Latitude E6520 Turbo Ratio Limits
#1
Hi, I have a fully unlocked i7-2920xm ES and am trying to overclock it in any way possible.

The BIOS has quite a few options, but none for setting turbo ratio limits or anything else. Could you please look into hidden options for things such as turbo ratio limits, BCLK, and turbo power limits?

I have tried setting the turbo ratio limit via MSR 0x1AD in windows, but the CPU ignores the change in the register. I have also tried changing the power limits register, MSR 0x610, but bit 63 is set high, which locks the register from accepting any changes.

If it turns out that there are not any hidden menus or options, is it possible to set these 2 MSRs somewhere in the BIOS? For example, add in a few lines of machine code to change the turbo ratio limits to 0x21212425 instead of the default 0x1F1F2122?

I can upload more BIOS pictures if you want. Note that PhoenixTool reports that the BIOS is Insyde based, but you can tell in the UEFI menus that Dell definitely made their own changes. I hope that this does not matter.

BIOS install .EXE: http://support.dell.com/support/download...eid=465781

BIOS backup .ROM if you cannot open the .EXE (note that this backup is version A05 while the EXE is A06): http://www.mediafire.com/?zzvayg3948zm855
