So I chose a 74% and 72%card for my crossfire setup because they ran much colder which is important in crossfire on a matx motherboard. I didn't play around with all my cards but one of the highest one was a 93% ASIC card which ran super hot compared to the others.

heaven and valley don't mind my higher memory clocks. 3dmark gets controller vdroop as it ramps up and down and throws errors still.

I did some runs with my CPU at 5.1GHz and oddly I received slightly lower scores. Higher min fps on valley but lower max. Not sure what's up with that. CPU is only bench stable at 5.1 so maybe its that. I'll go back to 5.0. It's everything but prime95 small stable there. Aida64 extreme fpu has it at like 80 degree max there.

"ECC" is supported on all GDDR5. It's just not comparable to traditional ECC on DRAM.

Remember "ECC" means "Error Correction Checking". Even though the GDDR5 ECC isn't as thorough as ECC DRAM it's still considered ECC.

Thanks. So does it do some sort of hashing checksum or does it have extra parity bits? (Earlier in the thread it was suggested it uses a hashing checksum.)

I am not sure on either. I wouldn't think Parity Bits....

Hash checksum would get my vote.

ASIC score is % leakage. Lower is actually better as explained https://www.reddit.com/r/Amd/comments/4rzo88/the_stilt_explains_asic_quality_on_amd_cards/

That is explained directly in GPU-Z when you check the ASIC quality. 

 

It states higher overclocking capabilities for H2O/LN2 with lower ASIC as well as other attributes:

Thanks the redit was a good read.

GecKoTDF a lower asic score should be able to clock higher then but have a hotter card if I read that correctly?

Thats right, well but something here not say, its... you have more power draw, so you need more voltage, thats the reason because you have more hot, yes, you can get better clocks. The lower the ASIC quality is, the higher the voltage leakage is, which results in better voltage response thus better overclocks - But you have more hot.-
Thats because its more suceptible to water cooling, because with a good control of temp (only the water can give you) improve a lot.-

Thats because i need 1.26 volts tu get 1430/1440 mhz, if i have the way to control the temp probably can get 1480/1490 mhz without problem

Hey guys. I've been told from a poster here that the MSI RX 480 Gaming X is using 4+2 vrm and i was a bit worried but then i found that i missed the pictures of the vrm on this review

http://www.overclockers.com/msi-rx-480-gaming-x-8g-video-card-review/

it is visible that they are actually 6+2 am i wrong or i don't understand what is going on here?
