Hi!

I see the difference between boards is that the HJ054 supports using a
pentium D.

Well, you're doing better than I would have thus far. I don't know that
board very well and have not researched it.

As far as finding a power supply tester, I've located a few online but I
have not found one that still reads -5V for the older board systems.
Any suggestions.

You need only a piece of scrap wire, possibly some older hard drives and a
cheap multimeter to test a computer power supply. The scrap wire is used to
ground the green wire in the motherboard power connector (connect it to a
black wire). There is very little danger in doing this, as you are only
dealing with a low voltage (5 volt) source.

Since some power supplies need a minimum load to work properly (although
this is pretty rare), that is where the old hard drives come in. They should
be ones that you won't mind losing if the power supply is bad.

The voltmeter (need not be expensive, just relatively accurate) will tell
you what all the power supply voltages are doing. This is better than what a
lot of load testers do, as many of the ones I have seen only turn on an LED.

In a system as new as the Dimension E series, I'd be rather surprised if you
found a -5V line anywhere. Having a -5V line hasn't been required in the
ATX/BTX power specification since the early 2000s. Even so, a few power
supplies still have one.

Ok I have a hj054 MB on order. I need some help in understanding the
best choice for a cpu. This board is supposed to handle a pentium D
dual core. So what exactly does this mean as far as choices? It says
it has a 945G chip.

According to Intel's web site, the 945G chipset supports the Core 2 Duo
CPU, as the fastest, bestest and baddest CPU you can install.

So is core 2 duo the same as pentium D, or is it different? I'm
guessing the biggest and baddest pentium D also means the HOTTEST.

Ok, I see pentium D and core 2 are different. From what I'm reading,
core 2 will work on the e-520 series and not e-510.

I just recieved a Pentium D 940 3.2 GHz/4M/800 SL94Q, but it does not
boot. I have the HJ054 motherboard in the e510 with the A07 bios so I
was hoping it would work. I just get an orange light at the front
power button and a brief light at the keyboard showing an attempt to
boot but no video. Does anyone know if any pentium D will work or just
certain series of pentium D's will work?

I received another Pentium D SL95W from the place that sold me the
board (dell E510, HJ054 board) and it works great. Here is a site for
the specs of that chip…
http://www.cpu-world.com/sspec/SL/SL95W.html

and the chip that would not work…(SL94Q)
http://www.cpu-world.com/sspec/SL/SL94Q.html

The SL95W has C1 stepping, the SL94Q has B1 stepping. What does this
mean? Is there any reason that a SL94Q would not work?

Hi!

of pentium D's will work?

Only certain series are supported. It would be the most helpful to get
a list of the processors that Dell offered during that computer's
production run. I don't know of any such lists, however. Another
fairly safe bet is to choose from processors that were marketed during
the time that computer was made, with specs that come close to the
ones Dell offered (chips with an 800MHz FSB and LGA775 socket, for
example).

The Core/Core2 Duo chips have almost nothing in common with the
Pentium 4. Intel threw out all of the Pentium 4 stuff when they
realized how far out of control the TDP of higher end chips was
getting and that sheer clock speed increases were not the solution.
They went back to the Pentium M for inspiration. The Pentium M was
based on the Pentium III.

mc

What do the specs for this processor say, and how do things like the
FSB speed and core voltage compare to the CPU that does work?

An orange light in the power button can mean that there is a problem
with the CPU's power supply.

The system BIOS must also support the CPU. Upgrading to the latest
Dell supplied BIOS *may* resolve this, although there are no
guarantees.

I wish I understood more, I only know that the B1 stepping came out
before the C1 stepping, so I would think either would work.

Neither Dell nor any of the other major name brands ever provides
externally visible information explaining which CPUs work in their systems.

At least give Intel some credit for providing some minimal info about
CPUs supported in its motherboards. Even then, the info provided by
Intel is not at all comprehensive, as I have found newer CPUs to work
sometimes in Intel mobos. This usually happens when Intel releases a
CPU after the mobo specs have been published. In more recent years,
Intel provides fewer and fewer addenda to its motherboard specs.

Motherboard chipset specs often provide the best information as to which
CPUs are supported by the motherboard itself, except that the mobo BIOS
may be more restrictive.

So you get another CPU to try and it is all a crapshoot... Ben Myers
