those mobos are stock. no vmod at all

lets some pictures of mobos

1ST, P5WDH... BOOT UP AT FSB434.
E6600 1.57v
800 2GBHZ 2.4v
0088 bios
MCH 1.6v
FSB 1.2v









2nd, DQ6... MAX BOOT UP AT FSB400~409.
E6600 1.57v
800 2GBHZ 2.35v
F2 bios
MCH 1.2v (NORMAL)
FSB 1v (NORMAL)








using giga's software to reach 434, it will not boot from bios with FSB over 405 (in my case, i did 416 boot up once but it is not easy, only 400 is ok)





*****UPDATE*****
with V-MCH +0.2v, now i can boot up at FSB 433.... however, once turn off the power it will not boot up again!!
the result with FSB 433 and 1:1 same as P5WDH 3-4-3.
32M is MUCH slower!








still testing 304 mobo


P5WDG
pro:
1. High FSB boot up! no one is going to use soft FSB set everyday!
2. easy recovery if fail to post, 2nd post will use default setting and previous bios options saved
3. CF
con:
1. High FSB over 350 can't use DDR2 1000+ option. some ram's hidding timing are not currect and result is fail to post
2. 975 MCH requires higher voltage

DQ6
pro:
1. a lot of bios options and fsb up to 600, vcore, vdimm
2. MCH for 965 is better than 975, with normal 1.2v i can boot up to 400
con:
1. memory divider has same problem with 975, with high FSB can use DDR2 1000+ option... some hideing timing is not currect
2. too many bios options are NOT working, like say 1.6v+ vcore just won't boot!!!!!!
3. very bad bad bad bios design! you can't change all setting at once, you need to change one option, save, boot up ,change one option, save, boot up again and repeating until everything is done.... this is soooooo gay
4. no program available for soft ram timing adjust
5. not support 7950, CF. nor SLi
6. back plat is not good if you wanna use TQ120!!!!!!
7. too many... not worse to buy one....
