Good job topgear

[Skud]

Nice clocks, tg.

[d6bmg]

nice review.
rep+.

Nice Review, Topgear.

[Skud]

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

Me too.

nice one TP.

Excellent mate......

[topgear]

Thanks guys for your sweet comments

Me too.

If time permits I'll try to do it

Nice OverClocking...

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

[Skud]

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.

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



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)



BFBC2 @ 1000/1150 MHz (1.266 V)



BFBC3 @ @ 1000/1150 MHz (1.266 V)



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

[S_V]

Congrats mate... Looking forward for more good results.....

[Skud]

Temps are cool too.

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

[mithun_mrg]

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

awesome overclock topgear

[d6bmg]

Temps are very good!! What are you using custom water cooling?

[Skud]

I don't think so.

[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

Excellent OCing topgear.

Thanks buddy.

[vickybat]

Phenomenal overclocking topgear. Bart chips are really very thermally cool. Btw how much fps are you getting at these clocks?

[topgear]

^^ will post game fps difference with stock and Oced clock soon

Excellent OCing topgear.

thanks buddy

Thanks buddy.

you are welcome

[Zangetsu]

@Topgear: can u post the FPS & resolution (Bar Graph) of games u tested on this...
umm..a gaming benchmark

[Tenida]

Nice work Topgear I am also planning to overclock my MSI N560TiGTX TFII/OC to 950Mhz-1000MHZ.

[topgear]

I've not measured any game's FPS yet - only played them for hours for stability testing but if time permits I'll try to do it

[thetechfreak]

@Topgear

I think the GPU is so cool as its Winter now. Atleast its very cold here. Dont you think?

[topgear]

I can't say it's very cold still - when I performed those tests the ambient temp was around ~24c - but from yesterday the climate is getting cooler

[comp@ddict]

Good job buddy! 1GHz is awesome. THe feeling you get when you achieve those clocks, amazing.
