PIII 600@?

[kristoffer]

Hey guys,

I have a Gigabyte Intel 440 BX2000 motherboard ( http://www1.giga-byte.com/products/bx2000.htm )

With a PIII 600 slot 1.

I wonder how, and how much i can overclock it?

I am pretty newbie, so please explain.

I know you guys can help me with this :)

Well, we are wondering how high you can overclock it too. Trouble is, nobody knows for sure. Depends on the cooling, CPU, motherboard, RAM, PCI cards, etc, etc. Typically, those P-III 600 chips have a good reputation for overclocking very well. I don't know what FSB settings your motherboard has, but I'd be surprised if you couldn't reach at least 800 MHz fairly easily. Anyway, the first step is to improve cooling, then increase the bus speed from 100 MHz to say 112 MHz at first to see how well that works and if it's stable. Good luck.

that depends alot on which p3 600 it is, ignoring all the differant steppings (which also play a part in overclocking) there are 4 differant p3 600's

The first is the Katmai 600, this is a 2v 0.25 micron chip with 512K external L2 cache.
Then there is the 600B, this is the same as above but on a 133mhz FSB
These 2 will not overclock much at all, maybe 50mhz at most unless you fancy pelt/water cooling them which isn't worth it.

Then there are the Coppermine 600's
The first of these is the 600E, 1.65-1.7v 0.18 micron on die 256k L2 cache, depending on the stepping of this it may overclock to 800mhz with a 133mhz FSB, Mr.B has one of these at over 900mhz which is very rare indeed.
Then there is the 600EB, same as above but with a 133mhz FSB and this also won't overclock much, maybe 700mhz or so if the motherboard and components can handle it.

It is likely that on a BX board with a Slot 1 cpu that you have the katmai 100mhz FSB chip, in which case you may be able to get to around 650mhz, if you are lucky and have a 600E then 800mhz is quite possible. You can find out which you have by using wcpuid which tweakfiles (http://www.tweakfiles.com) have under the cpu section, look at the L2 cache section, if it is 256k full speed then you have a coppermine, if it is 512k half speed then you have a katmai, and also look at the system bus speed, 100mhz is either a 600 or 600E and 133mhz is either a 600B or 600EB.

Even if you get luck with it being a 600E, you then have to take into account the stepping, I don't think there was ever a cCO 600 (I'm not sure, if there was then 800mhz should be a peice of cake) if it's a cBO then 800mhz should be quite easy, if it's a cA2 then you may need better cooling and extra voltage for 800mhz.

Thank you professor Phil, I had totally forgotten about the early Katmai core version of the P-III 600.

It does not make any sense too me. but to you?

whitch PIII600 do i have?

[Phil]

Yes it does :)
You have the katmai p3 600 on a 100mhz bus
You also have a tnt2 which bodes well for bus overclocking as I got my tnt2 ultra to run on a 133mhz agp bus (1/1 divider) before I fried it (not due to the bus speed).
I would expect you to be able to get to around 650mhz but not likely much over that, especially with out extra voltage which may not help as 600 is near the max of the katmai core, I recomend slowly moving up bus speed until it becomes unstable, you will probabally get to about a 108-110mhz fsb

[kristoffer]

so i can overclock my grapic card?

I wonder if it is possible to explain how i do this. Grapic card and CPU.. do i need new cooler?

Is it possible to give me a little lesson in what i have to do?

UPDATE: I just checked the spec of your board over at gigabytes website
unfortunately the next available fsb is 112mhz, you may get luck but I would be surprised to see it get that high but it can't hurt to try, make suer you know how to reset the bios settings before you try incase it doesn't post

What I was saying about the graphics cards is that nvida cards are very tolernt of high bus speeds. you can also overclock the memory and core of the graphics card as well either using something like powerstrip or tntclock or using nvidia's detonator drivers.
For overclocking your cpu you will need to increase the bus speed, this will be done either in the bios or with jumpers on the moherboard, you will need to read your manual or download it from gigabytes website and find out how to change your fsb and also how to reset the bios/cmos to default, then set the fsb to 112mhz, if it posts and works then you are away, if it is unstable then extra voltage can fix that, if the board allows you to change the voltage it is very simple otherwise you need to cover certain pins on the cpu which is not so simple, if it won't even post then you need to reset the bios and either settle for 600mhz or try with a high voltage.

OH MY GOD!

I did'nt think that was possible with any video card!

[Phil]

It was a decent little card till I mangled it, 133mhz agp bus, 220mhz memory, 185mhz core, of course this was with an unlocked p2 233 so it didn't exactly fly :)

[Mr B]

Mine is the Coppermine "E" version.

You know Phil, I didn't really think of my o/c as being rare, but, looking thru the database here on the front page, I only see two entries faster than mine, air cooled. All the others are water.....

Brief specs...600E @ 954, 1.95v. Alpha P3125 hsf, w/ two YS Tech 27cfm fans, Asus P3C2000 mb, 256MB PC133, Herc 3D Prophet II MX 32 MB (running 195/205), 30GB Maxtor 7200rpm, ATA100 (running ATA66).

Here's a screenshot of a couple of programs....after you mentioned it's rare, I thought I'd better take a "ss" for posterity....=)

This rig ROCKS !!

Thanks guys you've been very helpfull!

Especially you Phil. Thanks! :)

I am going to try to overclock on friday
