How far can I OC an Athlon 1.4

[cmcquistion]

I'm wondering how far I can safely overclock a 1.4 GHz Athlon.

So far, I've increased the FSB to 144 and the Multiplier to 11, for a grand total of 1584 MHz.

No problems so far. I run a watercooled setup on an FIC AD11 motherboard with 512MB PC133.

My temps, at 100% CPU use, are 102 F on the cpu, while 75 F system temp. This translates to about 39 C and 24 C. My 5V voltage is pretty stable at 4.94V, sometimes dipping to 4.91V.

I can keep increasing the multiplier, but I'm worried about pushing the cpu too far. Is there any indication, I should look out for other than CPU temp?

Any advice would be appreciated, I'm new to overclocking.

As long as your temps stay good go as far as you can until you get problems, prime 95-3dmark 2000-2001 are all good programs that will fail when you go too far.

Most people max out around 1.6-1.8ghz.

Long as temps are OK and you don't have an ungodly VCore, keep going. My 1.4GHz hits 1.66GHz air-cooled at 1.84V which is default on my 8K7A+. I get either no post or kernel error in Win2K when tryin over 1.7GHz.

Keep going, just don't OVERdo it.

Best thing is to run your FSB at the default 133MHz and see how far you can go with the multiplier alone. Once you find that then you can back off the multiplier and start raising the FSB to get to that speed.

Good luck and keep us informed!

MotherBoard Monitor 5 says that my core voltage is 1.91 volts. Since I didn't manually change the voltage on the motherboard, I'm assuming that it is automatically changing it for me, depending on the FSB and Multiplier. Is this correct? Is 1.91 Volts ok?

[Placid]

Yes 1.91v is ok.

I was able to get my 1.4 to 1.61, but when I ran some memory tests, I realized that the memory runs better at 1.584 than it does at 1.61.

1.61 = 140 * 11.5
1.584 = 144 * 11

I think that I will get better overall system performance with the higher FSB and lower multiplier, even though the processor speed isn't quite as high.

Does that seem right?

the fsb overclocks your entire system(pci,agp,memory) as well as the cpu......so this will give u overall better performance. The multiplier will just overclock your processor and nothing else.....You are more safe if u just use the multiplier but the performance is less. I like a higher fsb than multiplier

My bird runs at 11x146 @1.6 on air,volcano 7 heatsink.;)

your mulip. doesn't control your speed of the system the lower the muil. the better off you are if anything you want to up your fsb as far as you can go wihtout crashing fsb runs the entire system faster,which is what you want.Also the lower the muilt. the lower your cpu tem will be.

ive done 8 x 166 ( max on mobo )

mmmmmm factory unlocked :beer:

FSB makes a huge difference to the processor. I would go for a low muliplier and a high FSB everytime.

Why do you say that? It's a fact that increasing the FSB will get you a greater performance boost, and the general consensus here is that a high FSB is the way to go. I'm not attacking you, I just want to know why you think that.

I posted that? It must have been my co-worker, or I was
asleep. :rolleyes:

I Personally would recomend the a higher FSB,
because it would not only overclock the processor but the
PCI/AGP/MEMORY ect.
