Right i recently put together a new system which to keep it short had some problems with the memory (or so it seems)

one bit of advice i was given was to look at the voltage across the sticks

my questions are as follows

how necesary/imperitive is it that the actual voltage/timings applied to the RAM correspond to the manufacturer recomended ones

for example the system i had problems with was
MSI P55-GD65 motherboard
OCZ Obsidian 4GB (2x2GB) DDR3 PC3-12800C9 RAM

im not sure i got the right wording/definition for it but the
"recomended settings" say
1.65V and timings of 9-9-9-24

the bios by default has both of these settings on auto
for the voltage this is 1.5v and the timings 7-7-7-18
 
try it on auto mate, what problems do you get also are your problems at auto or manual settings as carnt quite make it out
 
spd is not always read correctly by the mb, i always set it to manual.

its not 100% important to use the ram manufacturers guide, but you definitely should to begin with. at least then u know if there is something wrong with it or not.

Edit: in this case its obvious the spd is not being read correctly for ur rams recommended top settings, maybe its set to the lower frequency, post a cpuz screen shot if possible. looks like u definitely should set it manualy

Well originaly on auto i was getting more BSOD errors than i have ever seen before with a lot of help from people on the forums it looked like a RAM issue so i ran memtest and got tons of errors there, i then changed the settings to the ones that are recomended yet i still recieved errors in memtest.

So ive recently sent back the sticks for a refund and ordered a different set and i wanted to make sure that im doing everything right if that makes sense

Also the majority of errors come from trying to install windows, when i managed to get it on the machine i get random crashes, crashed when i try to load up a program, crashes when i try to install drivers from a cd pretty much any time i try to do anything.

SO basicaly yeah im 99% sure that the problem was with the old RAM but i want to make sure.

definitely. i think its now common practice to have to manually set ram to the manufacturers settings these days. i had to do it with all sticks of ddr2 that were rated above 800MHz and all ddr3 rated above 1066MHz.
 
New ram arrived a couple of days ago with the settings stil on auto i booted up memtest and recieved no errors whch was a releif compared to the half ton i got from the old ram.
 
cool, now do it manually to the manufacturers guide and check again. if thats all clear as well u should be good to go :)
