Name that white sheet! - Page 2

post #11 of 18
Top one is right. 1.65V vDimm and 1.55V vCore voltages are a dead giveaway.

I have no idea what the second sheet is for.

And what about the 1.21v VTT?


Mind you, again, I pulled the second one directly off Intel's datasheet for the i5 750.

Exactly. I'm as confused as anyone.

The specs of the top one seem to fit the 750, all except the VTT.


I see people throwing around all kinds of "max" voltages for all kind of different chips, so I decide to look into it for myself and this is what I find. I'd really like to find someone that can explain which is correct and why, and then explain what the other sheet is refering to.

here a post by uncleweb when the i5-750 first came out.you can see it say 1.55v
and 1.21v so i think the i5-750 data sheet was revised later on.

** OFFICIAL ** Core i5 Overclocking Results/Tips Thread post 149

so i think thats whats going on here.on page ten they discuss it more some though 1.35v
and others 1.21v.it was a confusing time
and now the sheet is more like the new i3-i5 32nm ones
so what do i win for solving this

i'll wait for my prize

I swear I remember reading that in my MB manual also. I looked back through it and I can't find it. But I distinctly remember reading somewhere that VTT was limited to 1.20v in the BIOS on that board because Intel spec said 1.21v is the max.
