Prime 95

Heh... where can I get Prime 95?

Oh, and what is the advantage of upping your IO voltage?

crank up i/o v only and only to keep the system stable at higher mhz. Try to keep it as low as possible because you don't want to fry other components...

[Hoot]

Tim's right. You increase the I/O voltage to allow you to stabilize your system in the presence of increased FSB settings and more agressive memory timing schemes.

And then if IO is for upped FSB and aggressive memory timings, then what is Vcore for?

[Hoot]

The biggest factor behind upping the vcore is to stabilize overall CPU speed (mult x fsb) for a given temperature.

Little problem though, can't even get the computer to turn on unless I up the Vcore to 1.75 or higher with 8x133, I'm thinking I will burn in the processor for a few days, THEN try and bring it back to 133fsb (Everything runs fine at 133 except for Prime95, which gives me errors at anything above 950).

Another question, what has people been having the most luck with? Seems like most people go about 1.05ghz with their 800, but @ what voltages, IO and Vcore?

Hello Hoot; Do you know how to run 2 or more Prime95 processes on a SMP machine? I want to try my little sweet SMP system to see how well those 2 CPUs hold up under full load of Prime 95 processes. Many thanks.

[Hoot]

You got me there.

supraway; here is what I got from my 800 Duron @1066mhz

code: AKCA0107??? week 7 of 2001
Vcore: final setting 1.85v, V I/O: final setting 3.6V
CPU temp: fluctuated: Idle: 20-29C, fulload under prime95: 31-39C
OCed: final setting is 8x133=1066 :-) :-) :-) I love to stay at 7x145=1015mhz
but the Quantum Hard drive is so picky, while my other goody maxtors had
no problem with 37mhz PCI bus during the last 3 years on my 366mhz celeron 1,
Oced up to 5.5x110mhz=605mhz. I just got the second Celeron to make a sweet
dual Celeron at 605mhz, SOOOO CHEAP UPGRADE AND SOOOO COOL :-) :-) :-)
For me the higher the FSB, the better but Nothing I can do to get higher FSB
on my 8x133=1066mhz, using Quantum Hard drive :-) :-) :-)

The early 600 Duron and 1G Axia Tbird are the kings of Ocing in terms of
price/performance/Ocing. For the 1G+ expectation, the 800 Duron and
the 850 Tbirds are the safer bets. Because in my own experience, almost
always, every single Duron can get the extra 250-300mhz and every single
Tbirds should get the extra 150-200mhz with ease, provided they have
good components. :-) :-) :-)
