very sad, dude
if 3GB Dag file this month, VRAM 3GB  become is game over.
yeah, lucky me, at the time of AMD 8 GB release. at that time I decided to buy VRAM 8GB, even though it was VRAM 8GB very expensive. but if VRAM 8GB compared with the current price of course very .. very cheaper.

Ada beberapa tipe USB Riser yang biasa digunakan dan ada perbedaan diantara tipenya. Saya hanya membahas sedikit USB Riser yang biasa saya gunakan diantaranya:

1. VER008C



2. VER008S



3. VER006C



4. VER006



Kriteria USB Riser yang bagaimana yang baik digunakan?

Untuk saat ini, saya hanya mengetahui dan menggunakan Versi semua USB Riser diatas. Dan saya ketahui perbedaan dari penggunaan Riser tersebut terhadap performance mining, khususnya terhadap VGA. Yang paling bagus VER008C.

Jadi bisa saya simpulkan Kriteria nya seperti berikut:

1. Led Indicator, sebagai penanda bahwa USB Riser tersebut sudah teraliri Listrik DC (PSU).

2. Jumlah Kapasitor (VER008C, contoh diatas memiliki 4 Kapasitor). lebih banyak lebih bagus.

fungsi dari kapasitor ?. fungsi kapasitor itu banyak sesuai dengan rangkaian electroniknya dan penggunaannya. Akan tetapi fungsi kapasitor pada

rangkaian USB Riser adalah :

-Untuk Arus DC berfungsi sebagai Isulator / Penahan listrik (dari PSU)
-Penyimpanan daya listrik sementara.

Terus apa kaitannya dengan Jumlah Kapasitor tiap USB Riser berbeda?

Kaitannya adalah semakin banyak Kapasitor pada USB Riser menandakan semakin bagus kualitas USB Riser tersebut karena? (kembali pada fungsi kapasitor tersebut).

Kita ambil contoh pada VER008C , USB Riser tersebut memiliki 4 kapasitor dengan spesifikasi 

330 arti singkatnya 330pf,

25V  Artinya Tegangan DC maksimal yang bisa dilewati, DC disini berarti tegangan dari PSU.

SYK artinya Toleransi kapasitansi nya  +- 22%,suhu kerja minimum -30 derajat Celcius dan toleransi koefesien suhu +- 250 derajat celcius.

Jika USB Riser memiliki 4 Kapasitor berarti :

330 x 4 = 1320pf

25V x 4 = 100V

Berarti USB Riser tersebut memiliki 100V maksimal Tegangan DC yang bisa dilewati, jelas hal ini berbeda dengan USB Riser yang hanya memiliki 3

atau 2 kapasitor dengan variable besaran Volt yang sama, apalagi tegangan Volt yang lebih rendah.

Saya tidak terlalu detail membahasa baris ke 1 dan 3 (seperti SYK) karena tidak terlalu paham, silakan bagi anak-anak electro bisa menjelaskan lebih detail.

3. IC berfungsi sebagai penghemat dan penyimpan daya.

4. Voltage Regulator Protect.

5. Konektor Power 6 Pin.

pada tegangan 12 V (kabel kuning), konektor power 6 pin memiliki 2 kabel tegangan 12 V (kabel kuning), berbeda pada konektor power 4 pin, hanya memiliki 1 kabel untuk tegangan 12 V.

Kesimpulannya:

Saya hanya sharing tentang perbedaan dari penggunaan jenis USB Riser.

the 106-100 almost same 1060 6GB, has a couple bit modification. better a mining on Zcash.most famous from NVIDIA is lower Power Consumption compare the AMD card.but for AMD more tweak-friendly

do you mean air from out to in your garage? or air from your garage to out?.

Mining on ETH or ETC coin, so far AMD card especially series RX excellent on the Ethash algorithm compared  Equihash Algorithm (Zec coin). if you want to know the what a difference from both, you can do mining on both (the means isn't dual mining) and if you want additional a hash rate you can do mod bios.

that's nice, dude
and don't forget you must have the PSU enough power for those devices.I suggest you get RX570 8GB, this's done for anticipation for DAG size 4GB (if you want mining on an Ethash algorithm such ETH or ETC).

on the architecture, the difference between the two is only on RAM and chipset. if Asrock DDR3 and CPU Socket 1150 then TB250 DDR4 and CPU Socket 1151. Asrock H81 cheaper than TB250 but TB250 has the M2 slot for can used add a GPU again. in the performance on mining both the same good.
if you want to save a bit money, you can choose Asrock but if you want to add 7 GPU  you can choose TB250 and buying M2 to PCIe adapter (if using M2 slot)

just share
you need modifying your RX580 bios and then Over Clock it. One of my RIG is 6x RX580 8GB, mining on ETH, I making $12 per day (price of ETH at this time)  with mod plus OC.

a problem that, can also happen because:
1. Virtual Memory too small
2. Power to a GPU is lack power.
3. RAM on CPU has a problem.
4. update windows
5. and like @leonix007 said: maybe the USB Riser is broken.

yes agree,
except VRAM type doesn't can check before but can check after buy. especially AMD card more powerful if doing modded and OC(about the hashrate), but power consumption high if compared an NVIDIA. yeah, every series of GPU has deficiencies and their respective advantages.

thank's for suggested

big thank's @manji has been explained my point

1080 has TDP 180 W x 4 = 720 W.
if Often read about PSU, you will know, why PSU must have space between 200-300++. read also how the PSU impact if power shortages and RIG that has a small space power. I have experience, the RIG has lack power.

this is a fact :

I suggest you OP and write in detail your experienced about mining using a laptop especially MacBook Pro and  kinds. because of has a ton of thread the same question. maybe with your experience can answer all the someone would mining using that device. almost all member including I doesn't suggest mining using laptop or Mac. in principle and architecture of that device can analysis:
1. almost all laptops (Mac, and kinds) doesn't design for mining (atm).
2. has a little fan.
3. batteries not designed for running 24/7.
4. casing which is not possible to remove heat temperature.
5. the hashrate generated a small if compared Using GPUs.

it's ok if only for learning. you can try mining the ETN coin. follow this step:
1. joined the Pool (you can search with key "Pool of ETN" or anything).
2. Download a software such this: Claymore CryptoNote CPU Miner v3.9 - POOL
3. and a bit must change CONFIGURATION FILE. for the detail, jump to this thread:
https://bitcointalk.org/index.php?topic=647251.0

But if find for the profit, I suggest you don't do mining using Mac. that's a device not design for a mining and must run 24/7, it makes a Processor worked 100%. and most very important if using Mac, you would have a bit the hashrate.

what the means of small timer? (skip..)
he/she isn't miners. if you ever experienced mining coin ETC, when at that time Fork 1:1 become ETH coin, At that time I only had 1 RIG and I get profitable comparable to 2 VGA R9 290. one case else example when a mining Zcash, first release software for Equihash Algo (because when Zcash released, still CPU based). since then I mining Zcash for 2 months and I have profit can buying 1 RIG again complete (only in my country). and until at this time, I still do mining on Ethash Algo and so far still profit after paying the electricity.

if you suggest better a regular job and just buying crypto. I feel that's less precise because a regular job also not necessarily better than a miner from in terms of income. the different of miners can full a control their income without must wait for a monthly salary and said 'hello boss every morning'. and expect the boss to give a bonus in every month and Christmas day.

you can read this article:
http://cryptomining-blog.com/tag/eth-solo-mining/

too very difficult to have the block with your Hashrate although all of the RIG in Modded and OC(exception). the Network Hashrate and Network difficulty is very higher. if you do of Solo Mining, you must wait 1 month or 3 month or 1 years or can also can't get the block. it's all only wasted time and your GPU only worked a free. but if it's just curious to know, how the process Solo mining, you can do it.

almost same on the architecture, the different on PCIe Slots. Asus Prime Z270-A, default can be used 7x GPU and be equipped M.2 (can using for add GPU). Asus Prime Z270-P, default can be used 6x GPU same the equipped M.2.

you indirectly say that you are a hero, a winner and even you are the smartest person. Would like to give you a merit if your calculations match my calculations. the reality, I'm every 1 month can buying one new GPUs from the profit the mining after electricity cost. maybe I false on calculate.

actually, if a CPU would be used mining, Intel Celeron/Pentium is enough. I think if you suggest i7/i9, only wasted your money. same with RAM, for mining 4GB, is enough.
