Re: Custom RAM Timings for GPU's with GDDR5 - DOWNLOAD LINKS - UPDATED
Same as mine that goes up to 2300...but to go that high, cooling should be made
in such way that metal plate covers not only GPU, but memory, too (and replacing
usually bad factory thermal paste with quality one)
However, 2100 should be easy to achieve
Also, important is to find sweet spot between voltage and temperature (voltage increase
improves stability, but only up to the point where increased heat starts to be a problem)
About the memory strap: The board came to me with Matthev timing. I tried many timings (heavyarms, yours, some for anorak's) and the original one (matthev) was best (at least at 1900~2000 clocks). I did some changes/tests and for now I have it:
777000000000000022CC1C00CE615C41C0571016B30CD50900400700140514207A8900A00300000 010122F3F9D2C3617
Is there a way to improve "performance per clock" for Cryptonight? (considering that it couldn't run at 2000+)
0.5 mm or 1 mm and a copper shim, 1 mm thick or more https://www.aliexpress.com/item/20-pcs-15mmx15mm-0-3mm-0-4mm-0-5mm-0-6mm-0-8mm-1mm-Heatsink-Copper/32826278552.html?spm=a2g0s.9042311.0.0.3dbd4c4dpaqYyI
I experiment with the thicknesses so that the stock heatsink presses the shim and the pad slightly without being thicker than the processor height (been there done that, and the GPU fan was squealing
) the more spacious the copper shims the better, however, i do this on rough estimates, that the memory die consumes 1-2 watts each (reasonable?) the shims not touching the aluminum directly is not a big problem, because copper blown by the gpu fan imho is more than sufficient to cool the memory. Most of the Aorus 580s i have memory cooled from the factory reach 2100-2200mhz (8 gb, 4gb all of them hynix) i found thermal pads being 0.5 mm and perfectly matched with the heatsink, but, as a consequence of mining these pads will dry within months (become brittle)Do you really clock those elpidas to these clocks? lol? how do you cool them? what sort of timings for such clocks!?
