They are a horrible company to do RMA on syscooling.  I gave them 3 weeks, neither of my two RMA pumps and one harness have showed up. Talking to their support is painful.   It's not about hurting them just making it right.   I had to open a dispute as well.  

Did anybody notice syscooling doesn't have C1 cooling kit listed on their website anymore? Because of lack of quality control? I was going to order the 4 C1 kit.

Edit: NM, kit is listed on their old website (buy online tab).

why did you open a dispute? Did they replace the "first" one? if so why would you open dispute on the second one? Not sure of your situation just trying to figure out why would possibly damage syscoolings paypal status doing a chargeback.

Yesterday stopped working on my second syscooling pump.
Fortunately, I paid via PayPal. I opened dispute today.

yes you  are that other guy....

sorry to hear about you luck with sys cooling..

@klondike So I will wait for bitmain to consult before I open this unit and void anything. Maybe you're right it is something small. I just find it odd I would've smelt that sweet candly like chip melting plastic small and also two boards be dead??

Regardless bitmain has been emailing me all night (on there off day) which is very nice of them and helps me sleep better.

They asked me for a graphic showing the miner status (which i do not have because its doa) and also to confirm the pump is okay.

Bitmain asked me "what I would like to do". I'm guessing they mean as in ideas for swap, compensation etc. This is what I replied...

me: "I feel like it would be fair to swap for 3x s3 units. I know 3x s3's is 1.2 th/s which is 0.2 more then the c1. This 0.2 extra would make up for the $5/day im losing in downtime on my c1. Also a shipping coupon good toward new purchase of bitmain product would be nice to compensate me for shipping the doa c1"

Seems like a very very fair proposition to me.

So far bitmain has been staying in contact well it seems.



oh yea btw i am running rm1k psu which is 1050 on the rails


fk this is stressful. I know bitmain will come through. They have too. There kindness can't just be some long con ploy can it?

my mind is racing? gotta play sc2 and fire up some purple I guess. Jesus blessings to all


**edit** bitmain got back to me. Said they would RMA any dead blades. Not even sure this is the problem and I do not build miners and I also do not want to void my warranty. I really wish they would just swap this thing out like I was trying to get them to do before the thing even left the factory....

I want reliable rigs not something that I lose sleep over :/

sweet potato jesus what I have gotten myself into :p

please swap bitmain!

One of my C1s is underperforming. It appears that a couple of the chips are dead but no Xs are showing.

I have a feeling i'm the other guy.   It is syscooling I'm waiting for.  Over 3 weeks and no RMA parts.   They are flat out horrible.

Bitmain is a different company.  Email them they have good support and have always treated me fair.   

open up the unit and check all the cables. two totally dead boards is strange, and seems like theres a common issue. Perhaps they are sharing a weak rail on the PSU or have loose cables. if you're tech-savvy at all, its very easy to open the case and spend 5 minutes with a multimeter to check for 12V and 0.7V presence on the bad boards, and if any status LEDs are lit

2 boards on my unit are dead and the pump works fine. machine is fried wat a darn bummer...

praying bitmain blesses me but that other guy earlier is still waiting but i think his was a cooling issue...

mine is just simply toast :////

pleade bless me with some reliable s3's bitmain... please and help me with shipping and a hefty coupon on my next batch of s3 orders sunday.

that sounds fair to me... equal exchange for s3's with reimbursed shipping in form of coupon for my sunday s3 order.

@dogie i understand they do not reply right away. i just pray they follow up well and this doesnt turn into a me nagging them and making me into the bad guy (even tho i have the worlds most beautiful paperweight)

sometimes there are just a few bad or low-preformance chips in every batch. if raising the voltage by 0.01-0.03V doesnt help then its probably not resolvable. even 2 bad chips are only a ~5% below spec, which is almost nothing. There no reason why you cant resell it at a fair price even if its 5% under spec (you might get 5% less for it of course).

not sure if you expect bitmain to spend a week RMA-ing your boards over a ~$25 issue unless its drastically outside the +/-5% spec

how is the unit setup, whats the power supply, what happens when you turn it on? Are you sure the PSU is even providing 850W+ on the correct 12V rail(s)?

Its unlikely to have a unit thats totally DOA - most problems are caused by 2-3 common issues.

The troll was half right, well that's an improvement.

Contact support directly. Dogie is a one line response cheerleader to attract people to his paid links.

I can verify my two were not temperature. It was cold ambient being used from winter winds.   

I wont go into my story again, as I'm sure your all bored of it.  But still over 3 weeks no RMA from syscooling.

Opentoe - Bitmain has a support system.  I'm in the US and have had a bad S3+ board swapped by their folks in Denver.  Their system worked perfectly.  This thread is not their warranty system, so posting here is not the most effective way to contact Bitmain support.

You emailed at 7pm on a Saturday, and its now 1am on a Sunday. Don't be surprised if you don't receive an instant response during that time period.

I'm sure you can find an age-appropriate place to troll, seriouscoin...

I can't help but wonder, the folks with the burnt out pumps, is the pump intake coming from the radiator (hence cool) or the C1 (hence warm/hot)?

That's the newest one. I'll chase to have it uploaded onto the site.
