I've never installled 8GB of RAM on a computer before and was wondering if there was some kind of setup I had to do before installing it.

I have the Intel DG33TL motherboard and it supports up to 8GB of RAM, but it isn't working. I have the latest BIOS updates, but when I installed 6 or 8GB of RAM I get the memory beep code error.

Any help is appreciated. Thanks

A focused, DG33TL‑specific troubleshooting checklist that complements the replies already here.

Start with a single‑DIMM boot test. Remove all modules and try one DIMM at a time in the Channel A, DIMM 0 (blue) socket; repeat for every stick and every slot. The DG33TL product guide shows the DIMM‑0 population order and advises using matched pairs for dual‑channel operation. (manualslib.com)

Listen to the POST beeps and follow the board table. The manual’s beep table maps a 3‑beep pattern to “no memory” (POST can’t find usable DIMMs) and lists SPD/channel warnings you’ll see on screen if a module is unsupported or mismatched. If a single stick fails to let the board POST, that stick or that slot is the usual culprit. (manualslib.com)

Confirm module type and pairing. The DG33TL expects unbuffered DDR2 (1.8V), and certain double‑sided/x16 organizations aren’t supported—mixing unsupported DIMMs or speeds will cause POST failures or SPD errors; install equal capacities in each channel for best stability. If you’re unsure which DIMMs are correct, check the technical specification before continuing. (manualslib.com)

Use a bootable memory tester and isolate faulty parts. Create a MemTest86 / Memtest86+ USB stick and run a full pass on each DIMM individually; repeated errors identify bad modules. If all sticks test clean alone but fail when combined, swap slots to identify a bad slot or suspect the board. Before replacing hardware, try clearing CMOS (jumper/BIOS reset), reseating CPU and power connectors, then retest. (memtest.org)

If these steps don’t resolve it, note which stick/slot always fails and try a known‑good DIMM from another system; persistent slot failures point at the board and may require RMA or replacement.

Hello everyone,

I have a similar problem. I'm pretty sure that I have installed 8 GB of RAM in my computer.

I use Windows Vista Ultimate 1.0, and Control Panel > System tells me that I have 3007 MB of Memory.

What has gone wrong? What shall I do?

Sorry for the delay.

x86 (32bit) operating system are limited to 4Gb of memory (3.5Gb RAM + 500Mb Other memory)
x64 (64bit) operating system do not have this limit problem and will address all of your RAM


If you have a retail copy of Vista you can order a x64 disk from Microsoft
Your current serial key will still work

To order the media (DVD) go to http://www.microsoft.com/windowsvista/1033/ordermedia
You should only pay the postage as you already have a license.
