One more issue: there is no startup chime! Tried turning it off and on many different times trying some potential solutions out and not once was there a startup chime. So since the keyboard can't be recognized I am unable to boot from a CD, or anything else for that matter. But how did the CD/DVD drive work? It spun up when I turned the machine on. I tried all 5 USB ports on the machine and none of them worked. When I plugged in my Apple USB keyboard, I decided to press the caps lock key and see if it would light up green. I also tried booting up from a Snow Leopard disc (there isn't any internal CD/DVD drive, so I've been using an external CD/DVD drive). I guess it's good that the CPU lights aren't lighting up, but what about the the GPU and POWER lights? Shouldn't those be lighting up too? Out of all the lights, the ones that do light up are the TRICKLE light and the EFI light.

My first thought was that maybe the logic board wasn't getting enough power, but I have no idea on how to check this as almost everything besides the RAM risers and the extension slots are covered by something.Īnother problem I found is that some of the diagnostic LEDs that should be lighting up, aren't.
A light tug from both ends on both cables assures that these cables are not going anywhere soon, and I doubt that there would be such a heating issue as soon as I press the power button, especially since all the fans are running fine. Note that a) both power cables are in both power slots and hooked in securely and b) these lights turn on immediately after pressing the power button. After some searching around on Google for a little while and sifting through forum after forum, they all seemed to agree upon the fact that these lights were from the two internal power cables (D1602 and D1603) not being plugged in and that there was a critical temperature error (D1601). The ones that light up are D1601, D1602, and D1603 the other one, D603, does not light up. The video card, after the machine is turned on, has three of the four diagnostic LEDs lighted. I'll just have to assume for now that it works. I have tried the DVI cord and the monitor on two different machines and they both work perfectly fine, and now I have no other Mac available to test the video card on. The reason I'm posting here is because the darn thing will not "boot." The machine starts up fine (HDDs spin up, lights on the RAM risers illuminate momentarily, etc.), but there is no output out of either of the DVI ports. (I bought the HD4870 later after I found that the one that came with it, an ATI X1900 XT, was part of a recall Plus, the fans on the X1900 were revving up REALLY loud.)

It also has 2 Gigabit Ethernet, 5 USB 2.0 ports, 2 Firewire 400 ports, 2 Firewire 800 ports and optical digital audio in/out, Bluetooth 2.0+EDR, AirPort Extreme (802.11g/n) with a modem option.Hey everyone! So, I recently got this Mac Pro (Model number A1186, EMC 2113) with two Quad Core 2.66 GHz Intel Xeon 5150 processors, 16GB of RAM (both RAM riser slots completely filled with 4x2GB sticks of 667MHz DDR2 ECC FB-DIMM each), 2x1TB clean HDDs, and an ATI Radeon HD4870 (512MB DDR5 memory) video card with 2 DVI ports and an S-video port.

These models also came with a 7200 RPM 250GB 3GB/s SATA hard drive, a double-layer 16X "SuperDrive" plus an NVIDIA GeForce 7300 GT video card with 256MB of GDDR2 SDRAM, 1 dual-link DVI port and 1 single-link DVI port.Įxpansion is where these models shine with 8 memory slots, each accepting up to 4GB per slot, yielding 32GB possible maximum. The FBDIMM spec for these models includes large fully finned aluminum heat sinks to provide superior cooling. The base factory configuration is 1.0GB DDR2-667 (PC2-5300) ECC "fully-buffered" FB-DIMM memory.
Other variants of this model offered were Dual 2GHz Dual Core Xeon 5130, Dual 3GHz Dual Core Xeon 5160, or starting and Dual 3GHz Quad Core Xeon X5365 (Clovertown) versions. The model Mac Pro quad core 2.66 (Gen 1) gets it's heartbeat from two 2.66GHz dual core Intel Xeon 5150 processors with 4MB of shared level 2 cache per processor, a 128-bit SSE3 vector engine and 1.33GHz 64bit dual frontside buses.
