*** Official Radeon HD5800 Series Overclocking Thread ***

[flopper]

Got my 5850.
His brand.
run 3d vantage at 850/900 15k.
cpu i7 4cores at 3.3ghz.

still need a updated bios (asus) for flashing the card.
using msi afterburner/amd gpu tool.

as far a nice upgrade.
Company of heroes.
1920x1200 dx10 all maxed even model detail 0xAA.
5850 725/900
58 min fps.
115 average fps
231 max fps.

4870 512mb 790/900 before same settings.
1920x1200 max all model detail 0xAA
37 min fps
78 average fps
149 max fps

The difference at 8XAA was around 50/40/50 more fps to the 5850 advantage.
At 0xAA overclocked 850 on core added the following increases fps (58 to 71 min fps) (115 to 127fps average) 231 to 254 max fps)
Same in everything else, a 125mhz increase.

Pleased

That min fps got a huge bump. To much increase for only 125 MHz that cant be right. If i'm not mistaking COH had the same engine as DOW II. I use DOW II for benshes i have seen the fps variate a lot. What i do is do 3-5 runs and add all min fps numbers and divide it by the number of runs. + if i see that the min fps is lower then normal i will redo that run.

yea, it will vary, not doing science here.
same conditions apply, same hardware, same settings, one run.
Wasnt interested in nitpicking exactly as this I just do for fun.
Dont like to benchmark

Really nice HD5850 OC Flopper!

This is a card to buy if you want to save over $100! I must admit that I'm not even OCing my HD5870 for gaming at 1920x1200! I only oced my card for fun and few quick benches!
The only game which might need OC is Crysis, but I will play it again after finishing Heroes of Might and Magic V I'm playing now ...
