Yeah, 192bit buses aren't inherently bad, it's just that the 550ti had half of the VRAM chips hooked up to 2/3s of the memory bus while the other half had to work in clamshell mode with only 64bits, if I remember correctly.

Don Lapre posted:I think the recommendation for dk2 is a 780 or better. I'd agree, it's only 1080p but DK2 runs natively at 75hz so that requires 25 percent more performance than 60hz. Plus frame drops are a lot more jarring with VR so overkill makes sense here.

And while Radeon Pro does offer Dynamic V-sync Control, its development has also been halted. With nVidia, adaptive VSync is a regular driver feature not dependent on third-party efforts.

Alereon posted:Starting with the GTX 550 Ti nVidia has also had a few cards that used 192-bit memory buses but with even power-of-two VRAM, which resulted in 25% of the RAM being wasted. On a 1024MB card for example, you'd have 768MB accessible over the 192-bit bus, but 256MB that was only reachable via one 64-bit bus, making it essentially useless. If a game actually tries to access data in this memory performance tanks nearly as badly as if it wasn't there. As I recall they eventually released drivers that kept data out of this region to fix weird stuttering and other issues. I think I'm going to need a citation for that, as it is true that one memory bank has extra memory and lower bandwidth, in GTX 660Ti and 660 reviews there have not been any mentions of significant slowdown after going over 1.5 GB usage. Funnily though most memory usage I've seen my card is pretty much around 1.5 GB so I can't confirm as I don't think I have a game that would definitely use 2 GB of VRAM. Edit: Using Crysis 2 with MaldoHD texturepack memory usage reported by GPU-Z and Afterburner is 1529 MB maximum. I still have no stuttering or slowdown even if I increase resolution past my normal resolution and memory usage does not increase so it might be that the 2 GB is usable but it's not visible to monitoring tools. If there is some free benchmark that is guaranteed to use 2 GB VRAM, I could give it a run. Alereon posted:On the GTX 760 they do it right and pair them with 1.5GB/3GB of VRAM, rather than trying to cram 1/2GB on there somehow, this should work without any complication. I was going to say that the 760 has 256-bit memory bus but they've also introduced 192-bit version as well. Rosoboronexport fucked around with this message at 19:07 on Jun 2, 2014 |

For what its worth I used about 2gb with a 660ti before pretty consistently. There was definitely a threshold you can cross with it that it coudlnt deal with but it definitely wasn't passing 1.5 gb

Seems like they will have to have a separate design for each PCB. Since my MSI 780ti has a midplate that is separate from the heatsink the NZXT might still be the better option for me, or at least equivalent. I'm not sure if I should go all out with the AIO or not. One things for sure, it's time to throw out the Antec 300.

Elaborate coolers you say?  Hoping that I'll be able to reuse or at least mod my Accelero XP cooler for use on a 280X since I'm considering jumping on one soon to replace my 6970. Can't believe this PC is 3 years old now since the 2600K sure as hell doesn't feel like it.. Seems like most of the available coolers are pretty quiet though so I might try one out stock and see how it goes first since it looks like I won't have to deal with the lovely blower-style coolers anymore. I don't know if they'll come close to my current nigh-silent cooler but as long as there's no loud ramp-up at load I can probably deal with it. The MSI Twin Frozr 280X's look pretty nice but I think I read some bad things about MSI cards so I'll have to look into it I guess.

Noise isn't really a concern of mine. I just think that they're hacked on and the form factor(slot in cards) really isn't optimal for the TDPs high end GPUs put out.

eBay mining card trip report: A buddy of mine just got one of those previously-used-for-cryptocoin-mining 280X video cards linked earlier in the thread. It works fine and isn't melted! However, it smelled of burning and literally had soot deposits on it. I guess some other nearby cards in the datacenter didn't survive the mining torture test.

I got a 280x from that fdcservers guy on ebay that is supposedly brand new. It looks the part, I didn't see any dust on it and it came with the little plastic caps that cover up ports on the back and the cross fire connector. I am most pleased so far.

Almost considered getting another 69*0 for crossfire instead since they're so cheap, but I don't really want to bother with the extra power usage & heat. I still find myself surprised when I come across listings that claim they picked up the cards within the last 3 months or so - You'd think by that point even the most delusional miners might have seen the writing on the wall. future ghost fucked around with this message at 19:32 on Jun 3, 2014 |

Combat Pretzel posted:How does running 24/7 for weeks under full load in an overheating rig affect longevity of the cards? It reduces the life span of many of the components, such as mosfets and capacitors. The key word there is "overheating" though. If it's cool enough chances are really high that its fine.
