B570 memory upgrade question

[rococco]

I purchased a lenovo b570 with an Intel b950 dual-core 2.1 mhz processor and 3gb of ddr3 ram. Both available memory slots are listed as occupied, so the memory configuration would be 2+1gb.

I would like to upgrade the ram to 6gb = keep the original 2gb stick, and replace the 1gb with a 4gb stick.

I need to know if mixing different brands of ram is possible on lenovo laptops, and what type (brand) and speed (1333 or else) should work. For instance, Crucial's website claims that its memory is good for lenovo laptops. But it doesn't say if it works when mixed with preinstalled lenovo sticks.

Thank you

Thank you for the link.

I would still like to know if lenovo's original memory will mix well with whatever other brand i might install or are there any  known issues?

usually there should be no issue with the supported ram sticks but make sure you are using the same speed of the ram.

I wasn't able to determine whether the RAM in my b570 (cpu Intel b950) is pc3-10600, pc3-10660 or pc3-10666. It only says it's 1333.

I would appreciate some help in finding out if I can safely go for RAM modules branded as either PC3-10666 or PC3-10600.

I don't understand what these distinctions are for.

I am currently using a PNY 4gb ddr3 1333ghz and it runs fine with it I got mine with a 4gb stick already in it and maxed it out. It should not have any problems with the brand as long as it's not a really cheap crappy one. I mean they will work, but no where near as good. Patriot, corsair, kingston, crucial, pny will all work fine with it as long as u use the same basic specs. ddr3,1333ghz the 1ghz is meant for like apples and such. You could also go with a 1.6ghz just faster memory. Good luck.
