Where you processor

The motherboard for the dc7600 has an Intel LGA775 processor socket. However, not all LGA775 processors are compatible with the motherboard. For the small form factor, the following CPUs are supported: Intel Celeron D Processors:
Intel Celeron D 331 Processor (2.66-GHz, 256K L2 cache, 533-MHz FSB) , Intel Celeron D 336 Processor (2.80-GHz, 256K L2 cache, 533-MHz FSB) , Intel Celeron D 346 Processor (3.06-GHz, 256K L2 cache, 533-MHz FSB)
Intel Pentium 4 Processors with HT Technology:
Intel Pentium 4 521 Processor (2.8-GHz, 1-MB L2 cache, 800-MHz FSB) , Intel Pentium 4 524 Processor (3.06-GHz, 1-MB L2 cache, 533-MHz FSB) , Intel Pentium 4 541 Processor (3.2-GHz, 1-MB L2 cache, 800-MHz FSB), Intel Pentium 4 620 Processor (2.8-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 630 Processor (3.0-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 631 Processor (3.0-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 640 Processor (3.2-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 641 Processor (3.2-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 650 Processor (3.4-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 651 Processor (3.4-GHz, 2-MB L2 cache, 800-MHz FSB), Intel Pentium 4 661 Processor (3.6-GHz, 2-MB L2 cache, 800-MHz FSB) or
Intel Pentium D Dual Core Processors:
Intel Pentium D 805 Dual Core Processor (2.66-GHz, 2x1MB L2 cache, 533-MHz FSB), Intel Pentium D 820 Dual Core Processor (2.8-GHz, 2x1MB L2 cache, 800-MHz FSB), Intel Pentium D 915 Dual Core Processor (2.8-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 925 Dual Core Processor (3.0-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 930 Dual Core Processor (3.0-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 940 Dual Core Processor (3.2-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 945 Dual Core Processor (3.4-GHz, 2x2MB L2 cache, 800-MHz FSB), Intel Pentium D 950 Dual Core Processor (3.4-GHz, 2x2MB L2 cache, 800 MHz FSB)

Unfortunately, these are old processors and I don't see any available new. Newegg.com lists a couple available as refurbished. You may be better off getting a new computer with either a Intel I3 or current AMD processor.

I wish that I had better news for you.

(do not attempt to use a CPU that your motherboard doesn't support. It probably won't boot.)

Type of RAM supported has nothing to do with the processor make & type in most cases. It is more important to verify that the motherboard supports this kind of RAM.
In general, most motherboards supporting the Intel Pentium 4 2.0 GHz processor support also DDR1 RAM.

Depends on the socket type.. Socket 423 and 478 do not support core duo or quad core processor types. However, if you have LGA 775 (aka socket T) your motherboard will support the following:
Intel Pentium 4 (2.60 - 3.80 GHz)
Intel Celeron D (2.53 - 3.60 GHz )
Intel Pentium 4 Extreme Edition (3.20 - 3.73 GHz)
Intel Pentium D (2.66 - 3.60 GHz)
Pentium Extreme Edition (3.20 - 3.73 GHz)
Pentium Dual-Core (1.40 - 3.33 GHz)
Intel Core 2 Duo (1.60 - 3.33 GHz)
Intel Core 2 Extreme (2.66 - 3.20 GHz)
Intel Core 2 Quad (2.33 - 3.00 GHz)
Intel Xeon (1.86-3.40 GHz)
Intel Celeron (1.60 - 2.40 GHz)

hi,

you can on this motherboard models for your intel Pentium 4 processor,
1. ASUS P4P800 Deluxe
2.MSI Neo2-FIS2R
3.ASUS P4C800 Deluxe
4.Intel D865PERL
5. ABIT IS7

1.*********** Board not supporting Your Processor.
2. Try With Lower Speed Processor
3. Mahe sure that Mother Board is Working or Faulty.
4.Check the ram twice

If it HELPS RATE ME!

You can find supported processors at http://processormatch.intel.com/COMPDB/default.aspx

Also, these processors are supported on your motherboard:
Intel® Pentium® D,
Intel® Pentium® 4,
Celeron®,
Celeron® D processor

I suggest this is not going to work.
1.Your motherboard is supplying 1.75 DC volts of electricity to the processor socket.
You have installed either a SSpec number SL68Q, or SL62P,
Intel Pentium 4 processor. (The sSpec number is on the top of the processor case)

These Intel Pentium 4 processors use 1.425 to 1.525 DC volts of electricity. If you haven't already, you are going to burn this processor up.

Also, the Intel Pentium 4 that you had before, is based on the Willamette Core. (180nm) These earlier Pentium 4's did not have HT.
Hyperthreading Technology.

The Intel Pentium 4 you have in it now, is based on the Northwood Core. (130nm) These Pentium 4's come with HT.

Even if you could go into your BIOS Setup utility, and change the CPU voltage, and lower it, the HT in the processor you have now, wouldn't work on this motherboard.
(CPU stands for Central Processing Unit. Another name is Microprocessor, or simply -> Processor)

You won't be able to lower the voltage in BIOS Setup, for this processor. IF you did, then you would change the Front Bus Speed, and the ram memory wouldn't work.

Solution?
Obtain an Intel Pentium 4 processor, that uses the Socket 478 processor socket, has a 400MHz FSB, and is based on the Willamette Core.

Here is a list of Willamette Core, Intel Pentium 4 Microprocessors, that will work,
