Solved Vcore only option is 'auto'

December 31, 2013 at 07:51:27
Specs: Windows 7, C2D 4600 w/ 3GB DDR2-5300
Hi all, I hope you're having great holidays!

I replaced my C2D e4400 cpu with a C2D e4600 on my Asus P5LD2 board. In BIOS, the only vcore option now is 'auto'. The advanced overclocking option is in BIOS is set to manual. E.g., I can change the MCH and DRAM voltages. Before, I could also select the Vcore voltage.

I want to increase the Vcore because I want to run the 'new' CPU at 3.2Ghz or higher (default 2.4Ghz). Without a Vcore adjustment, I can only get it up to 2.8Ghz.

I have re-flashed the BIOS - didn't help. I have cleared CMOS (both jumpers and removing the battery) - didn't help. I have googled for this issue but it doesn't seem typical for this board (or the CPU).

Does anyone have a solution? What could I try next?

Your CPU support list:
http://support.asus.com/cpusupport/...

"Core 2 Duo E4400 (2.0GHz,800FSB,L2:2MB,65W,rev.L2) 2.01G
1702 "

"Core 2 Duo E4400 (2.0GHz,800FSB,L2:2MB,65W,rev.M0) 2.01G
1902"

"Core 2 Duo E4600 (2.4GHz,800FSB,L2:2MB,65W,rev.M0) 2.01G
1903 "

You need version 2.01G motherboard and BIOS version 1903 for full support. If you have an older version of the motherboard,you might not get any better, even with the latest BIOS version. Sorry.

You have to be a little bit crazy to keep you from going insane.

AI Overclocking - manual
CPU Frequency - 266
DRAM Frequency - DDR2-533
PCI Frequency - 100
PCI Clock Sync Mode - 33.33
Ratio CMOS Setting - 12

If the VCORE Voltage isn't adjustable, try changing the AI Overclocking setting to AI NOS.

Happy New Year everyone!

Hi riider, thanks for your reply. Under AI NOS, also the only vcore option is 'auto'.

Hi Fingers, thanks.

According to CPU-Z, my board is revision 1.0, my e4400 is revision L2 and my e4600 is an M0.

So it seems both CPU's aren't even fully supported. On the bright side: I guess I can call myself lucky to be able to set the vcore for the e4400!

I'm going to put the e4400 back in.

Thanks for the research and a Happy New Year!
