Is my CPU Special?

[beanoslim]

2600k
Sabertooth P67
8gb Crucial DDR31866
Corsair H100

Overclocking so far...

4.8ghz
10 Passes Intel Burn on MAX
1 hr OCCT
Short run Prime 95
5 days F@H 24/7

1.33v
LLC - High
Duty Control - Extreme
Phase Control - Extreme

Moved onto 4.9ghz, same settings as above execpt cpu voltage up to 1.39v

So far 24hrs F@H completed so testing not complete.

Not looking for gold stars or bragging rights just wondered how this compares with other chips OC results, heat and voltage.

The heat has definately gone up since going to 4.9ghz, especially around the chipset, I have an assist fan but not keen on running 70C 24/7.

Any thoughts??

That is a good overclock compared to many people have an good air cooler and reaching about 4.5GHz.

The Sabertooth is a superb overclocking board.

1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)

That was "at release", I'm sure numbers have improved since then.

What do you think about the chipset temps for 24/7?

Hi

You do realise that overclocking SHORTENS the CPUs life ? .....and the higher you overclock , the shorter it gets ....

All the best Brett

 

[beanoslim]

Of course.

Every CPU is special...errr...or is that every child is special. Too much time on online forums.

 

[FlintIronStagg]

Kind of overkill anything over 4.5.... Thats if you need the processing power

 

[beanoslim]

Well atm I'm just seeing what it will do.

I usually ramp it up to the max to see whats possible and then settle for best voltage/heat/speed as final OC.

Managed to get my chipset temps down to low 60's even with the 4.9 OC by switching my rear exhaust fan to an intake.

I suppose 5ghz is next.

Testing..

Needed 1.41v to pass Intel Burn

Thats a respectable OC you got there

in 2 more days my Noctua NH-D14 arrives and I can start playing with my "new" Xeon X5650

Though I will be happy with something more like 4.5GHz on that chip I think

if you only need 1.41v to keep 5 ghz i see no reason to downclock if you can keep the temps low.

 

[beanoslim]

^ :lol:

Since switching the rear fan to intake the chipset temps have been around 60C, I'm happy with that.

CPU temps haven't been much of an issue with the H100 but as the volts are going up the fans are getting louder!

Might have to considor some replacement fans that are a bit quieter if I'm going to keep it ramped up.

@4.8 with 1.32v it was nice and quiet, I may well just drop it back down to that for long term use.

The bonus is with this setup is being able to run the OC with Speedstep using the offset voltage, therefore prolonging the life of my cpu.

What do you think about the chipset temps for 24/7?

Not much point in worrying about the chipset temperature since the IO Hub runs at stock clock regardless of how high the CPU cores and memory controller are overclocked so it should run at the exact same temperature as it did before.

VRM and CPU temperatures would be a different story.

My 2500K can hit 4.5ghz with 1.236V
http://valid.canardpc.com/show_oc.php?id=2414233

Takes 1.4V to hit 4.8ghz with my 2600K, 1.44V to hit 5ghz
http://valid.canardpc.com/show_oc.php?id=2435301

1.48V for 5.1ghz

[beanoslim]

Is that booting into windows or long term stability?

 

[beanoslim]

So this is where most of my high temps were coming from (red circles)

Listed as VCORE-1 and VCORE2 in the Asus Thermal Radar

This pic shows idle temps, they were hitting over 70C but got them down to 60C now with new fan arrangement.

 

[Pailin]

Handy app, I like it

still, on that board looks tricky to do more than you already have done, but then 60c is a pretty acceptable operating temp

 

[beanoslim]

Yeah I like it also.

Dropped back down to 4.8ghz with lower voltage.

CPU and Vcore temps down to 50C under full load.

Just need a couple of new fans and I think I'll be happy.
