My M9 runs at 220MHZ core and 400MHZ memory. On my Desktop my Radeon 9000 CAME WITH IT set at 250MHZ core and 400MHZ memory. So my question is do you think it would be safe to overclock my M9 to run at 250MHZ core instead of 220MHZ core. I know it wouuld make a very small increase but do you think this would be safe?
What I have found from tooling aroround with all 4 cards is that when you reach the max of the card you will see artifacts and you will either be able to change the settings back yourself or the card will reset itself back to the defaults. I have not been able to "overheat" a card.. Let it be known that I start at 10mhz over core/memory and when I get artifacts more back 5mhz at a time. I would not suggest just putting the settings up 25mhz and playing a game. I used aquamark benchmark software and after a new setting I would let aquamark run and If there was an artifact, choppyness, or freeze I would simply exit, back the speed down a little and try again. I am not seriously looking at mounting a heatsink on this little thing and getting at least the stock clocks of 300/600 out of it.
The core speed indicated by the manufacturers can indeed be obtained with proper cooling. But be carefull about the memory!!!
It's not that a desktop or review card runs at 300/600 that all card will. Some manufacturers equip the cards with slower & cheaper memory. As the 5200 for instance runs at much lower memory clock speeds it would be foolish of dell to put 600 Mhz capable ram on it. So i very much doubt you will ever get anywhere near 500 let alone 600 Mhz.
LEave the cor at standard and increase only memory, once you see articfacts, you went too far in the memory overclock.
Luckely dell uses good memory on its cards (thats why Higney85 managed to get allready up to 470 Mhz from 382 (which is allready a good overclock)). My nvidia 5650 memory easily overclocksfrom 570 Mhz to 675 Mhz. Any higher causes instability and performance loses though.
I have completed 3DMark2001SE and 3DMark2003 with my FX5200 64MB at 245/525. I got 8025 in 3DMark2001SE and 1608 in 3DMark2003. This is up from 6788 and 1226. I cant play a game for more than 15 mins at these settings however. I can play games like lord of the rings return of the king for hours at 215/500. I should note I acheieved the 3DMark scores with no mods to my card at all however I have modded my card since which may be responsible for the hours of gaming.
My Mod: I noticed when removing the video card that one of the BGA memory chips had contact to the chipset heatsink below the video card. This heatsink has a connection to the fan area of the laptop. The weird thing was that only one of the 2 memory chips had this cooling. I decided to buy 2, 3 packs of thermal pads at compusa for a couple bucks each. I cut them into quarters giving me 24 little pads. I stacked them ontop of eachother until the makeshift pad was tall enough to rach between one of the BGA chips and the lower heatsink. This may be helping to cool my memory. Its a quick mod that may or may not have any effect.
I wanted to replace the pad on the core you were talking about with a copper sheet like the 8500 users had done but i was too nervious to take the heatsink of my video card and i didnt have a source for a flat shett of copper. I think some arctic silver 5 compound and a copper plate would vastly increase the core speeds us 5150 users can reach.
