El_Capitan Posted June 28, 2012 Posted June 28, 2012 Updated 12/12/2012Hopefully this helps someone. I mostly followed this guide: http://rog.asus.com/46212011/rampage-iv-motherboards/rampage-iv-extreme-uefi-bios-guide-for-overclocking-2/These are my settings with BIOS 3301(different BIOS update may affect your overclock). Keep in mind, these are high overclock settings with my CPU, Motherboard, and Graphics cards cooled using a custom watercooling solution.Do not attempt these overclock settings with air cooling.This is for my 4.8GHz Overclock.Extreme Tweaker settings:I have a mix of 6 x 8GB G.Skill Ripjaws X's and 2 x 4GB Samsung Extreme Low Voltage RAM. I keep the timings at the default timings for the G.Skill Ripjaws X's.CPU VCORE at 1.39 during load using Prime95 will report in CPU-Z 1.440 - 1.448V's with my Load Line Calibration set to Ultra High. It idles as low as 1.416V's in CPU-Z. This may be reported differently based on your CPU, Motherboard, Memory, BIOS, and/or settings. I have two systems nearly identical, and they report things slightly differently. You don't want to chance anything higher than 1.4V's for supposed degradation, but I've not experienced degradation, yet.VTT CPU Voltage needed to be increased to 1.2V's for better stability to my memory and graphics cards.2nd VTTCPU Voltage doesn't need as much of an increase, I keep it at the 1.16997 to prevent 0x09C BSOD's. Not sure why, but it's helped prevent it for me.CPU VCCSA Manual Voltage at 1.2V's is enough for 58GB's memory at 1866MHz helps.DRAM Voltage at 1.515V's even though it only needs 1.5V's. I add 0.015V's for compensation.CPU PLL Voltage while I could go as far down to 1.55V's on my SB system, it's probably more reliable to keep it at 1.8V's.PCH 1.1v Voltage doesn't need to be raised unless you have multiple high-end graphics cards and also overclocking them.It's optional if you want to disable CPU and PCIE Spread Spectrum.I manually set CPU Ratio to 48 and leave everything else alone.I prefer my CPU Load-line at Ultra High rather than Extreme.CPU Current Capability I can set at Auto or 120% for 4.6GHz, 130% for 4.8GHz, and 140% for 5.0GHz. I set mine at 140% at 4.8GHz.CPU Fixed Frequency Manual set at 350.CPU Power Duty Cycle set at Extreme.CPU Power Phase Control set at Extreme.VCCSA Load-Line Calibration set at Extreme.VCCSA Current Capability set to 140%.VCCSA Fixed Frequency Manual set at 350.DRAM-AB Current Capability would be fine at 100% - 120%, but since I've got a lot of memory, I set it at 130%.DRAM-CD Current Capability is also set at 130%.I believe the only thing I turn on is Intel Virtualization Technology, and currently that's default Enabled. If you don't have a need for it, you can leave it disabled.I use Virtualization Technology, so I keep the Intel ® VT-d setting Enabled. Leave it disabled if you have no need for it.If you have an SSD, then use ACHI Mode. If you don't, then IDE Mode is fine. If you want to eventually setup a RAID array, then choose RAID Mode.Just my personal preferences for Boot-up settings.Anyone have any questions or suggestions for improved settings, let me know.

ccokeman Posted June 29, 2012 Posted June 29, 2012 Why are you hitting the PCH 1.1v so hard? Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted June 29, 2012 Posted June 29, 2012 (edited) Why are you hitting the PCH 1.1v so hard? I was getting random BSOD's due to my graphics card overclocks. I adjusted everything I could think of one at a time, and the PCH 1.1V and VTT CPU Voltage was the culprit. I could probably bring my PCH 1.1V down a little bit more. Testing for stability using the optimal voltages take a while with random BSOD's. Updated, I turned some Digi + Power settings down.

El_Capitan Posted June 29, 2012 Posted June 29, 2012 Hah, my changed settings weren't stable. Share this post Link to post Share on other sites More sharing options...
ccokeman Posted June 30, 2012 Posted June 30, 2012 VTT is going to give you stability to a point. To high and you get the same issues. Thisnkgs I have seen and heard include high PCH causing stability issues and drive corruption. Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted July 17, 2012 Posted July 17, 2012 (edited) I have been completely stable after raising my VTT CPU Voltage up a bit more (no more random-like reboots, even though stress-testing was fine). I've yet to lower PCH 1.1 Voltage. So far no issues going that high. Once I have my back-up system up, I'll mess with my settings again and update the OP. 158 hours running non-stop: Edited July 17, 2012 by El_Capitan Share this post Link to post Share on other sites More sharing options...
d6bmg Posted July 18, 2012 Posted July 18, 2012 ^^ Awesome results. 158 hours? Don't you even restart your PC once in a week? Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted July 18, 2012 Posted July 18, 2012 ^^ Awesome results. 158 hours? Don't you even restart your PC once in a week? Not if I don't have to. Usually Windows updates or some other updates make me need to reboot. Otherwise, I keep my computer on 24/7. Share this post Link to post Share on other sites More sharing options...
