Radeon RX 480 "Polaris" Launched at $199

The fact of the matter is anyone who overclocks a PCIe only card such as the 750TI will go over the 75 Watt mark.

Infact according to the slides of the authors of this whole thing (Toms Hardware) the 750TI they tested at stock runs at way over 75 Watts for 90% of the time.

Oh well guess we will see lots of damaged motherboards after reports filled on AMD forum.

Ok, either I'm missing something, or this 'damaged motherboard' report deserves the 'troll of the year' award:

"so at first I thought the card was dead and I put back in my 750 ti"

...yet humbug just posted a graph saying the 750ti runs at over 75W for 90% of the time?

EDIT: The report mentions that it's using an "ASRock 970 Extreme4" motherboard. It'd be fun to go on reddit and ask if anyone using a reference RX 480 on this motherboard. See if they had problems...

Components will be rated for much higher burst loads over sustained loads. With heat and maximum delivery average is more important so at stock the 750ti won't cause a 75w slot any issue. Obviously if you overclock it then it would run it out of spec.

It wasn't a reference RX 480 after he jacked it up to 1350MHz (which very few people will have done) before ragging it for 7h of gaming (which quite a few people will have done).

A large number of cards have been sold, invariably there will be problems with some combination of users, hardware and fiddling. Would be hard to dish out blame with real certainty on small samples.

I'll be sure to hit the forums before customer support if anything interesting happens to my stock 480 4gb on my 2009 Maximus Gene III mobo.

Alright, I've bitten. I really want to see someone confirm this, so.......

I've actually reached out to that AdoredTV guy and offered to sponsor a test! I'll pay for an ASRock 970 Extreme4 if he's willing to put his RX 480 on it and play Wither 3 for 10 hours straight!

I'll extend the offer here on OCUK forums.

Gregster, are you up for it?

Gibbo, any chance you guys can bring in this model? I can only find the older one: https://www.overclockers.co.uk/asro...ocket-am3-ddr3-atx-motherboard-mb-068-ak.html

Never saw you jumping to post news when nvidia drivers were killing peoples machines. Or fermi cards burning out? nvidia shield being recalled due to potential fire hazard. All ive seen you do in this thread is literally look for every ounce of negative news and post it no matter how miniscule it is.

You a try hard troll or something?

Don't forget the overclock to 1350MHz.

Which if TTL is to be believed does nothing useful whatsoever.

Theory is that AMD got as much performance as possible within the cooling/noise limit and set the power limit to match.

Until someone throws money at bumping up both the power and the cooling it seems overclocking is pointless.

It wast cooling that was the limiting factor if you watched TTL video. He threw fans at 100% and did nothing to the score. It was just literally power throttled. He even explained what that meant.
 
Looks like he's spilled something on his motherboard around the second pcie slot, either that or he's let it get really grimy..

Overclocking it to 1350mhz is going to put him well above the spec, so in all honesty, knowing it can get close or slightly exceed in extreem circumstances the pcie spec @ stock, he may have killed it that way.. And yes, the cards are definitely power limited.

Overclocking have always void your warranty.
Most users forget that its on your own risk.

Its why two things are key, a good psu and motherboard.
The power delivery is the main thing you never in any case want to cheap out with. I have a 750w psu on a single card and its a quality one since years back.

If your going to OC always make sure you have a margin of error.
 
I don't mind admitting that this power draw has me a little concerned. I have just built a brand new system which I would rather not have to strip down. Not sure I even want to try overclocking after seeing what PCPER had to say.

So overclocking on the reference board is a big no no then?
