here goes my last o'clocking question...last one

[Guest]

I'm out of thoughts and ideas why can't I o'clock my 800Mhz tbird 200fsb, no hope at all, I won't ask anything about my problem anymore if no one can answer that.
ASUS A7V KT133, FOP38 for CPU cooling.
800Mhz Athlon TBIRD 200FSB (L1 bridges are locked succesfuly
448Mb of CAS2.5 pc133 RAM (3 modules, 2 of them are 64Mb and 128Mb of good CAS2.5 Kingmax pc133 RAM, the other module is 256Mb of cheap CAS2.5 pc133 Generic RAM)
GeForce2 MX 32Mb
Sound Blaster Live! Value
U.S.Robotics 56K modem
A little thingy that connects to the mobo and has about 5 additinal USB slots
Lexmark Z52 printer (via USB port)
Samsung SyncMaster 955df monitor.
300w case with 2 fans blowing.
I have this cheap module of pc133 RAM and I set it to pc100 for succesful o'clocking. I set voltage of CPU to MAX my board allows, RAM set to 3.5 voltage. I can't set my FSB higher than 105Mhz via DIp switches and can't o'clock FSb via BIOS at all. Higher than 105Mhz - computer won't post. I tried setting multiplier from 8 to 9 and won't post. Temperature of CPU is always 43 celcius, even when o'clock.
What is wrong that I'm doing? Thank you for any advice and if you don't have to say anything then don't say anything at all, please.

here is your problem
"800Mhz Athlon TBIRD 200FSB (L1 bridges are locked succesfuly)"
you want to unlock them, by connecting the bridges, then you can overclock through the multiplier.
and that motherboard doesn't overclock through the front side bus at all in my experience. some people claim 110 and no higher but I personally got to 105-107. You also might need to up the voltage a tad.

The problem you are having is related to your mobo, not your ram. The A7V has little luck with increasing FSB over 100. The highest I've seen anyone get is 110. So overclocking via the FSB on that mobo isn't gonna happen really. Just unlock the L1 bridges by connecting them and up the multiplier instead of trying to raise your FSB.

That oughta void your warrenty!

My guess is you have an early KT133 chipset and the FSB just won't go very high. Even the best KT133s overclock to about 115mhz. I feel for you. I have an Abit KT7 and my FSB will only go to 106mhz.

You also have a Tbird 800 which is not known to overclock very far. According to the CPU Database at <A HREF="http://www.overclockers.com" target="_new">http://www.overclockers.com</A> the average overclock for a Tbird 800 is only 970. Even that does not say everything. There were several Tbird 800s that just wouldn't overclock at all, not one bit.

You probably have to try another processor. Duron's are very overclockable but it will take one overclocked to 1000 mhz to outperform your Tbird 800 so in that case you might as well keep the Tbird. I hear the newer AXIA core Tbirds are very overclockable. There is a 1.0 ghz, 200 mhz FSB, version of this core. You might consider one of those.

It seems you have done just about everything you could possibly do. The only thing remaining would be one of the voltage modifications for your motherboard which would allow you to raise the maximum core voltage.

I ment UNLOCKED, I just wrote locked becasue when you unlock you join the bridges and it seems like you lock them, I did with a conductive pen, it worked. I know that before I could clock FSB to 112 and it would be stable but now...

you see, currently I'm not at home and won't be until September or so, what I'm gonna do is what tech. support told me from asus, they said they new BETA 1008 BIOS update and by September it won't be BETA anymore and they said they could o'clock one A7V up to 143Mhz and this is fenomena, but most of them will go as high as 118Mhz they said, but I don't know if I should trust them, I wonder wht 200fsb 1.4Ghz Athlon costs (with a new 1008 update i can put 1.4ghz tbird on A7V) more than 266fsb 1.4Ghz tbird??

143mhz! I'm not saying its not true but it is hard to believe. I think I have heard of one person claiming to reach 120mhz with a KT133 chipset. The later examples were definitely better than the early ones so I suppose it is possible that a few chips have exceptional capabilities. I just haven't heard of anyone reaching those kinds of speed.

If you want to do serious overclocking you'd be better off with a newer motherboard but good luck on whatever you do.
