Core i7/X58 Overclocking Thread

[Metroid]

--------------------]

Download the latest Realtemp program and you are going to be very surprised.

Right on guys I finished my 24/7 crunch system:

Air Cooling True Copper lapped:

First lets see 4.0Ghz 8 threads ran for almost 20 minutes maximum 88c.



4Ghz 20 Minutes 8 threads =

Maximum: 88c
Average Maximum: 85c




3.7Ghz 8 threads 7 Hours Prime 95 =

Maximum: 73c
Average Maximum: 72
Load minimum and maximum average: 2 hours = 540 / 8 = 67.5

3.8Ghz should be a little higher.

4Ghz to 4.2Ghz means:

200Mhz x 8 cores = 1600Mhz which is converted into heat into heat.

So it looks like is a general problem for aircooling users, this chip is too hot. The only way to get 4.2 Ghz to work with 8 threads is with a good watercooling.

By the way 1 fan 1300RPM 54CFM for me is better than 2 fans as the latter was explained.

This was an interesting week,

Thank you all who participated and contributed to this thread. This is a very good thread explaining many things about this amazing processor.

Well I will keep at 3.717Mhz 1.168V 24/7 8 threads mainly because my goal was to keep 4 to 6 logical processors for the World Community Grid xtremesystems team.

I will only use 4.2Ghz if I need to bench for any reason or if a game does not run at 60 frames per second and the same needs a CPU boost or to play the best Playstation 2 emulator PCSX2 at amazing frame rates which is a CPU eater.

I spent all my money building this system which I do not regret at all however if I only knew the best aircooling solution would not stand for 4.2Ghz then I would have built a water cooling solution. Well there are things we can not go back in the past. It was done and was for good.

I will change to water cooling in the next few months and keep at 4.2 Ghz 8 threads. I still think it is possible to keep such speed with a good water cooling solution. There are good radiators out there in the market.

Real Temp 2.70 is the latest version i see on google. do you have a link to version 2.90?

Edit i found it. Not much differance in temp readings more even if anything.

With "Turbo"on!

Prime 95 - 4011Mhz - 1.18v! No problem!

Let it priming. Have you tried 1.10V 8 Threads 3.7Ghz

My case is, it boots at 4.0Ghz 1.18V 21x191 = 4.009 Mhz then it freezes after 30 minutes priming.

You have a freak CPU

It boots with 1.10V no problems run some programs.

The maximum I could get stable with 3.7Ghz 8 threads at 1.14V. You still have a difference of 3 to 5 volts which has a better yield than my chip

lol why search google, when the official real temp thread is here?

I would say the same, if they could only see XS Bench they would understand that the official thread is a sticky for the same reason.

By the way hornet what do you think of my WCG system?

looks very good, 3.7ghz with 8 threads and only 70°C under prime is awesome.

Maybe you could try 3.8ghz, since the WCG WUs usually produce much less heat then prime.

btw. why do you run the NB only with the 16x multi?

Thanks,

Well to tell you the truth. I found out if you feed it with 13 to 16x then my system will boot with low voltage and it is more stable. I know it is strange. The memory has to be 6x and Uncore 13 to 16x. If the memory is x8 then the Uncore should be 17 to 20x.

I hope this info will help you guys out on the quest of getting a very good lower voltage with higher clocks.

LOL nicely updated. where is 2.90

maybe scroll down some posts.

aww, unclewebb already posted it.

Nice 24-7 for me looks like 3.7- 3.8 is perfect for air 24-7 without stock heat sink. I need better cooling load temps are to high for 24-7 @4g , my load temps were way to high so i did a nice prime at moderate 3.3 27 hrs I dont like seeing it that high of a load temp. Love these new chips I especially love the 4 cores 8 threads. Im waiting for the next round of heat sinks
