Socket 775 LGA

Memory: 4 GBytes DDR3 532.1 MHz Dual Channel

 

Yes i saw those specs on lenovo website, but i didn't understand if it only supports a total of 4Gb or it can go up to 4Gbx2.

It's 4GB per slot. So, yes, 4GBx2.

DDR3 was not common for Socket 775.

 

DDR3 DIMMs can be 8 gig each but the chipset controlled RAM back then before i-Series and had a upper limit of 8 gigs as I recall.

 

After that, it is up to the BIOS to make sense of the RAM config so depending on availability of BIOS updates for that computer, the total limit could actually be 6 gigs or 4 gigs.

 

So you should make sure you order RAM where you can RETURN it.

 

1. Update BIOS

 

2. Try a 4 gig DIMM in one socket and one of your 1 gig DIMMs in the other to see if you can exceed 4 gigs

 

3. If 5 gig works, then you will either end up with 6 gigs or 8 gigs total depending on BIOS

Actually, they don't usually update old 775 boards/laptops.

1. But of course they do! 

Back when the unit was first made, it might have received several updates over the following year or two..

 

2. My advice does not include a free mind-reading service as to how the unit was maintained "back in the day"

 

3. So my advice to Update the BIOS makes sense since a non-enthusiast device was most likely NEVER updated even back when updates were being made, so there is a reasonable chance that a (very old) update actually exists even though that may shock and surprise you.

 

4. It would have been irresponsible on my part and plain silly NOT to have made this suggestion.

 

5. You don't watch enough Dr. Who, since it is just a matter of "Timey-Winey" thinking...

That doesn't mean they did...

I honestly can't tell if you are doing a subtle Monty Python joke routine or not.

 

Which means others reading this thread in the future might have the same difficulty trying to figure out why you want people to read tea leaves and not bother to check for BIOS on the assumption that major PC Manufacturers have somehow run out of disk space to host ancient BIOS downloads.

 

So to Other Readers.... TO BE CLEAR:

 

ALWAYS download and update the BIOS of ANY older computer you are working on, or having issues with. Since you never did this in the past, there is almost a 100% certainty that an IMPORTANT BIOS update will be waiting for you.

 

This Simple First Step can save a lot of hair pulling and analysis from people trying to help you!

Hmmm, there just has to be something else worth our attention....

 

This one looks worthy of some investigation:

This a70z has me confused.  Apparently there are different models...different memory types.

 

Crucial has this DDR2 listed for model types 1165, 1184, and 1186

https://www.crucial.com/usa/en/thinkcentre-a70z-(type-1165,-1184,-and-1186)/CT1210696

 

...but on Lenovo's website it has DDR3 listed.

https://support.lenovo.com/us/en/solutions/migr-73825

 

....for model types 0401 and 2565 it has DDR3 listed ...

https://support.lenovo.com/us/en/solutions/pd001552

 

...and the Thinkcentre manual has ...

 

For machine types 1165, 1184, and 1186, support up to two double data rate 2 dual inline memory modules (DDR2 DIMMs)

For machine types 0401, 0994, and 2565, support up to two double data rate 3 dual inline memory modules (DDR3 DIMMs)

¯\_(ツ)_/¯   CPU-Z would probably be helpful.  

 

Also...running 32 or 64 bit Windows?
