K7T Pro2-A OC problems

[Vampire]

Hoping someone can help me here.

I just put together a K7T Pro 2-A/Duron 600 system. Initially I tried connecting the L1 bridges with a pencil, but wasn't happy with the results. Then I went and bought one of the Loktite kits. Although I wasn't super neat, looking at it under a magnifying glass, it appears I connected the bridges properly.

My problem comes when I try to OC it. I've gotten it up as high as 800, with the chip voltage set at 1.65 or 1.70 (I forget which). I haven't messed with the FSB speed, just the multiplier. Everything seemed to run smoothly. But, if I power it down, it often won't boot back up. I get a series of beeps, then constant beeping, and the D LED (or whatever they're called) lights indicate a memory problem. The power and reset buttons become inoperative, and the only way to restart it is to unplug the PS. Sometimes when I reconnect the power plug to the PS, it will boot fine, other times I have to clear the CMOS, restoring all defaults, before it will reboot.

Anyone have any suggestions for what I did wrong? If it's the LI job, will alcohol remove it so I can try again?

Thanks.

UPDATE: I give up. I just restarted the computer, went into bios, set FSB at 103, multplier at 7.5 and voltage at 1.65 or so. It works at 773 MHz. Go figure. Wonder what it will do the first time I restart it?

UPDATE 2: Still seems to be running well, been through several power cycles.

I've experienced something like that... like when i had my multiplier set at 9x it would be solid but when i tried to reboot or if i shut down and then tried to boot up the motherboard would say something like the memory is screwy or it would just tell me to check the system and it wouldnt boot up. I had to pull the plug to shut it down and clear the bios. well now i'm running at 8.5x and i have the voltage turned all the way up to 1.7(my range is only up to 1.7 if i dont have the overclocker's bios) and it's stable and i can reboot and such. Well i'm guessing the problem is the voltage. Try to raise the voltage more and then try to reboot later in the day. you should also check the week of your duron.

Personally, I think the best thing to do whenever you get a Duron is connect the L1 bridges (if they aren't already connected) and the L7 bridges. After you connect the L7 bridges, you can select voltage settings as high as 1.85v.

Basically, Vampire, the whole memory deal must be a bug or something when you haven't overclocked successfully. I had the same problem on several occasions with my K7T Pro and I've just dealt with it. Thing is, when it does it, I turn the computer off, then on until I hear the monitor start beeping (indicating the memory problem), then off again, and then on (and I repeat the process two or three times) and everything's usually okay and the Duron's set at it's default speed.

Sorry for the delay, but thanks for the responses. I closed the L7 bridges also, running at 884 (8.5*104) now at 1.84 volts, temp doesn't appear to be a problem. can't get 9x to run reliably, guess I hit my limit.

Wow, I had the exact same problem this weekend, same mobo except a duron 650. Everything down to the beeps and the LEDs indicating a memory problem. I had to jumper my bios(which an anandtecher told me to do) back to it's default value before I could get it to post again. When it happened to me, it also screwed up my harddrive and I totally had to reformat it. I've been afraid to overclock since, just cause I don't want to have to start over and reformat it all again. Especially since I don't know what caused it in the first place or what I could do to cause it again. My L1 bridges were factory closed(or open whichever is needed to overclock) so I didn't have to close them. Maybe I should go back and try to close the L7 bridges now too. I only have the retail heatsink/fan though so I'm worried about temp. Anyone know if there is a heatsink/fan regarded as "the best" right now by a majority of the people. I know you cannot call anything the best but in my opinion many people believe the K7T Pro2a to be the best mobo right now, so I was wondering if there was a good HSF that could complement it.

i have exactly the same problem as you guys

why is that happened??

i got to unplug and restart again

WTH with the problem??
