    I brought down my tRFC and static settings and it's still stable @2.2v.

    I got MCH down to 1.32 with CPU ref @.76 and MCH @.72. Now if I want to move my VTT lower will I have to readjust my MCH ref since VTT voltage has an effect on it?



    Update: I brought down VTT to 1.32 and MCH to 1.32 with references at .73 and .72 and it seems to be stable.
    But, I enabled RAID in the bios and I can't get Windows to boot. I haven't put the extra drives in yet, I simply turned on the option in the bios.
    I went back and turned RAID off and I started to add drives one by one. I'm getting the same boot failure when I get up to 3 total drives with RAID turned off.

    Have you ran Prime95 or IBT? What are core temps during stress?

    Can you post your full settings, preheps a screen capture of EasyTune advanced voltage tab and MemSet main window too?

    Sorry I am not familiar with RAID, can't help with that.

    I had the same problem with RAID0.If you don't have your HDD's installed and Raid set in BIOS before you install OS you'll have to do a clean install. Anyway thats what worked for me.
    My other RIG is a EP45-UD3P rev 1.6 FE / E8600 - 4.27GHz (450x9.5) LLC:Enabled / Vcore:1.36875 / Vtt:1.36 / CPU PLL:1.57 / CPU Ref.:Auto / MCH Core:1.26 / MCH Ref.:Auto / DRAM Voltage:2.1 - yours may be different. You might work on reference voltages to get Vcore and Vtt lower. I'm not trying to step on anybody's TOES here - LSD was helping me with these settings - But he left forum before I could get 24/7 stable. I'll just sit back and watch from here on out.

    These core temps are after 5 hours of Prime95 with 23c ambient. It's stable with these settings, but I get an error in Prime95 after a few hours if my extra HDs are installed.
    I had to raise my ICH I/O and ICH core up to get it to boot with the 4x1TB WD drives. Still no luck with the raid setting. I run a RAID 1 array so I'll have to install my OS again anyway.

    I'm still working on getting vcore, VTT, and MCH lower. The settings below are as low as it will go with the current CPU and MCH reference numbers.

    Hey wibujo everyone are welcome to share their experiance, it is not considered stepping on toes :-)
    Does your other setup also has 8GB of memory or just 4GB?

    I'm not sure what happened here. I was adjusting my vcore and now this is what I'm seeing in ET6. All of my bios settings are exactly the same as the last post. I reset the bios back to optimized and started over and I'm still seeing the same levels in ET6. My temps are higher and Prime95 gives an immediate error.

    Looks like adding the raid array is what caused the issue. I took out the raid and put the single drive back in and ET6 shows the right numbers.

    Why would adding two raid drives in place of a single drive cause the voltages to move like that?

    I'll take a stab at that-- the raid drives are holding the configuration (back up) bios?

    Chike, I just got back in town. My EP45-UD3P / E8600 is running 8GB of G.Skill (4x2gb) F2-8500CL5D. I wish my EP45T-USB3P / Q9650 was as easy to OC. My E8600 seems to handle more voltage. It ROCKS!!!

    BIOS Settings are not on any Drives.

    Are you still having voltage issues you think are RAID related? If so please explain because this is not possible, so I will let you know what is causing whatever you are seeing as a voltage/RAID issue
