Tpower i45 P45 revA2 vs P45 revA3 FSB OC report

[PcCI2iminal]

The visual difference between the Tpower P45 rev A2 and rev A3 is minimum ,the old rev came with bios ROM 0620 and the new with 0710 but i am not sure if it is a valid proof to recognize rev A3
will be necessary to remove the heatsink to check (or use cpuz ^^)

Biostar Tpower i45 5.1
AC82P45 - SLB7Z rev A2





Biostar Tpower i45 5.1
AC82P45 - SLB8C rev A3




and about OC?well,A3 should be better than A2.. Intel can not possibly revise a product and make it worse ^^

Biostar Tpower i45 flying on air,this board is the legend and at mainstream price 2 ^^

No worries about overclockability as bios optimization has been able to yield OC of more than 660fsb for both but the new revision seems to be better than A2 ^^.

Will be keeping an eye on this as my next project will be a modded BIOS for the TPower by the looks of things can you make the pics smaller tho please It makes your post pretty hard to read

too bad they are still not raid enabled boards....
thats the one and only reason i never bought one.
that and i havent seen its quad clocking power...

Hows crossfire performance now on these babies ? Thx for the comparison PCC2Iminal

next time i will try to resize ..or thumbs maybe

well ,the Biostar is not good as Asus or Gigabyte but its enough for 24/7

good question
actually i have only one HD4870X2 but i think its time for a new one or 2 x hd4870 maybe

I can test stuff like CF performance on the TPower if we get enough donations, 2x 3870s should be enough to let the board stretch its legs.
