1.4 AYHJA can't overclock much

[JungleMan1]

hmm i seem to be having some problems here...

well i have a 1.4ghz Athlon ayhja which is supposed to be very overclockable, the Epox 8k7a which is also supposed to be very overclockable, Arctic Silver 2, Thermalright sk6, and a Delta 30cfm fan. i can do 11.5 x 133 and take it up to 1533, and it runs fine, I can take it up to 1600 but I did have some problems, after that I can't go any further.

VCore is 1.96, I forgot what the IO voltage is but it's above normal. even the 5v rail is 5.08 or so (Antec PSU tweak).

I thought these were supposed to be overclockable, I cant eke out more than 133mhz! Please help, thank you

you could try redoing the L1 bridges I guess....you didn't say what you closed them with...jack the crap outta the voltage and give it another go. what kind of ram are you using?

[JungleMan1]

L1 bridges? I didn't do anything to those, i have no idea what they are.

have a look at <a href="http://www.motherboards.org" target="_blank">www.motherboards.org</a> for the article titled "Unlocking the Duron and Athlon using the pencil trick" explains it all with pics

i am really not in the mood to remove my heatsink, fan, and shim and go in there to do something.

what does it do? how could it be necessary to overclock if I have already gone to 1533?

You don't need to mess with your L1 bridges because all the high end AMD chips are coming unlocked from the factory. Basically the L1 bridges determine whether your multiplier is locked or unlocked. What kind of problems are you having? And at what speed do they occur. Have you tried using a higher multiplier, or a lower multiplier and a higher FSB? Try messing with some of that or post some more info.

Congratualtions on gettting it to 1533. I suspect that is as far as it will go. Remember each cpu is different and some will get higher than others. For a better performance increase try reducing your multiplier and upping to 136 or 137 fsb. That will give you greater increase than just upping the cpu speed.

I agree, get your FSB up. I have my 1.2 set at 1.4, 140FSB x10 and that's on the Abit KT7E, not known for overclocking.
with good RAM, PC150 or more, you should be able to your your FSB to at least 140-145, with a multi of 10 or 10.5 that will show increased performance across the board.

What's your temps at too? Anything below 50C under full load you should be good to go.

Runs stable at 143 x 11, before it was at 11.5 x 133. It was stable at 11.5 x 133 also, but 143 x 11 is more than 11.5 x 133.

The CPU runs at about 54 C..thermalright sk6...delta 30cfm...2 case fans..what am I doing wrong? is it the shim? <img src="confused.gif" border="0">

Haha Jungle you aren't doing anything wrong. Like someone said earlier, be glad you are getting something out of the chip. AYHJA is a known good stepping, but each chip is different. There is no guarrentee that you will get a 200-300MHZ additional out of a chip designed to run at 1.4. BUT I know the quest to achieve higher is addicting Try taking off the shim to see if it helps you get any higher. Better yet take all your cards out but your video card and see if you can go any higher, or disable your floppy controller (FDC) in bios, or disconnect one of your HDD's if you have more and see if any of that is limiting you. Disconnect your cdroms as well. Then go step by step plugging them back in till you hit a wall.

No, not doing anything wrong as in why won't it top 1600.

what am i doing wrong as in why is it running so hot??? could the shim removal cool it down?
