ATI x800pro has low memory speed!!??

celica · Sep 11, 2005, 07:13 AM

how come the ati x800pro memory speed has only 450mhz ,all other brands x800pro memory has 900mhz?

because you're not properly taking into account the fact the memory is DDR so therefore it's 450x2=900 mhz.

each card is different. some overclock well, others don't.

i really don't wanna burn my card if i go to far,cause my traytool didn't show memory temp in the card.

it won't show you the temps. it will continue to automatically overclock your core/mem independantly until it artifacts. Those are minor artifacts, people usually can OC about an extra 5-10Mhz higher than what ATI Traytools says so.

Memory temps wouldn't do you much good. Some system ram prooves this... i.e. Samsung TCCD's can take higher voltages and temperatures than a Winbond chip, so it really depends on what you've got.

You won't fry it if you're care ful and follow commonsense.

the TCCD chips in my system RAM doesn't like to go above 3.0v. between 2.8v-3.0v it works fine.

H3X4D3C1M4L · Sep 11, 2005, 05:55 PM

Sounds about right. Samsung's use 2.7 volts normally for their 250 MHz TCCD's @ 2-2-2-5 running at 200 MHz.

Normal DDR DIMM's are rated at 2.5 - 2.6 volts, so thats considered higher.

lol....i run mine at 2.6v for 2-2-2-5 @ 200Mhz

. @ 250Mhz i run 2.9v
