Hey folks i just went back to use my iGPU to crunsh for seti, sofar so good.

Then i thought, is that all ? I mean always said you can`t overlock a Celeron G1820 cpu, but what´s about graphics ?

So i overclocked easaly my graphcis core +150 Mhz , temps at 50°C.

You could do that too, but it´s always dangerous to you cpu, i just want to remind you about this before.

It´s from Intel and easy to use, cross your fingers if u clock. D

Message 1803473 - Posted: 19 Jul 2016, 10:09:42 UTC - in response to Message 1803471.  

With Intel's APU devices always worth to check total device throughput, not just GPU or CPU parts. The reason - they very strongly interrelated. Crunching on iGPU can decrease CPU part output in big degree. And vice versa.
So, check your device output being CPU-nly, then with iGPU enabled (and/or overclocked). Quite possibly best throughput will be achieved for smth between idle CPU cores and full-loaded cores+iGPU...

ok, i raised to 1,250 Mhz , also applied Lunarics for cuda5.0 (broken GT640).

I´ll hate to waste time.

Is there any project (active) that have short worthy nice plesant workunits to crunsh ? First of all i search on WCG.

Nothing found on WCG, but on Collatz , slow on crunching but points.
