Hi! I just made a cpu swap on my asrock p4 combo from socket 478 - 775, the new cpu is the 570J 3.8 ghz 800 mhz fsp 1 mb chache ofcourse i looked at the manual and changed the jumper settings from J1-J21! Now the computer dont start, well it start so long that HD and fans are turned on but no screen, signals from keyboard or pc speaker sounds. just nothing.. what can be the problem? my first thought were bios, but when i checked the cpu support list, the cpu could handle all... (570J 3.8 ghz) http://www.asrock.com/mb/cpu.asp?Model=P4%20Combo

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.)

why not go with a faster MB and CPU combo?
First to awnser your question yes the Pentuim 3.2 will fit the MB as long as yours is a 800 Mhz Bus speed. And the Board can be configured for the proper clock speed. I would also buy a new CPU fan and heatsink greese b4 you install this CPU. Thee are so many cheap CPU MB Combos out there its almost cheaper to just replace both and get a much faster system.

The ONLY thing you got to worry here is the LGA package. The rest wil fall into place and it does support your cpu specs so yes it will indeed work.

Please do be considerate and rate and leave feedback, Thanks

Intel 570J has a clock speed of 3.8Hz and has 800Mhz FSB. It supports DDR SD and DDr2 SD RAM modules. You can get the full specs from here

From ASROCK's web-site:

http://www.asrock.com/mb/overview.asp?Model=P4VM8&s=478

CPU - Socket 478 for Intel® Pentium 4/Celeron processor
- FSB 800/533/400 MHz
- Supports Hyper-Threading Technology
- Prescott support

So, it should work. What CPU did you remove?

Well, there is not many places where you can buy a CPU for that motherboard. Also, you state that the current CPU is 250 MB but I think you mean the system memory is 256 MB. Looks like your CPU is 366 MHZ. You best bet is to look for a Pentium 4 motherboard/CPU and memory combo on ebay. You can probably find a P4 1.6 MHZ for barebones system for under $50.

check your motherboard specifications from the motherboard manufacture website ...
i think your motherboard will not support that processor ..
as you have not given the motherboard i couldnt able to check it ...

if it supports then i think you are wrong some where ....

Hi Rlforeard, yes the BX80546PG3000E is compatible with the motherboard P4I65G.

Here is the list from Asrock. CPU's supported for the Asrock P4I65G board. You will find you can go higher.

Good Luck!

Hi michlionfan, the following link shows what CPU's your Foxconn 661MX board can handel.

From this site, look to the left & find the words, Main Page typed in green. Under these two words is, compatibility. Click on it.

Best wishes!

Try getting a slower cpu, I have a 3.0Ghz P4 with 512mb of ram and it works great, I emailed them about upgrading ram and they said: "Upgrading the memory would not affect the Video card, unless the memory is not compatible with the motherboard, then the computer might not turn on at all."
