Ram compatibility

I have been desperately trying to upgrade the RAM on my PC for a while now without success. I have an Emachines 5260 which already has 2 sets of 256mb ram installed in 2 of the 4 slots. I am trying to upgrade to 1GB of ram so I purchased a 512mb ram chip. Upon installing it my PC would either not start up, or would reset itself after a minute or two. No matter which way I configured the rams in the 4 slots, I could not get my PC to operate. I tried the new 512mb ram in my PC by itself and still would not work leading me to believe it was faulty. I sent it back to the company I obtained it from who tested it and said it was fine. I sent them details of my motherboard and they then sent me a Kingston Ram which they said should be compatible with my PC. I installed it and I had the same result as before. Either wouldnt start up or would keep resetting. So the company admitted defeat and refunded my money. But I am still no further forward and need to upgrade my Ram. Does anyone out there know which make and model of RAM I need for my PC. I have included as much info as I think is required.

Manufacturer : eMachines
Mainboard : Intel D915GAG
Chipset : Intel i915GL
Processor : Intel Pentium 4 515 @ 2933 MHz
Physical Memory : 512 MB (2 x 256 DDR-SDRAM )
Video Card : Intel Corporation 82915G/GV/GL, 82910GL Integrated Graphics Device
Hard Disk : WDC (250 GB)
DVD-Rom Drive : DC2012A GQP753A SCSI CdRom Device

The two Rams I have tried without success were both DDR-SDRAM. Please can anyone help me. Its costing me time and money and its driving me crazy.

The memory you need is 184-Pin PC3200 (400MHz) DIMM. Are you sure that this is what you have been buying? Also best to install in matched pairs I think so if you want 1Gb, go for 2 x 512 or 4 x 256.

Kind regards

Thanks for the quick response guys. Wasnt expecting that. Jasper, the two I have already tried were 184 pin 400hz DIMM, but not sure what the PC number was on them. Like I said, I have returned them to the company I purchased them from so cant check that now.
Gardener - Thanks for the website link but they don't have my PC model on there. It's a common problem I have on web sites. My PC doesn't seem to exist.

If you know the make of your motherboard then you can enter it on the Crucial web site and it will find the suitable RAM.

cpu-z click here

Make a note of the memory listed and post back here.

PS did you clear the cmos before you installed the new ram?

  paul€ 14:52 24 Jan 2008

You need DDR333 because your cpu is running at 533Mhz. DDR400 will only work with a 800Mhz cpu.

Check with cpu-z that you have DDR333 in your machine and then just buy that to upgrade.

I have run cpu-z and this is what came up for the memory. I do not know what you mean by "clearing the cmos". Im not that knowledgable when it comes to PC terms im afraid.

Type DDR
Channels# Dual
size 512mb

DRAM Frequency 133.3 MHz
CAS# Latency (CL) 3.0 clocks
RAS# to CAS# Delay (tRCD) 3 clocks
RAS# Precharge (tRP) 3 clocks
Cycle Time (tRAS) 8 clocks

Here is what intel say is compatible RAM for your board

Thanks for all your help everyone. So it looks like the muppets at ORCA have been sending me the wrong module each time. Theyve been sending me 400hz when I need 333hz.

  dave5150 15:46 24 Jan 2008

I have forwarded the Intel weblink to ORCA who I purchased the Rams from in an attempt to shame them with their lack of knowledge.
