Hey Guys,
I have an r7 370 that is not recognized anymore. The fans are spinning but Windows/Linux cannot see it
Since it has never happened to me before am i looking at a burnt card?
I have a card that keeps dropping from windows 7 - well stops being recognized, yours sounds worse than that but I simply plug it into another slot and it shows up again after a second reboot. I have a feeling the card is about to die but I'll keep switching it until it does. just a thought

Thanx a lot

Since its a 370, you most likely still have warranty on it, send it to the manufacteur.

For all you unbelievables here are the results after 20 hours (look at the low rejection rate) I also have a 7950 in another rig running at 285H/s If you aren't getting these speeds, hack your memory straps, use 15.12 drivers, use windows 7. The other 2 slower Tahitis are 1000mhz core clock because they are the crap Gigabyte windforce and overheat easily so I can't run them at 1100mhz, however chances are they would run at 330h/s under 1200mhz. So the hashrate is clearly linked to engine core clock speed. However for them to run at 1200Mhz you would need to run at stock voltage or overvolt and your power consumption would be in the Scrypt Litecoin power consumption terrority. I am talking about 300-350Watt per GPU at the wall. Not worth the extra speed boost. Especially since the Gigabyte Windforce 7950/7970 were known to catch fire during the litecoin days. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi68.tinypic.com%2F14sjosn.png&t=665&c=9AHIK-dWEWtdAg)

I run my Tahiti's at 975 to keep them under 160 watts @ 270s/s. Don't think the extra 10-20S are worth the 50-100 watts per card.

Hi,
I have a problem if I try to connect more than 6 GPUs to my AsRock H81 Pro BTC v2.0 mobo. I bought an extender riser (PCI-E x1 -> 3*PCI-E x1) and I use normal USB3 PCI-E x1->x16 risers. Everything's fine until I connect the 7th card. I can connect the first 6 card any way I want it but after the 7th card connected I got blank screen when I turn on the rig.
How do I make it work with 7 or 8 cards?
are you using Windows 7 perhaps? I have an 8 Card system and the only way I got them to work was with Windows 10 and Ubuntu. But it can also be the fact that your MB don't support more than 6 PCIE cards. Have you tried connecting 5 cards and one dual card? such as 7990, 295x ? I have two 7990 and 4 other cards in my 8 card system. Not using the PCI Switch. I use Win10, but I can't get to boot the OS. I turn on the rig and nothing happens. I don't have dual cards, I use RX470 GPUs. Maybe AsRock H81 Pro BTC v2.0 mobo doesn't support more than 6 PCI-E devices? I tried to disable integrated audio, serial ports, etc. in the bios, then connected the 7th card but also didn't work. I don't want to buy an expensive server/workstation mobo. Is there any chance to use 7 or 8 PCI-E devices? I searched for modded bios for this mobo but didn't find anything. Or it's the limit of the H81 chipset, not the bios?

What clocks are you used? p.s. timings are 1250MHz

Strange ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) I tried to mod bios, but i did not achieve any increase in performance. Maybe you could share your bios domp of 280x? atm i get 245-260h/s

Hey Guys,

Since it has never happened to me before am i looking at a burnt card?
Had the same issue, its mostlikely dead, try it in another rig and if it still not working its most likely dead, When you will try in the other rig, make sure its not on a riser, has to be on the MB slot. Thanks I will try this first Thank you @kdepfyffer i have tried multiple risers and rigs. I think its burnt @adaseb- I will probably do this in the end ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Thanks everyone for your thoughts and contribution

I think it's becouse there are different processor in 7970 (XT) and 280x (XTL). I was trying to set 1133/1600 in bios, but card is froze computer, and i will restart it only on evening ![Undecided](https://bitcointalk.org/Smileys/default/undecided.gif)

My rig show only GPU0 and GPU1 temp and fan, i have 2x 7990, under win 10, already tried all from catalyst 15.12 to 17.1(used ddu), tried all sort of config command(-asm 0, -tt 75,75,75,75 -wd 0). I'm worried because i used the command -ttli and -tstop to protect the rig, but that seems to affect only gpu0 and gpu1, already see gpu2 and gpu3 get to 100 celsius.... Already tried miner 10.0,11.0 and 11.1 Any tips?

The maximum that I have seen on my 280x and 7970 was 250 h/s. How can I get 290 h/s? Do a modified BIOS provides significant increase?
