Even though I have a AMD 6970 sitting on the shelf just waiting to be used, I find these claims hard to swallow. I want to believe... I need to believe :( . I've got the framerates already. What I need is a "shimmerless" view. When you guys are saying no jaggyness are you really saying no shimmering? Or are you saying this is an AA thing? It just seems a little "volt jolt" would have such an effect. But please convince me. How about some before after shots or better yet before/after video.

Clutch, there is nothing to convince you about. I have a 5970 and you have a 6970 they are not the same card. And as you see here: http://www.youtube.com/watch?v=twM0vtKME7w, the 5970 a much faster card - its simply raw power. You are not going to get the results that I posted here unless you wat for the 6990 (whenever that comes out - which rumor has it will still be based on the 5970). SO To be clear, this thread is about the 5970 ONLY. I make absolutely no claims regarding ANY other ATI card! BTW, jaggies and shimmering are two different things and I have neither.

I had my first blue screen of death and I'm thinking it has something to do with this.MSI Afterburner couldn't let me choose 1163, so I choose 1174 (the closest number MSI Afterburner would let me choose after 1163)I have reduced this to 1162 hoping to avoid the blue screen of death. Not sure if this is a sensical approach. Any suggestions Mike?

Remember the max clock for the GPU will differ between systems according to Motherboard, Memory type and speed, CPU and the quality and size of your power supply. Your problem is not the voltage, its the clock speed. Leave the voltage where it is.You should be using a tool like Furmark or even the CCC overclock test tool to verify your GPU overclock is stable. If your rig fails a GPU test then throttle down the settings (GPU and Memory speeds) until your rig passes a full round of tests. I think that if you are getting BSOD then your rig cannot keep up with the GPU at that speed so drop your settings at test, test, test!Also, what are the specs for your rig?

Mike,I did test it using Overdrive and I am stable. Maybe the blue screen of death was a fluke? Ran one flight yesterday and didn't get it again.My specs are: i5-750 overclocked to 3.2 ghz, ATI HD5970 (of course), 8 Gigs of ram, Windows 7 64bit, a fairly new motherboard that I can't remember the name of (Asus?)Thanks again.

Ive asked the mods to delet my account...Yea!!!!, Ok anyhow for old times sake...Mike just to straighten this out for all who may read thru this thread, those benchmarks are good crossfire results for those programs but FSX wont see that, In FSX the 5970 is not even close to a 580GTX or even lesser single chiped NV cards like the 480. Here is why: The 5970 is simply two 5870 (2x RV870 chips on one PCB), Since FSX is basicly only using one of those, what you have is nothing more that a tad bit slower 5870 (same results for NV two chiped cards like the 295GTX etc). Second, please dont talk about quality untill you have had a good nv card to compare to esp when talking about shimmer and quality AA as far as FSX, sorry but its true.Oh and BTW Overclocking the GPU hardly does squat in FSX, 580GTX overclock extremely well as do 460/560s, but it matters not as far as FSX is concerned.You guys take care.

Although I have a VERY lowly spec to most of you (ATI4770), Mike has identified something of great value to me. The overvolting tool has worked a treat on my system - I was unable to overclock my card at all before (BSOD, lockups, the usual), with the tool I certainly can, and now I have a much more fluid FSX. I'll need to quantify this with some benchmarking. But for the moment, thanks Mike as this has helped greatly.To the previous poster, not sure how many of here have the means to compare and contrast between ATI and NVidia cards. Don't knock the o/p, he's identified something very useful.

As far as I read it , it seems that oc the ATI card might deliver some fps.If this "guest poster" is who I suspect he is , he knows almost anything there is to know about OS and FSX.....

I ordered an Alienware Aurora a year ago with a 5970HD, 2.6GHZ i7 and 12gb ram.I have had problems off and on, and have frequent driver crashes if I turn on aircraft casts ground shadows and/or ground scenery cast shadows. I had a serious jaggie issue for a while, but fixed it by following Nick's settings and adding ATI Tray Tools.My last driver upgrade was to vs 12.x and with the new CCC I did not reload Tray Tools. I have been getting fair FPS except in graphic heavy areas like SEA-TAC with FTX PNW running. I also have REX, GEX, and UTX. I tried to OC using MSI Afterburner but everytime I move from Core Voltage to Core Clock, Core Voltage reverts to default.I tried setting the voltage and saving, but no go. It always reverts to default. I can OC using CCC, but without the voltage change, it is unstable and crashes the driver. Any ideas? BTW, I never got above 875/1125.

I finally got MSI to work. I was typing in the numbers instead of using the sliders. So even though the instructions say you can do it this way, it did not work for me. I had to use the sliders and once the slider was activated, fine tune with the arrow keys. I also could not round up to 1.163, it would go to 1.174 when I tried to save it. I had to go with 1.162. And I'm still running the fans on auto. Temp never went above 76C.I got a small improvement at 825/1125 and a good bit better at 875/1190 and it appears to be stable as long as I leave shadows off. It did not solve my driver crash with shadows on.I am getting some anomalies on my 2nd monitor that I use mostly for FSWidgets GMap, but it is not constant and I can live with it.
