Upgrade Pentium 233 mmx to AMD K6-2-500

[yawng]

Hi,
I currently owned a Pentium PC MMX200 using the 1998 Eagle mainbd socket 7 (No AGP Slot) .(model code 35833102)

I would like to:

1) upgrade the CPU to AMD K6-2 450 / 500 Mhz.
using current Mb.

Is this Bd compatible to K6-2-500 ?

What should jumper J6 be set to ?
(currently per the manual is empty, but need to change if K6-233 above is used)

Would the buss speed 66 Mhz be able to cope with this CPU ?

Would the system run faster ?

Or the CPU will be slow down by the MB?

2) Should I upgrade the VGA card to ??
But there are no AGP slot at all.

3) Since the System is purchase in 1998,
does the Bios support higher Hard disk say from 13 G to 20 G ?

could you someone please send me the updated Bios ?


Thanks

1) The best solution would probably be to buy both a new CPU and a new MOBO - The K6-2 needs 100 MHz FSB for maximum performance

2) Well - if your VGA card suits your needs, then why upgrade?

3) I honestly don't know - but i bet someone else does!

The AMD K-2 runs on a SUPER Socket 7. The MMX is a Socket 7. I did a similar upgrade, I had to get a new board. RAM is cheap.

You might as well just upgrade to about 700 or 800 MHz. It'll only cost about $75 more than going for a 550 MHz.

The K6-2 500 requires a 100MHz bus and 2.2V Vcore support. It also requires the 5.0x multiplier support. Official BIOS support also helps, but you might be able to get away without it by using utilities like SetK6 to enable some of the features of the K6-2.

I haven't heard of your board, but I can tell you what I did with mine. I have a contemporary of your board, the MSI-5148, a i430VX board. Originally it was running a P166MMX, but I wanted to upgrade it with something a little faster and give it to my parents. Lucky for me, it supports voltages down to 2.0V, has DIP switches for the 4.0x - 5.5x multipliers, and has an undocumented 75MHz bus speed setting. I put a K6-2 380 in it and set it to 375MHz (5.0*75) but it had stability problems. My guess was that something didn't like the 75MHz bus, so I set it to 366MHz (5.5*66) and the stability problems went away. I guess I could try overclocking at 400MHz (6.0X66) but for what my mom uses it for, she won't notice the speed difference.

I also threw out the 4 meg video card and put in a 16MB voodoo banshee PCI. It's not the fastest 3D card, but it does have very nice 2D and it looks real sharp on her 20" Trinitron monitor. Plus it was cheap. Nowadays you could try looking in ebay for a used PCI voodoo 3. I think buying a PCI voodoo 4 or 5 for a K6-2 system is overkill.

For the memory I put in 64MB using two 32MB DIMMs. Beware that older boards have problems with single DIMMS > 32MB. For instance, I tried putting a single 64MB DIMM but it only saw 16MB. Alternatively, I could have gotten to 64MB using 72pin SIMMS instead, but SIMMS > 16MB are ridiculouly expensive now. One thing to remember is that older boards based on the VX and TX chipsets only cache 64MB of ram. Adding more makes the computer slower!

I upgraded the 2GB HD and put in a 8.4GB drive. The 6x CDROM got replaced with a HP8250 CD-RW. The old SB16 got replaced with a generic Yamaha 724 PCI card.

This really isn't a bad system now. I can actually play some of the newer games, albeit at 640x480. Anything higher and it really slows down. Not a bad system for basic net surfing.

DanU,

A friend of mine has a PackardBell 200MMX that I want to upgrade for him to a K6-2 400 (66*6) but it seems to not have the split core and I/O voltages. Was this the case for you? If so how did you configure it? It seemed to me the only upgrade path was by using a Powerleap adapter so as to have the correct voltages and then still we would have to buy a new bios for it all to work right.
