Abit AI7 + 4GB BH-5 testing vdimm per dimm slot ?

Been doing some BH-5 memory tests on AI7 and different dimm slots are producing different max oc's. I was wondering if there are any devices that can measure what each individual dimm slot supplies in vdimm voltage ?

Would such a precise measurement been capable of being provided by motherboard/bios manufacturers ? For example to make a device shapped with a memory stick dimensions with LED display to plug into a dimm slot and read the voltage being supplied to that slot ? Or to display an overall vdimm and individual dimm slot voltage in bios ?

vdimm:
slot 1 vdimm:
slot 2 vdimm:
slot 3 vdimm:
slot 4 vdimm:

To illustrate with Abit AI7 and memtest86 test #5, #6 loops

2x 512MB OCZ PC3500 Platinum LE DC
6x 512MB Corsair XMS3500C2
===============

2-2-2-6 at 3.2vdimm and 1.65v vAGP
GAT all AUTO

2x 512MB OCZ PC3500 Plat LE DC
dimm slot 1+3 = max oc 225-233mhz
dimm slot 2+4 = max 240mhz

individual XMS3500C2 tested

batch number = max oc in dimm slot 2
stick #1 - 024117 dull black heatspreader = 240mhz
stick #2 - 024117 dull black heatspreader = 240mhz
stick #3 - 0337061 dull black heatspreader = 245mhz
stick #4 - 031125 shiny black heatspreader = 240mhz
stick #5 - 031125 dull black heatspreader = 245mhz
stick #6 - 031125 dull black heatspreader = 228mhz stick #6 031125 can do 250mhz 2-3-2-6 at 3.2v fine though in dimm slot 2, same result in dimm slot 4 <--

- stick #6 errors 1st pass of test #5 at >228mhz in slots 2, and 4
- but in dimm slot 3 stick #6 - 031125 dull black heatspreader = instead of 228mhz error out on 1st, it can do 245mhz error out on 5th pass

dimm slot 3 is slightly better for this 6th stick of xms3500c2 which seems to be okay @ 240mhz 2-2-2-6 instead of 228mhz 2-2-2-6
