hello how are u?


since windows 7 support the video card from ram i lost about 950 mb from ram and also my oporating system takes about 500mb i only had about 500 mb left i have 2gb ddr2 @480 mhz ....
and since my mobo takes both ddr2 and ddr3 am thinking about ddr3 but i have question ?
when i sell my 2gb ddr2 ram and buy a 2 x 2gb ddr3 1333 rams
does the video card (95oo gt 1gb ddr2 ) will still be supported by 700mb from the ddr3 ram or not ?
becuase i dont think the ddr3 ram support memory to ddr2 video cards *

* i know it support but will it support memory too ?

Yes, GDDR2 (Graphics DDR) is supported by DDR3 (Memory DDR). Don't worry of this.

so the ddr3 ram will give my video card (ddr2 ) 777mb like it does now ??

Let's back up a bit. Post your system specs, model numbers, vendors, etc... before you go around buying stuff. Your post shows a fairly weak understaning of memory technology and PC hardware in general and I can't think of any motherboard that will run on both DDR2 and DDR3. The 9500 has it's own onboard memory, it should not be using anything from the motherboard.

ok this is my system :-
elite group g41-mr23
e5300 @3.00 ghz
palit nVIdia 9500gt
2gb ddr2

look man am not weak ,, in computers but my video card det. memory is 1gb and the ram support 777 mb that makes them 1777 ! how hard is that ?
and i was wondering if i upgraded my ram to ddr3 will it still give memory (the 777mb) it is giving now ???

Just found this thing, very hard to track down, and a very odd system. If it will run on DDR3, the video card will work just fine with it, as long as the motherboard works with the RAM and the video card works with the motherboard. You are better off not using the system RAM for the video card though. The 9500 is not a very powerful card and the 1gig onboard is more than enough. You will be better off upgrading your RAM to 4 gig rather than replacing it with DDR3 with the same amount.

no its OK i prefer ddr3 rams and its cheap !!!
last question which one will it be better for gaming if i use the system memory to support video card or using it as system memory without supporting the video card ,, because if its better by 10% i'll take that :D

2 gig of DDR3 vs. 2 gig of DDR2 you will see no difference. It's like putting on a blue coat instead of a red one that's the same type. If you want to get more speed, get 4 gig of RAM, either type. You definately want to keep all the RAM for system use.

I'd spend the money you would spend on the DDR3 on a new video card if anything. You can get a $50-70 card that will blow away your 9500. I'm sure others here will agree, keep the DDR2, get a faster video card, or get 4 gig or RAM if you don't play games much.

but man ,, the ddr3 is 1333 mhz and my ddr2 is 400 i guess there is a diffidence no ?

The speed of DDR2 should be 800 vs. 1333 for the DDR3 (400x2 for DDR2, 666x2 for the DDR3), you are comparing 2 different things there. You are comparing the true speed of RAM for the DDR2 to the effective speed of the RAM for DDR3, you need to compare either true speed or effective speed for both. Bellow snipit is from a chipset review like the one you have.

"This entire round-up centres around clock speeds so it's worth spelling out that the numbers we are referring to are a mixture of effective and true clock speeds. The 1,333MHz FSB of the latest Core 2 Duo processors is actually a quad-pumped 333MHz bus so our 2.66GHz CPU runs at 8 x 333MHz. DDR2 and DDR3 are both ‘double data rate' memory so you halve the stated speed to get the true speed, thus 800MHz DDR2 runs at 400MHz and 1,333MHz DDR3 runs at 666MHz."

You will see no difference in your computer. DDR3 has faster clock speeds than DDR2 but a higher latency. While technically the RAM is faster, how you view the PC experience will be the same
