***Haswell -E Owners Thread***

sometimes hardware monitor takes a while to launch with my 5820k, give it a few minutes and it normally opens and runs fine.

Down to SPD detection of I remember rightly , turn that off inside HWmonitors config file and it will open far quicker with all the relevant information still shown , CPUz has same issue and is fixed same way .

I don't know how the Asus boards with the OC Socket compare with the OC Engine on the MSI, as that may account for something... then again, you could just have a dog of a chip. That said, I've heard Prime 95 is a rather harsh test, and you will never see that kind of use in real world. I'm sure I've even read some people suggesting it's not best suited for Haswell-E anyway. I have my 5820k at 4.4 (Asus X99-S), but I've not tried it in Prime 95, only AIDA64, and it seems fine with that. Give that a go and see if you have the same stability issues.

I'm sure these chips shouldn't be put through prime 95 due to it forcing higher voltage then the user Inputted value potentially killing it or the VRMs on the motherboard , AIDA is your best bet My 5820k will only be 4.4 stable @ 1.338v ... Any higher it's unstable regardless of how much Voltage I throw at it , my cache will only do 4100mhz although the I havnt messed with SAvoltage much so it's my next port of call .( x99 pro )

You won't, that's what makes it such a great stability test. Intel have million of pounds in hardware to test every part of a chip the best we users have is software like Prime95.

There's really no limit on how much a CPU can process if it's built/cooled properly (I say that because IB/HW have severe heat problems due to TIM issue and things like mobile devices are usually insufficiently cooled due to size). A CPU that failed Prime95 due to a calculative error the likes of which you get when overclocking would never make it out of the factory though, regardless of the amount of load it's under.

Can you imagine if Intel shipped processors to scientific industries who are going to use them for massive computation and warned them that they can't use it to its full potential? they have to be built for the worst theoretical conditions.

Personally I would never run Prime95 (or LinX) on these Haswell chips, they really don't like it.

The old generation chips could handle it but these 22nm get too hot too quick. No point in cooking your chip for unrealistic stressing.

Stick to Asus Realbench and Aida64 stress test, plus lots of BF4! ;)

This is hog wash, do not recommend users to use Prime 95, especially v28+

Temperature only plays a small factor, it is the current and the current alone that is potentially damaging especially for prolonged periods of time.

Because these tests invoke synthetic algorithms that call apon the AVX 2.0 instruction set, certain overclocks can pull in excess of 400W. This is both too much and damaging to the CPU (degradation). There are NO known programs that hammer the CPU with AVX instructions the way Prime does, in in fact it is Prime alone why Intel invoked the need for additional voltage when these instructions are used.


Hence Haswell + Prime95 = NO

On top of this Prime only tests a small portion of the architecture, which is why people who have been and done that will know that you can be Prime stable and still experience problems when running other rendering or daily tasks. Current and heat does not equate to more strain across the logic circuits of an entire cpu architecture.

5820K, Asus X99-S and 16GB of Crucial DDR4 have been ordered! I will be joining the club very soon!

Anyone got any basic settings to start overclocking at? Or are the Asus presets quite good?

Same here, in fact I could get away with slightly less volts if I want to.

1.275v is rock solid for me at 4.5Ghz.

@ketma What voltage are you giving your cpu ring (cache)?

Default - I have not changed that value.

I tempted just to dump this chip and try another, I have raised my request with Intel and all I have to do now is ring DHL for collection.

Cool thanks. From what I've read, 1.3V is the maximum safe VCORE right? Anything above that is not worth it for safety.

It's not as cut and dried as that.

If you have good cooling you can go above 1.3 quite happily. But we're talking about a decent liquid cooled setup at those sort of voltages IMO.

I run my 5930k @ 4375mhz with 1.275v

And that can auto-underclock still when not in use and go in to sleep state.

Could not agree more with these statements, and I am pretty sure 8Pack would also concur - and he knows a thing or two!!!

That's where your going wrong. Don't be afraid to up the volts on the cache.

Try 1.275v-1.3v. I reckon that will help stabilize your chip.

That should be good for 3.5-3.6Ghz for your northbridge speed as well.

Ok, followed your advice...just changed this setting to match the vcore, so ring voltage = 1.275v and just set the multi to x42 (expecting it to fail)....booted into windows no problem and I ran the XTU stress test for a very short run which was ok.

Going to try 44x now...

Really appreciate this assistance, thanks.
 
Tried 44x and wouldn't boot into windows (BSOD). Increased ring voltage to 1.300v and still no joy. Back to 42x and 1.275v as I type this....any other thoughts?
 
I have an odd thing with mine, where it just gets stuck on my Asus boot screen now and again, maybe 1 out of 10 boots, although sometimes it will happen a few times in row. No error message, just gets stuck on the Asus logo. Is this likely to be due to it not liking the OC, or something else?
