Memory & MB Issue - 4.00 GB (3.25 usable)

Hello,

I have been building a PC from some spares from work and I am having an issue with the MB not recognising all of the memory. I had the same issue with another PC which had an Asus MB which is why I switched to one with an Intel DP965LT which can take up to 8GB. I am running Windows 7 64bit and have included part of a Sisoft Sandra report below to help.

Can anyone help with the following questions:

1) Is there a way to fix this memory issue so it is all usable?

2) This MB has a LG775 Socket with Pentium D 2.66GHz processor. What is the maximum upgrade on this socket type?

Thanks in advance for any advice or help. I am happy to respond with further info if it would help.

Russ

More about memory issue usable
  1. With bios version 1698, I recommend the q6600 or q6700; don't pay more than $100 for such an old motherboard processor. For a flash program, search Intel's website. http://www.cpu-upgrade.com/mb-Intel/DP965LT.html. For ram and cpu upgrades, check craigslist or anandtech's for sale forum (registration required). For ram, you can use up to 4 sticks of 2 gb pc6400, but I don't recommend you spend so much for such an old board, especially when 8 gb of ddr3 is going for as low as $25. 3.25 gb is plenty to run most applications. My old boards all showed the same usable ram as yours with 32 or 64 bit windows 7 and 4 gb of ram installed.
  2. Thanks for the info, that is a great help. I will definitely check out the craigslist as well.
  3. It appears you are running miss matched memory.
    The timings and manufacturing dates are off and made 2years apart.
    You may not get all 4 sticks to work because of the different timings.
    The motherboard can not set a speed that will work for all 4 dimms.
    Try with just 2 matched dimms, the ones from 2007 in matching slots.
  4. What Rick said.
  5. ahh, rookie mistake <shamefaced>
