1.75vdd mod almost 100 % failure!!!

[cgk123]

i did the mod perfectly with micro grabbers and a 1k pot set to 1014 ohms and showed 1.76 vdd in pc health and mbm 5 but the fsb increases did not materialize at all

215 was stable before and 218 was corrupting and after the mod 220 was not stable and corrupting also, maybe 218 would have worked but whats the point?

maybe its my memory or cpu? i am running pc 3200 micron and an xp 1700 tbred b

is there anything else i could have done wrong?

For one thing you cannot read the vdd voltage in the BIOS...so I'm not sure what you were looking at. Second, a 1k pot is way to small. You need something closer to 4.8k, so a 5 or 10k pot or VR is waht you need.

not to be rude or anything but you dont know what you are talking about.
i can definitely read my vdd voltage in 2 different places, in the bios; in pc health and on post; pc health and with mbm5 in windows
secondly its well established that a 1 k pot is exactly what i need, a 10 k pot would not raise the vdd at all cuz if you wanna raise it higher than 1.75 vdd you need a 560 -800 ohm resistor

why isnt my sig showing anyway?

Sorry....you didn't indicate the mobo anywhere and I assumed it was an NF7 (which seems to be the hot vdd mod topic of late).

cgk123, don't know why your sig isn't showing. As far as the vdd mod, not sure why you didn't get much of a boost out of it, other than you were already so high to begin with. 215 w/o the vdd mod is pretty extraordinary.

PiLsY, in his consolidated 8rda vdd mod thread (http://www.xtremesystems.org/forums/showthread.php?s=&threadid=8626&highlight=consolidated+8rda) had the following table that I think is relatively consistent with what I've seen posted:

1.58v = 196mhz DC / 202mhz SC
1.625v = 200mhz DC / 207mhz SC
1.68v = 206mhz DC / 212mhz SC
1.75v = 210mhz DC / 216mhz SC
1.81 = 213mhz DC / 220mhz SC
1.88v = 216mhz DC / 222mhz SC (222 I believe is the limit of the corsair stick I was using to test @ 2.9v. This stick does 226mhz at the same volts in an intel system)
2.0v = 218mhz DC / 222mhz SC (and a fairly warm northbridge heatsink)
2.2v = 220mhz DC / 222mhz SC (base of the NB heatsink was BURNING hot).

Your current FSB is still better than most at your current vdd. What is interesting and perhaps the better question is how you were able to get as high as you did without the vdd mod.

cgk123, lay off the caffeine !!!
