I have solved the problem. It's very simple. DND had already betrayed the correct approach. Just open the php.ini file in the folder C: \ Winginx \ php54 and put in the line 631 (approximately) this: extension = php_memcache.dll. Restart server and memcache runs. memcache does not need to be installed separately, since Winginx everything already brings.
I hope I could help you.
(sry for my english ...)
