ASUS P4P800E-deluxe and dual channel memory

I have installed two pairs of Kingston kit memory sticks on my P4P800E-deluxe (2x1GB and 2x512GB) but the computer only shows 1.5GB. I have tried all types of different arrangements in the memory channels, but nothing works. Should I be changing something in the BIOS?
Any help you can give would be highly appreciated.

Thank you.

AGP Memory hole, in the BIOS setup, was the cause of "lost" of my 128Mbytes of memory.

Re: ASUS P4P800E-deluxe and dual channel memory

I'm not totally sure whether this would make that big of a difference or not, but the ASUS QVL for that motherboard does not list both those particular memory modules (Kingston 1GB) as being supported for double dual channels, only for single dual, or for single channels only and there is some note in the memory specifications and setup configuration about not reading all the memory due to some bridge or another, but still optimizing all the memory.

You might want to ask ASUS about it.

The manual for your motherboard states:

For dual-channel memory configuration (2), you may:

• install identical DIMMs in all four sockets OR

• install an identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow

sockets) and another identical DIMM pair in DIMM_A2 and

DIMM_B2 (black sockets)

* Always use identical DDR2 DIMM pairs for dual-channel model. For

optimum compatibility, we recommend that you obtain memory modules
from the same vendor.

Not recognizing memory.

The Asus P4S800-X MB can use Dual channel DDR memory and single channel memory. The dual channel memory which comes in matching packs. (Normally 2 DIMMS per pack) is the faster memory.
In other words if you are installing, 4- 512MB DIMMS of PC3200 all memory should be matched,
or you're MB may not see all connected DIMM'S.

See page vii in you're manual. If you're running windows XP, Home or Pro edition the bios will show up to 4GB of memory installed but windows XP 32bit will only show 3GB of memory. As mentioned above all 4 of you're 512MB of memory should be dual channel and run at the same speed. You can run both single channel and dual channel but you must follow Table 1 in you're manual. (1-9).
Example; PC3200 400MHz.
Or 4-512MB PC2700 333MHz. See page 1-9 for memory configurations and the QVL list supported.
Check out Asus FAQ's;

This should help you configure the memory.
Good luck!

Hi I have inherited an asus m2n mxse mobo with an unknown cpu in and fan,supposedly working. I have a stick of 1 gb kingston ram (DDR2-800 KVR800D2NG) in 1 slot. The board won't start, even into bios,it...

pj, the manual specifies, See page Viii and page
1-3. for the memory supported by the M2M-MX SE MB uses: Dual-channel memory. 2x240-pin DIMM up to a max of 2GB. Non-ECC 800/667/533 MHz
All dual channel memory comes in pairs. Also see page 1-13 before installing you're memory.
SS memory should be inserted into DIMM_1.
DS memory should be inserted into DIMM__1 and DIMM_2.
Provided below is Asus updated QVL list.
If you wish to install Kingston you'll need to buy,
KVR800D2NG not KVR800D2N5 as shown in the QVL list. Ran a search through Kingston’s site. Seems the memory you bought is not supportive for Asus MBs.

Dead ASUS P4P800e-deluxe motherboard. The verbal POST says ''System failed CPU test''

Try cleaning up the motherboard, remove and clean the heatsink, CPU fan, RAM, etc. Might be caused by dust that have build up inside. Hope this helps.

2G Memory Upgrade

I had similar problem with CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

If this is your RAM:
Corsair 1024MB Value Select PC2-4200 (533MHz) DDR2 RAM, 128Mx64non-ECC, 240-pin DIMM, Unbuffered, CL4, Lifetime warranty (VS1GB533D2) Then it is high density. You need low density to work, look for one ending with an 8, not 64.

Motherboard Missing instruction manual for dual mode memory

Your instruction manual for the mother board should have this, however, with dual-channel motherboards, you will want to fill the same colored slots together if you have dual-channel capable memory, otherwise you'll want to fill in the off-colored slots first.  ASUS has it's manuals online, so if you've lost yours you should be able to download a pdf of it from their website.
