My Power Color x1300 is a good Overclocking GC .. Yeah ... Luckily i get PowerColor ... Easy to OC .. No Locking also ... using ATI tool
Anyway , if you did not have your card OC from stock core 450MHz to 702MHz and Stock Mem 500MHz to 600MHz , the potential is of this GC not yet purely shown ... of course CM CoolViva Heatsink is needed... Haha ....

If you use Powercolor ...
You can OC the Core to 650MHz with proper cooling and RAM ... ah ... hard to OC ... Can try to reach 900MHz and step by step up the line ...

Ah ... OC x1300 again ....
All GC can OC as long as it is cooled Perfectly

whats the gain ?
Can beat the PRO version lo ....
x1300 with 450MHz core OC to 702MHz can beat X1300PRO to the max
Since PRO only run @ 600MHz with a larger heatsink ....

OC GC Of course not chapalang HeatsinK la ...
Using Cheap CM CoolViVa will do

HAHA ... What Brand you get oh ?
My POWER COLOR can OC till extreme la with good air cool heatsink ... 702MHz
Plan to put water cooling to BUMP it higher

So next time get POWER COLOR
No Locked BIOS or what so ever
One tips .. get those Graphic cards which had small heatsink and change them .... You can get Performance BOOM with low end cards

Oh ... Then GeCube think too much about PROFIT then ... because people will just buy cheap GC from them and OC to get a better rank than normal ...

Haha ... GeCube should be advoid ....

Anyway Locking bios also in an effort to prevent Warranty issues and conflict ... Is a lost for a company if their Product had been Destroy by OC and They can do anything about it

Haha .. anyway .. anyone Try HIS GC before ? can OC or not ?

Ah ... may be we should have a list of GC that can be recomend to OC members
