    RAM for Mac Pro

    So I got a 2006 Mac Pro running OS X 10.6, with a 20" Apple Cinema Display.
    I have a question: I noticed it uses "FB-DIMMS" I'm assuming that means they are Fully Bufferred ECC... can I use completely normal DDR2? Because it's got 2 empty slots and I've got 2 1GB sticks of DDR2 800 Wintec AMPO RAM with heatsinks that I want to put in... can I do that? Will the Mac Pro take normal PC RAM?
    Because I really rather not buy more RAM for it!
    Thanks!

    PS: If I DO need to buy some RAM, would any/either of the following work?

    One more thing: would these work in it? http://www.ebay.com/itm/MATCHED-PAIR...item2ebed5ac5c

      have you tried? the notches shouldn't even line up between FB DDR2 and Non FB DDR2

          FB-DIMMS are Fully Buffered ECC. So no you can not use normal DDR2. Also the memory gets very hot in those machines that is why apple uses the massive heatspeaders they do on the memory. I do not think a normal heatspreader would keep the memory cool enough but it may, just dont have a cow when you fry the ram if you didn't use the proper heatspreader. The memory also has to be installed in pairs as well if I remember right.

              If you want stuff with the heat spreaders the size of an apple, then this looks good. Otherwise, you could see if you can get a fan in there.
              I love putting bad caps and flat batteries in fire and watching them explode!!

                  I offered the top link in the top post $100.00. If he doesn't take that offer I'll look at the others.

                  c_hegge, as far as cooling the RAM, here's how it works:
                  Front intake vent-->Front CPU fan-->CPU heatsinks-->RAM-->Rear exhaust fan-->Rear exhaust vent
                  No shortage of RAM cooling

                      Unfortunately you are right My normal DDR2 RAM won't even fit, lol

                          Hi,
                          Have a Macbook A2179 with liquid damage. Customer showed it some shop which has done an ultrasonic cleaning of the board.
                          The board pulls 0V but doesnt turn on. No Fan SPIN. NOT IN DFU.

                          I checked the Power Sequences below and found this -


                          Once a valid external power source (Charger or battery) is connected, the following rails will come online.
                          PPBUS_G3H: Normal voltage is ~12.6v on the charger with the battery disconnected. Produced from the ISL9240 (U7000, which uses PPDCIN_G3H as its VIN.

                          FAST MODE vs NORMAL MODE

                          I have recently acquired a HP 6632A DC power supply. I am just beginning to use it and I have been reading the manuals for it. It is the first power supply I have ever owned or used. I am a very beginner hobbyist and do not have an engineering background, as may be obvious by my question...

                          I can't seem to understand what the actual use is for the 'Fast Mode' or the 'Normal Mode' on the power supply. Although the manual states what the two modes do from a engineering/technical standpoint, I don't know enough to understand what it all means,...

                          Lenovo Thinkpad E14 Gen3 stuck on "To interrupt normal startup, press Enter" screen
                          by BMCappelletti
                          Hi everyone.
                          Lenovo Thinkpad E14 Gen 3, stuck on the "To interrupt normal startup, press Enter" screen.
                          Found a lot of people with this issue, but with no definitive answer. Some people managed to get away accessing BIOS, going to Startup and turning off "Option Key Display". For me that only removed the interrupt normal start up message, leaving only the Lenovo logo.
                          Most people say hitting Enter does not work. It's true, if you wait a few seconds. But if you hit Enter right away you get the options to enter BIOS (which works), run diagnostics (goes to a...

                          MOSFET? Is its voltage reading normal?

                          Hello, guys!
                          Got this 8-pin MOSFET (I presume) on the motherboard that I'm still trying to repair (HP Stream 11-ah117wm DAY0HGMB6C1 REV:C), close to the DC IN connector, and when I read voltage on Drain (5-8 pins) and Source (1-3 pins), I got the 19.81 VDC of the DC IN on each, but on the Gate (pin 4) it's 25 VDC. Is it normal? Now, I'm not quite sure the component is a MOSFET, but it looks like, and since it has the printed code on it totally unreadable, I can't try to find the datasheet. Can anyone give me a hand on this? Or maybe ff there's some MOSFET tutorial or something that you can...

                          Asus FX507MP P3V3AL 484 ohm, is normal?
                          by Dcortest
                          Hello,

                          I'm trying to repair an Asus FX507MP that is nor turning on. It has several faulty components on 5v and 3v3 rail, but now after desoldering several power switch from P5V0AL I have 1,6kohm (waiting for the replacements to resolder the new ones).
                          But on rail P3V3AL and VRB_VDD3 after desoldering 4 drmos from the GPU i'm having 484ohms could it be a normal value for this rail? injecting 1v only has 0.005A current consuming.
                          I opened the jumpers from the 3V-5V converter to isolate the load section to diagnose (also opened the P3V3A bridge)...
