Blizzard 2060 memory problem

[hese7]

I have a Blizzard 2060 accelerator installed onto an Amiga 2000 with rev 6 motherboard and kickstart 3.1.
For some reason the Blizzard does not detect any memory installed onto the accelerator.

When I boot to AmigaOS 3.1 all I see is the CHIP ram.
I have tried different SIMMs (4 MB, 8 MB, 16 MB) but none of them seem to work.

Other parts of the accelerator seem to be ok.
cpu060 detects the 68060 ok and I get the correct autoconfig ID at the boot menu.

Any idea what could be the issue?
Broken accelerator or motherboard?

No, according to the Blizzard manual no jumpers are needed to set on the accelerator or motherboard.
And there doesn't seem to be any jumpers on the motherboard that would affect this (http://www.amiga-hardware.com/showhardware.cgi?HARDID=17).

I bought this used. The seller said the accelerator worked when it was shipped.
I'll clean the connector and check the SIMM slots and the motherboard.
Strange that the accelerator works partially, CPU operates okay.
