Hi,
Using vista 32 bit with gskill ddr2 667 2 times 1 gig sticks

mobo=M2N4-SLI asus http://www.asus.com/products.aspx?modelmenu=1&model=1266&l1=3&l2=101&l3=323

Just brought another 2 sticks of identical ram, so 4 gig in total.

Specification
Capacity	512MB (512MB x 1) / 1GB (1GB x 1)
Speed	667MHz DDR2 (PC2-5300)
CAS Latency	CL 5-5-5-15
Test Voltage	1.8 Volts
PCB	6 Layers PCB
Registered/Unbuffered	Unbuffered
Error Checking	Non-ECC
Type	240-pin DIMM
Warranty	Lifetime

I get the memory beeping error when booting. Take out the new ram and it boots no issues.

I have the lastest bios from asus.

I have customised the bios settings from auto to 667 ram and 1.8 volt.

Any suggestions or questions I may have missed out

Regards
Malcolm

Umm, did you try not changing anything?

Also, trying swapping all of the sticks around. This way you can eliminate RAM slots and RAM. It may just be one stick?

You could try running a memory testing tool to see which stick is faulty. And if it is one of your new sticks, then send it back and get it replaced.

From here: http://tinyurl.com/2jnyyc

"Windows XP Professional 32-bit is limited to 4GB of address space. If you have 4GB of RAM installed, it will not show 4GB within Windows. What you'll probably get is the size of your pagefile subtracted from the 4GB.

Some of this address space is reserved for hardware and the OS... so you'll never have access to the full 4GB anyway. If you want to access 4GB+ of RAM... your best solution is to pick up XP Pro 64-bit... but that will only work if your P4 CPU has EMT64."

I had the same problem, I just took out one, so I'm running on 3 gigs until I change my OS, which won't be for a while, but I don't think I'll notice any difference until then anyway, 4 gigs is overkill at the moment. Since you're happily using Vista anyway, you may want to consider switching to Vista 64 bit (if you have a 64 bit CPU), which will fix the problem. I'm still using WinXP 32 bit myself.

The good news is, none of your hardware is faulty.

I c urrently have 2GB of ram in my PC if i were to get another 2GB stick will this problem occur to me and is it best to just get another 1gb isntead? I have Windows Vista ultimate 32-bit so will it handle having exactly 4gb of ram?

It would happen, so if you want more RAM then you should just get 1GB or hold out until you update your OS. All 32 bit OS's have this problem, by their very nature.

This cannot be correct, because the system memory beep error occurs before the windows operating system start.

Infact, this error beep is occuring before the HDD has been detected!

rscole86 is on the right track. Try your new ram only in both sets of dual channel slots. Then try the old ram only in both the dual channel slots.

Worst case scenario, the newer ram is from a new batch of ram, and for some reason conflicting with the original batch of ram (even though they are from the same brand/make).

Ever so slightly off topic, I've got some second hand RDRAM incoming: anyone know a good program to test it out, check it for bad sectors or the equivalent? I've heard memtest is all right. (and no I don't mean something like Crysis)

You can use memtest or Windows memory diagnostic tool.
