Im not chaning it... i want it to do automatically like on default settings... so that the BIOS lowers the VCore along with the multiplier when the CPU is idle.
It works on default settings... and i want it to do the same with an overclocked CPU.

Are you using offset voltage, or fixed voltage? If there is a choice, use offset over fixed, as fixed will do what you described, but offset will change based on the frequency. For example, I run my 2500k at LLC4, and +.185 volts offset, so I can have my 5.1ghz cake, and have nice low volts at idle too.

I'm baffled..

I just followed the guide step by step, and I'm currently running 5Ghz overclock without any problem?
Prime has been running for almost 1 hour now, everything passed. Temperatures are at 75-85 Celcius, so quite ok.

Is this possible?

If this keeps working, shouldn't I clock down a bit to for example 4.7 to save my CPU? I don't want to destroy it. Will clocking it down that 0.3 Ghz keep it alive longer?

That is something you should decide for yourself, based on your desired life expectancy of the chip, and your need for speed. Voltage and temperatures destroy chips. When that happens is based on how much and how hot for how long. I run 5.0 around 1.35 under 70C, I am not worried about degradation with those numbers.

I'm very new to this, so I don't really know what I'm doing.

I set all the settings according to the tutorial and just did "Set the Offset to +0.005v. Set the Turbo Voltage to +0.004v"
So I really don't know what voltage I'm running at now.

Just following the tutorial gave me a 5Ghz stable (at least for 2 hours of Prime95) with temperatures maxing at 81-92 Celcius (depending on the core) and the voltage in CPU-Z was about 1.360 (maximum value in HWMonitor)
Average temperatures where about 75-80 Celcius.

This is at full load, so I imagine this isn't too bad because under normal workload you won't even get near these?

But lets say I want to spare my CPU a bit and go with a 4.8 overclock, which I asume will be stable for sure.

Can I make the voltage smaller to decrease the temperature? How do I do this?

Is it even recommended to stay at 5Ghz, given the temperature wont go above 50 Celcius (just making this up) under normal use? Or is temperature not the only thing hurting the CPU?

As far as I now the only thing I now did was up the multiplier and all the rest is on stock settings right?


Thanks in advance

Set the multiplier to 48and leave offset/Turbo at +0.005/+0.004. What is your idle and full load vcore in CPU-z?

What CPU do you have?

Hi all,

First time i have tried overclocking (using BIOS firmware - 2.90 with rig in signature), so have been following the guide on Page 1. All the settings (except for the ones below) in my BIOS are set to the same as the instructions and I am currently aiming for a multiplier of 45:

Offset: +0.005v
CPU PLL: 1.709v
CPU LLC: Level 3
Turbo Voltage: +0.078v
DRAM Frequency: 1600
Command Rate: 2N
C1E: Enabled
C2 &C3: Disabled

I ran the Prime 95 test as per the instructions for just over 1 hour (VCore: 1.238 according to CPUID), no crashes or errors on Prime 95, but got 1 WHEA error after about 20mins or so and got a temperature of 91 Degrees Celsius - do you think this would cause any issues or CPU degradation (I've read on other sites that people recommend keeping the CPU Below 80)?

I am really only wanting to use the rig for gaming, so not even too sure if I need to push it to 45, but wanted to give overclocking a go! Also i read somewhere that with SLI 670s then a stock I5-3570k may have some throttling issues - anyone know if this is true?

Cheers

Mark

The 3570k is a fine chip for gaming. Very few games are threaded properly to take advantage of more cores. SLI 670s + 3570k makes for a good pairing.

I run a 3570k with 3 x 290x and it handles them all very well. I don't think you will have an issue with two 670.

Thanks for this guys - so the 1 WHEA error after 1 hour run on Prime 95 should not really give any issues? According to the guide, increasing the Turbo may stabilise the overclock further (maybe getting rid of the WHEA error), but the temps go up to around 95 Degrees Celsius in an hours run, when i tested with those settings, which is right at the limit according to the guide - do you think there are any other settings i could change to decrease the temps?
