View Full Version : High FSB overclocking

Here's a question for all of you Intel extreme-FSB overclocking mavens.

My brother sent me a link to a post on Madonion.com. It was a CPUID screenshot of a PIII cB0 500 running at 975MHz, thus running a 195FSB. This was on an Asus CUSL-2C, so I find the memory option -33MHz to be plausible - he claimed to be using PC150, so no problem there.

One question is, how easy is it to trick CPUID? I'm not saying he did, but I've almost never ended up with perfectly round numbers for the FSB speed, CPU speed (My 1GHz Athlon always shows 1008 MHz on my Asus board), with fractions thrown up all over the place (100.83 MHz FSB, etc.). Does anyone else ever really get perfectly round CPUID numbers like this guy apparently did?

Another, is how dangerously unstable would any system with the FSB clocked this high be? He said he had GF2 and SBLive, and it would clock 210 FSB with no SBLive. Wouldn't the USB devices, etc. die long before that? And what about the hard drive controller? What are the implications of a doubled FSB speed?

(Yes, one of those is my bro flaming him ;) ) He thought for sure this one was faked - I'm not so sure, since I've seen some mad overclocks in this place, most of which I trust, since most people seem to be pretty honest in this forum. I'm leary of other (Madonion, [H],etc.) because many posters seem anxious to get bragging rights, etc.

Tell me what you think, K?

Its easy to fake cpuid.
The fsb is possible but that cpu making that is highly doubtfull with air cooling if it were a amd cpu with the multiplier unlocked that wound be different.
I checked the cpu database here and 667 is the highest overclock listed for any p3 500 cpu. If he is getting 975 then he must have a very special cpu.

Its hard to say if its a fake or not 195 is possible, i'm running at 171FSB and theres a guy with a p3 1g that s in the CPU database who says hes at 195 with great cooling, since ive been here ive seen no one higher then 171 with my CPU but there out there. Every once in a while a really good chip is put out there for the picking [just like the overclocking lottery that it is. :) ]
