Ram slots on a G-5

How do ram slots J-43 and J44 relate to the numbered slots inside the machine 1-4 upper and lower on a G-5?

If you're sure the RAM is good, try the Hair Dryer trick...

Where do i find the second ram slot on a t43 thinkpad

i believe ram might be my issue causing my t43 to freeze moving the mouse pointer with the track pointer helps get things working i bought a new 1gb ram and installed it in the ram port since then i have been able to run sluggish applications more smoothly but after a while of using these applications up to an hour the t43 freezes using the track point put some life back in to the machine (enough to close the application) when i dont have anything running except the internet it runs fine i believe the t43 has some sort of second ram slot since in the system it now shows as 1.5gb of ram and not 1gb
should the t43 have a second ram slot how easy is it to get at i don't want to accidentally break something

Welcome to the forum!
The second RAM slot is under the keyboard. Check the HMM for removal instructions:

Accessing ram slots on a 27 iMac

I just received a new 27 iMac and I’m thinking about adding an additional 4GB of ram. I’m not very excited about laying this big boy down onto its face to add the extra ram. Is it possible to place the machine on the edge of a table and tilt it back to access the ram slots?

Thanks for the responses. So I agree with you guys about following the directions. I'm trying to visualize the best way for my wife and I to tip it onto it's face. Should I hold the sides while my wife holds the arm in the back? Or should we each take a side? I'm trying to avoid getting a bunch of finger prints on the screen or stirring up dust that might exist inside the machine.
I know I might seem overly paranoid but it's been four month ordeal for me to get where I'm at right now. I would hate a screw something up at this point in the game.

RAM slot failure on a Equium P300-16T

Hi, Ive got a RAM slot failure on a Equium p300-16T. I have tested both RAM modules and there in perfect working order. RAM slot 1 works and laptop boots successfully but as soon as RAM module inputed into RAM slot 2 no boot.
My frustration comes from when i began a warranty repair on Friday night through the website and it refused to accept it stating that the server had timed out. Unfortunately this timing out seem to happen every time i went to finish the warranty claim. And to my dismay my Serial number is no longer available on the website due to the warranty running out today (2nd of August).
Is there anything i can do?
Kind Regards

What size RAM are you installing?
The system is capable of 2GB Max in total, so if you are installing RAM above 2GB, booting will/may fail.
You may be able to install a 2GB Module in Slot A, but it will probably be unstable and cause intermittent BSOD's. Or not boot at all. (not recommended)
I believe your laptop has the Santa Rosa chipset, which requires RAM in at least Slot A.
If you install RAM in Slot B only, it wont boot.
So basically to get the most out of the system, you should have a 1GB Module in each slot, which is how it comes from the factory if the specs found in google are correct.

MacBook Pro mid 2012 15" - one RAM slot gone bad

Hi,
Has anyone ever had the issue with not working RAM slot? My MacBook Pro mid 2012 (non-retina) suddenly froze and after restart was beeping three times every few seconds. I found out that the beeping signals bad RAM. Bought new chips, and the problem still exists. My mac can now run on one slot with 4GB RAM.
I did check the placement of the chips in the slots, i also checked one slot at a time, and one of them has gone broken.
Any ideas on how to make it run again? or if it is possible to replace the slots?

The Apple-accepted cure for a dead RAM slot is a new logic board. Unless you ahve AppleCare, that will be an expensive fix.
An Apple service option is the "depot repair." Instead of working on your computer in the Apple Store, they send it to a centralized refurbishment facility where they fix anything they find wrong (except for cosmetic damage and damage from abuse like dropping) for a flat fee of a little over US$300. That is between 30 and 40 percent of the parts and labor charges if Apple installs a new board in an Apple Store. Sometimes they will install an new battery at the depot without increasing the flat fee.
The downside is that it takes about a week; for that level of cost savings, I could do without my computer for a week.
So take it to Apple and ask about a depot repair.
A low-tech and low-cost option is to expand on what you are doing now--using one slot. Although the official RAM limit on your model is 8GB RAM (two 4GB models), your model can actually handle a total of 16GB (two 8GB modules. You can ignore the dead slot and put an 8GB module in the good slot. My 2012 MBP has 8GB RAM and is completely happy running Mavericks.
Be sure to ONLY get the RAM from an Mac-savvy vendor. For over a decade I've bought all our Mac RAM from one supplier. This is their page for an 8GB module for your MBP model:
http://eshop.macsales.com/item/OWC/1600DDR3S8GB/
I would also trust Crucial on this one. For a change they recognize that your model can use more RAM than stated in Apple's outdated specs:

How to fix a malfunctioning RAM slot?

I tried to upgrade my Mac Mini (late 2012) from 2 x 2GB to 2 x 8GB after ordering the correct Crucial RAM from Amazon, based on user reviews. After my first installtion attempt, I found that the Mac mini would only recognize only one of the 8 GB sticks. The Blank 1 slot was listed as empty when in the system information retrieved via apple menu. So I repeated the installation 3 times but after the third attempt the Mac mini would start and beep and the monitor screen was black. So I reinstalled the old RAM and the Mac mini would beep again after turning it on. Upon closer inspection, I noticed that the top RAM slot wasn't holding the RAM tightly and the left clip plastic piece was little more flexible than the bottom piece. So I removed the RAM and inserted it at 45 degree angle and pressed hard so that it popped in place. Yet the Mac Mini beeps upon start. Even if the top slot is damaged, it doesn't want to run on the bottom RAM slot which seems to work fine. I purchase the Mac Mini in Feb 2013 and just spent over $100 to upgrade the RAM. It's a shame I will have to shell out more to fix it. Any suggestions?

The Mac Mini started with the original RAM after I had sealed the hardline crack with some lactate. The release and hold mechanism for the top slot became stiffer after that. The Crucial RAMs didn't work but I am happy that the mini can start with the original RAMs. There were over 2000 5-star reviews for the Crucial RAM on amazon but the latest reviews are negative suggesting drop inequality or compatibility issues. I am going to return the Crucial RAM and be content with the 4 GB RAM for now.

Help with ram slots on MSI P7N SLI PLATINUM

rig config:
MSI P7N SLI PLATINUM (MS-7380)
bios version: 1.3v
Q6600 quard core 2.66GHz
Zotac modded 9800GTX+ amped version
2x2 Gb DDR2 800MHz Kingston
500 watt (absolute) power supply (taken form an old HP workstation)
windows 7 X64
Everything's on stock setting
Its been almost 1 & 1/2 years since i bought this rig, and from first month itself i have been having problem with the ram. The problem is not with the sticks, its with the ram slots. There are different things that happen. Sometimes when i boot my system:
1) either, it wont start, i.e. no boot screen.
2) It will load upto windows startup screen, crash and restart in an infinite loop.
3) It will load windows, then crash after sometime.
4) If i run any memory diagnostic, it will give errors.
At these times, i take out my 2 ram sticks, tinker with them, place them in different combination of ram slots, try push them in, in a certain way, keep trying until it yields and it boots up again ( generally a process of 1/2 an hr to an hr). After this my system will work fine ( no errors on any memory diagnostic) and boot properly for a week or 2, maybe even a month, but then again the same problem happens. I know for sure that there is no problem with my dimms (have checked them in other system and they work fine), its something to do with ram slots, or memory bus-controller structure.
Recently the problem happened again, though my tinkering didn't help. My system only boots up if i place any of the ram sticks in the 3rd slot (the 1st orange one). It wont work for any other slot and neither will it work if i place both of the sticks together. I have tried resetting my bios as well cmos settings, but it has not helped. My mb is still in warranty, but if i give it for repair, it will be gone for a good month or so, which doesn't go well with me. If someone has any suggestions, or a way out, it will be highly appreciated. Please help!

yes the psu has a single +12v rail with 21A rating, but somehow i don't feel the problem is because of it. When my system successfully boots, it works properly. I can play or work on high performance softwares for any number of hours without fail, which ought not to happen if the psu is bad.
Hmm, you are ignoring the possibility that your PSU is "flaky" (that's a technical term)!!!! You've never had any gizmo where "sometimes it works and sometimes it doesn't work"?
If you don't want to buy a new PSU then at least beg-borrow-steal another one and see if your symptoms change.

Power Mac G5 Dual 1.8 PCI (4 RAM Slots) - want to upgrade to 8GB?

My computer is a Power Mac G5 Dual 1.8 PCI (4 RAM Slots)
Is there any way I can break out of the 4GB RAM limit into the world of 8GB RAM without having to buy a newer computer. I need to open a large 4.5GB TGA file in After Effects (48000 pixels x 36000 pixels).
Failing that, is there an application like RAM doubler I could use temporarily to get me though this job?
Power Mac G5 Dual 1.8 PCI (4 RAM Slots) Mac OS X (10.4.10) Currently have 4GB RAM installed

If there is not enough RAM, OSX will use space on the disk drive, so the amount of RAM should not limit the file size an application can handle, but speed will be reduced. 32-bit addressing can restrict the use of huge files, but there are ways that applications can get around it (at the expense of lower speed).
If After Effects has a file size limit, extra RAM will not help A later version (maybe using 64-bit mode) may handle larger files. 64-bit applications can be written to run in Tiger on G5s, but will be easier to write when Leopard is released.
You may be able to use some other application, such as Photo Shop, or Graphics Converter, to extract part of the TGA file, or reduce its size by changing its resolution, so you can use the result in After Effects.

Mac Mini Bottom Ram slot sits improperly

Nevermind... problem solved.

What worked with me with 2 x 4GB ram from OWC:
1) Remove stock/old RAM from both slots.
2) Inserted new stick of 4GB ram on top slot (in my case, this slot had no problem recognizing the new sticks).
3) Leave the "buggy" RAM slot open.
4) Start the mac mini up, performing the NV/PRAM reset (holding down Option + Command + P + R)
5) When OS X boots up, shut down the mac mini.
6) Insert the other stick of 4GB in the buggy ram slot.
7) Restart the mac mini normally, not holding down any keys (normal boot).
8) Profit
Absolutely sailing on 8GB of OWC ram now. Sure, I've pulled hair out, RMA'd probably perfectly fine RAM with Newegg, and still clench when I restart the machine, but hey. This thing wasn't really meant to be opened, right?

Are all 4 RAM slots USER-UPGRADABLE in 27", 2.8MHz, i7 iMac?

I haven't dug into my iMac yet but am wondering if all 4 RAM slots are user-upgradable... before I fork out the money for more RAM.
Currently I have 8GB (4x2GB). I thought the 8GB would be enough for the graphic designing I do (was managing with my previous 1GB on my other iMac), but quickly found out that I need a lot more. The max is 16GB (4x4GB).
Anyone know if ALL four RAM slots are USER-UPGRADABLE?
Thanks!

Yes, look in your manual and it will show you how that all four slots are user upgradeable. If you want to upgrade to 16 GB you will need 4 x 4 GB chips. OWC's memory is highly regarded on this forum because they specialize in Macs and provide quality products and service. Memory there can be found at:

Second RAM slot bad?

Troubling issue with my 24" iMac (late 2008, 3GHz, nVidia 8800).
With both RAM slots loaded, it crashes randomly in the first 15 minutes after boot. Sometimes this is a freeze, others the black "You must restart your computer" message. Regardless, after shutting down, it won't reboot successfully until the RAM has been re-seated (it'll stall at the plain gray screen, before the spinner or the Apple logo show up). Once re-seated, sometimes 2-3 times, it'll decide to boot again, only to suffer the same fate.
Brought it down to the minimum configuration - only the first slot filled. Works fine, rock-solid, runs for weeks without issue. Swap that same stick to the second slot, and we're back to crashing and needing to re-seat the RAM to get it rebooted. I've tried both 1GB sticks that came with the iMac, as well as a couple of 2GB sticks from Crucial - the behavior is the same regardless of the stick(s) being used. (All sticks are known to be good).
I've currently got one of the 2GB sticks in, been running for about a month without issue, but I'd really like to get the machine up to 4GB, so it's about time to get this fixed.
Aside from the testing I've done above, is there anything else I should do prior to setting up a time to drop it off at the local Apple Store for warranty service (still under the 1-year warranty, haven't bought Applecare yet, but planning on it)? Any other tests I should run or documentation I can provide to save both my and the tech's time?

So, it's been a month. Figured I should post an update on how things turned out.
Repaired permissions, backed up to an external drive, booted from it to be sure, and repaired permissions again.
Shut down, removed the backup drive, and decided to give it one more try before calling up the store. Performed the same procedure I've done so many times:
Unplugged the power cable. Let sit for 20 seconds (resets SMC).
Popped out the single 2GB stick from the left slot, seated it in the right slot. Seated the second 2GB stick in the left slot.
Plugged the power cable in.
Booted. Reset PRAM. Came up OK, did not log in. Shut down.
Booted again. Reset PRAM again. Came up OK again. Logged in this time.
From this point on, everything has worked flawlessly, across multiple reboots, for a few weeks now. I've run several memory tests, each of which has passed with flying colors.
I'm not sure exactly what the difference is this time around, but I'm certainly not complaining.

Ram slot problems

I don't know if anyone else has had this problem, but this past December I noticed that only one of my 2 ram slots was reading the RAM card. I sent my computer in to the Apple Depot on 3 different occasions (the first time, my computer came back showing all of my RAM, but the computer crashed every 1-5minutes), then I sent it back and it came back running smoothly with 1 of the 2 RAM slots not reading (Read: original problem). Finally after the third time, I got my computer back and it ran without crashing and all of my RAM was accounted for (both 512MB chips).
That is.. until one week ago. I moved to Germany and when I got here, things were going slow. I went to the apple menu and selected "About this Mac". Low and behold, only 512MB RAM appeared.
My first thought is that I burnt it out because my computer heats up a lot fairly often (but my batteries Serial# doesn't fit the exchange program's criteria, mine is: W7339SKNNXOB. The computer's serial# does comply, however).
My more absurd explanation is this occurred on both occasions right after I flew somewhere and the computer got X-rayed.

Well, here's what Apple's PowerBook Service FAQ has to say on the subject:
Does Apple warrant my PowerBook service?
For PowerBooks under Apples One-Year Limited Warranty, Apple warrants against defects that arise from service performed for 90 days from the date of service or for the remaining period of the warranty, whichever provides longer coverage for you.
b For PowerBooks not under Apples One-Year Limited Warranty, Apple warrants against defects that arise from service performed for 90 days from the date of service.
So, at first glance, it would appear that if your repair was done in February, the 90-day warranty period might have expired. But, maybe there's an additional warranty (hopefully a longer one) that applies to the parts (i.,e., the logic board), and so the cost of a replace
b part
if not also the
b labor
would still be under warranty.
90-days seems awfully short to me, maybe it would to someone at Apple (a customer service rep, e.g.) as well if you make a good case in a persuasive way. That may be another option, albeit one with limited chances of success.
That's the best I can tell you right now; perhaps there's someone on here with actual first-hand experience with getting a repair by Apple on an out-of-warranty PB RE-repaired who can give you more insight.

Flashing light, dead RAM slot

Hi all,
So I woke up this morning to an unresponsive computer. I noticed the light on the front panel was flashing at an even, quick pace. After some research, I fiddled with the RAM (reseat, switch, PRAM, etc) and finally came to the conclusion that the bottom RAM slot is dead (not the RAM board). The computer will start now, but nothing shows up for the bottom RAM slot, even though there are RAM modules placed there. Is this a dying logic board?
Mac Pro, 2007
Thanks.
John

Not necessarily. A damaged RAM slot is not a sign that your logic board will fail, but the RAM slot is part of the logic board, so you can say that a small part of the logic board is failing.
You can carry on using your Mac if the rest of the RAM is enough for your tasks, but make backups of your files with Time Machine. If not, take the Mac to an Apple Store or reseller

[Solved] MSi GT60 Dominator (non-3K) - RAM Slots

Anyone knows where the primary RAM slot is located ? I'm want to replace the stock 8G Kingston RAM with a 16G Corsair Vengence which i already own. I can only see 2 empty slots when i open the bottom lid.

PPC Dual 2.0 Ram/Ram slot problem

Hey there folks. I'm hoping someone has seen this before and can help me out. I've been having problems with RAM. It's a mix of bad ram and what I believe are bad ram slots. I've isolated the bad ram and removed it from the machine. With the good ram I have found that every other slot has a problem. If I put a pair of good ram in the Zero slots, it works fine. If I put them in the next slot they show has having a problem in the hardware test AND if I just let the machine boot, the ram will appear in the hardware profiler, BUT it will only post half its value. The machine will run fine for a bit, but then applications will vaporize, there will be eternal SWODs..etc etc .. making the machine unusable.
I've got a work-around for now. I just use the first and third slots and leave the second and fourth slots empty.
Any ideas on what the problem is? ... How to fix it?
Thanks very much for your input.
Cheers,
Jeff

yeah.. I don't think the Crucial memory will work in those slots either... I haven't tried, but all the ram that seems good and works as a stand-alone pair in the first and third slots, doesn'twork in the second and fourth... I'm much more suspicious of the motherboard/memory slots...
