hvalentino · May 2016

they still have a bunch!! and is worth it!! I'm getting 5 more lol

Heliox · May 2016

Yeah, would love to get me some more ref cards, best cards i've got. Running 24/7 for more than 2 years now. And under some serious stress as well!

Congrats!

I need help to do that... do you know how to do it with Ethos?

SIRacer09 · May 2016

Nope, sorry. I'm on Windows.

hvalentino · May 2016

@SIRacer09 No worries

thanks!

hmm. that seems low for 4x r9 290. my HIS IceQ brand 290 is getting 28mh/s and up to 30 if I overclock it, but then it wavers on stability.

r9 390s commonly get 30mh/s or slightly more.

Mine is R9 290

and is worth it!! worth the buck!! oh and I didn't do any overclock, is out of the box setup

hvalentino · May 2016

@shutfu what power supply that you used btw? and how many cards?

Heliox · May 2016

@hvalentino

If you check what type of memory your reference cards have (Elpida, hynix or samsung) i can make you some roms(bios) with an undervolt or overvolt as you prefer. With a higher or lower core clock, same for memory.

As well as tighter timings.

Your cards will perform better and will (in case of an undervolt) stay cooler and will use less power.

Greetings!

hvalentino · May 2016

@Heliox hmmmmm how can I do that?

SIRacer09 · May 2016

@hvalentino I think GPU-Z will give you that info..

shutfu · May 2016

@hvalentino i bought a 1275w platinum thermaltake off craigslist (was still in shrinkwrap though), but i honestly cant recommend it because the 12v is split into 2 rails and they only give you cables to use one of the rails for video cards, so once i add another card, i;m going to have to buy some molex->6pin->8pin adapters to make use of the other rail. Pretty stupid.

big_MIKE · May 2016

Evga's all the way baby. Single rails, run great, and come with 24 pin testing adaptor if needed for two psu rig.

Is this possible to do with 390s?

Heliox · May 2016

@bctopics , working on that :-)

Awesome, When you do let me know!

Ikeago · May 2016

Congrats I love those cards. Here is some random info I have ran across while using them. There are some older bios for those cards if you dig back through the litecoin on bitcoin talk. Right now I am getting right at 29-30mhash per card running them with the stock. Mine have been around since litecoin days so I replaced all the thermal pads and paste on them and they run a lot cooler.

Just FYI I am running a few of those cards and they are awesome but they run hot. You might want to consider replacing the fans on them if you are running them somewhere that it gets pretty hot.

A while back I wanted to see if A/C was even going to be a possibility so I put 25 of them in a room with a 12000 BTU A/C unit. The night was cool probably 50F outside. Next morning it was 120F in that room. The A/C was not even coming close to keeping up.

hvalentino · May 2016

@Ikeago wow 29-30 thats awesome! what OS that you use? and you mentioned that its stock so you didn't do any overclock or undervolt stuff right?

Heliox · May 2016

If it are the roms The Stilt made (i guess they are) 2 years ago, they do not run 30Mh/s Eth @ stock clocks (which is 945). (at least not over here) My 390x barely does that

.

At stock clocks "945" they do around 27,5 ish..

Just checked mine
30.5 Mh/s at core clock 1050, memclock 1125 -- 290 non x
31 Mh/s at core clock 1050, memclock 1125 -- 290x

-50mV Core, -75mV VDDCI/AUX for both.

But those are my numbers. I could be wrong and maybe he does hit 30Mh at stock clocks.
If so, i would like to know some more details

What rom exactly, driver version, os..

Greetings.

hvalentino · May 2016

@Heliox I might try to overclock it but i need to get watt meter first. consider that I can't undervolt with Ethos..

SIRacer09 · May 2016

Just picked one up as well. Got it from Newegg. Just looked this morning and they are sold out. @hvalentino must have bought most of them!

Running Windows 7, going to install it tonight. @Heliox do you have any roms for these? I'll be running these as long as possible, so any undervolting, etc would be great! Thanks!

hvalentino · May 2016

@SIRacer09 hahaah damn bro.... Im about to grab another one... there goes my card lol

Heliox · May 2016

@SIRacer09

I've got a package for 290's with Hynix mem, still have to do the Elpida ones

Check gpu-z what kind of memory you have. If you can respond within the hour i'll be able to send em to you. (After that i'm off on holiday

)

Greetings

SIRacer09 · May 2016

@Heliox Is there a way to tell by physically looking at the card? The card hasn't been installed yet.

Heliox · May 2016

@SIRacer09
Mmm good question. Not that i know of.

Maybe, if you're very lucky.
You could check techpowerup.
https://www.techpowerup.com/vgabios/

But i doubt it's going to clear things out as the cards you find there mostly just show all the compatible types of memory. So i fear it isn't going to help..

SIRacer09 · May 2016

@Heliox
No problem! I'll install it tonight, look in GPU-Z and update the thread. I wonder if I could gain anything from my 7950s and R9 280x undervolting... Half are Hynix and half are Elpida

Howdy, Stranger!
