GIGABYTE GA-Z87X-OC + USB voltage problem
« on: May 24, 2014, 09:28:40 am »
Hi guys, so i have:
GIGABYTE GA-Z87X-OC
Intel Core i7-4770K, 22nm, Haswell 3500MHz
8Gb G.SKILL F3-17000CL8D-4GBXMD
WD VelociRaptor WD2500HHTZ 10000rpm,64mb,SATA 3, 250Gb
WD Caviar red WD30EFRX 7200rpm,64Mb,SATA 3, 3Tb
WD Caviar red WD30EFRX 7200rpm,64Mb,SATA 3, 3Tb
WD Caviar green WD20EADS 7200rpm,32mb,SATA 2, 2Tb
Corsair CMPSU-1000HX 1000W PSU

The only thing 'overclocked' is RAM, which is set in bios as rated (manually) for 2133mHz, 8 9 8 24, 1.65V, rest is set to auto, all power-saving crap is off.

My problem is that i have 2 midi controllers which feeds it's power through USB of motherboard, so it's already pretty intensive i guess, but now i have new usb audiocard RME Fireface UCX which transfers pretty heavy data thorugh usb.
But time to times it have crackles, i'm absolutely sure that i've checked and double-checked everything about latency, MMCSS, ASIO and stuff like that that connected to card itself, it seems from manual of card and some chat with devs that it can be caused by not enough voltage powering to CPU / bridge / USB hub...

And i suspect it's last one.

So since i'm not very familiar with how Z87X bios settings about south bridge voltage (or it's analog of it from X58 era, coz now it's probably integrated to CPU as north?) or USB hub itself..

Any help of raising a little bit voltage on USB to check my theory would be highly appreciated! :)
