Progress overclocking 955BE / CH4F / HD6870 CrossFire - Page 2

post #11 of 15
I don't think the scores in 3dmark11 matter too much when you can manipulate drivers, especially with the radeons.

600

6850's ^^

With an I7 @ 4.2 , yeah. Your physics score is probably double his.

6870s score around 4.2k GPU score last i checked, he's scoring 7k+ gpu... Could be better.... But, your Phenom 2 isn't doing any favors in modern benchmarks; especially 3DM11 with a Deneb.

8.5k+ gpu (mine):

Default catalyst settings is intended when you're about to compare your score, either at default or overclockd speeds.

In that bench of mine, all settings were at default/application managed. The driver itself had an issue with tessellation settings, and this is well documented, especially in HWBot competitions. This issue has never been completely ironed out AFAIK, and can still be manipulated. This is why all 3dmark11 and Unigine Heaven benchmark scores can be taken with a grain of salt. 3dmark, at least, is flagging those results.

Something wasn't right with this.

The system developed a problem that I have seen before with this same computer.

It directly relates to running the 2 cards in crossfire, see this post for more details.

New stable peak of 4.06GHz (225 x 18)

However I still can't get crossfire reliable so I'm only on one 6870 at the moment (again..)..



edit: turns out it's not 100% stable - hasn't failed Prime after a couple of hours, but didn't wake up from sleep mode properly this morning. Took a couple of forced restarts. Is this a normal problem to come across when OCing these processors?
