RX 470 stock clock woes :(

[implosiveturnip]

Similar setup here, I have it in the silverstone sugo sg13, with an i5 4460. I was considering using zip-ties to mount the CM seidon AIO that's on the CPU to the GPU instead, but the bracket is fiddly af and tbh I really CBA taking it apart (again) just to do that. Plus the crappy CPU cooler I'd have to use would likely be louder than the GPU's blower.

Set the Power Limit to +50% via Wattman/MSI Afterburner, and the clocks will not fluctuate unless you exceed the maximum temperature listed in Wattman. If you exceed the maximum temperature, increase the fan speed a little.

Is that in WattMan?



Why do I have to go to these lengths to get a card to work as it's advertised though? It's pretty poor form tbh, and I'm pretty sure it constitutes false advertising. I imagine the less tech-enthusiastic would be well put off by having to do this.

I'll do as you suggest when I get home this evening, but is there a Sapphire rep you could pass this on to? It's really not on, misleading consumers like that. (*EDIT: That's assuming all these cards experience the same issues, which from the post by Karik666, and your own reply, they do).

Right, well better late than never I suppose, finally got around to tweaking this tonight, have settled on the following thus far:

core: 1250 @ 0.95v
mems: stock @ 0.965
pwr target: +50
temp target: 81
fan stock/auto

Quite happy tbh, been running valley for a while now, temps have peaked and fan is living-room friendly thank god!

I know I can push the mem up a little, but saw a post on Reddit about a week ago that showed pushing the memory on the 470 (and 480 I think) actually gave worse performance, as the latency increases to allow the higher freqs. At the time I had my memory at 1825, so I fired up Valley and did a run with the oc, then a run with the memory at stock. Lo and behold, my stock clocked memory run was just under 60 points in front.

Now I only did this once, so not exactly totally undeniable results, still, interesting. And keeping the memory at stock I've been able to drop the volts a little. Still think I can get the memory lower, though if I take the core much further down I have to drop frequency to keep it stable. Pretty happy with the 1250 tbh, not exactly a groundbreaking OC, I managed to keep my original OC with a decent undervolt. Tempted to by an aftermarket cooler or a thermosphere just to see what I can get out of it now though

Here's that post about the memory in case anyone wanted a read:

All sorted?

On some GPUs you have to increase the power limit to +50% to avoid any sort of clock throttling.

For me, yes. I don't mind messing around with these things, but I still stand by my previous statement that you shouldn't have to go to such lengths to get the card to work properly. Can be especially off-putting to newcomers to PC gaming.

Set him to 50%?!? Good luck with that.

Whats the link? I can't view it at work

If it's worrying about power draw, as I suspect, after a few hours on gta V last night, power usage (as measured by afterburner) never went over 100w, and if I had v-sync on, it would hover around 80-85w. So I'm not all that concerned.

You can use the Polaris bios editor to make the tighter timings run at frequencies upwards of 2000mhz. It's really easy to do. Iv done it on my mining card and it gives a really big boost in that.
Just stick to 1750 or 1500 straps and don't push it any harder than a stock 480 would go and its fine.

Nice one, I've just grabbed it from OCN, might give it a bash. Anything I should know with regards to memory voltages?

To be honest this is pathetic and doesn't make me feel warmer towards AMD at all.

They're basically saying that all they have really is one card but here's more variants where we screwed up the numbers so bad that you won't get decent performance out of them unless you know what you're doing. Like before, hey we can't make more than one type of card so we'll hide 4 gb away hoping no one realises how we tried to screw them. Really poor show.

Makes me wonder how many people run these cards and don't have the knowledge to sort it out for themselves.
