Haswell In A Few Words & Pictures
MaxPC has a very nice intro to Haswell for those trying to get up to speed quickly with Haswell. Good concise write up with a few informative tables but do note the misinfo about the USB3 bug on pg 4 though.
Haswell Review | Maximum PC

Seen this one yet?

Enjoy!

Too lazy to repeat the same discussion so will simply quote it here....

From
Blue Forum discussion

Intel trolled the PC makers (and us) and got their(our) hopes up! :hammer:

Retail Versions of Intel Core i “Haswell” Are “Hotter and Slower” Than Expected – Report - X-bit labs

Shrek and Mac:

Is this true from your experience with Haswell so far?

Retail Versions of Intel Core i “Haswell” Are “Hotter and Slower” Than Expected – Report - X-bit labs

Yes and no

According to manufacturers of factory overclocked PCs, commercial versions of Intel Core i7-4770K cannot remain stable at speeds achievable by samples of the product. Intel admits: overclocking results are not guaranteed.

Yes - apparently there are fantastic 5GHz@1.20V ES chips around and maylyn/lennardeah has/had ever his hands on one. But we have seen this before with the previous gens too eg. Ivy - anecdotal stories of ES hits 5 GHz easy...

"PCs based on pre-production [speeds] of 4.5GHz have had to be dropped to 4.3GHz because of a lack of stability in retail parts,” said a representative for another PC manufacturer.

No - from this forum postings, present local batch with Shrek/longsiew/mine hitting 4.5GHz easily but other overseas batches are having lots of trouble even reaching 4.5GHz.

Another concern for PC makers is that retail versions of Intel Core i “Haswell” chips when overclocked are around 15°C hotter than pre-production samples...

One reason why I was so sceptical of 4.5GHz@60C so easily... got to try it yourself and then say that again. Overall, mine runs relatively quite cool but there are these transient sudden spikes which pushes the max reading to near 90C under LinX AVX which makes it look worse than what it really is.

In the end, Haswell >> Ivy anytime for me cos it o'c more stably while Ivy o'cing can be so fickle with insidious WHEA warnings.

Go get one and experience it for yourself, it's actually quite a nice solid chip with very good mobos around.

Probably the integrated voltage regulator causing heat issues. Previous CPUs doesn't feature that. I'd be quite concerned to see my cpu temp reaching 80+C and above.

The table from Max PC shows that haswell is better than a similarly clocked ivy and higher clocked sbe. It can also match the lower clocked 6 core sbe well.

Regarding my h87 request, doesn't matter which brand bro.

 

[MacClipper]

Yes, FIVR is hot.

As for the H87, let me go ask after the PC Show.

Just changed to a i7-4770 with MSI Z87-GD45 Gaming. Big increase in x264 performance - About 40% faster with 480p videos. Still doing testing.

 

[Cryogenist]

Just hooted the 4670k + MSI Z87 GD45.

Will report my OC results soon.

 

[MacClipper]

... I'm looking forward to massive undervolting.

May not be really massive enough but this post is for you.

- for the parsimonious, the green Gaia lovers and oh yes of course, the SFF guys too

Setting Vcore in negative Offset Mode so the idle Vcore is now ~0.6V only with max. load DTS at 60C running LinX AVX.

Welcome to the Klub Haswell!

Yes, pls post your findings and screenshots too.

Thanks! Now my CPU running at 0.995v on average. It sometimes jumps to 1.042, I'm guessing that's the adaptive voltage thingie in action?

Another thing I'm noticing is that the CPU temperature sensor is very wonky... It jumps very erratically, but within a range. So unlike my 2600K where the temperature changes gradually.

And as I had just said, welcome to Klub Haswell! lol

Yeah, Haswell and Ivy chips are like that. Super fast transient temp swings up and down to the extremes so quite "normal" behaviour actually.

Thanks MacCliper. I'm actually using the Intel Extreme Tuning Utility. It exposes a few other options like Cache voltage offset and Digital IO offset. Is it ok to touch those as well?

 

[MacClipper]

If you look at the screenshot in post #391, these options are also present in the Asrock BIOS as well.

imo, no need to touch them unless you really need to. And best, read up the Asus Haswell guide for a more complete intro to overclocking.

Wait a minute, you are using a non-K chip so what are you doing with voltages huh?

 

[junialum]

Undervolting is very tempting for me. My i7 920 really eat a lot of electricity.

Do you really calculate the monthly cost if power on for 24hrs? Would be interesting since mine is fully on...

Anyway for haswell even without undervolting already consume less power.

Hmmm? To save power what. Or do you mean Non-k chip not supposed to be able to change voltage? Mine can leh.

 

[khuin87]

Anyone know when we'll have xeon variants available at SLS?

I forgot that's your main aim... lol

Keep us updated on your final power savings.

 

[MacClipper]

For the extremists fixated on delidding, the good news is you can now get CLP direct from Amazon with their free shipping scheme.
Amazon.com: Coollaboratory Liquid PRO Thermal Interface Material: Computers & Accessories

Personally imo, the returns are usually not worth the risk/effort of delidding unless you are chasing some records.

Initial OC Report.

i5-4670K + MSI Z87-G45

4.5Ghz at 1.2V = fail
4.5Ghz at 1.25V = boot success, stress test failed

So it is considered not-so-bad chip?
