DFI LP UT X58-T3EH8 - First bench, bios screens etc

[cstkl1]

Well i had a DMM soldered to the mobo read out points for 2 weeks. Was satisfied with the stability of the voltages.
They are perfect

What i was trying to point out was symptoms of a bios corruption
The reason being its kindda hard to detect it. Stock settings worked perfectly.

Vtt borders
Just like the r2e , the dfi also shows that crossing over a certain voltage on vtt, U might sometimes get weird initial results

Example
Stressing 1.43 set result in bsod
Up the voltage to 1.45v the computer does a shutdown reboot with no display. Shuting down manually and rebooting it.
problem solved.
But in occasions doing the exact two things above results in bios corruption.
so setting the 1.45v from default settings u dont get the issues above

Your Case
DId u have any problem with ram stress test and stock?? Did the bios detect full 6gb at stock voltages.
If yes than high chance is not the board, ram. Its either two things.
1.Ure voltages were incorrect ( take note not saying the voltages were insufficient)
2.IMC issues.


Elimination of voltages
For i7 you need to eliminate voltages on every scenario. Vcore, Vdimm ,Vtt, IOh.
They have also tendency for certain ratios. U have to identify them.

Examples of Faulty test
Also for my case using DMM i found that 1.65v is undervolted to 1.62v
Memtest HCI and memtest86+ , testing both of them for hours i had no issue running my rams at bclk 201 1004mhz CL7 1N.
However this failed to run prime95 blend 25.9 64bit. I was preplexed.
Issue was resolved by increasing the vdimm voltage set at 1.665v, DMM read was 1.639v and setting bclk 200 and rams at 2N.
After doing this i had very consistent results on any test i threw at it.

Not to Do
Basically so far any plug and play or just increasing voltages to solve test failures wont cut it for X58 when it comes to high uncore and faster dram speeds. Stressing at wrong voltage ratios itself can result in weird behaviours like what i had, missing rams etc. This is why whenever i see issues like this , i usually reset to default and reflash the bios. I find memtesthci is the best test for vtt and ioh ratio.
prime95 blend 64bit 25.9 for dram timings and voltages. linx for vcore.
