Here's ten bucks. The channel wide August rebate form from the Newegg page works with the Microcenter board. Sent them my register receipt + UPC & got $10 on their July rebate.

I was just checking the new haswell vs Sandy efficiency just for fun.
I happend to have a old Sandy 2500K, been running that chip 4,7-4,8ghz for ever it seems, so i knida know that one well.
Note that the memory is not at the same speed,I will test at same memory speed tomorrow for a better and moore accurate comparison between those two (G3258 and 2500K)
Testing is only singlecore apps,mostly superpi and pifast, anything else is a no-go cause the lack of AES and AVX instructions on the Pentium.(and because it only has two cores of course..lol)

So heres what i discovered about pi today, same speed 4700mhz the Sandy crushed the newer Haswell in superpi1M. (memoryspeed and timings,I know) its Haswell@2133Mhz(2T) vs Sandy@1866Mhz(1T) (slighter better timings too)

The time for Haswell is on page 84-85 I guess, i posted a pic on superpi1M, timefor Haswell was 8.018s and for Sandy and its 7.941s.
I havent done under 8sec on the Pentium yet,need tweak subtimings in bios. But the Sandys timings is NOT optimised either,just fast settings i know will work.

Stupid me,closed the pi-window after a 32Mrun so no pics,but the story is the same there,pics tomorrow after testing.

Heres Pic of my 2500K@4700Mhz@spi1M



Cooling for Sandy


Anybody else done any comparison? Please share..thanks wink.gif

Awesome Thanks! I love rebates smile.gif.

Nice comparison I got 2500k nice CPU but I wanted to move to the small form factor of the 1150 with this awesome monster g3258 smile.gif comparisons between this 2 are welcome !!

Could only get this to 3.9 GHz

Tried even putting the voltage up to 1.3V and still no good

I have a similar experience. My board is Gigabyte Z97-D3H

Here is what I did

1. Manually set the CPU uncore ratio (aka CPU cache ratio) to 32
2. Set VccIN (aka VRIN) to 1.900 V and set VccIN LLC to High
3. Leave the DRAM ratio, timings and voltage to Auto
4. Start tweaking the CPU ratio and Vcore


I was able to stabilize 4.3 GHz using 1.325 Vcore. My chip is a poor overclocker. Many members here are hitting 4.5 to 4.6 GHz using ~1.3 Vcore

Try it out

Hi,

So far i have pushed this to 4.6ghz at 1.424v but it seems to high. how much voltage is to much to push? 1.5v - 1.6?

edit: to clarify i'm asking if push over 1.5 volts would be considered suicide running it.

Welcome to OCN!

For Haswell chips I think it's best to keep them at 1.35v at the most.
I believe it's regarded as the max safe voltage for these chips.

Check this guide by Darkwizzie.

OCing Common Sense
You up the vcore slowly. You don't go from 1.1 to 1.2 to 1.3 to 1.4v just like that. Maybe you can start at 1.2, 1.25v but that really varies on the stress testing method. The problem with going straight to a higher voltage is, you may overvolt and use a setting that is less than optimal for stability (not proven) or temperature (obviously proven). Say you start OCing by going to x45 and using a whopping 1.45v straight up and it works. If you don't back down that voltage and you leave all that unnessary voltage about, you will not only cause more heat than you need to, you will decrease the longevity of the CPU for no good reason. At minimum I suggest going from 1.2 to 1.25 to 1.3 to 1.35 to 1.4. Any larger jump I think is completely useless for attaining a good, fine voltage.

When you plug in a higher voltage for the first time or use a stress test for a first time, eyeball the temperatures. You can go from 70C in x264 to 100C in Linpack quite easily and if you run off to make a sandwich, you risk hurting the CPU when you could've watched the temps for the first 10 seconds of the stress test and avoid this.
