Thank you for the new download links! Greatly appreciated.

I'm working on an Optiplex 380 and I would like to run a QX9650 SLAN3 C0 10676, is this supported by any Dell BIOS? If not then I would like to use an X5470 E0. There is also a QX9650 SLAWN C1 10677 which I don't own if it makes a difference. I've seen X5460 running at userbenchmark.com in these.

I've seen the Opti 380 running X5460 120W Xeons at userbenchmark.com so the usual 95W Opti limit doesn't apply.
I would like to know if there is a BIOS that will run the QX9650 C0. If I can't get that to run then I will try the Xeon X5470. But I understand that the Xeon BIOS replaces all LGA775 C0 support. So I would like to try the C2X first.

I got the Opti 380 running and tried a few CPUs. The Q6700 ran, but the QX6700/QX6800SLACP wouldn't. This is typical that a 130W CPU won't boot. But The 2 core X6800 75W B2 CPU gave an "incompatible processor found" "startup halted" message. So it looks like there might be a blacklist of some kind. It's kind of sad because even the default 11X266fsb is a nice upgrade. The Q9505S R0 ran beautifully on the A02 BIOS. I'm installing A04 to avoid the digital signing of the A07 BIOS. Didn't find A05. Admin stuck me over here in a Xeon thread but that's not really what I'm doing right now. I would like to have C2X BIOS support if possible.Could this be added to the XEON BIOS mod, or is there something else limiting this computer.
I also played with an E5700 3GHz 800 fsb chip that would be 4GHz@266FSB ,and E7600 11.5x266 that would be 3.8Ghz @ 333fsb. It needs more Voltage to boot the OS but the BIOS kept trying anyway.

It's been confirmed that C2Q Q6600 works in Dell Optiplex 745. Can someone add C2Q Q9400 and C2D E8500 codes for the 745?

 The 745 only runs 65nm CPUs. The best option there is the QX6800 SLACP. The base clock 2.93GHz 11x266 is the fastest there is. Throttlestop 6.00 software can control Voltage and multiplier. Heatsink the VRM MOSFETs (there are only 6), and expect about 3.45GHz 13x266. The steps are whole multipliers and 3.72 GHz is a step too far for the 3 phase VRM. D9729 is a heatpipe cooler that fits. T9303 is better but you must mod the cover. if you believe in single core performance then the X6800 can go 3,72GHz but it's a much older stepping and runs as hot as the Quad.
 If you have the Tower version of course. The 305W PSU will power a Zotac GTX 1050 2GB Mini (not low profile). The 4GB Ti is a stretch for an 8GB RAM machine.
 this is the only 1080p card that fit's without modification. Maybe some low profile GTX750 Ti with the tall bracket, but they cost just as much.
 Performance will about equal a Q9650 3 Ghz. give or take a little. At userbenchmark.com CPU and GPU scores will be in the 38-41% range.

I'll look into the QX6800. I have some heatsinks already. I also have the tower cooler with 6 heat pipes, and I've already replaced the power supply with a 450W noname and installed an HD 7950.

Also, I ran the 1050Ti 4GB in a rig with an i5 3330 and 8GB of DDR3, it ran great. 8GB of RAM is still more than enough for games like Fallout 4, the most I saw was 6.5GB in Diamond City.

I'm currently running an E6420 with the BSEL mod to 2.93GHz.

Will the 745 handle a 1600MHz FSB? because I can amp it up to 3.16GHz or so that way and that's more than enough performance for DDR2.

Speaking of Optiplexes, what about the 760, what are the limits on that? I've got the heatsink with the copper base and thick steel fins, not the all-aluminum one that came with the GX series.

I've also disassembled the chassis by removing all of the plastic panels, painted the entire chassis semi-gloss black, then painted the front and rear bezels a nice red and installed a red LED fan in place of the black 120mm front fan. I also plan on installing a Noctua slim 92mm fan on the rear grille after I solder pins onto the missing HDD fan pads.

Hi I have a Dell Optiplex 380 and I have a Xeon E5450 SLBBM E0. When I try to use the the patches above the task fails according to The TaskResult.xml. Am I doing this right or do I have to do it a certain way?

 The Opti 745 having support for 1333fsb is good news. I didn't try it because i already had the QX6800, and the faster E520. I don't think 1600 FSB is going to happen. Very few chipsets support that (X38,X48).
As far as the Opti 760 goes, it has a 95W CPU limit, and no 771 Xeon support. So Q9650 is about it. The 780 MB is identical with 16GB DDR3 support.
SetFSB will get you a small overclock. With heatsinks on the VRM MOSFETs, and a VID pinmod who knows. The Q9505S is a 65W Quad core and might have some headroom for an overclock on the 95W motherboard.
