However it seems like OSX does eat up quite a fair bit of memory and Rember doesn't seem able to find the fault when I am running on one stick (it is probably used up by some block of code that has yet to run yet!)
Is there such a thing as the equivalence of memtest86 for Macs? Or even better will memtest86 even boot on a Intel Mac, now that it supports BIOS?
get it while it's hot. It is a beta release, mind you, but at long last an official, and current, OOO port has been released.

is there a good program to test the new 4gb of ram i have just installed in my new macbook book is all working ok?
View 8 Replies View RelatedWhatever your situation is, if you need to test your RAM, Memtest OS X is the best tool for the job for your Mac. Yes, there's Memtest86+ - I always use that for all the PCs I own. However, there's a bug in Memtest86+ where it could give false positives on EFI machines (which all Intel Macs are).
Memtest, by the way, is open source. So why, then, do you have to pay to download it? You have to pay to download both the binary and the source. I believe this violates the GPL, which Memtest OS X, and Memtest before it, are released under.
So I'm attaching Memtest right here in this thread. Now you can download it for free, without having to pay. Unfortunately, I don't have the source .
Is there any way that I can install the boot camp HFS driver on my non-Mac PCs?
Anyone know what the driver's setup file might be called, since there seems to be several boot camp setup EXEs on the Snow Leopard disc?
I upgraded the memory in my macbook and was wondering if the old memory could be used in my dad's Dell Inspiron 6000 laptop? Below are the tech specs for both laptops
Dell Inspiron 6000 Laptop
RAM
Installed Size 512.0 MB / 2.0 GB (max)
Technology DDR2 SDRAM - 400.0 MHz
Memory specification compliance PC2-3200
RAM form factor SO DIMM 200-pin
RAM configuration features 2 x 256 MB
Macbook early 2008
1GB (two 512MB SO-DIMMs) or 2GB (two 1GB SO-DIMMs) of 667MHz DDR2 SDRAM; two SO-DIMM slots support up to 4GB
Will the old memory from the macbook work in the dell?
is the memory, that comes with mac mini, ECC?
View 2 Replies View RelatedThe first time I use my 80 GB Macbook Air I found only 55 GB available! I suppose that the system would need a maximum of 5 GB. Where did the rest of the memory go?
View 2 Replies View RelatedI know there have been a lot of posts about installing additional memory - I even watched the installation video over at OWC. OWC video shows two factory 1GB memory sticks - one in Slot A of the upper riser board and one in Slot A of the lower riser board. It says to move the module from Slot A of the lower riser board and install it in Slot B of the upper riser board to make a matched pair.
But here's the question. I have 4GB of RAM - two 1GB modules in Slots A&B of each riser board from the factory (I know - I know - I should have ordered it with the stock RAM and purchased the extra at less than the exorbitant prices Apple charges - but that's another story). I want to add 4GB more (two 2GB modules):
Move the two 1GB factory modules from Slots A&B of the lower riser board into Slots C&D of the upper riser board and then install the two new 2GB modules into Slots A&B of the lower riser board (just as the OWC video implies)?
Leave the factory modules where they are and install one 2GB module in Slot C of each riser board to provide a "balanced" 4GB on each riser board?
Options #2 seems to provide a "balanced" module location (4GB in the upper riser board and 4GB in the lower riser) so the four cores on each CPU can access an equal amount of memory for optimum performance. - but I have read that you need to install the new modules in matched pairs - but does that mean put them together on the same riser board? In the OWC video, if the two new modules were a matched pair then why wouldn't they be put one in each riser board just like the factory modules?
Ok i just want to make triple sure that this ram will indeed work in my imac 20" 2.0 (late 07 model) which uses ddr2 pc5300 667 200 pin ram.
The only thing that is striking me odd is that this is the only ram on neweggs site that seems to be compatible with an iMac that doesn't actually show up under their Apple > Mac Memory category
I have an old 12" G4 1.5 PowerBook that I want to upgrade the memory. On the Crucial website, I see a 2GB DDR333 module. Is it compatible?
View 2 Replies View RelatedSo I finally went to the Apple Store and got my very first Mac, a MacBook Pro 13" .
Anyways, I got the baseline configuration that came with 4 GB of memory. Playing with the Activity Monitor, I noticed that after awhile of using the computer, the green "free" memory piece of the pie becomes progressively smaller until it's almost gone. Does that mean I have no more free memory left? But I'm not running a lot of programs at once. Just Safari and iTunes, maybe Pages too.
I know that the iFixIt tear down reveals Toshiba flash chips on the 11" MBA, but I was curious to know the following specs on the 13" MBA.
Does Apple use different suppliers for the different capacities/models (i.e. Samsung, Hynix, etc.)
I could make some guesses from the benchmark tests, but would like to have hard specs.
I tried contacting Apple, but the only thing they would tell me is the capacity available for purchase. I also don't have the guidelines to reference the flash specs based on the model of the Toshiba flash.
Can all versions of the iBook G4 12" use PC2700 RAM? Even the 800GHz and 1.0 GHz models? I know you're supposed to use PC2100 in them, but the PC2700 is so much less expensive than the PC2100 right now.

i have 4 gb of ram, and would like to increase the shared video memory in windows 7, that i am using via boot camp. i know you can do it using the bios, but because there is no bios, is there any program that emulates the bios for boot camp, or another solution to do this?
then, why does windows 7 read just 3 gb of ram, when i have 4?
3yr old black MacBook has bad memory slot. Will not boot with chip installed. Tried swapping chips and slot 1 or 2 and its the slot. So at least computer works. What are the odds 2nd slot will fail? Is that rare? Is it just a bad solder connection on main board for memory terminal? Or some tiny hidden board trace or other hard to find component?
View 3 Replies View RelatedI've done a lot of research about the older USB iSub (which I have) not working with Snow Leopard and Intel Macs (which I also have). I tried the iMic work-around, but it did not work for me. Any tips? Maybe I'm missing a step...
So anyway, the newer iSub as paired with the HK Soundsticks works fine w/Intel Macs since it uses the industry standard 3.5mm mini-jack.
I was wondering if anyone has considered converting the guts of the older USB iSub to use the 3.5mm mini-jack instead?
I have a crappy speaker/subwoofer combo that uses the 3.5mm mini-jack where the subwoofer volume is controlled at one of the speakers. It looks pretty easy to pull the guts from the crappy subwoofer and see if it will drive the iSub. A bit of a kludge I admit, but it's possible w/o permanent damage to the iSub.
Can anyone tell me or post a pic of how all the wires connect between computer/iSub/satellite speakers on the newer HK Soundsticks?
My 17" ALS Imac is not booting (tiger OS). I will preface this by stating the hard drive has been whining and making a lot of noise for the past year or two. Anyway, a few days ago it froze up and I had to pull the power plug. I tried to restart and got a plain gray screen and saw a question mark. Now when I try to retsart I get a plain gray screen with the following message:
Invalid memory access at: 0SRRO: (then a long address)
WELCOME TO OPEN FIRMWARE
To continue booting type "mac-boot"
To shut down type "shut down"
After I type mac-boot the hard drive (or cd drive?) starts racing quite loudly and then it freezes up and displays a grayish screen with dozens of short, yellowish, horizontal lines and I have to pull the plug again. I have been anticipating a hard driver failure for a while so at first assumed that was the problem, but now I see this memory error and am not so sure. I was planning to purchase a 1 TB drive and maybe upgrade the OS at the same time . Basically I am wondering if I should go ahead and do this or run some additional diagnostics first in case it's something else?

MacBook, Mac OS X (10.5.8), 1tb HDD, 1 gb memory.
my macbook pro (late 2011) is powering down without warning. I'll be writing an email and w/o warning, it's off. I'm unable to turn it back on with the power button unless i hold it down for a slow count to 10. Fyi - machine is 100% charged when this happens. Two days ago, I did SMC and PRC resets with Apple Care. I needed to do both of these again yesterday on my own.

My macbook pro (a1150 series) has started to act out of line and just when i think that I have it figured, the odd behavior starts giving symptoms of another problems. I.E- slow computer behavior indicates bad HD but then it acts more like it didn't have enough ram. So... I want to test the machine from top to bottom.

So, if there is a video card enthusiast in Hollywood,CA area who has an EFI-64 Machine and would like to be part of this experiment, PM me.
FYI...there is a good chance this will work...on the other hand, there is also a good chance that Apple/Nvidia/EVGA placed an additional STOP to flashing and upon boot we will see a lovely black screen.
Whats in it for you? Immortal, undying glory ! A beer ! And when I figure out full process, I will make one for you with GTX285 you bring me. gratis
I have removed the 128K chip it came with and installed a 256K chip. I then flashed Mac EFI ROM onto it. On my first Gen it runs exactly as before. Boots into OSX with help of Netkas Injector Package, but not until desktop. (also requires additional Nvidia card)
It appears to be ignoring the Mac EFI due to it being 64 instead of the 32 it "requires".
Aperture 3 runs as a 64-bit application on Mac OS X Snow Leopard on Macs with Intel Core 2 Duo processors.Does that mean that Aperture 3 won't run as a 64-bit app under OSX.6 on quad-core machines (like the top-of-the-line i5 iMac)? They can't be serious!
