Hey guys, love the miner but I'm having a super frustrating problem (I recently switched to x11 from scrypt). I use the miner on two computers, one upstairs is a 5850, and 270x which hashes just fine and never crashes. The second miner is the basement --two R9 270s, one R9 270x, and two R9 290s. This rig hashes fine for 20 mins - 2 hours until I get the message: "stratum connection to pool 0 interrupted", and sgminer just hangs and stops mining. The computer doesn't crash and I can close sgminer and restart again just fine. I get this same message every time it crashes! I know I have it set up right cause I get 12-13MH and wafflepool accepts my shares just fine. I've run this rig for months on scrypt and never had internet or connection problems so it is definitely not my computer / internet.
Here is my config file if it is any use.
{
"pools" : [
{
"url" : "stratum+tcp://useast.wafflepool.com:3331",
"user" : "my address",
"pass" : "d=0.16"

Hi, I have the same issue. I was googling some advice with no luck...
I will be happy to share my experience:
- decreasing intensity has no positive effect,
- decreasing engine clock was an improvement of stability with no significant hashrate decrease,
- using default GPU BIOS (without memory timing optimization) seems like a solution. (so far 3 days of stable mining, heureka).
I was using modified GPU BIOS with optimized memory timing increasing hashrate when mining with scryp algo. When mining with X11 algo., using default GPU BIOS (default mem. timing, default voltage) is not decreasing the hashrate.
I have 4 GPU Saphire 280x, two of them Dual-x, two of them Vapor-x set on:

total 12,2 Mh/s… using bootable USB with updated PIMP 1.55 (pimpupdate of X11/X13mod miner did not solve the problem).
Hope this helps, anyone with more experience please comment…
