I would have loved to see how far it can go without voltage modifications.

Official for Sapphire cards only. ;) Officialy it supports two 5000 series cards only, 5850 Extreme & 5830 Extreme. But I think it can be used with other cards too.

Nice OverClocking...

is the TriXX official tool to overclock?also does it support HD5XXX cards?

Thanks ;-)

Get TriXX and all the infos related to it from the official website ;-)

HD6850 Pushed to 1Ghz !!!!!!!!

Testbed :

AMD Athlon II X4 @ 3.6 Ghz + CM Hyper 212
Transcend DDr2 2x 2GB @ 860 Mhz
HD6850 GPU ( pic on the first post )
GA-MA78GM-US2H motherboard
Corsair GS600 PSU + CM Elite 430
Windows 7 - 64 bit SP1
Sapphire TriXX OC Utility V4.0.2
AMD Catalyst 11.10

GPU Core Speed : 1000 Mhz
Memory Speed : 1150 Mhz ( 4600 Mhz effective )

Vcore : 1.266

*i40.tinypic.com/351wkdl.jpg

Details :

Initially I pumped 1.250v to reach 1 Ghz - I was able to finish 3DMak Vantage, 3DMark11, Uniengine Heaven ( all maxed out ) ,Metro 2033 ( all maxed out ), benchmarks but all of those were symthetic benches - when it comes to real world I played L4D2, CoD Black Ops and these two were stable but BFBC2 and BFBC2 was not stable - so I pumped 1.258v - even after that BFBC2 and BFBC3 was not stable - when I set the core volt to 1.266 - BFBC2 , Crysis 2 ( with DX11 and High Res pack ), BFBC3 @ all maxed out ( tested 1 hour each ) including every other games ran just fine.

For the memory I have set it to 1200 Mhz and 1175 Mhz but they were not stable - found out that 1150 Mhz to be stable enough.

Now some real world temp measurements - benchmark apps just can't push the gp usage to 100% so the temp they are showing can't represent real time gaming very well - so measured temps with with BCBC 2 and 3 which can push the cpu and gpu to their maximum limit ;-)

Temp readings :

BFBC2 @ 975/1125 MHz (1.218 V)

*i39.tinypic.com/8vydfd.jpg

BFBC2 @ 1000/1150 MHz (1.266 V)

*i42.tinypic.com/2mxfrz9.jpg

BFBC3 @ @ 1000/1150 MHz (1.266 V)

*i42.tinypic.com/dq6g7t.jpg

Reaching 1Ghz was my goal when I first stared OCing the gpu and now it's time to find out how much I can push the gpu core with stock volt for normal usage ;-)

Temps are cool too. :shock:

Great results topgear. Can you post a screenshot of the Fan Control tab of TRIXX?

One thing i did't understand the difference in readings of GPUZ is that due to the version

awesome overclock topgear

@ all - thanks guys for the comments.

The gpu is cooled down by the stock cooler and the Hyper 212 is taking care of the cpu ;-)

Here's the pic of fan control tab ;-)
