A simple Overclock for the Big Bang X-Power
« on: 17-April-11, 06:44:17 »

Here is a very simple overclock configuration you can try with the Big Bang X-Power motherboard that should work for anyone even if it's your first OC and give you better performance than OC Genie.  It uses a couple of tricks using some features on the Intel processor that are typically never used for overclocking yet they provide some interesting results with a locked i-7 processor like the 950.  If you have one of the more expensive unlocked processors like the 980x then you can directly set the CPU Ratio to 25 and leave the EIST, C-State and Turbo settings disabled.  Of course, most people buying unlocked CPU's probably know how to OC but this is an interesting trick for the cheaper locked processors.

This will give you an OC that runs the CPU at 3840/4000 Mhz with RAM at 1600 Mhz, Uncore at 3200 Mhz and QPI of 5760 Mhz.  Here are the settings:

For unlocked CPU's (e.g. i-7 980x):
CPU Ratio = 25
EIST = Disabled
C-State = Disabled
C-State Package = Disabled
C1E = Disabled
Turbo = Disabled

For locked CPU's (e.g. i-7 950):
CPU Ratio = 23
EIST = Auto
C-State = Enabled
C-State Package = Auto
C1E = Disabled
Turbo = Enabled

For all CPUs:
CPU Base (BCLK) = 160
Overspeed = Disabled
OC Genie = Disabled
DRAM Timing Mode = Auto
XMP = Enabled
XMP Mode = Expert
Mem Ratio = 5
Uncore = Auto
Set both VDroop settings = Low
Leave all voltages set to Auto
Spread Spectrum = Disabled

All other settings can be left at the defaults (including APS) except as needed for your particular drives and other hardware.

This particular configuration of C-States and other settings puts the CPU in a mode where it only uses the Turbo mode multipliers of 24 and 25 for the processors normally locked at 23.  Using 160 as the CPU Base gives you the clock required for 1600 RAM while leaving the clocks and multipliers unlocked with XMP Expert mode so the CPU can run up to 4000 Mhz on the 25 multiplier without having to mess around with the voltage settings.  

Clearly you can get a much higher OC out of this board once you learn how to tweak the voltages while maintaining the proper cooling levels but this will give you a decent 4000 Mhz OC with DDR 1600 that should be stable for most BB X builds as long as you have a quality power supply and decent RAM.  This is much better than you will get with OC Genie plus you can get some experience with the OC BIOS settings without having to worry about voltages or temperature issues (assuming you have a minimally reasonable cooling system).

You can also experiment with setting C1E as enabled to reduce temperatures when the system is idle.  When C1E is disabled the system will only run at 3840/4000 but when enabled it will run at 1920/3840/4000.  The multiplier switching happens so fast that I haven't seen any difference when benchmarking this but when you are at the Windows desktop reading web pages or whatever it will run at the lower speed which keeps the temperature and power use lower.

Let me know how this works for you if you try it.

Wow! The title of the thread pulled me right to it for a quick look. Thank you very much Dilburt. This will no doubt help those out there who are in the same boat as I was just a few weeks ago. My RAM is running a bit below 1600MHz speed @1583MHz, I think. I have the i950 and it's running at 4.12GHz, stable...so far. I visit the forum everyday even though I achieved my 4GHz OC goal. I don't post responses to Big Bang X-Power help posts because I'd rather leave that to the experts. I'd figured it would be best for me to read the posts/responses like I am doing now and keep on learning, keep on learning.

Cheers!

Congrats on hitting your OC goals.  It's all about learning and it sounds like you've already learned more than many people because you dig for the information you need and aren't afraid to jump in and solve problems by yourself.  You shouldn't be shy about helping others with the things you've learned.  This isn't a forum of experts, just other users like yourself.

Thank you for the encouragement Dilburt. I tried to help a couple of people here who wanted help with Overclocking their i7 950 and Big Bang X Power. https://forum-en.msi.com/index.php?topic=146322.0
I also followed your suggestions and tried your settings for my set-up and it works great! OC Genie gave me 3.76GHz, but the voltages were a little high. I saved your OC profile settings in the BIOS for future reference.
Below are some pics using your reference settings.

These settings also keep the temperatures low and provide good performance results for simple, no-fuss settings.  Have you noticed it running at x25 and 4000 Mhz whenever it's under load?

Yes, absolutely. The settings you posted are truly a "set it and forget it" BIOS settings for just about any novice overclocker. One just needs to read carefully, follow directions and in one shot, they have a stable overclocked system. Nicely done Dilburt.  :biggthumbsup:

I need help. I don't see any XMP or XMP Mode in my Bios. Please let me now if I need to change a setting to see those two settings. Thanks, from Bluesman
