Memory Question??? Where's Jocko?

I have a question on the memory frequencey showing in the bios of my motherboard it states that I have 200ddr is this correct? I have pc3500 mushkin 222. Is there a way to change this or is this just the way it shows?
amd 64 3400+
kt8 neo
34 gig wd 10000
radeon 9700 pro
2x512 mushkin 222 special
Thanks as always

Well, it's a limiter and it's not
It only allows you to set your memory at a certain speed WHEN not being OC'ed....
Let me explain:
At "FSB?" 200 and set to 400DDR you get 400DDR=200MHz
At "FSB?" 200 and set to 333DDR you get 333DDR=166MHz
BUT!!!!! Pay attention now!!!!
At "FSB?" 210 and set to 400DRR you get 420DDR=210MHz
At "FSB?" 210 and set to 333DDR you get 342DDR=177MHz (not sure if they are exact but should be close, just to get an idea)
The thing is, YOU DON'T HAVE A FSB!!!!!!
The thing they call "FSB?" in the BIOS is in fact only a reference clock, nothing more.
As the Memory controller is also running at CPU speed, the memory speed is a divider from the reference clock.
Another common mistake is that people think they have a north-bridge....well you have one, and it's located INSIDE the CPU...so if you change the reference clock you also change the NB (=memory controller) speed but the dividers/multipliers stay the same.
The only thing that doesn't change as far as I know is the Hyperthreading bus, that one is locked all the time, well at least it's here on my Opteron system, and should be the same on AMD64.

Memory question on Arch x86_64. 2x2048 MB = 3950 MB?

I have a naive memory question for some knowledgeable folks. My machine has 2x2 Gb sticks which should total to 4096. When I do a free -m under Arch, it's only showing 3950. Is the remaining 146 reserved or..?
$ free -m
total used free shared buffers cached
Mem: 3950 422 3528 0 28 157
-/+ buffers/cache: 236 3714
Swap: 2000 0 2000

Thats a really good question and the result you get is normal as far as I know.
Part of it (a small part I believe) is used by the kernel, the rest of it, and this is where things are not so clear, is reserved as an agp apperture.
As far as I could tell (I have stumbled uppon that too) the problem seems to be that some bioses don't setup everything as they should.
The thing is that some devices can only handle 32bit addresses so their address is somewhere until the 4GB mark, because the bios doesn't setup the memory remapping correctly (sometimes the user has no way set anything related to memory remapping, this seems to be the case with some desktop boards and most notebooks/laptops). This memory remapping "problem" was anticipated and there are ways to properly handle that.
For some reason unknown to me (and most people that have stumbled upon this) many bioses don't setup (or allow the setup) of proper remapping. To add to the problem the kernel seems to reserve 128MB of agp aperture by default even if you don't have an agp card, this reserved address space falls in the first 4GB of addressing space therefore stealing you some memory.
I have tried to regain those MB, I have tried to recompile the kernel with a different config and I've tried several kernel boot parameters and the only thing I could regain was 64MB if I recall correctly. I can't find now what I have added to regain those 64MB, I didn't keep that option in the kernel line, 64MB were not worth the possibility of having problems later on.
I know its a pain to have that voice in the back of your head telling you that there is some memory that is being wasted, specially if you have tried a 32bit kernel with support for 64GB of address space and got 4050 MB of usable memory, but just leave it as it is, it's not worth the time and the trouble.

I DO remember them but Apple chose to put them in Japanese and I can not change the language on Manage my Apple ID so I do not know if I made an error ,it threw me off , it was the wrong question Where did you fly to on your first Aiplane trip ? then I was unable to enter until 8 hours then called Apple Japan 4 times each time threy asked me would you like to speak with an English speaker,I said yes then they told me sorry today is Sunday no English speakers ,but they refused to speak Japanese, then I called 5th time and a kind guy could speak English we were on 1and 1/2 hours he got me to log in but the reset key chain could not be completed still pending.
He said do not mess with that ! then I got a text from somewhere to reset 4 pins suddenly it was very strange I said to him that I got this pin this morning but it said you can use maximum 3 hours it had a UK number and I told him I do not like this and will not enter the code he said do not do it if it is from the UK and then I said to him ok you did a lot to help but we can not go any further ! and we cut of I went back to my computer to re do the ID but I found everything a mess so I call and a stupid sounding Japanese women with a squeaky voice came on I was calm at first and they want your phone number your IMEI number your iPhone serial number date of birth Address email address it takes 10 munutes to check then they ask what are you caling about so I try to explain my keychain is broken or problems with language security questions and can not change my pasword because the security question have failed me so it is ONE BIG HEADACHE AND I START I GET STRESSED she says Do want an ENGLISH speaker ,I say yes ,that guy i talked to earlier but I never got his name and first time I ever talked to him but they said he is not here so I said ok and then she said today is sunday so call back in the morning ,I said ,well ok in Japanese but they make you feel stupid because they do not want to speak Jap@anese with none natives and they are to busy,And they feel that I should not bother them ,then I say that Apple Japan is trying to refuse Apple foreign customers and then she wants to hang up and ask me to visit the shop ,but they are the same I have a very bad time with Apple Japan since they do not discuss software problems or security with customer meaning if you have a problem they ask you to come on a time 20 minutes max so they do hardware test and say you phone is fine then I say no I can not reset my ID they say you must call call centre so I am going around in circles ,When I call English it is usually Australia so if my problem is in Japan surely if do not want me to talk to them in Japanese and they ask me to call Australia but every time my call charge is expensive after asking them is this free because I have Apple care they say yes but when the call goes to Australia 0120 277 535 it might change to paid call so I call then I have to ask is this charging they say we can not give you that information ! so what can I do I have have been at the computer and phone all day on my day off work and in tre week I am so busy and can not use my phone I can not work without it ,this new technology for you ,they can not cope with the fact that the customer have problems yet they do not want to deal with us because they can not solve it and so it shows them to be useless they like to walk around in their cool tee shirts and retro shop but when it comes to functionality we are unwelcome they got the money so do not return because apple is perfect that nothing should go wrong .
But it does somehow my English security answers do not work on a Japanese Question especialy if I did not choose that question I set up the multiple choice In English and wrote the answers in English or Roman and set them langauge preferences in English, do you really think you can correctly write english name or word in Japanese they write a police patrol car pato caa パトカア　they do not have r and l .So it is my choice to make my security easy for me and as difficult for others to hack.But they also have patororoo choo meaning ' now patrolling ' so why they have pato caa patrol car and patoro patrol and have thousands of Chinese words kanji they can find patrol.
I am getting off the topic but I am at a loss to fix this problem when they hold the keys and i have all the info to verify my ID.

Memory Question "4x1 Gig or 2x2 Gig?" what is faster?

Memory Question "*4x1 Gig or 2x2 Gig*?" what is faster?
I'm still don't know if witch to choose?
4 times 1 gigabyte Ram Memory is cheaper but if I choose for 2 times 2 GB Ram I can always beef it it later.
And is my memory faster if I'm using 4 slots with 1 gig over 2 slot with 2 gig?
I'm asking this question because I think using 4 times the memory bandwidth will be faster?

Hello Jan
Welcome to Apple Discussions
The iMac (Late 2009): Installing or replacing memory article and your User's Guide are pretty clear, they both say that +"You can use 2 GB or 4 GB RAM SO-DIMMs of 1066MHz DDR3 SDRAM in each slot."+ and not 1GB modules. > http://support.apple.com/kb/HT3918
To upgrade your ram you will want at least 2 more 2 or 4GB modules and add that to the current 2 x 2GB of ram. > http://eshop.macsales.com/shop/memory/iMac/DDR321.527

If you have a credit card on file on top of your gift card then it is asking you to confirm the security code for the card, which for a Visa or MasterCard is 3 digits located on the back, or AMEX has 4 digits on the front. This happens just to ensure that you are the account holder, and would happen from time to time whether it was a free or paid app, even if you have a credit through your gift card. This doesn't mean that your credit card will be charged.

Low memory question...urgent!

I'm having some problems with low memory. Earlier this evening, I tried to download an mp3 file which, it turned out, was too large to download. I noticed about an hour later that my memory had gone from just under 18KBs to just around 13KBs -- and now I'm getting the little hourglass icon a LOT. My BB is getting quite sluggish.
The file I tried to download, obviously, did not get downloaded. What's eaten up so much memory? Where did it go? How do I get it back? I tried pulling the battery -- twice.
Any suggestions? Thanks.

Quick question, where to put global variables

Very quick question:
where is the best place to put global variables,
(e.g. a flag that turns on debug mode)
if they are needed by the entire application?
I'm guessing they should be placed in their own class.
But should I make them public static final constants,
and just do Globals.MYCONSTANT
OR should i do "implements Globals" in all my other classes?
The first way seems simpler and more logical,
but in the examples for JSDT, they use the second technique.
Any thoughts?
thanks! =)

I would suggest either creating a properties file for your globals, or adding them to the system properties at startup. Placing items like debugging tags in your code means that you have to change the code, recompile, and rejar before your change is implemented. Using system properties means that you simply have to change your command-line options (i.e., from -Dmyapp.debug=true to -Dmyapp.debug=false).

After making a movie and wanting to burn a DVD, I go for iDVD in the 'DEEL' menu. Then I get the question ' where is iDVD? What is the problem?

After making a movie and wanting to burn a DVD, I go for iDVD in the 'DEEL' menu. After couple of seconds I get the question ' where is iDVD?
What is the problem? I cannot find iDVD in the programs map.

The current Apple thinking is that the entire world has access to fast broadband and wants to distribute home movies to friends and relatives via download (iCloud) rather than mailing them a DVD. The fact that nothing could be further from the truth has so far had no effect on this policy. If you scream and shout loudly enough down the phone Apple may send you a free copy of iDVD. That worked for some, but is now said to have been withdrawn by Apple. Also, you can complain bitterly here, perhaps suggesting that Apple could have provided a choice between using iCloud and burning DVDs:
http://www.apple.com/feedback/
Whilst Macs with a Superdrive continue to be able to burn video DVDs, the software for so doing, iDVD, is no longer included in the iLife bundle that comes with OS 10.7 Lion (which also omitted iWeb) or will come with OS 10.8 Mountain Lion. And it is no longer included in the iLife 11 from the online Apple Store: http://www.apple.com/ilife/. Your only solution is to look on Amazon or eBay and try to get an older version that includes iDVD.
However, the vastly more expensive FCPX can burn a DVD without iDVD or DVD Studio Pro involvement, but lack the themes etc of iDVD.

Newbie cluster question: where does the admin server live?

Hello, I'm looking at clustering for our application where I work, and so I'm reading through the cluster-related documentation for 11g. I have a sort of an architecture question: where should the admin server be started? Hypothetically speaking, if you have two nodes for your cluster, would the AdminServer run on a 3rd box which sort of stood in front of the two nodes?
Thanks much -

The ideal situation would be for your admin server to be separate from the machines hosting your managed server. This allows you to control access to the admin server, eliminate the performance impact if you have the admin + managed on the same host, and limits impact if youir #1 host fails, etc.
But companies may be unwilling to invest in a distinct (3rd) host just for the admin server, especially if you have multiple environments ( prod, testing, dev, etc. ).
So usually the admin winds up sharing the host with a managed server.

Memory Question for min 2011 iMac

I want to add more memory for my imac. I done the searches but I'm getting bits and pices of info so here are my questions ( I have 8gb of memory installed now. 2x4 gb)
1. how much can i put in the 16 apple says or 32 ive read? (or any inbetween)?
2. Apple sells the memory on their website ($200 is a lot for 8 gb) where can i find the same for less? ie. waht's the best memory for my imac out there?
3. It looks esy to install. Is it?
Thanks!

Your first line is just incorrect. It is what Apple TESTED the unit with when it was first in production.
Apple recommends only 8Gbs in both the late 2011 model MBPs and even on the Mid 2012 model MBPs when it can actually take 16GBs of RAM with No Problems. Other manufacturers do that also. I have a Dell E6420 that Dell and even Crucial state that it can only take 8GBs. I have 16GBs installed.
To order that 16GBs from Crucial I had to punch in my late 2011 MBP as the model. When I used the Dell E6420 it came up with 8GBs. The package I got from crucial stated Mac Memory. Works fine in my Dell as the Mac and Dell use the Same Intel Chipset.
It is up to the Intel Chipset as to how much memory can be installed. If the intel chipset supports 16GB you can use 16GBs. if it supports 32GBs you can install 32GBs
ComputerFixer wrote:
1) I would stick with the 16 apple says. While others may have gotten it to work on 32, there is a reason apple recommends 16.
2) Crucial and OWC are the best memory you can find. If you are looking for cheaper memory, PNY may work as well, but I would highly recommend using Crucial memory.
