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

[hecthork]

well, i so confused with these information

i have two video card,
the first is XFX 7300 LE 256MB DDR2 Onboard (supporting 512MB)

core 600mhz and memory 800mhz
DDR2

its soo faster
how it's possible???

now i buyed a 8600GT Fatal1ty 1GB DDR2 (2x512mb)

core 750mhz

but the memory........... 520mhz??

im not a professional but, the 8600gt. why can't it run over 800mhz???

i have two pc
the first 946gzis Intel
buss speed 133
memory 266.4
1:2

and the other is PC CHIP Bus speed 255 mhz OC (533mhz base) 1:1

before to buy the ultimate video card, i want the 256 gdr3 fatal1ty 8600gt but its only 256mb....but i need use the resolution of 2560x1600, for these rason is necessary more memory.

sorry for my english, im lerning... n_n

Im gonna take a guess here and say probably the 7300 is stating its DDR speed (aka 400 mhz real speed, doubled for 800mhz actual speed) while the 8600 is stating its real speed of 520mhz. Its DDR speed (which is the actual speed it will run at) is in fact 1040 mhz. Its just in the way they state it. Thats what I'm thinking. No way possible a 7300 will be faster at anything than a 8600gt.

FYI the Fatality 8600gt is far from the ultimate video card

It looks like it was overclocked somehow. 800MHz (1600MHz) mem should never be stable on a 7300 LE, lol

its so stable, the artifacts start in 900mhz, but the temperature is over 100ºC

800mhz the temperatura is 73ºC and max 85ºC

what games are you playing, as I understand you having trouble with HD decoding on the 8600GT, did you uninstall the old drivers? did you install the most recent drivers? what are your system specs, procesor, memory, mother board, hardrive, etc...

the games only are reference, i want play FULL (1920x1080) HD movie, but with 500mhz of memo, isnt possible u_u

i have windows 7 x64
the last driver nvidia

 

[mrhuggles]

my old 2900xt 1gb can do 1920x1080 videos no problem with a clock of 200mhz core and 300mhz ram [as low as i can successfully clock it in the bios]

 

[Papahyooie]

post up a screenshot of your gpu-z's

 

[mrhuggles]

mine? dont have videocard in :? and dont wanna put it in and install drivers cuz last time i went from ati to nvidia vista wouldnt boot and i had to reinstall.

but 2900xt its like 8800ultra -.-!

 

[mrhuggles]

want a 2900xt? im looking to trade mine for an acekard2.1[has to be 2.1 or i don't want it] + MicroSD card + shipping on all

oh and fair warning 2900xt has non-default clocks in the bios [would be happy to send original + altered bios]
it runs alot better with the clocks i gave it, both performance wise and stability wise, oh and heat and power usage too

EDIT: oh and also its a 1gb, so the memory clocks even tho i backed off them a bit are higher than the normal 2900xt 512mb

EDIT2: http://www2.dealextreme.com/details.dx/sku.16142 <-- thats what im looking for

I meant the OP, post a screenshot of your gpu-z

these is the computer of my brother, He have the 7300LE now

i have 8600gt fatal1ty 1gb (2x512mb DDR2)

but testing in both mobo, the result is the same.

 

[mrhuggles]

dude if its not playing HD video then i would bet its the cpu and not the gpu
whats the rest of his computer like?

For playing HD it's necessary minimium requeriment in the CPU ?

its my CPU

Windows 7 x64
the last driver x64 nvidia for windows 7

Intel Celeron D 351
3.2 Ghz
Bus Speed 133.2 mhz

mobo Intel 946gzis

memory 2gb

[mrhuggles]

that should be good enough on a good install, maybe you have some software interfering or something

 

[hecthork]

hmmm... i dont now if some software interfering, i checked used (control + alt + del ) all is normal...but its normal that 7300 have 800mhz memo ddr2

and the 8600gt only 500mhz memo ddr2 ????

no not exactly, 400ddr2 and 700 ddr3 so yours is overclocked

 

[newtekie1]

The 7300LE can clock higher because it has less RAM, though I refuse to believe you got it clocked to 800MHz(400MHz real) stable. It just isn't possible for DDR2.

But even if you did, the 7300LE is 64-bit and the 8600GT is 128-bit, so even at the lower clock speeds the 8600GT has more memory bandwidth. The 8600GT shouldn't have a problem with HD Video, there is definitely something else going on.

hmmm.... do you refuse to believe? please explain me to make a review to do for the xfx 7300LE 256 MB DDR2 onboard

 

[mrhuggles]

7300LE = 5.3gb/sec
8600gt = 22.4gb/sec

these are reference the difference is that the 8600gt has a lot more memory interfaces than the 7300LE [more bits if you will]

 

[hecthork]

8600gt = 22.4gb/sec

then, the bus of 8600gt is 800mhz but i have only 400, max with OC is 500 x_x
and my brandwidth is 16.0Gb/sec

and 7300 LE is 12.5 Gb/sec

... how it's possible???

 

[hecthork]

8600gt = 22.4gb/sec

without oc

12.8 Gb/sec
