Firing up old tech

[Junk Parts]

RatDude gave me a Gigabyte GA-5AX Mobo with 768 megs pc100 ram, and AMD CPU. His CPU is as follows: AMD K6-2, 533 AFX, 2.2V CORE/3.3V I/O Socket7. I am putting my old AMD CUP in it. My specs are as follows: AMD K6/2, 450. All the rest of my specs seem to be a match except for the fsb speed. I changed the fsb to 4.5X for my chip. This should be about right. I don't think that I need to change any of the other settings on the board. Going to plug it up now and see if smoke comes out.

Re: Firing up old tech

slightly confused i am.
is the mobo so old that you're setting fsb speed with jumpers?

Re: Firing up old tech

Do you mean you are setting it to 100mhz fsb with 4.5X multiplier?

Most of these old SS7 boards had to have the FSB and multiplier set manually.

Re: Firing up old tech

btw. why put slower cpu (450 vs. 533)?
is cpu on that mobo fried?

Re: Firing up old tech

As 370forlife pointed out you need to change the FSB too. It will probably work if you don't but the CPU will run slower than 450. It will likely run at 437 MHz if the board was set correctly for a 533.

Re: Firing up old tech

iirc, he liked his old cpu better because of "memories".

what the hell, who honestly gives a S*** about that!

honstly i'd oc the 533 to 550... why not?

btw, the 533 setiing was a goofy one i calculated, the fsb was NOT at 100mhz! i used to run it at 500mhz a long time ago... back when i was pushing powmax cases...

still, glad to see he is using it.

>iirc, he liked his old cpu better because of "memories".

ah yeah, nostalgia...hehe....
but in the end he'll just have slower machine...but not much slower...heh

i'm sure he'll keep faster one as a spare...

Re: Firing up old tech

Hey, memories are worth something. The P4 2.53 in the computer that is now downstairs pretty much raised me. Was the processor in my rig from late 5th grade all the way through the end of my sophomore year of high school (at which point I went without a computer for a few months, and then my new C2D took over).

Re: Firing up old tech

450mhz has about 6x more memories than your 2.5ghz!

Re: Firing up old tech

I'd see if you can go 4x133 with that processor. I once had a K6-2 350 that would go 450.

Re: Firing up old tech

yes some of those can be pushed real good.
just dont go overboard with bumping vcore.

Re: Firing up old tech

Wouldn't the later ones be the same CPU just under clocked. I had a 450 as well. I don't think I set it any higher, it was a socket 7 upgrade for my first Pentium 133.

Re: Firing up old tech

Yes its "Memories"....and I didn't anything better to do at that moment. V core, and V I/O are at spec for my AMD K6/2 450mhz. Yes the board has jumpers and dip switches too. The jumpers set the fsb speed ie for my cpu its 100mhz. The dip switch sets the x multiplyer for the CPUmhz ie fsb multipied by x multiplyer setting should equal the mhz speed of the CPU.
I played around with it awhile today, and my 450 is now running at 501 mhz. Its still to slow, and the old AMD lacks some instruction sets so its kind of worthless but its fun. By the way my "fast pc" is a 2.4 P4, 533 fsb, 1 gig DDR ram. Its got a neat power button that lights up when you push it too!
