come on MONSTRU lets see some overvolted overclock action on the 5850, its been 14 hours , and we want pics , you know computer guys have no patience,thanks mate

[Oese]

burnmark^^

worst program i ever seen xD > 100°C vrm after 1 min xD

[GLENBOY]

yeh nothing comes close to heating them up like furmark in reality

[Oese]

hate this program xD

[GLENBOY]

its good if you want to bork your cards, i saw a thread somewhere and the guy said i did 20 loops of furmark with card overvolted, then my card died, what he expect, i think its ok as long as you monitor the temps like you did in the above screenshots

[jaredpace]

haha, need a VRM waterblock... lol

[Oese]

2 min.. now thats enuff artificial stability for me xD

vrm waterblock would be nice for furmark indeed xD

for normal games i dont need, in crysis, the vrm's get only up to 75°C

whoever invented this tool wanted piss off the cards manufacturers xD

[GLENBOY]

yeh thats some heat , when i had my 3 x 4890s in it would heat the whole room , no need for cental heating

[Oese]

lolz

[Oese]

crysis original 64bit dx10 very high 1680x1050 4xAA 16xAF MSAAA

never thought i'd get crysis that playable with this card^^

[GLENBOY]

yeh crysis seems to fetch any card to its knees generally

[nascasho]

I want a WHQL approved driver soon...

Little overclock review for a friends blog. Originally in spanish,

I think is time to play with crossfire

[B-Shot]

Does ATIFlash 3.75 work on vista 64? (says OS not supported) Or did i miss a work around?

Great article, and good summary - I like how it compares all the averages. nice work!

[Dami3n]

Thanks . I will make another one about crossfire scalability if i receive my second 5870 in time

Saw the SS' from Oese and decided to see what it was like on mine. I thought his VRM temps were a tad high...




I was wanting to put my MCW-60's on these cards, but after seeing how hot the VRM's get, I think I'll wait for a FC block.

[Oese]

yeah the vrms actually get hot using those passive heatsinks..

thx for posting a comparison )

ahh EK's FC waterblock cools the VRMs properly

[Chickenfeed]

For what it is worth, my 4870x2 vrams would load much much higher (try 100-115C ; that was at stock and gaming, not furmark) than these 5870s ( hell you are at 1Ghz overvolted and still doing under 90C....) Assuming the vrams on these are of the same quality, I don't see what the big deal is.

I'm happy enough with the CCC limits ( yes I know that is crazy talk ) being the default thermals and noise are respectable for me ( compared to my X2 ) Who knows, I might break out my rad again down the road and have some fun though I probably would get it a FC block though ( I know gpu only blocks result in lowest gpu temps but honestly its not like a few C higher on the core for the benefit of the rest of the pcb is going to matter ; only negative is the fact they aren't easily reusable )

[Oese]

the card at the ek test is undervolted to 1.125v and on stock clocks, but whatever, very nice temps

I'm not sure if you can say undervolted, because my card has 1.125V stock as well! This might be only a feature for Sapphire cards or newer batches are already better yelding and they lowered vGPU.

If you want lower power consumption try my BIOS from TPU and see for yourself

EDIT: This also can be a reason why some of the reviews are claiming that HD5870 is louder than HD4870 and others are saying opposite.

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

[Astennu]

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.

thanks for sharing flopper
