Can you order a chip and ask not to receive one of the lower clocking ones?

Not really - Best guess is if you are able to go to a computer shop and ask if you can see the different cpu boxes and select one that's made in a country has been reported to be most overclockable. (costa rica, malaysia and what other places there is that they make intel chips)

 

But no, pc stores have no idea which chips overclock best, as it varies per chip so you'd have to test everyone of them 1-by-1. Closest you can get is attempt to buy a haswell that's made somewhere that's known to usually overclock well.

I'm currently stuck at 4.6Ghz which is default optimized setting for my Asus board. Have a look at my system specs and many thanks for hints...huhuh James.

 

I'll reread this thread but never have overclocked before.

So thanks.

Your system is almost identical to the one I'm building now, for example the same mobo. What cooler you use ?

The FIVR will take you to 4.6 - 4.7GHz then quit. The rest of the way is with manual core voltage and VCCIN.

 

James, what exactly is VCCIN and FIVR as I cannot find it in my bios?

 

Jfir, a Corsair H90. By far enough...and quiet.

FIVR = Fully Integrated Voltage Regulator

Vccin = Input voltage

4.7GHz @1.3V. Cooling with Thermalright Silver Arrow. FSX plays beautifully.

4770K - running nice at 4.4K @ 1.2V with 16GB 1866 - CL-9 And haven't even pushed it yet and see no need to de-lid (probaly good for 4.6-.4.8)

Luck of the draw as My 4670K would not go any better than 4.5 at xtreme voltages and thats runiing delided with no IHS!

 

Funny, the Ivey chips from Costa Rica awlays seemed to be the best but Maybe not for Haswell.

 

My slow I5 - Costa Rica

The I7 -  Malaysia

 

Anyone else?

 

Results are not conclusive. I've read that the Asian batches are the ones to avoid, and the South American ones run cooler. However there's a huge variation between chips from the same plants too.

 

There's also the issue of people using different tests to measure temperatures. For example, Linpack 11 with AVX2 instructions will run about 15-20C hotter than Prime95. Prime95 in turn is about 10-15C hotter than AIDA64 with CPU+FPU checked. So two different users could report 65C and 95C respectively under what they call "full load", while in fact there temps are exactly the same.

4.7GHz @1.3V. Cooling with Thermalright Silver Arrow. FSX plays beautifully.

 

In what computer case ?
