Strange old Rig 1st time cooling

[noob]

I have been given a very old rig
And I am wanting to OC it

It has ISA slots - 2

AMD K6-2 'chomper' 350MHz Socket 7
PC-Partner VIB878DS motherboard
Chipset VIA Apollo VT82C598MVP
Northbridge: VIA VT82C598MVP
Southbridge: VIA VT82C586
64MB RAM dont ask what type its old!!

I can have 2x64MB in the 72-pin SIMM socket
and 2x128MB in the 168-pin DIMM socket

Anybody even remember computers with them

Some stuff on the Mboard

I would like to know how far I could push this chip – could it only go another 50 to 100MHz or could I potentially double the speed

I am looking at TEC cooling with water
I looked up the chip and the max thermal dissipation is 19.9W

So was thinking 1 peltier about 70W direct onto the CPU and adding the max dissipation of the CPU + 1st peltier + a bit, place a second directly on top of the first that is about 170W.

Then water cool the lot – including small water cooled heatsinks on both the southbridge and northbridge.

I am planning to build the custom water cooling myself,
which is no problem

Any suggestions on further cooling areas

I am wanting to use it as a server / firewall to my main rig and maybe do some folding on it

K6-2's are set by jumpers i believe. So you can get whatever your board will give, provided you have sufficient cooling.

the later K6-2's would do 450-550 outa the box, but 550 is about all they would do if I remember right

I'm pretty sure that 350 should do AT LEAST 400, but I'd shoot for around 450. I had a 450 that did 550 but I think I had to use a TEC to get r done.

the voltage can be set from 1.8 to 3.5V by jumpers on the m'board, it the same for the bus speed, multiplier and the dividers
The TEC and waterblock should give about 250W of cooling hopefully get temps down to about -40c
Just wondering if worth it, if I can only get about 100MHz out of it I wont spend so much - but if I can double it
Just wasn't sure what they would do
Also couldn't find anything about the old K6 on any of the forums

K6-2 CPUs weren't very good overclockers. Fifty MHz was typical, 100 exceptional. The .18 micron K6-2/3+ mobile CPUs were better overclockers, but not by a whole lot. The full speed L2 cache was their biggest advantage. If you wanted to improve performance, one of them, or a standard K6-3 would be your best bet. But I don't really think that is the point here.

That board can run as fast as 600 MHz, maybe faster if there are settings for over 100 MHz FSB. The multiplier is in the CPU, 6x is the maximum. To get 6, set the motherboard for 2x. Your 350 probably has this, but I doubt it will do you much good. The chances of hitting 600 MHz with that chip are very slim, no matter how you cool it.

the VIA MVP is the overclocking K6 chipset to have. Keep in mind the fact that it can use 168-pin SDRAM, OR 72-pin EDO ram. Not both at the same time. It will boot, but it either doesnt address one bank, or does both extremely slowly. Whichever, it hampers performance considerably.

Thankx guys

Think I'll just go with one ~150W Peltier and water cooling.
I can get one for about $35NZ (~$20US)
I'm hoping there will be enough room for watercooling the northbridge and southbridge.

Will keep you posted
