I thought it could be a problem with the cable (shorting PSU or something), but I tried another and the same happens. :(

prob a problem with the adaptor, try another adaptor

Stocky,

Check the socket on the MB to make sure it is clean
Check the pins on the CT-479 to make sure it is straight
Check the socket on the CT-479 to make sure it is clean
Check the CT-479 to make sure there are no blown chips or burnt / scorch marks
Check the pins on the CPU to make sure it is straight

I think there is a short between your cpu -> adapter -> MB cuz it would power down so fast. Or a blown adapter.

When my CT-479 blew a chip, my cpu fan still spun but got a blank screen and the MB was telling me there was a cpu error (P4C800ED with voice warnings turned on).

This happened to me twice last night - I was testing some other 770s and tried to boot after installing one. Got the fans on for a sec then nothing......I had not tightened the little screw that locks the CPU into the adapter socket. You must make sure this goes all the way round to the locked position.
2nd time I had 7 volted a 120mm fan, it didn't like that either, must be the type of fan (LED) causing problem as I have 7 volted many fans before. Anyway put it back to 12v and it booted fine.

if i remeber a dead cpu is the same as not having the power lead connected to the ct-479 fans spin but no post.
i had a problem like yours the fans would spin for a sec and then top but that was a faulty crystal orb fan on a vga card but if it works ok with a p4 and nothing else changed it wont be anything like that.

have you tried just the vga card , ram and cpu in case it's some thing else connected that does not like working with the ct-479.

also do you have a speaker connected does it beep in any way.

I have a question: can you overclock a Dothan in a ct-479 in a P4C800-E deluxe just with the BIOS settings? I see people use Windows tools to clock and volt them, I wonder whether you have to use them.

You can do it the way you like. With the latest bios you get vcore upto 1.6 multipliers and fsb... Its just like old-school northwood overclocking - with the multis :toast:

You can usually squeeze around 50mhz more benchable if you use clockgen.

50 millihertz ain't worth the trouble http://www.cons.org/smileys/wink.gif.

I don't use Windows hence the question.

When the power lead to the Ct-479 is plugged in and I press the power button the fans just spin for a second, then dead. Without it the fans continue spinning but the monitor stays blank. Has anyone experienced this before?

Any ideas what it could be - could it be a dead CPU? :(

I experienced the same with my 730. Blank screen. No signal at all. I think the cpu is dead. :( I removed the heatsink and turned the PC on. The cpu doesn't even get warm. The system runs just fine with a P4. I tried a new CT479 but nothing changed. I'm waiting for a new 740. :brick:

Buddy,

Your CT-479 is dead. Your CPU is fine.

I have the same problem on one of my two Dothan desktops.

Hello to everobody from noob on the forum by the way.

NoX,

Your CPU is most probably fine. It is your CT-479 that has a problem. Seems like those adaptors are really easy to short.

well if your cpu isn't getting warm it could either be the cpu or the adapter. the adapter is cheaper so replace that 1st.

just something for me to think about if i get some decent ram for my dothan setup. :cool:

boot at 201 and up with clockgen.
Ram are Kingston DW-50 ;)

My 730 was a gem, 2.8G at 1.510V. Stock HSF :(

Sweet memory! What voltage are you running that at?

Booting at 201MHz is a NO GO....... ;)

You HAVE to boot at 200MHz so as to see some real gain........ :)

True, but it's really heavy on the board!
boot @ 201 we can reach ~265 Full PAT
boot @ 200 max is ~240, but the numbers are better for sure!

It's not "full PAT".......It's some kind of "phseudo PAT".........You loose a LOT by booting at 201MHz.......Almost 1sec in Super-Pi....... ;)

ALSO Rams at 270MHz by booting at 201MHz, do worse than 240MHz by booting at 200MHz......

NoX,

I am sorry. I had the same problem you described, then switched adaptors and all my CPU's turned out to be all right. Waiting for a new CT479.

There seems to be a lot of different PAT levels... CTIAW reports full PAT when booting at 201, but as you say, you gain even more when booting at 200.

Problem is, I need 250+ with ATI card (no lock at 200), and my board can't handle more than 240 with 200-boot. Maybe you have some advice :)

how do you raise your vdimm, by vdimm mod or booster. I have problems with ram, did anybody experiance some kind of trouble with vdimm, cause that is right now the only thing i can think of, that could be the problem.
