I have the p5e3 deluxe board, two independent ati 4870 pcie 2.0 x16
I also have memory set to 1.9v for the ocz3g16004gk 8GB of ram (native
1600, set to 1333)..
When i have just those 2 cards in the board.. cpuz reports that the
"link width" ix x4 while the max supported is x16..
Are the video cards in the two blue slots ? (The black one is x4.)
They should both be x16 if placed in the blue slots.
A better tool for checking the video cards, might be GPUZ.
The menu at the bottom allows selecting a card. Current
version 0.2.8 (I have 0.2.7 on disk here).
What is meant by link width? Does this mean i'm not getting the full
bandwidth out of my cards and likewise 3dmarks etc? (3d mark is
CPUZ and likewise memset.. report the ram as 1.5volt.. is this an
actual report of the ram volts, if not, how can i verify it is
Thanks for any help here
There is a picture of CPUZ for a P5E3 Premium here. Not the same
as your board, but illustrative. The SPD tab seems to be showing the
JEDEC standard for voltage, and I don't know if that is actually
stored in the SPD or not. I thought only the "non-standard"
standards (i.e. invented outside JEDEC) actually stored the
desired voltage setting in the SPD.
With your board, the first issue would be, is Vdimm actually
measured ? Or is it only visible as a setting, like in the
BIOS ? It may not be connected to the hardware monitor, which
has a limited number of channels.
On a P5E3 non-deluxe, this is someone's idea of how to check
Vdimm. It is possible the center pin on that MOSFET, is at
the same potential as the tab soldered to the board. That
is how the leg can be cut off by the MOSFET maker, and still
work. You can see the tiny, square regulator chip, which the
author of this picture was not able to identify. And the
code quoted in the picture "CZ-9F", is not typically useful
for lookup (when surface mount components get small
enough, a custom code is used to ID the component -
you have to know who makes it, and download a doc, to
look it up in a table). A similar looking circuit is
present on your board, near the CPU fan header. The
layout is not done exactly the same way, so you'd have
to probe more than one MOSFET to find it.
The one time I successfully measured Vdimm on a board,
I ended up probing a pin on the DIMM slot. That was easier
than trying to guess which MOSFET was doing it.
Thanks for that info.. i figured the voltage was just a reference in
as far as the pciex16 thing.. they are both in x16 slots (blue)..
I did come across one person who mentioned they had their bios pcie
rate at 100, instead of auto.. they said if they set it to 105, then
the pciex4 became x16; once i can get a vista system going again, i
will try this change and test it, as well as with the gpuz tool..
Changing the value to 105, didnt change the cpuz reading of x4..
