Added 4G of RAM…now showing 5.2G
Mobo: Intel DG35EC
RAM: 2×1G Corsair Twin-x 800MHz
CPU: E2180
I picked up another Twinx pair today, 2×2G 800MHz. When I added the new RAM the system booted up reporting one of the 1G sticks as 256MB. I have the newest BIOS.
If I swap the 2G sticks to channel B with the 1G sticks in channel A the system wont boot.
I’m starting to think there is a problem with the mobo.
Any thoughts?
Figured it out. My RAID card isnt playing nice. If I pull it the system boots up showing the proper amount of RAM.
Weird.
Do you really need 6GB of RAM, though?
Yea it seems to wreak havoc with the 4th DIMM socket on some chipsets.
I was using all of the 2G I had and the 2×2G pairs were on sale.
lulz
Yep. 4 gigs would have probably done the job just as well, but like I said, 4 gig kits were on sale. That and I don’t have any other computers that use DDR2.
Hmm. That doesn’t explain the other missing 512MB, does it?
How much RAM does your video card have?
Using onboard video
Either way I fixed the issue by masking pins B5 & B6 on the PCIe connector (SMBus pins). I guess its a problem the Perc 5 has with most Intel desktop chipsets.
