Ground

wich sofware or where is the part of the bios that i can see de vdimm ? :D :( :p:

Could this be why my E6600 is limited to 3.6Ghz stable?

Can i use multi wire cables? i got some that are easier to manipulate

1 wire are often harder to solder, but easyer to manupulate and VERY small.

You can use ANY thing you want, just as long as it conducts electricity.
And with multi whire cabels you just cut some of the end. Lets say 66% of the whires ;) That makes it alot easyer to solder because you make it so small.

Cant remember if BIOS has VDIMM monitor under "hardware monitor" if not, you`ll need to probe with a multimeter.....

possibly, tho i`d say probably not....whats your current MCH voltage?

thank you! :toast: :)

anyone know what resistance value the VR should be set to for the vcore droop mod?

i'm getting a HUGE droop (0.07 to 0.09 volts).

same here upto 0.09v vcore droop !

someone said pencil can be used for droop mod ? how exactly ? :)

thanks

Guys, you do realize that this motherboard undervolts from the get-go, right? From what I have gathered, it was usually anywhere between 0.05v (like on my board) to 0.07v, measured with multimeter. This is not vdroop, in case some are wondering, and vdroop mod will not fix that. For that you will need vcore-mod. Actual Vdroop can only be observed under full load and with a multimeter and its range may also vary - believe it or not on my board it's almost not noticeable.

Just in case, we're not on the same page... :D

Question:
When you do vmod .. Is it required to do the vdroop also?
I do the vmod (with 2 x 50KVR in serie mode) and vcore only dropped 0.01-0.02v...

Did you notice considerable cpu temp increase after vmod? I tested 3 chips and they all run real hot on my dlx. If I set 1.5 or more cpu starts throttling (all disabled in bios) at 85C+. This is on water, I keep it at 1.45V.

@B_A mainly..yea, i`m getting similar. Droop is almost zero, but Core and MCH voltages undervolt compared to BIOS quite majorly. VDIMM overvolts 0.05V

I know this is OT but just to say....thats mostly up to the chips, i tested 5 6600 all different weeks, in same case, same hsf, etc, just chips changed.

measured with core temp the hottest of them was about 75c at 1.45 and 3.4ghz at 1.5v and 3.5 it would go above 85c it was getting huge temp increases with just a little bit more vcore.......while the coolest one could run at 1.58-1.6v 3.5ghz and load was about 75c.........

the point is ya if you have a hot running chip it will get even hotter with a vcore mod

the vDroop mod helps a LOT.

Without vdroop mod: (resistance= 75 Ohm)

1,55v in bios --> 1,49v idle --> 1,46v stressed

With vdroop mod: (resistance= 15 Ohm)

1,55v in bios --> 1,54v idle --> 1,54v stressed

so do i need to vmod this board to get 3.6ghz with e6600?if so which board out there doesnt need modding at all to get decent clocks?

you shouldnt have to mod the board, no. 3600 is only "really" "pushing" the CPU, the board can handle 400FSB fine

Have I been really luck with my board? I dont feel theres any droop here, just a normal 0.01/0.02V fluc during idle/load switch points.

I also dont have the same extent of 4:5 RAM divider troubles as others :eek:

Should I use a 20K or 100K VR on the vdroop mod? I only have two 50k VRs. Will a 20K do on the vcore, vMCH or vmem mod too?
I need one of the 50K VRs for my 7950GT vGPU mod, so I only got one 50K for the P5B Dlx mods.. I got two 10K, two 20K and two 100K.

Anyone did the pencil vdroop mod ? Where to pencil ? It's like the p5wd2 premium ??!

You guys are really hot !

Mine 6400 28A is cooler :D, look :

CPU : 3540MHz ( 501fsb x 7 ) -> 66% de OC
Mem : 1002MHz ( 1:1, 501MHz, 4-4-4-10 )
vCore : 1,43v
vMem : 2,30v

( All other voltage settings @ minimum values )

Full temp : 50º/52º @ WC
Super PI 1MB : 16"

Anybody noticed sudden reboots when vcore is set above 1,85V?
My P5B-DLX always reboots after entering Windows when I set vcore above 1,85V.
Is there an ovp mod?

I guess no one wants to share any pencil mods.

still wondering about the resistance to set for droop mod.

i have a 50K VR in place set at 50K.

1.55 bios shows 1.52 in windows...

n/m

i just went into the bios... set it to 1.55... bios read 1.528...

adjusted until voltage went up... bios then read 1.536 and was stable... :)

Eny mods for asus P5B-E plus:confused:

same mods

Is this 100%,you try that mate,eny pic.
