Core i7 Vdimm/VTT Graveyard :D

[saaya]

actually pushing ioh volts does help with mem clocks for linx/prime and super pi 32m stability http://i4memory.com/f80/i7-920-d0-df...ability-16617/ for some

yeah, but only at high bclocks right?
when the prob is that qpi/bclocks arent fully stable, at least in my experience... and its a bit weird, some people seem to need high ioh, some say it doesnt help and some say it makes things worse if ioh is too high... i suspect it has to do with what bclock your running and possibly on the cpu and chipset.

btw, that zoom feature on large images is very nice...

2.10v vdimm / 1.82v vtt = ok for 2 days of non stop 3D Mark. (air)

thats high!
did you notice different ocing after this?
do you need more volts for the same clocks or can you reach only slightly lower clocks when maxing everything out?

I'll PM you shortly as soon as I've fetched all BIOS settings. My modules are 1 GB modules. The TW and 2G in Corsair's article codes refers to a twin kit of a total of 2 GB. So I wouldn't like to run on only 3 GB.

According to Everest 5.01, I am getting a read throughput of roughly 14 GB opn 7-7-7-20/1200 but up to 17 or 18 at 9-9-9-24/1600. The question is indeed if that would reflect in a higher system performance....

more bw helps in some apps, lower latency helps in others... the difference is really small in my experience, but games tend to prefer latency since bw on i7 is pretty massive to begin with.

1600 9-9-9-24 is the XMP profile's settings stored in the modules, but they run fine at 8-8-8-20/1600 too, except for certainly still having those reboot issues.

hmmm could be that the memory pwm gets too hot or cant cope with the load... but that doesnt make much sense since your on a p6t and they have 2 or 3 memory pwm phases right? do they get hot? ask asus tech support about it... maybe your on an early pcb rev and theres some prob... who knows...

i remember that the renessance had similar probs early in development, it was some prob with the memory pwm... but it only happened with certain psus for some reason... so kinda a psu mem pwm compatibility... try another psu, maybe its the same thing.

What I mean by moving one memory module is that the manual states that for a four module configuration one should use slots A1-A2-B2-C2. '2' are the orange slots, and A1 would be the black one closest to the CPU socket.

When it comes to bus termination, and the RAM modules' on-die termination, wouldn't it make more sense to have the fourth module in the last of the black slots? To terminate the signals at the end of the copper traces.

each channel is terminated independantly, so i dont think it matters... channel a has the shortest traces so thats why intel recommends using 2 dimms there if you use 4 afaik.
