DFI+WInbound owners help!

Ok I have no idea why this is happening. I recently switched back from the 5 rail on the vdimm to the 3 rail and my ram is sucking like crazy. I have it at 3.2+.03 volts and it can only pass memtest5 at 237 2-2-2-6. When I switch to the 5rail it can go to 245 at 2-2-2-6. This is very wierd. Is my 3.3 rail seriously undervolting? I see it as 3.2 on the bios..... I do not have acess to a multimeter so anyone who get less of an oc using the 3.3 rail please say so so I know I'm not alone.

Did you try default voltages?

 

[Hacp]

Default voltages?? At default voltages I cant overclock at all....

Well, just keep it at the 5 volt rail, why change?

Cause of cold boot issues. I'm afraid that if I have a power outage, my ram will fry on me. I can't do that Vdimm mod with the DFI because I'll void my warrenty if I open My PSU and try to adjust the rails.

Well, when you are overclocking you voided the warranty anyway. And that is also a risk you should be willing to take. If you are not accepting the risk of ruining some equipment and voiding warranty's and having to go spend more money, than you shouldnt be overclocking.

Where do you have to open your power supply to use the jumper mod? Just move the default jumper down one set of pins in the 1-2 position, and add a spare 2 pin jumper to the two pins above the default jumper in the 2-3 position. Not too hard

Make sure you are using the yellow slots, and that you have the 6/23-2 BIOS, which can be found here:

You might also want to set JP17 to the 2-3 position to enable raising the RAM voltage over 3.2. Just remember to set the CPU voltage to something other than auto before you do it.

That looks like a custom modded BIOS, how is it? It is buggy as all hell, or does it work really well?

No, it's actually not custom. Currently, the 6/23 bios is the latest official bios, but it's only the -3 version, which may be good for TCCD ram, but it sucks for BH-5. -2 is best to use with BH-5 and is generally the most stable of the three. -1 is for generic/value ram.
