New PC
 

My Q6600 pc has finally given up. It has served me well for the past 8 years. RIP:cry:
I had been holding off getting a new pc until I could get AVX512 but can't do that now.

Here is the build I am thinking of:

i7-6700K £281.94
ASUS Z170-K £109.99
Corsair Vengeance LPX 16GB (2x8GB) 2400MHz DDR4 Memory £79.99
Fractal Design Define R5 £99.95 - have been impressed by my dad's R3

I will also need a cpu cooler. I am not too fussy although I want long lasting and quiet. Probably a fluid dynamic bearing. Any suggestions?
I currently have:
550w 80+ Gold modular psu
750Ti GPU
~250GB ssd
2TB SSHD

Any suggestions for improvements/cooler?
I want an i7 due to nfs sieving running faster with hyperthreading. I will also be doing a lot of LLR tests. Hopefully more of this will fit in the larger L2 cache.
In a few years I will probably upgrade the ram speed/capacity.

In addition to this I will be attempting to move over an upgrade windows 10 license. Does anyone have any experience of this? I think it changed somewhat after the anniversary update.

Start with 3200 or 3000 MHz memory. It will make a difference. That CPU is memory starved, especially if you overclock it.

You can't go wrong with a Noctua cooler.

Good point. I would hope that most of what I do will fit in the L2 cache but there will be occasions where it won't. I am not sure how I didn't notice that the 3000 memory isn't that much more. 3200 is though.

Slightly reluctant to have memory at 1.35v. Hopefully it will run at lower. Want a long lasting memory controller.

The shop I use only sells one type of Noctua cooler and it is £55. I was hoping to be <£30.

Consider replacing the PSU with a more efficient version (Titanium or one notch lower). Depending on your electricity prices and power consumption, a new PSU could pay for itself in a couple years especially if you can pick one up on sale.

If you don't need a lot of drives, you may also want to consider the Define S. It has better airflow and it's cheaper. I recently built a system in one.

Right now I would prefer to not spend money that I don't have to. I realize that this would be sensible in the future. I wouldn't spend so much on parts such as the cpu and motherboard apart from the fact that long-term they would be expensive to upgrade. I finished an MSc less than a month ago and am still searching for a job. In a few months finances will improve.

A strong possibility. I will look at reviews.
I do plan to have more drives in the future. I will be adding another 3.5 inch drive for backups and quite possibly a dvd drive(my current one is ide and is 10+ years old). That is a little tight for me as I would always want a spare slot for if I was changing drives.

The Define S doesn't support external drives.

[QUOTE=Mark Rose;444153]The Define S doesn't support external drives.[/QUOTE]

That is probably a deal breaker. I don't use CDs that much but I do want it convenient.

Shop around: there are some great deals on ebay :smile:

Concerning your PSU with Gold rating it is already relatively efficient. Dumping it for a Platinium would make sense only if its capacity is not enough at the moment (the peak efficiency is round 50 % of the nominal capacity.) At the moment you have 91 W for the CPU, less than 75 W for the chipset, fans, disks and the permanently occupied USB ports... On the NVidia site I see 60 W for the GPU and a recommendation of 300W minimum for the power supply (400 W on the Gigabyte site.) The total of your needs would be less than 250 W and this means your current PSU is sufficient.

If you "don't use CDs that much" you could try an external USB DVD or even blue-ray reader.

If you want to stick to 1,2 V for your memory 2800 MHz will be the maximum frequency. Like other posters I think you would be better off with faster memory even if its voltage would need to be 1,35 V.

Currently trying to get this pc stable. I am getting iterations being zeroed every so often in a torture test. Does this mean memory or cpu? It seems a strange error to me for instability.

Go with BIOS defaults. Test. And then gradually introduce higher clocks for the RAM, testing at each stage. There might be some BIOS setting that gives you stability -- I am trying to remember -- adaptive that's the one :smile:

I should have pointed out that my ram is currently at 2133. I am aware that I will probably need to up the voltage of the memory controller to reach 3000. This is on bios defaults apart from switching on vt-d and vt-x which I use for virtualbox.

2133 is quite low -- good. Try "adaptive" for you CPU.

Added 9.76mv to the cpu as an adaptive offset.

Let us know if it is prime95-mprime-torture-test stable now. If it is you can start to test with higher memory clocks.

Could be a decent wait. It took an hour last time.
What temperature would you be expecting with a nh-u14s cooler? The intel extreme tuning facility is reporting 69C currently. My old cpu would have hated that.

69C seems reasonable considering the machine is running flat out at 4GHz -- just keep it dust-free :wink:

Failed again. Now got 19.5mv added

Is there a way to use just "adaptive" without an offset?

Also turning off turbo might help.

[QUOTE=henryzz;445694]Failed again. Now got 19.5mv added[/QUOTE]

Seems to be failing much quicker at +19.5mv. 10 minutes rather than an hour.
All of these failures have been zeroed residues rather than the expected value.

Have you run memtest86+?

[QUOTE=paulunderwood;445700]Have you run memtest86+?[/QUOTE]

It survived a couple of hours of memtest86. I am currently trying -20mv as most readings I have seen on the web seem to have a lower voltage for a 6700k at 4Ghz than 1.28v(before avx boost). It has lasted a good while although the ambient temperature is a couple of degrees lower currently. I have previously reckoned that that has a negative effect on the pc.

Maybe this is related to that user who keeps submitting false positives (or more curiously, "composite" results with a zero partial residue).

Seems like Prime95 would catch a zero residue at some interim stage and say "yeah, right" rather than continue on and eventually check that in as the "result". :smile:

well it depends if it hits 0 just at the end then there's nothing but the end result to detect if it hits before in theory 0^2-2 = -2 so it's no longer 0. and if it gets past the negative 2 it stays at positive 2.

4 hours of small ffts passed on -20mv. I think another line of attack is needed. Either memory voltage or system agent voltage needs to change I think.

Another 11 hours of memtest86 passed overnight.

[QUOTE=henryzz;445789]Another 11 hours of memtest86 passed overnight.[/QUOTE]

Is that at 3000 MHz?

So you have a stable system now?

BTW, do you run with case side on?

Did you see this thread, specifically post #62:
[url]http://www.mersenneforum.org/showthread.php?t=21485[/url]

BinaryKhaos' problem was solved with microcode update. There might be a full BIOS update release by now.

XeniaRick's problem turned out to be a broken pin on the cpu.

The i7-6700K is a 4.0 GHz [U]SkyLake[/U]. Could this be causing some of the issues?

The question is which microcode version is needed. I am on version 0x84 which is later than then for asus. Whether it is late enough I don't know. I don't have time to look through the thread in that detail currently. I have just updated the bios although it is the same microcode version.

All recent test have been at 2133. Case with side on although it is the same without. It is stable apart from prime95 I think.

Have you tested with turbo off? :smile:

[QUOTE=paulunderwood;445843]Have you tested with turbo off? :smile:[/QUOTE]

Next job once I am back from interview. Assuming that it fails with the updated bios.

[QUOTE=henryzz;445844]Next job once I am back from interview. Assuming that it fails with the updated bios.[/QUOTE]

Henry, good luck for the interview.

After updating the bios it just passed 7 hours of blend which is a record. It is cool in the room currently which could have helped. Hopefully this means problem solved. I wish I had just done this update ages ago.

[QUOTE=henryzz;445858]After updating the bios it just passed 7 hours of blend which is a record... [/QUOTE]

I'm going to torture-test the HP after I get it all set-up and running. It says run it for, at least, 24 hours, so that is what I will do.

Seems to be running stable with the memory at 3000 now as well. Need to watch it when applying the spd settings. It also did several cpu optimizations which included putting the TDP limit to max. With Prime95 28.9 running full tilt with the memory at 3000 the cooling couldn't cope with this. I have put the limit back to 95W.
I have done this testing with it around 26C ambient for a bit. The usual max is 23C.
I will leave it overnight like this and then will start reducing voltages. It would be nice to stop it TDP throttling.

[QUOTE=henryzz;445878]I have done this testing with it around 26C ambient for a bit. The usual max is 23C.[/QUOTE]

You must be using something exotic to cool this with. 23C to 26C is in the 70's on the Fahrenheit scale.

"ambient" = surrounding temperature, i.e. room temperature. I hope it's in the 70s!

[QUOTE=VBCurtis;445887]"ambient" = surrounding temperature, i.e. room temperature. I hope it's in the 70s![/QUOTE]

Ambient. I had just got home from a long work day. I saw but I didn't see. I've never gotten accustom to the Celsius scale. 0°C freezes water and 100°C boils water. However, I look at it every day on my display. I have a hardware monitor app that displays CPU and GPU temperatures. It's all in Celsius. Everything on this idles at around 40°C. When I see that, I know all is well.

I hope this isn't taken as my telling you how to chew gum, but I would highly advise you run DCs during this experimental period (if you aren't already).

Just because a machine doesn't crash doesn't necessarily mean it is producing good results. This doesn't matter for gamers (or, frankly, most users) but it does matter for compute.

celsius is basically coding of 0 = 32F and +1=+1.8F

Once I have gotten it to where I think it is stable(with lower voltages) that is my first task.

I have been surprise by how low VCCIO and the system agent voltage could go.

Defaults after applying XMP profile
DRAM: 1.35v
VCCIO: 1.125v
System agent: 1.2v
CPU: Default

The system seems to be stable at:
DRAM: 1.30v
VCCIO: 0.95v
System agent: 1.00v
CPU: Default-0.03v

More testing is needed especially for the CPU voltage. My VCCIO and System agent voltage seem lower than anything I have seen online for >2133 memory. Away for the weekend so will probably get back to this Sunday evening/Monday.

Where could I find information on the microcode installed? I am running an Asus Sabertooth Z170 Mark 1, with a BIOS built 11/29/16. I have looked in the BIOS, CPUZ, etc, and there are parameters I don't know, like EC1, EC2, and MEV. None of them have a form like 0x84. :confused2:

I get it from the Intel Extreme Tuning Utility. It does ring a bell that I had it before installing that but I can't figure out where.
There certainly has been issues needing microcode fixes in these skylakes. That hasn't been the only issue for me. Going from the preinstalled bios to the latest didn't upgrade the microcode, however, it did make it stable.

Huh... I thought for sure CPU-Z had it but I just checked... if it does, I didn't spot it right away.

[URL="https://technet.microsoft.com/en-us/sysinternals/cc835722"]CoreInfo[/URL] from Sysinternals will show it. Something like this (from a Xeon E5):

Thanks to both of you! The information is much appreciated! :smile:
