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.

Remember Mr. Grey when I say don't go more than 1400 mhz and more than 1.2 volts or you are going to have high Temps in VRM and the power draw will go to hell, well that's your escenario.
Now do what I tell you put 1400 mhz and 1.22 volts or less, the mems at for example 2150 and test, you will see the difference

I understand. It's just that one scenario. Even Firestrike Ultra stress loop is using 40 to 50 watt less. It should be power limiting this. But it's not. I'll drop my memory overclock a bit for this game is all. It's stable and nothing is burning, it's just a bit worrisome. Even Metro Last Light is power limited and changes p-states and uses much less power than this.

Not all of that extra usage will come from the GPU. FPS scaling with memory frequency is nearly linear, which pushes the CPU harder to keep up. You also have to factor in PSU and VRM efficiency, and even higher GPU utilization (despite the usage always saying ~100%, that's really just the scheduler's usage, not the shaders, ROPs, and so on).

In the end, the VRAM is probably using 10W more power, and the other 20W are from the other factors I mentioned.

As for your sudden increase in VRM temperatures, it's probably because you exceeded a point of thermal equilibrium related to the thermal conductivity and dissipation of the materials used to cool the VRMs while at the same time dumping in more heat and have entered into the first part of the exponential temperature response curve.

Still, 80C VRMs are usually nothing to be concerned about, even for 24/7 usage, though they become less efficient at sending current as temperature increases - which adds to even more heat being generated... It's a vicious cycle with many feedbacks.

My VRMS are about 15 degrees hotter than they are in firestrike ultra stress loop. Just saying. I used to think that was the worst case scenario. The review sites all use that and Metro Last LIght as the worst case for power usage in-game and firestrike ultra stress loop as the ultimate worst case for power usage. It should be power - limiting the power usage. I'm wondering if it's not factoring in compute tasks as part of the power use or if it's a bug just for this game. I set the power limit to 25 which should be the same as +50 and my power usage only goes down by 10 watts with smaa. So 275!

at power limit 0 it goes down to 230 watt. Still way past where it should be for power limit 0, but it's reasonable. I get better performance than with msaa8 and power limit 50. It looks slightly better subjectively to me. (while stationary.) Frame rate is in the high 70s rather than the 30s with MSAA8,

edit: I'll retest FireStrike Ultra Stress Loop to get exact power usage there. I'll also get gpu and cpu power use from hwinfo and gpuz. I noted a few pages back looncraz's concerns about my methods not taking into account cpu power. My cpu is back down to 4.9 from 5.0 and 4.6 ucore. I'm running 1.385 on my 4790k. Cpu temps were in the 30s and 40s when I was running the tests so I assumed cpu power usage was minimal, but I didn't check. I might not get this done today. I kinda want to get some actual gaming in. lol

I was wrong. I checked my VID I accidentally had it set for 1.221 I'm surprised I was stable. That explains why I was 20 to 30 watts lower than last time I tested.

Got a reply from a shop in regard to reference Sapphire 480 8GB, taken down because they cannot get it from their supplier. Of course they skip the rest of the questions about other brands and cards frown.gif
But the XFX finally showed up at the biggest and overpriced shop here, really September is IMHO the 4xx launch not July nor August gunner.gif
And prices moved up again and lower elsewhere... shops change prices sometimes by the freakin' hour.

Anyone knows how long will the reference cards be made or if it's the end of them especially at any reasonable price? It seemed like at least one of them dropped down in price and now it's gone from shops before even being available at many shops at all.

Stupid rushed launches.

Usually are not a lot of time after the release, the problem here it's AMD can't provide all the video cards (reference) - So it's a particular case.-
But I am sure you will get a reference card above the time without problem.-

And... well you touch the topic - It's a really shame AMD fail in the provide of the video cards, was a amazing project, good price, good performance, good campaign, but...fail in the distribution - Im sure they not lose money, I mean, all the video card's they waste to build recover the money very fast - But I think this video card series was a good chance of recover some type of market - I read a lot of time people who decide to buy Nvidia because this video card's never get to shop so they get tired and buy another thing.-
For another point of view, probably they not fail at the build provide, I think they don't spec this amount of sell's and don't spec the sell's to mining people - Yes crap but a sell it's a sell and AMD it's a company so, probably in monetary way they are good, but the real clients probably lose, like you the possibility to buy one in a short time - And it's going to be very reasonable get tired.-

But with patience you can get the way to roma (?)

The MSI GamingX 4g is in stock at Newegg for 249 this morning. The asus 4g oc card is in stock at 229. It's not reference though so probably not unlockable to 8gb. I'm waiting for a reference card 8gb to be available again at a reasonable price. Why should the Gameing x 4g be 249 and the 8gb be 289 but the cheapest reference card 8gb in stock be 300+ I guess I'll have to wait longer. I check every day. I found one reference card for 275 online and I almost went for it, but that's still quite the premium and I wasn't sure about the seller.

Yeah Grey here the same some shops have cheap listed reference 480 8GB but not as cheap as this shop near me had it ($244). Most of the time the reference were listed but never available and stuck with their $285+ prices.
I'm looking into 2nd hand coolers so that was why I had my eye on cheapest reference 480 8GB.

Sure I could preorder a 480 4GB Nitro for $215 and screw it, but they come with the crappy Hynix VRAM and subpar cooling frown.gif
I am also vary of sellers, shops, there are some cheap, I've used one before and wasn't happy with their customer service at all so the cheapest is not always the best option to take.

I have no idea how AMD is able to supply so few chips and doesn't take into account that this is the biggest launch in several years because both NV and AMD were stuck on 28nm of which people honestly grew tired of to upgrade to again. Every AMD launch was a mining crisis and 4th time they still do not take it into account when it comes to production? From what I know they had spare wafers from GF for years and didn't use them because the CPUs and GPUs were made at TSMC, and now what, can't punch out enough chips at GF? It's the same process and fab as Samsung, why not buy bigger capacity at another facility that uses the same process at least for the initial launch?

My education in supply chain management is not big but come on, this is ridiculous AMD.

Yes Gecko, there are many people who rather go and buy a 1060 for $259 than get an overpriced 480 for $289 if it is even a custom model at all. I've seen it on reddit where people made this decision and I myself am always tempted to but then another NV driver stutter issue person I come across and get discouraged.

All I ask of AMD is to provide 480 8GB with a robust PCB design so it doesn't go up in flames like PowerColor Devil and costs the same as 1060s which sell for $249-259, no one wants the more expensive 1060s beside way too rich people that do not know a thing about what they buy.
Here everyone wants that single model of a custom 1060 from Gainward $259 because that is the only cheap dual fan custom 1060 here. All those $249 MSIs etc. are an illusion and cost way way more.

I bet AMD is selling a lot of 4xx cards but many again ended up in hands of electricity wasters/miners not gamers.

I have notifications setup in shops, check about 10 shops in my country and in a neighboring one to see what is available, where, how many, for how much. Until prices settle down with supply recovering it doesn't make much sense to jump on expensive early deals.

A friend ordered an RX470 Nitro 8GB for 215€, but he get the 4GB version in place and Amazon offered him a 40€ discount for future purchases. I ordered the same 470 and I think that most likely I wil receive the 4GB version. My problem is that I play at 1440p, not at 1080p like my friend. 175€ is a good price if they offer me the 40€ discount but the bandwith and the VRAM.... What do you think?
