T440 MS + MMS Types - Checking RAM Slots

Hi!
I'm currently upgrading the memory in our companies laptops. So far I've already done about 80 T440's with probably another 20-60 to go.
Is there any way to check if the laptop is the MS or MMS type without taking the battery off?
If not is it safe to take the external battery out while the laptop is switched on and plugged into the power pack?
We're putting 8gb chips in the MS types, then taking the 4gb chip and using it in the second slot of the MMS types. It's quite disruptive to have to physically go to every laptop and shut it down or ask the user to check - especially since a lot of people actually work remotely.
I tried using the command prompt but it only shows the slots actually in use, not the free slots. I also tried running a script since I have admin access to all the laptops on the network but although this can work there's just too many logistics issues to sort out to make it happen (time is precious).
Any help would be greatly appreciated!
Solved!
Go to Solution.

You should be able to use WMIC to pull information on the model number as well as the memory configuration of the machine.
The external battery is hotswappable; otherwise Power Bridge wouldn't work.

Kernel Panics - testing RAM slots

After frustrations dealing with constant kernel panics, I have gotten Apple Hardware Test to identify that one RAM slot on the G5 iMac is probably defective. Each slot carries a 500Mb chip from Crucial.
The test indicates a RAM error/defect in DIMM slot 1, but when I SWITCH the two chips, it is still DIMM slot 1 which comes up as defective.
Questions:
Which of the two slots in the 20" G5 iMac is DIMM 1, and which is DIMM 2?
Do others agree that if the chips themselves were defective, a switch would have changed the id of the slot exhibiting the error?
If we elect to repair the DIMM slot, how much hardware must be replaced? Tests here and in the Apple repair shop consistently say the logic board is fine.
If I can identify the good slot, and put in a single 1Gb chip in that slot and leave the other empty, will things get by ok?
Thanks in advance for all the help. The OS has been cleanly reinstalled numerous times, and I've been sold a replacement HD I suspect may not have been absolutely necessary, though it is nice to have the larger capacity.
Owen in Oregon, at the end of his rope.

You are on the right track by swapping devices from one slot to the other, but you've not definitively identified a slot issue as opposed to a DIMM device issue, as you report that your devices are identical. While the evidence still points to that, it would be helpful to swap in a different type of compatible memory to pin down the issue.
If you slot is indeed defective, only the logic board need be replaced. If your machine is under warranty or an AppleCare extension to it, Apple will replace the defective logic board at no cost for either parts or labor. You can identify which is DIMM slot 1 and which is two simply by leaving one empty, restarting and again launching the System Profiler. If it panics, swap the single module to the other slot and leave the other empty, restart and again check with System Profiler. I believe that slot identifiers are screened on the board and that the right slot is slot 1, and the left, slot 2. But, I am not certain that is the case.
There may be an issue with seating modules in what appears to be defective slot, with the clips that lock them into place, with the edge connector itself or with the UL3 memory controller, if your DIMMs are not defective. There may also be material obstructing the slot in question, so examine it carefully to determine that no foreign material or debris is present.

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:

Is this the correct type of Ram for a mac mini?

I have a 2007 Mac mini, and want to go from 1gig to 2 gigs of Ram.
I currently have 2 512's
I need to know 2 things. (i'm pretty sure on both but i'm not a huge hardware guy to bare with me)
1. Will there be any compatibility problems? I.e if i upgrade to 2 gigs will it even help or because the rest of the computer is not being upgraded will it be useless?
2. If i'm good to go, Is this the correct type of Ram? http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=4E665783A5CA7304
Not sure if these are needed but will post anyway:

Thank you in advance <3

NO, it will NOT work.
You have to find the memory specific for Mac, and rule of thumb, Mac Intel chips usually take "ECC" memory. On occasions, You can get away with Non-ECC (on certain PPC Power Mac G5 towers) -- You can check on-line stores, like Newegg, Tigerdirect, or Goolge search for the Mac Mini memory. I got mine (for my two Mac 2,1) on line, and I put 4G (2x 2G), although only 3G was available.
It is worth of upgrade it. just need to find the right memory.

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:

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.

I am looking to make the switch from pc to mac and have been eyeing the MBP 13". I would like to know whether it is fine to add RAM and SSD myself? any compatibility or warranty problems? what brand/type of RAM and SSD is the best fit? thank you.

Chamar wrote:
I'm possibly wrong here but I suspect opening a brand new MBP to add parts yourself will void the warranty. It is probably in the small print. I certainly would not risk it for an expensive Apple product.
Some (Windows) laptops have easy access to memory and disk slots that do not necessitate taking the complete back cover off. However, Apple does not make life easy for you.
However, if you are going for a 'used' machine it is probably worth a try.
Not possibly, definitely wrong, Ram and Hard Drive are considered user replaceable and will not void the warranty if changed.

[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.

2 are under the keybaord and 2 under the notebook.
Same for all GT70 and GT60, doesn't mate 0NC, 2OE, 2PC, etc

What specific type of RAM does the Power Mac 8600/200 take?

What specific type of RAM (Memory) does the Power Macintosh 8600/200 take? If known, where could I get a hard drive for that Power Mac? eBay???? Any help would be gladly appreciated!!
Thanks,
Sean Butler

Sean,
Craig refered to MacGurus. Here is their website:
http://www.macgurus.com/products/motherboards/mbppc8600.php
You will find valuable information there.
Just a word of caution. If you have G3 memory chips and chips for the 8600/9600 etc. side by side, they will look almost identical but the registration notch is 1/16 of an inch off. Do not force one into the other machine. The real easy way to distinquish the 8600 memory chip is the two odd silicon chips in the middle that are not the same as the other standard RAM chips lined up on either side. They are parity checking chips, if my memory serves me correctly. The G3 memory modules will have identical chips all the way accross.
Be sure and follow the other links like:
http://www.macgurus.com/products/ram/edodimm.php
for a complete run down on EDO chips.

This page shows the G3, PC 100 compliant RAM chip:
http://www.simmtester.com/page/news/showpubnews.asp?title=Isyour+Memory+Module+PC-100+Compliant%3F&num=28
The chips for the 8600 will have more space in the middle and will have two non-conforming or mismatched chips in the center.

Ram slots not working after CMOS reset

Im using MSI K9N Neo V2 mb, and it was doing fine until i reseted CMOS. Now 3 out of 4 ram slots are not recognized by BIOS nor Windows. Im sure that ram memory is ok, cause ive checked all of it by replacing it between ram slots, and they're only working in slot nr 4.
I know that the MB is old, but everything was working fine, and suddenly went wrong after CMOS reset
Things i did to fix:
Updated BIOS
Msconfig memory uncheck box
Cleared CMOS with jumper
Replaced CMOS BAT
Checked if smth's wrong with cpu
Cleared RAM slots with rubbing alcohol
System wont even boot without memory in DIMM 4 (ram slot 4), and BIOS only recognizes memory in DIMM 4
This is really frustrating, because there is no reason for smth to not work all of a sudden
Any help? Tnx

There is a known issue with Powerbooks with the lower memory slot failing, and it sounds like yours may be starting to fail. At one point there was an Apple recall for a small sliver of Powerbook systems to fix that.
The alternatives are to run with 1GB in the upper slot, try one of the internet vendors that say they can fix that (check references), or install a used logic board. I don't believe Apple is repairing Powerbooks anymore, so if you want to buy a used logic board, you'll need to install it yourself, or perhaps an Apple Authorized Service Provider would be willing to do the work.

Checking RAM upgrade options

Okay, I want to confirm what type of RAM and how much the system can handle as different websites seem to have different information. Here's the information:
Macbook 2.1, 2.16GHz Intel Core 2 Duo 2GB 667MHz DDR2 SDRAM
Serial #: W87280CRYA9
2 DIMM slots
I would like to upgrade to 4GB, and from what I've found I need:
PC2-5300 DDR2 667 MHz Type RAM.
I would really appreciate confirmation that this is correct before I move forward with purchasing. Thank you.

what I've found differs though about the amount of ram that this machine can handle. one mac store said it can only hold 3GB of RAM, while another says 4GB.

RAM slot broken / plastic tabs on RAM slot broke off

I was a little rough when I installed my RAM and broke the plastic tabs/locking mechanism on my RAM slot. A RAM card can still fit in the slot but it just doesn't lock in. I'm considering these options:
1) keeping the RAM in position with a tiny piece of electrical (or other heat resistant) tape. And I could check on it every few days to see if it melts or anything.
2) having a technician go into the inaccessible RAM slot and just upgrade that. Is that possible? How much would something like that cost?
or
3) installing a new logic board, which is what one MAC store diagnosed for me. But that would cost $575 (part) + $100 (labor) which I'm very reluctant about because that is way too much money for me.
If the tape method seems worth a try, I'd love to do that since it's the easiest and cheapest. Any advice would be great. Thanks so much.
Amy

I broke the tabs by removing the ram chip after trying to force it. In the set up guide that came with the computer the instructions failed to mention that the clips should be in the open position before installing. I bought some "cold Weld" like a two part epoxy and glued the composite clips right to the stainless steel "wing" of the clip. It seemed to work just fine. the chip clipped in place but system profiler does not recognize it at all.

DIMM 3 and DIMM 4 RAM slots won't work

Good evening,
I bought an Z77A-G43 board, together with an i5 3570K and 2x4GB ADATA-1600 RAM. When I first started my new system, it didn't boot. The fans start spinning, than the system shuts down after a few seconds, without showing anything on the screen nor beeping. I figured this only occurs when DIMM 3 or DIMM 4 are used. (For Dual-Channel I have to use them.) What I tried to resolve the issue:
- Reseated CPU
- Disconnected all peripherals (HDD, ..)
- Successfully flashed the BIOS to version 2.8
The board recognized my RAM as 1333 and 1.65v, while it is labeled as 1600 with 1.5v. I tried:
- Manually trying all combinations (1600+1.65v, 1600+1.5v, ..)
- Activating "Extreme Memory Performance", which now detects my RAM properly on "auto" (1600+1.5v)
All this did not change the fact that my system doesn't boot when using the third or fourth RAM slot. (Which are shown in BIOS as first and second by the way, if that is to any relevance.)
Is there anything I can still try? Or do I have to send the board back? :(

Remove CPU and check the MB CPU socket for bent/damaged pins (good lighting and magnifying glass is needed). That is primary cause of problems with slots 3 & 4 RAM on s1155 MBs. Memory controller is in CPU and there have been some people that have had bent pins in the socket being the problem. Usually they can be straightened out with not much trouble.
Here are a couple of examples:

MSI-7125 K8N neo4f ram slots not working

I have had this motherboard for a little over a year and a few days ago I was on the internet got up for a minute came back and the display was black, I reset the computer and it wouldn't come back on so I disconnected the power cable opened the case and started looking around and couldn't see any physical problems with the board so I took the Video card out, then the ram disconnected the hard drives and optical drives I cleared the CMOS by taking out the battery and leaving it disconnected for 20 minutes,after that time I reinstalled all the components and pushed the power button you could hear it botting up the hard drives and optical drives all the fans were running but no display, So I thought to myself check the ram I started trying different ram slots and there it is the only slot that would work with a single stick of ram was slot #2(purple) and the only slots that would work for 2 sticks were both of the purple slots, I had read the manual and this was very strange considering it say's not to install ram into the purple slots while the green ones were not in use, I am not sure why this just started with no warning I have always use the first 2 slots since I purchased this and never had a problem with this motherboard except for my North bridge fan starting to slow down I replaced it before it quit working other than that I haven't done anything else to it. I would extremely appreciate it if someone could help me out with this problem sorry for such a long post.
THOMAS

Well I've been working on computer's professionally(for place I worked) and privately tried supplemented my income for a while, and most of the problems I seen was either memory related or OS related, I know it wasn't my OS been running fine for a month or so after re-format and just figured it had to be ram related and started checking it out and I was correct . Although I never seen this problem before and that it is aggravating( I just received an email from MSI) and it said I was at the end of my 3 year warranty and that it will cost me $45 bux for them to check it out. I just bought this last year dont see how that is possible. I guess I'll try to redo BIOS to 5.2 and see what happens.

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.
