I am so lost with this, i dont even understand why the cache is not even detected, since i changed the chips ans changed the jumpers

Well it does seem that only 8kb are recognized - see the ms jump from 11->42 after the 8KB mark
Check your motherboard, maybe there is a broken trace somewhere

The 8K is the L1 cache on the cpu. There are multiple options for your chips not getting recognized... wrong configuration, faulty chips, timing issues for example.
Maybe one of the sockets connections(or as already mentoned traces) is faulty albeit it's strange that the BIOS shows the cache size but speedsys doesn't recognize it. The only chance this can happen is when the L2 speed is too close to main mem speed which doesn't seem to be the case here.
Start speedsys and take a look at the diagram it plots.

I wonder if the BIOS only reports the value set by the jumpers without doing actual testing on the cache. What if you pull out the cache chips or the tag chip but keep the same jumper setting? Will it still report 256K cache?

What are the values you are using for DRAM and cache timings in the BIOS? I have a PCChips M921 board that doesn't detect L2 cache when using the default slow cache timings that are set by the BIOS Chipset auto configuration. I need to manually set it to a faster value such as 2-1-1 or else it is too close to DRAM speed like amadeus777999 said.

will post a picture of bios once i get home
maybe you can advise what numbers to put after that picture. because i have no idea whats going on with this motherboard.

OK guys here is a full set of photos, from bios, bootscreen and speedsys
if anyone got any advice i appreciate, this cache not being detected is strange to me

Your cache policy is in write back mode but tag ram is set to 8bit. Usually 8bit is for write thru and 7bit is for write back.
Also can you verify if your CPU supports write back mode?

Only 16kb L1 cache 486 Intel supports WB - like SK096. But I doubt this would have any effect on L2.

Double check the jumpers for cache.

What happens if you disable L2 cache in BIOS? What does System config reports at boot?

I don't think you mentioned anything about it, but what speed are your cache chips? 15ns? 20ns?

Anyway, you can try the following:

• Double check cache jumpers as kixs said, if in doubt you can post a picture
• In the CHIPSET FEATURES SETUP section of the BIOS, change Auto Configuration to Disabled
• Set Cache Burst Read Cycle to 1CCLK
• Set L2 Cache Tag Bits to 7 bits

it works!!!
i have changed those bios settings and ALso changed the cpu and also the jumpers to an amd x5 133

cache detected
runs like butter

Any chance you can share your jumper settings? Recently picked up a 4DPS and cachechk isn’t finding any L2 cache.

Disabling L2 cache has no performance impact on Quake. I’ve tried swapping in known good cache chips. BIOS says 256k on boot. I’ve triple checked jumpers.

Found a jumper combo that’s now working with the l2 cache. I don’t think the manual I’m referencing is accurate. I’ll post pics tomorrow.

Here’s the jumper settings I found to work for a POD83.
