Dual chanel problem

First problem - I cant get my 512mb sticks to work dual chanel - pc reboots before the system loads up.
Second problem - if I put four 512mb sticks (all same specs) at the same time I have a black screen and a beeping pc.
What to do, what to do?

    It seems, that one of the slots on the board is broken, since the pc crashes whenever I try to put any stick in that vary slot :/

The beeps your hearing are known as bios beeps. They are telling you there is a problem with your memory. On your board the four dimm slots are split into two groups. A & B. Pg. 19 of your manual. Please read Pg. 21. Remove all your memory & put only two of your 512 Dimms into slot 1 & slot 3. Boot the Pc. Notice any beeps? Check your boot screen to see if bios sees the current memory as matched memory. Shut the Pc down & remove memory, replace with the other 2 Dimms in the same slots. Boot Pc. Again check to see if memory is being seen as matched memory & no beeps. Are you getting the idea here. What we are doing is trying to find which if any dimms may have a problem & which dimms work in which channel. Increase in size to 3 dimms or 1.5Gb in memory till you find a working order with no beeps. If you think 1 or more dimms may be faulty download a free test program called -Memtest86 at this link.
http://www.memtest.org/ Scroll down till you see - ** Memtest86+ V1.70 (01/14/2007) ** all typed in red. Here you can choose what type of bootable file you want. An iso or a zip. You can creat a bootable floppy or a bootable CD.
This should help. If you have trouble & need more information please post back.

    I do not doubt your conclusion but if you take a very strong flash light & include the help of a magnifying glass you can double check that slot for any bent copper connectors. You may even find some lint or dust built up deep within. Take a lint free cloth & add a wee bit of Alcohol & wipe down the copper leads on the dimm. Than do the same with a cotton swab into the slot. Blast it dry with some canned air. Make sure both dimms & slot is dry before reinserting memory. Try again. This may help!

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!

If I unstall DDR400 memory as as follows: DDR1 & DDR3 : 512MB each DDR2 & DDR4 : 256MB each making 1.5 GB in total, will dual channel technology be activated?


Definitely not. Dual channel technology requires that the 2 RAM modules installed in each bank be of the same capacity, data rate, & even better be from the same manufacturer.

Memory confusion different readings


It sounds like something isnt working right, what operating system are you using, Vista? I would take out the original 512 and see what it says after, often ram isnt compatible if it is too different in size and speeds. Also, if your motherboard supports dual channel ram and you have the extra 512 chip it wont run in dual channel mode, you would run better with just the 2 chips then the added 512 chip.

EPoX EP-8RDA+ Pro problem with memory


First try setting your memory voltage in the motherboard bios to 2.5volts if you haven't already and you might try different timings in the bios also for example 3-3-3-8. If that doesn't work try taking out one of the modules and testing them each by themselves in the memory slots of your motherboard. It may take awhile, but you'll rule out the memory slots causing the problem. One of the memory sticks could be faulty. Hope this helps.

Restart problem


Hi mewada,

If the system is rebooting itself, it may not be an issue with the drivers - there may be a hardware issue or an improperly seated CPU fan or other peripheral.

I'm not sure from your problem description whether you're able to get into Windows at all - does it just randomly reboot, or does it Blue Screen and never let you in at all?

If you're able to get into Windows and it reboots now and then, try installing the proper CPU drivers. For many games and some other applications, dual-core AMD CPUs require a specific driver. There's also a dual-core optimizer you may want to try. Check at the top of this list.

http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_13118,00.html

Otherwise, please be more descript as to when the system reboots and (if you know) what you think you might be doing when it reboots. Faulty memory (RAM) modules and CPUs are the main causes of systems rebooting (other things are generally at fault for freezing up or blue screens).

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.

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.
