Topic: Questions about my first 2 rig (Read 485 times)
Seasonic 1000w would be fine for 3 280x's + Sempron system undervolted. Don't underestimate though, i would expect you to easily tap that wattage out cause 280x's can get up above 250w in a hurry.
I will undervolt so i will not have any issue right ?If i will go up to 975W am i safe ?
Expanding your rig with 290s is simply the questions of 1) do you have the slots 2) do you have the power. 2 more 290s is adding another 600w to the system, so plan for that type of increase.
I read there was issues with this motherboard when use 4 or 5 gpu, how can i prevent ?
Regarding the power i will add another PSU.
As for powered USB risers, i always suggest powered for big cards like 280x's and 290s. Protect your investment. Be safe.
I bought 1X to 16X Powered PCI-E PCI Express Riser Card Extension USB 3.0 + SATA Cable
so is it right investment ?
Thank you !!!

Single core sempron is fine for mining, but it is slow as hell if you need to do any sort of maintenance work. I personally go low TDP dual core because i like giving the OS its own core and the miner program the same.

Hello,
i am going to buy
for 2 rig 2 expandable systems up to 5 gpu each:
MB : Asrock AM3+ AMD SB970 4xDDR3 2100 ATX GLan [970 EXTREME4]
CPU : AMD in04gg CPU AMD SEMPRON 145 AM3 BOX
GPU : 3x r9 280x DUAL X ... with downvolt and previous ROM as the last cant go up to 750KH/s
PSU : Seasonic 1000 Platinum
HD : 1 Kingston Technology SSD Kingston V300 SATA3 SV300S37A/60G
RAM : KINGSTON RAM DDR3 8GB/1600Mhz KINGSTON HyperX blu Black [2x4GB] CL9
SO : windows 8.1
UPS : Nilox Line Interactive 2100VA Server 17NXGCLI20002
CABLES:
total 6 riser usb 3.0 .. 1 meter lenght
Does Seasonic 1000 Platinum, will fit with 3 280x dual x ?
With undervolt each will go 250W so it will use 750W + Mb processor and so on they require around 150W, so total will be around 900W is it right my calculation?
Also for Ups Nilox Line Interactive 2100VA Server 17NXGCLI20002
Is that ok? May i buy also two more battery when it fail i change them?
Can i expand each rig with 2 R9-290 ?
Does the riser usb 3.0 must be powered or it works as is ?
May i need SEMPRON 190 instead 145 ?
Thank you
