OCZ 3700EB wont respond to higher Vdimm?

[brwmogazos]

Spent some time playing with my 3700EB modules in the last few days....

well my sticks aint the best clockers arround

max i can get them is 242mhz @ 2.5 2 2 5 (8) pat enabled, turbo, infinity, 64ìsec

At first they only liked mos of the settings to auto except 2.5 2 2 5 (4)

did some burning in etc and now i can see they can cope with all the other settings enabled

the prob is that the sticks wont respond to voltage at all

i am pushin 3.05V which is the lowest my board can do (Vdimm modded)

i am testing with memtest 95 and prime

from 3.05 to 3.35V I DONT GAIN even a SINGLE MHZ

thats with 2.5 2 2 5 always

i have taken their heatspreaders off and used 2 delta fans 40mm and coolermaster ramsinks to cool them

i tried last night dimm slot 3 and 4 which were worse giving me 4 errors in memtest at the fsb of 242

seen a mates sticks do 252 prime stable and memtest stable at the same timings and voltage.

if i try cas 3 and keep the other settings the same i DONT gain any extra mhz either...

even if you do try 3 2 2 8 still nothing

i slackened the timings to 3 3 3 8 and they did go higher(didnt find max)

any idea why they dont scale up with voltage + why do they not gain any extra mhz with cas 3 from 2.5?

My board is the asus P4C800E Volt modded
NB cooled with TT tiger 1 cooler
VAGP 1.75V iirc

cpu my 2.8M0 or the 3.2C i got a few days ago(been testing with both)
