Prime,

I agree that ram shouldn't produce errors. However, what happen if memtest is clear with your testing, but another test program, eg goldmemory produces errrors? I know for a fact that goldmemory is a much tougher test than memtest, but where is the limit? Are your limit zero errors in memtest but ok with an error in goldmemory?
I know what you are going to answer but you know what i mean right?

Edit// To stay on topic. I actually didn't like the article since nothing explains what modules in memtest is for mainboard, memory controller or memory. #5 and #8 is memory based, we all know that. If you are testing memory, all except 5 or 8 is more or less useless and time consuming. And as Geeky said, error in memtest doesn't have to be the memorys fault. A little explanation from the article writer in this area would have been nice. Just my 2 pesetas.
