EX58-UD5 F13 mobo with F13 series bios has a worse dpc latency problem
when I use BIOS F12 , the DPC latency problem don't annoy me
when I update to F13 default, the DPC latency is very terrible almost about 40000us
Fresh install of win 7 only drivers installed. No ET6 or DES installed at all.
and then i try some methods, such us C1E disableed , EIST disable , windows 7 power option , HT disabled
,update divers ,................
they are useless , can't fix my problem
