USB Power Issue with ASRock K8 Combo m/b

I have recently inherited an ASRock K8 Combo m/b. With Athlon 64 3000+ (Socket 754). I have installed XP Pro Sp2. Everything goes OK untill I try to install a USB device that requires system power. On installing the device, the system just powers off, until the USB lead is removed. If I install a USB device that has it's own power, I don't get this issue. I'm running a 550w EZcool PSU. Any ideas?

How can I buy AM2 cpu board to modernysed motherboard K8 upgrade NF3?

You don't Socket 754 and 939 are dead ends with no upgrades. Most AM2+ CPU'S will work on on current AM3+ motherboards as long as they support DDR3, but anything AM2 or below is no longer supported.

What does code 7f mean on kv8 pro

Did you ever resolve?

This is the board with the external OC monitoring panel, right?! I owned this, too. I had a similar KV8 board from Soltek, as well--post codes, also. My Abit died several years ago.

The ABit's manual still exists online. According to the code, It's hanging on the onscreen logo--it says to switch to text. Here's the page describing your code:

If I remember correctly, that's not a serious error code--popped up often after new installs.

If it's a hard drive error--do you have the master/slave configuration jumpers correct? (Hard drive vs. Optical drive? Probably, you want the hard drive as master--optical as slave)

Is cable orientation (Pin 1--from PATA cable and at drive(s)/board) correct? Perhaps I remember now--maybe the BIOS can't get to the hard drive and OS.

Is your floppy light always illuminated (it shouldn't be)--is that cable installed correctly?

If your onboard hdd controller is dead--and, you worked with AGP over the years--you likely have a PCI card that will take its place. (If not, you may purchase that pretty easily. still.) Syba, Siig, Sabrent, StarTech, etc.

If your controller is OK, have you tried running a live i386 (32-bit) or AMD 64(64-bit) Linux disk or an old Bios upgrade/DOS floppy--to see if you get some type of OS posts? Is your proc 64-bit or 32-bit?: If I remember correctly, 754 CPUs generally were 64-bit--some were 32-bit, though (I still own one of those, too).

Did you clear your CMOS first (move the jumper for a few seconds and back)? Is the jumper correctly installed now?

Ah, the days of socket 754 (I never obtained Socket 939.....) Socket 754 still is a good value--you may obtain such a proc for about $5 on Ebay. (Used boards are a little pricey--considering.) I get the sense that 754 was the business board--939 was the gamer board.

Recently, I resurrected my old Shuttle Athlon XP board--considering its age, it holds up pretty well. Works fine with 32-bit Linux Debian distros. Dual-channel. Great OC board in its day. Currently, I have a 9800XL card in--soon, I'll put in a 3850 AGP....

AsRock Support > AlivenF6G-DVI Motherboard > Main Support page,

In the list on the left hand side, click on CPU Support List

The AMD Athlon 64 X2 5800+ CPU, (Processor), is part number ADA5800IAA5DO.
Operates Up To a maximum frequency rate ('Speed'), of 3.0GigaHertz, has two L2 cache's of 512MegaByte, and uses the Socket AM2 CPU socket.

In the CPU Support :List it is not shown.
This is ONLY because the Athlon 64 X2 5800+, came out way after the CPU Support List was compiled. NOT because it isn't supported.

No, I have to amend that,

It's because AMD's lack of information, apparently, that AsRock didn't list it.

I don't see the voltage range listed anywhere. (To include AMD)

At any rate let's go with deductive reasoning, and see if this CPU is supported.

1) You can compare the Athlon 64 X2 5800+, to the other CPU's in the CPU Support List; that are comparable to it, and above it.

Don't even have to go too far.
Look at the ADA6000IAA6CZ, and the ADX6000IAA6CZ CPU's.

The two Athlon 64 X2 6000+ versions.
(Doesn't state that, just the above part numbers)

However I DO notice that the ADX requires BIOS version P2.00, and the ADA only requires BIOS version P1.60
(Since BIOS)

2) The motherboard chipset is an Nvidia GeForce 6100 and Nvidia nForce 430, Or Nvidia GeForce 6150SE and Nvidia nForce 430

Compatible? Yes.
May need the P2.00 BIOS update, if not already installed.

ASROCK K8 Combo Z When I turn on there is no POST no beeps. Fans om Mobo and on graphics card spin but nothing else happens. I can not even turn off using the computer on switch I have to turn on at the...

Hi c_j_quinn,

There could be many things that could stop the board from turning on, Determining if it works is like detective work. What I do, is take everything off the board to start. Then add the minimum to start a board to see if it will start. That's one drive (cd or otherwise) the CPU, and one bank of memory. (that's not a required eliminate, but it helps avoid beep codes) Also, make sure you have your pin's set on the board absolutely correct, or that could be your problem to begin with. Now, you should get the power supply on, and the cpu. If those don't power up, it's then either one of the five elements. The CPU, Power supply, Ram, Drive, or the motherboard. The next step is to replace each one of the first four to see if you get any change. If no change, then I usually get another board that I can test the first four, and make sure that they work. After that, then I say you have a DOA Board

Good Luck
