I have purchased 2 x samsung chip 1 GB ddr-400 PC3200 184 pin chips to up grade my ram on my hp pavallion t680a. I installed these and my system seemed to reconigise the fact that the ram had been increased to 2 GB - but I had a number of problems where my system closed down (giving a blue warning screen with various codes each time). I also ran a PC Doctor Diagnostic and an error came up "memory advanced patern test = me516-5". It appears that the Samsung chips are the correct type - but do not seem to be compatatable. Is there some sort of BIOS patch I need to install for the ram upgrade to work or are the Samsung Chips not compatatable with the HP machine? THANKS!!!!!

2x 1 GB DDR 266

That
is a socket 754 motherboard. It will support AMD Athlon processors up to Athlon64 3400+. It is a bit long in the tooth by today's standards, and only uses DDR memory, not DDR2. You may get more of a bang for your buck by buying a "barebones" system, which can consist of a motherboard with processor and memory, depending on how much you want in the barebones package.

Typically you use the case, power supply you already have with the new motherboard and processor and ram (memory).

At any rate, if you only want to upgrade your processor, keep in mind that your board only supports up to the Athlon64 3400+. It will support up to DDR 400 ram. You would probably benefit more by buying 2 sticks of 400 DDR ram at 2 gigs each, if you don't have much ram now. If your processor is close to the 3400+, then another processor in that board isn't going to change things much.

Good luck, and write back if you'd like more help.

Socket754 Supports AMD Athlon64 upto 3400+;

The 6735s requires DDR2 SODIMM chips clocked at 800 MHz and they must be installed two at a time (so a 2 Gb chip won't work - you need 2 1 Gb chips. Installing 2 + 1 Gbs will give you 2 Gbs only, (1+1), that is if the PC even boots at all; and so on).

Also, not all operative systems will read the full amount of RAM installed.

Yes. That motherboard can handle a total of 2048 (2 GB) of DDR PC 3200 (AKA DDR 400).

Best and easiest thing to do is go to www.crucial.com and run a scan of your computer. It will tell you what you have, how much it will hold, and what kind of modules.

Yes, it's safe.

Thanks for using Fixya!

the machine uses ddr 1 memory and hold a max of 2 gb of ram


RAM 128/2700 MB DDR SDRAM
Maximum 2 GB (2x1024MB DDR SDRAM)
Sockets Two 184-pin DDR DIMMs
Size 128, 256, 512 and 1024 MB DDR DIMMs

the motherboard is a socket 478 board , the Dual-Core chips are socket 775 so you couldnt use them unless you change the motherboard

the model SR1010NX can take upto 1gb max of ddr 1 ram and must be done a 2x 512 ddr 1 chips

Hi giovanni2,
Sorry but you're board does not support DDR2 memory.
Only 2 x 184-pin DIMM sockets support two 2.5V DDR SDRAMs (DDR400/333/266). There are two PC Chips M871G.
One is M871G (V1.5) & the other is M871G (V3.1). Neither support DDR2 memory. DDR2 memory used DIMM slots with 240-pin. The memory slots on you're board uses 184-pin. The board will not function with 240-pin memory.

need low densisty on ebay 35 buck eash 1 gb ok works on picky mobos way better

Hi,

the memory you're about to purchase will not work. the maximum gig that the computer can handle per stick is only 1 gig. this system is not designed for 4 gig barrier.

hope this helps.

thanks.
