About the Mem freq, I discover something you can try... Less voltage you put, more memory freq you can get... don't know what the hell happends - But the story was when I discover this "insulate" problem in the GPU, I start the overclock again from 0 was very quick we now have the experience, now the drivers are more mature, and all that stuff.-
I get 1390 mhz core (may be 1400 mhz don't try really not time this week) with a real 1.81/85v - In the past I use 1.20/1.22 real voltage, don't know why I use so many, I was doing the things wrong - But anyway, with that high voltage The max mem freq I get was 2135 mhz without errors - But now I get 2160 mhz without errors and that it's a improvement - Of course from 1.21v to 1.81v it's a HUGE difference in temp's in GPU and VRM - So check with 1400 mhz - that's my recommended max sweet point of this video card, and the less voltage you can get, try with 1.75v real (thats 1.85v in GPU Tweak II) and test with Unigine Heaven or Valley (for crossfire) then for stability general use Firestrike (not neccesary ultra) If pass OK with 2135 mhz of Mem, use Metro Last Light and start to rise the Mem I am very sure if you are using less than real 1.85v are going to be able to get 2150/2160 mhz of ram freq.-

Another thing to take in mind be carereful with the CrossFireX and the voltage of the second card, don't know why, but here in my PC the second card by default its detected in the stage 7 with less voltage than the primary (I talk about this but I repeat) the problem with this it's you are going to sync the two video card in any overclocking software but the second will have less voltage in my case the difference it's 50mV a lot really.-
I have constant crashes with the CrossFireX then I see that problem - Remove the Sync option in the GPU Tweak II and manually add 50mv to the value of the primary card voltage in the second one for example my primary it's in 1.212 (real 1.81/85v) and the second one 1.262v (real 1.81/85v) that's because from default have a difference of 50mv , and problem solved perfect voltage in two video cards.-

I can't stand Asus GPU Tweak II. I had really bad luck with it. Failed overclocks shouldn't persist into lockups on reboot. At least the built in wattman is smart enough to reset. I use BromoL's wattmon almost exclusively. I'm running 1.175v for my first card at 1400. It's Heaven stable at 1.17 but I need the extra 5mv for Deus Ex/Metro. I feel a lot safer than my 1.236v at 1435. I haven't tried the 2nd card at 1400 yet. The block wont get here for a week. Right now it's living in a old computer running office stuff and casual games. I'll put in my gaming system when I get the block. Looking forward to fiddling with it.

You run GTA V with your crossfire setup yet? That's probably what I'm playing next. 24 hour download! It's like I'm back on my 2600 baud US Robotics grabbing Police Quest discs from my local BBS. Looks like if I'm willing to go fxaa rather than msaa and maybe make a few small compromises, I might be able to do 4k on crossfire rx480. I'm not positive but this looks like another deferred render game with huge msaa performance hit. We'll see. At 4k I'm ok with aa off. At 2k I'm fine with fxaa. I'm at 7 feet from my display.

edit typo on voltage. 1.17 and 1.175 rather than typo of 1.7 1.75 I think you had a similar typo with your "1.81"

Time Spy: 7.133
Firestrike: 13.331

CPU: FX-8350 @ 4.5 Ghz
Core: 1390 Mhz @ 1.81v (Real 1.75v/1.80v)
Mem: 2160 Mhz
CrossFireX: On




Not bad at all though that does show the 8350 bottlenecking a little hahah

Ah Yeah probably in Asus Tweak II - If Fail it's a pain in the ass to get it work again - You Try MSI Afterburner ? works fantastic, my problem it's I have this voltage difference in the two GPU and the slider of voltage of the second card it's not enough - So i decide to go to Asus GPU Tweak II Again.-
GTA V? - No, I never downloaded - But that game it's very CPU sensitive, and I'm running with a 8320 overclocked, and my FPS will be different, probably 8 or 10 fps than yours.-

About the voltage yes, I make the mistake jaja too much numbers for 2 AM.-

Jaja yeah syntetic benchmarks usually are more sensitive, but in practice I have everything limited at 60 fps with freesync so... still can get 60 fps en almost all games, Im thinking to buy a i5 6600k or wait to AM4 - I don't really know about.-

Only when throttling kicks in, you will have reduced power cosumption.

 

You are correct, this is my error.  I was under the impression that giving the GPU a larger window for power draw would allow it to keep pulling until it hit that target/limit, regardless of if it needed it or not.

 

After some quick and less than ideal testing, I see that my logic was wrong. 

 


 

I ran Time Spy benches with my GPU at stock settings only increasing Power % in 5% intervals. I was able to find the lowest PT% that gave me the maximum graphics score for stock clocks.

 

Here's the breakdown:

 

  • 0% Power - Graphics Score 3895
  • 5% Power - Graphics Score 3937
  • 10% Power - Graphics Score 3983
  • 15% Power - Graphics Score 4027
  • 20% Power - Graphics Score 4050
  • 25% Power - Graphics Score 4061
  • 30% Power - Graphics Score 4059
  • 35% Power - Graphics Score 4058
  • 40% Power - Graphics Score 4058
  • 45% Power - Graphics Score 4060
  • 50% Power - Graphics Score 4057

 

The plateau was reached at 25% as there was only a 4 point variance in graphics score thereafter.  Increasing the PT% and nothing else is good for ~4.3% boost in performance for Time Spy.

 

I then ran Time Spy a few more times, but cut the benchmark short immediately after graphics test 2 completed.   This allowed me to get an average power draw value through GPU-Z for only the graphics tests.  While this is far from perfect methodology it gave me the desired results.  

 

25% Power Target

 

50% Power Target

 

 

 

The difference between average power draw for 25% and 50% power target was 2 watts.  

 

With a lengthier duration and better methodology to take power draw values from, I would see that variance disappear.

The fact that the bench didn't manage to finish means you still have instabilities and shouldn't be drawing conclusions from these results. Also, +- 10 points is within the margin of error of 3DMark, also not indicative of performance effects.

You didn't read my post entirely.

I hit the ESC key and forced the benchmark to stop. There can't be any stability issues when the card was at stock settings aside from increasing the power target.

I know +- 10 points is within margin of error, but it also clearly showed that increasing the power after 25% yielded no benefit to the core clock holding steady.

I assure you my card is stable at my maximum clocks...I have posted results from it completing time spy and other benchmarks in numerous different overclocked states.

I know +- 10 points is within margin of error, but it also clearly showed that increasing the power after 25% yielded no benefit to the core clock holding steady.

I assure you my card is stable at my maximum clocks...I have posted results from it completing time spy and other benchmarks in numerous different overclocked states.

Ah, I see, sorry for misunderstanding.

Quite alright.

As I stated, it is far from a perfect way to test. With the variance in time it takes to open GPU-Z, choose average values, run 3DMark, stop the bench and get a screen shot...there's several things happening that can add/subtract time to the whole scenario and effect the average values displayed. I canceled the bench after the graphics test because the physics test is entirely CPU bound and it only lengthened the time to run everything numerous times consecutively.

Imperfect as my timing/testing may be, if there was going to be a large difference in power draw values it would have been made apparent.

I've had some crazy high spikes for GPU power draw during gaming not sure why or when it happened. Not saying it's very relevant, but just thought I'd throw my 2 scents at you.. They're pine and "new car smell" if you were wondering biggrin.gif (badum-tss)

Occasionally I dip into upper 40s, but it doesn't seem to be npc related. It's very random. Again, that's at 2k with 1 rx480 with my oc turned off. Luckily frame timing is very good it seems in fallout 4. upper 40s still looks pretty smooth compared to other games at that fps (looking at you Deus Ex Mankind Divided.)

I just recently learned about CPU OC, I haven't messed with RAM since it can kill my whole system. My mobo can only take up to 1866, currently have 8Gb of 1600 in it. 80% of the time I have 50-60fps but when I'm in heavier areas (Diamond City etc) fps drops drastically and my CPU ramps up to 85-100% even with the 4.6Ghz OC on it. I will admit I don't 100% feel confident in my OC skills so there may be something not set high enough with my OC or something. Sapphire Nitro+ 470 8Gb card on stock, when I hit any area that's highly GPU bound I get great framerates.

I need to go through the programs that are constantly running on my PC and figure out which cause more CPU useage and disable them while I'm gaming, I have a little "monitor" that I attatched to my case, so I can watch temps, clock speeds, and useage while I'm in fullscreen gaming. Not sure if it would affect anything as far as useage goes or not.

Also my W7 could more than likely be optimized for while I'm gaming because I know it pulls a decent amount of resources itself just running in the background.
