I installed that card in SiS530 mainboard

If it's AT board, you're out of luck.

It's a very weak card. I was also disappointed by its performance. (Mine is the GT 610 but they are the same thing.) Note that it runs very hot and the thermal paste tends to crap out over the years leading to thermal throttling and other problems. You should replace the paste if you haven't done so already. Also consider replacing the passive HS with a proper HSF pulled from a cheap PCIe card.

I got less than 5600 points on a Geforce 210 PCI and a dual core Atom with Win 8.1 but I suppose these old bench and modern gpu simply aren't somehow comaptible to be rendered in the way and speed they were intended to like on older o.s. and on older GUI. For example things get even worse with 3DMark2000.

It's ATX board, Shuttle HOT-599 http://www.motherboard.cz/mb/shuttle/HOT-599.htm.
Maybe i should try putting more memory there, I only had 64 MB when I was testing it. I should probably also check if it's detected by Windows when using integrated GPU as main graphics card.

Actually it seems to be not working when I install it in that mainboard, entire system takes just 24 watts of power and obviously card is not heating up at all.
