My MacPro 1,1 takes 667 MHz DDR2 FB-DIMM memory module. I'm confused by the F designation (PC2-5300F) What's the F for? Will these work for me?

Well, Philip, I'll provide my opinion. I suspect that the "F" refers to "Fully Buffered". As to whether they would work for your MacPro 1.1, I don't know. I would recommend contacting someone at an Apple Store or obtaining the specs for your motherboard within the MacPro. Check the existing memory within the MacPro and determine whether it is fully buffered. You can't mix fully buffered and non-buffered memory together, based on my research and experience.

The F at the end of the code (PC2-5300F) means that it is "fully buffered" which means that it has a different pin and slot shape. This will not fit in a system that does not take FB DIMMs, so for your standard home system, this will not work (just as standard RAM will not fit in a system that uses FB RAM).

FB means "Fully Buffered"............. this type of RAM is more commonly used for server systems, not PCs............... as for your specs, it does not seem that this will work for your MacPro

The F stands for "Fully Buffered", which does appear to be indicated for your MacPro.

I think it mean full buffered. You will have to check the MacPro spec to see what kind of memory it support. I used this for Windows server Dell Poweredge 1900.

I'm pretty sure the Mac uses a different type of memory. I think I saw one that was for Macs when I was doing my search. I would go on the Crucial.com website and see what they recommend to make sure.

See Mfgr website at http://www.crucial.com/store/listmodule/DDR2/list.html. That should tell you everything about it.

Basically out of the box..this notebook has Slot 'ChannelA-DIMM0' has 4096 MBSlot 'ChannelA-DIMM1' is EmptySlot 'ChannelB-DIMM0' has 4096 MB (serial number xxxx2019)Slot 'ChannelB-DIMM1' is EmptySo with two empty slots my initial thought is yeah if you matched up the same memory sticks...there are two more slots available.

The description says the memory is for MacBook Pro 15.4-inch 2.2GHz/2.4GHz/2.6GHz, and MacBook Pro 17-inch 2.4GHz/2.6GHz.I only have a 20 inch iMac (mid 2007) and am not familiar with all the Macbook models. Sorry can't help you there.

That's what I have. This memory kit made an incredible difference! Just to be safe, click on your apple menu, then "about this Mac". Make sure it says "1333MHz DDR3". You should be good to go. Enjoy

4GB (2X2GB) NEMIX RAM Memory DDR2 800MHz PC2-6400 SODIMM 200 pin for Notebook Laptop Macbook. This is what I got, which worked. I don't see anything about voltage, but if it's not printed on the actual card, you can look up the requirements on Apple.com. Hope that helps. Good luck!

Yes you have a max of 1gig of ddr2 pc5300 per sodimm. Slot and on a early 2006 MacBook Pro that's the max it can handle

From what I can tell this board P4M800PRO-M v2.0 will not support the memory. The key to this memory is the ECC (Error Correction & Checking memory) which is used more for server motherboards. I found that information here http://www.game-debate.com/motherboard/index.php?mot_id=1486&motherboard=ECS%20P4M800PRO-M%20(V2.0). I would not recommend buying this kind of memory for this board.

I think you need:CT3265269 - 2GB DDR2 PC2-5300 Unbuffered NON-ECC 1.8V 256Meg x 64 $35.99 for your Mac. But here is the link to Crucial to verify for your model. http://www.crucial.com/usa/en/?gclid=CP6nxoHd_r4CFQpefgoda0YAaQ&cm_mmc=google-_-us-_-dram-_-null&ef_id=U58PXQAABSyt981O:20140616153805:s

First you need to know what memory your machine has. You look in "about this Mac". This kit is 4 GB 667 MHz DDR2 SDRAM. If your machine uses the 667 MHz DDR2 SDRAM then this memory will work in your machine. The MHz is very important... another brand might have the DDR2 but not the 667 MH. The other thing to know is what the maximum memory allowance is for your machine. Kingston does make a 2GB kit, and it's cheaper.

No, they will not work, they are too fast, etc. (204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM)You want the 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM, look for these here. You have 2 slots, figure out what you have from the system profiler and decide what to buy from there. You have a max capability of 8GB (4 per slot). Hope this helps..... I highly recommend Crucial (in pairs), they have performed perfectly in the last 12+ Macs I have had in 15 or more years.

Their site specifications says it accepts DDR2 and the clock use are using, the1066MHz. Some of the other numbers you posted are for use on Mac computers.

The Ram I purchased was for a mac. Therefore if your system is not a mac I would check carefully. I only work with macs so I don't think I'm the best person to advise.

No, this memory will only work in Servers or Mac Pros. There may be a few other types of boards that will fit it, but those boards MUST support FBDIMM. If your motherboard does not spec Fully Buffered DIMMs, then it will not fit.

4GB (two 2GB SO-DIMMs) of 1066MHz DDR3 SDRAM; supports up to 8GB on the 2.53GHz MacBook Pro(MB991LL/A), according to another user the 1066MHz will work. Good luck, you will be happy with the upgrade.
