I installed recently 2 ram modules Kingston 2GB CL5 (4 GB total). The problem is that in BIOS it only detects 2 GB (1 GB for each one), I mean, half of real memory. Rams are OK ´cause I could test them before in another computer, so when I install it into my motherboar it´s only detected 2 GB. Dual channel is detected correctly so i´d like what happens.
I called to my motherboard provider so he told me they have had too many problems installing ram modules into asrock motherboards, so I wondered and said that kingston is not a vulgar trademark so he reiterated to me the problem is in ram assembly (?¿?¿?) and asrock would say "this is an incompatibility of ram" (I don´t believe this at all).
P.S.: I updated my Bios to the 2.20 version and the same results than before. Ram modules are KVR800D2N5K2/2G each one. I run windows xp (this is not important) so I´m tire to check the Bios with no result.

Yes, it would be best to take the old RAM out.
I am assuming that this is 1 stick totalling 2GB. Optimally it would be good to have 2 x 1GB modules totaling 2GB, so they could work together. Otherwise, yes, just remove the the old ram and install the new module.
If you are running a 32bit operating system, 3GB is all the system can use anyway.
Hope this helps!
From what I can tell the Dell Precision Workstation 670 does support over 4GB of RAM. However when you have over 4GB of RAM installed in the system you have to have the Memory Cooling Shroud connected to keep the memory cool. Also this is only shipped out when the system is ordered with over 4GB of RAM originally. If you do not have this part you can order it from Dell buy calling 877-671-3355.
Let me know if you have any more problems or questions
Your laptop's RAM is upgradeable to up to 4 GB using two DDR2 533/667 MHz SODIMM modules.
So your upgrade options here are: 1. Buy a 1 GB DDR2 533/667 MHz SODIMM module & install it to get a total RAM of 2 GB (Price around US$ 25). 2. Buy a 2 GB DDR2 533/667 MHz SODIMM module & install it to get a total RAM of 3 GB (Price around US$ 45).
From the information you sent, I can't figure out the exact make & model of your motherboard, but I would guess that it supports a maximum of 2 GB of RAM. So, I would suggst you try to install 2 RAM modules, each of them 1 GB in capacity & see if this works. From my previous experience, most motherboards with only 2 slots for RAM modules support only a maximum of 2 GB RAM total.
1.Make sure you have purchased and installed the correct memory .A check of the spec. lists 667 MHZ DDR2 SDRAM
2. If you have try to reset it in the laptop.
BIOS should be OK specs indicate you can increase up to 4 Gigs.Good Luck.
I had the same issue on this board where it came with a Samsung 512 MB 533 MHz PC2-4200 DDR2 DIMM. I put in a 1 GB Kingston with the same specs (533 MHz PC2-4200 DDR2) and it would not recongize the Samsung anymore with the system reading as 1 GB of RAM instead of 1.5 GB. Tried every configuration and would only see the Kingston. It would only see the Samsung if I pulled out the Kingston regarless of the slots I use. So, I just bought the exact same make/model of Kingston and it recognized that fine and the system now has 2 GB of memory (max this board allows). And, I had already installed the latest BIOS for this board from Intel before doing all this so wasn't an old BIOS. I'm figuring the board didn't like something about the Samsung memory (speed, module configuration, etc.) that made it not play nice with the Kingston. If interested I bought the DM8400A/1G Kingston modules. And, this board appears not to support dual channel memory. Only has channel A, slots 0 and 1, and I read need two channels to support dual channel (seems obvious). Boards that supports dual channel memory normally have 4 memory slots, two for channel A and two for channel B, then put in matching modules in slot 0 for channel A and B and have dual channel memory access. And if want more ram, then matching modules in slot 1 for channel A and B.
More people should complain with Asus support. Checking Asus forums, you'll find there's an obvious problem with a PCI-E video addon + 2 used memory slots. In my case, I had 2Gb (1 + 1), mb with bios version 1104, and it worked fine; when I installed a new PCI-E card, the system was very... very sluggish. Now I have uninstalled 1 memory, I'm using only 1Gb of RAM with the PCI-E card, and it's working well.
Again: checking Asus forum, this is a reported problem, and a bios bug... Asus should release a new bios version, but they seem not to bother, as this is a relatively "old' mb...
