PM8PM-V memory upgrade problem.

Hi,
Hope somebody has an answer.
I have a PM8PM-V motherboard that I am trying to upgrade memory for.
I checked the website and got the following 2 x Kingston KVR533D2N4/1G pieces.
I installed both and immediately got error beeps.
I removed 1 still error beeps.
I replaced one of the old pieces (DDR2 667) and it worked.
Thought maybe bios upgrade went from 3.0 to 3.3.
Still error beeps.
I have rechecked both Kingston & MSI support documents and this memory should work.
Help!
Thanks,
Nic

Weird behaviour.
I waited for 2 full cycles of error beeps then depressed the reset button.
PC then came up!
Maybe something to do with memory configuration change in bios?
In system only registered as 512MB and not 1GB!

Memory upgrade problems on Satellite L30-134

I have just bought 2 x 1GB memory PC4200 for my L30-134 and installed them they work fine in BIOS, show up and read as they should do, but when windows is booting up it will crash with both modules installed, only ever gets to the screen with the loading bar going across and then I get blue screen.
Forgot to make a note of the error code I am afraid... (Fool I know). If I remove one of the modules and install the original 512 module with just 1 of the 1GB ones it will work fine. BIOS has been updated to the latest 3.10 version and still I get the same problem...
because all seems fine from within BIOS I am thinking that its more likely to be a software (windows) problem of some kind maybe some corrupt data in the registry or a virus maybe... has anybody any ideas?
Also, the laptop is actually my step sons and he really wants to have the CPU upgraded from the Celeron 410 to one that's a little faster. When first looking into this we was told that several CPUs were compatible (although not really worth the hassle of installing) they were cel m 450 2 GHz, pent dual core t2060 and t2080, and also the core duo t2250,so he bought the t2250,and no surprises it wouldn't work, or should I say it powered up with no display and the shut off and just epeated the cycle. So did not take a genius to work out it wasn't compat...
I know the t2080 are used in the L30's and are 1.73 533 FSB with 1MB L2 cache- 65nm and do stepping. The t2250 is identical apart from the L2 cache is 2MB and the stepping varies from do to mo depends when u bought it... seeing as ow he already has the CPU he's gonna sell it on and use the cash to buy the one that will work. If anybody has any info that could help make sure that he does not end up going round in circles I would really appreciate it...
Oh and just to make you all laugh it was Toshiba tech line staff member that told him that the CPU would work and that the L30 was able to take 2 x 1GB memory and never once mentioned that there may be issues with both upgrades...
Issues as in neither soddin work....lmao

Hi!
The specs. you posted are correct. Xpress 200 could support dual channel: "Variants available with single or dual channel system memory support ". But there is nothing about dual channel mode in Xpress 200M specs. I have identical modules, but EVEREST doesn't say the modules are running in dual channel mode. So I think the info you found on the website gives the answer, but here are some explanation from Wikipedia to clarify the definitions:
*Dual-channel:*
"Dual-channel-enabled memory controllers utilize two 64-bit data channels, resulting in a total bandwidth of 128-bits, to move data from RAM to the CPU. In order to achieve this, two or more DDR/DDR2 SDRAM memory modules must be installed into matching banks, which are usually color coded on the motherboard. These separate channels allow each memory module access to the memory controller, increasing throughput bandwidth."
*DDR:*
"DDR SDRAM or double data rate synchronous dynamic random access memory is a class of memory integrated circuit used in computers. It achieves greater bandwidth than the preceding single data rate SDRAM by transferring data on the rising and falling edges of the clock signal (double pumped). Effectively, it doubles the transfer rate without increasing the frequency of the memory bus."
*DDR2:*
"Like DDR before it, DDR2 cells transfer data both on the rising and falling edge of the clock (a technique called "dual pumping"). The key difference between DDR and DDR2 is that in DDR2 the bus is clocked at twice the speed of the memory cells, so four words of data can be transferred per memory cell cycle. Thus, without speeding up the memory cells themselves, DDR2 can effectively operate at twice the bus speed of DDR."
*UMA (Unified Memory Architectrue):*
"In computer architecture, Shared Memory Architecture (SMA) refers to a design where the graphics chip does not have its own dedicated memory, and instead shares the main system RAM with the CPU and other components."

Memory upgradation problem in dv6226tx laptop

I have Pavilion dv6226tx notebook. Recently I upgraded my RAM to 4GB (2 x 2GB). When I goto BIOS it shows Installed Memory as 4096 MB. But under system properties in Windows it displays:
Installed Memory (RAM): 4GB (3GB usable)
I am using Windows 7 64-bit OS.
I know that 32 bit OS are incapable of handling RAM more than 3GB but why am I facing the problem in 64 bit OS, besides both windows and BIOS report amount of installed memory correctly as 4GB.
Is there any way that I may be able to utilise my full 4GB of RAM?

Hi:
For the storage controller driver, see if this works...
Download the drivers from this link below (second file listed -- 32 bit).
https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=2101&DwnldID=23060&keyword=Intel+Rap...
Extract (copy) the files onto a usb flash drive without any folders.
With the flash drive and W7 installation media plugged into the machine, boot from the W7 installation media.
After you select the install now option, select the Drive Options - Advanced menu, then select the Load Driver option.
You should now see the storage driver files listed.
If you check the box, it will only include the compatible driver.
Follow the prompts and hopefully, W7 will install.

Invalid Serial number and RAM memory upgrade problem

1. Please, I am trying to reinstall Snow Leopard, at the end is coming
"Invalid serial number entered Setup requires a valid serial number. The serial number has the format XSVR-106-x-xxx-xxx-xxx-xxx-xxx-xxx-x!
but my serial number is:
C07XXXXXXXXX!
What is wrong?
2. When I try to install 1 DDR Kingston 8GB PC3 10600 CL9 204-PIN SODIMM is coming a clicking sound, What is the problem?
Thanks.

All OS X Server 10.6 purchases include a product serial number key, and this serial number key is a required part of the OS X Server installation. This is a product activation key, and as shown in the display this key begins with XSVR-106 for OS X Server 10.6. This key was included with the paperwork from the original purchase on a couple of stickers on a card, if this system was acquired with OS X Server 10.6. If this OS X Server 10.6 media was acquired from elsewhere, then look for a sticker with the media and packaging. Otherwise, please contact the vendor and ask for the serial number for the media you've acquired. If you've purchased this Mac Mini with OS X Server 10.6 from Apple directly and no longer have the key, then you'll want to contact Apple Support for assistance.
As for your second (memory) question, presumably the memory is not compatible with your particular Mac Mini, or there's a problem with the memory itself. There are usually tech specs available listing the particular requirements for the memory for a particular Mac Mini system. If you purchased this memory from Kingston specifically for this particular system, contact the Kingston support folks and ask for assistance.
If you post the specific model of Mac Mini, somebody here can probably locate the memory requirements.

Macbook Pro (late 2008) memory upgrade problem

Hi,
I have an Macbook Pro (late 2008) 15'' 2.53GHz, 4GB DDR3, GeForce 9400m/9600M GT
4GB ram are by default. I tried to upgrade ram to 8GB, but my MBP doesn't recognize more than 4GB.
At Apple website I found information that maximum supported RAM memory is 4GB (which means that I cannot upgrade my MBP with 8GB of RAM), what isn't ok because it is a Pro machine. Are there some chipset drivers upgrade or BIOS firmware upgrade to let notebook to be able to has 8GB?

At Apple website I found information that maximum supported RAM memory is 4GB...
Yes, and that same information appeared in the specifications for your machine when you decided to buy it, and also in the owner's manual that came with it. So it's not a surprise — or at least it shouldn't be.
In spite of that information, and without support from Apple, you can put 6GB of RAM into it in the form of one 2GB and one 4GB module.

KM4M-L memory upgrade problem

Hello,
I've been running 2 x 256 MB DDR333 Crucial RAM sticks. However, I decided an upgrade to 2 x 1 GB is in order and bought 2 x 1 GB Kingmax DDR400 sticks.
Crucial sticks work fine in both memory banks. Kingmax memory works fine in right bank, however fails in left bank (BIOS won't POST, and no beeps at all). If I put Kingmax memory in both banks I get the same symptoms.
Please advise.
See signature for specifications.

If they do not take them back, experiment a bit more based on what previously was mentioned.
If you run CPU-Z and Everest Home, it should tell what timings the kingmax RAM is expecting at 333MHz DDR, then set it to that in BIOS.
Use one Crucial stick and in BIOS, manually set all relevant RAM timings and related. DDR@333MHz, Vdimm, example timings 3-3-3-7.
Then replace the Crucial stick with your kingmax. You might need a few tries, experiment with the timings while keeping the RAM voltage high.
When/If it posts, add then the other kingmax stick. Test for stability with e.g memtest86+. Can lower Vdimm again if that appears irrelevant.

Memory Upgrade Problem/Slot not Working

I have an HP Pavilion G7-1260us. The laptop came with 4 gigs of memory in one module in one slot. It is upgradeable to 8 gigs, 4 gigs in 2 slots. I purchased a 4 gig memory module, installed it and it didn't work. I figured the system wasn't reading this particular brand on memory so I took it back and got a different brand. The same thing happened. System didn't recognize the memory so I took out the installed memory, put the new one in and it worked. I took that out, put the installed memory in the other slot and it didn't work, so now, I'm fairly sure the slot isn't working. My question is this, if I purchase an 8 gig memory module and install it in the working slot, will that work and will the system show that I have 8 gigs? Or will this system only recognize 8 gigs if it's 2 4 gigs in each slot?
Thanks...
This question was solved.
View Solution.

   Hp Support Assistant should tell you what you have. Open up the HP Support Assistant and go to General Specifications, read down to slots. If it shows two slots then they are obviously functioning. If not, go to Device Manager to ensure that there is no conflict.
    It is also very-very of the utmost importance that the two memory cards are compatible with themselves and with your system's memory speed.. . . Which is? . . . .It is always best to have matching cards with sychronized speeds from a single vendor.
   As for: My question is this, if I purchase an 8 gig memory module and install it in the working slot, will that work and will the system show that I have 8 gigs? Or will this system only recognize 8 gigs if it's 2 4 gigs in each slot?
If your running Windows 7, Yes, your system will recognize and use the entire eight gigs.
If it were a rattler. . . .

Memory upgrade problem on Satellite L30-11D

Hi all
I am trying to update the memory from 512MB to 2GB.
I used Crucial's memory tester and ordered memory: 2X 1GB DDR2 667 CL5
I can use either chip in either memory slot but not both chips at the same time
I have updated the BIOS
Any ideas?
Cheers, rofleuk

Maybe you should use compatible DDR2 533 MHz modules. Compatible RAMs for this models are 1 GB with part number PA3411U-1M1G.

Memory upgrade problem on Satellite L300

My laptop is a Satellite L300 PSLB8A-047004. I purchased a kit of 2 x 2GB modules and inserted carefully following the instructions (they clicked into place). On restart the Power light was lit, the fan was on but no further activity, and the display remained black, no disk activity. Originally there was 1-off 1GB PC2-6400S module installed and Ive checked that the new ones are PC2-6400S. I took them out and put them back in but same result. When I put the original module back in it worked fine.
I then tried just one of the new modules in place of the original one but no luck so the original module is now back in and all seems OK.
Any suggestions please? If there was module damage from being handled then the original 1GB module should also be damaged as its the one thats been handled the most.
Kev.

This is typical behaviour by compatibility problems. Which modules you have, I mean who is manufacturer?
I recommend you to use high quality products from Kingston or Toshiba. For more info about compatible modules for your notebook visit http://www.kingston.com/worldwide/default.asp

Memory Upgrade for T61

Hi friends,
I have a T61 7663-xxx system, with 1 GB PC2-5300 667 MHz RAM. My Front Side Bus is 800 MHz ( I think so!), Everest software reports my memory controller is dual channel capable, and ~ 85% physical utilization of RAM. I have a nVidia Quadro NVS 140M 128 MB graphics card, but Everest reports 512 MB ?
I would like to upgrade my RAM, and buy some online.
a) Should I buy a similar 2 GB PC2-5300 RAM for my system for performance boost, running Windows XP 32 bit? If so, should I buy Lenovo RAM only, for maintaining my 3 year warranty intact?
Only ThinkPad and Lenovo memory will assume ThinkPad and Lenovo notebook systems limited warranty
b) What are the other best alternatives for good quality, reliable laptop memory, besides Lenovo?
c) Would it be better if I am able to buy RAM which can match my FSB? Will this have any performance benefit? Do these similar FSB speed RAM exist?
Kindly suggest top memory makers, if any.
I could not find any Lenovo 800 MHz memory from their website.
Kindly help me solve my memory upgrade problem.
I am a mechanical engineering student, hence I don't have any idea about FSB and the like, so I request the learned members to cast light on this area.
Info about reputed online sites in US, with fast delivery will be very much appreciated.
Thanks in advance.

Hmm. As far as I know, the internal graphics card can't be upgraded. There's some dock you can buy that lets you add a graphics card for use with an external monitor, but I don't know much about it. The cpu is more likely to be upgradeable, but don't attempt unless you know a decent amount about hardware servicing. Also, make sure the cpu will be supported by the motherboard! Best not to buy one with a clockspeed higher than what Lenovo sold (core 2 duo at 2.6 ghz).
Why do you want to upgrade so much? I run 2.1ghz with discrete graphics and 2gb ram under Vista, and it runs beautifully. If you have integrated graphics, then that might be a bit of a pain, but hey, you've got better battery life!
Anyway, I'd look more into de-cluttering your computer to speed stuff up. Remove anything you don't need, especially Lenovo tools that run in the background and you may not need. Turn off search indexing (slower searches, but faster overall performance). There are some nice guides online, if you google "vista tuneup."
Good luck! Enjoy your T61 as it is! It's a lovely laptop

Memory upgrade on iMac G3 700, help with system crashes

I tried to do a memory upgrade on my iMac, so I bought two kingston 256 MB PC133 modules, but none will work, the system starts, but hangs in about two minutes after loading the desktop. I went back to use the older memory module wich is an spectek, but I need the upgrade, any ideas?
Thanks!
FedericoMG.
Ps: Sorry about my english... I'm from Argentina... :-P

Hi Federicomg
The iMac 700 G3 should have been supplied with 1 stick of 256mb ram. However which is the correct type i am not sure as the Apple specifications for this model state PC100 whereas my iMac G3 700 graphite was supplied with 256 MB PC133-333 SDRAM
http://support.apple.com/specs/imac/iMacSummer2001.html
Apple profiler from my iMac this is the original supplied RAM from Apple:-
DIMM0/J13: Size: 256 MB
Type: SDRAM
Speed: PC133-333
1) I would re-instal the original ram and open system profiler to see what type the ram is.
2) Keeping the original stick in place add another stick of the new ram and look again in profiler to see if its recognised and again try the second stick to see if there's a problem with one of the sticks.
I am currently running my iMac with a small upgrade of RAM and the additional RAM is 128MB of PC100 and i have noticed the performance improvement since adding the PC100 so it's working and i have suffered no ill effects doing this..

MS-6195 memory upgrade

Hi,
My system is based on Ms-6195 K7 pro and Athlon 700 mhz. 192 Mb Ram (128Mb module + 64Mb module)
Problem:
when I try to upgrade memory with a sdram 256Mb PC100 module, the memory test can't finish and my system don't boot.
Please can you tell me how configure coreectly the BIOS or tell how to do.

MS-6195 memory upgrade.
I have also tried using new PC100 256Mb memory and am getting nowhere.
The ones that I have bought are single sided, [8 chips on only one side]
and do not work with my motherboard, however, if I put them into another,
older PC, it shows up as 128Mb.
So I assume that the DIMM is working OK, and that the 'old' PC has a memory size limitation??
I have tried the same things as wbs and Grommit and got the same results.
So I assume that the answer is in getting older DIMMs, double sided with 8 chips on either side.
Does this seem to be about right???

Memory upgrade fail - Kernel panic after put old memories back

I People, this is my first post here and unfortunately is to report a problem, not to help friends.
I did an memory upgrade last weekend. After this, he will not boot normally, only in safe mode.
I discovered that they sent me 1333Mhz memories, and my mac (mid 2009) supports only 1066Mhz.
I put the old memories again, however I believe that the system did not recognize.
As you can see below, the system recognizes two modules:
Memory Module: BANK 0/DIMM0, 4 GB, DDR3, 1067 MHz, 0x80CE, 0x4D34373142353237334448302D4348392020
Memory Module: BANK 1/DIMM0, 4 GB, DDR3, 1067 MHz, 0x80CE, 0x4D34373142353637334648302D4346382020
It is not true, I' using now 2 x 2GB, DDR3, 1067 Mhz (stock)
I tried to reinstall the system, but when I try, I got crash again.
how can I solve this issue?

Hi BGreg,
I already reset the PRAM as you said.
I've cleaned the memory modules as indicated by Linc above.
Today I formatted my harddrive to try a clean install, but system crashs after 5%, 10%.
There is something making me worried:
In one of my tries, I opened the system view to check my actual hardware configuration, and to my surprise, the system shows me 8GB installed. Cannot be. I have 2 x 2GB.
Where my system stores this information? There is a way to reset it? I tried last hour install the snow leopard, that cames with my mac, by DVD, but does not worked too.
Thank you all so far.
Giuliano

MS 7309 Memory Upgrade

I have a question regarding a memory upgrade for the MS 7309 (K9)motherboard; A60 BIOS, Upgraded to 800Mhz DDR2 memory from 5400, with WinXp OS. I am experiencing system stability problems with both 2 Gb sticks installed, the system is stable on one stick, total upgrade 4GB. There was initially only 2Gb, 5400 installed.
Should I overclock my system or update the BIOS? And if I need to overclock is there a process or utility to use to do this. The currently installed overclocking center utility does not work, is there an updated one?

To figure out what bios version you have, >>use the MSI HQ Forum USB flasher<<. After starting the MSI HQ Forum USB flasher it will automatically detect your board's current bios and save the details in a file on your desktop called MSIHQ_INFO.txt. There you can read up the exact bios version. You can quote this details here to make it easier for others to help you[/b]
