asus cuv4x-e problem

[ratdude747]

does anybody know the value/ polarity of the tantualm (i cant spell tonight) cap right next to the cpu socket? its on the side facing the i/o plate.

it got crushed a long time ago. it still ran but i assume i better fix that if i plan to use it again.

Re: asus cuv4x-e problem

its crushed. a pic would be useless if all that is left is metal paddles.

Re: asus cuv4x-e problem

post a pic anyway.might tell us what it does.most tants and mlcc near the socket are on vcore.probably run ok without it.clear off the remains in case it is shorted.

Re: asus cuv4x-e problem

its right on the socket... crushed when i used a socket a fan with a 3-hole clip... there is like .5 mm between it and the socket. it did run without it. ill clean it off... it will say hi to a lin-lin soon.

Post a pic - for location.
I have an Asus CU-something or other, that was a trade in that I've never even looked at.
Might be similar.

Re: asus cuv4x-e problem

NOTE- i marked out what the original creator of the pic had an arrow to. use the bold arrow on the left instead.

Re: asus cuv4x-e problem

Now that I dug it out. [System was still almost fully assembled.]
It's a CUSL2 Rev:1.02
Doesn't look close enough in the area of your circle to help.
This'n has 7 caps to yurs's 5 and the Toroid is laid down flat instead of standing up.

Re: asus cuv4x-e problem

yeah, th cusl2 is not even close... i have one too... hate the intel chipset in it...

Re: asus cuv4x-e problem

I have a CUV4X-C rev. 1.02 which has more electrolytics around the socket, but nothing like a Tantalum

But seeing it doesn't even have empty an position for an ISA slot, it's probably quite a different PCB assembly

I think you'd be in a minority hating a CUSL2, perhaps one of Asus's last trustworthy products

Re: asus cuv4x-e problem

If it's what i'm looking at, that's not a cap, it's a diode. looks like a flyback diode for the CPU VRM.. I've got a CUV4X-E right in front of me, and the only thing even remotely that close to the CPU socket on that side is D4, which is connected across Q6, a MOSFET in the CPU VRM. The part number on the one here is PJ13 on the top line, and SS12 on the bottom line..

Re: asus cuv4x-e problem

it was black and box shaped. right next to the clip.

edit, the pic was only to show position, that is not my board model. i screwed op.

and yes, gg1978, that is the board you sold me.

Re: asus cuv4x-e problem

ok, its d4.

i had to switch standoffs so while i had it open, i looked.

Re: asus cuv4x-e problem

ill see if its posts tonight... a celeron 400mhz will be sufficient to test with.

[ratdude747]

Re: asus cuv4x-e problem

inconclusive. the fact that its that old made it a no go from the start. ill have to wait for the lin-lin to come in

[pfrcom]

Re: asus cuv4x-e problem

Does it support PPGA processors like Celeron 400 ?

Many boards of similar vintage support only FC-PGA processors

Re: asus cuv4x-e problem

idk. its a pIII coppermine board i plan to put a lin-lin adapter in so i can put a tulatin celeron in it
. its in the mail... waiting for it...

Re: asus cuv4x-e problem

(play taps)

its doesnt like the lin-lin. i bet the lack of diode and a bad cmos battery did it. ill replace it with a socket a board (msi k7t turbo), which will take my ram.
