Unhappy Re: Poll: does PCI-E ASPM work for you?

I always have ASPM disabled regardless ASPM policy which is now:
cat /sys/module/pcie_aspm/parameters/policy
default performance [powersave]
That's really strange as I have quite a modern GPU (it supports PCI-E v2) and my motherboard is also brand new. In this topic there are people with older GPUs and ASPM works for them ... I have no idea who to kick for this problem and how to solve it - I guess ASPM should work for me.
