ASUS A7N8X-E with mods for Vcore, Vdd, Vdimm, Vtt
Vcore:2,07V; Vdd:1,95V; Vdimm=3,57V; VTT=1,649V;
TerraRaptor says:
Just curious what vtt is? Is it dram vtt?
Tzk says:
@TerraRaptor
Yes it is. Atlan1980 (member of hardwareluxx.de) reworked the whole Vdimm feedback loop and developed a Vtt mod for the Asus board. He introduced smaller resistors for the FB loop, swapped the mosfets and coils in the Vdimm regulator and removed a cap in the feedback loop which basically eliminated the Vdimm drop under load. We're now at <50mV drop under load at high vcore. I haven't tried it myself, but it looks like we can push much further now, even with TCCDs. @digitalbath managed to pass a 260Mhz 32M run with 2x512mb TCCDs

I had to lower the dram vtt Voltage to get my AT-6 sticks stable for 250MHz and above. I also recapped my board with solid caps.
TerraRaptor says:
Yep, digitalbath sent me that link some time ago, thanks guys. The reason I questioned it was vtt level mismatch (50% default) used here. Will test that mod too soon (though smd soldering was always a challenge).
Tzk says:
My guess is that we‘re getting some vdimm drop on the sticks which results in a lower(ed) vtt voltage requirement.
Ive still to try the newer mods, i havent got any decent dso or analog scope to measure ripple and thus i can‘t test those new mods myself yet...
