new rig, cudaminer runs fine for 1 min then explodes

[wuzamarine]

I have twin tesla k10s on and ASUS z87-plus board. No obvious errors. I start cudaminer with   ->    cudaminer -H 2 -i 0 -l auto -C 1 -o stratum+tcp://mining.updamoon.com:9008 -O tunae.tunae:1  and after a few seconds I get;

And we think we are rolling!

Then, after about a minute, i get;
[2014-02-16 12:33:16] GPU #1: cudaError 30 (unknown error) calling 'cudaMemcpyAsync(context_idata[stream][thr_id], X, mem_size, cudaMemcpyHostToDevice, context_streams[stream][thr_id])' (salsa_kernel.cu line 923)

And I have to reboot to recover.

Any thoughts?

To be fair, I'm bumping this thread because I'm now suffering from the same problem. My KFA2 GeForce GTX 750 Ti is suffering from the same issue. When I've overclocked it to run at ~300Kh/s, it reports the errors the same as OP above, yet when it runs at ~260Kh/s, it runs fine. Only trouble is.. I'm losing out on those 40Kh/s and I'd rather not.

I know my GTX 750 Ti can do ~300Kh/s it's just this error keeps stopping it.

Any help?
