According to HPs information on that mainboard it should only have 2 slots and they are blue...see this link: Motherboard Specifications M2N68 LA Narra6

Is it possible you could take a picture of your mainboard and upload it?

SOURCE: i'm doing a memory upgrade. i have four memory

Try them in the same-colored slots, nearest the processor. It seems ASUS (who makes your mobo) has chosen to color code their slots so those of the same color enable dual-channel. If you can't tell from the BIOS detection, try CPU-Z to verify that the memory is in the correct slots for dual-channel operation. Putting one in the wrong slot should not damage anything. It would just make it so you can't take advantage of the extra speed.

Hello here is the homepage:

http://www.asrock.com/mb/Intel/X58%20Extreme6/?cat=Manual

I think you have a ram problem:

1. Please install the memory module into the white slot (DDR3_A1,
DDR3_B1 or DDR3_C1) for the first priority.
2. Due to Intel CPU spec definition, the system will not boot if only
one DIMM is installed into DDR3_A2, DDR3_B2 or DDR3_C2 slot.
3. Due to Intel CPU spec definition, XMP DIMMs and DDR3 2000/
1866/1600 are supported for one DIMM per channel only.
4. You may install varying memory sizes in Channel A, Channel B and
Channel C. The system maps the total size of the lower-sized
channel for the dual-channel or triple-channel configuration. Any
excess memory from the higher-sized channel is then mapped for
single-channel operation.
5. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be
damaged.

Try only with one module, in the white slot.

Hope this will help you.

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.

Info from the manual:

Memory configurations

You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into the DIMM sockets using the memory configurations in this section.

• Install only identical (the same type and size) DDR DIMM pairs

using the recommended configurations.

• Make sure that the memory frequency matches the CPU FSB

(Front Side Bus). Refer to the Memory frequency/CPU FSB

synchronization table on the next page.

• This motherboard does not support double-sided 16-bit DDR DIMMs.

• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.

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; http://support.asus.com/faq/faq.aspx?SLanguage=en-us&model=P4S800D-X&product=6&os=17

This should help you configure the memory.
Good luck!

Anyone know why an ASUS PTGD1-LA motherboard will only take memory in slots A1 and A1 or A1 and B1 but not anything in B with both in A filled? Brand new memory.


HI,

The board has specific requirements for memory. Here's the Memory Configurations :

  • You may install 256 MB. 512 MB and 1 GB unbuffered non-ECC DRR DIMMs into the DIMM sockets using the memory configurations in this section.

• Installing DDR DIMM. Other than the recommended configurations may cause memory sizing or system boot failure.

• In dual-channel configurations, install only Identical (the same type and size) DDR DIMM pairs for each channel.

• Always install DIMMs with the same CAS Latency. For optimum compatibility , It Is recommended that you obtain memory modules from the same vendor

• Double-sided x 16 modules are not supported on this motherboard.

• Due to chipset resource allocation, the system may detect less than 4 GB system memory when you installed four 1 GB memory modules.


For dual-channel configuration you may:

install identical DIMMs in all four sockets

• install identical DIMM pair in DIMM_A1 and DlMM_B1 (blue sockets) and identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)

• install same size DIMMs in DIMM_A1 and DIMM_B1 (blue sockets) and another same size pair in DIMM_A2 aid DIMM_B2 (black sockets)

Hopefully this will help understand how to install the new memory.

Thanks Mark

Your MB is AM3 with 128MB DDR3-1333 built-in, four 1.8 Volt DDR2-1200+ depending on cpu. Have you enabled cpu 64 bit extensions? Tried slowing down your memory bus?
My ASUS use dual channel for dual core cpu. I have 2 yellow and 2 black dimm sockets. Both dimms in yellow is single channel, one in yellow and one in black is dual channel. Might try 2,1,2,1 rather than 2,2,1,1 order. If only your 2 1GB dimms are seen then why do you get 4 GB from 1GB+1GB? Sounds like sockets 1,2 are giving you 4GB and 3,4 don't work? Are the 1GB+1GB in 3,4 visible if the dimms in 1,2 are removed? Per Gigabyte page your AMD Phenom II 920 is AM2+ : "Note: Due to AMD AM2+ CPU limitation, memory module DDR2 1066 or above speed is only supported by 1 dimm per channel." Per AMD (which does not show your cpu, AM3 cpu fit AM3 or AM2+ socket and support ddr2 and ddr3, AM2+ cpu only work in AM2+ socket and support ddr2 only.

As all clarification requests, you should be more specific so we can help you. Now your problem could most probably be that the third RAM you want to put does not comply for dual channel. If you want to use three DIMMs in a dual-channel configuration, install a matched pair of DIMMs equal in speed and size in DIMM 0 (blue) and DIMM 1 (black) of channel A. Install a DIMM equal in speed and total size of the DIMMs installed in channel A in either DIMM 0 or DIMM 1 of channel B. Your best bet is to have all your RAM in identical configurations of bus speed and size.

Asus K8N-dl - second processor present but not running...


Hi, Mistyman here. All Asus mother boards that have dual channel RAM slot must have equal ram in each slot. In most cases the paired slots are matched by color for easy ID, some are identified by a printed ID on the mother board. With your board you will have to have run all of your RAM for the one CPU. If you have only one stick this must be in slot one. If you are using two sticks then utilise the dual chanel system that ASUS have and use A1 & A3. To activate the second CPU you will need to install matching sticks of RAM in the B slots. both cpu's will need to have the value of RAM to work together properly. CPU one = slot A for RAM CPU two = Slot B for RAM. Goodluck, the ASUS boards are a value product.
