My computer was supposed to be 1.30 Ghz, but I just found out after a year that it was underclocked to 1296 Mhz. Is it ok to clock it to the right speed?:D
Oh and how far can I overclock it with the standard cooling it came with? Anyone think 1.35 is possible? 1.4? IT's and HP Pavillion 9800 custom.
Also, I need a link to a beginners guide to overclocking
Thank you!
HP=bad for O/C and will not happen as its all OEM and OEM dose notb support O/C at all. Sorry you are SOL.:(
I am sorry to tell you that computers that are built by companies like HP, Dell, Compaq, Gateway, etc are NOT overclockable. The limit these options. What CPU do you have??? Intel? AMD?
DOH :(
Intel P4
WAAAAAAH!
1.3ghz P4?? You sure it's not a Celeron? ;)Quote:

yeah, the slowest p4 ever produced was a 1.4, so you kinda can't have a 1.3 p4....definately possible to have a 1.3 celeron though...Quote:

and, regarding the 4Mhz "underclock" it's not really an underclock, but just how the motherboard clock generator electronics work. they're not always exact. for example, a celeron 1.3 Ghz processor runs at a 100mhz fsb with a multiplier of 13 (13x100=1300). now, say that the fsb clock isn't EXACTLY 100mhz, but rather 99.7. if you take 99.7 and multiply it by 13, you get 1296.1, which is pretty darn close to a 1.3Ghz celeron.
for another example, my motherboard overclocks my processor by a little bit. my xp1800+ should be 133x11.5=1529.5 (or what amd says is 1.53), but it's actually about 133.64x11.5, which makes mine in actuality run at 1536.86, or about 7Mhz more than it's "supposed" to
Wrong. There is a 1.3Ghz P-4.Quote:

I DO have a 1.3 Ghz P4! :mad:
there was one but few knew of it since the p4 willy was so slow. a 1.3ghz celeron is fasterQuote:

Dell used the p4 1.3ghz processors in their budget systems before.Quote:

Yes we know, relax...Quote:

I feel your pain, my second computer is an HP and I can't overclock.:mad:Quote:

ALso remember that all these numbers are approximate.
1GHZ = 1,000,000,000 cycles per second. So, in reality, it is continually varying from anywhere between (say) 843,443,912 cycles in one second to over 1,233,411,990 cycles in the next second. So its just an average estimate that the clock will sustain 1x10^9 cycles each second.
So, 1,296,000,000 cycles that is showing on your screen is approximated at 1.3GHz for ease. A computer is never going to perform EXACTLY 1,300,000,000 cycles each and every second. Thats an impossibility.
So, we approximate.
