Looks great, Nice oc.
Congrats mate you are on the good way, not always vid 1,25 means bad...Quote:

booted from bios at 530 with 1,408 just was my first shot with 535 i gave a bump on vcore as im trying 540x8,5 let's see how it goes :rolleyes:

Damn, good job man.:up:
Thanks mate :up: too damn hot got 25,2 in my room today, when temps go low i will shoot againQuote:

What is the maximum voltage for these CPU's please?

mean was 1.328v at 3.91ghz at over 4 i gotta go pass the factory volts of 1.362v
to even get 4.0..i gotta work that some more when i build my system back
Maximum voltage as recommended by Intel! I thought it was 1.45vQuote:

1.45 is the rated max according to intels data sheet. Im not sure where people are getting 1.3625 from, I havent seen anything from intel saying thats the max. The only thing I can think of is people see the max VID rating being 1.3625 and think that is Vcore. :shrug:Quote:

so your saying the Total Max volts on the 45nm chips are 1.45v can you link me to a Intel data sheet to prove that by intel volt specs for me to see? i haveQuote:

Thanks
Try this, the site was acting up a while ago. Heres a ss if it doesnt load.

Unless im totally misinterpreting this, table 2-2 shows max and 2-3 shows 0.85v-1.3625v to be the min and max VID range.

There is a difference between 'max' and 'absolute max' vcore.
Max = 1.3625v
Absolute max = 1.45v
If you read the portion of the data sheet I have quoted below, it states that the max voltage is the functional limit of the processor. The absolute maximum voltage lies outside the functional limits of the processor, and long term reliability will be affected to some degree with the severity determined by the length of exposure to these voltages. If you go beyond the absolute max voltage, the processor may not function anymore, or will have it's reliability severely degraded.
We know the CPU's will still function after excursions above 1.45v, however we have no idea how badly they have been damaged. I have benched my E8600 at 1.56v on air for hours with no obvious ill effects.
It should be clear that 'safe' vcore = no more than 1.3625v
Quote:
2.6.1 Absolute Maximum and Minimum Ratings
Table 3 specifies absolute maximum and minimum ratings only and lie outside the
functional limits of the processor. Within functional operation limits, functionality and
long-term reliability can be expected.
At conditions outside functional operation condition limits, but within absolute
maximum and minimum ratings, neither functionality nor long-term reliability can be
expected. If a device is returned to conditions within functional operation limits after
having been subjected to conditions outside these limits, but within the absolute
maximum and minimum ratings, the device may be functional, but with its lifetime
degraded depending on exposure to conditions exceeding the functional operation
condition limits.
At conditions exceeding absolute maximum and minimum ratings, neither functionality
nor long-term reliability can be expected. Moreover, if a device is subjected to these
conditions for any length of time then, when returned to conditions within the
functional operating condition limits, it will either not function, or its reliability will be
severely degraded.
Thanks for clearing that up for me and others anything outside of 1.3625v is putting damage on the cpu if you hold it there for a certain length of time and even if it still passes the intelburntest and orthos stress tests it's even putting more hurt to it cause of the stress of heat build up dueing the tests bein done:shocked:Quote:

VID is the voltage identification register, which tells the motherboard what the voltage it is supposed to set for that chip. Every individual chip has a different VID. So in a way, Vid "IS" Vcore in a way. One Q9650 might have a 1.15 vid while another has a 1.3 vid. This is just what the motherboard should give the cpu at auto vcore, if the bios works correctly.Quote:

But you're pretty much able to raise voltage up to the highest vid range for the processor line without risking any damage.
Yes, I know what VID is. :up:
Give your chips whatever you feel comfortable with, but I was just clearing that up for those who want to remain totally safe. Despite this being XS, there are some people who saved for their CPU's and don't feel comfortable running them out of spec.
Max safe vcore is 1.3625v no ifs or buts. That's what intel state. The fact max VID is also 1.3625v does not change anything, or invalidate what they describe clearly in the data sheet.
How long a chip will be 'ok' for at voltages above 1.3625v is another topic completely, and depends on many factors. That's not what was asked though.
Care to validate your points above? Especially where I highlighted.Quote:

Was it your own guesstimation, or is there any other statement or table from Intel missing from this quote? And do you have a link to the datasheet which covers that missing validation?
Here:
Intel states the absolute maximum and minimum ratings as -0.3 - 1.45v. What voltage range lies within this range? The max and min range (0.85v - 1.3625v).Quote:
At conditions outside functional operation condition limits, but within absolute
maximum and minimum ratings
Therefore functional limits = 0.85v - 1.3625v
Absolute max and min = -0.3v - 1.45v
EDIT - The tables posted above by Hoss331 show both max and min and absolute ratings. The data sheet is freely available on intels site.
