I've read about this on several forums and decided to give 'er a go. I used a seam ripper to pop the resistor off. It took very little effort... lets hope everything goes well when I fire 'er up.

Below are some before and after pics.

What does this exactly do for you? Sorry, I haven't read up on this thanks. Also, how are your results after doing this?

I'm waiting for a replacement bios chip... should be here monday (fingers crossed).

Follow this link for the anticipated results

At the stock Vcore the processor is approximately 0.15v undervolted with the resistor on. By removing the resistor it is suppose to fix the problem which should also help the system posting at the limits of overclocking.

Hmm, now vcore is overvolted :confused:

What are your overclocking results after this mod?

Undervolting won't prevent cpu posting wereas undervolting will. I was able to hit 2.7ghz with my 4200+ with a new power supply so I'm hoping I'll get to 2.7ghz Super PI stable.

I'll let ya know when I get back up and runnin' with it...

You mean Overvolting first, then Undervolting... right?

Well as soon as your system run SuperPi from start to finish... could you please run the test at 1M and then 2M and take a picture, also put CPU-Z right next to SuperPi after each test to see how good your Manchester performs at this test.

My 3700+ @ 3.02 ghz runs 1M in 27.84 sec and 2M in 1 min 4 sec... I expect your 4200+ to be quicker, but if its not its nice to know my San Diego still beats dual cores at something... hehe :sweat:

K, just got my replacement bios chip from Tmod (tx bud) and check the voltage in Windows! WooHoo, bang on the set voltage!! :nod:

is this possible with an nf4 board?

hmm, donno. Is there an undervolting problem with the nf4 boards?

well there is no software that reports the right voltage, some ppl beleive that they are overvolted and some beleive that they are undervolted.

From experience not a single motherboard out there in the world has exact vcore voltage adjustments... just happens that DFI vcore is constant, not a zig zag heart beat type like others (hello Asus).

Thats just the software not reading the voltage correctly.. On every NF4 Ive tested with a dmm the vcore was right on or dam close to what I set it bios..
