Is that means for the notebook that come with 3450, HP will disable its integrated 3200?
Because as far as I know, both of the models (with or without 3450) still using 256MB sideband (or sideport) sort of dedicated memory which supposed to feed the integrated 3200. Any info sharing would be greatly appreciated.
Desktop AMD 780G/790GX have 128MB of sideport memory, a memory chip soldered beside the NB for dedicated graphics memory. Of course that would not be enough so system memory will be shared too. In fact all computers now do use system memory if graphcis memory is not enough especially cards with 256MB or less or running at high resolution 1920x1200 and above.
In notebook platform, the only model that I know which comes with sideport memory is HP's tablet TX 2500 series. It uses 780G chipset with 64MB sideport soldered for garphics. CQ40 doesnt have sideport memory soldered though(maybe because budget model). So in other words, sideport memory is like dedicated memory for intergrated GPU.

shady, ty for ur info!
that means 3200 and 3450 wont diff so much diff in some mid range game?
is it the more RAM i put in then 3200 (shared memory) wont be so much diff to 3450?
3450 will be smoother of course since it has dedicated graphic memory since the GPU can communicate with memory much faster. Since the max resolution is 1280x800, graphics memory doesnt matter much. 2GB would be more than enough. Another thing, if you have extra cash, I recommend upgrading to DDR2 800 memory since it is faster than the bundled memory and GPU can communicate faster with memory.

Can we feel it if only normal usage and dota (most high-end game played by me

Since i m newbie, so ask a stupid Qs...
If 125ax and 115au using same mainboard, can i add add discrete GPU and make it crossfire in 115au? haha...

basically its the same motherboard. that discrete GPU is soldered into CQ40-125 so you cannot add any GPU to crossfire. Furthermore HP bios would definately prevent any settings. another thing is CQ-133AX(125 replacemet) has internal bluetooth and double the amount of HDD so it is worth it compared to other models. A discrete graphcis would always be better than intergrated but battery life would suffer though.

correct me if i'm wrong....
125AX is using the same mobo as 115AU....and yes 125AX has both graphic card ATI 3200HD and ATI 3450HD....
bcoz ATI 3200HD is built in the mobo ATI 3450HD is just an add on....
u should be able to crossfire it....but HP has disable this feature....

QUOTE(sachinvasudev @ Dec 5 2008, 03:09 AM)
is there any bios update or somethin which we can use to enable crossfire?
HP disabled it for some reason. Not sure why and maybe you can bug them although its probably useless and wasting time.
