r9 290x

[CoinPN]

So I'm gonna purchase a R9 290x and I was wondering if there is any difference between the sapphire/msi/xfx/msi and gigabyte model for mining?

Thanks.

gigabyte usually works fast without major tuning while sapphire may need oc to reach same khs

[railzand]

don't get xfx, get gigabyte

don't get xfx, get gigabyte

Sapphire Radeon HD 7950 Graphics Card (3GB GDDR5, DVI, HDMI, 2x DVI)
isnt good this GPU for mining LTC?

People told me to get Gigabyte too but I found out it was one of the slowest at mining.

Sapphire is the fastest in my experience. The people giving you advice probably never tried out any other brands, but for the same exact graphics card, Gigabyte gives very poor performance in terms of mining.

I concur with the Sapphire recommendations, both on R9 280x and R9 290.
It isn't that Gigabtye is bad...Sapphire is just better! :-)

Reason? you got to clock the sapphire one more to get as much khash

Saphire is great
the vaphor-x is king trust me
Asus is Very nice the CU II its amazing
Gigabyte sometimes hard to set it good
HIS is prety nice
XFX Run awayyyy

personal opinion.

ASUS Radeon HD 7990 6GB, i headr that this card can run  total 1400kh/s,,is that true?Peoples says it has two cores which run at 700kh/s each core.

[greentea]

have a sapphire 290x running at 880Kh/s

[theomoplatapus]

From what I've seen sapphire is the fastest.  I have the ASUS and get 880 kh/s though.

[bumblebee33]

I have 5 x Sapphire R9 290's and 1 x Sapphire OC 7970 -- I too prefer Sapphire!

Do i need good processor ?do i need much memory ?Is enough like 2 GB for 4 GPUS? Sorry im still noob on litecoins mining hardware

I've got only gigabytes:

r9 280x  ~ 720 kh/s
r9 290   (! without x !) ~ 870 kh/s

Be aware that gigabyte GPUs are voltage locked, so you can't undervolt them directly throught software like trixx, cgminer etc.
However, I undervolted GPU voltage by flashing GPU vBios on r9 280x and instead of 1.2V now runs on 1.075V and it's completly stable.

SAPPHIRE is the best. Veterans say so. Also look for a 7990 if you can get it.


Also try your luck here,

I wouldn't need to undervolt it, if it's electric bill you're talking about, but thanks for the replies

What software did you use to do that? And did you overclock core and memory clock?

[hakeriukasx]

I havent used anything yet,I just wanna start to build mining rig but before buying stuffes im looking for info i dont wanna buy and throw it away,I just asking would be that card useful ?

Not 290x, but I have 3 280x's.   A gigabyte, an Asus, and a Sapphire.  I've tried everything i can to boost the performance, but I think I'm just about maxed.   Anyway, the Sapphire is the fastest of the 3,  running around 730Kh/s.  the gigabyte and Asus both run around 710Kh/s.   Just thought I'd add that the Sapphires are faster
