k6-2 on a 503+

I have a 503+ (of recent vintage) which has been running on c CYrix at
about 250. I swaped it for a amdk6-2 but I cant get the system to run at
any speed higher than 95 x 3 1/2. Now let me say what I mean by not
running. For now it means not being able to boot w98. It starts gets
partway through the early stage(the wavy line on the bottom) and then
stalls.
It a scsi system with a DPT controller some 5 years old. Now my question
is what components are likly to be effected by an increase in the
multplier. The cache? the pci bus , the scsi controller. Suggestions
as to what might be the failing component and how to test would be much
appreciated--or does W98 need a reinstallation.

Thanks --but That's a win95 patch and I do know about that

I am not sure I undrstand what that means about the agp speed (which is
66). The memory is sdram pc-100 and the settings for memory as per the
manual (unless that's in error) But The failure occurs when I change the
multiplier.. I dont believe this has anything to do with memory (or does
it) Where is this AGP thig described- We are not using an agp card

I made that eror before but this time no . It's not that is slow but
the it stalls My intuition goes to the controller. Is this reasonable

1. what exact k62 cpu model are you using? some k62 CPUs were 95 MHz
fsb rated.
2. to check your memory subsystem out for proper operation get
memtest86 at www.memtest86.com ; the d/l will create a boot test
floppy for memory testing
3. I had problems with my 503+ and cheap quality memory, had to buy
"good stuff" from Crucial to get rid of the problems. One way to test
this is to run the memory at 66 MHz and the cpu fsb at 100 mhz.

1. I am using 95 fsb which is ok with me. I believe that when I used
this chip on my 2013 it would not work with 100. I don't see but that
may be only my ignorance, why memory should be effected by the multiplier
my weak logic says the fsb is the controlling memory speed. Is that no
so.
2. The memory is already crucial. Will try the test (my cycle time for
fooling with this machine is about a week) It is a collegue's who lives
some distance)

3. Would appreciate any comments about disk controller and cpu speed on
the 503+
Thank for the suggestions .

Heh, well, ya tapped me out on the other suggestions, no idea about
that disk controller, except that the fsb will have no effect upon
it's bus interface to the cpu (except that 95 MHz fsb will give you a
PCI bus speed of 31.6 MHz which is very much within spec). You have
already identified why the CPU does not work at 100 MHz fsb.
