Hey guys. Need your experience on this.

I recently changed to Win7 in order to try to get a stable build for my 5 GPU rig.

I'm using 5 AMD RX480 GPUs on this rig with Driver 16.9.2 and it looks very stable so far. The only problem is, the driver doesn't seem to recognize a 5th GPU, it only sees 4 of them.

I know that the issue is not a bad riser or the Motherboard. I had been able to run 5 GPUs on Win10 before but it eventually crashed after just 30 minutes or so. The difference was that I was able to hook up al 5 GPUs before.

Now, Windows7 can see all 5 cards on Device Manager, also I can see all 5 with GPU-Z. It seems that my problem is that I can't get the driver to manage all 5 cards. Wattman and can only see 4 of them.

Any ideas on how I can fix this?

try hooking a monitor too it or use a dummy plug
also disable ulps
also it can be risers that caused your crash as those super cheap cable version non usb types are garbage and can cause instability you want shielded or better
also those above cant take much flexing as they are shitty soldered pos risers
some of the powered types are even worse and sometimes they solder the positive/negative leads and cap backwards=POP so if using those types always check them 1st before using
this is for both the 80wire and 40wire types
