Hi there. This is my first post here and I am having a rather perplexing issue. I've just purchased an HD 7970 OC with Boost for inclusion in my new self build. Its been a while since I've put a machine together but everything seems to be going well. The HD 7970 was running ok for the last week but last night it began making a horrid vibrating sound when under heavy load. This sound is noticable whilst playing Tomb Raider. Whilst this was happening I removed the side panel from the chassis, gently touched the cooler mounted to the card and the sound stopped. It seems the cooler has begun vibrating and later today I will be doing some tests to see at which speeds this happens.
The card is only a week old so is this something I should contact the retailer about? Would an RMA be something to consider or is this kind of behaviour to be expected under load? My aim is to build a quiet, cool running system and this vibration is unacceptably loud.
The graphic card should not make such vibrating noises under any load or any game that you play, even during the Stress Test... Kindly check that if the GPU is installed properly, with screws tighten sufficiently.. Other wise contact your retailer and have it replaced!
Thank you for that reply. I was thinking much the same thing particularly as the sound only started yesterday evening. I'm at work now for the next few hours but once I'm back near the machine I will try removing the card and reseating it then ramping up through the fan speeds using CCC. It's looking likely the card will have to go back at this rate.
That's frustrating to hear about that GPU. I was thinking of buying the same one. Also, I live abroad so it'll have to work right away or I'm f'd.
It is a cracking card don't get me wrong. With AA set to FXAA and all graphics set to their highest, high or ultra settings, I can run Tomb Raider in 1080p at an average of 56 fps. Heaven benchmark averages around 25 or 26 fps if I remember correctly. I am generally very pleased with the card particularly as I got it for £230 on an offer from Ebuyer. I was even planning on adding a second one. It's just this vibrating that is the issue. I'll report more fully once I get a chance to test it methodically.
7970 is an excellent card. So do not underestimate the performance of this card.
The little problem that showed up in manfacturer's or the suppliers fault, maybe the card is not installed properly, ca occur in any card..
Also, if you find the solution to your problem, please mark it as the best solution so others could benefit from it.
Absolutely guys. There is nothing more frustrating for someone suffering an issue than reading through loads of unresolved threads that go dead. I'm about to head home so I will remove and reseat the card before methodically testing the fan speeds to check any vibrations. I'll report back once I have more.
Right so I'm home and have just taken the side off the PC and run the GPU fans all the way up to 100%. So far they aren't making the same noise so next I'm going to run Heaven on loop for a while and if that doesn't do it I'll throw Tomb Raider at it again.
Is it possible for an issue like this to be intermittent? Could it result from a combination of the GPU and chassis fans? I was expecting to be able to repeat the effect. Curiouser and curiouser.
The sound can be produced by either of the fans, but if the fans were faulty, the noise should be persistent.
Heat up your gpu by running these stress test, see if the sound is again produced.. If it does, claim your warrenty!
Ok so after some more testing I'm even more bemused. The vibration only seems to happen when I'm playing Tomb Raider and only when the side is on the case. Using TRIXX and Asus Fan X-pert 2 to ramp case fans and GPU fans to 100% fails to replicate the sound.
Yes the temps seem fine. Around 70c max when either benching or playing TR. At idle it works fine, no complaints and during non intensive tasks it's fine.
I've just reset the GPU overclock back to the BIOS 2 stock settings (1000/1450 MHz) and put the side back on the case. So far it seems to be ok and isn't vibrating at all. I'm wondering if perhaps a certain combination of case, CPU and GPU fan speeds may be resonating at just the wrong frequency to create a vibration? Seems bizarre to me but then I'm hardly experienced in these matters.
Thanks guys, I'll post back if anything else develops and if not I'll mark the topic solved.
Well I just played TR and Far Cry 3 without incident. It seems it was down to the overclocking. Temperature related I guess. I don't feel this is solved but it'll have to do until I work out the exact cause.
It was set to 1175MHz core, 1500Mhz memory, VDDC 1237 and Board Power Li set to 20. Anything higher would cause TR to bomb and Heaven would lock up. The temps seemed fine at a fairly constant 70C. My thinking is that as the load increased the chassis and CPU fans ramped up and eventually it hit a frequency that caused the Dual-X cooler on the GFX to vibrate enough to become noticeable outside the case.
To be honest I wasn't monitoring the fan speed during TR. I'm now wondering if perhaps the issue was due to me not creating a fan profile for the overclock and keeping it set to auto. It's possible the vibration I experienced was from the GPU fans repeatedly ramping up and down. I'll get around to testing this properly but for now I'm happy running the OC BIOS 2 that comes as stock. The performance increase for a stable OC was only a couple of FPS at best so it hardly seems worth it.
Reckon I'll just add another one and chainfire the bad boys
