Bios Setting: i7 950 and GA-X58A-UD3R (rev. 1.0)

CPU: Intel Core i7 950 - 3.06GHz Stock Heatsink
Gigabyte GA-X58A-UD3R Rev 1.0
Video: Sapphire HD4890 OC
PSU: Corsair 650TX EU
HDD: 1 TB Seagate Barracuda 7200.12

I just update the bios to F6 from F5 because weird Red Blinking LED on every boot.

F6 Bios Settings:
CPU VCore: 1.2V from *1.3V* Why F5 and F6 Bios auto default 1.3V?? i cannot OC until i get a better cooling so i keep with stock speeds.
Memory voltage: 1.66V from 1.5V default - needed for 1600 RAM right?, cannot pick 1.65V just 1.64.
VTT/QPI - 1.315V from 1.175V default - i get this change from oczforum for set RAM to 1600 from 1066MHz, but its good? i wish someone can help me to set the correct values on bios to properly use of the RAM.

DRAM Config:
Speed Default: 1066 - so i change to 12(1600MHz) and 8-8-8-24 (CAS-TRCD-TRP-TRAS), tRFC to 88 and Command Rate to 2N.

the good no more blinking red led on CPU LED-AREA, but the 3RD(L3) LED of CPU Voltage AREA and 2ND LED of DRAM Voltage AREA turns Green-Yellow, there is a way for these LEDs turn-off??? idont like much see that green-yellow lights ON, i feel like something is wrong on the mobo,cpu,ram.

  1. AUTO Voltage for Vcore is always high, I guess its to make 100% sure that your CPU will atleast post, You could probably run it lower that 1.2V, my Core i7 960 will run at stock speed with just over 1V.

    Your Memory and QPI voltages are perfectly fine and safe, You could most likely get away with 1.64V for DRAM. I wouldn't recommend going much over 1.355V for QPI.

    The LED's on your motherboard are just there for a visual indication of the voltages you've applied, and much to my annoyence you cannot switch them off! My Gigabyte GA-EX58-UD5 is lit up like a Christmas tree, Thanks gigabyte :(
  2. no i know the v cores i have to run at 1.28vcore for 3.6ghz my old bios i could run 4.33at 1.38
    i just need to know how i can get my old bios back?
