BD7II voltage prob

[bibus]

Hello I got a BD7II with my p4 2.4B and oced to 2,9 no problem with voltage maxed out in bios ....
And that s only 1,65 even 1,63 on load .I bought a swiftech mcx4000 with delta 80mm fan monster ,hoping
that i ll join the 3ghz club ...but actually my temps went down about 8 c but still i cannot oc more.
I was wondering if others bd7II user could tell me what is their max voltage with this mobo , i know it undervolts,
but still 1,63 on load is very poor... I m pretty sure i could get to 3ghz wtih only 1,7 v but I don t wanna do the pin trick
as I m pretty sure that is why snds will occure. Is there any modded bios or any other trick to get up to say at least 1,7v
??? I m so ****ed off ,that i spent 80$ on my swiftech resulting in a total flop . Can it be done or should I sell the swiftech MCX4000 ...

Would a mister Natural bios do the trick , I ask before trying cause
I don t like to mess around flashing the bios too often, I already flashed the last one from abit ...

Mr. N's bios will NOT give you any more voltage on the BD7-II. Sorry.

 

[bibus]

Thx , but anyway what max voltage do you get with the board ?(was just thinking that mr natural bios would reveal some hidden settings for vcore ...too bad it doesn t , so i actually don t know the point of using it ...
)

HI there mate !
Well looks like we have the same problem
I make my own watercooling setup just to be able to o/c fine and bought some more RAM 100 €. But I'm still held back by the lack of Voltage
I asked around and everything but it seems to be impossible to make any such option in BIOS ( upping Voltage and stuff ) [ I mean for our mo/bo ]
Some good folks had it checked but couldn't find "any room for changes"
So I guess our only chance is to do some modding and I don't dare to do it. In my case I have an 2.26 that I can run stable only at 170 FSB And I know it can go higher!!! I got up to 3.05 and almost got in Windows (BSOD) and I know that it wants some more V!!!
I have precisely same Voltages as you do !!!
Well if you find ANYTHING please post it here !
Good Luck !

thx good luck to you too ...hope that there is a way beside pin trick ...i ll keep you informed if i find something , hope you ll do the same thx...
ps : the cpu even posted at 172 fsb ...but is not stable even at 165 without voltage mod ....damn

I do not know of any mod to increase the vcore but the pin trick, which I have done. But, if you are interested here's a link to a forum that shows you how to increase the BD7(II) vdimm with a mod. I'm tempted to try it on my board.

thx but is there a vmod for the vcore on the mobo ,as i think this is the main bottleneck ...

 

[bibus]

Isn t the pin trick very dangerous for the cpu ?
Can you set it at only 1,70 vcore ?

 

[ElroyCarbon]

No dude! I think the pin trick is way easy. Go into the TH72 area and look for a sticky from Batboy. I did it twice on two TH7s and it rocked. I could be wrong, but if it's the same vid pin trick you have 3 or 4 diff default options. I also just built last night my new BD72 RAID on a 2.53 and am running solid @ 3.04. The machine reboots just as I get into windows and crashed anywhere over 165 fsb so here I am stuck at least for now. My P4T533-C went up in smoke last night so rest in peace Asus and welcome 3.04GHZ!!!!!!!

Very easy to do

Go to this thread below: it has pictures for 1.70V

thx man I think i ll try it afterall ...

i know it undervolts, but still 1,63 on load is very poor...

I share your pain my brother.

My BD7-II undervolts something like this at stock voltage.....

BIOS: 1.50v
IDLE: 1.44v
LOAD: 1.41v

This is with a PSU that has a peak output of 650W too. I never had this problem with my old P4B266 - I got 1.50v idle and about 1.49v under load. This board sucks.

Here's a list of other gripes I have with my BD7-II....

Coz rants like a little baby.....
The most annoying problem I have with this board is that 9 out of 10 times when you hit DEL to get into the BIOS the POST screen is replaced by a small blue text line at the bottom of the screen and NOT the BIOS set-up. That one REALLY ****es me off!! When you're overclocking and trying to find the sweet spot you're looking at a LOT of attempts to get into the BIOS failing.

The other big problem I have is my RAM. I have some Kingmax PC2700 (5ns) which used to run fine at DDR352 2/5/2/2 (stock vdimm) on my Asus P4B266 but on this POS it's much worse than that. At DDR333 I can only run stable using 2.5/6/3/3 (Hi or Low strap) and it can't go much higher than about DDR342 no matter the vdimm or CAS settings!! Even when I take out one of the two 256MB sticks it makes no difference. When using 4:3 I can take the FSB right up to at least 177MHz (3.01GHz) but with 1:1 it doesn't go much past 171MHz. I don't understand why the memory is so pathetic on this board and was so good on the P4B266???

Man, I HATE this board. As soon as the Asus P4G8X (E7205) is launched this board is gone.

 

[bibus]

can i use a fan wire to do the pin trick or is it too big ? sorry for that dumb question ...so what did you use ?

Well you got lucky and I didn't
Nice o/c !!! What is your 3D Mark ???

Crapped out with3DMark @3000Mhz
Had ta knock it back to 2800Mhz
Score .. 14075

Yes I do think i did get lucky.. Touch wood

 

[ElroyCarbon]

I scored 14,700 with mine, but I think the 9700 Pro had alot to do with that.

3.040 and Corsair XMS3200
