Hi
Just borrowed the mother in laws laptop (samsung R40) this week, running 32bit windows 7, but its only carrying 2 X 512mb DDR2 Ram Chips.
I have a 1GB spare and have tried to ut this in place of both ram slots(i tried both because i was unsure if it had a primary slot or not) and it works fine for about 10 mins, a LOT quicker even though its just 512 better off, and then BAM blue screen and when i try to re-launch the display is all messed up and doesnt even get to the bios loading screen. until i change the Ram again???
Any ideas?
i have searched google to see what it can be upgraded to and that says up to 3.5gb so im stuck.

Any ideas?
Thanks

have you checked the memory model is exact and compatible with the motherboard - www.crucial.com will help and also has an online test

[matmanlives]

been on crucial,it says "DDR2 memory with support for DDR2 PC2-5300, DDR2 PC2-6400 speeds." which is what it says on my 1gb card. does brand make any difference? other than that it seems a perfect match

sorry link not working

RAM maybe faulty - do you know if its works in any other PC OK

[matmanlives]

yeah, worked fine on my other laptop.

on the crucial site what ammount of memory is the max that you can put in each slot. The max maybe 512mb in each slot and it may be confusing the laptop.

it says its upgradable to 2gb, and when the chip in, it works for 10-15 mins fine and registers in system overview as 1.5gb ram on bard

Have you currently got 1gb + 512mb in the computer?

no, i have had to take out the 1gb and put the 512 back in to use it.
i have had the 1gb card and a 512 card in there, and it seemed to work fine for about 10-15 mins then, first time it gave me blue screen, so i changed the ram slots over, thinking i might have to put the 512 in the primary slot as its what the laptop came with.
the second and third time i booted up, with the 512 card in slot 1, i didnt get bluescreen, it just shut off, kind of like an overheat, but when i switched back on the bios screen would not load fully and the display was distorted.
i was wondering of the motherboard was overheating due to the better ram card being used, but if it is upgradable to 2gb then it should be fine shouldn't it?

any memory voltage settings in the bios - if so what are you set to

[matmanlives]

none that i can see pal

Have you tried just the 1GB module in the laptop on it's own. If they are different speeds and the laptop motherboard runs the slower one at the speed of the faster ram module then it will cause those sorts of problems.

is there a way around the that? only there would be no point upgrading unless i had 2 ram chips. if you know what i mean?
