I am worried about the PSU, post the info on the PSU label. How many amps are available on these rails(+12v, +5v & +3.3v)?

I'm confused. In your other "deleted" post you say you have an ASUS motherboard, 8800GT, and a case. Are we working with that stuff or are we working with the DC7800P mini tower.

What about the processor? The stock one, an E8500, or a Q9300 or something else?

500w doesn't tell us anything either. Answer the question kuwese asked in #1. We need to know how many amps on each rail. Is the the original psu or some other power supply you've bought?

Wasn't clear to me.

PSU is good. Rest of your machine is as manufactured?

What is exact model number? I want to try and track down motherboard in your rig.

PSU is good but it has 2 12 V rails but it should be enough for the card mentioned above. According to this link http://h10010.www1.hp.com/wwpc/ca/e...
the board has 4 DIMMS and they say that its expandible up to 8GB DDR2
they did not mention ram speeds if u can give us the motherboard make and model we can tell u the pcie and ram speeds which are supported

I posted this link on your first thread but u didn't bother to check it, so i'm posting it again
http://h20000.www2.hp.com/bizsuppor...

From the link, look at description u can see all three form factors of HP Compaq dc7800, yours is Convertible Minitower, scroll down to Memory and u can see supported memory with their speed.

Now what PCI is it? 2.0 or 2.1 ?
The Intel chipset Q35 was released back in June 2007 and PCIe 2.0 was released back in January 2007 so it must be PCIe 2.0. Don't worry the HD 6570 is PCIe 2.1 card and it works even with older PCIe 1.0a slot.

The other is in use for video editing.
I think u talking about your other system(the one with 8800GT and ASUS board)
Video editing rely heavily on CPU, u need a high end CPU for the that task. Also the old 8800GT isn't enough for video editing

They may be right but my money is on HP website.
The problem of DDR2 1066 is the voltage, as i said earlier most of DDR2 1066 are factory overclocked (normal voltage for DDR2 is 1.8, factory OCed is 2.0 - 2.2v which may not be supported by your system).

sticking with the 800 Not a big difference in 800 and 1066
When dealing with FSB don't get the fastest memory supported by motherboard, look first at FSB then get the memory. U are not going to benefit from DDR2 800 or 1066 but you are going to benefit from DDR2 667 because core 2 duo E6550 is a 1333 FSB CPU. Since u can't adjust memory clock in OEM BIOS get DDR2 667.

Intel Q9300 is also a 1333 FSB chip.

1333/4=?
667/2=?
333=333
or 1=1 (1:1)

As kuwese wrote before...

"Since u can't adjust memory clock in OEM BIOS get DDR2 667."

Period.
