Nice. Looks like it works well.

Seems to line up perfectly, from what I can see anyway. Possible to use bolts do you think?

Or are the holes slightly offset from each other?

I buy the bolts, because the maelstrom have thread in the block countersunk i was sure like you are the same but, are extreme similar, like a 99% but in the final part when you screw start to see a little diagonal thats because the zip ties works fine, because the difference its really minimal, i can tell you if the bolt was "flexible" will work jaja
The secret was use 2.5mm thickness zip ties, the zip of 1.5mm don't have force and you have movement, with the 2.5mm the "Jump" between clicks of the zip ties are more longer and when you go to the final, its increible tight.-
I have no more than 50º with 1430 mhz, and 1.25/27 volts in GPU - Was very impresive about, the VRM you must put a fan slow fan but put one to avoid over temp.-

I gotcha.

Great explanation actually, that's exactly what I wanted to know. Definitely will be cooling the VRM's too.

Thanks man!

Thanks to you to ask, by the way - I use the same PWM connector of the GPU to control de FAN of the Maelstrom, I buy the adaptator of "Mini PWM" you know the connector of the video cards to a male PWM connector (i call it PWM because have 4 pins jaja) - And thats the most effective way and in that case you can control using custom curves of temp based in your temp

That's a useful cable right there. Thanks for the tip. I should order a couple of those and have them in case I need them.

I don't see the mini 4pin PWM connectors going away any time soon on GPU'S.

Thanks again bro.

I do some benchmarks and logs this my final stable overclock in all platforms was 1430 Mhz for the core, 2250 Mhz for mems - 1.26 volts for the GPU, Memory stock voltage - I get the information with GPUZ and HWiNFO 64 - Im not a professional reviewer so this information its not a gold value.-

Personal I use unigine to get some overclock stability, then go to metro last light for artifacs if i not find anyone in unigine, then go to combined test of Fire Strike, if all pass for real stability play Battlefield 4 that **** crash very easy if you have something wrong usually voltage.-
Something to pay attention its this, if you are going tu use Asus GPU Tweak II there is a bug, or may be its a Vdrop I have unlocked bios so its not the bios, you put a value and in the practice its more lower, so use GPUZ to check in load wich its your real value, and make the adjust in the software.-
In theory im using 1.343 volts but in the practice its 1.26v



About the VRM Temps was 100º the max i can ever get, usually its between 90/95º the max operative its 125º - so its safe.-
The core temp im using like i say a maelstrom 120k baby-water with a custom fan curve, its a cheaper water but very good performance 69º was the max temp i get, Metro Last light its the game who rise more high temps don't know why really so if you want to check temps do it with that game.-

About Furmark, forget it, rise to much power draw and its going to blow your motherboard or VRM, just use all this another tools, are more similar to the real world.-

Im waiting the another Maelstrom 120K to put it in the Second RX 480 and make test in crossfire.-

Im trying to create a 100% stable voltage/frequency curve at this point.

Got memory to 1950 with 1.100v.

Current F/V curve looks like this...

525/0.818 : 0825/0.850 : 1120/0.950 : 1180/1.000 : 1250/1.025 : 1300/1.070 : 1330/1.120

Still likely have lots of room left for dropping voltage at specific frequencies, the above seems 100% stable so far though.

Keep in mind the wattage reported might be a lot lower than actual wattage.

My 480s pull about 150W each from the PSU, but GPU-Z reports 110W and HWinfo reports 90W. I don't think either program measures the power used by memory.

The 200W you see might actually be 300W from the PSU, so be careful with the voltage.

The power draw with an actual 4gb card is likely lower than an 8gb based card. Dont have the equipment on hand to test at the wall though. redface.gif

The RX 470 maxes out at 180w on the GPU circuit without doing power limit workarounds. AFAIK, the RX 480 tops out at 225. Im likely seeing ~200w at the PSU for total board power. GPU VRM input is hitting ~150w and output is ~120w.

IMHO the RX 470 fits nicely at the $200 price point if the gimped RX 480 4gb didnt exist. It works well as a 6 pin card at stock too. The RX 480 should have been 8gb only, 8 pin (2 slot/4 aux VRM split), with a slightly improved cooler (more densely packed fins perhaps) @ $239. The product stack would not be as broken if that had happened.

@GecKoTDF

You have similar temps to my card and I'm on full cover. I might be 10 to 15 degrees cooler on average is all. for example fallout 4 is mid thirties to 40s (if I close the door to my office) , but firestrike ultra sress loop goes into the 50s to 60s depending on if I have the door shut to my office. Valley is in the 50s after a few runs. Very nice mod considering I have three rads in my loop and a d5 and you're not that far off with higher voltage but lower frequency. My VRMs are much cooler but that's too be expected. I don't have the best TIM application but it's not worth fixing. It's quiet and cooling isn't what limits my oc so what more could I want?

@KarathKasun

The only benchmark I've seen where the video memory plays a bigger role than I'd expect was Rise of the Tomb raider. However, the new driver version doesn't seem to be as video memory dependent on that bench. a 10.5% memory clock rise gives me a 2 or 3 percent increase in fps. I wasn't getting consistent performance before and geothermal valley had texture pop ins on the old drive. I seem to remember a higher video memory performance benefit in dx12 very high preset with hbao+. The rx470 launch driver seems to have fixed that. You see any memory bandwidth performance issues with the rx470?
post #460 of 4151
Going from 1750 to 1900 (8.6%) takes my score in Valley from ~3200 to ~3500 (9.4%). A fairly linear increase with these settings... 1920x1080, ultra, no AA.

My only memory problem seems to be heat "soak". After the whole board warms up for 30m or so I have to back off on my memory overclocks. IE 1950 @ 1.1v has to be pushed down to 1900. 1900 @ 1.0v has to go down to 1850.
