post #701 of 858
My 4670K wont downlock to 800MHz even with offset voltage, C1E, and SpeedStep. Using a Z87-A board. Does anyone have any suggestions?

edit - the voltage drops but the speed doesn't... even with default BIOS settings and Asus MultiCore Enhancement disable it still wont clock down to 800MHz :/

Assuming that you're using Windows, what's your "Power Plan" set at?

If it's set to "High Performance", try setting it to "Balanced" instead.

It seems haswell can be as much as 25% faster then ivy:

Look at moosehunter results. This is in gc/wii dolphin emulator, which like all other emulators, is very cpu dependant.

Haswell CPUs are a poor choice for desktop gamers. Here’s why.
Quote:
Intel’s 4th Generation Core architecture, known to you and I as Haswell, has finally landed and with it the new processor for your next gaming PC has surely arrived. Hasn’t it? Well, if your next gaming PC is going to be a laptop then that’s probably a rather effusive yes. If you’re a desktop gamer looking for more processing grunt and some hefty overclocking prowess from this new architecture, however, you’re probably going to be rather disappointed.

If you’re already rocking a decent quad-core CPU from either the last couple generations then there is very little reason to spend the money upgrading to one of the new range of Haswell processors, especially as you’re going to be looking at picking up a whole new motherboard too.

Yes, it’s new socket time. The new set-up chops out five pins from the LGA 1155 socket and shuts down backwards compatibility in the process.

Haswell is all about power-saving and improved integrated graphics. In other words, the 4th Generation Core architecture is built for mobile computing, not the humble ol’ desktop where we wont see the funky new Iris Pro graphics except in BGA trim.

On the desktop things haven’t really moved on since Sandy Bridge arrived on the scene many moons ago. And to be honest if you’re sat on an i5 or i7 Sandy Bridge chip then you’re arguably better off sticking with your current CPU/mobo configuration and spending the cash on something like the Nvidia GTX 770 if you’re after a gaming boost.

The top i7 desktop Haswell isn’t worth buying a new mobo for.

We’re still talking about a maximum of four cores, with eight threads on the top i7. And the top clock speed of 3.5GHz is nothing new either. They are, in general, ever so slightly quicker compared with the existing Ivy Bridge chips. But not in any meaningful way for gamers.

If you’re after serious computational power from your desktop though, Intel might argue, they have the beefy LGA 2011 socket and its Extreme! six core chips. You can even strap an eight core Xeon into one of them too. But that is actually quite damning for the new desktop generation considering the current top end desktop chips in the LGA 2011 range are all still based on Sandy Bridge, with the Ivy Bridge E update set to arrive around the Autumn (Fall for my US chums). Who knows if the Haswell architecture will ever get an Extreme! update.

And then there’s the overclocking performance of the new Haswell chips. I know most people probably wont spend the time to see what extra performance they can get out of their top end components for fear of frying expensive silicon, but modern chips are generally robust enough to cope with whatever we can throw at them.

I was then hoping for some good results from the 4th Gen chips, but fearing the worst. From Sandy Bridge to Ivy Bridge the overclocking performance dropped, and in the transition to the Haswell architecture that performance has dropped again. There also seems to be far greater variance between chips too. I’ve spoken with various system integrators and they were all struggling to figure out where to position their overclocked Haswell rigs.

We’re looking at around 200MHz lower clocks than the equivalent overclocked Ivy Bridge chips, even using decent water-cooling CPU blocks.

so 3930k and 3820 are sandy bridge so they are ok in regard to TIM unlike ivy bridge 3570k/3770k?
lets just hope the 4xxx ivy bridge e is not crippled like ivy bridge is

thank you

The ivy xeon's seem to run fine unless they go with something else for the Extreme line up I don't see any problems there.

Well, for one, the title is plain BS.
