Quick question guys, i have the 2600k and have it running at 5ghz but having to use 1.49v to keep it stable. My question is, when not on high load the core speed drops. Is there a way to have the core voltage drop when also not on high load? because i dont want to be running 1.49 all the time


edit, i didnt use offset. messing with that now. just realised what id been doing wrong lol

1.49V :eek: intel says no higher than 1.38V or you will seriously reduce the life span of the CPU.

do they? Were?

Wish people would stop telling people this. Every time i say proof i get no reply.
1.49 is high. I though i had a bad chip.

You need to mess with that off set thing. Ive not worked it out. Not had time. But when you do post back.

Take a look at this thread a guy explains it in there. Also you will get an idea for what volts you should need. I dont think you will need that with tweaking.

There is k link inside that thread of a guy from asus going through settings. Would help more but im on my phone

. Just set the dynamic voltage to 1,25 then you wil have under load 1,4. If you need more voltage but want to keep the idle voltage low, then increase the CPU Turbo voltage offset in small steps to achieve stability.

the reason you dont get any replies is becase the info couldnt be easier to find:

i7 2600k product page
***OVERCLOCKING GUIDELINES***

- Do not exceed 1.35-1.38v core voltage, doing so could limit lifespan of the CPU
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!

Hi there


Right guys myself and our technical guys have spent the entire weekend and this morning in discussions with Intel regarding the alarming amount of reports of Sandybridge CPU's dying and have been conducting our own testing as have Intel to find out what is a definite no no.


Sandybridge maximum safe voltages

Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking.
Memory Voltage - Intel recommend 1.50v plus/minus 5% which means upto 1.58v is the safe recommended limit. In our testing we have found 1.65v has caused no issues.
BCLK Base Clock - This is strictly a NO, anyone using base clock overclocking could/will cause damange to CPU/Mainboard. (Set manually to 100)
PLL Voltage - Do not exceed 1.9v!!



Processor - Basically we recommend customers not to exceed 1.35v to play it safe, all our bundles are set at 1.3250v or lower, any competitors offering bundles above 4.6GHz you should be enquiring as to what voltage they are using as we believe anything over 1.38v will limit CPU lifespan and anything over 1.42v will likely kill the CPU or severely limit its lifespan.

Memory - Intel recommend 1.50v plus/minus 5% which means 1.60v is the ideal safe maximum, but we have found in our testing all 1.65v memory is fine. We have also found most new 1.65v like Corsair XMS3 will run at its rated timings with just 1.50-1.55v which is well within Intel specifications. So people upgrading to Sandybridge you can still use your old DDR3, but we do recommend you run it at 1.60v or less. We are shipping most of our bundles which feature Corsair XMS at 1.50v-1.55v at rated timings. We've also discussed with Asus and MSI regarding voltages for memory and they also confirm in their testing 1.65v caused no issues with reliability.

Base Clock - To put it simple if you value the life of your components, do not overclock using base clock!

PLL Voltage - Again do not exceed 1.9v!


These are just guidelines we recommend you follow, if you want to push more voltage through your CPU's then just be aware they could die on you. Your warranty is un-affected and we will honor any CPU's that die, we just won't ask questions as to how you killed them. ;)

Not all CPU's are as fragile as others, we have experimented upto 1.50v Vcore and 1.70v memory and had zero issues with reliability, so it seems some of fine when pushing hard. :)

also, bear in mind that when they said about the 1.5V not causing problems there was no way they could have done lifespan tests at that voltage because they simply hadnt been out long enough to do so
 
Yeah I know that voltage was ridiculous, I've started fresh with the help of one of the ocuk members. We spent some time in it last night and are continuing tonight: so far on 4.5 ghz using 1.32v. He says I have a really good chip which is pleasing to hear. Once we get to where we can and its stable, ill post pics and results.
 
lol i will be off/on tonight as early start tomorrow :(
i cant see why you should have issues with what you have got, especially as you seem to get no vdoop at all :) i think you may even be able to drop back to 1.30v or 1.31v, but 1.32v is a good start as it should be more than enough so any little instability issues wont pop up.
 
When I shut down last night it did freeze on Windows shutting down page. So if anything maybe I need 1.33. Anyway ill catch you later or tomorrow mate, thanks. Seems fine mate, upped it to 1.33 and primed for an hour for quick test, no problems. But it actually said on core temp it was only using 1.32 but cpuz said 1.334, so ready for next step now. Also it passed IPDT 5 times.
