"Green out" could be a LED going to the front bezel of your case.

What's wrong with the lever of your board? Iirc those white s3 ZIF sockets always had plastic levers, the metal ones came later?

The IBM 5x86 is basically the same as the Cyrix 5x86, but it was different from the AMD 5x86, so no idea if your chip will work in your board (it might, but not be straightforward).

The additional pins are probably for larger cache chips that are packaged in larger of those black cache plastic thingies and the larger cache thingies need more legs for them to work.

What does your manual say about mixing RAM?
I remember at least 1 motherboard with 30p and 72p SIMM slots, its manual (probably taken from TH99) wanted me to fill the 30p slots first (but sometimes the manual will lie).

- Do not bother with the power saving green features (switches or leds), no point
- according to the manual (http://www.elhvb.com/mboards/qdi/895p3s5.pdf) the Cyrix 5x86 does not yet exist, so it is not supported
- you can put 1024 type chips in the longers slots but then you have to leave the other four sockets empty. This means having 512 kb, non-interleaved cache. This is the offical ceiling of this motherboard. Then you can put 64 MB memory and have it fully cached WB.
For example: http://www.ebay.com/itm/ISSI-IS61C1024-15N-DI … KYAAOSwF1dUPhUF
. The BIOS chip might have a DIP32 socket but will always utilize the shorter, smaller capacity chips, so again, ignore that 😀

According to the manual, two legit arrangments exits for having 64 MB RAM, and the latter is preferable: where you leave the simm30s empty and use 2 Double Banked 32 MB FPM RAM pieces

I thought the same as you, but there are actually some Socket 3 levers made of metal (the Socket 3 entry in Wikipedia shows one). In any case, having a ZIF socket with a lever of any kind is a blessing compared to the awful "LIF" sockets that used to plague 386/486 motherboards... those things are made by the devil I tell you 😁

Another example: on my Biostar MB-1433/50UIV, it seems that you can do pretty much all kinds of combinations. However, on the MB-1433/UCV you should start with the 30p slots according to the manual. So it seems there is no standard way of filling the slots. I would guess the most important thing is to completely fill each memory bank you want to use.

I think it should be on par with the average taiwanese/chinese motherboards of that era, it was pretty much the wild west in terms of standards and compatibility so your mileage may vary, but unless it has some blatantly obvious problems such as fake cache or a subpar chipset you should be OK.

Yup, I know! 😁

Never understood what was so LIF about those 😵

LIF sockets were good for motherboard and CPU producers as they could sell more motherboards and CPUs due to broken or badly bent pins 😀

Later there came the idea to change the CPU socket with any next generation of CPU, which seemed a good solution to profit more after they made a serious economic mistake introducing ZIF sockets 😀
