I so confused 256MB DDR2 800mhz memory and 600mhz core

[hecthork]

Rivatuner actually displays 800MHz in the chart in Hardware monitoring? Not 400MHz, but 800MHz? If that's so, I'm very surprised to see even Rivatuner gives false info. Either RT and GPU-Z are reading the memory wrong or your card would have GDDR3 instead of DDR2, but it is absolutely certain DDR2 cannot do 800MHz (DDR-1600).

Can you read what it says on one of the memory chips and post it?

i will check the chips of the video card of my brother.

i agree with you n_n ... but its fast ? and play HD movies of blueray disc -.-! and i cant in my mobo 946gzis with 8600gt 1gb (2x512 MB ddr2) i will change my mobo u_u the mobo of my brother is PC CHIP -.-! all about this is crazy... like in the title... " i so confused... "

Changing the motherboard will not improve performance, it would seem the bottleneck for playing 1080p resides in your CPU and ram. Your brothers rig only has 1 GBs of ram and your rig has a slow single core Celeron D. If any upgrades are performed I'd attempt to upgrade to a minimum of 2 GBs total in your brothers computer, I seriously can not see a Celeron D handling 1080p well. Most people that use their rigs for movies (HTPC) tend to have energy efficient dual cores.


I do not want to blame your old hardware, but you've tried everything, what else could it be?

Edit:

I can remember my old heavily overclocked ATI x1600 Pro, and current Athlon X2 3800+ @ 2.7 GHz with 8 GBs of ram used to struggle with 1080p, the video used to be slightly jerky.
