Intel Posted Absolute Min/Max Voltages for Sandy Bridge-E

post #1 of 11
Thread Starter 
I just saw hazarada mention in another thread that Intel posted the absolute min/max voltages for Sandy Bridge-E (http://www.intel.com/content/www/us/en/processors/core/core-i7-lga-2011-datasheet-vol-1.html).

Intel hasn't posted the absolute min/max for the regular Sandy Bridge, but they are probably the same or similar, since they're both based on the same architecture. We don't know for sure though, so keep that in mind.

394

Vcc = vcore
Vccd = ram voltage
Vtta/d = vtt, vccio, or imc (integrated memory controller) voltage

SB-E is not necessarily the same as SB. Yes the architectures and manufacturing processes are extremely similar, but there are some important differences. Still, it's interesting how they compare and how SB's absolute min/max table is still omitted.

Also, you should not be using these absolute maximums as a guide for what is safe to set, as they are meant to be the limit for very short term transients, not continual use.

the big text only states what happens if you ignore the fine print. Clever wording to deter people seeking for a straight answer i guess tongue.gif i get a feeling intel doesn't want anybody to OC anything

Yeah, I wouldn't want to run vccio or vccsa anywhere near 1.4v, but it was interesting to see that they also listed the absolute max vcore at 1.4v, which most people would consider as safe.

I don't understand this...everyone runs with VCore well above 1.4.

Doesn't mean Intel will stand behind the processor if it dies. Granted they probably will because Intel is awesome like that. Just means they don't have to. wink.gif

Right, but is this lawyer specs or actual specs is more what I'm wondering.

I was quite under the impression that VCore of 1.5V even is pretty much fine long as your temps are under control etc.

this is lawyer specs, meaning 1.4 is the last number where everything was hunkydory with every chip sent off to a store shelf. after that i guess some specimen started showing various degrees of degradation, how many and how severe intel only knows.

I know there are plenty of people running their SB chips @ 1.5v for a long time and i cant recall any of them reporting the chips dieing but this is still just anecdotal statistics. Personally i think if intel stated a number and is willing to put its money on it then im more inclined to trust that rather then what the latest word around the web is.

Was there no pdf file released for 1st gen SB then i take it?

there was but no max was specified. Only thing in there that listed core voltages was the VID table of what each byte means in voltages, naturally people jumped to the highest possible number (where they ran out of byte) and assumed 1.52 must be safe laughingsmiley.gif
