HD 6950 sounds like a jet engine on startup, why?

[dom99]

Hi all

I am Using Trixx version 3.0.6 (the latest one) to overclock my hd 6950 to 880/1375MHz@1.1V. I do not have stability problems at this speed when using a custom fan profile in Trixx and am happy with it.

HOWEVER, when I boot my computer with trixx set to come on at startup, my card just goes straight to a constant 50% fan and will not change unless I unselect custom profile and reselect it.

Is this a common problem because my setup would be perfect without this! My gf gets really eggy when she starts the computer to do a bit of facebook stalking and gets blown over the other side of the room!

Just so you know I have tried uninstalling and reinstalling drivers, using driver sweeper and without.

Any help would be appreciated, this forum is brilliant and I trust that the good people of TPU will know what to do lol

Thanks

I had this issue when using trixx on my 6870's although it would hit 100%, i assumed it was a bug relative to the manual fan control as it was set to 100 before i selected a custom profile but never really looked far in to it as my computer is on 24/7 so it was rare to restart and crap my pants due to the sudden deafening noise

I'm pretty sure it's trixx that is causing the issue but how or why i have no clue and i now have an xfx 6970 so can't really play around with trixx as far as i know

Have you tried something else to overclock like afterburner?

I don't know exactly the issue or reason, but over the years I have had cards from both ATI and nvidia start at 100% fan before slowing down.

I fixed it by going under water!

I think the issue is not the fan speeding up for a moment then slowing down during post, it's that when getting in to windows it hits 50% and stays there until it's changed.

All my cards within recent years have had fans that start fast during post then slow down but its only when using sapphire trixx on AMD 6 series cards have i had the fan get very fast (100% for me, which happened to be what the manual fan control was set to even though i had selected a custom profile an not manual control) during windows start up and only slow down if i either opened trixx or opened then adjusted the fan speed.

That is why i think it's to do with trixx but how or why i have no idea, all i can suggest is defaulting everything on trixx then using something like afterburner or any other suitable program an see if it still happens.

You've set fanspeed in the software. That is the cause. Driver reads manual setting, you probably set custom profile, but driver reads custom runtime as manual @ 100%. when it happens, disable the fan control, and then re-enable.

Hi

Thanks for the replies. I have done some more experimenting using MSI afterburner and it happens with that aswel exactly the same. So yeh it seems that it is setting it to the manual fan setting in CCC on startup.

Hmm I shall keep trying, see what happens when I disable CCC in MSCONFIG on startup, trying to find a solution where I dont have to change the fan setting every morning

 

[micropage7]

or the fins is not steady so it would be pretty noisy before it reach ideal spin. just check it again

My 6950 does this too....Until Windows loads the driver for it the fan stays revved up

 

[HalfAHertz]

Well most modern cards rev the fans at 100% at boot for a few seconds supposedly to blow out the dust...

 

[dom99]

I have tried disabling CCC at startup and seems to fix it, so ill leave it like this for now, thanks for the input

that clearly doesn't work... lol

i couldn't care less about the sound my graphics card makes... i turn fan down to 30 when i'm asleep, and up to 100 whilst i'm awake. I'd much rather have low temps and high fan noise than high temps and low fan noise...

 

[Mussels]

the fans dont run at 100% to blow out dust, its just the fan getting full power before spinning down, since some fans require more voltage to startup, than they do to keep spinning.

its to prevent the fan NOT starting if you got low temps and it tries to start/idle at say, 15% and overheating in no time flat.


as to the problem at hand, clearly some software (be it CCC or afterburner) is having a spaz and locking the wrong fan speed. can you just not use those, and just BIOS mod the fan speed of the card?

 

[Spectrum]

I noticed that using 2 overclocking programs can fuck things like fan speeds up. just stick to 1.

 

[overclocking101]

does it stay revved to 100%?? have you checked temps with gpu-z?

 

[dom99]

When using overlcocking programs to have a custom fan profile the fan will stick at whatever the "fixed rpm" is for that profile in CCC.

Therefore I think this is what is happening. When my computer boots up, the overclocking software doesnt take effect immediatly. CCC takes control first. In CCC when using overclocking software, under the "performance" tab it displays only 2 options which are "power" and "fan control". On fan control the manual tick box is selected, although the slider bar is not changeable and is set at 50%. Hence before the overclocking software takes control it sets the fan at a constant 50% untill you again untick and tick the fan options in the overlcocking software.

This obviously doesnt happen to all 6950 owners or overclockers so must be something not right with my drivers or something. Hmm ill sort it one day im sure, but for now im happy with disabling CCC in MSCONFIG.

I don't know. I've seen this happen before without CCC running every time it has happened.
I almost think its a weird driver issue.
Reason being, I've had it happen on a rare occasion with my 4870x2 in Windows XP, where upon startup it always ran fast and loud until it got into windows and the driver took over, and it would drop back down to quiet slow levels. It always did this and I figured it was some odd hardware thing they built into them, and this was back to driver 10.5

But every once in a while, the fan would stay "stuck" at the louder speed.
This was with CCC disabled, and no other OC software even installed, as I had modded the clocks and fan profile in the BIOS so I wouldn't need any software to do that.
A restart and it was fixed.
Again, only happened a few times over the years.

Since I've had this 6950, (3 months) I've had it happen twice in Windows 7.
As soon as the driver kicked in, it would crank the fan up, and this is without CCC running, and without any OC software running.

The fan kicked in at about 60% (per GPUz) and I checked my setting in the profile.xml file and it was set for 48%, so it didn't pull the setting from that.

Anyway, still have never figured out why it does that on a rare occasion.


Oh, and to answer Mussels question, no the BIOS can't be modded (yet anyway) to adjust any fan profile curves, but I doubt it would fix this odd glitch anyway.

Thanks for the reply

Looks like one of those strange driver issues that can probably only be resolved through a clean install of windows lol. I have noticed in the registry some hd 4800 stuff (my old card) still knocking around which driver sweeper hasnt managed to get, therefore probably a driver installation thing.

You don't have to do a reinstall to remove Ghosts just follow this
1. Type: CMD in start's search box
2. Right click on CMD from the list and Run as Administrator
3. At the dos prompt typed: set devmgr_show_nonpresent_devices=1 (this will show all hidden devices in Device Manager)
4. Type devmgmt.msc (this will take you to Device Manager). Click on View and select show hidden devices
5. Look in Display Adapter and for any grayed out video cards and uninstall them (or any old video card devices). Then check your Monitors
