When I got the black screen I was using stock voltage w/ core clocks of 1100Mhz (memory is at 1500Mhz of course).


I will further test it later at 1500mhz at +50mV see if I get any black screens w/ a bump on core votlage.

Awesome, thanks for the info. Mine won't even open chrome at 1500 memory and stock voltage. Maybe I should try the triX too...

On the topic of the tri-X bios, according to this: http://www.techpowerup.com/vgabios/151536/sapphire-r9290x-4096-131212.html it has Elpida memory capability too.

Honestly though, and someone with good bios knowledge please answer this, is there any difference between bios' and manufactures for reference design cards? If no, my guess is the tri-X bios is identical to reference except slightly OC'ed (since it uses a reference design card).

Stilt over at bitcointalk litecointalk forum has been modifying bios's for miners there. He found that some bios was inefficient in regards to how it handles memory and VRM's. His modifications not only improved hashing rates, but lowered VRM temps in a lot of cases.

His threads have recently locked up though and he's no longer taking pm's for some reason.

But yeah... there are differences between the bios of each card even from the same line.

Awesome, +rep.

I took a look over there a few times, I didn't know he released anything.

This was the 280X thread: https://litecointalk.org/index.php?topic=12369.0

There was no blanket bios for all cards. People uploaded their vanilla bios, he reviewed it, if terrible, he modified and gave it.

I'm looking into getting a ref. r9 290, atm i'm choosing between the gigabyte and the sapphire, is there a higher chance of getting hynix memory with either of the brands or does it just depend on the batch?

Probably depends on the batch.

I generally have vsync on for the most part so my hardware isn't doing more work and producing extra heat that isn't needed, though during winter I don't exactly care and may turn it off, though games like TF2 (or any source-based for that matter) I let run at 120-300 FPS as the input polling suffers horribly with vsync on.

I turn V-sync on with my 290 mostly to get the fan to slow down a little bit, and cut down on heat and power consumption. Mind you, with v-sync off in BF4, it only drops from 75 FPS to 60 FPS on high, so there's not a huge drop in FPS.
