they are the same size.
However it is not a RAID 1 configuration it is a RAID 0.
RAID 0 - combines 2 drives as 1. in my case 2 x 30Gb drives became 1 x 58 Gb drive.
RAID 1 - needs 4 drives the same it would combine 2 drives as above with the other 2 doing the same. The second pair of drives would hold a copy of the first pair so if there was any loss of drive integrity (i.e. failure) the second pair may be used to correct the problem.
As far as I know that is the way it works but please do check around the net for the definitions of RAID configurations
try
http://www.iomega.com/support/documents/11242.html
for definition of RAID 0 and RAID 1.

Mixing pages from different themes

Is it possible to mix theme pages within a single project?
No single theme works for my current project. The problem is not so much the picture layouts but the text. I need one of the Title Page formats from the Folio theme, plus some of the Text Page formats from the Simple Border theme.
Much appreciated

No. You can only have one theme. However, you can create custom pages like described in this tutorial: Old Toad's Tutorial #19 - Creating a Custom Page, with the Theme's Background for an iPhoto Book. This way you can have a page from each theme in one book if you'd like.

Mixing audio from different clips: levels dropping automatically?

Hi,
I have a few clips containing audio. Then add 1 song to the timeline too, and I want to hear audio from both the song and the clips.
When I mute the audio of the clips, I hear the song at a certain volume. See video+song here: music only - YouTube
But when I also enable the clips audio, the volume of the song gets a lot lower automatically. See video + song + clip audio here: music mixed - YouTube
I realise that adding the audio on top of each other will result in peaks that are too high, but I don't really care if these peaks get clipped. Most parts of the clip audio have a fairly low volume, but even on those parts the volume of the song stays very very low.
When I decrease the audio levels of the song and the clips to keep the master levels from going into the red zones, the same thing happens. Only the overall audio mix has a lower volume (but still the song volume goes down when played together with the clip audio).
Is there any reason for this to happen? Does this depend on some settings, can it be my audio hardware that causes this?
Thanks for any help.
ps: I come from editing in vegas, and never experienced the same problem there

I have my waveforms back! Thank you SO MUCH! I looked everywhere and just couldn't find a setting for this.
As for the sync, I guess that's OK - it's no worse than what I had before (and with the waveforms back, less of an issue to do manually). Would be nice if they'd add the ability to offset the audio track in the Modify Clip screen at some point (and it would open up the multi-cam sync feature to more users), but I can cope without for now.
Thanks again for your help.

Mixing RAM Manufacturers?

My apologies if this has been asked before; I searched the forum but couldn't find anything that answered my question properly. So-called 3rd party Memory is new territory for me.
I'm looking to upgrade the RAM in my iMac at home; it's a late 2006 20" 2.16 C2D.
I was wondering if anybody could tell me if mixing RAM by different manufactures will cause any adverse effects or instability? Of course taking into account that the memory is in perfect working order. Also, what manufacturers available in the U.K are most reputable with regards to stability and useful working life? I work in music production so good RAM and stability is a must.
Currently I am considering a single Crucial 2GB module, mainly because they seem to have a good reputation around the forum and it's very reasonable priced.
http://www.crucial.com/uk/store/mpartspecs.aspx?mtbpoid=5A5FD16EA5CA7304
I'm also considering buying a further 1GB module (possibly Kingston) soon after should 2.5GB in the computer not be enough.
Lastly; would there be any benefit to buying a second 2GB module (instead of the 1GB)? I know each slot can accept a 2GB stick, but I keep getting conflicting info as to whether 4GB can actually be addressed in the late 2006 white 20" iMac (despite the spec being 3 gigs).
Cheers.

£32 for one 2GB module! Now I feel seen-off. At the end of November I decided to buy just a 1GB SODIMM as that was £17 versus the £57 they wanted for a 2GB modules. Today I could have bought a full 4GB for £64. Nevermind, I don't actually need that much RAM.
At those prices I'd buy 2GB now and then 2GB later. You'll get to use 3.3GB as den.thed says and because you'll have two modules from the same OEM you'll be sure they will pair up and you'll get the benefit of matched RAM.
I'm also going to re-iterate my usual gripe about Kingston: Kingston Value RAM (slightly more than Crucial) doesn't work in Macs (Kingston themselves told me that). It caused Kernel Panics in my old iMac. If you use Kingston System Specific RAM (about twice the cost of Crucial) it'll work just as well as the Crucial.

HT3918 Mixing RAM modules in a late 2009 iMac

I have a late 2009 27" iMac that came with only 2 Gig of RAM. I recently ordered 16 Gig of RAM (4 modules), but they only shipped me 8 Gig (2 modules). I installed the 8 Gig (still leaving me with 2 empty slots), can I also reinstall the two 1 Gig modules that I removed for a total of 10 Gig?
Also, if I order an additional 8 Gig from another company will it cause problems to mix products from different companies?

Welcome to the Apple Support Communities
The Late 2009 iMac came with 4 GB on all the models, so maybe you have an Early 2009 iMac.
Apart from that, if you have a Late 2009, you can use 16 GB of memory, so you can install two 4 GB modules and two 1 GB modules, for a total amount of 10 GB, without any problem. If you have an Early 2009 iMac, 8 GB of memory are the maximum.
To buy memory, I only recommend you OWC and Crucial, that provides compatible memory with Macs. Other brands may work, but with OWC and Crucial you can be sure that memory will work with your computer > http://www.macsales.com

Install RAM in pairs but from two different manufactures?

I was wondering if anyone could tell me if there may be any issues with installing RAM in pairs in my PMG5 from two different manufactures. Any feedback is greatly appreciated. Thanks!

Sometimes there has been, because not all RAM from even the same vendor is 100% identical from batch to batch. It should or might, but there are variations in timing, voltage which have in the past caused problems, mostly when a new revision or model comes out though.
When in doubt, check with reputable sites like
http://www.crucial.com/mac/ etc. and compare.

MIXING ORIGINAL APPLE MEMORY WITH MEMORY FROM ANOTHER MANUFACTURER

Hi everyone,
I'm about to hop on the mac train and buy a macbook 2.16GHz( the recent previous black model)
It's coming with 1GB of memory and I wanted to buy 2GB to add to it. I found a good deal for a OWC 2GB DDR2 PC2-5300 667MHz DIMM(it's one stick of 2GB).
Is it compatible to mix different memory makes and if so, is it also optimal? Would the optimizing power be the same if I used all the memory from one manufacturer or it makes no difference? Thanks.

You do get a slight advantage by using 2 of the same capacity RAM modules. (i.e. 2x1GB chips or 2x2GB chips). In practice, however, this performance gain really isn't noticeable. You have to run a memory benchmark test to see the difference.
I remember there was this supposed IT guy who claimed that different brands of memory "fight it out". Some of the answers were absolutely hilarious. Seriously, there's nothing that consistent about a single brand of memory. There are always variations, but I wouldn't worry about a thing provided the memory actually meets its published specs. You get variation quality with memory modules that aren't fully-branded by one of the major memory IC manufacturers, but there are some reputable brands out there (OCZ, PNY, Patriot, etc).
I have an iBook G4 1.42. For two+ years I've been running the permanent Samsung memory with a 1 GB Micron PC2700 module. I've never encountered anything that suggests that there is a problem with it.
I've also read the Intel specs on what the chipset does with memory sized identically. Apparently it can do that very same thing (memory interleaving) even if the sizes aren't matched. However - it'll only do that for up to the size of the smaller module, and the remainder of the larger module isn't interleaved.

I have a Apple MacBook Pro "Core i7" 2.8 13" Late 2011. i want to upgrade its RAM from 4GB to 16GB. But OWC sells two kinds of RAM, the DDR3 and the DDR3L.What is the different and which one would work better for my mac. Thanks!!!

I don't see any DDR3L on the page for the RAM that would fit your model -> http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_133 3MHz_SDRAM.
But the answer is that it doesn't really matter - just make certain to get 1333MHz.
Good luck,

Mixing ram sizes

Hello,
I recently purchased a macbook pro i7 late 2011 edition. It currently has 4GB of ram(2x2GB). I am wondering if it is possible to purchase a single 8GB(1x8GB) stick of ram and trade out one of the old 2GB sticks in order to have a total of 10GB of ram. I am aware 16GB ram kits are available but they are currently too expensive for me so atleast this way I could purchase one stick of 8GB for now and then purchase another down the road.
8GB of ram is not enough for me. So my question is if whether or not I can mix ram sticks. Please only respond if you know for a fact and why, I don't appreciate people making guesses.
Thank you!

No one can answer your question with certainty. Some people mix different RAM brands and sizes and even speeds, and don't have any trouble. Others try it and have nothing BUT trouble. No two Macs or Mac users are alike in all respects, so there's no knowing why it works for one and not for another. It's a safer bet to use exactly matched pairs, but you might be fine with whatever mismatched modules you choose. If you buy from a vendor who offers a lifetime warranty, you'll probably be able to return anything that doesn't work out for you. But you can't eliminate the chance of getting bad RAM no matter what you buy, and you can't be sure that even a good module will behave perfectly when paired with a module that you have now.
There are some vendors who offer RAM modules in pairs from one manufacturer but in unmatched sizes, and warrant them to work properly together. You may want to consider buying a 4GB and an 8GB module from such a vendor, adding a small amount in cost but giving you 12GB and a solid warranty. Here's one dependable source:
http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_133 3MHz_SDRAM
Note that the extra 4GB only costs $15 more than a single 8GB module.

Dynamic link confusing two separate AE compositions in PPro from different projects

I am using CS5 Master Collection for Windows 7 (64 bit) on an HP Pro desktop (Intel core 2 duo, 6Gb RAM). The tower has two hard drives installed (no RAID). CS5 is installed on the original C drive along with the OS, but the working files, footage etc are all on the larger, secondary F drive.
I am working on a DVD project consisting of several seperate PPro projects. Each project has been colour corrected in AE using dynamic linking. Recently two of my projects suddenly became mixed up, by which I mean the video (not the audio) from one AE composition in one project has taken the place of another in another project. The clip remains the same length, but the link apears to be referencing the wrong clip during playback. Interestingly, there are two clips on the track above the affected clip that fade out and in at either end, during the dissolves between clips, the correct footage plays. It is only when the clip plays by itself that the problem occurs. The next clip also has the same error, though the problem only occurs for half the clip and then suddenly corrects itself. Just to be clear, All clips have been rendered, there are no more than two video tracks on the sequence, and I have tried replacing the composition from the asset menu (in which the clip plays back correctly), but the problem remains in the sequence.
I hope that descrition is clear enough. My guess is some kind of file path error in the dynamic link, perhaps due to the separate hard drive. But I really wouldn't know. I'm very pressed for time right now and I'd prefer not to go against workflow and re-edit a new composition in AE, I would also like to understand what is going on in case it happens again.
Any help with ths problem would be appreciated,
J

Thanks Colin, I tried what you suggested with both the AE Project that it should be referencing and the AE project it is erroneously referencing but both failed to fix the issue. Its as if a hidden clip were laid over the top of the one I want to play. Frustrating.

It's not the comps that are the problem; it's the project file names themselves. You can have all the comps in a project named the same thing, and it'll be fine, but naming projects incrementally is an issue. After Effects includes a versioning function (Save and Increment) that will create a new AE project file with a serial number, e.g. AE Project 01, AE Project 02, etc. This is all well and good if you're just working in After Effects, but Dynamic Link gets confused and will usually start looking at the later project file for comps. That will just create a big mess, as you've found. Changing the names of the project files won't help things relink automatically properly, but it can help you fix things. Make all your DL AE comps offline in your Pr projects, and name your AE projects in a manner that is not serial (give them more random names). Select your offline AE comps, and right-click > Link Media, and point to the new AE project. Things should link up correctly then--but if they don't, you'll just have to remove all the AE comps from your Pr project, reimport the comps from the newly-named AE project, and replace them. It's a pain but it'll probably just keep getting worse if you don't.

Final cut pro make Mac pro kernel panic with RAM from other manufacturers

hi all
if i installed RAM For mac Pro from 667MHz DDR2 fully buffered ECC RAM from other manufacturers
final cut pro (just final cut)
make the machine kernel panic messege
all programs working good (like adobe and other compositing program) but final cut freez the machine and kernel panic
the standard RAMs good

Ahmed:
You can try visiting/searching the Expanding your Power Mac G5 forum. You'll find A LOT of help about RAM issues.
Any RAM brand must work but you maust be sure it follows the MAc specs. Some brand sites have good product locator by computer manufacturer/model (i.e. Kingston and Crucial). In fact there is no Apple branded RAM, they use a lot of different ones.
Inside FCP settings you'll find how to manage the memory that the program use, but that settings depends on the total quantity of memory you have installed, and you didn't post that information.

Mixing RAM Modules (1gig + 2gig = 3gig)

Hello,
I am about to buy a Mac Mini and I am on a tight budget. The one thing I want to do for sure is upgrade the memory, but I'm in a quandary of sorts given my budget. The retailer where I want to buy the Mini from only sells the appropriate RAM for the Mini in 2gig modules. So here's my question: I know it is possible to mix the stock 1gig stick with a 2gig stick to get 3 gig of RAM total, but will it be worth it to me? I realize that the best configuration would be to slap in 2 2gig modules in and just be done with it, but with 3gig, would I be appreciatively shooting myself in the foot and killing the machine's performance, or wouldn't I notice? I need to have the memory installed at purchase because I am physically handicapped and adding the memory myself is out of the question. And after researching how to replace memory on the Mini, I wouldn't have the courage to ask anybody I know to attempt to do it after buying it. Is mixing RAM modules a good idea?
Thanks in advance.
Malcolm

Nope, I am not confused, There does have generation between Mac mini model. Maybe not official, but we all know. Check About This Mac ---> More Info ---> Model Identifier : Macmini2,1 (That means, 2nd generation)
Macmini 3,x (means 3rd generation I supposed)
And the 3rd generation doesn't support Dual Channel, referred to Crucial.com

Mixing ram

recently got my new imac, and since i use it mostly with logic, and i respect most opinions here, i'll ask this here.
i am thinking about buying a 512 for my imac from someone on craigslist . he pulled it from a MACBOOK. i know both are sodimm and both are pc-5300 - his is hynix, i don't know what mine is. for $75 i could bump my ram by 100% which sounds great, but i've heard some people have reservations about mixing ram. thoughts?
ps. i know matched ram gives a slight performance boost, but i just need more breathing room, and $75 seems like the right price.

yeah kid i'm with jord on this
i just had a big thing with RAMS not long ago leading me to deleting everything on my harddrive and also not being able to install DVD and app been crashing alot
but after I removed them rams things runs smooth
so RAMS plays a big roll in your system, so get the best and make sure they match and work as well
