Did I just fry my Duron?

[chexi]

While trying to OC my Duron 700 on my MSI-Pro 2-a mobo, I kept failing to post at anything above 800. I checked this site, and found a hint to actually lower the voltage instead of raise it. This worked for me to 850. I just tried 900 though, and it kept resetting. Worse, now all I get is constant beeps with the keyboard initialization error. Won't post even after I moved the jumper (several times) to reset the CMOS. I can't imagine that this chip would fry at 900 right off the bat, but I'm at a loss of what to do now. I can't even get into the CMOS.

I've double checked the video card, it's secure. I'm using the GlobalWin FOP38 with arctic silver. I don't think this could be heat related. I think that the voltage won't reset to default for some reason.

Took battery out. Did not help.

try reconnecting the L1 bridges. i did mine wrong and thought either hte mobo had died of the chip was dead.

Did you get that beeping? I've tried everything else, so I'll redo the bridges.

I also checked the power supply, which was a 250 Enlight. I put in an Antec PP-303x 300. This did not help either.

What I get is the LED error code for keyboard initialization failure along with high rate of constant beeps almost immediately after turning on. The LED's don't cycle at all, the go straight to that error code.

I've tried taking out the power cord several times, resetting the jumper several times, and even popped the battery out once. This really blows.

I really think it's the Mobo that got fried. Could a short in L1 bridges fry the mobo? Anyone have this?

I don't think a short on the L1 bridge could fry the motherboard. From what I know the motherboard just sees the multiplier setting from those. It sounds maybe like one of your connections got messed up and it obviously doesn't recognize the chip. Redoing the bridges should correct the problem.
Or the other situation is that the mobo is defective, independent of this situation.

Mobo is defective. That is the answer.

Hey, I have the same set up. I can go 850 always. If I go to 900 I am ok the first boot. If I shut it off and try to reboot it gives me the keyboard error. HOW did you confirm a defective motherboard? I need the argument for a replacement. Thanks

AMDMike,

Do you by chance have this mobo in an Elight case? Specifically the 7237? If so, before you fry your mobo, take it out and count the number of support clips/posts that are on the mobo plate. If you've got 7, you've got too many. Take the one out that does not have a corresponding screw hole in the mobo plate (you'll see 2 pretty close to each other, take the one out that's closer to the edge). This clip is for a different type of mobo (e.g., my old Soyo for my K62 had 7 holes). This extra clip sits right under the keyboard controller and will short it out.

Can you reset your mobo so that it will still POST at a lower cpu multiplier? I can't even do that. It absolutely will not reset, at least no way I've tried. If you tried something unusual (other than the jumper) and it worked, please let me know.

As for how I determined that the mobo was defective, I took it in to a local shop. A very good shop that specializes in overclocking and sells this mobo. They tested it for me, along with the Duron and found that the cpu was good but the mobo was bad. So that's how I know. This was after switching the battery, resetting the cmos jumper, changing power supplies, etc.

Hey,
I don't have a Enlight case although that was one of the finalist. When I run it at 900 and shut it down an try to restart it within 30 min. it just beeps at me( I ASSume it's a Keyboard error by what the LEDs show). If I wait until an hour has passed, it will reboot at 900 without clearing the CMOS. I've never managed to get it to reset by itself. I never pushed this board past its limits.

Also, it resets at the 700 MHz level even though I've connected the bridges with a conductive pen.

This is the first MSI board I've owned and I can say that I would buy another.

Well, you may want to check your connecting posts on the plate just in case. The tech I talked to who looked at my board said that the one return he has ever had on this board was for a faulty keyboard controller. So you may have gotten a defective one.
