The overclocks of our card are 835 MHz core (15% overclock) and 1260 MHz Memory (26% overclock). For your reference, the defaults are 725 / 1000 (GPU-Z is showing the wrong values due to a bug which will be fixed in the next version). As a percentage those overclocks are really nice. The maximum core clock of 835 MHz is clear evidence that this GPU ended on a HD 5850 because it could not handle the HD 5870 clock speeds of 850 MHz. The memory chips are exactly the same as on the HD 5870, which results in roughly the same maximum memory clock. In essence you can get a HD 5850 and overclock it to almost HD 5870 performance levels in just a few minutes. I would also like to point out that you can increase the voltage for better GPU overclocking. The default voltage of 1.09 V is quite low and there is plenty temperature headroom as well. So I ran a quick test at 1.30 V GPU and reached a maximum core clock of 1000 MHz.


5850 & Waterblock
now thats the info we've been waiting for on the 5850 5000mhz rated memory chips and a core with a bit of extra volts thats good for a 1000ish , excellent
