No, the Nvidia cards don't have the same memory errors monitoring I mean have it but HWiNFO don't have support to read that.-

With a nice overclock it's probably ok. It's looking more and more like a 2nd rx480 would be a good idea. If only I could find a reference one for a decent price ($260 or under).

@kkiet There are p-state changes in the firestrike Ultra bench. I couldn't get through that without memory errors with an undervolt so I gave up. I'll I've to look at undervolting the memory again if you can. I'd also follow GekoTDF's advice about where to look for memory errors. The card changes p-states a lot in Metro Last Light and that does a good job testing for memory errors. I have to say they that the "ecc" can only find 1 and 2 bit errors. if the whole block is being set wrong I"m not so sure. That could be my problem.

@GekoTDF 2 rx480s overclocked to 1400. That's really nice. If and when I find another card I'll probably drop my overclock to about where you're at. I'd be worried about power use on the motherboard at my current overclock.

Well I don't check the motherboard, I mean, only the chipset temp and normal things - In my case I don't have a huge overclock like you have - but yes I recommend go down a bit the overclock with two video cards - I must elevate from 1.200v to 1.220 volts to compensate the Vdrop - So probably you will need to rise a bit, and you GPU Speeds will make a big power draw.-
Of course we are talking to reduce from 1460 to 1400 mhz its only 60 Mhz in... single card its a bit difference but in CrossfireX only 60 Mhz it's nothing and you win a lot of temperature control, low noise, and your motherboard will be very happy.-

OK....good to know. I guess when I get the new card it will open a slew of things I don't know. My son's rig has the R9 270X, but I really didn't do a lot with it when it was in my machine.

I plan on doing some testing/benchmarks with the RX470 though. I'm sure I'll have some questions. biggrin.gif

Thanks for the info.

I'm running 1435 at 1.235 right now. I'll drop lower though as I said I found a case where I go over 300watts total board power even at that voltage. I hope I don't need 1.22 for 1400 I think I can do with less. Mine seems less power hungry than yours. I'll do testing.

Powercooler Red Devil is in stock. Nice price. $265. Too bad they don't work with my block.

Well you have less voltage but have a better asic I think you will be a very lucky man if get another video card with the same asic points and in your case 91 if I don't get mistake, that's a very extrange asic for this video cards and that will be very important, in my case the two video cards have the same asic 71 and 72.7 percent.
But if you get another video probably will finish with 1.22 V in crossfire because 1 of the video cards will need a bit more than the other.
Well all this in theory of course but take in care

Only some maybe only Polaris reports the memory errors, I have not seen it myself in HWiNFO for 280x with GDDR5. You just have to test and see what setting gives you highest performance.

---

Would anyone be so kind and measure the height of the reference 480 VRM section? I think the chokes are the highest, if someone can measure the height of them that would be awesome. While at it if you can get the measurement of the distance of VRM capacitors to the heatsink mount holes.
I know one custom cooler doesn't fit because of these parameters and I would like to know how much it doesn't fit since it's possible to bend it to make more room and fit it.

Speaking of coolers, what AIO water coolers do you use or recommend for use with GPUs especially the 480? I don't care for mounts so zip ties, custom metal mount, ...whatever, is acceptable to me.
I like the Arctic Liquid Freezer 120 but it is so hard to tell with AIOs if the baseplate is flat or concave. This is more of a curiosity since AIOs are so damn expensive.

Im using Maelstrom 120k one per GPU.-

What is the cheapest you have seen Sapphire 480 4GB Nitro (11260-02-20G) sell for? While I do not like the cooler and all, I could get one for a decent price I think but not sure since I don't know what the prices of custom cards are supposed to be when not hiked.
I found one for what looks like would be $219 in US. Which IMHO isn't bad for a custom card +20 USD for a cooler and higher frequency.

I've inquired again for more 480s and the reference 480 8GB but it was going for around $245 which is heck of a price increase compared to 4GB custom version hmm, say +$25 for +4GB but lack of cooler... and custom Nitro cheapest is $264, so that's +$45 for 4GB VRAM? The hell.

I do use 1920x1200px but I have no problem finding games that go past 3GB on that resolution...

Tempted to snag the custom 480 4GB even if the cooling is not that great. Custom 1060s are $262. Custom 480 4GB seems like the smallest investment. There are no cheap 470s, the Platinum is $189.
There is always a huge price increase when it comes to 470 => 480 and 4GB => 8GB.

Sorry, im from Argentina can't help about prices.-

Well I was working with the Crossfire and see a few things to take care with the overclocking software.-

1) Make sure in Wattman you have from stage 4 to 7 with 1175 volts in both cards you will have two wattman's all the other things "default" - That's the way I find Wattman don't make a Vdrop if you need more than 1.175 volts and that it's pretty normal.-

2) Disable ULPS that's very common in overclocking world - this basic turn off the second video card until it's necesary the problem with this is, the custom voltage and overclock will not be apply because at the moment of the apply the video card is "off" so ignore it - The same with HWiNFO for example you not see the VDDC or in the case of GPU Tweak II not apply the voltage.-

3) In GPU Tweak II, just make sure the two video cards are "Sync" for settings it's default but check, select the first one put all the settings, clock, fan speed, etc, apply and save the profile - That profile will be the apply everytime you open the GPU Tweak II (if you set in settings) - Make sure you don't create a second profile with the other card or something like that.-

---

That's the way you get the same GPU Freq, Mem Freq, fan speed, voltage, and all that stuff.-
Remember if you reinstall the driver or update you will need to disable de ULPS again and check the Wattman voltage (usually not go to default only if crash).-
It's not a problem disable the ULPS, the video card it's in idle too, the only difference it's you waste 30W and a fan running almost nothing.-

---

In another way I was incorrect in some way about the need to up the voltage in CrossfireX, my problem was the second video card don't have the correct voltage I fixed with the guide above - In single card I use 1.20v at CrossfireX 1.21v that's with the vdrop it's real 1.20v.-

And finally I discover the second video card have a few memory errors with the same mem freq, so I reduce the mem freq from 2170 to 2135 that's probably something related with the CrossfireX and memory management.-

I retested the farcry 4 power use situation. For whatever reason. Maybe different settings I only measured ~248 watts. Used SMAA and volumentric fog and hbao+ with very high settings. On stock with power limit set at 0 I get 319 watts total system power. So I'm fudging and guessing 155 watts of that is the gpu. Then I I set limit to +50. I'm running EMBD so that's really +100 I think. I get 353 watt total system. So that's 189 watt total board power. Then I apply my 1.235v vid and 1435 overclock Total system power goes up to 412. (I was getting 460 before. I'm not sure what's changed.) Anyway I get a much more reasonable 248. I will retest. I didn't apply my memory overclock. doh. .....

moved memory up to 2200 (previously I'd done 2210 but I wanted a bit of a safety margin) Measured power use of 449 watts. Wow that's 37 extra watts on the memory and memory controller! What the hell? So total board power hits 285 watts. VRMs hit 80s really quickly. What's going on here? Why is memory using so much power?

I switch it from smaa to msaa8 and the power usage goes down to 370 watts. Every other setting is the same. So SMAA in Farcry 4 uses 79 watts! Anyone have any idea what's going on? This is using more power than FireStrike Ultra stress loop.... Not sure why. It does make me want to reapply thermal pads to my VRM and re-TIM my gpu.

edit: SMAA looks better subjectively than the MSAA and the frame rate is so much better, but I don't understand. Why isn't the card throttling the power use? I"m way past what even embd should allow. I think. Anyone know?

SMAA runs on shaders, MSAA who knows where I don't remember. That's why SMAA may be more power hungry.
