Single Processor on a Dual Processor Motherboard

I am on the verge of buying a dual processor motherboard EPOX EP-D3VA, however initially I wish only to use one pros as I cannot afford a second one immediately. Can the motherboard work with only one pros or do both have to be installed?

I am also considering using an Asus V7100/dual display GeoForceMX card, any potential problems with that?

thanks forcesho

does a terminator card come delivered with the MB or do I have to buy one (if so how much does one cost)?

The terminator card usually comes with the motherboard.

Not sure about that particular board, but my Tyan Tiger 100 did not require a terminator card. I ran a single processor for a month or so.

No I use it as my server with dual P3 500's and 324 mb memory. Nice little home server.

I have an abit BX6 dual processor motherboard and I only run one processor without a terminator and I mine runs very stable. I have been running this system for over a year now.

An Abit BX6 is not a dual processor motherboard.

What EVER you do, do NOT take an NT4-installed HD from a dual-CPU machine (even if it one has one CPU and a terminator) and expect it to work in a single-CPU box.

NEGATIVE. NO-GO. NOT GONNA HAPPEN.

Let's just say I learned the hard way. :/

Though this is an old thread, I found it after a search.


I have a similar situation. I plan an ASUS Z9PE-D16 (dual-2011 sockets) server board starting with only one Intel E5-2687W in one socket with.


Then I ran across another forum post stating that only one CPU installed on a dual board will compromise the memory bandwidth, the QPI bandwidth, and other functions. The person posting this sounded very knowledgeable and credible; that is, his other claims I personally knew to be true. Though he made no mention of a terminator card. But this "compromising bandwidth" in a single CPU on dual board, I'm not sure about.


Help please. Thanks.

It might be more useful to post a relevant quote from this source along with your own questions in a new thread, not one that is over a decade old!

You dont need a terminator card for that platform. Silly to use a 12 year old reference for technology. And no, one CPU will work perfectly fine without any penalty.

The potential memory bandwidth will be halved, and the QPI bandwidth will be gone. However, QPI only exists to connect the two sockets together in an efficient manner in the first place ;) And you will still have the same memory bandwidth per-core, which is the important metric (and you won't have the sometimes unpredictable latencies of a NUMA setup). Just make sure you connect your RAM and PCIe cards to the right processor socket!

The manual for that motherboard is available for free from ASUS' website- download it and read through it to clear up any confusion you have before you go ahead with building the system.

Good luck! :thumbsup:

If you go back to some of the old Intel® Xeon® DP or MP processors (NetBurst®) you might need to use a voltage regulator in a socket that wasnt being use but nothing today that I know will use one.
