RAM for Apple Notebooks - Page 2

Edit: Wtf? Then I type something in all caps I mean it to be in all caps and I don't appreciate it being changed. How can I fix this?

i'm planning to get a 13" macbook that comes with 2x256 ram. does anyone have specs on the cas latency, voltage, and ECC on that ram? i am planning to replace one of the sticks with a 1 gig ram, but i want to match the latency, voltage, and ECC to make sure there are no issues. apple website doesn't give much detail. thanks!

www.crucial.com will tell you all you need to know.

ok, does the ram in the macbook and macbook pro really need to be installed in matching pairs? i've been hearing/reading about some dual-channel thingamijiggy...

No.

If the RAM is the same speed and size the machine should automatically take advantage of the DDR capacity, but it's not necessary that they're the same brand or anything.

right on, traidone. you hit it square in the head

i bought a gig of ram from Best Buy last week and it works perfectly. just make sure they give you the right kind. i wrote down exactly what i needed 200 pin, 1 gig, ddr2 667 MHz and the idiot working the memory section gave me a 512 mb 240 pin stick. i was like are you an idiot i gave you what i needed. so then i went behind the counter and picked it out.

Have a question:... a "test" you might say to see how smart you Apple guys are...

(I would assume the below info would be a worthwhile addtion to the Sticky.... Having ram that will work arcoss platforms is the smart thing to do)


Can the RAM from an Apple MacBook Pro 1.83GHz Intel Core Duo (15.4-inch) be used in a HP nx6325 (RB526UT#ABA) ?

HP nx6325 (RB526UT#ABA)
(DDR2 667 MHz) SODIMM


I'm assuming the Apple ram is 200pin, standard DDR2- 667 spec notebook size ram.... 1.8v

Concerned as in the first post of this thread there's a mention of ram being optimized? for Apple products?


As long as the timings are the same, the voltages the same as a Windows type machine it should work, and may I say it would be pretty stupid for Apple to use non-standard ram... So I doubt that the ram from the Apple wouldn't work... in the above HP.


Here's the ram I'm talking about... Most all vendors showing what appear to be desktop ram, but saying it's 200 pin, 667 spec...

ACP-EP 2GB DDR2 SDRAM Memory Module
Mfr # MA091LL/A-2GB

http://www.ritzcamera.com/product/EP4515545.htm


CPU-Z shows the current installed ram in the HP to be:

Under MEMORY TAB

DDR-SDRAM (Channels #DUAL)
Size 512 (1 module)
Timmings
Freq 99.8mhz
FSBRAM =CPU/8
CAS#Latency (greyed out)
RAS# to CAS# Delay=4 clocks
RAS#Precharge= 5 clocks
Cycle time (Tras)= 10 clocks
Bank Cycle time (Trc)= 9 clocks
DRAM idle timer= 4 clocks

Under the SPD tab

Slot #1 DDR2-SDRAM
Module size 512mb
Max Bandwidth =PC5300 (333mhz)
Mfg = 7F7F7F7F7F510000
Part#=64T64_20HDL3SB
64T64020HDL3SB

SPD timings table:

333mhz
CAS# = 5.0
Ras to CAS= 5
RAS# Precharge= 5
Tras# =15



Any input would be apperciated. I've heard over the years that Apple owners are a pretty smart bunch...

The above looks like standard DDR2 notebook ram to me, but I need a confirmation that "APPLE" ram isn't some weird bastard stuff before ordering..


.

It is standard ram.

At the time I posted I thought I had a lead on the above ram, 2 gig worth for $141.29 shipped.. . so I was in a rush.

After I had confirmed my order, I was planning on posting the link to the deal, but it looks like the deal is dead.

Thanks for the info and your time, it is apperciated!!!

Anyone know where to get semi-affordable 2gb stick for the new MBP? I would love to bring this puppy up to its 3gb max if possible.....but I don't know if $500+ is worth it cost/benefit-wise. Any input?

I am looking into getting a new Apple macbook 2ghz core 2 duo w/ 1 gig of ram .. i don't have much experience with macs aside from the 1337 apple 2's i grew up on in grade school. the question is, for average use (web browsing, docs, lots of iChat AV, and moderate use of iLife '06) is 1 gig of ram enough? any ideas on how memory hungry mac os x is compared to windows xp? i have a windows laptop (xps gen 2) so parallels wont be necessary. Thanks.

1 gig is more than enough for average use.

But what about the difference when using moderately intensive programs or having 12 programs running at once? Is this more a CPU-intensive thing, or will the extra 1g of RAM (from 2g-->3g) make much difference?

not so sure about mac, but winxp's sweet spot for ram is 2 gigs; anything over that is pretty much never used. I have virtual mem set as low as i can (0mb in config, but truly disabling the page file just isn't a good idea) and i never run into low memory errors; even while playing bf2 at full settings (which is a particularly memory hungry game). vista, is going to want around 3.5 - 4 gigs; but again, i have no idea with mac specifically. My experience with Gentoo Linux also makes me feel that 2 gigs currently is the sweet spot for most uses. To answer your question, multi tasking eats ram as much as cpu if the programs you're running multiple instances of are doing something. (Ex. 12 web pages loading at the same time are all going to eat your ram, and top out your processor; where as 11 web pages idle and 1 loading is going to consume far less processing power, but only slightly less ram.) .... assuming things work similarly between win/Linux - and os x.

That is helpful.....I run 2gb of high-end (Corsair's X-Treme) in my WinXP machine & it is quite snappy.....(although, I think the MBP is still snappier). I am just wondering if the cost/benefit curve goes the wrong direction when going from 2gb-->3gb.

i think it does. but mac os x is Unix based, not Linux based, small differences, but it could make a difference. As a note, win xp home can only address 3 gb of memory, xp pro x64 and i *Think* xp pro x86 can address more; where on the other hand Linux and Unix have been able to address far more, for a long time.

Can anyone link me to the ram for MBP and MB?
Thanks in advance!
[Edit] Would ram from my 5720 be equivalent?
