Downloading and installing the latest BIOS firmware for the s3200n from the Software and Drivers page seems to have fixed the problem: There have been no errors in ~15 hours of testing (i.e., twelve complete passes) when testing both 2GB DIMM's together (i.e., 2 x 2GB) using ver. 1.65.
Memtest86+ works just fine but the system spontaneously reboots without explanation during daily tasks: This usually happens during CPU-intensive operations (e.g., compiling a Linux kernel or watching a YouTube video in HD) but not always.
The system runs without interruption, though, when I reinstall OEM 512MB DIMM's (i.e., 2 x 512MB).
What might be causing this? Is there some detail of the DIMM specification that I'm misunderstanding?

Think I've gone through all of your posts- all very insightful, and alas, I have another question to add.
Want to upgrade my HP Pavillion a1050y [Intel P4 HT, 3 GHz, XP Pro, 4 slots] from the current 1GB DDR-400 MHz dual channel SDRAM (2x512).
When I look at memory for sale, most of the retailers say I have a total capacity of 3 GB RAM, however with the basic formula of 3 GB divided by 4 slots I get 750/slot. So am I limited to the 4 x 512 MB? Or is there a funky combo possibility of 2 x 1GB, and then another 2 x 512MB? Am I limited to the 400 MHz or can I go 667?
And upgrade the BIOS before proceeding.

My computer is a Compaq Presario SR2030NX. It has two memory slots with a 512MB Hynix 1RX8 PC2-4200U-444-12 in each. To upgrade, I installed a 1GB PC2-4200/533MHZ DDR2 in each slot. When Windows XP tried to start, it would get to the Welcome page and then go back to trying to start all over again.
What should I do next? I have no experience with installing RAM or with doing anything to the BIOS, but I can follow instructions fairly well.
Please help, because I must have damaged one of the original sticks, and now have only 512MB showing up in the system information. I've found some used 512MB that I can order, but I'd really like to get the 1GB's to work, if possible, or find out which other type of 1GB's would work.
Thanks,
Carolyn

I have an SR2010NX I would like to upgrade the memory on, it has 2slots each filled w/ PC2-4200 256Gb. i was thinking of getting a 2Gb stick of PC2-5300. Is this advisable? Do i have to remove both of the original sticks? Would it be better to get a 2Gb stiack of PC2-4200 and retain one of the 256Gb sticks? Any suggestions?
Thank you in advance.

Hello all have a memory upgrade question if someone can help. I have an HP d4790y that I bought around 2-3 years ago. Recently I wiped the hard drive clean and upgraded to Windows 7 32-bit. My system currently holds 2 GB of ram (2 x 1 GB of PC2 5300 at 667MHz in dual channel mode as well. My motherboard (ASUS P5BW-LA) has 4 ram slots. I am looking to upgrade to atleast 6GB by buying 2x2GB of DDR2 5300 at 667MHz and then upgrade to Windows 7 64-bit. I understand that Windows 7 64-bit needs atleast 4 GB of RAM, so how should I go ahead and install this. Should I put one stick in, upgrade to 64-bit, then put the other stick in when done? Or should I put both sticks in right away and upgrade straight to Windows 7 64-bit. Lastly will I have issues since the existing RAM is only 2 x 1GB despite it having same speed and latency. I am aware that the upgrade to 64-bit has to be a clean install so I will have everything backed up. Someone please advise because I do not want to have to pay someone like the Geek Squad to do this since it is so simple to update memory. My e-mail is drd1434@gmail.com if you want to reach me there.

I have an HP dc7800 small form factor desktop and need to upgrade the memory. Does it use 'low density', or high density' memory? I have looked at the hp memory specs but there is no mention of the low or high density specifications. Thanks

Hi lvdj1983.. First, I'm assuming the full identification of your pc is HP Pavilion t3218uk.. cause that's what comes up on the HP support site. The specs call for a total of 2-G's of DDR2 memory, meaning two sticks of 1G memory for the two slots your mobo has. Since the mobo operates at 533MHz bus speed, it makes sense (and specs call for) a memory upgrade to PC2-4200 (533 MHz) memory. I'd advise checking the web sites at major memory makers to see what specific memory they advise. I lean toward Crucial, Corsair, or Kingston.. but go with your instincts. The down side to this upgrade is the mobo only uses 2-G's total...barely enough to run Vista-32 when using the onboard video. If you haven't upgraded to a discrete video card, you may want to consider it now. Good luck.

Krusty.. you're making a simple idea more difficult! The difference between high and low memory density is whether the individual memory stick is more or less than 1-G in size. 256MB to 1G = low .... 2G to 4G = high. High density memory may also have memory chips on both sides of the stick. In your case, the DC7800 uses up to four sticks of DDR2-5300 OR 6400 memory. Although the spec sheet doesn't specify maximum total memory and maximum memory per slot, I'd bet you're looklng at a total maximum of 4-G's... or four sticks of 1G each at DDR2-6400 (800 MHz). If the machine is running a 32-bit OS, you will see all memory identified , but the OS will only use 3.3-3.5Gs. If you're running Vista Business-64, then the system will use.. and need.. all the memory. A discrete video card will also help out a lot. Good luck

drd1434... your d4790y specs say you can use 2G memory sticks in each of the four slots. You want to upgrade to W7-64 which needs a lot more than the existing 2Gs you have. According to the spec sheet, you should be able to add two sticks of 2G PC2-5300 memory for a total of 6-Gs. Make sure the latency matches!! Put all the memory in before upgrading to W7-64. I also believe you should stagger the memory sticks, i.e. 2G-slot 1, 1G-slot 2, 2G-slot 3, and 1G in slot 4. Also make sure your mobo BIOS is up to date along with drivers... and you are good to go. There is another possibility, try upgrading with just the two new sticks of 2G memory (total of 4G) and then add the two older sticks of 1G after you get the OS in and set. Good luck.
