ASIC is just your leakage value it has no actual effect on your ability to overclock besides how high you can push voltage. Overclocking is 100% lottery and unless you're in specific overclocking situations (LN2) your ASIC doesn't matter. Just because you have a high ASIC that might respond a bit better to voltage (not needing to push as far) doesn't mean you'll hit higher clocks. Every chip is unique and will respond differently you just gotta hope you win.

I understand this. I just liked that the stock voltage was soo low and how it undervolted like a boss. I've seen many occasions where a 60ish ASIC will overclock better than a 90ish. I've also heard that with AMD lower ASIC is "better" than higher, that it is backwards compared to Nvidia. No idea if this is true though.

Depends on the cooling you're using and how much you're looking to push it. High leakages use lower voltage but pull more current, low uses higher voltage but less current. On LN2 high would be more desirable as it responds better to voltage but on air lower theoretically is better. Don't worry about ASIC, you could have a low one that undervolts just as well. It all really comes down to chance. My 74% 270x could hit 1350mhz @ 1.3v on air, most barely get 1200mhz

Right.

I'm still debating on if I want to take another chance on a Strix RX 480. Right now I'm using my XFX GTR Black Edition. It does decent. I can do 1350 at 1100mv. 1400 at 1175. Highest I have gotten it is 1440 with the voltage maxed out in MSI Afterburner. I'm really seeing how bad my RX 480 scales with power. Jayz2cents did a review of the XFX GTR. It appeared to me that he hit 1475 at 1175mv. What, they send him a golden ultra binned sample or what?

I'll be honest, I haven't been all that impressed with the RX 480. I'm so tempted to give a GTX 1060 a shot instead.

This One:

Off Subject:
The only problem with this is my monitor. I have a LG29UM68-P 29" 2560x1080 IPS 75hz FreeSync(40-75hz) Display. I have it overclocked to 80hz with the FreeSync range increased to 32-80hz. This is my second ultrawide monitor. My first was a LG25UM65-P. I just can't go back to a regular 16:9 monitor now. I tried a 24" 144hz FreeSync display after my 25" UW and not only did I miss the ultra wide format, I realized that I cant go from an IPS to a TN. So I returned it and picked up the 29UM68-P. I love this monitor! By far the best I have owned. That said, I can't see spending $1000 on a G-Sync Ultrawide to achieve what I already essentially am.

So if I go to a 1060 now I would be sacrificing FreeSync and tearing is ultra noticeable on Ultra Wides. I guess I am overthinking this though. I set my FPS cap to 75 anyways. The RX 480 has been more than capable of pushing 75FPS in all of my games thus far.

I have the worse luck with cards, seriously. My 390 was a dud and could'nt clock worth a dam. This new 480 is the same way. Can't get a little overclock without getting a black screen or a video crash rolleyes.gif

That's because you bought the Red Devil. It has the worst PCB in terms of power delivery of all AIBs, and yes, also worse than reference.

I didn't buy the Red Devil, it was an RMA replacement from a defective 390 I had. After searching around and reading reviews, I have to agree with you sadsmiley.gif

Basically;

Best PCB: Asus Strix -> Power delivery is better than any other brand. Choose this if planning to OC on water, since its cooler is not great. With water you'll replace the cooler anyway. LN2 viable.
No nonsense: MSI Gaming -> PCB is high quality, good for water OC, good air cooler. No other particular outstanding features, just basics that work
No nonsense 2: AMD Reference -> Basically same as MSI, except its stock cooler sucks.
Best balance: XFX GTR -> Easiest for volt modding, can OC both on water and on air, stock cooler is good, has BIOS switch.
Most features: Sapphire Nitro -> If you like RGB , basic OC-ing, bios switch, looks
Hottest card: Gigabyte G1 -> Hot as in temperature, not hot as in trending. VRMs are too close to each other... Only buy for OC if in cold climates or don't.
Worst for OC: PowerColor Red Devil -> Weakest VRMs of all. If any OC is in mind, don't buy. Only use for stock.

Well I tried again and managed to get 1345 on the core and 2200 on the mem with +5 on power limit and no voltage increase.

1350 core= black screen
2250 mem = black screen/screen lock
Increased voltage = negative results

Temps under heavy load don't go pass 65c with aggressive fan curve set.
Using Trixx.

Guess this is the best this card will do sadsmiley.gif

That's not terrible, you should get some decent performance out of those clocks. 1400mhz is nice but you're not losing that much performance @ 1345 and your memory clocked decently
