40°C mit 1.65 Volt

I have recently bought an Xp 1700+ Throughbread A (DLT3) or whatever those letters were. Anyway its one of those Cpu:s that should have 1.5V Core voltage. I didnt need to unlock or anything, just choose any higher multiplier that was available and it worked without problems.

The problem, is that on my Abit KR7A board I cant get any higher multiplier than 12.5x. That brings it to 1667Mhz, but I want more! It seems I cant get much more than 140Mhz Fsb with this board due to the dividers (only 4:2:1 and 3:2:1). So this leaves me to get the multiplier up a notch. The Bios doesnt help me with that...

So, does anyone know if it is possible to use the Paint guide (Very nice) to set a higher multiplier and bypass the mobo? Would it work with this motherboard? Would be nice to know before starting smearing all kinds of things on the cpu =)

(I tried it at 1725Mhz, 12.5x138. Worked, didnt test much. But I only give it 1.65V and I can squeese it up to around 2V. So it feels like I could get more out of it.)

Adde offline OC Newbie 21 Jahre dabei ! AMD Athlon XP 1533 MHz @ 1667 MHz 40°C mit 1.65 Volt	Thanks for the quick answer. I tried to put the multiplier to 5x, it booted as 666Mhz =) Ill try to do it manually and see what happens. Do you have any suggestions which multiplier I should try with? 14x maybe? What does it mean when it says reserved on 14.5x in the guide?

I think 1667 MHz isn't bad at all for a 1700+ CPU, so i'm not sure how high your processor finally might go :noidea:

Of course you can try it with 14x, but no one can promise you that your CPU will work with this speed.
If it's possible you should set your FSB to 100 MHz before you try to increase the multiplier to see if you paint it successful to the right multi.
Otherwise it may be that your PC won't startup and you don't know if you made a failure or if your CPU doesn't like this higher frequency :ohwell:

The 14,5x multi doesn't work, even if this bridge settings should be the theoretical setting for this multiplier, so may be AMD will "allow" this multi in further CPUs.

Timex offline OC Newbie 21 Jahre dabei !	I've gone by what the paint job said and tried to set my FSB to x16.5 but it will not use that value. I'm using a KR7A-133R and it only list up to x12.5. By the way the CPU I'm overclocking is a TBred "B". Can anyone help me, I just need to know how it can be done. Thanks

To gain higher multipliers you must brake the L3 connectors.

Example, brake the last 2 L3 bridges to obtain a default 15x multiplier.

I am curious to know if this works becuase I want to do this to my cpu. If you have done it, please post.

Also, if you need to cut the bridges, follow this link for an easy method: http://www.amdforums.com/showthread.php?s=&threadid=191920
