Buying RAM for Quicksilver

I am thinking about buying this RAM. there are two specs that bother me about it.
1: it's only 2.5 volts and Apple says a Quicksilver requires 3.3 volts
2: it says it is a dual 512 MB card. I read in an Apple article that no memory gains are seen when two DIMMS of the same size are installed. My J21 slot has 512 MB in it. Does a dual 512 MB in J22 improve memory or no?

Hello,
I've just added older Infineon 512MB SDRAM into my Quicksilver and it works and this RAM isn't offered at ANY apple shop. Try to check developer note about your model (search on developer.apple.com for "PowerMac G4"), there is a section about RAM requirements in great detail. Usually if you try google: "type of your ram", you'll find similar specs on the site of manufacturer. If they match, no problem. If they don't match - 90% it won't work. Care about number of units (has to be 16, 8 on each side of RAM for 512MB pieces)
It's just my opinion, but I think that there is no need to pay extra money just for RAM which is recomended by OWC or any other apple shop. I think most reliable source of information is detailed specification provided by manufacturers.
I guess "1GB RAM kit" is just "psychological trick" to sell better - eg. it's generally known, that 1GB DDR dualchannel kit consisting of 2x512MB pieces can be faster than single 1GB piece in some computers. Nothing to do with SDRAM, which you need.

Suggestion for buying RAM for my laptop T420

Looking for suggestion buying 8GB RAM for my latptop T420
I recently bought a used T420 which came with a 2GB from an online site. Machine woks all great with the current config. I would like to install 8GB RAM to make it faster as I have been installing lot of softwares on it.
Bit confused what to look for as products have keywords like DDR3 / PCI slots / 1333MHz, 1.5V .. not sure what to get.. can someone suggest what should I be getting ? If possible can you share a link ..
Thanks.

This is from Toms Hardware;
"2x4GB allows to run in dual channel, but no, not 2 times faster, a single stick operates as a 64bit device in dual channel the two sticks operate together as a 128bit device which in reality provides for up to an appr 15% gain in performance vs single channel - the lower the latency at a given freq the better performance, however have to take into account the freq also a 1333/CL7 set can't touch a 2133/9 set in sheer performance + the higher the freq the higher the bandwidth so the more data can be dealt with in a single clock cycle"
However, the best choice for you now, since you're upgrading your RAM is to go Full Monty on it and get 2x 8GB paired, because if you only decide on getting one, then you might have a hard time finding a matching 2nd module later. But there would not be a significant performance hit you'd take from getting a different module, not anything you'd notice at least. It's just good practice to get them paired. My 2 cents.

Buying RAM for MBP

I just bought a MBP with 2GB preinstalled, expecting to upgrade to 4GB through a 3rd party in order to save money. I was going to go with newegg.com's RAM, but now after thinking about it I'm starting to have cold feet, and there are a few things I need to straighten out before making the purchase.
First of all, is there any difference between the apple 2x2GB sticks for $180 and a 3rd party's for $80-$140? I'm a bit nervous about "getting what I paid for". It seems like the only difference would be the warranty that apple has, and even the sales guy at my local apple store said he would reccommend buying RAM through a 3rd party as long as I'm comfortable with installing it.
Second, on newegg.com the RAM products are titled "Company Name" 2x2GB RAM for apple notebook model "Then a string of letters and numbers, presumably the model number". But when I checked the model numbers of MBPs, none of them matched the model numbers that the RAM was for, and to make matters even more complicated, there are customer reviews on the site saying that they bought the RAM for their MBP and it worked great.
Third, if I do decide to go with a third party, is there any difference in quality between the $77 Patriot RAM and the $140 Corsair RAM as long as they're all DDR2 667?

Your model requires PC2-5300 DDR2 667 MHz SDRAM as set forth in the technical specifications in your computer's User Guide. Any brand RAM with those specifications will work. You will often find retailers offering two variations: an "economy" price for product that carries at best a one year warranty (sometimes it's unbranded or retailer branded); and the regular branded product that carries a Lifetime Warranty. The latter is higher priced but is what you should purchase.
Prices will vary so do some shopping. As long as the product comes with the Lifetime Warranty and the reseller has reasonable return policies in the event you get a defective product, you need not be overly concerned about who made the RAM or the retailer from whom your purchased it.
Some reasonable sources are:

Where should i buy RAM for my iMac??

Where or what website should i purchase RAM from.
i am looking to upgrade my Imac 27" (fall 2013)
i like to go from 8GB to 16GB or possibly 32GB
will be working on FCPX. lots of video editing.
someone suggested www.macsales.com
and suggested using OWC upgrades.
anyone have any advice ???
thanks

My advice. so mileage may vary.
OS X 10.8 Mountain Lion, by itself, can eat up 4 GBs of RAM.
If you install only 16 GBs of RAM, this really leaves only 12 GBs of a usable RAM for other applications.
You do not, necessarily, have to install the complete 32 GB of RAM.
You could install 20-24 GBs of RAM and will, probably, still be in good shape, in terms of RAM.
What is really needed for video editing is a fast CPU and powerful GPU ( at least 1 GB VRAM) and lots of hard drive space.
So, I would recommend investing in two fast USB 3.0 or Thunderbolt external hard drives.
One drive (1 or 2 TB storage size) for a working drive for data and editing of Final Cut files and one other drive ( 2 TB or larger data storage space) to use as a complete computer data backup drive solution.

Hi, X, et al,
I too have been using these exact same Corsair DIMMs with no problems since April. The "however" part is that I would get 1600mhz CL 9 DIMMs instead at this juncture. They don't cost much more, and if you want to upgrade your existing 1333mhz RAM at some point you can, without throwing away all four DIMMs. Yes, you can mix 1600 and 1333 - they will be clocked at 1333. Just make sure to get CL 9 and not CL 11. For example:
1600 mhz CL 9 $50 8GB
might work out for you. I do prefer buying from Amazon over Newegg though. Less return hassles.
Anything higher than 1600mhz is a waste - it's the fastest clock rate your chip set can handle.
Best, ZZ

Buying Ram for Qosmio G45-AV680

Hello everyone,
I have a Qosmio G45-AV680 with Win 7 (32bits).
One of my ram chips died so I'm left with just 1GB.
Can I buy a 2GB chip so that I end up with 3GB total?
Or should I use them only in pairs? (I know that there used to be an issue with older pcs)
I read that some Windows only recognize up to 3GB, can someone confirm me that Win 7 accepts 4GB?
Thanks in advance.

HERE are your machine's specs. You can handle up to 4 GB in any configuration you want. For example, you could add either a 1,2 or 3 GB module; however, I notice on the spec sheet that Toshiba only offers 1 or 2 GB modules. From what I've learned on this Forum, Toshiba laptops are finicky when adding new memory so best to stick with either Toshiba or Kingston. Good Luck!

I get three beeps when I start my 2008 15" MBP. I'm thinking RAM problem. Is it possible to buy RAM for my (ahem) vintage model?

I Get three beeps when I start my MBP. It's an old model 2008 15". I think I need to buy new RAM. Is RAM available for these older models?

RAM is available from OWC and Crucial, the best sources of Mac compatible RAM.
Ciao.
Take out the RAM modules and clean the contacts. Reinstall them making certain that they are well seated.
If the tones come on again, test by installing each module in each bay to determine if the module or the bay is faulty.

I fear I may need to sell off some pre bought RAM.
What are the main considerations for buying RAM for a 2011?

Many of the recommendations including those of Harm are items you should consider. Overall the important points to keep in mind are noted below.
The IMC memory controller is only validated at 1333 and 1600. While our UEFI and board have been developed to allow for support of higher dividers this supports varies on the quality of the IMC. Most IMCS will not have issues running up to 1866 in full population. Keep in mind though that the higher the density and the higher the frequency the hard it becomes for the memory controller to stability. Currently we have for normal users validated up to 2400 XMP but this requires an outstanding IMC ( with sheer luck in that a CPU will offer running this frequency and density ). Higher frequencies are of course supported whether it be overclocking a module or even using higher rated kits ( 2600+ )
If you are pursuing high density configurations whether it be 32GB or even 64GB to ensure the best level of compatibility and stability i would advise you run 1600. 1866 as well should be ok. In regards to vendors GSKill has outstanding SPD and XMP programming and we have an extremely close relationship with them during the development and validation of their modules ( this is why you will see our boards continually under there compatibility lists for kits ) Although keep in mind that for all memory vendors much of the higher frequency memory kits are validated on high performance IMCs on select CPUs. In this respect while that module has been ensured to run at that speed it is not a guarantee to run on your CPU ( unless the frequency is conservative and applicable to most IMCs )
Keep in mind also that not all memory manufacturers are using correctly defined XMP tables (meaning they can potentially make adjustment to voltages they should not be adjusting). Technically under the XMP 1.3 specification vendors are only allowed to define timings and frequency all MRC timings and voltages must be auto defined by the board ( excluding the primary DRAM voltage ). This is important as XMP in itself is actually defined to work on the worst motherboards this actually is not always ideal as it may have to work on vendor’s motherboards who have poor bios/uefis or lower quality trace layout which is key for optimal memory performance and compatibility. All in all XMP from a quality vendor will work on our boards but just keep in mind XMP may not always be "guaranteed or even the best settings for the modules".
Great vendors to consider for memory on X79.
GSKill, Corsair, Kingston, Patriot, Mushkin, Crucial,
In regards to compatibility we have currently validated with all active kits on the market for 32GB and 64GB. As of now we have no current compatibility or bit initialization issues ( can occur when vendors incorrectly code SPD or XMP information ).
Following up on your question in reference to QVL's these are outlined at the initial launch and generally completed 2weeks to a month prior to the launch as such you will find many newer kits not present. Additionally in transition periods of density increases ( like the commonness of 4GB or even now 8GB dimms affects considerations as these modules and even frequencies were not available at the time of the launch ).
Overall though we do compatibility and interoperability tests continually to ensure the best support possible. With that in mind there are factors that can influence initialization of memory.
Installation issues
1. Damaging of pins during installation ( even 1 pin slightly pin or damage can impact memory initialization )
2. Too much pressure from heatsink assembly can uneven pressure contact with the pin / pad ( socket to CPU )
3. Mixed memory revisions ( this can occur even with the same model memory kits ) Memory vendors change ICs over time as such memory while it should work at lower frequencies and more relaxed timings can have compatibility issues in higher densities due to sensitivities of the IMC. If possible also try to buy matched sets and ensure the revision number is the same across all modules.
4. Memory controller voltage this can be modified ( increased at times to help stabilize higher frequencies and higher densities ) this is more common for high speed kits 1866 and greater
Hope this helps!

Cheapest place to buy RAM?

I just got my new MacBook. I didn't want to spend 150 for apple to take my computer up to 2 gigs. Does anyone know where (online) is the cheapest place to buy RAM for a MacBook? I'm looking to buy two 1 gig stick thing-a-ma-bobs. I don't know what the technical terms is for them.

i have looked online for ram and while those sites do have good prices, you should check out frys.com. here is a link to 2 gigs of patriot ram for 50 bucks.

frys has been having super deals. if you look around, you can get 4 gigs for 109.99 from them too. super deal.

Ram for a Quicksilver 867mhz

hi folks,
i'm buying second hand ram for my quicksilver. i know it needs pc133 sdram. this guy selling me this ''Samsung 512 MB PC2100 DDR RAM (M368L6423DTL-CB0' says it compatible. I have tried googling but am limited in my undestanding.... is it compatible? Also a second question is this also compatoble Seagate 3.5" 160Gb IDE HDD a and will i be able to access the 160 gig if i install leopard? i read that this model can acccess 12O IN TIGER? thanks in advance!!!!

Hi-
The Quicksilver uses PC133 RAM.
PC2100 is NOT compatible.
Compatible memory here:
http://eshop.macsales.com/MyOWC/Upgrades.cfm?sort=pop&model=156&type=Memory&TI=3 759&shoupgrds=Show+Upgrades
If you use a 160GB drive, Tiger or Leopard, you will have access to 137GB after format.
The 160GB drive is fine, as you only lose about 10GB due to drive capacity support limits of the machine.

I am looking to buy more ram for my macbook, but I don't know what to look for. Do I have to buy 2x 4GB and get rid of my old ram or I can buy 2 x 2GB and use them all together?
Also, same with HD. I need more HD as well. Can I install another harddrive as well?
Message was edited by: Strato222

There are only 2 slots for RAM. So, you'd need to replace one of the 2 GB sticks with a 4 GB stick for a total of 6 GB, or replace both for a total of 8 GB.
Yes, you can replace the HDD with a larger one as well. There are instructions in the manual.
