system specs:

1.33 tbird axia @ 1.33
asus a7m266
256mb pc2100
geforce 2 ultra 64ddr
temps seem locked at 52C

I'm confused about the Core 0 and Core 1 voltage reports in MBM. I assume Core 0 is the vcore and it's at 1.87. The Core 1, which I have no clue about, is at 2.54. Regardless of how I set the jumpers the voltage on the vcore never changes more than .1 and the Core 1 voltage doesn't change at all. My temps are astronomical right now I'm at 52C and when I try to OC i get up around 57C but at 1.43ghz I can't finish 3Dmark. I don't know how to get the voltages where I need them on this board, any help would be appreciated. Someone posted a link about a dip switch mod I can do to affect multipliers but I don't know what these 'multipliers' affect. I'm also confused about the +3.3, +5, +12, -12 and -5 readings. What are they telling me? My biggest concern is getting the vcore voltage high enough to power this tbird overclocked and providing enough to the io to keep it stable. So far no good. I'm still not sure what I'm doing wrong. I've tried jumpered mode and am back to jumper free with little change in anything other than the fact that now my temps are higher. Totally lost STILL. I know I can push this chip faster but not with pissant power. If I join the L1 bridges to unlock the multipliers and OC that way will I still need the increased voltage? Are there bridges on the chip that can be joined to allow increased voltage? Hell, I don't even know if voltage is my problem.

c'mon please I could really use some help on this. i know i need more power but i just don't know what's what in mbm and the extra power is hard to find.

Sounds like you doing some ocing for the first time. Study the manual that came with your mobo there is a lot on information in that book. Also there is a wealth of overclocking articles on this site, do a little digging and read as much as you can you may be supprised how much you will learn.

A lot of problems will just dissapear after you do some reading and you will wonder how did I ever make that mistake?

i don't have any experience with the a7m266, but i can offer a few pointers in the right direction.

on my mobo, core 0 is the one you want. i.e. the actual core voltage. the other one is just a leftover from code for dual processors i'd imagine. don't pay any attention to it either way.

you'll have to ask someone else about changing the voltage to you proc, or read your manual. that's motherboard specific and i don't know the a7m266. you will be able to do it somehow though.

about your temps: what cooler are you using? chips like your's chuck out a lot of heat becuase of the speeds they run at and the voltage they use. you need a good cooler for that processor. alpha, globalwin and swiftech all have excellent offerings for high-end socket a processors. your temps are definitely too high for any sort of overclocking, and will have to come down to get you stable.

the multipliers the mod refers to are to change the cpu multiplier from its default value. the cou's speed is governed by the following formula: speed = frontside-bus speed * multiplier. manipulating the multplier can help you overclock. i.e. you lower the multiplier and up the fsb. i'm assuming the a7m266 doesn't support this naturally, which is why it needs the mod. again, not sure on that.

the voltages you're confused about are as follows:
3.3v.. io voltage for your board. cards, mobo, ram run on it akaik. maybe other devices too...
5v: hdds, cdroms, other devices use this.. as well as 12v usually.
12v.. most fans, other devices connected to by molex connectors.
don't worry about the negative readings...

i think you should get that cpu cooler, and learn a bit more about overclocking before you attempt it. you've got a great system, and it would be a shame to kill anything. i suggest you read as much as you can in these forums, in the relevant sections. i.e. cooling, memory, amd motherboards, amd cpus... post if you have more questions, but the best wau to learn initially is to read, read and read some more.

good luck, and let us know how it goes! :)

Thanks for the help and great advice. I'be brought everything back to default and am running at about 49C load and hopefully still 32C idle. That's still way too hot, like you said. This is my first time but I'm definitely following the cautious steps and have learned SOME. My heatsink is a swiftech mc370 with a 4500rpm (thinking of going up to delta) ys-tech 26cfm fan on top. I have a coolerguys wind tunnell 2 with some 5 or 6 fans attached to keep temps down but, yeah, it's still hotter than hell. My confusion is mainly coming from what seem to be motherboard specific problems, ie "what does this jumper do?" It's come to me from others that one of my manipulatable voltages VIO1 is not normally changeable on most boards. Many questions but yeah I guess I'll just keep reading. Some people say give it more power, some say give it less. It seems, though, that the jumpers which claim to change voltages actually don't.

PS- I've STUDIED the mobo manual but to no avail. Some of the information doesn't even coincide with the retail version they shipped (ie. the mod). Not to mention, it's rather esoteric and I've obviously still got a lot to learn. Hey at least I can oc my video card! woohoo

Asus makes the latest versions of there manuals available in PDF format. Download the latest from there web site it just might contain the information that you seem to be missing.
