Mem Error- added 512 Ram to (k7t266 pro-2

When I joyously added 512 more ram (already had 512) to my MB I a blue screen Mem error.
I checked the Knowledge base and did what it said. didn't say much either.
[email protected]
Someone help me!

Which os? Win98 doesn't support more than 512MB.
Tested your ram with Memtest86?
Increased the ddram voltage? This was very helpfull for the combination K7T266Pro2 and huge ram in the past.

Adding more RAM to Macbook Pro mid-2012

Hi!
I have a question about adding more RAM to my mid-2012 MacBook Pro (without Retina). I've been doing some video editing with Final Cut, and I'm using quite many apps on the daily basis. I have the standard configuration with 4GB of RAM (2x 2GB) but I guess I should upgrade it, shouldn't I?
I had that idea in mind: buying extra 8GB RAM instead of one 2GB, so I'll end up with 10GB of RAM. If it won't be enough and I'll have some extra money, I will add another 8GB instead of 2GB, so I'll have 16GB.
First question - is it worth it?
Second question - can I add any RAMs supported by Macs? For example I'll leave one 2GB that I have already, and add 8GB made by, let's say, Kingston (I guess they are supported and they have good price in my country). Will this work fine? Does it make sense?

Jerroslaw,
since you’re running Mavericks, open up Activity Monitor while you’ve got your usual selection of apps running, select its Memory tab, and look at the Swap Used setting in the lower left. If it’s displaying “0 bytes” as the amount of swap used, then extra RAM won’t make a difference. Otherwise, to answer your first question, whether it’s worth it or not depends upon how frustrated you are running your usual selection of apps with 4 GB of RAM. It might be that the cost of replacement RAM modules outweighs your level of frustration — only you can make that determination of worth. I would recommend that if you do choose to purchase replacement RAM, that you get a pair of matching modules — either 2 × 4 GB = 8 GB, or 2 × 8 GB = 16 GB, to replace the pair that is currently installed.
For your second question, you don’t have to use Apple-brand RAM, but you do have to use RAM with the same characteristics as your factory-installed RAM uses. Any worthwhile purveyor of RAM for Macs will let you easily locate modules that are compatible with your Mid 2012 MacBook Pro.

Adding mismatched RAM on MacBook Pro ?

Hi,
I have a 2.0 Ghz MacBook Pro with the 512 MB Stock RAM that it came with.
I would like to add 1 Gig of Mac Compatible Corsair or other branded RAM.
Do I have to install matched RAM in this computer ?
Does it matter if the RAM I buy matches the brand of RAM already installed or if it is the same amount ? I am honestly really confused about this.
Ram prices are really low in Canada right now so I want to take advantage of this but at the same time, want to make sure that the $84.00 CDN that I am planning to spend on this extra 1 Gig will make a siginficant or at least noticable difference in my MBP performance.
Thank you for any recommendations or suggestions you may have.
Kallum

KMoorehouse,
First, I'll tell you that all of the Macbook Pros use the same memory: 667MHz DDR2 SODIMMs. And, had I not noticed that you are in Canada, I would have recommended RAM from the same place tat the other poster did. In fact, I will provide two links:
For a 1 GB module
For a 2 GB "kit" (2 X 1 GB)
I purchase all of my RAM from this company, and I have been doing so for several years. I have never had a RAM-related problem, and they provide very good service.
I realize that there may be difficulties for you, being in Canada, and I do not know what those difficulties might be. If you can order from them with no problems, it might be worth it. Give them a call to find out what the ramifications would be ordering from Canada.
Going to 1.5 GBs will provide a world of difference for your MBP, if that is all you can afford. 512 MBs is simply not enough even for just OS X; add an application or two to the mix, and your MBP's performance will be really poor. Even going to 1 GB by adding a second 512 MB DIMM would provide significant benefits, and it would additionally enable Dual-Channel mode. I think that the additional benefit of having 1.5 GBs will be greater, however.

Adding more RAM to MacBook Pro Help!

Dear Apple Support Community,
Ok so first of all don't tell me to go search for older discussions >:(
Here are my system specs:
MacBook Pro 15", Mid 2010
Processor - 2.66 GHz Intel Core i7
Memory    - 4GB 1067 MHz DDR3
Graphics   - NVIDIA GeForce GT 330M 512 MB
Software   - OS X 10.8.5 Mountain Lion
I was going to buy some extra RAM and boost up my computer to about 16 GB total because my computer is running a bit sluggish lately when I'm running several apps at once (such as pages, keynote, chrome, steam, itunes...) but now that I've seen a few videos online and some reviews on amazon, I'm not completely sure which RAM is the one that will not screw up my computer. I saw a video on 'UnboxTherapy's Channel' where he said something about the timing of the RAM which is in the format like 9-9-9-24 or something, as well as some review saying something about the computer not working at all thanks to the RAM because the computers didn't match..
Please help me find a 16GB RAM that will work on my computer (please try and keep the websites amazon if possible, I live in japan :/)
and please explain to me what the RAM timings mean and how to figure out my timing...
Thank you for reading

Hi leroy,
Thanks for the quick reply!
I checked the Crucial site, and apparently my Macbook Pro can only upgrade until 8GB...
Is there any way to upgrade to 16GB without any trouble?
Also, if I upgrade to 8GB, will I see any difference? Some users say that you won't see much change between 4GB and 8GB of RAM... Is this true?
Thanks!

Adding new RAM to Mac Pro

I just got my new Mac Pro. It comes with (2) 1G sticks of DDR2 RAM. I bought (4) 2G sticks of DDR2 RAM from OWC to put in it. Can I just add my 2G sticks and keep the 1G sticks in, or do they all have to be the same size?
I spoke with 2 different Apple reps on the phone today, and they gave me 2 different answers. One said no - they all have to be the same size. The other said I could use different sizes, but they just have to be paired.
Anyone know what the right answer is?

Hi
my Mac Pro configuration in the system profiler only shows 512MB cards in Raiser B DIMM1 and DIMM2, allthough I have added new 2G cards into Raiser A DIMM3 and DIMM4.
The Raiser A DIMM1 and DIMM2 slots are occupied by 512MB cards as well, but these are also not visible in the Memory Slot summary.
Question: It seems I have 6GB memory, but only 1 MB visible in the Memory Slot summary. Is this possible and how can I activate the whole memory?

Adding 16GB Ram to Macbook Pro

I purchased a Macbook Pro and would like to add ram memory. I have recently read that the MacBook Pro 15-inch 2.5GHz quad-core Intel Core i7 is capable of having 16GB of ram added: CNET http://reviews.cnet.com/8301-13727_7-20125391-263/add-16gb-ram-to-your-macbook-p ro/?tag=mncol;1n
Has anyone done this and what is Apples support policy?

Maximum Memory
16 GB (Actual) 8 GB (Apple)
Memory Slots
2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
Many have done it. It is a permitted user upgrade. It does not void the warranty, although if you damage the computer in the process of installing the RAM that damage will not be covered under the warranty.

Adding more RAM to my Pro Mac - config?

Hello folks,
I'm considering buying from OWC (one-third the cost of buying from Apple) - 8GB (2GBx4) PC5300 DDR2 ECC 667MHz 240 Pin FB-DIMMs.
Specifically:
8.0GB OWC Matched Set (2GB x 4) PC5300 DDR2 ECC 667MHz 240 Pin FB-DIMM Modules for all Mac Pro Quad Core and 8 Core systems.
OWC claims these chip sets are Apple qualified memory and they offer their "LifeTime Advance Replacement Warranty" with them. The cooling fins appear identical to the Apple RAM I have already in my Pro Mac.
My config is as follows:
A1 1gb
A2 1gb
A3 >>> proposed 2gb
A4 >>> proposed 2gb
B1 1gb
B2 1gb
B3 empty
B4 empty
Would the above configuration be the correct way to install this new RAM?
Thanks,
mp

Hello Hatter,
I've been so busy on this thing... Update for ya;
OWC RAM arrived the other day; I've had it installed for 2 days now. I did remove my existing (4) 1GB DIMMs before installing the new (4) 2GB DIMMs. Also, I installed smcFanControl.
I've not yet re-installed my original (4) 1GB DIMMs; I think I'll add reinsert them tomorrow...
I ran a TechToolPro test on the 8GB of new DIMMs a few times, and so far everything is perfect. I haven't done any "heavy" dual-core lifting yet. Maybe tomorrow I'll play around in Photoshop and kick the crap outta my new DIMMs.
On the smcFan speeds: Out of the box, the fan speeds are all set at 500rpm. I kicked them all up to 1150rpm - and the temp. dropped from 40°C to 35°C in about 3 minutes. Literally, my MacPro is a cool machine. It's quiet too, I can't hear the fans that much, just an occasional sound - not of rushing wind but the motor - a VERY SLIGHT, SUBTLE harmonic vibration (that description doesn't do its gentle hum justice...) It sounds a little like an old fish tank water pump - very very subtle vibration-like periodical rattle. I'm guessing its a fan's blades slightly out of balance??
Yes, I dusted the heck out of the entire Mac Pro before doing any work on it - so the rattle (again, not a terribly noticeable noice at all) isn't dust. Bearings perhaps?? Anyway -
Question: What are you referring to as the "base" fan? I see four:
1. the CPU Fan
2. PCIe/HDD
3. Rear Fan
4. Power SUpply
Is there a vast difference if - say - the front fans are slower than the rear fans? That is a condition that would ostensibly create negative pressure within the box - and THAT (deductively) would improve airflow, wouldn't it?
Speaking of airflow, I noticed that OWC's DIMMs have not four but about 7-8 fins on each side of the chip sets. I would deduce that more fins equates to greater heat dissipation... But these fins are closer together - which could reduce the air flow between fins. Such dilemmas... :-/ Anyone out there care to comment on more fins meaning more cooling?
Lastly, can the temp. range be too low? Is a temp. range below 40°C a bad thing?
Thanks hatter (and everyone else!),
Cheers,
mp
oh - the other non-RAM issue - it was 10 bad blocks on a 500GB disc. I had a means to back-up the VM guts - and that was enough of a back-up to proceed with a wipe-reload scenario!

Re: Adding more RAM to Macbook Pro mid-2012

Hi,
I am in the same situation as Jerroslaw, but in my case my "swap" says "0 bytes". what would be the best idea to increase my RAM?
sorry for my lack of knowledge in this area..

Ah! You're running CAD software! Yes, you could surely benefit with a RAM upgrade. To me, 8GB of RAM is the 'sweet spot' for RAM on any Mac - you can upgrade the RAM to either 8GB or 16GB (the maximum).
Around here we tend to recommend Crucial and OWC RAM - it simply works with no problems with MacBook Pros where cheaper, 'value' RAM has trouble more likely than not. Visit the Crucial website and click on the System Scanner tab and download the small app. Unzip and run it and you'll be taken to the Crucial site with the exact upgrade options for your particular model. The exact specification for your machine are 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMMs. You can also check OWC - I just prefer Crucial because it's usually less expensive than OWC and it's what I run in my machine.
Visit both sites and check out their offerings...

Adding more RAM to Macbook Pro

I'm currently using a MacBook Pro 13" Mid 2012 model.
At the moment, it has 4GB of RAM and I would like to upgrade it to 8GB of RAM. I will soon purchase DDR3 8GB of RAM and install it myself, however I have a little query, will 8GB of RAM drain my MacBook Pro battery life quicker? I wanted to have a stronger and faster computer.
Thanks for your support,
IxE TeMpTeD

Welcome to the Apple Support Communities
A faster computer consumes more energy than a slower computer. The battery life will be similar or the same when you install more memory, but of course, it will be less when you open more apps than the ones you had opened with 4 GB of memory, because 8 GB of memory allows you to open more heavy apps at the same time, consuming energy

WOW!!!! Added 1GB ram to Macbook Pro C2D - Now Aperture Flies!!!!!

I now have 2GB or ram in my 2.16Ghz C2D - - Aperture is a lot faster - it's actually a night and day difference on my setup!!! Yay for dual-channel!!!

I wouldn't even consider a laptop. I upgraded from an iMac 17 to a 24 over three years ago and now it seems small c/w the 27.
I use my old 17 when I go on the road as it goes into a padded bag along with the keyboard and mouse and only takes minutes to set up.
You'll get far more bang for your buck with a desktop and it will last you a lot longer. MacBooks are famous for hard drive failure and I wouldn't bother with one until they are fitted with flash drives as standard.
Me, I'm waiting for a 17 inch Airbook to appear.

Adding more than 2Gb RAM to MacBook Pro

Do you guys know of any way to put more than 2Gb RAM in an Intel 17" MacBook Pro?
Model Name: MacBook Pro 17"
Model Identifier: MacBookPro1,2
Processor Name: Intel Core Duo
Processor Speed: 2.16 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache (per processor): 2 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: MBP12.0061.B03
SMC Version: 1.5f10
I bought this when the 17" models first came out, and have been disappointed in it ever since (I broke my rule of NOT buying the first generation of something). As time has passed, the main problem is the 2Gb limit for RAM. That's NOWHERE near enough, and shame on Apple for that limitation. If there were some way, even a non-standard way, of adding more RAM, I could get reasonable performance from this computer. As it is, this has been a wasted $3600 investment. whew!
Any help or ideas would be appreciated. Thanks! Feel free to email bruce at dbsdesigngroup.com

That's possible...actually likely. I'd love for that to be the case because I could fix it. ::Grin:: It's been this way since I first got it. When it arrived with just 1 Gb RAM, it was virtually unusable. I have a few apps as startup items, but they're just Firefox, Entourage, iNotepad, Linotype Font Explorer (with very few fonts activated), and Stickies. That shouldn't affect things much.
My needs are to use Photoshop, Illustrator and GoLive at the same time, with MSWord, Firefox and Entourage open as well. After the first bit of usage, I end up with 4-6 pageouts and a VERY slow computer. While it's doing the pageouts (which take quite a while), or switching between apps, it's very slow. And it's also extremly slow when Spotlight is indexing, so I disabled that.
I'm just not sure what it might be...nothing in Activity Monitor seems like it would be a culprit. Even in Safe Mode the problem is very evident.
I'll keep exploring and hopefully find something that will make this machine more viable for my use. I really appreciate the input greatly.

[VIA] K7T266 PRO- RU motherboard: Windows XP on a RAID ARRAY (fasttrak100 LITE)

Hi All!
I have a
MSI K7T266 PRO- RU motherboard, BIOS is the latest, official from MSI website,
Problem short description: Windows XP (sp1 or sp2 english, I tried both)
will not install when I set 2 x 40 Gig = ~80 Gig Stripe Array.
detailed description:
motherboard K7T266 PRO- RU BIOS 1.9 AMI BIOS.
AMD ATHLON XP 1700 + "Palomino" microprocessor, at default speeds.
one piece of 512 PC 3200 RAM, can tell details later.
Power supply: 400 W CODEGEN model : 300X.
HDD-s : one IBM deskstar, fully functional, and a SEAGATE barracuda. seagate SEATOOLS, IBM DFT 32 no errors both.
I set in the FASTTRAK 100 LITE "PDC20276R" (written on the chip) bios a STRIPE array. Powerquest drive magic , or the Windows XP CD handles it fine , as a 80 gig disk.
I downloaded ALL available versions of the FASTTAK 100 LITE driver from the MSI website.
(only tried: MSI driver FASTTRAK 100 lite, the only available driver on the MSI website, and various drivers from www.promise.com) ( http://www.promise.com/support/download/download2_eng.asp?productId=15&category=driver&os=0&go=GO ) (but I guess they WONT support my raid controller on the motherboard)
Windows XP CD , booting, Press F6 for additional RAID /SCSI drivers, I put in the floppy, choose WinXP fasttrak lite driver, windows continues, even formatting the 80 GIG disk, copy files- access the FASTTRAK.SYS driver, EITHER it says: no fixed disk present, press F3 to exit windows setup, or windows setup continues, copies files, reboots, and then STOP ERROR
http://www.martin555.dyndns.org/stop.jpg
please, help me with the following:
how to install XP on a raid array.
is it worth, will it be little bit faster disk load times etc?
is it secure if I trust the HDD-s?
any clue, how to overclock the AMD 1700+ athlon XP palomino to its maximum, but still stability?
AND : I read a lot about some MOD-ded BIOS called " KUNIBERT" , which makes the LITE raid to a FULL RAID and some other extras? where to get it and what to do?
email me if you can martin5 "at" freemail.hu
THANKS !

pardon me, dump? my english is not very perfect.. you mean to trow away, replace to something better, more stable power supply, more powerful?
you must see... first I would like to resolve the "installing XP on a raid array" problem,( how is it possible, is it worth, will it speed up hard disk access and load times... etc... ) and after that maybe I will OC the machine...
it is now , with a 8 cm ventillator and a large aluminium cooler 39 Celsius IDLE and goes to 45 Celsius during EVEREST benchmarking test. (temperatures on 1700+ default setting and OC-'d to 1900+. just experiencing with it. ) (I saw the toms hardware guide movie , smoking processors..)
cheers, Marton.

K7T266 Pro w/ Athlon XP 2000+

Specs:
K7T266 Pro
AMD Athlon XP 2000+
512 MB DDR (2100)
80GB + 40GB (IDE)
GeForce 4 MX440
At first i used a Duron 1200 and run fine, but not fast enough. I bought myself an Athlon XP 2000+ that came from an other fine running machine. I've updated my bios so it would support that processor. I've installed the 2000+. I set my fsb to 133. The motheboard boots. While WinXP starts i get an Bluescreen, not a defined error, just an 'error' (micersooooft...). Even when i try to install WinXP, i get errors (bluescreens) When i manually set the fsb to 133 and my multiplyer to 12.5 (to get the 1667 for 2000+) the motherboard doesn't even boot.
this is a generated html page of my system.
http://users.skynet.be/fa006592/index.html
Plz suggestions ? i just want the 1667 run like it should be.

Too much APIC, but many suggests this idea:
"Although I'm not entirely clear on the a c o m p l e t e l y fresh installation of Windows XP is required (with APIC mode disabled)."
Here is something to read, if you like. http://www.hardwareanalysis.com/content/topic/13533/
But again, I want to know more about the error message.
Are your temps high?
This is an idea of a BSOD for APIC:

Having trouble installing Radeon 7500 into K7T266 Pro

I am having all sorts of problems switching from my nVidia TNT 2 (MaxiGamer Cougar) video card to my new Radeon 7500. I am running an AMD Athlon 1400 with 512 MB DDR RAM.
I have the K7T266 Pro (MS-6380) chipset.
Can anyone think of what I am missing here. I think I have all the updates AGP drivers I need but I am not sure. I get lock ups prior to windows starting everytime. Even in safe mode.
Grrrr.

I ended having to format my c drive. Windows began doing some really funny things and then never started again with old or new video cards. I have re-installed windows but now sometimes my monitor stays blank when I start the computer. It is supposed to wake itself up but when it does, it has no picture. To solve this I shut down and flick the switch on the back and discharge everything. It then works again for another few times. Do you think this may be a problem with my power supply? I have an Enermax 350W. I bought it when I built the computer and figured it would have plenty of juice.
Thanks for you help

2. after the above problem, i proceeded to attemp to install win xp again. i wasnt succesful because i always get a message saying cannot copy whatever.dll file all the time. so the installation wont continue.
i hope u can all help me. i feel that the win xp cd might be busted, but then again i am also concerned about problem #1 above. i feel that if i can install windows again i will have the same "spontanous restart" incident that first started and caused (i think) probelm #2
pls help.
thanks
Anton ;(

Hi!
Really, I don't think this could be a hardware problem since WinXp takes more than few minutes to install, and you did it, then you installed drivers and SP1. Why did you format HD in the other PC ? I would try a new install, taking out all not necesary stuff, leaving only CPU, memory and video card and formatting again the HD. for a clean install; then go adding the other hardware one by one, installing it's drivers and rebooting each time. Finally before connecting to internet enable Firewall to prevent Blaster Worm ( Don't know if still is going around ). One thing: Be sure HD is well connected and configured: Master if is a slave conected to same wire..etc.- If again you get an error, I would look for a faulty HD. 8)
