I've bought new memory for my by my Mac Pro 2.8Mhz Quad Core mid 2010. It is 4x Kingston KTA-MP1066QR/8G memory. Installing went well, but it's clocked down to 800Mhz by the Mac. Why? And more important how can I fix it so I will have my 4x8GB @ 1066Mhz?
Info:
Mac Pro (Mid 2010), Mac OS X (10.6.8)
Can you mix old mac pro memory in the new mac pro?

As long as I stay in matched pairs, can I mix 600 and 800mhz RAM in my system?
View 1 Replies View RelatedI'm going to be purchasing my 1st Mac within a week or two and I have a question about Mac Pro FB-DIMM Memory placement -- seeing that the Mac Pro comes with 2GB Memory (2x1 GB Sticks) standard and I'm going to be adding an extra 8 GB (4x2GB Sticks) to the system (from OWC for an extra kick seeing that memory prices are very affordable for an extra 8GBs). Would the proper way to insert the 10 GBs of memory be that the each of the 1 GB sticks would go on each riser on Slots A1 and B1 (the first slots on the riser), with the other sets of FB-DIMMs being placed in pairs on each of the two risers? I read the Mac Pro RAM Info at [URL:...] but I just wanted to clarify if I got this correct.

and is there a defragmenter like on pc's..sorry for that devil word.
I have been viewing the forums for the past few months and have finally joined MacRumors as I have purchased an ibook G3 (first mac). I love it to death, it is so portable and even runs like a champ considering it is almost 4 years old. The ibook has a 800MHZ G3 processor along with maxed out ram at 640MB. Anyway I am planing on buying an TV before school starts up again and would like to encode my dvds to h.264. I was wondering if my computer can handle this task. BTW I would need to buy a dvd drive for my computer along with an external HDD. My other option is to buy a friends Powermac G4 with dual 1GHZ processors(he is selling it at $250) it already has a dvd drive and two 200GB HDD so that will save me ~ 150. As I am new to macs and would like to know if the Powermac will significantly make a difference in encoding times or should I just stick with my ibook and save the $100?
View 6 Replies View RelatedI've got a G4 iBook here that is really really slow. It's running Mac OS 10.3.9, has an 800Mhz G4 CPU, and 1.12GB of ram (Built in 128mb + 1GB upgrade).
Activity monitor shows over 800mb of ram free, and about 16000/0 page ins/outs.
The CPU is also about 80% idle.
Something is fishy. There is only 6GB of free hard drive space.. but I don't see how that could cause this nightmarishly slow performance. It takes 5 minutes to open a folder sometimes! Could it be bad ram? Malfunctioning hard drive? Does it sound like a hardware issue or software issue?
I also noticed that there were a few folders in the hard drive such as "Previous Systems" "Rescued files" and "Damaged files." I already trashed "Damaged files" because it was just a bunch of random crap that no one would need and it was taking up space.
Just wondering if anyone's tried to run Mac OSX 10.5 on their 800mhz G4 and how the performance is (good/bad)? Obviously the cutoff is 867mhz.
View 5 Replies View RelatedI've just installed Mac OS X Tiger on my iMac G4 17" i know Tiger is outdated, but it's faster than Leopard and Tiger still runs fine.now i tried to install Mac OS 9 too. For some performance reasons. But after the Welcome Screen, the Display turns black and i can't see nothing It's the original Mac OS 9 CD from the iMac G4. And it's the original rom, i never changed anything. Maybe Mac OS 9 doesn't have the right kext for the iMac?

I am working on a hardware hack with an iBook G4 800MHz where I can only power the iBook with the AC Adapter--NOT using the battery. When the compy is turned off and turned back on, I am getting this huge error message on the display that my time and date are wrong.
I gather there is no battery on the MB that sustains the internal clock--the compy uses the powerbook battery to keep the clock up to date?
Is there any way to set the system software to bypass or ignore the time and date? This computer is not connected to the internet, and time and date are irrelevant to my application.
Now, my poor little G4 was just standing there. After a lot of fumbling around, restores, it finally has regained life, running Tiger etc.
Now, I wanted to install Leopard, see for myself what I would prefer, and it would allow to tether wireless internet connection through my iPhone to the G4. But I need Leopard for that, Tiger is too old.
So, after Googling, I found out that if I put my Intel into Target Disk mode, I could use it as external DVD reader, seeing my G4's reader is dead as dead can be.
Further to one of my previous questions i have now managed to get hold of OSX tiger for my Imac G4 800mhz superdrive. However no matter what I try I cannot get this to install. If I go through custom instal it checks my disk and then comes up with a notice saying "mail cannot be intalled on this computer - intallation not possible" or something along these lines. I have also tried restarting while holding down the command button but the 10.4 disk does not appear. I have completely wiped my harddrive and reinstalled my original osx 10.3 and even taken out the airport card and additional ram memory card which i thought was causing the problem.
View 4 Replies View RelatedMy brother has a second gen, 800Mhz eMac (the one that could be overclocked to 1.33Ghz - the earlier PC133 ram model). Since about 1.5 mths ago, when he powers it on, sometimes it will not power on, and other times it will give three beeps (diagnostic pages say bad RAM) and a flashing power/sleep light in unison with the beeps. Did this vintage suffer bad caps? I recall that it was only the 1.25Ghz model that had bad caps, but I could be wrong.

View 5 Replies View RelatedDoes anyone know how the ATI Radeon HD 2400 XT with 128MB compares on performance to the shared 256MB in new Minis? Also, in iMacs with an 800mhz system bus that have 667mhz ram preinstalled, will they take (and run at full capacity) 800mhz ram?
View 1 Replies View RelatedI know that's below the required speed but there's Leopard Assist. As can be seen on that page, it says "Uncertain" ONLY for my iMac.
Has anyone done it with this iMac? Does anyone know? I'm running Panther now and, these days, that's no place to be. I want to get Leopard on my Mac before I have to <shudder> switch back!
And my second question is, where can I buy Leopard cheaply? It costs about £100-200 on eBay for something that I will need once.

I have a iMac DV G3/500 (Special Edition) from summer 2000. Anyway, I am using Mac OS 10.2.8. Recently, my start up disk's memory has gone done from 1.2 GB available free space to 668MB (currently). I haven't saved anything on this disk so I can not understand why this memory has dissappeared. I have also had icons on the start up menu disappear. Could someone please tell me how I can restore the missing memory?
I have a Black MacBook (Early 2008). I think that I still have the factory standard RAM sticks (I bought the Mac used from a friend). I noticed today that I am running on only one gig of RAM even though I have two gigs of memory.

View 8 Replies View RelatedI just bought a early 2009 MAC Pro and it came with 3GB of RAM, I ordered 3 2GB sticks of memory to replace the 3 1GB sticks that I had in there from Kingston. I turned off the unit, I popped the little levers and pulled the memory out of slot 1, 2, 3 and then replaced the memory with the new Kingston in slot 1, 2, 3
One of the sticks in is not working at all and I get the RED LED light no matter what slot I move that chip to. So I am running on 2 of the new Kingston memory chips.
Can I mix the memory and add the 1GB into slot 3 and 4 with slot 1 and 2 full of 2GB chips?
Also how to I run the memory utility again? I went to /system/Library/CoreServices/ and then I see the program Memory Slot Utility.app
How do I run this? I'm used to no spaces and I type ./then program name
I've just updated the os to 10.6.2 and my 16gb mac pro 1,1 only shows 8gb in the system profiler. The memory tab shows they're all working correctly but size says "2gb" where should be "4gb".

Why does OS-X do that?!
Also, if I have 1 gig of memory left (out of 180 or so) why does it disappear to 0 if I open photoshop? I'm used to a PC running virtual memory and CPU but why does the Mac actually take away my available memory?I'm at my wits end here, it's been driving me up the wall for weeks!
Im trying to figure out how much memory to order for my mac pro which will be ordered soon. I know the more the better but there must come to a point where it makes little difference?
My primary uses are lightroom, photoshop (amateur/prosumer level) as well as running windows XP and possibly 7 inside Fusion.
Would 8gb be enough or would 12 make a substantial difference ?
Is there a big real world difference between running in dual or triple channel?
