Official ASUS X38 Boards: P5E, P5E3 - Info/BIOS Thread

[Envydia007]

Guys, the board is NOT overvolting RAM. AI Suite is wrong, and I'll tell you why

Let's see the different steps we have in BIOS to enter vDimm:

1.80 1.82 1.84 1.86 1.88 1.90 1.92 1.94 1.96 1.98 2.00 etc.

Now let's see what are the steps "available" in AISuite:

1.80 1.85 1.90 1.95 2.00 2.05 2.10 2.15 2.20 2.25 2.30 etc.



So, when you put them closer...

1.80 1.82 1.84 1.86 1.88 1.90 1.92 1.94 1.96 1.98 2.00 etc.

1.80 1.85 1.90 1.95 2.00 2.05 2.10 2.15 2.20 2.25 2.30 etc.

When you select 1.82v in BIOS, AISuite will show 1.85v. If you use 2.00v, it will show 2.30v. Try it with the actual voltage you have selected in BIOS, count the steps in BIOS and then count the steps in AISuite. You'll see that they are the same! So AISuite is not reading vDimm correctly. Also, with the measure point Cranox has posted before, I can confirm this. With 1.80v in BIOS, the actual vDimm is 1.82v. With 2.00, it's 2.03v REAL.

So you can now blame AISuite, the problem is not the board. Very good Asus

Nice work man, so you are saying I am actually undervolting my RAM? Its rated 2.2 and I set it in bios at 1.96. Lol!

Use a DMM if you want to see it yourself

Also, can you tell me how does the board read the vDimm? It does not have a chip that does that function. That's one of the differences between the P5E and the Maximus. AISuite just can't read vDimm, because even the board can't know that, caused by the lack of the sensor chip. So the program looks at the BIOS, it see the number of steps you have varied the vDimm from 1.80v and puts them in its own list, showing wrong values.

The only way to read vDimm from the P5E is with a DMM. No sensor chip = no possible software monitoring.

So were does one measure V-dimm voltage at on this board??? Pics please???
