Problems after RAM upgrade

I just installed 2 * 1Gig Kingmax DDR400 (PC 3200) into my imac. Replacing the 2 * 512Mb sticks that were installed when it shipped.
Since installing (about 3 hours ago) i have had 5 programs quit while not being used (activity monitor counting for 3 of those)
Then, the system froze and the fan started going crazy. ive never heard it spin that fast since i bought the system. I couldn't even get the mouse to move. Once i shut the system down (holding the power button down) and rebooted the system has run fine, though its only been 10 minutes.
Is it the ram? should i be taking it back? from what i have found the kingmax ram should be fine for my imac.
any thoughts?

I will try that now. Thanks.
I have tried the test that comes on the install CD, and after an hour or so it came back as everything being Okay.
I have had the system crash about once every week. So I have decided that the time it is saving me is worth the reboot time. :/ Dosent look good when people are around tho. (But i manage, quite successfully IMHO, to blame KingMax).
I will report back soon.

Display problem after RAM Upgrade to MS6712

Hi there,
after a RAM upgrade (512mb to 3GB) my PC has developed a display problem. The graphics are slow / rippled and video playback is very poor. In device manager no "display adapters" are present and there is also an error mesage referring to the VIA CPU to AGP2/AGP3.0 controller not having enough free resources to run due to a conflisct with VGAsave? I've downloaded the latest VIA chipset drivers to no effect?
System info: MS6712 MB, AMD Athlon 1.25GHZ, XP SP3.0

OK, here's the info on my PSU;
It's a Powerman FSP250-60GTU(PF). Input: 230V - 5A, 50Hz. Max Output: 250W
While I had the case open I took out 2 of the RAM modules and without making any other changes everything appeared to work fine with just the 1GB, so I tried putting 1 more back in to take it to 2GB and again all seems fine? Does this indeed point to my PSU then? If so and it works fine with 2GB should I be thankfull for a 512mb to 2GB upgrade and send the 3rd module back to Crucial??
Before I posted this thread I did run a memtest from Memtest86+ with all three modules installed and it came up with NO problems?
Re Henry's post, I searched using the format of the part no on the RAM modules themselves i.e. M368L2923FLN-CB3 and it took me here:
http://www.samsung.com/global/business/semiconductor/productListNonflexTable.do?fmly_id=118&sht_id=1
Other info on printed the modules themselves: 1GB DDR PC2700 CL2.5
According to Everest my CPU temp (with 2GB installed) is: 43 degrees (MOBO 30 degrees and HD 42 degrees) - do these seem normal?

Video problems after RAM upgrade

I recently upgraded my ram from 1GB to 2GB DDR2 667 MHz and everything looks fine with regards to recognizing the RAM and starting up. However, I recently started to notice some video problems in certain areas. For example, my VLC player has problems playing back video now, and it shows a black screen for the video for some avi files but plays back the audio fine. Some games, like Plants vs Zombies, play audio and not the video as well. Has anyone else had this problem?

Don't know anything about 4AllMemory. But they do indeed have a small Mac section listed. Hard to tell if the memory listed is specifically for your model. Also not obvious if they have lifetime warrantees too.
As for OWC's page. Yes, that 4GB selection, which if you clicked on it would take you here, is memory that will work on your 3,1. The only real difference between it and the one listed below it for a few dollars more is that the latency of the ram. You probably woudn't even notice the difference (cas 4 vs. cas 5).

K7 Delta 2 Nforce2 boot problem after ram upgrade

Ill start out with the stats of the system
Delta 2 w/ DDR-400 Ultra support
Althlon XP 2100+ 266fsb cpu
512 Mb Mushkin High Perf Level II 2-2-2 Ram
80 GB IBM Deskstar HD 7200RPM
30 GB Maxtor HD 7200RPM
Radeon 9700 Pro
SB Live 5.1 Soundcard
Standard 400W power supply, all voltages were normal
So here is the issue, this system was running perfectly until i purchased two more sticks of mushkin ram, 2x256 mb ram sticks of Hi Perf Level II 2-2-2 ram, i placed this in the dual channled slots. Machine then restarted and i got into BIOS where i set the clock to 166 to obtain my 333 fsb for the RAM, and selected the high performance timings. This is when disaster happened, upon saving to cmos, nothing will work now, no bios screen, no beep errors, just the two green lights on bottom, and red lights on top of the MSI s bracket. I have swapped out the ram, and cleared the CMOS, same thing, im all out of ideas, im going to try swapping the CPUs, but how could there be anything wrong with the CPU, i know all this stuff worked on the system. Any Ideas?

First Refer to your manual to make sure I have this right as I am going from memory.
As Wonkonoby suggests, the J10 jumper can be set to safe mode 100mhz for the CPU FSB.
Then remove the jumper block from J11, this will set the CPU Frequency to 100mhz.
These settings will usually help in recovering from bad settings in the BIOS or an overclock gone awry.
You may have to Clear the CMOS with JBAT1 Jumper, but please make sure you DO NOT start your PC with the JBAT1 jumper in the clear CMOS postition! You will probably bork your motherboard!
To clarify:
Please unplug the power supply from the power outlet or remove the power plug from the back of the unit.
Then, press the power button to purge any remaining power that is in the capacitors in the power supply. (sometimes you will notice the fans spin for a millisecond when you do this)
Set Jumpers J10 & 11 as described.
Clear CMOS by moving the JBAT1 Jumper to the "CLEAR" CMOS position for a few minutes. (it's often recommended to remove the battery after moving the jumper to the "CLEAR" position and waiting a few minutes befor replacing it and then replacing the battery and moving the Jumper back to the "KEEP" position)
Thats it, you should be able to start your PC and enter the BIOS. Make sure you set the jumpers J10 and J11 back to where they were and then enter all your BIOS settings again but this time be careful about timings.
If that does not work then you have a more serious problem.

Any ideas?

Hi,
Just to help the folks out here.
In my case,
Inspite of going through several valid NOTES & program, my issue didnt resolve (you reply was pretty accurate - but dint help me :-)).
I have resolved the issue by adjusting the PSA table for the same.
Procedure:
Take the psa name --> go to table rstsods --> find the ODSNAME_TECH name for the relevant psa --> se38 t.code --> enter ODSNAME_TECH and click on 'adjust & activate database table' (make sure you have selected 'save data' radio button.
Just in case anyone who come across this problem, can do the above steps.
Regards,
Dubbu.

I installed iOS 5.0.1 on my Iphone 3GS. I never can not write in my calendar. Anyone else having this problem after their upgrade?

I installed iOS 5.0.1 on my Iphone 3GS. I never can not write in my calendar. Anyone else having this problem after their upgrade?

I was going to suggest - Settings>General>Reset>Reset all settings, but if you are restoring to factory settings, that should restore the settings back to factory defaults. But if you are restoring from a backup, after restoring to factory settings, try resetting all of the settings and see if that fixes it.
It might be something in your backup.

I have a mac, would like to upgrade to mountain lion from mac os x, anybody experienced any problems after this upgrade, thanks

i have a mac, would like to upgrade to mountain lion from mac os x, anybody experienced any problems after this upgrade, thanks

Check that your computer is compatible with Mountain Lion.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
iMac (Mid 2007 or newer) model number 7,1 or higher
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
MacBook Air (Late 2008 or newer) model number 2,1 or higher
Mac mini (Early 2009 or newer) model number 3,1 or higher
Mac Pro (Early 2008 or newer) model number 3,1 or higher
Xserve (Early 2009) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again. You can make a bootable DVD/USB stick to install using this free program.
Bootable Drive DVD or USB Flash Drive – Lion Diskmaker
Our 2 computers haven't experienced any significant problems, even though others have. I find it much better than 10.7 Lion, which I used for a week before reverting to 10.6.8
Mavericks is supposed to be released this fall, so you may want to wait.

Boot problem 10.4.11 after RAM upgrade of PowerPC G3

My PowerPC G3 won't boot. Not sure what to try next.
I tried to replace my RAM with four 256mb sticks. Previously I had four 128mb sticks of PC100. At some point in the install I received the error of a grey screen that stated (in several languages) I needed to press the start button? My power button would not shut down the computer. I wind up with a blue screen and the mouse cursor.Since then, the OS will not load. At start up, I get the Grey Apple with the twirley status icon for several minutes; then a blue screen with the twirley for several minutes. Then just the blue screen, with my mouse cursor.

The gray screen in several languages indicates you had a kernel panic. Kernel panics are usually caused by a hardware problem – frequently RAM, a USB device or a Firewire device. When trying to troubleshoot problems, disconnect all external devices except your monitor, kbd & mouse. Do you experience the same problems?
I suspect you may have some bad RAM. Where did you get the RAM? Have you tried reinstalling the old RAM? Some recommend that you do a CUDA reset when you install new RAM. Another thing to try is to install just one 256MB module. If that doesn't work, remove & install a second module.
 Cheers, Tom

Video will not play on Canvas or NTSC after RAM upgrade

editing on a G5 v. 10.4.11, Dual 1.8 Ghz G5 with a recent upgrade to 4GB of ram. Have an AJA IO LA
After the RAM upgrade, FCP timeline will play but video is black in the canvas and image is frozen on the NTSC. Video WILL play in Viewer but no audio.
All cables have been checked to make sure they were put back correctly - will keep checking for errors in re-cabling computer.
Have tried refreshing displays and other tests with displays. Any info would be greatly appreciated.
Thanks!

pull the ram, problem goes away? - bad ram
you can pull 2 sticks at a time to isolate which chip it is.
did you get it from a good source - Crucial.com is my favorite, OWC is popular too - both have lifetime warranty

Mac mini won't boot after RAM upgrade.

Tried installing new RAM in my Mac Mini, 512MB stock to 2GB of Crucial. Followed the directions to a T, grounded myself the whole time.
Things I've tried so far:
1. Resetting the PRAM, no luck.
2. Holding option at start-up, shows no icon.
3. Holding shift, no luck.
4. Holding X, nothing.
How do I get it to accept a CD if it won't boot?

Welcome to Apple Discussions!
You clearly have a problem, but you don't describe exactly what that is other than that your mini won't boot after the upgrade. What happens when it starts up? Does it attempt to start and hang up on the grey or blue screens, or does it start beeping at you almost immediately after you try and start it up, and also flash the power light?
If the former, then you may have dislodged a connector while working inside the system, in which case opening it up and checking that everything is firmly connected would be the first thing to do. If the latter, then the beeping/light flashing is the system telling you it has failed the power-on self test and the pattern of beeps/lights indicates why. In your case likely the system can't find workable memory. In that instance, opening the system and ensuring that the RAM is firmly and fully seated would be a good step, and if the mini continues to fail, then replacing the new RAM with the original to test that the system will then start.
It is not likely that anything had damaged your MacOS install in the process of upgrading, thus normally no reason to need to boot to CD as a result of a RAM issue.

MacBook not booting after RAM upgrade

I'm sorry if the case has been already posted.
Yesterday I took my MacBook Alu unibody late 2008 to a RAM upgrade (from 2 to 4gigs) to an offical Mac Reseller. They installed it and showed me that the system loads properly and recognized the new RAM.
I took it home, started working on After Effects and Photoshop and when i wanted to check a video on Quicktime, this program refused to boot.
Then photoshop freeze and after effects did so. I quited all aplications and restarted. On restart after the 'bong' i've got the grey screen white an apple logo and a loading bar underneath, that was it, it never finished loading but shutting down.
After the 2nd try the computer gave me the BAD RAM alarm signal right before the start button was pressed and nothing more. I just managed to start it ONCE on safe mode, but this one also freezed and colapsed.
Today i didn't get the BAD ram alarm but the grey screen and loading bar after shutting down.
I took it back to the reseler, the shop boss who did the upgrade wasn't there , the guys on the morning shift placed the old RAM back resulting the same. So they told me it's a software problem, not hardware and might be caused by a failed firmware update or something i did wrong and since i was showed that the system booted after the upgrade i can't complain or argue that they did somethiing wrong.
So basically the want 80euros to check what's wrong with my computer plus the 120 i already payed them for a RAM that doesn't work and of course the repair cost of the computer.
On monday i'll go to talk to the boss, what do you guys recomend me to tell him? i'm frustrated that the guys there treat me like if i broke my computer for beeing stupid and wanted to get it fixed for free, when it clearly broke after they did something wrong on it!
please advice me!
thanks!

What brand is the RAM? From what you said, it is obvious that the RAM is at fault. I would simply tell them that it is not compatible and return the RAM.
Check the System Profiler to see what it says about the RAM (Apple Logo - About this Mac - More Info) and run this application to test the RAM:

If either shows any errors, print out the results and take them with you to the store.

Problems with RAM upgrade iMac G5 1.8GHz

Stuck - Need Help!
I've previously upgraded up iMac to 2 500Mb RAMs and felt recently that it needed that little bit extra, so I ordered two 1Gb chips from crucial.
Followed instructions to T, but with the two new chips in, the machine won't load.
Interestingly, it boots up with the following RAM combinations
old 500MB + new 1GB (in any combination) - recognised as 1.5GB
one new 1GB RAM (again either one) - recognised as 1GB
I spoke to crucial who said that as the RAMs work individually, there isn't a problem with them, it could be a Firmware issue. I've upgraded all my software, and don't know what to do next?
Anyone overcome a similar problem in the past?
Thanks

I'm experiencing something very similar to shaow. I'll share my experience in gory details - sorry for the long post but I've spent more hours trying to stabilize. I should have worked the hours at walmart and bought a new iMac with the money I could have earned
Anyway, here goes:
Two iMac G5 1.8Ghz 17" (both Fall 2005 model), will call one A and the other B.
Prior to attempting ram upgrade: A, config working fine: both a config using 1GB slot 1, 256MB slot 2 and a single 1 PC3200 1GB stick. OS X 10.4-10.5.7. No problems. I did have the motherboard replaced under warranty after having sleep problems - capacitors were expanded. No problems since that motherboard swap.
Prior to attempting ram upgrade: B, config working fine: 2 x 256MB sticks. OS X 10.3.9
Ordered 3 PC3200 400Mhz 1GB sticks from Data Memory Systems.
Upgraded A: Added 1GB stick = 2GB total
Upgraded B: Removed both 256MB sticks from B and added two 1GB sticks = 2GB total
Booted B, experienced gray screen of death with the multi-language crash message - somethign like: 'Please hold down the power button and restart'. Power cycled B, booted off a retail box DVD of OS X 10.5.6. Began upgrade to 10.5.6. Gray screen of death part way thru upgrade. Power cycled, gray screen of death again during early boot phase.
Decided to run tests on B. I could not locate the Apple Hardware Test (neither on system dvd 1 nor on a separate DVD). I resorted to using TechnoTools Deluxe which was included with AppleCare box. No hardware problems found including on the 2GB memory.
Removed both new 1GB sticks, pulled older working 1GB stick from A and installed into B. Completed upgrade with just 1GB memory on B to 10.5.6 and subsequently pulled down all updates for OS X 10.5.8. Powered down, added second 1GB stick to B, booted into 10.5.8 successfully. Repaired disk permissions, restarted. Began using applications, then after only about 5 minutes experienced gray screen of death. Powered down, removed new 1GB stick, replaced with one of the two remaining new 1GB sticks. Read about reseting PRAM/NVRAM. Followed steps to reset PRAM then decided to do the reset NVRAM within openfirmware. Started back up and logged into 10.5.8. Ran several applications - did not experience gray screen of death after about 20 minutes use. Have not had time for further tests on B yet.
Back to my saga with A (my original iMac G5 that was working fine with 1GB stick on 10.5.7):
Called Data Memory Systems and they sent me a replacement for the 'bad' 1GB stick.
While I was waiting for the new 1GB stick from DMS, I was struggling to get machine fully updated. Software Updater was failing with the weird network error (network was fine) and after following steps to troubleshoot, I backed up the user accounts and decided to reinstall OS X fresh from the 10.5.6 retail box (family license). Finally, I had OS X 10.5.8 all fully updated on the 1GB iMac G5 (A).
New memory arrived, installed 2nd 1GB stick. Booted up, immediately I got the gray screen of death. Restarted, booted up got about 5-15 minutes use then gray screen of death. Puzzled, I called DMS who said unlikely I got 2 bad sticks. They suggested I try memtest. So I did...
So on A, I first ran memtest from single user mode on the 2GB config. It crashed immediately with some 'Unexpected' error. Did not look like a memory error. I powered down, removed 2nd 1GB stick, and ran memtest from single user on the 1GB stick. Ran all tests 3x over a couple hours - no problems found. Retested after swapping the 1GB stick for the other. Both tested fine. Installed both sticks again and ran memtest all tests, one pass (didn't want another 6 hours lost) on the 2GB config, and all tests passed. Booted up and got gray screen of death - I don't recall if it was on bootup or after running but I ran fsck with no disk problems found, then restarted, logged in, ran disk utility to repair all permissions. Some repairs were made. Restarted A, reset PRAM and NVRAM again, booted successfully.
I haven't had much time to run extensively apps on A yet. It's sleeping as I type this on another mac. My next test will be to reset SMU.
I'm starting to wonder if the original iMac G5 has firmware problems that would prevent it from being unstable with two 1GB sticks??? My experience on two identical models of iMac G5 plus reading this post with VERY similar behaviors and after all the normal tests. I've concluded the memory is A-OK and something more sinister is lurking...
Any thoughts are appreciated.

Lenovov S960 / Vibe X LED Notification Problem after Official Upgrade to Kitkat

hello Lenovo,
after i updated my phone to kitkat i found so many problems (bugs). like the contact manager crashes, no name in incoming call and the LED notification. before i updated my phone to kitkat the LED notification always blink when i recieved emails, messages, missed calls, bbm, whatsapp, and line.
but now with kitkat running my phone, the LED notifciation doesn't blink anymore everytime i recieved notifications. i already turned on the LED notification in phone settings and apps setting. am i the only one who's facing this problem or there is anybody else that facing the same problem?
please help me anybody how to solve this problem?
and i have one more question. how to keep apps running on background? apps like bbm, line and whatsapp are closed everytime i clean up the ram and never come back on again until i open the apps again. and again i face this problem after i updated my phone to kitkat.
any kind of help is very appreciated.
my build number is S960_ROW_S210_140529

Hi, I found there are other issue apart from contact manager crash issue after upgrade from Jelly bean to KitKat 1. in the same way google chrome is also crashing after trying to open gmail and start enetering username2. caller name is not displaying while getting incoming or outgoing calls3. I found some suggestion in the same community website that first take a backup, delete all the contacts, and them import it back to solve the issue. But why we need to do these, why this issue is happening after upgrade4. however I deleted contacts and tried export from the storage. While doing so, Contacts->Menu->Import/Export contacts->Import from storage, it finds and displays all the .vcf files. Very good, but there is no select button to 'select all' the vcf file to import to the address book. I don't want to sit and select each .vcf file from the list to import it as there hundreds of contacts. I think 'select all' option is missing after upgrade. I heard, in kitkat version some performance issue is fixed but now it seems to be many basic functionality features are not working after upgrading. We are all waiting for your response and good kitkat upgrade notification in our mobile. Thanks,Sharath

OT: Dreamweaver quits after ram upgrade

Anyone had this senario before. I upgraded ram from 1gb to
2gb and now
MX04 just keeps quiting on start up, lol.
I haven't done a complete reinstall of the software yet but
any ideas
why this should be happening?
All other software, Photoshop, Illustrator, Quark, InDesign
appear at
the moment to be uneffected.
Iz a weird, weird world.
Humm I was intending to upgrade to CS4 but I'm awaiting the
trial
version first.
Oh well I guess I go back to other computer for the moment.

Hi Alan I have the issue with MX04 so I don't think below
applies,
according to this line:
'The crashes do not occur in Dreamweaver 8 or earlier (Ref.
229536).'
Problem just started after I upgraded the ram from 1gb to
2gb, which
seems odd, but hey I expect anything these days. Some file
within DW I
think may have been affected by the time/date because on
reboot I had a
warning that the computers clock/date was set to March 2001
and may
interfere with some software, even weirder as I only
purchased the
computer last year, so why the clock should go back to 2001 I
don't know.
I'll try a complete reinstall and see if that clears it up,
overwrite
the corrupt file hopefully. It doesn't matter much to be
honest I was on
the verge of upgrading so I can live with it for now.
Thanks for your input.

KT3v MS6712 System Won't power up after RAM upgrade

hello this is my first posting to this forum and I hope someone might be able to help on this as I am totally stumped. I have been running my KT3V MS6712 mobo with 256MB since it was built. The manual for this mobo says it can handle up to 3GB RAM in any order or size. I have 3 DIMM slots and thought it would be more cost effective to just
purchase 1 DIMM leaving the other 2 slots free. So I decided to upgrade to 1GB and I bought a Kingston 1Gb PC2100 266MHz DIMM and installed it on my system. Now my system won't power on at all. When I press the power button on the PC, the CPU fan spins for like 1-2 seconds then stops. The system appears to be completely dead. Cos I thought the problem was down to the new RAM installation I thought better put my old 256 DIMM back, however I still get the same problem. I have tried swopping both DIMMS into different slots but still doesn't work. The system was working fine until I did the RAM upgrade. I tried resetting the CMOS by moving the jumpers around in case it was a BIOS issue, still hasn't made a difference. Dunno if its the PSU which has suddenly gone, however seems strange. There are no beeps from the system or lights flashing to indicate anything. I don't have
the D-Bracket installed either. I have also never upgraded the BIOS on this system as it has always been stable. The CPU is not overclocked. Has anyone had this problem before after a RAM upgrade? Hope I have given you enough information

Suntek is perhaps not the best of PSU makers, but a sudden collapse is not so common. You normally notice problems earlier.
I took a big beating last time I said this , but it is important that there is no power in the system when changing memory sticks.
It sounds a bit like the processor went away for holiday. Have you any data on the processor temperature? Is there any activity at all? Does the processor heat sink get warm?
