I have the same combination.Quote:

I think there is a bug or cpuZ is showing the exact value under load :confused:
I tested with CPU-Z, WCPUID and a realtime clock of WCPUID. Beneath 250MHz it measures the frequency correct all the time - idle and load. 251MHz to ~260MHz WCPUID + the realtime clock measures correct and the CPU-Z keeps falling under load... at 270MHz and up WCPUID measures a FSB of about 20-30MHz beneath of what the frequency is set - the same idle and load where CPU-Z measures the full frequency idle and drops a lot load.
I suspect it's the PCB.... seems like they used the same for some of their 915P boards wich should be limited by 10% overclock and with the trick Asus made 25% wich would be 250MHz. I can't confirm this, but I have verifyed the performance is a bit random above the 250MHz - the frequency IS unstable.
You're lucky you have a 3,6E - 18x250=4500MHz before you run into problems... I allready do at 3500Mhz and there is more in this CPU!... of course you will loose some performance because you can't take advantage of the CPU Lock Free feature and gain high fsb...
I do not have problems over 250mhz!!
You are conneting a VR between pins #17 and #18 for this mod.
I marked the specific pins in one pic and pointed out a place you can solder.
As far as the lower place in the pic on post #1, I dont know if that resistor end is connected to pin #17 or #18, so thats why I pointed out the ends of the capacitor.
If you are worried about soldering there due to the fact that you can accidently solder a few of the pins on the ADP3180 together, do a connectivity test between pin #17 and the surrounding resistors/capacitors/solder pads until get a hit. Then do the same for pin #18.
Carnaby...
Did'nt your clock frequency drop while running that SuperPi? CPU-Z measures fine when the CPU idles... when it loads the frequency will drop. Can you confirm it measures 261Mhz FSB while loaded 50/100%

Vmem Mod
What for a Resistor? Voltage?
Aquaman,
that is the Vdimm=Vio mod (Vdimm = 3.3v rail off the power supply).
You dont use a resistor (typically) on this mod, and the ram is receiving the same voltage as the power supply has on its 3.3v rail.
With a Resistor from 1k Ohm, and you adjust to 0.9k Ohms, the Voltage is 2.97V. Is that correct?
I dont know the internal resistance for the Vio, so I dont know the effect of adding an additional 1K resistor will have on the output voltage to the dimms.
I am not sure that a standard resistor will hold here either. The current may be to high.
What are you offering for the variable Vdimm mod?
Can older p4p800 mod be used?
anyone tried?
OK, although there is no LM358 on P5P800, there is no other way that I can find for Variable vdimm mod.
First I made the vdrop,
and then the 3.3 rail for the vdimm.

It's fine, now I get more stable oc clocks for cpu, and 225 fsb 1:1 dual 2-2-2-5 timings for my TCCD rams at 3.6V. :D
meke, is the vdrop mod same as the droop mod? can u mark the spots where to solder please? i cant see the resistors where you soldered them to very wall. help would be very much appreciated!
Yes, Vdrop is same as Droop (Vdroop).
There is some ways that I can get some more photo, but my advice is;Quote:

you can find them around the components that I pictured.
Believe me, it's easy. :toast:
oh ok, thanks! wouldnt hurt if you could post more photos :)
hope this helps :rolleyes:

yup!!! thats perfect! thanks mate :) now all i have to do is solder... lol
just for surety's sake... theyre the resistors with the red circle right?
http://img117.exs.cx/img117/3604/m7svdrop2.th.jpg
yes they are, but please be sure that the e-multimeter beeps for the short circuit.
do not solder before you are sure!
Yes this really works.
before the mod, it was only possible to;
275 x14 air
220 x 18 air
295 x 14 wc
225 x 18 wc
superpi 1M 31 secs.
after the mod ;
290 x14 air
225 x 18 air
300 x 14 wc (nb needs vagp mod :mad: )
240 x 18 wc
superpi 1M 28 secs :banana:
http://img.photobucket.com/albums/v2...perPI/28sn.jpg
and 300 fsb :toast:

thanks again man, pretty nice sPI times... :)

BTW, you will get 24 or 25 secs if you patch the superPI :banana:
200<-->250Mhz With Water Cooling full bench. Temp Water +10° Vcore 1.5v from bios....real vcore is 1.58v (vdroop)
250<-->263Mhz With Vapochill Cooling full bench.Vcore 1.5v from bios....real vcore is 1.58v
263<-->278Mhz Max Oc only for Spi and screen(not stable)
