[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 695

post #6941 of 38701

Here is another review posted by El_gappo (benchmark editor). I think at top OC level (that's what overclock.net is about right thumbsupsmiley.png), the AMD 7970 is still the king, also the 7950 is right behind.

Look at the first OC review, they are even pretty much. 680 OC'd to 1335 or something silly. 680 gets pounded in all the compute tests though.

Once you've run a game at that res, it will load in single screen res even with eyefinity on, so as I go to ingame change the res for widescreen, BAMM crash BSOD 116.
So after I tired of playing all the uninstall/install tricks, I went with a different driver, 8.960 leaked beta OpenCL driver. The result is a mixed bag, BF3 now works in dx11, but there are still broken parts to this driver. Synch with DP and DVI is off, so I always have a flickering bottom portion of the DP connected screen. That's better than making the single DP screen primary lol and having two flickering DVI screens, lesser of two evils. mad.gif
Now if I could mod rc11 eyefinity control into these 8.960... hmm maybe I will reinstall rc11 and manual update 8.960?

I played BF3 in Dx11 and Eyefinity for 1/2 hr last night with no issues, no flickers, actually not one bad thing to say except I had to go to bed lol. I'm waiting to get out of work so I can test a little more, just wanted to see all my games launch and play well and they did. Now lets see how long.

HA, I like that Overclock3D review. Overclocked, 7970 holds it's ground well. FrozenCpu, I need another Acetal/copper block please biggrin.gif

And the kicker is to get to 1400mhz on the 680, you have to absolutely hardmod it to replace NV's craptacular vrms and use the Evga board. You don't have to do this with any AMD boards lol. It's not clearly a slam dunk on the extreme front. I'm thinking things will change when you look at a tri or quad 7970 setup pushing 1300mhz+ unmodded.

I don't know whether it's worth me trying to troubleshoot this stupid thing at the moment or not..about to platform switch (the right direction!) from an 8120 to a 2600k. I'll have to mess with it later I guess. Tired of troubleshooting this god forsaken bulldozer debacle.

If you fancy getting more cards whether they be red or green, you'd want a better cpu. Look at the incoming z77 boards, especially the P8Z77 WS. thumb.gif

Finally found a link to the almighty RC11 driver. Will give it a try when I get home and see if that fixes BF3 in-game environmental flicker.

I've noticed that these cores like a fair bit of juice to make a jump in core clocks. It could just be me, but I've had to push more than a few increments at a time to hit X clock. So what I did was just push max voltage and worked pushed the clocks up to hit my upper boundary. Then from there I worked my way down. You also want to get an idea of your vgpu droop. Fire up hwinfo64, disable AB voltage monitoring in your OSD and run furmark. Furmark is great for loading the gpu and hwinfo64 for watching real time voltage. Write what you put into AB and what is displayed by hwinfo. The difference is your droop. If we calculate from your stock vgpu which is 1093mv +125mv = 1218mv is your max before OCP kicks in. I'd guesstimate your real max voltage to be somewhere around 30mv less, 1188mv.
Now here's the kicker. 125mv "IS" what AMD has deemed safe, since that's the limit they set. And it would be logical that they've set it actually lower than the true limit as to provide a cushion for safety margins.
Ok with that aside, go see what your max vgpu droop is.

Thanks for taking the time to help me !
That core test I did was indeed at 1175mv. My True stock voltage = 1090mv. Asic = 76,3%

I did a 1 minute test in Furmark at 1150 core / 1520 memory @ 1175mv in Trixx (not using Afterburner) :

So in Trixx is 1175mv and I see : 299

1157mv it looks to me...

Now what do to next? smile.gif
