Is this normal?

Does your monitor use a lower Hz rating at lower resolutions, and can you lock the Hz to 60 on the monitor. If you can try it and see if the problem goes away. Failing that borrow a monitor and there cables and see if the problem vanishes.

The only artefacting i've seen on boot is random, Never a full solid block like that. Added to that boot artefacts often have areas of solid and dotted colours. You would expect to see the same effect in game as well. The other main type of artefacting is tearing triangles from a single point. Again you do not seem to have this problem.

Hmm you may be on to something here. I mean my monitor is not that high end. 60-65 hz and a 5ms delay make me think that the monitor isn't keeping up, not the video card. Thx for the ideea, now i have to look for a new monitor too

edit: Checked and it does the line thing just wen it changes resolution adding the slow speed of the monitor i tend to go in favor of the monitor as being the problem. Well not a problem just that you see what your not supposed to, or something like that, not sure tho.

8800 GT doesnt do it so it's the card not the moniter.

Can you give your system specs ?

And for me is not happening all the time. At list wen system shuts down correctly and reboots correctly the lines may appear 5-10% of the time, but wen i recover from a not normal shut down (like in your case) they are pretty there all the time in fact i'll give 99% of the time.

And i still have no idea if it is a bad sine or just a bad monitor refresh rate thing.

I've been getting the same thing with my Sapphire HD6870 every time the screen res changes during booting (BIOS to bootscreen, bootscreen to desktop). If you're not getting any artifacts in 3D mode (under heavy load) I wouldn't worry too much about it.

You could probably provoke it manually by changing resolutions, allthough that might not work if the driver is loaded (= windows all booted up)

the 8800 could use a slower resolution switching method. The monitor would be able to catch up before the lines were displayed.

The reason i picked the monitor been at fault is i used to have an older LCD that used to do something similar when paired with a faster card. The card was pushing the monitor at a rate the monitor couldn't handle before the drivers of windows kicked in. Once widows is up the drivers keep everything under Vsync and the problem disappears.

The easiest way to replicate it in windows would be to turn off Vsync, run a game at 640x480, then alt tab to desktop a few times. You should be able to replicate the problem.

It looks like it happens when the display get enabled/disabled or when the resolution changes. Do you have another display because it could be the monitor trying to change display modes, not the GPU if you're not noticing artifacts during normal operation. Also do you have another GPU to confirm that it is the video card and have you experienced any stability issues since this started?

Who ever said that the GPU is faulty off the bat needs to learn how to troubleshoot issues before sending stuff back right away.

Edit: I do recall slow resolution switching with my 8600 GTS.

[95Viper]

My HD6950 has done it since day one.
And, it plays games fine. Have had no other lines, except during the start-up of Windows.
Like, Iceni stated, I, too, believe, it is the switch in resolution from the Windows boot resolution to your chosen resolution of your os.

If, I recall correctly, I use to get this in the old DOS days using that DOS GUI, whatever that was called.

Edit:

IMO, I believe it does have to do with the resolution change during boot and the drivers loading and switching to the resolution of your choice.
Since, it is hardware dependent, some may see it and some may not.

Quotes from Engineering the Windows 7 Boot Animation:

We started with the Win7 boot loader using a different mechanism to display the boot animation. It gets a pointer to the frame buffer from the firmware (either BIOS or UEFI firmware), and displays a higher resolution image (1024 x 768). It animates the image while the kernel and boot critical device drivers are loaded into memory. Since the native graphics driver for the display is not loaded into memory and initialized yet, the animation is run by using the CPU, and by updating the frame buffer for the graphics display. We made an additional optimization - to have the CPU use write-combined caching to accelerate performance.

Designing for a wide range of hardware


The boot experience varies depending on the user’s hardware. We made some design decisions to ensure the best visual experience across a wide range of hardware, however the time it takes a system to get to the desktop is mainly hardware-dependent.

For example, you may notice that there is a delay before the animation starts during boot, and this delay time varies depending on system hardware. To optimize for showing immediate feedback, we actually display text on the boot screen before Windows has had a chance to start all the processors on the system. It is only when that is complete that the animation can run asynchronously to the rest of the I/O during boot (which as discussed earlier is necessary for optimal performance and quality).

You may also notice that the Windows flag’s dimensions during boot may change slightly on different screen sizes. Due to technical constraints in Win7, boot is always displayed in our recommended minimum resolution – 1024x768, regardless of the system’s native resolution. Today, most hardware is set to stretch the boot sequence to fill the screen, as opposed to centering it. Consequently, the boot animation is usually stretched on screens that are of different aspect ratio than 1024x768; however, we did test the sequence on common aspect ratios to ensure that visual quality was preserved.

I tried on my 2nd system with a GTS 465 and got the same flash of a bar of white at the top of the screen, just before going to the Windows 7 desktop.

i had a 560 ti and it didnt do it.

[baggpipes]

^^ I agree... It doesn't look like artifacting to me... It looks like a refresh rate thing... New catalyst drivers maybe got installed when you put your SSD in??

[Steevo]

Mine does it (5870) and has done it since it was new, it is caused by the GDDR5 and core changing speeds, and or a frame drawn that is changed before it gets fully rendered.

Most manufacturers offer 3 years warranty. RMA if in doubt.

Also what erocker said is correct. Hardware faults will cause artefacts, in boot, whilst watching dvds or and in games and cause instability. Really in any situation where the GPU is working.

If its just in boot, but you don't see artefacts in games and multimedia it might be at a driver level or a bios issue or another external issue. But a 5770 outperforming a 5870 does indicate major performance loss.

CF 5770's only within 10% of 5870
Not to many 5870,s keep up.

Soon gone for 4gig 680.

Later
My 5770's

You know, it might not be the video card, but rather the display. Has this been reproduced on multiple displays?

Beat me to it. Both of my HD4870s did it in single and crossfire modes, and both of my HD6850s do it in single and crossfire mode. If you overclock your card, it'll do that on clock change as well.
As far as I can tell from the video and what you've said in this thread, there is nothing wrong with your card.

"Not many 5870s can keep up??"

Antandtech tells a completely different story. The 5870 keeps up with the 5770CF just fine. They seem somewhat on par.

My comment is correct, the 5770 CF is within 10% above or below the 5870 depending on the task.

Usually below if decent cards.
Had an OC,ed OC ASUS 5870 in another another rig and was slower in benchmarks.

No biggie as both good cards and does take two 57's to compete.
Plus CF problems if any, And only one game I play it affects< MS Flight.

A line that huge isn't an artifact. As long as it runs fine and doesn't do it in game, I don't see a problem with it. Like others have said, could just be a weird mixture of your motherboard/ram/bios/monitor..etc

[Derek12]

Its the monitor changing resolutions

[radusorin]

Right now i'm stating to think this is not a problem of any of theme. It's just some soured of a lag, if you like, that appear when the graphic card changes resolution. A sort of delay in the chip or something on that line, that is making the monitor go in sleep mode (as if no signal) and then (after the res change, probably in under 1 sec or so) the signal comes back and the monitor gives those white line as a result of the mix .... Or at list something around this lines. And let me say it clear ... this dose not mean that your card is broken, if you don't have any other problems, artifacts or suspicious behavior. That is just my opinion on the mater.

[D4S4]

my x1800gto flashes white and red lines while booting and while ati tray tools are loading up (idk what is exactly going on when att load, i suspect it's some very low level mode switching), it's been doing this since i first installed it in 2006. while overclocked 40% and it's not dead yet so i think your card will be just fine.

that artifact line is a bit suspicious though, does it happen when your card switches to higher clocks? the only logical explanation i have for that is that clocks are set a little bit before the voltage kicks in therefore causing a little bit of artifacting.

Btw i did found the problem ... i'm running 1680x1050 and his res is 1280x800

Isn't a major factor really, because the performance gap and disparity between the 5770 and 5870 is so wide and vast that even running at a higher resolution of 1680x10650 the performance difference should still be leaps and bounds ahead of a single 5770.

1680x1050 isnt even considered high resolution these days anyways.

Edit:

If you look at the image below. You'll see the even at a lower resolution (1280x1024) the 5770 is still 29% slower than the 5870 at a higher resolution (1680x1050)






Edit 2: Important:

PS. I used the 5850 as I couldn't find the 5870 on the graph - but they both perform similarly.

However, in the case of Battlefield 3, it's an exception to the rule. Judging from the image below that particular game doesn't show the performance gap as wide as others.
At 1280x1024 the 5770 gets 31.2FPS and the 5850 gets 35.7FP at 1680x1050. Very similar frame rates which which mirrors yours and your mates experience. Which brings me to the conclusion that BF3 just isnt optimised well enough to show the true performance gap between the two cards in question like the other charts/reviews show.

If you look at the image below. You'll see the even at a lower resolution (1280x768) the 5770 is still ALOT slower than the 5850 at a higher resolution (1680x1050) - Your card isnt performing right!

http://oi40.tinypic.com/sgigyh.jpg

Neither is my hole system but wen i turn every detail on/max it out, only in bf3 is not up to the job ... i will try this card whit the new ivy bridge system and it shod give me a little more. But on ultra + 1680x1050 just not sufficient video memory, even on high there is a little lag here or there or better said sufficient to make me quit rage and almost throw something at the monitor . But for now no maximus 5 formula no 3770k and still not sure witch video card to get 7970 or 680 .

But yes the card is a beast and it does everything i want, the problem if I can call it that, is the game (y u need so much video memory)

[Vendor]

i have the same card and same issue and actually i don't think it's an issue becoz this is one of my newly bough card and works fucking perfectly and i installed in gentally too, no overclocking done just some fan speed adjustments in MSI Afterburner, i don't think it's a issue.

[sykozis]

My HD4850, GTX275, GTX460, GTX560Ti and HD7870....all experience this same anomalie. I doubt that the card is faulty....otherwise, my last 5 cards have all been faulty.

[craigo]

your card is obviously irrepairable and broken
you should immediatley remove it from your system carefully package it and send it to Australia
the only hope for it to ever operate correctly again is as the third card for a tri-fire setup... remove the card and send it to me asap!

previous replies have recomended everythin i was going to and more
