Vdroop pencil mod (HD pics and datasheet included!)

post #1 of 11
Thread Starter 
OK so here's the situation, Idle voltage : 1.372v Load voltage: 1.328v

This Vdroop is seriously limiting my OC, without this droop I reckon I could hit 3.8 or 4.0 GHz. OCN genii, help me!

I'm looking to pencil mod this, what do I pencil?

EDIT: I forgot to attach datasheet, fixed now

Can you check the pathway of Pin 17 and label it on to pic? I can just see the start clearly.
It is very likely that one of those 4 resistors is the one where you can use the pencil to reduce vroop:

OK, if no one objects I'm going to pencil this resistor:

[ATTACH]200098[/ATTACH]

I am going to pencil in 5 mins, if this is wrong tell me before then

EDIT:

OK just penciled, no change in Vdroop frown.gif

Testing stability right now just to make sure I haven't made anything worse.

If it's not the right run rub off the pencils graphit an try the other ones.
Your trace routing doesn't seem to be right. I guess you have labelled some adittional traces which lead to some other pins but not pin 17.

If you tell me what pins to lower the resistance between I'll try and figure the rest out smile.gif

Just have a look at the pic I've posted, there are 4 resistors labelled which are good candidates. You've tested one of them so there are 3 more to try smile.gif

Bump.

Did you isolate the correct trace and reduce your vdroop? The vdroop on my P45XE is much worse, at around 0.08~0.1v with my Q9650 overclocked to 4Ghz.

Thanks in advance.
