Determine Hynix/Elpida Memory on 290x cards based on Product Number before buying them! (Confirmation needed, please help if you have a 290x) - Page 3

post #21 of 60
I'll post some details, for the sake of giving some advice!

- Name of the card: Sapphire Radeon R9 290X Battlefield 4 Edition, 4GB GDDR5, 2x DVI, HDMI, DisplayPort, full retail (21226-00-53G)
- Hynix/Elpida or Hawaiiinfo output: Memory config: Elpida EDW2032BBBG_DEBUG2
- P/N short one: 102-C67101-00-AT

EDIT: P/N on card is: 102-C67101-00 000001

I'm sorry but what program lets you read the information of the gpu like that?

Whats the heat like and how do you keep it cool?

heat is like 65 C with 100% fan in a regular room. but since it's a rack mountable case, you can colocate it in a colder datacenter.

for all the haters: i posted some proof in the first post about mining/memory speed for the 290x hynix/elpida cards. just try it yourself please, i added a cgminer mining instruction!

I just got my card today and haven't installed it yet. I did take it apart to check the memory tho

 

Name: PowerColor AXR9 290X 4GBD5-MDHG/OC Radeon R9 290X 4GB 512-bit GDDR5 PCI Express 3.0 CrossFireX Support OC Video Card (BF4 Game Bundle)

P/N: 102C6710100 000001

Memory: Hynix

Fact is: 938/1500 gives you 980 on an elpida and 1025/1500 gives you 1000 kh/s and could be clocked even higher. Elpida will give you 700 kh/s with 1025/1500.
It might not be Elpidas fault, the reason for the hashspeeds could be, that the '-00' models are 'golden' as you say and the '-01' are poor. But why is AMD selling poor -01 290x as real 290x?

Show me a Hynix 290X that performs significantly better than an Elpida 290X at the same clocks, on the same OS, and with the same drivers. Then I'll believe you.

we are talking about mining hash rates, not gaming/benchmarks FPS.

Hynix ram gets for much higher HASH RATES. this is fact. why exactly, i dont know. maybe because it can be clocked higher than Elpida, and thus allows more overclocking of the core clock to maintain the "stable" ratio of core to memory clocks hawaii likes. or maybe hynix is less sensitive to the clock ratio, who knows, but it gets moar coins.

i have a sapphire 290x w/ hynix, and will check the serial# later tonight.

Higher clocks = higher performance? Who would have thought?

Is there a real difference clock for clock? If speeds are different, results are meaningless to me.

the real difference is that Elpia won't clock as high as Hynix.

thus CLOCK FOR CLOCK at say 1000/1600 for example Hynix is going to outperform Elpida by an infinite percent because Elpida will just crash.

Troll harder?

My card has Elpida's and can do 1700 stable. I'm not the only one either.

I don't care if Hynix IC's typically clock higher (which there's no evidence that they do). What I very clearly asked was, "What's the difference between them at equal clocks?"

Do you even own a 290? It seems as if you actually know next to nothing about these cards.
