Mac Mini (mid 2010) horizontal screen flicker after new RAM installation

Hi, trying to help someone fix their mid 2010 mac mini here.
The model he bought came with 4GB of RAM; but he upgraded and put 8GB of RAM in. (the kingston variety KVR1066D3D4R7S/4GI 4GB DDR3-1066 I think)
Before the RAM there were no display problems, after installation small horizontal lines of flickering would appear around every minute or so. The screen is a Samsung 2333 Syncmaster connected via the mini display adaptor.
We've tried the display and adaptor in a Macbook Pro late 2008 and no problems so we think we've eliminated that variable. We've just gone through the screen calibration in Sys Prefs and we're still seeing if that's fixed it. We'll also try adjusting the refresh rate but we're doubtful.
Any ideas?

Apple support advised me to use RAM sold by Apple ($400 for 8GB).
I have 2x4GB hynix modules (by the way I had hynix stock modules in my mini) and if I mix 4GB(not Apple) and 1GB(Apple) it works just fine. It's obvious that 2 different modules won't work in dual channel BUT Xbench shows no difference in performance in any configuration. I tested different configurations: 2x4GB(not apple memory), 2x1GB(stock modules), 1Gb+4GB(stock and non stock) all of them show very similar performance +/- 3%.
This mean that mac mini doesn't use dual-channel memory mode (( There's also a chance that Xbench shows wrong results regarding RAM performance but to me, it seems very unlikely.

Express Server/RAM Installation

Hi All,
I have downloaded the oes6301nt from technet.oracle.com. I am trying to install express server on a NT 4.0 Workstation. The Oracle universal installer is not showing the Relational Access Manager product when you select Oracle Express Server 6.3 + Custom installation.
However it did install the relational access admin and RAA query statistics modules.
Any Suggestions?
thanx

Hi Ranjan and Dilys
Guess what? Even though earlier today, I put in a posting that I had no clue where exactly RAM is(see below) I just found out from where you can get RAM. This is so crazy. You need to install Oracle express client 6.3. When you are installing, you will see it will show you 4 options. The 3rd option is Express Administrator Install option. RAM, for some reason, is under that option. But now I am not sure if the express developer option and the administrator option will function smoothly if installed on the same machine/Oracle home. Since I just found this out and its Friday night, I wont know if the 2 will work from the same machine or not till Monday(ie. connecting to an Express Server on a different machine and Oracle DB on a 3 rd machine).
So good luck to the 2 of you and keep me posted how it goes.
Thanks
Das

DVD RAM installation

Hi everyone,
I have a BW G3 (listed below) running 10.2.x
I have a couple of questions: first of all, I just got a DVD RAM drive off a guy in town here for $5. I know the guy, so it's a good drive, he said it's in fine working condition. It's the Apple Model #LF-D111A
Anyway, I haven't attempted installing it yet - it's a simple IDE drive, but I have a couple of questions before I do.
First of all, he pulled this unit out of a G4, and it's listed as a G4 unit, but I read online that it can be installed in a BW G3 as long as you have the "decoder card" whatever that is! So first question: What is the decoder card? Do I have it? How do I get it? Is it worth it?
My second question is I plan to install OS Tiger on my system after I get the DVD RAM drive installed. Do you forsee any problems with this installation? Will I have to reinstall my program files?
Thanks so much!
Tim

The decoder module piggybacked to the B&W G3's OEM ATI Rage 128 graphics card. The earliest versions (1.x) of the Apple DVD Player program relied on hardware (MPEG-2) decoding, for viewing DVD movies. By the time that OS X shipped with newer Macs having faster CPUs, the Apple DVD Player program was able to use software decoding, not requiring the hardware decoder.

RAM installation question

Hi, I am upgrading a mid-2011 iMac from its original 4GB (2x2) of Ram to 16GB (4x4x4x4) of RAM.
--After i replaced the old 4GB with the new 16GB, I attempted to start the computer and was greeted with the dreaded Beeping that so many of written about.
-- However, when I replaced the old 4GB with 8GB (4x4) and used the SAME PORTS that the old RAM had previously occupied, everything worked fine.
--BUT, when messing around to try to understand the problem, I experienced the Dreaded Beeping with the 8 GB configuration as well.
--Also, when I tried to start the computer with new 8 GB RAM installed, but without the protective metal plate that covers the RAM ports, etc., the computer would not start at all.
Currently, the computer is running well on its new 8GB of RAM installed in the two ports previously occupied by the old RAM, with the outer plate re-attached.
So... the fact that my computer works with the new 8 GB of RAM, but has also not worked with the exact same 8 GB installed in the same ports leads me to hypothesize that possibly my problem is one of installation. This hypothesis is further supported by the fact that I had a small amount of resistance re-installing the metal plate that covers the RAM ports after I installed the 8GB, and I had even more resistance when I had the 16GB installed (It bulged).
I would like to install the remaining 2 sticks of RAM into the two remaining ports and have 16GB of RAM, which is the maximum suggested by apple.
Is is possible that I am just not pushing forcefully enough when I install the RAM?
Also, is it possible that the two ports that have been sitting unused need some sort of extra cleaning or lubrication?(i vacuumed out all visible fuzz, dust, etc.)?
I have watched a video on how to install the RAM, and am confident that I am doing so basically correctly. Any help would be much appreciated.

It's very unlikely that RAM from Crucial was bad when delivered. If, you purchased the correct RAM from Crucial, and you were careful and did not expose it to ESD when installing, and you fully inserted the RAM, then it should run great.
One easy way to determine if you have a bad stick at this point is to try two at a time in the slots that you know are working for you. If those two work then try the other two. If they work then all four sticks are fine. If not, then use the process of elimination to determine the bad one.
If they all work, then either you are not seating them fully in the remaining slots, or, one or more of the other slots have a physical problem. Try installing all of the RAM sticks again and then look at them all side by site. They should all look uniformly inserted at the same level. None should be bulging out on the ends or in the middle. They should all look like they are fully seated. In some cases it does take considerable force to fully seat a stick (the amount of force required is unfortunately relative and you will only be confident in the pressure that is required once you have done it on many machines). Just make sure to brace you hands so you are applying pressure straight into the slot with your thumbs.

Wallstreet and Tiger: no OS X 8GB "limit", issues if 512MB RAM installation

Since I felt that I could improve the performance of my [Wallstreet with Tiger|http://discussions.apple.com/thread.jspa?threadID=1390427&tstart=30], I decided to give a try to the break of the 8GB barrier as already reported in this forum so taking the occasion to substitute the 4200rpm 80GB disk with a 5400rpm one.
Again, acknowledgements to jpl, Tinkerman and others I do not recall for the helpful messages in the forum showing, if not else, that all this is possible. Unavoidable acknowledgements to the XPF developer too, of course.
I must admit that, while this time I was expecting a rapid installation after the method set out last time, actually I spent hours with any kind of issues of OS 9 either not installing or not booting even if from a disk cloned from the past working one. I was starting to think to some failed areas in the new disk but it appeared working in any other circumstance so eventually I realised that I was operating not only without the original CPU (Sonnet Crescendo 500MHz G4) but with 512MB of RAM and someone else already reported this as potential source of problems. Actually I realised it when, during one of the numerous serial attempts, the PowerBook remained with a black screen and suddenly produced the frightening "breaking glass sound", i.e. issues with the memory. Well, that was thrilling since I did not realise immediately what it was and I never heard it before...
So this time the method was the following:
- old disk removed from the Wallstreet and installed in a Firewire enclosure
- created three disk images on another recent PB G4 from the three partitions of the old disk (OS9, OS X, documents)
- new disk in FireWire enclosure, connected to the recent PB G4
- created two partitions in Utility Disk: 1GB HFS+, therestGB HFS+ Journaled
- installed new disk in Wallstreet
- reduced Wallstreet RAM to 256MB
- installed OS 9 from CD (and upgraded till 9.2.2) in the first 1GB partition together with XPF 4
- removed the disk and reinstalled in the FW enclosure
- cloned the old OS X disk image from the recent PB to the second big partition of the new disk
- reinstalled on the Wallstreet, started in OS 9, set XPF options as last time (Use Old NDRVs), boot in OS X
- copied all content of former third partition for documents in Documents
- restored the RAM to 512MB
Therefore the result is OS 9 in the first 1GB partition and OS X in the second 73GB and something partition. XPF mildly complained about the disk not having been formatted on OS 9 but setting OS 9 as helper was enough to satisfy it.
I am not 100% sure, say 95, but I have the feeling that, even after reducing the RAM to 256MB, the method to clone the old OS 9 partition to the new one did not work in the sense that the Wallstreet remained stuck at the question mark. Definitely it did not work with 512MB.
Summary (nothing new, just confirmations)
- OS X does not require to be installed in the first partition
- others (Tinkerman?) reported that this partition has to start in the first 8GB and not being included
- OS X partition can be more than 8GB
- watch out the RAM amount during installation (here it worked with 256MB but others reported 192 as maximum)
Hope this will help someone else.
Regards,
Giulio

Another installation procedure (still, similar to the previous one).
- reduce RAM to 256MB (some says 192 is better but now for me it was not feasible)
- with OS 9 CD: partition the disk,1GB/around 75GB, both HFS+ (there were few hiccups and I had to try more than once since the initialisation was failing and eventually I got a sort of ghost 5KB partition "for free")
- install OS 9 from CD to the 1GB partition
- update OS 9 to 9.2.2 through the installers
- mount disk in external enclosure connected to another system: initialise the around 75GB partition as HFS+ Journaled and cloned the old OS X partition to such partition (or install it for the ones that do not have such OS X partition ready)
- reinstall the disk into the Wallstreet and set up XPF (Use Old NDRVs); curious enough, here for the first time it said it could not boot from the second big OS X partition since it was "extending beyond the 8GB" or something similar still just choosing OS 9 as helper solved the issue
- restore the maximum RAM
- reboot in OS X
The OS 9 installation was done with the USB PCMCIA inserted and the USB mouse inserted in it. I do not know whether this was the solution (since also the previous time I selected all the USB additional extensions during OS 9 installation) but this time at the 9.1 update the mouse was recognised, not before, and it kept working since.
The Wallstreet just boots in OS X each and every time unless instructed to do differently through XPF.
The magnetic sensor issue still occasionally shows (apparently it needs "some time" or the Wallstreet just boots/wakes up nicely if just switched off or set to sleep). I will try to create some magnetic shield as already reported somewhere. Alternatively removing the two bays and waiting some five minutes or so does the trick.
What remains a bit unclear to me is the use of a magnet close to a hard disk, something I would consider the source of all evils if not properly done. I will study more, test and hopefully solve the issue.
Thanks,
Giulio

Another RAM installation goes unrecognized....

Have now made 3 attempts to install 2 new 1 GB sticks into Power Mac G5 Dual Core 2.0. There are two 1 GB sticks already in there that are working fine; these shipped with the computer. The new ones are said to be DDR2-533 PC2-4200 240 pin DIMM, unbuffered, non-ECC. They are made by Centon.
In Diagnostics, I read:
Power On Self-Test:*
*Last Run: 1/25/08 4:09 PM*
*Result: Failed*
*Failure type: Memory*
*Memory slots: DIMM2/J6900, DIMM3/J7000*
The memory slots read simply as empty in Memory.
Apple Hardware Test apparently was not supplied to me with my 10.4 disk set.
I just sent out a feeler to Centon to see about compatibility----their site has a 'memory matchmaker' click-through that suggests the ones I bought are correct for my computer....the packing slip that came with them suggests some potential differences or confusion....for example, the ones that shipped with the Mac are "2GB 533 DDR2 Non-ECC SDRAM", Centon packaging says nothing about the SDRAM part....additionally their packing slip says the sticks they sent are "267 Mhz" each although they are boxed and sold as 533 Mhz....
Anything I can do on my own to test or reinstall while I wait for a reply from them? anyone have experience, good or bad, with Centon products?
Thanks
EF

Hi
Apple Hardware Test apparently was not supplied to me with my 10.4 disk set.
The Apple Hardware Test is inside the same Tiger installation disc. You must restart your machine from the installation disc (pressing the C key) and you'll find it.
Ussually you must press hard the DIMMs to get them fine seated.
Besides that, you can try reset the NVRAM and PRAM:

System frequently crashing after RAM installation

Hi guys, this is probably a common question, but I searched these forums and haven't found exactly what I was looking for, sooo...
I have a Power Mac G4, Dual 1.25 GHz, Mirrored Drive Doors and had 768 MB RAM, and everything worked great. I just bought three 512 MB from Ramjet.com (2.5volt, 184pin, 256Mbit, 400Mhz, PC-3200 DDR400 High Performance SDRAM DIMM) and installed them, replacing the existing 256 MB card for the max of 2GB, which the system does recognize.
Unfortunately, now the computer keeps freezing up- playing World of Warcraft, downloading a video file from Safari, repairing disk permissions, etc... everything seems faster, but eventually it seems, after a while, crashes...
Is there an obvious step I'm missing that I can take before running Apple Hardware Test, like resetting something, or is that the next best step to take (or did i get the wrong RAM- I really hope not)?
Any suggestions would be greatly appreciated... thanks!
Colby

Hi
Many PC RAM suppliers do not have RAM that actually meets Apple's specs.
DDR PC2700 333MHz (Non ECC) 64x64 CL2.5 2.5v 184 Pin DIMM
is the correct spec for your Mac, even though 400MHz RAM may work, I would suggest buying the correct spec, esp. since your Mac clearly does not accept the RAM you have purchased.
DataMemorySystems has the correct spec512 MB cards for $45 a piece.

IBook G4 (mid 2005) RAM installation instructions

I'm looking for instructions on installing 1GB of RAM in my iBook. All the references to instructions are for 2004 models. Are the instructions the same for mine?

The directions are in the User's guide on Page 53. You can download the User's guide by clicking http://manuals.info.apple.com/enUS/iBook_G4_Mid_2005_UsersGuide.pdf

MacBook DIY RAM Installation = warranty violation?

Hope it's not too rude for me to ask this here since there's no MacBook forum yet...
Since it's apparently so easy to install RAM in the MacBook, I'm awfully tempted to order a pair of 1GB DIMMs in anticipation of a MacBook purchase in the next couple of days. Would I be voiding the warranty and/or my AppleCare agreement if I installed them myself, or would that be totally cool? TIA for your help...

There is a macbook forum now
http://discussions.apple.com/forum.jspa?forumID=1167
You would in no way viod your warranty if you instal RAM yourself. It is really the way to go as you can save several hundred dollars on the 2gb configuration.

Powerbook G4 RAM Installation

Hi Everyone!
Major Problem! I just got my 512 GB RAM card today and I installed it and my 15 inch titanium powerbook g4 seems to be acknowledging it... However, after 5 minutes of having my comptuer on, i'm asked to restart it. Why is it doing this to me and how can i make it stop? If anyone could help, I would love it. Thank you.

Return the RAM. It sounds faulty.

IS RAM installation the same for all new iMacs?

I want to remove the 4GB RAM from my 20" iMac (early 2008) and switch it for 2GB RAM from new 3.06 24" iMac. Is the technique the same for each computer?

Go to Crucial <http://www.crucial.com/store/listproductline.aspx?cat=ram&mfr=apple&submit=go> and find which Macs you have on their listings. That will tell you what RAM is in each.
If both are 800 MHz SDRAM, then they might be of similar configurations and could be swapped.

EMac RAM installation

We bought Leopard to install into our eMac G4. I was told that we needed at least 512 MB to run Leopard, so I bought 1 gig just to be sure I had enough. I opened the panel and there was no extra space to add memory. It's currently at 384MB, so would I be able to remove one of the existing memory sticks in order to add more memory? Would I lose all of the saved items that exist? What's my best move in this situation?

Hi Kiraly.
Your trouble free RAM doesn't surprise me as eMacs are quite robust. In my last post when I said installing 10.5 may be pushing the eMac a bit, I was speaking generally, not referring to RAM.
I have been aware of your upgrade to Leopard since you did it, and remember you reporting in the eMac forum that it travels along pretty well.

Additional Ram Installation?

I bought the MacPro with 2 GB installed on 4 512 sticks, one pair up on riser A, the second pair on riser B.
I installed 2 additional GB's, as one pair as follows:
Riser A/DIMM 1 512 MB
Riser A/DIMM 2 512 MB
Riser A/DIMM 3 512 MB
Riser A/DIMM 4 512 MB
Riser B/DIMM 1 1 GB
Riser B/DIMM 2 1 GB
So is this optimal, as the heat seems pretty high in A1 most of the time, ~70C?

I have the same RAM as you have. I know that Apple suggest filling A1, A2, then B1, B2 Then A3, A4... Exactly as you did.
There's a site that suggest otherwise:
http://peloche.smugmug.com/photos/91752872-O.jpg
So my config is 4B. You can try it. The riser A has a higher temperature so if you put the 2 X 1Gig in riser A, the the cooling is easier since there is only 2 chips, letting more air go thru.

Proper RAM installation/configuration

In the Apple manual they say to install RAM as follows:
1. Move the Apple module from the bottom card to the top (so that Apple RAM fills position 1&2)
2. Install the first additional pair on the bottom card to positions 1&2
3. Install the next pair on the bottom card in positions 3&4
However, an article at Bare Feats suggests a different approach:
"Though some of our configurations involved various size mixtures, we consulted with an engineer knowledgeable about the architecture of the "early 2008" Mac Pro. He suggested two things that may not show up in our benchmarking:
1. The pairs on the top riser (slots 1&2 or slots 3&4) should match the pairs in the bottom riser (slots 1&2 or slots 3&4) in terms of size if you want the maximum benefit to be gained by interleaving in real world applications.
2. The 2GB and 4GB FB-DIMMs are typically Dual-Rank (DR) while the 1GB FB-DIMMs tend to be Single-Rank. Ideally, you want all DR modules."
I decided to try the recommendation in #1, because I've been having the reboot from sleep issue and I hoped this might help. I have 4x2GB of TransIntl RAM. I installed the first pair in slots 1&2 on the top, the second pair in slots 1&2 on the bottom. Then I installed the Apple RAM in slots 3&4 on the top card.
http://www.barefeats.com/harper3.html
However, since I did that I'm now having systemwide problems: spinning beach balls, apps quitting unexpectedly, and other strange "nonspecific" issues. My system was running flawlessly prior to the RAM switch (other than the "reboot from sleep" issue, which many others have too).
Could the RAM configuration suggested by the engineer above be causing these problems?

PRAM resets from a Restart and not the same as from cold boot.
Personally, I would favor TechWorks memory. They should work together, but also give you something else to rule out Trans related issue.
One person bought Crucial 1GB x 2 and it would only work when they mixed the two:
Riser on top had Apple and Crucial in slots 1 and 2, same configuration on bottom Riser. Goes against conventional logic/wisdom, but DIMM slot 1 is like "master" and sets the timing for #2.
With new memory, testing with just the new RAM is one way to insure it works properly on its own, or with just 2 x 2GB and then with the other pair.
Leopard Cache Cleaner includes Memtest. Coctail is just running the same script to repair permissions as Disk Utility and I switched to LCC (and once in awhile used Onyx) but stopped using Cocktail, a few bugs at one time and stopped upgrading.
The reason for PRAM/NVRAM reset is to rebuild the Device Tree to insure it loads the correct information. On a restart, NVRAM is not rebuilt.
