chkcache always takes a lot of time, if you have a alot of memory... And 32MB is quite a measurable amount.

The results are fine though. What I'd roughly expect from untuned average DX4-100. Your WB is disabled, but cachechk doesn't test hat.

You can use "-q" or "-qq" arguments to let it run faster with some impact on accuracy.

Ok then (Im happy you say the numbers are fine), I thought it was quick when I watched an LGR episode on Youtube. Probably it was just a cut/edit there 😀

Thanks - seems my computer reports White through cache in CHKCPU even though I change Internal Write Cache to enabled.

In order to get WB working you primarily need to move a few jumpers on the motheboard.

In the chart inside the case (Unisys ELI 4663) there is some info about jumpers but nothing about Write-back. Not sure the mobo supports write-baack?

CACHECHK takes a long time to run 30 times, as it does by default. Use a parameter for quicker tests: "cachechk -t6"

There isn't anything indicating wb support on that schematics.

There are three of four extra CPU pins that need to be wired to chipset in order to support the WB and vast majority of motherboards with support have several jumpers for that.

If it is the same system as in this thread, then you'll probably find more information printed on the motherboard.

Look for settings for P24D and keep voltage at 3.3V as it is usually the closest unless there is a direct setting for DX4-WB or Am486DX4 Enhanced CPU.
