Help Msi Hd 7970 lighting weird artifact when overclocking.

post #1 of 10
Thread Starter 
Ok when I overclock my card with cc or afterburner or trixx any kind of bump to core clock it shakes the screen and artifacts like crazy. Now if I use GPU Tweak I CAN GO UP TO 1175CORE CLOCK AND 1500 MEM and run heaven flawless and I played Fc3 for two hours flawless no artifats or shacking of the screen. I off couse verified my clocks with gpu tweak. I did not touch any voltages just power to 20% . My problem is I would prefer to use AFTERBURNER OR TRIXX I did not see any where to set voltage in gpu tweak? I also raised MY 2D clocks to 500. Is there something wrong with my card ? I have tried the xml trick and unofficial overclocking meathod twice no luck . I can also overclock in Gigabytes EASY6 BUT no voltage there either. So please help me if possible figure whats best to use that I can play with the voltages. The Rig in question is SIG RIG.

7900 series cards can be pretty tricky to overclock. It literally took me WEEKS of troubleshooting to get my card where i wanted it. I'm going to give you some advice that sounds weird, but it worked for my diamond 7970 and improved stability IMMENSELY. I am currently overclocked to 1235/1700 and stable @ 68c while furmarking. I could probably raise it to 1265/1800 but right now I'm very happy with the current performance increase and don't wanna screw anything up.

Before you do any of the following, please uninstall all drivers and all overclocking software, then do a clean reinstall.

First of all, never ever ever ever use unofficial overclocking. I tried that like you and it killed my performance and gave me artifacts as well. you need to do all of your overclocking of frequencies in the CCC, and your overvolting in MSI AB. Don't touch any other settings except the voltage in MSI AB. If you were like me, and didn't like CCC limiting the frequencies to 1125 and 1525 (i think), perform the /xcl command with an msi ab shortcut. If you have no idea what I'm talking about, google "msi afterburner xcl command". After doing this, you'll need to restart your system. Now open up your CCC and you should be able to raise your gpu and ram much higher than before. Don't make any super huge increases at once, and only raise one frequency at a time (don't make changes to gpu and vram at the same time). This eliminates as many variables as possible that could be causing artifacting. I would recommend starting @ 1000/1400. Keep raising your gpu OR vram (i recommend starting out with the gpu) while running a strong benchmark, waiting AT LEAST 60 seconds between changes before making new ones. Don't make huge changes (maybe 5-15 mhz at once). Keep doing this until either you notice stability/fps decreasing, or artifacting. Once either starts to occur, close your benchmark immediately and go to your MSI AB to raise the voltage, then restart your benchmark. Make sure to keep your benchmark running while making frequency changes so that you know the exact frequency that causes instability. I can't really give advice on where your voltage should be, but i recommend an increase of .025 once you notice instability/artifacting. My voltage is right at 1.275. Once you've got your gpu where you want it, run a 10-15 minute STRONG benchmark to ensure stability and reasonable temperatures. For vram, basically the same thing, though raising the ram frequency might not ever cause artifacts, it may just cause a complete system lockup, so make sure to make small changes to that as well. Remember that having vram too high can lower your fps. It may sound like a crapshoot, but it should work fine in the end. If you have any questions just PM me. I've spent a LOT of time figuring this out and am very satisfied with both of my 7970's in crossfire @ 1235/1700. Furmark score: http://www.ozone3d.net/benchmarks/furmark_192_score.php?id=104644

EDIT: When checking your frequencies for temperature stability, i highly recommend running the benchmark until your gpu temperatures stop raising altogether. Mine stop raising @ around 68/69 c with fans @ 80%.

It's a pretty easy fix. 2nd post at the bottom, that flicker should look rather familiar to you.

Jason when I get home and try your suggestion. I will also run furmark and post my results. I can not believe that these cards are so much a pain to overclock it boggels my mind. Thanks for the advice+REP GOOD SIR

Furmark is useless for testing anything other than heat checking. The app is throttled by the driver anyways making it a relic.

Thanks a Million yes it does I thought at first I had a crappy card.

No problem bud. Don't listen to that dude trying to say i don't know anything just because I have a low post count. The best advice is always advice that comes from people that have had the same exact problem as you, and found a very good solution to the problem. Unoffical overclocking is not necessary and causes instability for a LOT of people. I'm just trying to save others from the BS i had to experience while trying to get what I wanted out of this card. Good luck and PM me if you need help. I'll help you directly rather than point you to more forum threads, which you've probably been reading for a while already trying to find a solution like i was LOL.

Lmao, yea I don't know what I'm doing but you do. doh.gif


You're asking ppl how your bench numbers look in Furmark. Furmark, rofl.
