Dude, do you really have to????

[John Beaulieu]

need to see what it can do mate - like when you get a new car, you always have to test it out

[PeteBrant]

Try ATI tray tools John, it has a stress test included to give you your max mem/core speeds, and gives one of the more reliable results compared to others. Lots of other toys in there too.

Oh and stop gloating that you have such a mint card ya bastard! lol

My 9800 Pro looks feeble now!

All that Battlefield 2 goodness you must be enjoying "Maxed Out" 8)

Where's the green with envy smilie???

had a play around with ati tools and checked out the overdrive features - can take this upto 594mhz VPU and 615mhz memory ... what temps should i start getting worried about?

checked out my mates HIS x800xt and his temp is running at 34c @504mhz .. mine has now dropped to 45c but its still a bit high compared to his

ps sorry for seeming to boast - just trying to get to grips with this card

[PeteBrant]

You'll start getting artifacts and "snow" before you need to worry about temps. If you see lotsof white dots, throttle the memroy speed back until they stop, then throttle it back a further 5Mhz or so to give a safety barrier. If you get atrifacts, i.e odd triangles ets appearing, throttle back the core speed in the same manner.

[John Beaulieu]

cheers for that - testing times ahead to get the perfect balance

there must be some threads over on overclockers.co.uk about this ?

[AlwaysAce]

well, i managed 590 core and 1280 memory on my his excalibur x850xt pe.

mind you the supreme cooler helps

[John Beaulieu]

David - you can get lost on the overclockers forums .... plus they aren't as friendly

AlwaysAce - only had sapphire x850xt pe's in stock - only HIS were x800 pro's

[VR46]

John, meant to ask, have you got any 3DM05 scores, are they much better ? or ideally exact comparisons (score with old card and with new one)

[John Beaulieu]

got some 3dmark03 scores - old card (9800pro which had been clocked upto 9000xt speeds) was around 5500 - new card (x850xt pe) 11700

3dmark05 on this card is about 5900

[VR46]

thanks, so were talking double the performance 3DM03 wise and 5900 in '05 is certainly no slouch !
