Need Help. Upgraded processor -- does not post - (not yet resolved)

[ricwhite]

I popped a AMD XP 3000+ in my computer and now I get nothing but a blank screen. I don't hear the boot "beep" from the computer either. The computer "runs" but no images at all. Can't even get into bios. Monitor doesn't "boot" but stays in stand by mode.

Before I upgraded, I updated the bios on the A7N8X from a version 1001.G to a 1008. The unstall of the 2100 and the install of the 3000+ went smoothly without a hitch.

Am I missing something?

All I get is a black screen. The internet guides seemed to indicate this was an "easy" upgrade that should cause no problems.

Any help would be appreciated.

Try and clear the motherboard of electricity and try it again...

1. Unplug the PSU cable connecting to power outlet.
2. Unplug 24 or 20 pin along with 4pin 12v (square).
3. Press the reset and power buttons repeatedly for a couple times.
4. Put everything back
5. Hope it works.

Unfortunately, it doesn't

Any other ideas. As I mentioned, the computer "powers" but there is no boot "beep" and the monitor stays in standby and the mouse, keyboard don't work. There is absolutely no images on the screen. However, the hard-drive lights up as if loading and then, after a minute, goes off. But the screen stays blank. Attached a different monitor without luck.

I put back in my AMD XP 2100+ and my computer works flawlessly.

I bought this AMD XP 3000+ (model AXDA3000DKV4D) on Ebay. Does this sound DOA to you? Or is there something I'm doing wrong. From all that I've read, it should be a drop in and boot upgrade. I'm emailing the seller later today. Thanks for your help.

Does your motherboard support the FSB speed of the 3000? I think 2100s ran at 266. It is possible your mobo does not support speeds faster than this. I believe all 3000s were either a 333 or 400 FSB, depending on which core you have. If your new cpu is an athlon mp this would not be an issue, as they all run at 266.

My MB FBS can be:

100
133
166
200

But I'm in "duel channel" mode. So I'm currently running 133mhz x 2 = 266 mhz.

The XP 3000+ runs at 166 mhz x 2 (duel channel) for 333 mhz.

According to the Asus website, my A8N7X Motherboard should work up through AMD XP 3200+ processors.

So, I don't know why this XP 3000+ is not working.

do u mean A7N8X?

Yes, sorry. And, yes, I have cleared the CMOS. And, yes, I have a good heatsinkand fan and used good thermal compound. And, yes, it still doesn't work.

Ebay seller tells me it's my computer and not the processor. So, I'm counting on the experts here to help me solve this.

 

[SonicIce]

this is probably more work than its worth but, you could try your old cpu and see if it still works that way.

 

[Big Lar]

He stated above that his original cpu still works.
Coupla things come to mind, first off, are you sure your PSU is up to snuff for the additional load of the new cpu?

Have you tried reseating the cpu, as well as checking that the fan header is attached properly?

You could try booting with just 1 stick of ram just to rule that out, but it seems unlikely.

Is there a shop near you, that you can take the chip to, to have it tested for functionality?

Thats about it, only other thing I can think of, would be something shorting out somewhere.

Thanks for your response:

1) Yes, I have tried reseating the CPU, but it is really a simple "slip-in" process. Not much there to re-try.

2) Fan header is attached. Fan works well.

3) I did try only 1 stick of RAM. It made no difference.

4) My PSU is a very good 450 watt one -- just upgraded in the last year when I got my new video card.

Thanks for the ideas. Let me know if you can think of anything else.

 

[Big Lar]

I'll give it some thought, but that usually about covers it. At this point, I am hoping the Ebay'r gave you some kind of Guarantee of non doa, because it sure appears to be dead.

Have you looked closely on the bottom of the cpu, for bent, and or missing pins? Thats all I can think of right now, sorry

Larry

Review

Specs: A7N8X Motherboard
Old Processor: AMD XP 2100+
Memory: 2.5 g DDR400 (PC3200)
PCB: 1.04 Bios: 1008
Power Supply 450 watts
Video Card: Radeon X850XT

New Processor: AMD XP 3000+

Preparation: Flashed bios from 1001.G to 1008. Cleared CMOS. Uninstalled old heatsink/fan and then processor.

Installation: Installed new XP 3000+ processor. Put on thermal grease. Installed new heatsink and fan. Re-connected all cables.

Problem: Fans start. HD light comes on. No boot "beep" Monitor stays in standby, no keyboard or mouse capability. Computer never boots. Cannot "delete" into bios.

Tried: Clearing CMOS again. Reinstalling XP 3000+ processor again. Reinstalling old XP 2100+ processor to check systems (everything worked with old processor.) Re-installed XP 3000+ again. No luck

Cleared CMOS again. Took out memory. Tried three different brands of DDR400. No luck with any of them.

Disconnected components except for the very basics. No luck

Completely removed the video card. No luck

Inspected and reinstalled the XP 3000+ processor again. No luck

I'm running out of ideas. The seller of the processor claims that if the fans blow, the CPU is good and the problem has to be with my computer or settings. Hmmm...

Keep the good ideas coming. I'm sure there IS a solution out there. I'm leaning toward a bad CPU, however.

 

[ricwhite]

I'm gathering this is an unresolvable issue and likely a bad CPU. I'm preparing to contact the seller. Is there anything else I should try first? Thanks

 

[ricwhite]

Sending the processor back to the seller. He claims the CPU worked perfectly before being shipping and that they will test it when they get it back and determine whether I get my money back or not. If they determine the processor works, they will not refund the money.

 

[3chordcharlie]

GL, it's easy for ebay sellers to hide behind 'incompatibility' (even when it's not incompatible), the only dead cpu I bought from an ebayer, they took back, 'tested' claimed it worked and sent it back to me; eventually the cost of shipping made it not worth pursuing (nevermind that the system I was testing with was running the exact same chip, same stepping, from the same seller!).

I hope your seller is more honest than the one I dealt with.

 

[funmilayo]

I'm having the same problem, but with an xp 3200+.
The seller gave me the same line almost word-for-word. Very rude. Unfortunately I made the transaction outside of ebay, so have little recourse if they claim it still works. At least you can leave negative feedback or fraud report if necessary.

 

[Big Lar]

How's about contacting another member here close to you, and seeing if they will test the cpu in thier board? That would tell the tale for sure.

 

[imported_redlotus]

I know this might be a little late, but if not, there is one more thing that I might try.

With the 2100+ installed, set the FSB and and multiplier manually in your BIOS. Then install the 3000+. Yes, this will underclock the new proc, but it would verify whether or not your mobo is detecting the CPU correctly and the 3000+ shouldn't have any problem running underclocked.

I know it's a long shot here, but it'd be one of the things that I'd try.

From everything I've read, your CPU should work. I've run four of those boards with everything from Tbirds, to the 3200+ Barton chips.

If you have no beep, or even any error beeps, it sounds like the CPU is dead. If there was an error other then the CPU, you'd likely get some type of error beep. Or the BIOS would automatically restart the computer, underclock everything, and start the computer hardware safe mode.

 

[ricwhite]

Sent the processor (AMD XP 3000+ 333fsp barton) back to the ebay seller. He said he tested it and it works just fine. He said it was my motherboard (A7N8X vs. 1.04 bios 1008) or my memory that is causing it not to post. I replied that it's not my memory because I tried a "bare" boot with miminal components and basic memory (including kingston, crucial, and muskin). Plus, a memory problem would still post. This processor is not posting at all or beeping any code.

It can't be my MB since I have a A7N8X ver. 1.04 bios 1008 which can support up to XP 3200 400fsb. Yes, I have cleared the CMOS before installation.

So, am I just being fed a line? The seller claims to be sending me a "different" processor. I guess I try that when I get it. This guy has 167 positive feedback at 100%, so it's odd that he's lying to me.

Any advice on what to try when I get the new processor that I already haven't tried.

Thanks

If swapping back to the old CPU and the system works great, then it was a problem with the CPU. That motherboard should work with the new CPU and being an Asus, if the CPU is set wrong in BIOS causing it to not POST, then second try at POSTing will result in the system turning on in "safe mode" meaning the CPU is set to lowest possible parameters and the system will boot directly into BIOS. If it doesn't do that with the "new" CPU but works fine with old, dead CPU is what I'd say.
