1Ghz TB overclock... plz help, Im newbie

[Guest]

Ok, so I got this MSI K7T266 Pro with 256DDR(PC2100) and 1Ghz TB (266). The default is 133x7.5. The Ram runs at 266.
I tried to overclock, but I faced a lot of problems.
The multiplier only allows 8.5, above this no boot.
The FSB allows up to 164, but not stable. And if I overclock this FSB, the memory only allows 200mhz, or freezes above.
So 164x8.5 came out 1400mhz (at boot it shows 1200??) but after 10 mins use of win2k freezes, and after reboot crash when win is starting.

Any idea?
Thanks very much
Daniel Vinko

I forgot these:
I have a GW FOP32-1, the CPU is 41-45C.
I have a DTK 200W power supply. I read it needs 300W, but I think this DTK ps is better than many other 300W. At 1Ghz I have no problems at all with this ps.
I bought a noname 300W as well, but I dont really want to put it into my case. Unfortunatelly, no brand power supplies is available around...

"I have a DTK 200W power supply. I read it needs 300W, but I think this DTK ps is better than many other 300W"

Your crazy you better get a 300w power supply in that system.

yeah, get a 300W PS. and your 1 GHz TB can do upto 1400 MHz, maybe with some effort. what stepping do you have? i mean the numbers printed below the processor name on the die...

Jesh, 300w minimum, I recommend at least a 350w, I have a 400w P/S and I can take my 1.2ghz to 1.52ghz, 1.46ghz rock solid stable.

Somebody tell me plz why the hell does that Athlon need so much power???? Im stupid to the electrics, but I think that 1.8V comes out from 200W just as well as from 350W or 400W.
That 350W power supply would beat an industrial forge. It gives incredible heat.

My Athlon reads: AXIA. I dont remember the others...
Why is that the memory runs at 266 when the fsb is 133. But if I increase the FSB the memory only allows 200mhz. Or does not boot. Why is that??
Could it help if I increase the core of the cpu?
How much does it need?

When you overclock and raise the voltage up you are significantly raising the power the cpu is taking. A 1.4ghz T-Bird at 1.75v takes around 74 watts. When you raise that voltage up even at the same speed the wattage will go up to 100w plus. My 400w LeadMan PowMax LP6100D power supply is rated 30a (pretty high) for the 5v supply which supplies the cpu and other components in the pc. Right now I am operating my 1.2ghz at 1.46ghz with 1.91v to the cpu. I am sure I am approaching if not exceeding 100w of power to the cpu. So what does this mean:

100w/5v = 20a (20 amps is being fed to my cpu)
This means my 400w power supply has a surplus of 10a on the 5v line which is being used for other things as well. So everything is working well

Now lets take a LeadMan PowMax LP6100C power supply that is rated at 300w, its 5v line is rated for 20a:

100w/5v = 20a (once again 20a is being fed to my cpu)
Cpu alone is taking all that the power supply is rated for on the 5v line so in this case my power supply 5v line is being exceeded in which I doubt I would be able to operate my system at 1.46 and even 1.4 maybe to high of overclock with a 300w power supply.

Note the LeadMan PowMax 6100B, a 250w power supply is rated only 15a for the 5v line. What do you think would happen if I tried this setup - - It wouldn't work, at best it might run my cpu at rated cpu speed and voltage.

So if you are serious about overclocking then a 350w P/S is really starting to push it. A 400w P/S plus is probably your best bet.

Does this answer your question?

Ok thanks, I understand know.
So this hardware monitor shows 1,76-1,78V. Is it enough for 1ghz? What is recommended for eg. 1200mhz? Or 1400?

And Iam still waiting for sy who solves this ram problem.
Thanks again...

My 1.2ghz cpu goes up to 1.4ghz just fine at 1.78v on the cpu, at 1.46ghz the voltage needed is more, right now I am running higher then what is needed because I was experimenting with the FSB going over 1.5ghz. I will probably go back to 1.4ghz at 1.78-1.85v not because my system is unstable but because I just don't need it yet.
