Overclocking ATI Radeon HD 5870 CrossfireX

[umaymah]

So now, I am the proud owner of an ASUS EAH5770 1GB GDDR5 Voltage Tweak Edition and I'm a fan of overclocking. After testing my new card for a week I told myself it would be nice to know what it was in the belly, so I started to overclock. The first thing I found with ASUS SmartDoctor, the software I use to overclock my card is that my original Vcore is 1.2 v and apparently, when I look at the HD5770 other Internet They all seem to have an original Vcore of 1.125 V. So my question is what heats my card for nothing with his Vcore and frequency of origins.

I think you need to install the CCC since it allows you to enhance the ATI Radeon HD 5770 clock speeds of up to 960/1445 MHz, but with our test sample could not be reached. Everything above the 930 MHz core clock speed and 1330 MHz memory clock resulted in continuous operation at the time to crashes or artifacts. This is 9 or 11 percent more than the standard of 850/1200 MHz. The performance increase in 3DMark Vantage (High Profile, GPU-value) was thus 11 percent (6212 instead of 5609 points).

Take the ATI Tool in order to test the graphics card. I think that the graphics are at fault when it was overclocked too high. I have even a 5770, as already described above, now I just wanted this out of boredom and the fun of it them something. Only to look like the work that way. So I have GPU clock speed and the of 860MHz/1200MHz 865MHz/1225MHz on the screwed up, and tested it (it was the Catalyst Control Center conducted with) but I always said that it had failed.

Now I have all the games over a longer period tested. Problems in my view, only when performance data was changed. Say overclocking. That even if it is only marginal changes. I could see this especially in older games. Other software as far as I can tell that was not affected. Disabling VPU Recover is definitely not recommended. On Windows 7/Vista VPU Recover is integrated into the OS. ATI Overdrive should therefore not be used for problems with games. If I understand it is so, the Radeon cards in the 5xxx operation even overclock. That would make a manual overclocking in most cases totally unnecessary.
