Using RAM slots 3&4 (vice 1&2) on a Neo2 Platinum

I was having some issues that seemed RAM related so I ran Memtest and it showed one stick with lot of errors, but the other seemed fine. I only ran it on each stick for a short time because I got 34 errors in 20 seconds on one stick, but the other was error free for about 10 minutes.
I pulled the bad stick (temporarilly running 1x512) and everything was fine for one day, but I just got another memory dump BSOD. Now this stick shows errors.
I'm curious if maybe Dimm1 on my board could be eating my RAM. I've already got 2x1GB sticks on the way. Should I just put them in slots 3&4 and not worry about slot 1, or am I asking for more problems that way? Also, has anyone heard of Neo2 Platinums's destroying RAM?
Complete specs in sig.

You can run two dimms in slots 3 & 4 as an alternative to slots 1 & 2 according to Jim Flynn who seems to know what he is talking about here: https://forum-en.msi.com/index.php?topic=88800.0
Do you get errors in MEMTEST with slots 3 & 4?
The errors in memtest require some troubleshooting with the assistance of CPU-Z which will tell us the SPD and actual operating timing values of memory (cas, tras etc) for each slot on the SPD and MEMORY tabs. What voltage are you using for your dimms? Are you overclocking?
You might not want to insert your new memory until you figure out what is going on with your slots, as I imagine a faulty slot (and maybe faulty configuration too) could damage memory.
Post CPU-Z and MEMTEST results for slots 3 & 4 and maybe one of the memory gurus here will lend a hand. I believe errors in tests 5 & 7 are timing errors while the rest are bad ram.
Good luck.

Gaming 5 ram slots not working

Hi
I gave just upgraded my mobo and cpu to z97 gaming 5 and i5 4690k. The issue I have is when I use ram slots 3 or 4 the system with not boot and the error code 03 will be displayed. Slot 1 and 2 are working its just when I try and use slots 3 and 4.
As per instruction I should be using slots 2 and 4 but cant.
Any Ideas. Current ram is a data 2 x 2gb

Hi I have tried both individually in each slot, as soon as I use 3 or 4 PC doesn't post. The debug error 03 is displayed on the mobo. No I don't have other ram to try. As I say it works I. 1 and 2 .

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:

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:

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.

17" iMac (1.6Ghz PPC) can use Ram with Heat Spreader?

Hello There Apple Community,
i have a vintage 17" PPC iMac, it support 2GB of max ram., here in my country those memories are hard to find, the ones i found, there are DDR 1GB 400Mhz which is the right one, BUT they have "Heat Spreader" can i use them to upgrade my iMac?
Cheers....

Hello Juan Bermudez,
While it is not explicitly stated that memory with heat-sinks will not fit, I do not believe that they will. The following document provides the specific requirements that your iMac G5 has with regards to memory.
About iMac G5 Memory
1. iMac G5 computers work with memory modules (DIMMs) that meet all of
     these criteria: PC3200, 2.5V, unbuffered, 8-byte, nonparity, 184-pin,
     400Mhz DDR SDRAM.
2. There are two RAM slots. The maximum amount of RAM you can install is 2
     GB. You can use RAM module sizes of 256 MB, 512 MB and 1 GB, in either
     slot.
3. DIMMs with any of the following features are not supported in the iMac G5
     computer: registers or buffers, PLLs, ECC, parity, or EDO RAM.

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.

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

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...

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.

Upgrade Early 2008 from 10.5.8, to ? PLUS a broken RAM slot

I have a Early 2008 white MacBook, 2.4 GHz Core 2 Duo.
As I understand it, if I want to upgrade to 10.7, I need to first purchase a 10.6 DVD, correct?
Is a multi license DVD available? I have 2 machines running 10.5.8, the MacBook and an iMac.
Also, the MacBook has been dropped, and now only 1 of the 2 RAM slots works. (I think the Logic Board is damaged)
It looks like it could normally support 6GB (4+2), but since I can only use 1 slot, can I use a single 4GB, or just a 2? (It currently only has 1GB)
I realize I should probably just buy a newer machine, but honestly this one does all I need. The only reason I am even updating the OS is because Firefox will no longer work, and some other similar things that are software related.
Thanks!

With the Snow Leopard OS X 10.6 retail DVD, the license is usually for one computer at a time to be using the installed system. However as soon as each computer is upgraded to 10.6.8 and running adequately, any computers fated to access the App Store or Mac App Store for OS X upgrade to 10.7.5, would no longer be running Snow Leopard 10.6; so the license would be open for another upgrade at least to 10.6.8.
The ailing Mac with only one RAM slot should probably not be upgraded to a higher OS X than 10.6.8, in fact you'd likely need all the supported RAM an undamaged computer would normally have in a full upgrade, for a later OS X to work adequately. Given the damaged machine is running on borrowed time, and needs a hardware repair (such as a specialist authorized Apple repair service can do, in or out of warranty) the least effort involved would be better.
The older iLife and other applications that ran OK in Leopard 10.5.8 & earlier won't do so well after Snow Leopard 10.6.8 because a feature is not available after 10.6.8 by the name Rosetta to run older powerPC based applications that were common. Those will not run in later 10.7+ or without Rosetta installed from the Install disc in 10.6.8. This may add a layer of difficulty if you have application installers from another era.
There are a few fairly good highly capable portable Mac repairer service companies that could fix the issue in the partially failed MacBook for reasonable cost, and inspect the rest of the computer, before offering a warranty on their own work. Some of these also offer repaired models as part of their overall business. One that I have brief familiarity with some 8 or 9 years ago, was wegenermedia.com & sent an iBook to them in the mail. And recently discussed with them a repair to my first-edition MacBook 1.83GHz coreduo.
With only one RAM slot working you could try either chip, to see if one works better than another; however the way core 2 duo processors use RAM it is better if each slot has similar RAM, since it may affect processing as well as data flow. Later models really prefer matching spec sets.
Have you looked into the iFixit manuals to see the effort involved (if they show it) behind getting to the logic board? Some aspects of repair can lead to more damages than the cure was meant to fix.
Hopefully it will work OK.
Good luck & happy computing!

15-F018ca upgrade/ram slots

I want to upgrade the ram. I've tried to replace the only user accessible ram module under the laptop by a same spec 8gb module (but from Crucial) and it refuse to boot. Tried with a few other DDR3 and DDR3L (4gb and 2gb) but the only one that work and boot the laptop is the original one (samsung 4gb-pc3-12800).
Two questions: In the user manual and on vendor website they all list as two user accessible ram slot. In the bios/boot/utility tool it mentionned that slot/2 is empty. So where is it ? (have to disassemble the laptop to access it?)
And what memory is known to be a good compatibility for this serie of laptop ? (if a second slot is available 4gb+4gb configuration will suffice but if not what 8gb module is compatible?)
This question was solved.

Hi,
The manula clearly says on page #1:
Two SODIMM non-customer-accessible/upgradable memory module slots (Core i3 processors)
DDR3L-1600-MHz dual channel support (DDR3L-1600 dual channel support)
One SODIMM non-customer-accessible/upgradable memory module slot (Pentium, Celeron processors)
DDR3L-1333-MHz dual channel support (DDR3L-1600 downgraded to DDR3L-1333)
DDR3L-1066-MHz dual channel support (DDR3L-1600 downgraded to DDR3L-1066)
Supports up to 4 GB max system memory (DDR3L-1600MHz module)
Supports the following system RAM configurations:
● 4096 MB (4096 MB×1 or 2048 MB×2)
● 2048 MB (2048 MB×1)
Your machine uses "2.16GHz Intel Celeron N2840 Processor with Turbo Boost Technology up to 2.58GHz" that means only one slot and already max 4Gb that whay it says non-customer-accessible/upgradable memory

Lenovo G580 2nd Ram slot broken

My laptop was preinstalled with 4gb and recently I brought a new 4gb ram to add to the computer but as I inserted it in the 2nd slot it still detects it as 4gb. I tried numerous times and also tried swapping them to find out and I know it isn't the new ram because Windows detects it on 1st slot but it's only when I put a ram in the 2nd slot that it has errors. My Windows is 64 bit so it should be able to use more memory. I don't know whether it could be the snap-in or something is wrong with the memory in the hardware. Could I get this fixed from a store or some remedy to get it to read?

Nevermind everyone. I feel so stupid right now. Turns out after hours of messing around with the ram slot I forgot that I needed to actually push down the ram into the slot rather than just inserting into place. I solved the problem myself so it turns out it wasn't a bad slot after all.

? RAM slot problems (and much, much more... :))

Have a brand new 'Intel' iMac 20", and installed RAM (from Crucial memory)into it.
Twice now I have had a major crash. First time it got sorted by re-seating the RAM, but now it's happened again. I think one of the two RAM chips may be faulty, but intermittently, which is a pain.
Can I ask the following to help me along:
1) Is it a known issue that there may be faulty RAM slots in the iMacs?
2) I may have to run MemTest on my system, which recommends starting in single-user mode to do a full RAM test. Can I start in single mode with a WIRELESS keyboard (according ao the Apple site you can with OS 10.4.8 - the bluetooth 'drivers' must be buried well deep if this is so!)
3) Read somewhere that resetting PRAM and NVRAM should be done after all RAM additions/alterations, but elsewhere that this is an evil falsehood. Which is true? And if recommended, again can I do this with a wireless keyboard.
4) Of course if your RAM is faulty your machine may not start up at all so HOW CAN YOU DO ANY OF THIS!!!??
(Thanks!)

1. No, there are no known issues with RAM slots in any Macs. However, if you were not careful to follow instructions on seating the new RAM you can damage a slot, although this is unlikely.
2. You don't need to use MemTest. Boot the computer with the OS X Installer Disc One that came with the computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended diagnostics. If there are any memory or hardware problems they should be detected.
3. I've never reset the NVRAM (PRAM) after installing new RAM, and I've never had a problem. That said resetting the PRAM/NVRAM doesn't hurt anything.
4. Start by removing the new RAM you installed and use only the original RAM that came with the computer. If the computer works properly, then it's reasonable to assume the new RAM is faulty.
Be sure the new RAM you purchase meets the required specs as outlined in your User Guide. The RAM must be PC2-5300 667 Mhz DDR2.

Great design effort RAM slot KT-6 delta

I congratulate the MSI designers for their RAM DIMM slot electrotechnical design.
it works nicely foolproof. my RAM slot was visibly obstructed so I inserted a DIMM in wrong position. Yet my 6590 survived as did my RAM module.
Only the slot burned off, but thats no problem, since only 2 of those original 3 slots can
be used for FSB 400 memory anyway !
this is what university people call "gracefully degrading systems"
MSI designers keep going like this !!
greetings from europe !!

MSI is the top five motherboard manufacturer in the world so it is obviously that they are good
