Matrox Do Something! (Flickering Part II)

[ffcia]

Same problem with my G400 16mo SH on a BE6II, C366@550, force agp2x, vio3.6v, monitor philips 105b.
Flickering with 2d & 3d.
I tried many solutions with no succes.
BUT, this is ok on a COMPAQ DESKPRO PIII 500, AGP 1x !!!
I tried on my computer with no OC and agp1x and same problem.
Perhaps a problem with Abit mobo ?
and my resseller told me that there is no problem with Matrox cards.
SO, help us MATROX.

Excuse for my bad french/english
thanks

ffcia,

did the exactly same card work on the Compaq but failed to work on the BE6-II? Was the flickering you mention exactly the same type of flickering we discuss in this thread?

I have a Soyo 6BA+ IV, which uses the same HPT366 UDMA66 controller as on the BE6-II. But to my knowledge people have had this problem also on other boards.

[Haig]

Quick update.

So far, we are unable to reproduce this in house even with the boards that were RMA'd.

We only have 300w PS's and above.

We have tried them on the abit and soyo mobo's mentioned in this thread.


Used SBLive and 33 hd's connected to the 33 ide connectors.

We'll do more testing and see what happens.

Again, if no one wants to wait, the RMA option is still there.

jms - The 32m board draws more current that the 16m boards.

Keep in mind guys, that current draw is NOT the only issue with a power supply. The modern types that we've all grown used to are more directly connected to main power than ever and can have a number of different anomolies that can indeed be unique to a particular layout and component design. This may have nothing to do with the problem, of course, but the way in which two components react to each other, the particular size of a singe capacitor common only to the 16 mb units...anything can be the root cause. Based on Haig's report, it's obviously an incompatibility between components, not the fault of only one. He wouldn't offer an RMA so willingly if they were stonewalling or attempting to ignore the problem.

Information is what they need. Keep sending those configs in, and the bug will be tracked down.

"My" flickering is :
horizontal lines during scrolling in 2D ans opening windows on explorer or other.
Lots of horizontal lines in D3D&OpenGL games. (difficult to explain in english)
This gives a bad quality of the screen (800x600 @ 85hz Philips 105B)
I had a G200 before and i never had this problem.

My config :
Matrox Millennium 16Mo SGRAM
serial : LAA29532
Bios : 1.5-22
Powerdesk 5.52.015
Irq 9 alone, force agp2x (same with 1x)

Abit BE6II bios QJ
Celeron 366@550 (stable since oct99)
Micron 128Mo
HD 10Go IBM DMA 33 (boot)
CD 40x ASUS
HD 6.4Go QT DMA66 on the HPT366 (Irq 11)
SB Live value (Irq 10&5)
Adaptec 2940uw, IBM 4Go+Yam4416 (Irq 5)
Win98se
Power supply 300w Astec

Then, i put my G400 on a despro EP PIII500 at my office and i didn't see this problem (agp 1x) and the test with 3Dmark2000 was very poor.

very strange...

G400 16mo=low price=low quality ?

[Livius]

ffcia,

do you get those lines in fullscreen D3D as well? It is typical to the problem that we have been discussing here that we NEVER get those lines in D3D/OGL fullscreen, but only on the 2D part of the screen, even - or especially - when we run 3D in a window.

[jms]

If the problem only is a hardware conflict, it seems a little strange that it dissapeared when i popped out the 16MB SH(two different ones that is), and put in a 32MB DH. Sven, from the other thread, did the same with the same result. Strange...

[Livius]

No, I think it's not strange. Actually, Bixler may have a point. Any small modification on the G400 32MB part could do the trick. What's really amazing, though, is Haig's finding that RMA cards worked OK on their systems.

[DarkSyd]

Just to add another strange twist to things (possibly driver related?), I've noticed that the flickering no longer appears in 2d windows under Win2K, yet still does under Win98 and windowed d3d.
Just to recap...I used to get a really nasty flicker in explorer windows when scrolling or disk access.
Weird.

Haig-
I'll pack this thing up on Monday and send it back (before my RMA turns into a pumpkin). Or maybe to save some time I'll drive it down myself...anyone in the Sask/Manitoba/Ontario area up for roadtrip?

DS

[Haig]

If you're serious about a road trip, let me know in advance and you'll get the new board at the door. At the sametime, we'll pop in your board in our systems to see if we can reproduce it with yours on our end.

Haig

[Livius]

DarkSyd,

just to set things straight: does windowed D3D flicker in w2k or only in win98?

[The PIT]

Darksyd! If you're going to do the drive you might as well take your base unit and monitor then they'll have a live system to have a look at.
Thats if Haig would agree to it.
Unless of course you round trip is so long it's a case of drop it off and pick up a new card.

[DarkSyd]

Heehee, sorry guys, was just kidding about a road trip
I'm in the middle of Sask and can't really afford to take time off right now. I'm heading east this summer, but I don't think this can wait that long...

Fullscreen flicker under Win98 only.

Windowed flicker under 98 and 2000. I have to add that it is really bad under Win2000. Under 98 I would call it flicker, but under 2000 it is almost the same effect as when the vhold is screwy on a TV. Full screen lines spaced about 1-1/2" apart moving up the screen quite quickly.

I'm going to boot back to 98 to see if maybe this is just a case of the card about to croak.

[DarkSyd]

Yep, the full screen flicker is much worse under Win2000.

Haig-
If you guys want to pick up the shipping, I'll send my whole box (except monitor) down to you. I don't really think there's much point though. I've had the card in three other machines with the same results.
