Problems with 1.2Ghz Tbird Upgrade...

[gyoung]

I'm having a little trouble with upgrading my Duron 600 to the new 1.2Ghz Tbird I just got last week.

I replaced the Duron with the 1.2Ghz CPU and started it up. I didn't get anything. The monitor stays in standby mode and I can't get anything.

Any ideas?

Do I have to set the BIOS to anything special? Should I remove the BIOS battery so it resets to the default then insert the new CPU. I put the Duron back in and everything works fine.

[gyoung]

Oh yeah, I have the KT7-RAID motherboard. The new Tbird is the 1.2Ghz 200fsb variety.

[Jeffy]

r u using jumpers b4 to set your duron or auto detect core n voltage?

[gyoung]

I think I'm using auto-detect.

I went ahead and cleared the CMOS before I installed the processor. I may have to see if the processor is still alive.

That was my initial thought, was that the cpumight be a goner. Try the Duron again and see what you get. If you reset the CMOS, everything should be ok (set to autodetect on mult and fsb and V).

Good luck

the Motherboard may not be compatible with the new CPU. i had a problem upgrading my 650 to a 900Mhz a while back, and i got the same thing. it just went into standby. once i put the old one back in, it worked just fine. and i found out that my motherboard only accepts up to 800Mhz.

i will make the same assumption, so check the CPU for any special things as well as the motherboard. you may only be able to go up to a 1.1, or 1.0.

Kt7's can take a 1.2ghz proc, they can actually reach 1.4ghz but you have to remap the 6X-14X. Have you got the latest BIOS? Should do like daveleau said and try that duron back in, maybe you just knocked the RAM or something like that, if the duron work's straight away try a BIOS update then if it makes no difference take the cpu back and get another.

I've had a similar problem to this myself.

I replaced my Duron 750 with a 1 gig T-Bird (266 bus) and it didn't work. I replaced the 265W PSU, and Voila!

It turned out that the PSU I had was not Athlon compliant.

(Duron Compliancy is 14A along the 5v line, whereas Athlon Compliancy is 22A along the 5v line.)

Hope this helps,

Great idea chunky....can't belive I didn't think of that....must be getting older http://www.sysopt.com/forum/smile.gif
The T-birds need 1.75 but the durons only need 1.65. Need more power usually.

[gyoung]

Yeah, since I swapped the Tbird in and out with the Duron about 6 times and the Duron always works (I've also reset the CMOS with the jumper), I figured it is either the power supply or the Tbird is fried.

Not sure if I fried it or not.

I guess my next option is to have a buddy of mine put it in his KT7A and see if he can get it to work. If he can then my next step is to get a bigger power supply.

I'll keep you updated.

[gyoung]

I removed all of my PCI cards and unplugged all the fans (except the Heatsink fan) and all the CDROM drives and still a no go. It did the same thing.

I'll let my friend with a KT7A give it a try to see if he can get the CPU to work. That will probably answer my question. If it doesn't work then it is the CPU. If it does work then I don't know what to do.

I'll keep you updated...

[Roraycr]

Be sure the cpu fan is connected to the right 3-pin fan connection, the one furtherest from the CPU. I had mine on the left and ..nothing..moved it over and I was in bidness. Then I read the manual!!!!

[gyoung]

Check on that! I've tried it on both and neither one got it to work. I put it back on FAN1 (the one furthest from the CPU).

Some of the recommendations that I have been getting are to check my power supply. It is not on the AMD recommended list (Antec 300W PP-303X).

Anyone running this combo with an Athlon 1.2Ghz or faster? I did remove all the components (except for the Vid card) and it still didn't fire up. Could a power supply still cause it not to boot if nothing else is connected?

I was thinking of picking up an approved PS to see if it is the problem. If it isn't hopefully I can return it.

[gyoung]

I think I am on the verge of a breakthrough. Tell me what you guys think of this:
http://www.amd.com/products/cpg/athlon/techdocs/pdf/23792.pdf

Look at Chapter 7, page 27. It shows that a Athlon 1200 needs 38A to run. According to the power supply spec sheet, my power supply only provides a max of 30A:
http://www.antec-inc.com/product/powers/p303x_spe.html

If you look at the Athlon 900 in the techdocs, it shows that it only needs 29, which is just under what my PowerSupply is rated to (http://www1.amd.com/athlon/power)

Do you think that makes sense? Or am I totally off base here.

This is strange. I just had the same combo you have,a 1.2g tbird 200bus and a kt7 raid and i also have the same PSU the 303x and i never had any trouble with mine runnning, however, the guy i traded the board to has the exact same chip as you and i and he is having the same problem as you. Nothing but a black screen. I ran it at 1300 the whole time i had it. 24/7 runnig folding at home and never had a hiccup. Strange indeed. WEll i hope both of you get your stuff running. If i was gonna get a new psu i would get the 430w enermax. very nice supply. heck i may pick up one myself

[Jeffy]

If so, you can try to use the jumpers to underclock the chip to 900 mhz to see if it boots. If it boots, then it is not a chipped cpu n it's the psu!

[gyoung]

I've tried that, but from what I've read the CPUs initially load up to what they are configured on chip, then the BIOS overrides it.

In this case it never can get to the point where the bios overrides it, thus no boot.

[AdamAdsy]

you sure about all these power things, ive got a tbird 1ghz and im only using a 250W power supply, ive also got a geforce2GTS and loads of fans + sound blaster live platinum (with the bay) and ive never had any problems with it. The case was really cheap so i dont think the power supply is more than 250W (Thats what it says on it)

My best bet is that since it didnt work on your friends, it is probably broken and needs replacing.

Real nice language you have there George Baker.
removed last sentence. MntSnow has taken care of it. Thank you MntSnow.

Don´t forget, about 10% of all the TB´s that go over the bench are *deleted* up, I got my self a KT7a-raid and a TB 1200 fsb266 and I had the same problem. I tried a couple of things but nothing worked, so I got my self a non-broken one and guess what, it worked, it recognised itself as a perfectly normal TB at 1200 (this was of cource before I got a hand in the softmenu III) so forget all of this *edited* and change em for another one, besides there´s little pokin´around with the jumpers anyhow. Good luck at the store...


*edited* Due to language. I strongly advise you to reread the Forum's FAQ's concerning language.

Thank you in advance for your anticipated compliance. -Mntsnow

As I said.. you need the correct current...

I found that the min power for Duron was 150w, wheras Athlon needed 200w min.

(though too much of a pull, when u consider a 22A draw)

[Roraycr]

I'm running a KT7A-RAID with a 1.2 T-Bird and an Antec PP-303x @ 1260(9x140/35) with no problems.

[gyoung]

Yeah, it's a dead processor. I took it to a buddy of mine and he got the same thing. No beeps, nothing.

I'll have to either try and get Ubid to take a return or go through AMD.
