Did we ever come a conclusion on safe SB voltages? - Page 7

vDrop and vDroop can kiss my ass... Why cant the voltage just be exactly as you set it?

The real world has a nasty habit of being real.

Agreed. I'm more curious why it seems so much lower on AMD chips compared to intel.

AMD has always had a much more power-friendly architecture. As such, it doesn't end up drawing as much current, which end up meaning a smaller vDroop/Drop. (This is highly simplified; if you want a more technical explanation, be ready to read a lot)

So the difference between these 4 numbers (the two VIDs and the two voltages) is 0.0359/0.0309 and 0.0439/0.0389. My Offset ended up needing to be +0.040V to achieve the voltage I want, but someone else with an identical system may end up needing +0.035V or +0.045V.

So yeah, that's basically it.

If you lower the LLC to the 3rd highest setting, then the Offset will need to be adjusted a bit to compensate. If the LLC is raised to the highest setting possible, then of course the Offset will need to be adjusted the other way.
Hmm, so that's what offset is all about.

I feel Gigabyte is simpler - simply set your VID in bios, and select a LLC (level 1 to 10) to achieve the desired delta-V between idle and load.

Example, my voltage is set at 1.330 in bios, with LLC level 6. At idle I get 1.340 and under load I get 1.392v. So I guess by Asus standard my offset is 0.052v?

When I was seeing how much my system would post with out H/T enabled, I used Turbo Evo and auto overclocked. What I could not believe was it stuck me on a auto voltage, 103 BLK, with 50 multipler, thats 5.15GHz overclock. The problem was the voltage was 1.48v and with auto would jump to 1.53v at times. Wow I don't think my air cooled mobo can with stand jumps up to 1.53v...
-I'm sure with no H/T enabled spiking your temps, on an air cooler you could 1.51v max.. Right now with 1.47v I have yet to see a temp over 63c even after a full night of play Crysis 2

Don't be askeered! this is OverclockDotNet!
Intel specs:1.52 vCore
72c T(whatever) max
umm..i can say for sure 1.76v=too much
but..temps allowing..i'm not afraid to push the envelope a little ..i don't see why ..say..a 5.x ghz OC with 1.53v 24/7 isn't feasible

Guess it all depends on how long you want the CPU to last.

Intel design them so that you can buy a 286 upon release, run Prime from the mid 80's till now, day in day out, and still without hiccup or degradation. Since no one want their 2600k to last till 2041, I'm sure we can increase voltage by quite a bit, especially if you're upgrading when IB hits.

You are confusing vcore with VID. 2 different things. VID is used (mostly?) for offset. Gigabyte doesn't allow LLC with offset in their bios' (at least in mine and others, there may be exceptions?). OT I know, sorry.

But but but....

I wanted to pass down my 2600k from generation to generation, like a family heirloom!
