K6 233(3.2/3.3v) on single voltage mb(3.3v) - award bios

The 3.3V Version is rated at 9.75A, the 7.5A of the 200 are for split-voltage 2.9/3.3V.

I'd stick with 200 MHz to be on the safe side, at max I'd use 75x3 (if the board supports 75 and is stable)

Just to keep you all updated on the BIOS issue, Space Marine is now running the REV:F10 BIOS. This is the latest official BIOS I could find for the Lucky Star P54CE Ver.F board and it is a close match with the original REV:F03 BIOS he send me.
This 02/14/97 REV:F10 BIOS has full support for the 3.2V/ 3.3V K6, but not for the later 2.2V K6 and K6-2 models.

Greetings,
Jan.

hey Jan, nice to see you posting here :) it's been a while..

support for the later 2.2v K6/K6-2 would require split voltage on the board. since it doesn't support split voltage out of the box and doesn't even feature a vrm slot there's no use in supporting those processors on a board like this anyway.

Hi Jan! Very Happy

My motherboard is dead!

I installed correctly the k6, it started but no POST done.
Then i returned to my p133 but no post too.

Maybe that mainboard was completely incompatible with k6.

Any idea or i have to launch it out of window? Sad

you have reset the jumpers properly? You did a cmos clear?

while running the AMD K6 you did install a large fan to cool the cpua AND the power-transistor, didn't you?

Today happened a strange thing:

i tryed another time to start the mb with 133 and it starts, and now it is running.

Onestly i don't know what happened, but i didn't changed nothing from when i reinstalled it to today.

However a moderate fan was installed, not directly on cpu and VRM where i use the old ones, but at about 5 centimetres.

I don't know if is a good idea to risk again on mounting the k6.

yeah and disconnect from mains power to be sure.

the VRM may have indeed overheated, it might be a good idea to put a large heatfinger on the power transistor on that and have a larger fan blow over it...

I don't thing that it gone overheated, i touched it just after the last trying (when it doesnt post) and was cold, like metal at ambient temperature.

I'm posting from the k6! It's up and running since 3 hours! Very Happy

The problem probably was that i hadn't cleared cmos.
I have installed old cpu fan on vrm and used an old gf2mx fan as cpu fan.

The case is opened: i can touch cpu heatsink and is still cold Smile

Vrm airflow seems a bit hotter then cpu airflow, but the difference is barely noticable, and in general is very little bit hotter then ambient temperature.

I'm thinking that probably it will not suffer much on setting cpu at 233 (original k6 speed) instead of 200.

However i have another question:
win95 recognize cpu as a general pentium, and not a k6 mmx (bios recognization is ok).
Does it influence performances much? Does any k6 mmx patch for win95a exist?
I'm not noticing big performance improvements from old p133.

Use Everest or Sandra to check for K6 featrures been enable or not. Especially this should be MMX and Write Allocation.

It is way faster than your old CPU not only because of MHz but also 'cause of quadrupled L1-Cache. (2x8KiB on P1-133, 2x32 on K6)

If you use Everest, please post a dump of the CPU MSR's.

To do this, right-click on the bottom bar, select CPU Debug, then K6 MSR Dump.

Thanks.

I'm using everest

- MSR dump is empty

- this is cpuid+msr dump
