New BIOS in Sapphire TOXIC r9 280x decrease hashrate ?

[Ll_lkasz]

I bought 2 new Sapphire R9 280X TOXIC and I have problem with hashrate.

In those cards is new bios version 015.043.000.005.000000
Im able to get max 600 khash on it.

I have also 18x other TOXICS with BIOS 015.041.000.000.000000, and I get 760-800 khas without any problem.

I've tried to flash bios to the old one but cards doesnt accept it.

Any ideas ?

Same problem here, also, tried BIOS :
 - 015.039
 - 015.041
none of the 2 works.

I am also getting only 620khash.

Damn you sapphire :-(

The problem is "015.043.000.005.000000" Cards are now using Elpida EDw2032BBBG Memory.

The previous version were using hynix memory, which would explain their great hash rates.

At the moment stock BIOS :
GPU = 1050
Mem = 1500
Threads = 8193
powertune = -20

I am able to get 730 Kh/s

On my other card with the hynix memory i was easily pushing 770 Kh/s With the Bios undervolted to 1.112v

I am so disappointed in the Sapphire TOXIC r9 280x cards, now that they have Elpida memory.

I thought TOXIC cards were supposed to be the best of the best of the best? So much for that.

What a blatant bait-and-switch on one of the most overpriced GPUs on the market. Have fun with that.

Oh, and for the record, Gigabyte did the opposite. The initial 280x all had Elpida RAM, and their newer ones have had Hynix RAM. So there's that.

@ BitOrigin

with the ~same setting :
GPU = 1070
VDDC = 1090
Mem = 1500
Threads = 8192
powertune = -20

I am getting a steady 740khash on 2 TOXIC and 1 triX

The new one with 015.043.000.005... with the same settings => 619 avg, and I have much more variation than the olders


Do you mean that there is nothing to do...?
No wizard stuff that can help...?

If so this TOXIC is going right back to seller.

Another question, is there a way to know for sure, the kind of memory used before bying the card?

Thanks

[Equate]

The new models have the new bios and they had throttle problem.If you buy you need to flash them.

I have two new toxics and I can't break 660 KH/s. None of the techpowerup bioses would let me boot with the older bios versions... does that mean we are screwed?

[deesx1]

I'm getting 718khs (015.043):

tc 8192
gpu-engine 1020
gpu-memclock 1500

But it's too low for "top class" Toxic .

[gilad215]

listen guys this is HUGE PROBLEM! i'm planning on buying 10 toxics tomorrow! you suggest not to? i heard the VAPOR does problems aswell!

what now?!?

[N[e]wBie]

If toxic is your only choice, they are probably still a good option if you aren't paying a premium for them. They are running as well as my older gigabyte card (660-700),  less than my dual-x (710-720) but cooler, and they are seemingly fine with a decent undervolt.

very informative thread, so now what is the best vapor-x?

Im getting 750 KH/s with 70ºC temp on an AC + FAN room with this settings:

-I 13 -w 256 -g 2 --shaders 2048 --thread-concurrency 8192 --lookup-gap 2 --gpu-engine 1070 --gpu-memclock 1500 --gpu-powertune 20 --gpu-vddc 1.100 --auto-fan --temp-target 72 --expiry 1 --scan-time 1 --queue 0

this with hynix ram?

[N[e]wBie]

anyone have a good bios or settings for the newer version of the toxic? I have been able to, with a lot of optimizing, get my card up to 690 KH/s, but >700 would be amazing!
-I 13 -g 2 -w 256 --thread-concurrency 8193 1026/1500 are best setttings for me and get me about 690 KH/s

what memory do you have on your toxic?

also try 1100 core 1500 mem

[skleven]

What happens when you run max voltage and 1150 core and 1800men? Mine is stable at 810kh/s at those clocks..

I get 511 KH/s with these settings
