Determine Hynix/Elpida Memory on 290x cards based on Product Number before buying them!...

post #1 of 59
Thread Starter 
I recently ordered 8 x Sapphire BF4 290x cards from different Vendors. Only 3 of them have Hynix Memory and 5 of them have Elpida. (I was told, all Saph. BF4 models have Hynix mem, but the majority was wrong :/ )
What i found out was, that the Hynix cards have Product Numbers in this format:

102-C67-101-00 000001
All three have 00 000001 in the end. S/N vary from Z1349.. to Z1350..

The Elpida cards have P/Ns like
102-C67-101-01 023036

This made me think, that -00 cards come with Hynix and Elpida cards have -01


Could you please help me to confirm this?

You can find out about Hynix/Elpida with Hawaiiinfo12 from here: http://www.overclock.net/t/1445030/is-your-r9-290-unlockable-find-out-here (instructions inside)

If you can't check the bottom of your GPU for the long P/N you could still get the important part of the P/N from your Box or from
Catalyst Control Center in Information->Hardware - BIOS Part Number (ex.: 113-C6710100-102)

Please post your card infos like this:
- 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: 0x500036A9 Hynix
- If accessible: long P/N on the back of your GPU: 102C6710100 000001 and short one: 102-C67101-00-AT
- Otherwise check your CatalystCC for the BIOS Part Number, post only when using retail BIOS: 113-C6710100-102
- Your S/N (optional): Z134900000506
- If you are a miner, post your clocks and scrypt speeds: Best configuration for an Elpida: ~930/1500 = 850-890 kh/s
Best configuration for Hynix: 1025/1500 or even higher: 1000 kh/s
- If you never mined before, check below for an instruction to test your speed

I checked through some BIOS Part Numbers from different manufacturers and found out, that the last P/N part can be:
-00, -01 and -50, -51. The 5# versions indicate uber-mode (bios switch right), the others quiet-mode (switch left/default).
Note: This only works for 290x models! All 290 non x models always have a -00 or -50 ending, even for Elpida.

Update: I benchmarked hashing speeds with elpida and hynix cards and they are both equal! (the benchmarked hashing algos didn't access any memory, they use registers only)
So it HAS to be the memory which is slower when mining scrypt which uses all the memory. Gaming should also be a little bit worse, but scrypt mining is the proof that elpida just sucks for all those who think they are equal. That's not the case for 290x!

For all the haters in here who wanted some proof, that elpida memory sucks in 290x cards:
- use google or ask people with hynix/elpida 290x cards in mining irc chats
- i made a chart comparing mining speeds with my hynix card with an elpida card, same model, same batch.
- i used memclock 1500 and changed the core clock from 850 - 1050. you can see that overclocking does more harm than good with the elpida 290x card

- here is the proof, step by step in this huge image (click and press the 'original' button):


- here is a screenshot running 2 hynix cards and 1 elpida (gpu 2) on 1025/1500

- ofcourse you could finetune the elpida card up to 890 kh/s, changing thread concurrency etc, but the point is, that it has its peak performance around ~920 core clock with 1500 memclock

If you never mined before and want to test your 290x memory:
- download cgminer 3.7.2 (newer versions don't support gpu) from the official downloadpage http://ck.kolivas.org/apps/cgminer/3.7/
- it will give you a virus warning because hackers use cgminer in botnets to earn some coins
- open cmd in the cgminer directory and execute:
Code:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer -n
- cgminer -n will enumerate your gpu devices, use the 290x device number in the following command after --device
Code:
cgminer --scrypt -o stratum+tcp://eu.multipool.us:3352  -u 5andr0.1 -p x -I 20 -g 1 -w 256 --gpu-engine 1025 --thread-concurrency 32765 --gpu-memclock 1500 --gpu-fan 90 --device 0
- feel free to post your avg. 290x mining speed with these settings with your specs here wink.gif

Thank you very much in advance!

Confirmed:

- A miner friend just confirmed 3 x Hynix with *-00 000001 P/N (Cards are from Asus, Diamond and PowerColor)
- sapphire 290x bf4 from ilesef has Hynix bios part number 113-C6710150-102 (see post)
- the gigabyte cards from ShortySmalls, 2x Hynix with -00 000001 (see post)
- sapphire 290x from phallacy with bios part number 113-C6710151-100 has Elpida (see post)

Excellent first post, +rep. I do not have my 290x cards anymore but I definitely encourage people to participate and help out.

Sapphire Radeon R9 290X BF4
Memory config: 0x500036A9 Hynix
113-C6710150-102 (switch right)
post #4 of 59
- Name of the card: XFX R9290AENFC Radeon R9 290 4GB 512-bit GDDR5 CrossFireX Support Video Card (R9290AENFC)
- Hynix/Elpida or Hawaiiinfo output: Memory config: 0x500013A9 Elpida
- If accessible: no
- Otherwise check your CatalystCC for the BIOS Part Number, post only when using retail BIOS: 113-C6711100-101_MBA
- Your S/N (optional): no

Seems your theory is correct.

This card is also unlockable.

Based on your example it wouldn't be correct because you have C67111-00, which should be Hynix and not Elpida. But this is because the theory is for 290x only. I wasn't able to find a 290 Bios Part Number with 01. All 290 non x models are having 00, no matter if Elpida or Hynix :/

That's nothing for a miner and cracker biggrin.gif I will order much more 290x once i made sure the P/N -00 models are Hynix only ;P

All Sapphire R9 290X Tri-X cards use Hynix memory. If you're just looking for some R9 290X with Hynix memory, I'd say go for these.

Ohh, whoops. Sorry. Missed the 290x only part.

Why are you collecting Hynix models and how are you acquiring them? Ebay?

Both of my gigabyte 290x cards are Elpida

GIGABYTE GV-R929XD5-4GD-B
BIOS: 113-C6710150-102

EDIT: it seems a different version of the software has told me good news. I have Hynix chips on both cards.
