RAM compatibility

Hi RamGuy, hope you can help.

 

I ordered this

 

https://www.komplett.ie/k/ki.aspx?sku=321028

 

When i was building my PC earlier last year, and I finally decided that I id get another 2gb for my PC. i ordered the exact same stuff, I made sure the specs were all the same. However, I installed them today and my PC is only registering 3007Mb. I have a 64Bit version of Vista, so it should be able to cope with over 3gb.

 

I noticed on the side of the chip something about a different version and I did a search of your forum and found some discouraging posts about this.

 

1.Am i damaging my Mobo with different version of RAM in? :eek:

 

2.What do i do to get the extra Gig working?:mad:

 

3.If I have to return it, what are my chances?:eek:

 

Thanks in advance for your help.

 

Edit-I have an ASUS P5b Deluxe mobo

Go into your BIOS. Go to Advanced then Northbridge Chipset Configuration. In that menu you will find Memory Remapping Feature, Enable it. Save changes and reboot your PC. Go into BIOS and check if it detects all 4GB.

 

NOTE- You may have to set AI Tuning to Manual to change that.

I tried that, the system is now picking up the extra Gb, thanks a million for your help.

 

I have just two more questions i hope you can help me with.

 

1. What exactly did i do with memory remapping?

 

2. Is there likely to be a problem between the two different editions of the RAM? Is it damaging my PC, putting it under a greater load or making it work worse than it was with 2Gb>

Thanks for all your help before, but I seem to be having some problems.

 

The PC works fine, I can play games etc, surf the net, work but since i installed the new Memory, I have gotten a BSOD (it looks different though, has a countdown at the bottom, and does a memory dump?) about 4 or 5 times? Never at strenuous times, just when logging in, or opening internet explorer, or browsing files.:confused:

 

I havent had a chance to run MEMtest yet, I will today. I think i have it on an old ubuntu cd.:laughing:

Ya, IE error easy with bad ram or wrong settings. The reason web browsers do is most the temp data is stored in ram, not hdd (not talking cookies). So when the browser (also loaded in ram) looks for the data and its corrupt or missing it will give a BSOD, the mem dump is the error data.

 

Run memtest on them. If it fails, test your new ram by itself, one stick at a time! If one is bad, rma. If both it could be your settings or mobo. It probably wouldnt hurt to check your old ram aswell.

Its seems there are more than one of you posting in this thread and its confusing me and you weather you know it or not.

What is your complete system configuration and what is the problem or error you are getting? You stated you did not get errors in memtest!;):

Hi Ramguy, I started this thread.

 

My problem is that I'm getting random BSOD's (the one with the countdown at the bottom) for no reason since i installed my second 2Gb's of RAM. I had to enable memory remapping in my BIOS to get my mobo to recognise the 4th Gb.

 

I have

 

Windows Vista 64Bit Premium.

A GTX 8800

An Intel E6600 Dual Core CPU @2.4Ghz

Asus P5B Deluxe Mobo

 

I had 2gb of this when i built the PC

 

Corsair TWIN2X 6400C4 DDR2, 2048MB CL4, Kit w/two 1GB Dimm's, E.P.P Technology

 

I went to the same link and bought the same stuff just before xmas, made sure it was the same spec etc, but when I got it, it seems that it is a different edition? Says nothing about that on the komplett website.

 

https://www.komplett.ie/k/ki.aspx?sku=321028

 

I now have 4gb.

 

The first i heard of these 'editions' is slightly different text on the side of the actual RAM stick. The new stuff says 2.1.somethinglikethat.

 

So thats my problem, hope that clears it up a bit:o:

Thanks for the help.

 

The patch part seem pretty explanatory, but i was already advised on the forum to enable memory remapping on my BIOS and that has allowed it to pick up the full 4Gb. It says so when I check my system specs. Does that mean it isnt actually working and I really do need this patch?

 

As for the other instructions, Im very unsure of what they mean and I need some advice on what exactly they will do and how they do it. Is it a risk to my PC?

 

Are these BSOD's harming my PC?

The patch will help fix the Stop errors and the size of the memory will be shown in Windows by bringing up system properties.

Can you be more specific about what you need help with?

Sorry, I will try and be clearer. At the moment, my PC is picking up the whole 4gb. Or at least it says so. Do I need to install the patch?

 

This is what I am unsure of

 

"Please make sure that you set the memory frequency at DDR667 and set the Write to Precharge Delay to 15 and I would set the memory Voltage to 2.0 Volts as well."

 

I have not heard of any of those terms before.

 

I picked the RAM upgrade over the HD upgrade because I didnt want any of the hassle I had building my PC!!

I downloaded the patch(the correct one) and it says it is not relevant to my system? It seems of the page that this patch only works when installing Vista onto a systems that already has 4Gb RAM installed, not installing extra RAM into an existing Vista system.

A: Yes if you have not done so and you have 4 Gig of memory installed!
