My ATI Radeon 5850 review (Gigabyte 5850OC) (custom dual fan model)

[seanlimys]

good..will try it out later..

how bout sapphire bios? other overclocked bios perhaps?

Hey guys thanks for the tips. I read it from first post to last and it helped me out in everything from did I get the right card to how to fix it up.

I updated the bios to v7 and then used CCC to up the speed. Unfortunately while the new bios is good at downclocking the card in 2d, it doesnt work when I have CCC overdrive on. So what I have done is used the CCC profile http://forums.techpowerup.com/showthread.php?t=117633 to make 2 profile, one for 2d and one for 3d.

In 3d I get 920/1200 stable using furmark @1900x1200 resolution. The temperature peaks at 86 degrees. I used the profile trick as per the instructions in http://forums.techpowerup.com/showthread.php?t=117633 but in 2d it would only go down to 300/1200. I dont know why the memory clock won't reduce.

So I made another profile, called it 2d and switched off the overdrive which gives me 157/300 in the desktop.

Does f7 fix the 55% fan speed bug?

happy to hear that, in fact the new bios did improve a lot. the only problem now is the heat generated which is opposed to what Gigabyte's has advertised. i believe even the reference card wouldnt generate that much of heat

Do you mean 45%? In the desktop thats is what it is running at with no overclocking on. In CCC I can manually decrease the fan speed to 20% but I have opted not to in case I accidentally start a game in my 2D profile.

@sean -- will try to OC when I return home next week; I'm currently on travel jsut using my laptop

@ dark -- nice fix! might try that as well

@TT -- in F7, my fan now goes down to 44% from 55%

I also re-installed 10.6 after using DriverSweeper. This fixed my 2D problem....except that now CCC won't start! Don't know why. Will investigate further when I go home

There never really was an 'Issue'

The fans minimum speed in RPM reported by windows is ~2500RPM what this doesn't take into account is the dual fans, in actual fact each fan is running at 1250RPM and monitoring apps read it as one big number instead of two.

 

[seanlimys]

i still doubt the performance of the dual fan..

Hello,
it's here while watching how badly gigabyte done work on the new bios, it did fix speed control if I'm correct, I have also tried where possible but this really bothers me, I have a card ITX chassis on the table and the fan noise of 45% -55% Is really annoying, who has a box under the table so it's about the mind, has anyone else had any ideas what to do with control? manually by means of an additional controller, I really want to drive :-(

 

[seanlimys]

i set mine to 95% at ccc for safety reason when overclocking

 

[opinena]

Hello all,
so I did not stand the noise it today and added manual control Zalman FanMate 2, which decorates the back of my box, it is done hastily, went all aesthetics aside, if I download speeds to a minimum, the card and I do not know at work and surfing the holds 35-38 Celsius, tests and benchmark in the game still do but now I'm satisfied, I documented and you can look in the gallery at the very end.

I wish a lot of patience with this not-so-hilarious card (BIOS)

everything in the gallery, at the end

hi opinena, your card is running cool as i can see. mine is the other way round. wonder if it is the card's problem or the bios

Well I think the problem is mainly in the BIOS and go to the manufacturers to do something about it, the card I picked up due to power,after three and two BIOSes gigabyte asus problem persists with the impossibility of automatic speed control, it makes me upset 2 weeks now I was really happy when it comes to buying a new card number to be so HD6XXX gigabyte sample probably will not.

 

[seanlimys]

since so many bios you have tried, most likely it should be a mass faulty card around the world. haha

Well, I sent a mail to gigabyte a couple of months ago and they said they where working on a fix to make the idle fan speed lower. Is minimum fan speed still ~1250x2?

Yer, it's the same with any dual fan card, both fans are connected to one connector on the GPU so windows can't tell that there is two, it's quite common apparently.

 

[TT88]

I don't see how windows or any OS has anything to do with this, isn't idle fan speed controlled by gpu bios?

 

[SilverSilence]

Yes it is, I'm not arguing that. But the fact is you use Windows to monitor the RPM of the fan, and windows can only read one signal from the GPU, so it combines the two fan speeds and that's what you see. Is it really that hard to understand?

 

[seanlimys]

hope gigabyte sees this problem

I was referring to the ~1250x2rpm bug so why are you answering with that windows shit?
I never asked why windows don't separate the two fans. I just want the fans to run at a reasonable speed idle, and I'm on vecation now so I can't test the new bios until august.

@seanlimys - They do know the fans are too loud idle, I just hope they care to do anything about it.

 

[seanlimys]

well, i would say that this is just a graphic card, unlike some toyota cars that you can recall if there is any problem though

 

[SilverSilence]

lolwut, 1250rpm idle is low, lower then the reference model fans...

 

[OnBoard]

Accelero with 3 fans reported fan speed just fine. If it says 2500rpm both fans do that. Now if it's wired funny, as is both fans get a yellow RPM wire, then cut one and see what you get

 

[TT88]

I don't care what software says about my rpm speed, I just want the damn graphics card to be silent when I'm sleeping or watching a movie
My gpu idles at about 32C so there should not be a problem to lower them Arrrpms with a new bios release.

 

[TT88]

I've never heard a reference 5850 card but some people says this gigabyte card is noisier idle.
If you see post 183 you see that idle rpm is actually higher than during full load, which I think is ridiculous.
