Hi friends!
I found not expensive 6990. Is it good to mine Zec on it?
How much speed it could run ?
I think the 6990 uses too much power.

I think the 6990 uses too much power. I know it. Whats the speed ? I mean that CM dont support old gen. cards . so its not optimized and i just wonder how much is the speed

The 6 series cards will be alot less, so they would not be efficient to use. Also if you plan on using it in a rig with newer cards, the RX 480 Catalyst Relive drivers only work with GCN1 and above cards (HD 7xxx and up).

Why no one mines on this pool? https://zecmine.pro ? It has 0% fee ...i'm currently mining on https://zclmine.pro and it is super fast and adorable profit. But, we have to work out zec pool, only 2 miners :/

Lets forget about power cost.

Lets forget about power cost. just get the 7950 or 7970. around 150 to 175 watts and 285-320 sols (my gigabyte 7950 does 320 the others 285). as is an older card you can get one around $50 to $70. The ROI is 4 to 5 weeks

Anyone know how much less power the 7990 draws when downvolted from 1200 mVolt to 1000? And does anyone know what the card draws in total? Core clock set at 900 (original 1000). Cards produce 560 sols/s.

HI! What hash rate i can expect on r9 390 with the latest miner?
Depends on model, bios mods, clock, etc. But typically around 370-410.

My 7990 drops about 60w down by moving to 1070mV. I don't set less.

My 7990 drops about 60w down by moving to 1070mV. I don't set less. I bought a power meter! At stock voltage my entire rig pulled 1300w at Wall! Thats 2 7990 and one r9 280. At 1volt/900 core the rig pulls 910w! 2 7990 only pulls 740w, and that is including one idling r9 280. Running one 7990, other Cards idling, rig pulls 480w. My conclusion is that one card pulls 260w or 130w per core and that is very efficent in my opinion!

Very impressive, it is no point to change to several Rx 470s then. Unless they can undervolt Alot!

I think it is quite resaonable speed. R9 280X SHOULD HASH ABOVE 300Sols/s-- My 3-year-old PowerColor 280X cards hash at 320Sols/s. They are overclocked at 1100 core / 1500 mem (1030 core / 1500 mem stock). The overclock setting is stable for months at a time. Any higher clock settings are unstable. These cards are faster than RX 470 cards, but use more power. Is your power supply enough? My cards run on FGLRX drivers. If you have updated your drivers to AMDGPU Pro (v17.4.3+ is supposedly compatible), your 280X cards may not perform as well. If your cards are running hot (80 deg C or more), they may be throttling. I don't have too many tips, but those 3 items (power, drivers, heat-throttling) are worth a look. You might also try changing the riser, or mounting the card directly on the motherboard. Good luck! --scryptr
