Topic: Litecoin: 1x to 16x PCI-E extenders, CPU question - page 2. (Read 7706 times)
Burn that shit to the ground. Go LTC.
Alright, sounds good. I'm going to do some more research and probably end up getting a board with only 0-2 1x slots that I need to run cards on. It seems like powered risers are somewhat hard to come by and I'd rather not deal with making my own.
Either way I really appreciate the advice; thanks again!
I'll post here to warn you & others if anything I try blows up. :p

Sounds great... now one more question; do you need powered 1x to 16x risers?
I have a bitcoin rig with 2 unpowered 1x to 16x risers for 5830s and they run fine but I see some people saying you need powered risers.

It depends on how many gpus you are running and what gpus they are really. I've ran 4 just fine on no powered risers, but then I tried running 5, and melted the mobo. If 3 or less I would say no. If 4 then the answer is probably just to be safe. You might be living dangerously if you don't have atleast one powered riser. If 5 then I would say it is a requirement.
I was considering doing 4x 7950 on a motherboard with at least 2 16x slots, so I'd only need 2 1x risers.
I was also considering using this board with a Sempron 145: http://www.amazon.com/gp/product/B0055QYKQO/
With that board I wouldn't need to worry about 1x risers
You're probably fine not using any powered risers on that board using 4 GPUS total.
Wait for someone else's confirmation of that though. I'm running a couple of 4 GPU rigs with no powered risers, and not having any trouble. I just hate to tell you, you're fine, and then have your mobo melt.

amd is cheapest. you can get a sempron and mobo with support of 4 gpus for around 130 combined on newegg. add ram (i suggest at least 2gb per GPU for ltc), PSU, and a usb drive and you have an open air mining rig for <$300 before the gpus.
Thanks for the advice everyone!
Do you recommend an AMD or Intel motherboard/CPU?
Also do you think it's a better idea to get a CPU/mobo with integrated graphics, or is it okay to use one of the mining GPUs for video? (this would be a dedicated mining rig... it would just be sitting there with a terminal running cgminer)
Ty again!

I've never used a mobo with integrated graphics for mining, but I have heard quite a few people say that can cause problems. I use one of the mining GPUs as video when I need it. There's no problem in doing so. That card may run just a few degrees hotter than the others on the rig I've noticed though.
I've used both AMD and Intel. Haven't had an issue with either, so not sure one is better than the other. It may just be whatever the best deal you can get is.

no noticeable performance decrease unless your rig is underpowered. no need to worry about the cpu, cheapest is fine, youll be using the gpu.
Yup spend the money on the GPU and the extra 100 for a rock solid PSU. Go with PCpower and cooling, or heck corsair and seasonic.... just because it say 1100w on the sticker dont mean its high quality.
Also, try to make it a single rail PSU. Not as critical as some people would have you believe, but if it is a multi rail PSU you have to pay attention to how you balance your loads. I overloaded a rail one time on a multi-rail PSU and the thing died really quick. Luckily no other hardware was damaged.

Edit, you can go even with an older gen sckt 775 chip/mobo and get em dirt cheap. Toss in a small HD to load the OS and your gold.
I'm consdering building a litecoin mining rig. I know that you can use 1x to 16x PCI-E extenders for BTC mining rigs but I also know that LTC is more intensive on GPUs, so I'm wondering if a 1x to 16x extender will decrease perfomance.
Also, do you need a decently powered CPU for a litecoin rig? Will the cheapest Celeron or cheapest single-core Sempron work?
Any advice is appreciated... thanks!
P.S. Sorry if this is the wrong forum or if these questions are answered elsewhere. I tried a quick search and didn't find anything.

the 1x to 16x PCI-E extenders work perfectly fine for LTC rigs. I have numerous rigs running with numerous of those adapters, and no problems. The cards on 16x -> 16x do not get higher performance than the cards on 1x -> 16x.
Also you only need the cheapest CPU. (Still go for 64-bit though, in case you're thinking about a really old processor that is only 32-bit). Other than that the CPU is irrelevant.
You might want to throw in more RAM on a LTC rig than a BTC rig, but if you're using cgminer, that isn't critical either.
