Mac Pro :: RAM Works Better When Evenly Divided Between Ports
Dec 29, 2010
I've finally managed to decide (and scrape enough together) to purchase my macpro. I've decided on the base 2.8 which comes with 3 x 1gb ram sticks. I've decided to add two x 4gb sticks from Crucial with the 2 x 1 single sticks in the other ports giving me a total of a 10Gb machine. My only question is I've been told that machines run faster (or RAM works better) when it has evenly portioned between ports. i.e. the same amount in each RAM port.
So in my proposed setup I'd have an uneven portioning of RAM. So my question is: is the RAM even RAM port thing true? And if so would I notice the effect? 10GB should be fine for my needs but if there is an effect with uneven division of RAM would I be better going for 3 x 4GB sticks giving me12GB and simply leaving the 4th port vacant?
When I started up my iMac the USB ports stopped working. It didn't respond at all. The weird thing is that they work at the startup when you choose between Windows/Mac OS X when holding in ALT. They also work in Windows, but not in OS X. Does anyone know how to solve this problem?
I've got a Powerbook G4 that has a booting issue. I will hear the startup "dong" a whirl of the drive, then it doesn't go to the grey screen with the Apple. It just sits there with a black screen.If I wait a few hours and try it, sometimes it starts up fine, or sometimes it will sit on the grey screen with the Apple symbol and do nothing.If it does boot correctly, none of the USB ports work. Any ideas on if its worth trying to repair since its 2 and a half years old and I didn't get the Apple Extended Service plan?
My Mac screen is weird. Yesterday my Mac was making beeping nosies <--fixed. But today when I turn on my Mac the screen is divided by two... And it also has like weird lines all over the screen. I put in my pass word and the screen all of sudden just the screen is divided by two
During a botched Linux install. The partition was 64 GB, but now there are two, one is 45 GB and the other is about 20 GB. No earthly idea how I did that. How to restore them back to one single 64 GB partition, preferably without having to reformat and reinstall OS X.
I just installed a Seagate 500gb, 7200rpm hard drive in my 13" MBP that was updated to EFI Firmware Update 1.7. Clean install of OS X and iLife '09 & iWork '09 went fast. It's quite and fast compared to my old Samsung 500gb, 5400rpm hard drive. It was worth the $120 I spent on it!
Like two months ago, my MBP started to work really slow when not plugged to electricity, but as soon as I plug it in, my MBP works perfectly. I already sent it to apple for they to fix it, but they solved other issued except for that one. Please, any idea what could it be.
The Mac Pro only has 2 400 and 2 800 ports. and I was wondering if there was a way to get more, or split them. I have a lot of externals and an isight, etc. Or maybe a solution is daisy-chaining harddrives, does anyone know anything about this, or how to do it.. I'm afraid to experiment with my data.
Since apple is now in fashion to reduce the amount of ports in laptops, what do you think will happen to next MP model? Which ports do we loose and which will survive? Will there also be proprietary graphics cards with miniDP?
Is there any real use for Toslink port in consumer (prosumer) life? Or is it just for audio professionals? I can easily find Toslink cables for sale on web, but no attachments using such cables. So what is such connection for?
I bought a new micro SD card for my blackberry and I need to format it before it'll work. It came with a USB adapter but I have no idea how to access my USB ports. I've also heard that I can format it by putting it in the phone and accessing it as an external storage device, but I have no idea how to do that either.
I'm having a NAT issue while sharing my internet via ethernet to my xbox360. I've opened the required ports except for 88 in my router because it uses that for services (friggin belkin). I'm still getting a strict NAT on my xbox and I should have a Moderate NAT if I have every port but 88 open. I know that Tiger had a setting for port forwarding in system preferences, but for the life of me I cant find it in snow leopard. Does anyone know how I could forward the necessary ports?
I have the microsoft arc mouse and keyboard and each of them have seperate transrecievers. The macbook air only has two ports. If I bought a usb hub would this enable me to plug the transrecievers into the hub so I would have 1 usb port free? Im considering returning them and getting logtech's unifying transreciever, but they have no small keyboards that are compatible with it.
My usb ports in my c2d macbook don' t seem to be working. When I plug in my digital camera (sony) or itunes phone (motorola), nothing happens. I tried both of these devices on my 2 old powerbooks and they sync fine. Anyway I can check whether my macbook usb ports are functioning?
would it be possible to solder any wires to get power onto the USB ports on a G3 iMac? I have a blue 500Mhz model, if that would make any difference. the reason that I want to do this is because all of the iPods use USB now, and I would like to be able to charge mine while I am syncing it.
Hi, i have a 24" intel core 2 duo 2.4GHz imac aluminum 1 gb ram.
I first noticed this problem when i plugged in my ipod, it would not open itunes, appear in itunes, the desktop or finder. i managed to resolve this problem by reinstalling itunes and plugging in my ipod before i turned on the computer, but i can not change anything as it gets stuck while syncing with my ipod and says that my ipod is disconnected, i reconnect but the ipod not not appear on the screen.
All of a sudden a few days ago, I realized that my keyboard was not working. It was plugged into my 23" ACD. So I unplugged it and put it into my Mac Pro. It worked. So I decided that my ACD's USB ports were not working. A phone call to AppleCare and he told me to take the display for repair to the Apple Store. I just did that, and the USB's worked fine in the store. I take it home, still does not work. So I thought my USB ports on my Mac Pro must be bad. But everything else I plug into all three of the back ones works just fine; but my ACD does not. In the store, he used all of my own cables / power adapter. Why is my USB not working for my ACD but it is for everything else?
I just moved into a new apartment with my roommate and we got a new router - a Dlink DIR 615. For some reason, I can't seem to open the necessary ports for Transmission. I've been forwarding ports for Transmission forever now, and it always works. I've never done it, however, on a Dlink router - it's always been Linksys. Is there any difference between the two? Included is a screenshot of the settings. And to avoid all the obvious (I think) questions, I do have a static IP address, I have indeed set the right ports on both the settings and Transmission, and I have enabled everything (again, I think). I'm obviously missing something, but I have no idea what it is.
I occasionally have trouble charging my iPhone via my iMac USB ports. I plug in the iPhone, the screen indicators change to show that the phone is charging (green battery indicator and the lightning bolt symbol). However, when I come back to the phone several hours later, the charge indicator hasn't advanced any. For example, if the indicator showed half-full when I plugged it in, it remains half-full.
The iMac does go to sleep a few minutes after I leave it, but sleep has never precluded an iPhone battery charge on my MacBook, and most of the time it works on the iMac.
Is there anything, besides shutting down a computer, that causes a USB port to unpower while the iMac is sleeping? Does it matter whether I am logged in or simply at the login screen?
I recently went away for the weekend and when I came back my USB ports don't work. When I first start my 24" iMac the mouse lights up but then goes off later on when it's booting up. I really don't know what to do and i'm not even sure if I got any discs with my iMac as it had Leopard preloaded...
Sorry for the stupid question, but I looked and I couldn't find anything that explains it to me. I looked in the Network settings, and couldn't find it...
Basically, I am trying to troubleshoot a slow Transmission torrent download, and the one thing I can't do is 'check the ports' -- because I don't even know what that means.
I've got a first generation macbook (2006) and my HD crashed last night. Just wondering if this is a compatible replacement. I know it says pc/mac in the specs - but I'm not sure if there has been a change in the HD ports from first to second generation mackbooks.
i am looking for a specific Macbook pro verticale stand.The computer sits in it vertically, lengthways (sideways) and with the ports down that plug into the stand.There are ports on the back of the stand that you can use to plug the comp into an external monitor and usb and whatnot.I saw it on here a while ago but cannot remember where to find it
When I plug a wireless USB receiver for my wireless mouse into my USB drive that mouse will sometimes jump and not work but if i push up on the receiver it starts working perfectly, any ideas on what to do, the receiver is about the size of a thumb drive.
I brought my 3-year old ibook to the Mac store a few weeks ago because my USB ports stopped working. The kind genius behind the bar rebooted the ports during start up.
My ports stopped working again and wanted to try and reboot the ports. Can anyone tell me how to do that?
