M18x R1/R2 Sandy Bridge and Ivy Bridge CPU Overclocking Thread

[Mr. Fox]

Joce21 - select immediately, then select permanent, then after that select F10 or save and exit.

Not working, it still get disabled after reboot...

1. I enable Non-Turbo Flex support
2. I enable Extreme Edition
3. I set it to Level 3
4. Under Bus Clock I select "Apply Settings Immediately"
5. "Apply above settings :Applu settings immediately?" I press "OK"
6. Then I select "Apply settings permanently after reboot"
7. "Apply above settings :Apply settings permanently after reboot?" I press "ok"
8. Then I press F10 "Save and exit", went back in BIOS and it still disabled...

Did I miss something?

Just a shame that the HM67 didnt have "forwards compatability" to drop an Ivy cpu in....then we WOULD have been laughing lolol

Word is if the HM67 system has the ME 8.x firmware in the system bios rather than the ME 7.x for SB, then a IVB CPU will work. See my previous post. Need some pioneers to try it.

It sounds like you are doing it correctly. I don't know why it is not working.

Sounds exciting, but I'm too chicken to risk bricking my M18x. I'm not much of a pioneer these days. Parts are too expensive and warranty would not cover that.

Hi 1st time here.Had a question about overclocking the 3920.I have Intels XTU on my machine because I can adjust core current limit. The problem is everytime I try to go over 45 on 4 cores I get a BSOD.What should I have the settings in the bios at?Thanks

Hello, and welcome to NBR. Congratulations on your Alienware purchase. We are happy to have you in our Community.

This is because you need to increase volts and amps to accommodate the higher core speeds. It's probably a 0x124 STOP code. Try increasing FlexVID (volts) to 25 or more. If you still get the BSOD, you may have to wait for an unlocked BIOS to gain access to increase Pri-Plane (amps).

If you are a newcomer to overclocking, you may want to begin reading at the beginning of this thread so more of this makes sense. You need to change most settings in the BIOS. XTU is only useful for changing the multipliers and BCLK withing Windows. Amps and voltage changes cannot be effectively manipulated with XTU on the M18x R1, and probably not on the M18x R2.

This is the latest version of XTU,3.1. In the upper left it shows "core current limit" at 112.000A which is default.Isn't that the same as 896 PriPl? 125.000 core current limit=1000PriPl. Right next to CCL is "Additional Turbo Voltage" However when I attemt to enable Non-Turbo Flex support in the bios,as soon as I reboot and go back into the bios it's disabled.

[Mr. Fox]

XTU doesn't support FlexVID (voltage) or Pri-Plane (amps) adjustments within Windows on our laptops. It is only by a stroke of good fortune that it works at all, because it is not designed for our systems. Only BCLK and core multiplier settings will work with XTU. The main benefit of using XTU is to set multipliers higher than the limits allowed in the BIOS. Other than this, you should make all of the adjustments in the BIOS.

Is there a mobile version of XTU because the desktop version doesn't show much info or allow for any changes on my 2920XM.

I tried the forum "search" but as always, I just get a query error "Could not find phrase 'invalid_search_query".. Does SEARCH even work anymore? Seems i've not gotten any search results for known keywords for months!

Amen to that brother. The search is borked.

[Dreyer.R]

The latest version doesn't work with SB. Try 2.1 it worked with my 2920

No, there is no XTU for mobiles. You can use XTU to set multipliers higher than the BIOS allows and adjust BCLK within Windows. All other adjustments need to be made in the BIOS (FlexVID, Pri-Plane, etc.). We are very fortunate XTU works with our mobile systems. It is not intended to work. And, only XTU 2.1 works with the R1. Everything except BCLK is grayed out with the newer version.

As far as the search function goes, here is your ticket to paradise...

The forum search feature is broken. Use Google instead and it is highly effective. Start your search query with the prefix site:forum.notebookreview.com in front of key words. To limit the search to Alienware, just add /alienware (i.e. site:forum.notebookreview.com/alienware in front of key words).
