If you leave the voltage at "auto" it will automatically scale the voltage up with clock speed. You can verify with GPU-Z.

Found GPU-Z reporting the max voltage supported by my card when I first got it. 1300 was pushing 1158mv without me touching a thing other than core clock speed.

@Hequaqua

On 16.7.2, which you can't run,I get very good scaling for memory frequency increases. There appears to be a bug in in 16.8.2 drivers that give some people, myself included, negative performance scalling with memory frequency increases. We were setting our gpu frequencies to 1000mhz across the board and testing our max memory overclocks performance vs. stock memory to see if we have the same issue you exposed with your heaven scores. We were just looking for the heaven scores at your various memory frequencies with gpu throttling taken out of the picture. to be posted over on Loon's thread for the issue you exposed. http://www.overclock.net/t/1609366/amd-16-8-1-16-8-2-memory-clocks-not-working As he's sending a link to that thread to AMD with a bug report. We have 3 others so far with the issue.

OK....got it. I can run 16.7.2, but the highest Vram setting is 1800mhz. I didn't mess with it really.

Here is what my son's card looks like running BF4:


That the end of a round, then a full round. I actually did pretty well. The fps was around 115-135, that was using the "suggested settings". I think most of the settings are medium. Looked good.

I'm going to do a little testing in the morning. I'm going to try to see how loud it the card is at idle/load. I don't have anything to really measure it with. I can compare the sound to what I hear with my 970.

Hi guys, I'm really interested in RX 470 4GB.

My current rig ir really old, i5 750, 4 Gigs RAM, GTX 285 (Nvidia ones!), 600W Power Supply.

So... is there anyone here with somewhat old rig can tell me how it performs

I've heard that for older rig, it's better to buy Nvidia, but I really want AMD since it's more 'futureproof' and can be crossfired in the future.

Thanks, hopefully this kind of post is allowed.

New APIs don't need CF or SLI for mGPU but solely rely on developer support, which is likely to be poor/none due to time needed to invest into a config that 1% or less people actually use.

There are some reviews with older CPUs gotta search.
AMD cards aren't future proof. The Tahiti was better than 680/770 on launch but short in supply so many went with NV. Hawaii was good too and stomped on the NV cards even though it was an insane power hog. Got a little boost with 390 series VRAM and better clocks, cooling and driver optimized for more games to utilize the GPUs more. On the other hand the 970/980 consumed a LOT less power for the same performance. Fiji... I call it a technological marvel, nice but power hungry and only a step better than 390 series and not enough to pounce 980Ti/Titan.
Now AMD has the 4xx which is in very short supply, decent cards but again power hungry due to the architecture and needed die size/transistor count, is often not utilized by developers fully, follows the same 490 vs 1070 so a 480 goes against 1060 now unlike generations before it would be against 1070. Pascal is Maxwell on speed, efficient and fast, stripped a lot. The 1060 has no problem currently to run away a little even from the 480 8GB except in DX12/Vulkan games they tend to be neck to neck but then there goes the availability, price and OC ability none of which go in favor of AMD offerings frown.gif

I've been waiting for AMD supply to recover for 2 months and so far nothing. Prices are locked for weeks, XFX barely showed up this week listed in shops, overpriced as other cards as shops still believe 8GB is better than 6GB, short supply so they charge up $25+.
The 470 4GB is a nice card if you can find it cheap, for me the 480 4GB makes more sense since it's barely any expensive than the 470 4GB. $211 for 480 4GB Nitro but preorder for how long I don't know. I find 4GB low these days and the 8GB versions are all overpriced and rare in supply.

Hence I got 1060 6GB ordered just now as their prices are about to go up due to very high demand as it is a card everyone is buying in Europe beside the 1070s, it's the most popular Gainward/Palit $259 model, should be available for pick up in 3 days, will probably pick it up on Monday and see how it runs. Not overpriced either, $259, it was only once discounted in one shop for a short time to $254, now most hiked it to $269 because of supply/demand and cards flying away instantly.

Here is a review that has the same exact CPU as you have. Doom for example is AMD optimized yet the CPU is a bottleneck there for the 4xx. And that is on Vulkan as you can see in the text and with 6700K the 480 does the typical 120fps@1080p but with older slower CPU the GPU performance on 4xx tanks even with Vulkan.

Maybe digital foundry made some YT video with different CPUs too.

All things considered: price, availability, current performance in the price range across all older and new titles, OC ability, temperatures, noise, ...
The 1060 seems to have an edge over 480 for me and the only reason IMHO to buy AMD 4xx is if you have a FreeSync monitor and use FreeSync or plan to buy and use a cheaper adaptive sync monitor. The Gsync ones are expensive and I dislike Nvidia for doing that proprietary crap but can't help and see that their cards right now are indeed better and that is what it always is for me: performance/price.
The 480s should have been more available and cheaper than 1060s and I would have bought one 2 months ago no hesitation. AMD screwed themselves up when it comes to gamers and most their cards endup in mining rigs due to insufficient supply.

The 1060 is memory bandwidth limited based on recent review investigating it, but, you can OC the VRAM high usually. 4xx isn't VRAM speed sensitive. The 1060 is sort of an inferior card hardware wise, yet, it is often faster... that 2GHz+ clock is all it's about with Pascal.

I am using RX460. Once I turn off the "xbox app" DVR, then desktop becomes black/blank screen after playing CSGO. People suggest to do this to fix the fps limit to 30 problem. Once I turn on the DVR again, then no problem. It seem like this is RX460 setting problem. Any idea how to solve it?

Other people have reported similar problems at idle. I'm not sure if it's instability at p0 core or p0 mem controller. Power State 0 is 300mhz 800mv for core. Same settings for memory 300mhz 800mv. You can try wattmon 0.3 or .0.4. It's not yet ready for prime time, but it does provide an easy way to do a voltage offset. doing a 6.25 mv i2p offset would raise the p0 core to 806.25mv on p0 VDDC. I don't know if anyone has tested it with the 460 so it's not without it's risks.

Here's an alternative. Again, I don't know what VRM controller is on the 460 so I don't know if this will kill your card or not. This may be risky but if your thinking of RMAing your card this could provide a faster solution.

Here's a screenshot of my rx480 overclock settings. On the i2p monitoring box, note how the idle vddc is 900+ at 300mhz idle. the 800mv VID is the actual setting.. The offset does not get applied to p0 mem. If that's the problem, I have no solution for you.

I have not done any overclocking..just everything default...

One other person was getting the same thing and had narrowed it down to his stock voltages on p0. He was on stock too. We can't directly edit p0 settings but we can fudge them. Not sure if that's what's wrong with your card. Just my 2 cents. it may be the ramp down to p0 needs a bit of a bump at p1 or p2. If this fixes it, you may need to rma your card anyway. you should be able to do stock settings.

I can't find the posts from the other user. I think it was in the BIOS mod thread but I can't remember. He was getting blank screens after several hours of idle speeds web browsing even with stock settings. Slightly different from your problem. I'm not suggesting you overclock your card. Just, this is the only way I know of to bump the voltage on p0.

edit: My suggestion. try an offset of 6.25 mvolts. subtract 6 mv from p7,p6,p5 so you don't hit your power limit any sooner and see if the issue goes away. If the issue goes away your card wasn't handling stock volts and your gpu needed a bump at one of the lower p states. In that case either live with the fix or rma the card. If it doesn't fix it. consider other software solutions such as uninstalling the driver. running DDU and reinstalling the driver.

Thanks for the detailed reply!

How about 1060 3GB the zotac mini version? That's in my price range.
Otherwise I think I need to shell out more for the 6 GB version. The thing is I don't want to invest too much on this old rig, lol.
