Reference cards are better overclockers ???

I berate people who buy Matrixes because they believe the marketing and say its better than reference cards. (Spreading wrong info, again; May not be true for LN2)

As I said before, I bought the Matrix with the intention of doing my first LN2 session once I finish moving country and setup my new apartment, You need to stop assuming you know what people are going to do just because you would do something different.
 
Make up your mind, is it against the reference cards or all cards?
And you wonder why people call you arrogant, sheesh.

I dont wonder at all, i enjoy it until someone puts me down or proves me otherwise; then ill sit the frack down. Yet to be done though, i do help people if they want to listen.

The way you go about helping people is wrong though, If you want to teach people you shouldn't insult them for making a decision different to yours.
 
Not really. Ref cards ASIC is between 60%-85%. Below 60% they used them for 290 thats why some 290 could unlocked them to a 290x.Then asus ,msi and evga sometimes bin chips based on the ASIC quality (60-75% is the best for ln2,watercool).IN reality the really high asic quality are the hottest one but they use the lower volts. 7990 chips were 85%+ asic quality and they used really low stock voltage.In general you see low ASIC chips to the custom cards

It's way too often that people think that a high ASIC % means "high quality". This is actually the opposite though. It denotes the leakage of the ASIC (GPU core) and ties in with TBP (total board power) or TDP (thermal design power). Graphics cards are designed to run with a specific power consumption and thermal output in mind. Higher ASIC % = higher leakage = higher power consumption = lower default voltage to keep temperatures/power consumption down within safe limits. Lower ASIC % = lower leakage = lower power consumption = higher default voltage, because the manufacturers want a consistent power consumption and thermal output.

If you run an 85% ASIC video card at the same voltage as the default voltage of a 65% ASIC video card of the same make and model, and run it in furmark with unlocked/maxxed out powertune, you will find that the 85% ASIC video card will likely have temperatures spiral out of control. Also, because of the increased power consumption, you will stress out the VRMs much more, especially in overclocking.

Typically, you will want the lowest ASIC % cards you can find. They will have a much larger headroom as far as power consumption goes, and will typically use less power and have lower temperatures compared to a high ASIC % card. As far as stable max overclock speeds, this is still a hit/miss situation.
 
Generally high end custom PCBs destroy ref cards.

Top 7970? Lightning
Top 680? Lightning
Top 780/ti? Classified
Top 290x? Lightning

Stronger components, more power phases, more efficient, be it under air water or ln2. Yes you still play the silicon lottery, but it greatly improves your chances of a decent clocker, as in most cases lightning's/classifieds/soc/glh are binned, in the kpe's case binned very stringently.
