Asus SK8N persistant video problem

I've recently purchased an Asus SK8N motherboard to power my AMD FX-51 chip. When I put it all together and fired it up, it kept giving me an error beep - one long, two short - and the monitor would stay on standby.

I have tried 4 different graphics cards, an MX440, geforce 5600 and 5900, and my latest, a Radeon 9800 XT from Asus. None have worked. I have also tried different RAM to no avail.

I have since had the motherboard replaced with a new one, but it gives the same problem. The 'technical experts' at Asus have been no help whatsoever, and have in fact stopped replying to my e-mails asking for assistance.

Has anyone else had this problem and if so, how can I get around it? If not, can anyone suggest any solutions or things that I can try to get it to work? I'm still not 100% sure what the exact problem is, but everything points to a video error.

(^^;(Terrible! What a ****ing Suppot Asus have!)

However, let's put the case in order.

You have had worked the AMD upon your old mobo. (The Former State)

you changed the mother to New Asus with a new registered memory.. (the next state)

two beeps and no display

You exchanged videocards 4times

You changed ram(registered?).

And you changed the new Asusu mother to another new one. (the third state)

The same result?

Are these correct?

Then once get this into the former state.

Tell us its spec. and working condition.

Then change into next state without HDD, CD-ROM, any unnecessary thing. except floppy.

This is the first mobo the chip has been on, my older one being for an Athlon 3000 XP processor. This is the only thing left that can be wrong, hence I am in the process of replace that.

We'll see if that is the real problem!

(^^;?( I can't make out the whole thing yet. But you say the likely criminal must be Athlon itself?)

What about clocking it down?

Not too sure... i'm replacing the motherboard for the second time now, the tech guy reckons my graphics card is actually stuffing up the board. I'm not convinced, but I'll give it a go with another graphics card. Then I'll have to go through the whole process of returning the graphics card!

In the manual it mentions that only 1.5v graphics cards must be used, not 3.3v ones. Problem is I have never seen anywhere where graphics cards show what voltage they are. Could this be an issue (I currently have a Radeon 9800XT and a GeForce 5600)?

I'm having the same problem....help!!

(^^;?(I'm not sure of this voltage, but AGP speed has to have somthing to do with voltage.)

Although I don't think the recent mother can't support Radeon or so, try to change AGP speed in bios.

(^^;?(albzam! In what ways is it the same. I still can't catch hold of even the questioner's condition correctly.)

The problem is, I can't change anything in the bios, as it won't even let me get that far. As soon as I turn the machine on, it beeps and the monitor will not come on. All the tech guys from where I bought it and from Asus keep saying I must use only the certified RAM on their rather small list. This is, in my option, complete rubbish as this is clearly a video fault.

I'm having an SK8V sent out as the suppliers are out of SK8N. I'll see if this makes a difference...

About the voltages: 3.3v was agp 1.0 (2x), 1.5v was agp 2.0 (4x), .8v is agp 3.0 (8x). Most cards are backward compatible at least one version (8x/4x) but either way, none of the cards you've tried would have an issue of voltage.
Can you try some ram from the approved list? (buy and return maybe?) I don't see why it would be the problem, but it could be worth a shot.

karsh, with lower voltages keep coming out, does that mean the new hardware is becoming more efficient with the voltages or just requires less power, or a combo of the two? been curious

Cheers Karsh, didn't think it was a voltage prob. I'm having an SK8V being sent out coz the Company has run out of SK8N, so we'll see if I can get that to work... (still think it is the processor)

Its a result of the ever decreasing size of transistors. Ars Technica has a good article which will give you better understanding. (It doesn't quite directly answer your question, but with the knowledge from the article I'm sure you'll see)

thanks karsh, good article i also understood most of it

I have tried both Motherboards SK8V and SK8N with no luck. I'm using an AMD FX-53 CPU and that is probably the only thing that I haven't change in my testing. I have taking the motherboard back to the store but they couldn't get it to working swaping out different components. The only thing I can think of is that I have to use Registered memory with these motherboards and CPU. I don't know what else to do. Anyone think this will work?

Thanks

I'm sorry, I've been thinking when you said "registered" you meant memory from the approved Asus list. You actually meant you were not using "registered memory", that is, memory with registers on it?
You absolutely need registered memory for that cpu, not ordinary ram.
Sorry for the misunderstanding prolonging things. Hope you get it to work.
