Re: 4x 7850 vs 2x 7950 differences (all sapphire standard dual cooler series)
just curious what exactly is the pricing for the 7850's in your area? You might want to consider some of the FPGA's if your GPU pricing is indeed double the cost of the US.
Sapphire 7850 1GDDR5 == 330 U$D
Sapphire 7950 3GDDR5 == 670 U$D
I have considered FPGA but the price is ridiculous, for example ZTEX Quad is 900 EURO, in my country will cost 1700 EURO, this price is crazy!
The only way it would be cost effective is if I buy the Spartan 6 chips and assemble the boards myself, which is what I have in mind, I have worked in electronics with microcontrollers and microprocessors all my life but no experience programming FPGA so I will have to learn VHDL (already get the xilinx dev. software
)and since I am a little late for this, I think that design a FPGA that can mine LTC will be the way to go, maybe using 1 DRAM chip of 1GBit or 2Gbit densitiy per spartan, just thinking, i have to investigate it, but I will really do it
as far as I can get enough mining profit to buy the DEV board (which are also crazy expensive here (around 2000 U$D).Quote from: Bitsaurus
If you have access to reference design cards and can tolerate the noise go for those. They cool the VRMs and pretty much every component well and are very reliable. Plus you can undervolt, and then keep tweaking to max out MH/s and still stay in the mid 60Cs.
I have read that fan dies very quickly in reference design cards, I don't mind noise, my room already sounds like a datacenter and I sleep like a baby with it
hehe.is it safe to lower the voltage?, if I kill a 700 U$D card i will kill myself heehehe (well maybe not, but it would be serious hehe)
