Well - obviously not an ideal solution, but it turned out to be quite productive taking the circumstances into consideration.
The rig - https://sech.me/boinc/Amicable/show_host_detail.php?hostid=82195.
A Q9400 stock speed with 8G DDR3 800 MHz system memory, 2 HD7950 1GHz with 3G DDR5 and a 120G Kingston A400 SSD.
Letting 2 cores availible to feed the gpu's when needed and setting the pagefile manually to max at 30G, turned out to work.
What i did'nt expect was the wear, or regular punishment of the SSD. 100 hrs of crunching took 3% of the estimated lifetime according to hwinfo.
The A400 120G has a 40TBW lifespan, so it is'nt that big a surprise, but i comparison to around 10 days of crunching took more than a couple of years of light desktop use(!)
Besides delivering a lot of heat and consuming electricity accordingly, it was a fun exercise to realize old equipment in a somewhat competetive way.

Hi Soulfly,

Thank you for posting this information! Just out of curiosity; what are your BOINC preferences settings for memory usage?

That is quite a bit of wear on the SSD, although from my experience they usually go well past their TBW lifespan before any serious errors develop. I've got a 60GB OCZ Vertex 3 from 2011 with over 180TBW in one of my BOINC-only systems and (if I recall correctly) the warranty was for 75TBW. A few bad blocks, but nothing showstopping :)

Regards,
Kellen

I set the memory usage to 95%/95%. The result is that the computer becomes very irresponsive when the tables are read into memory. In other words it was crunching and nothing else.
I doubt i will ever wear a SSD down, reaching or exeeding the TBW lifespan. So far i've only lost 2 SSD's due to the SATAFIRM 11 issue that can happen with SSD's with the Phison 11 controller.

Exeeding TBW by more than 100% and still going strong is quite good value for the money :)

Hi Fred,

That's awesome; thanks for the info! I will try to get some of my 8GB systems running with these settings too towards the end of the year and we will see how they do :)

You and I have very similar SSD experiences. I've never worn one out, but I've certainly had a few controller/firmware failures.

Thanks again,
Kellen
