I guess you are looking for a vdrop mod . I`m not shure how it will work since the power to the cpu is supplied by the adapter . By the way ,don`t try soldering the mobo if you haven`t done that before ?

no, you don't need to do that. It's just a setting somewhere. remember past 220 fsb you need to up pci-e freq to desired fsb/2.2.
Remember all the obvious stuff, trun off spread spectrum, set memory timings a bit loose at first... my P4GD1 was "plug n' play" and runs fine @ 11 x 250, 1:1, 2-3-2-5 @ 3.2v 24/7 at 115 pci-e freq.

Have you found any vdimm mod for the board? Except the 3.3v rail mod?

I have done it before and I do not know what went wrong, droopmod worked but had 2 get it off and soldered it up again and didn't work anymore and vcore 0.2 lower

If it worked first time get rid off all vmod stuff and do it again from scratch. Anyway the clock in your signature is very good , from what i have seen i don`t think more vcore will help you , at least not on air .

Got Spread Spectrum Disabled and tried to loosen the mem timings ... and nothing
:rolleyes:

upping vcore and chipset voltage didnt help.. ive tried tccd and "new" BH-5. Different multis and higher pci-e frequency.. nuthing helps :( I have started to think there is something wrong with my mobos chipset, like it couldnt handle fsb past 151.

I gotta send my processor to my friend and he tests it on his P4P800.

And i have water running in my cooling system.. cpu temperature around 32-40.

If vcore can get higher I can do higher FSB with lower multi and I will put it on water :) But I will try again tomorrow or smthing, so little time these days :mad:

Mine it's a Philipine too but month 04, i can do 216x12 (2592) at 1.6vcore :( but it's rock solid stable :)
I can do 222x12 (2664) and run SuperPI 32M but it's not stable on other programs :(

I've tested my 750 last night : 9h flawless Prime95 @ 2550Mhz /stock vcore screens when i go home :D

Hi JeanY ;)

Nice mod on the waterblock :D . It does not look like a CPU waterblock .Is it a chipset waterblock ? How much fsb are you getting with this chip ?

It's an cpu Wb created by Rosco and DerfOne from cooling-masters for now i'm hiting a wall at 190 in 1:1 because my P4P800 Vm just deliver 2.65V for my Bh5 . Tonight i will v modd it :D

Looks very small for a cpu waterblock , i`m still loking for one that fits .

BTW,i prefer an OCZ booster instead of vdimm mod

If you look at the very first summary post, there are some who have had a bad experience with OCZ Booster and P4P800-VM

Update:

Still on air. Had to switch to a divider because of my ram.

I think it has more in it too! :toast:

Seems that these mobiles are all equal , it does not matter if you have a 770 or 730 it will hit the roof between 2500~2800 on air .

Anyway , really nice result . :toast:

Thanks,

The craziest thing is the temps. Between idle and load I'm only getting about 6 degree difference. :eek: On water that is normal but on air the temps usually jump a bit higher.

I just got my second 730. Locks up at the exact spot my last one did. And the guy who bought my last one also locks up there with it. This is seriously looking like some kind of intentional limit on these cpu's. But to test that I need to know how to read week dates, and I'd need a lot of people to post their Dothan's model, stepping, week date, and max prime stable overclock.

Hmmz strange problem, just fixed my vcore. So I put 1.6 on it. Can get
225*12
235*11
235*10
238*9

anyone knows what the hell is going on? ( it's nog my mem, got divider on it ). Or is this just my max? Temps are a bit high so water is going on it tomorrow or tonight, maybe then I will get higher.
