Is their any major performance differences between two?
Deference between them probably just a couple of degrees. As for whether it's safe to use nickel plated block, yes it's safe. The issue with nickel plated block, if it's not plated properly, it may flakes but it doesn't reduced cooling performance.

Guys, i did lots of research, Hynix on 290/290X offer better oc 8/10 times. The Tri X cards, almost all i saw till now around ~10 cards, reached 1600+ on the memory thumb.gif

Elpida on the other hand, most of the times max out at 1450.

Maybe also the impressive cooler on the Tri X and cooling pads on the memory helps? guess so.

BTW did anyone played with Aux voltage? worth it to use? what exactly does it do?

I dont think the cooling should help much. Mem heatsinks on my card only get warm (and I actually mean hot, im estimating 60-70c) when running a miner. Games they are still cool to the touch. I mean I've attempted to OC my dud Elpida from a cold start and it doesnt help, so I doubt its a temp limit.

And I do think I found higher Aux to help maintain stability with memory OC slightly, but that might be placebo.. I dont use it anymore.


p.s. is it confirmed Tri-X are hynix only? That would be the first card to ever be hynix only, 79XX or R9 290(x)... I think even the Lightning 79XX came with Elpida and Hynix?

From like 10 units i saw by now like i sad, all of them (290/290X) had Hynix, i don't think that's just an coincidence smile.gif

Not sure about 280X/7970? was there 7970 with Tri x? i don't think so...

Well it's a new, simpler memory controller than what the 7970 had, and considering people aren't even getting rated speeds from the memory my guess is that the controller is the issue. Maybe just because of voltage, although I think it runs on core voltage, doesn't it? Because increasing core voltage definitely seems to help with memory overclocks.

Fan speed ?

I dont think so.Maybe powerlimit helps. Either way hynix are rated higher. I have seen elpida maxed out around 1500,hyniix can go more.Jomama has a 1750mem 290x hynix so the controller is fine

Agree, controlelr is fine, Elpida crap is the issue most of the times. Or maybe their timings? anyway, Hynix chips are generally better bins/higher quality same like Samsung ones are usually better then Hynix.

Where did you see that the Hynix are rated higher? All I've ever seen is that they are both 6 GHz.

Someone ought to collect stats, so far it is all anecdotal and I suspect the Hynix/Elpida history colors the conventional wisdom.

Again, how do you know that? The memory controller is completely new and there is very little actual data on which memory is overclocking higher, unless you know of a spreadsheet/database I don't.

If the controller is fine then why can't all the cards hit 1500/6000 at default voltage? Unless the theory is that the RAM is being undervolted, in which case all the data kind of goes out the window anyway.

And just to be clear, I'm not saying the memory controller is bad, or weak, just that it may be the limiting factor when it comes to overclocks, especially considering many people can't even get the rated speed out of the memory.

It's not a WEAK controller. It's a 512bit imc, I'd assume it's rather stressed and we have no voltage control over it. We don't really know what it's potential is yet. Tahiti's imc is 384bit, child's play in comparison. And considering Hawaii's high memory overclocks are in the 1700mhz range (which is not far from 1850mhz for Tahiti) and then add in the fact that there is no voltage control, Hawaii's imc is doing rather well given its circumstances. Also, ya realize the difference in theoretical bandwidth between the two right? Hawaii is a large speed step forward. The actual memory ic speed isn't really a huge point when we realize the speeds are already freakishly high.
