Mean Aerodynamic Chord

I can't get passed 4.2GHz!

Recommended Posts

LOL well at least it is not your memory. :) Besides your voltage is way off. Try a CPU voltage of 1.4vcc. Run prime for awhile and if it runs for say 15 minutes lower it to 1.375vcc. Then repeat until it fails. IB seems to need less voltage IMO but I still need 1.44 to run stable at 4.9. I can easilyt run 4.5 at 1.3 but that is on an IB.

Sorry, but I'm not going up to 1.4. I want to stay below the 1.390 range. I'll try 1.375.

Alright, 1.375 seemed to work with 4.5GHz for 15 minutes on Prime. It ran a complete self-test and it passed with no BSODs. However, Real Temp reported temperatures like this:

 

 

 

This was taken after the test was stopped. Take a look at the maximum temperatures. Is that too high? I can increase my fan speed too, btw. Also, lots of people recommend running a test overnight to truly test the clock, should I do that?

Right now I'm back down to my original 4.2GHz with 1.315v.

 

How long did you run at your original?

78 is fairly high.... I'm telling you - you might have a dumb cpu like mine.

 

Suggestion: Be careful, but while in BIOS set vcore to AUTO, leaving XMP enabled. And set multiplier to 45x. Save settings but remain in BIOS and check the temp and voltage right away. It would probably be around 1.35- 1.36v. If it's anything above 1.4 go back to what you had previously.

See if you can run at 1.35 which is an ultria safe voltage and should bring your temps down. An hour should be good enough IMO.

Do you mean the Prime test? Forever. It was very stable.

I'd rather not risk it... Too expensive technology!! lol

Let's see.

 

EDIT: I BSOD'ed with 1.35 at 1 minute of testing.

Be happy at 3.71v. Be careful w/ too much overvolting to get that last [virtually irrelevant from a performance standpoint] bit of clock speed. I killed an expensive E processor doing that so I speak from sad experience.

Buy the very cheap Intel overclocking insurance, less stress.

 

Surprises me how many of you guys have to disable power saving features, I use them all, and have no issues running at 4.5.

 

4.6 is okay too. 4.7 on the other hand, requires a whopping 4.5 volts and temps go through the roof. Not dellided.

Well this is what I had to do for mine. Its not going to blow up

On you at idle. Even though auto vcore sets 1.356v under load my system would BSOD if I set vcore to 1.356v - doesn't make any sense right?

 

Regardless I've been running For two years now with no issues on auto

I ran into a problem with my H100 water cooler and had to have it RMA'd. Until I got the new one I had to drop my OC to 4.2 and I was amazed at how well everything ran. 4.2 is a nice OC for FSX with that CPU. If you can go higher that's great, but 4.2 should make you happy.

 

Edit: As I was scrolling down the post I saw the screenshot of the BSOD and it made my heart jump lol. I feel like Pavlov's dog sometimes...

You might want to sign up for the Intel Tuning plan. If you CPU is less that 12 months old you can get a warranty that covers overclocking. It will give you a one time replacement should you fry your chip.

With regard to your BSOD it is most likely the vcore being too low.

 

I am currently running a 2500K at 4.7 w/ offset that sits around 1.38. I initially started stable at 1.42 and worked down. Now I am IBT and Prime stable under 70 degrees.

 

Remember the 2500k has a max voltage of 1.52 but most people live with the no more than 1.4v and 70 degrees in Prime rule.

 

 

Asus did a review of 100 D2 chips and found the following:

 

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)

 

So you might just have a chip that can't get a high OC or a power hungry chip.

 

Are you using manual volts or offset?

Alright, I went back to 4.2GHz with 1.315v. It seems like this is really stable, no crashes so far. Would water-cooling help with my problem, or is it not really temperature related? I mean, I don't think so.

I'd still try auto vcore... just in bios to see what it sets the volts and temp too. I don't think water cooling will help.... there is definitely some other problem (I agree probably voltage related).

Yep, said the same thing myself a few posts before yours. Cost me a mere £25. Takes all the stress out of overclocking.
