Does the Intel MB DG41TX work with the Intel 7300 processor and a single 4GB memory module (Kingston KVR1333D3N9/4G)?

First, your pc5300 memory runs default at 6300Mhz, not 333. Perhaps your motherboard Front Side Bus line is 333 in which case the memory will drop to that speed, but if the FSB and memory match speed, then it would run at 6300. Since you have an older unit, I would suppose you are running only 333, and that is average speed for that config. In addition, you are only running 1 gig RAM, which is woefully inadequate for Windows 7, so everything you do is going to be slow.

Yes, with one you will not run in dual channel mode but, depending on what you are doing,may not notice any difference.

sad how, how fixya AI guessing wrong??? pathetic, mess....
wow a very old media center, gen 2 of 14 or so.
HP does not support this quote
HP Media Center m1070n Desktop PC,its RETIRED now
https://support.hp.com/us-en/retired-products


The BIOS does not do that!
what HP, it has full name and model.
the MMC controls this, and is very strict. (mem-managment controller)
the memory you are buying is no good. for YOUR PC.
this is so very common
and worse every year,
ever heard of Crucial or Kingston memory
they can fit up memory for you, it very complex.
not just DMM1, 2,3, but speed, min.
density rules.
chip count rules
chip voltage, 1.3. 1.5 or both or?
Total memory max allowed and PER SOCKET !
and even number of chips per side of stick , rule.
that worst was intel i5 old processors.
those are facts, and only the exact motherboard you have a
and what processor is there, (and if mmc is external to processor that)
matter.
? this?
M1070n

finding data on such and old box.
is not easy but google can dig up bits.
why not ask Kingston? for help,.

key facts are, (besides old)
HP Media Center m1070n Desktop PC
Intel Pentium 4 520 / 2.8 GHz
Intel 915P Express (my guess, mmc is inside here)
oops

• 512 MB / 4 GB (max)
• Memory Speed 400 MHz
• Memory Specification Compliance
  PC3200
• Features
  unbuffered
• Configuration Features
  2 x 256 MB
• Technology
  DDR SDRAM
• Installed Size
  512 MB
• Data Integrity Check
  non-ECC
  
• 4 GB
• Form Factor
  DIMM 184-pin

looks like 1GB max per slot , 1 to 4.
good luck finding SDRAM in 2017 that works.

why not find a newer box? (pc) say 2010 or newer.,
they will run better and can buy ram easy
vastly better.... even Goodwill has them for few bucks
or this.
or like this,

The POST beep code - 3 short beeps mean RAM failure.
Try reseating the RAM modules.
If this does not solve your problem then remove all the RAM modules and insert one RAM module at a time into memory slot 0 (1st memory slot) to determine which is the faulty RAM module.

Yes you can.
For 512 Mb RAM you can use a single 512 Mb memory module or two 256 Mb memory modules.
For 1 Gb RAM you can use a single 1 Gb memory module or two 512 Mb memory modules.

The Intel® Server Board S875WP1-E supports both ECC and Non ECC Unbuffered PC2100 (266 MHz), PC2700 (333 MHz), or PC3200 (400 MHz) compliant Double Data Rate (DDR) memory modules. Dual channel memory functionality requires two DIMM modules installed into DIMM sockets 1A & 1B, and then DIMM sockets 2A & 2B. The DIMM module size, speed and vendor must be the same.

You can install a single 128 MB memory module into DIMM socket 1A. The minimum supported memory size is 128 MB. The minimum main memory configuration is a single 128 MB memory module, and the maximum configurable memory size is 4GB. With only a single memory module installed, the system will only operate using a one memory channel.
Third party memory vendors may use the same module part number with different
DRAM vendors and die revisions. To insure proper system operation, verify that each DRAM
vendor and die revision has been separately tested and qualified. Please notify CMTL if there is a discrepancy.

512 MB of DDR2 533 MHz system memory, upgradeable to 2 GB using two soDIMM modules (dual-channel support)

Yes its possible
Yes but the memory its going to run at slow speed 533Mhz

yes one will be for single channel ram the other for daul channel ram.if you have the acer owners manual it will tell witch ones are single and witch one is daul.

If new processor supports your old motherboard then you will upgrade system with your old motherboard.

If its not supported to new mother board then you have to buy new motherboard to upgrade your system.

Thanks.
Happy to help you.

I would venture to say one of the memory modules you have is bad..
