OC 1ghz AVIA

[Guest]

ok, so heres the deal, I fried my last 1ghz Tbird(axia) and sent it back for a replacement. I just got it today, but I didnt get and AXIA, I got the AVIA. Now if I understand what I've been reading correctly, the AVIA must have the L1 linked in order to get the crazy OC power of the AXIA... I need a silver conducting pen to do this...Correct??

Question 2, when applying thermal compound (Arctic Silver) do I apply the compound to the entire surface of the CPU including the die?? Or to the whole CPU except the die??

Question 3, Using an MSI K7T266 mobo, when adjusting setting for FSB I am only given two options, 100 or 133, now right below that in the bios it has other FSB frequencies, but it also has another number right after it IE: 145/32.8
What is this second number? And if I use this FSB, and the clock multiplier should I adjust my vcore above 1.75???


Thanks in advance for any help.

1stly,

AVIA = not as good as AXIA. People pay premium for AXIA chips and your AVIA is unlikely to get as high as your old AXIA without extra voltage and cooling.

Q1. I think all AXIA chips (anyone not?) are shipped unlocked, so you will need to do the linking trick as you say on your AVIA.

Q2. Just apply ASII to the die. The die is the smallish rectangle in the center of your cpu 'package' Read the use instructions on the <A HREF="http://www.arcticsilver.com" target="_new">http://www.arcticsilver.com</A> webpage - they are very handy.

Q3. I'm guessing (don't use MSI boards) that 100/133 'FSB' setting is actually setting the speed of your RAM, not the chip/board FSB. The settings under that are the true system bus settings.

I'd expect settings like 145/35.9 which is the frequency of the clock bus and frequency of the PCI bus respectively.

The % of overclock on the internal bus = % overclock on the PCI bus.

Your internal bus will run (by default) either 100 or 133 FSB (200 or 266 double pupmed AMD) and your PCI bus will run 1/3 or 1/4 of this frequency - i.e. 1/3 or 100 = 33Mhz or 1/3 of 133 = 33Mhz.

Raising bus speeds 'overclocks' all components and some PCI cards are more okay that others with this. Also eventually your AGP and IDE controllers etc. all give up.

Hope this helps,

Pete

i bought a 1.33 about a month ago and it was locked, haven't tried unlocking it much but a mechanical pencil i had lying around wouldn't work -- maybe i'm just unl33t

Athlon-C 1.33@1.5
Asus A7M266 @ 150 MHz FSB
2x 256 MB CAS 2.5 Crucial PC2100 SDRAM @ CAS 2/2/2

you dont have to unlock it to overclock. just pump up the fsb to overclock it, you will get amazing results.

But for a 1.33 chip, using fsb only does not always give you great results...

My system would not run stable yet over 142FSB, so I run 11x142 for 1562Mhz. You need to up the multiplier for that else I'd lose 142Mhz... ;o)

but really in the grand scheme, youre losing very little performance wise. you will get much greater results overclocking the FSB 10mhz than continuing to overclock the mulitplier by 1x.

but if the FSB won't go any higher, and the multiplier will, why not put up the multiplier the extra 1x - that's my point... I couldn't get the FSB stable over 142, no matter what the multiplier...
