First I want say a quick 'hello' to everyone, it's been a long time since I posted, but I'm sure glad the forum is here when I need it.
So, getting down to business..
I received my little JillyJally back in late November, (mid-April order, sans upgrade)
and to my dismay, it would never reach 5gh/s, it averaged about 4.7. Things were going well with it and it was hashing along fine for about 2 months without major issue. Valentines Day I noticed that the hashrate started to drop down to 4.5 (I love you too BFL), but I didn't think much of it at the time. Given that 4.5 is still within the 10% range of variance, I simply chalked it up to getting the bare minimum from my order. Yippee!!
For almost a month it had been running pretty smoothly at 4.5 and then over the past week I've noticed that it's dropped again and now sits around 4.25. All along the temps have been around 44C and HW errors around 5%, which from my research is about normal. And oh yes, from day 1 I have had the outer casing removed, but top and bottom plates are still on and switched the fan to blow downward, as per the research I did before my unit was shipped.
Today I was a little frustrated knowing that I was supposed to get a Jally with a 10% variance from 5gh/s and my unit is now more than 10%. Grrr.. So I decided to shut her down and check her out, given that I haven't touched her in a few months.
Even before I had her unplugged I noticed that my heatsink was loose and was like "WTF?" So I popped the feet off, grabbed a torx and took it apart to tighten it up. And Ughhhhh!!!
The screws holding the PCB to the heatsink were completely loose. The thing wobbled like my grandmother behind the wheel. So, being curious if the chip(s) were damaged, I pulled out the screws and wanted to check it out.
Stupid ZAIRA (292 or 274) or whomever put my unit together didn't use any thermal paste. SRSLY WTF? Is this normal? Two chips. No paste. WTF?
I had some thermal paste leftover from building my Hackintosh, so I put a dab of paste on each and put her back together. But I still don't get close to my original 4.7gh/s. I didn't see any damage to the chips or anything else during my inspection. I do however get close to the previous 4.5gh/s with 4.41gh/s
As with the consensus, I'm very unimpressed with BFL. Does anyone have experience with RMA their sub-par Jallies?
