Maybe worth trying a lower Cashe ratio. Remember it is the temperature that prevent higher overclocking for you. But it depends on how much higher you can increase multi.

 

I think that is the more likely possibility. Maybe you're stable at -160mV?

 

Thanks man! Seemed to have worked favorably. I found that a cache ratio of 12 doesn't seem to hurt any performance and I was able to further undervolt the cpu cache to -250mv and shaved off a few more degrees!

 

If I had to guess, I'd probably agree that it is too much negative offset and the lockup is from not enough voltage. Crysis 3 is more demanding than most games. Should be easy enough to find out by reducing the offset.

 

Off Topic: @Diversion - is Hurricane Matthew causing any problems for you, or did you and your family leave town to be safe?

 

Thanks for asking.. We're in Jacksonville and got hit really hard but I live on the Southside of Jax where it was pretty safe.. Some scary gusts rattling the windows but nothing crazy happened here. It's still crazy outside but luckily power never went out! The beach area has at least 3-4 feet of water in businesses, etc.. I feel really bad for everything that has happened .. We're getting the bottom of the hurricane's outer bands now.. Sigh.

 

Awesome. Glad to hear everyone is OK.

 

Thanks.. so what overclock does your P750ZM do with the 4790k? I have a 4790k desktop that can do 4.7ghz stable with Prime95 AVX.. Tried for about a months time trying to get 4.8ghz but I think my 4790k is just bunk.

And how are your temps?

 

Well, this little 15 inch laptop with a puny unified heat sink struggles to stay cool above 4.3GHz for daily driver clocks. At 4.3GHz it manages to stay cool enough to avoid thermal throttling under 100% load. But, it benches great at 4.8GHz on AC cooling. And, I have validated it with CPU-Z at 5.0GHz. Heat is the biggest challenge with any Haswell CPU. I set things in the BIOS for 4.9GHz and then use ThrottleStop to tone things down in Windows with four separate OC profiles, 4.3, 4.5, 4.7 and 4.8. The only one that I use all day long is 4.3GHz. Before I delidded it and put the Liquid Ultra on everything, it ran warmer stock that it does now at 4.3GHz. The funny thing is the GPU half of the heat sink does a truly amazing job even though the CPU half doesn't.

I ran the 6700K in the Sky X9 review unit and the 6700K in my P870DM-G at 4.8GHz all the time and the temps were great. I'm eager to get back to that with a P870DM3.

Otherwise, it's a really decent little machine apart from the wimpy cooling system. I always do my serious benching on AC cooling, especially where GPU is concerned. These NVIDIA GPUs are too spendy to let them fry themselves and the AC cooling works perfectly. Below are some of my benchmarks with the P750ZM. I need a better GPU than 980M for benching, which is one reason I am thinking about the 16L13. I can't put a 1070 or 1080 in this one, and the prices they are charging for Pascal GPUs is so retarded that it would make more sense to just get a new machine for only a little more money.

Since I don't know your exact experience or what kind of loads you tend to test with but at 4.2ghz right now i'm not going over 74c tops in most of my benches except for Prime95 Small FPU (AVX) which always is my max heat benchmark and continues to be.. Everything else I test doesn't use AVX instructions so it levels out between 70-74c with my max undervolt.

I feel that's pretty cold for this machine. And it's ultra silent during all tests. The only time the Barebones makes any fan sound is when you play a triple A game and that fan sound is very quiet even then.

 

I always bench with max fans. I'm more into the drag race style of benching than I am the baja style, so I don't ever use Prime95 for CPUs or Furmark for GPUs. wPrime 32M and 1024M and Cinebench are the main CPU-only benchmarks that I run.

Spoiler: 4790K CPU Benchmarks

 

The processor is almost never taxed more than a fully Wprime 1024M stress test, so this benchmark is a useful one. Newer Prime95/Linpack isn't normal processor workflow.

 

Gotcha.. I think i'm too wound up on Prime95 temps when they represent literally no other load temps for any real life usage. I need to stop worrying about Prime95 then I guess lol.. Since temps are quite unbelievably low in everything else.

Here's my wPrime 1024 max temps with auto fans (Never can hear the fans during this test):


And with Max fans:

 

Well then good news for me, 80c tops it looks like for me with 4.1ghz locked all 4 cores. 4.2ghz is doable as well at 81-82c. Using Auto fans (which is my preferred way to use my machine).

 

You have a headroom for higher clockspeed if needed with forced max fans. A nice feature not all laptop models have And remember TS also has its own bencmark test. You can also see max power draw in TS, If you click on package power tab.
I'm glad there is more than Clevo who have socket i7. Thanks for showing. +rep

 

Lol, thanks! Man, i'm really fine with the way she sits as is.. So much faster than the GT62 with 6700hq.. Really happy with this machine!

 

Yeah, I'm happy you choose a machine with socket hardware http://forum.notebookreview.com/thr...ger-np9172-review.795901/page-8#post-10358909

And forget 6700Hq
http://forum.notebookreview.com/thr...6820hk-for-undervolting.796533/#post-10358077

 

Lol, you do indeed have a hatred for BGA! I don't really have a hatred per se but I am glad to be in a socketed machine because it's WAY MORE FUN. And the flexibility is ridiculous to be able to downclock and save wattage and go crazy and OC. It's a do-it-all setup and I love that about it.

 

By any chance, did you check the minidump? I just got two BSODs... I thought it was due to my undervolt, but in fact it was due to the Killer Network Manager. Installing the newest version from their website fixed it.

 

So, I did some benching to show the power draw for comparison against the 16L13 in case anyone is curious (or maybe a point of reference for myself later in the event I end up owning one)

P750ZM @ 4.8GHz and single 980M at 1530 core, 1800 memory, 1.287V on GPU... System power draw was 369W max according to my UPS... peak CPU 189.4W and 204W peak from the 980M


Benchmarks are in the spoiler that produced the power readings.

Spoiler: Tonight's results

Another round for the baby beast 4790K and single 980M...

I'll do some Prime95+Furmark readings once I dial in my OC. It's doing so well at 4.0 GHz, I'm thinking of pushing to 4.2 GHz. Greed is taking me

 

Let it take you! The addiction will control you, and it's awesome.

 

That's why I like running with Hyper-threading disabled, disable those HT cores for a 10c+ reduction in temps.

Has anyone done any side by side comparison's in a wide range of games between the GT62 1070 and the 16L13 1070 to see if the 91w CPU 6700k/6600k improves gaming performance?

I think it's only going to show lower CPU utilization in most games, no added FPS. High CPU demand games should show a difference, but it would be nice to see how much.

 

I never blue screened. Screen went blank and had to hold power to reboot :/

 

So much more performance in my rendering/encoding apps though with 8 threads. For gaming and anything else i'd be okay with 4 threads though.

 

How do you easily cleaning the GT62 surface guys?
I know that this metallic surface is better than rubber ones on the Asuses but ...it still catches all my fingers on..mainly around the keyboard.
Also using some breath/polish method?

 

So I will see soon on people selling or teaching on how to mod additional heat pipes. Or maybe GPU heat pipes from msi will do

 

Mr. Fox I think the firmware handles the fan speed so that cpu speed can be pushed up more than 4.0 ghz. It would really help a lot if you can soon mod the bios and firmware. And you'll get a thousand credits for this including donation

 

Having looked into this barebones beast thoroughly I'm wondering which is the best vendor to purchase from. Cyberpowerpc prices are way more reasonable compared to eurocom if you want it to come ready to run and not buy ram, Windows 10 separately.
http://www.cyberpowerpc.com/system/Fangbook_4_XTREME_VR_200_Gaming_Laptop

Are they reputable? Do they offer any discounts at either reseller?

Best price I could find:

 

Damn microfiber towel, dry with other end. Don't use polish or any cleaning products.

 

I hope I am able to help, but my first priority is getting a P870DM3. If I get one of these machines it will have to be after that, and I will have to sell the P750ZM for enough to cover the cost of purchasing one, so it is uncertain what will happen or the timeline. I am very interesting in getting one, but it might not happen on a short timeline. When the time comes I will work with @EurocomTechspert on the purchase.

 

Take your configuration and quote to Eurocom and see if they are able to match or beat it.

Both companies have been in business a long time, but my personal preference would be to buy it from @EurocomTechspert rather than the other place. Not because of anything bad on CyberPower's part, but I know the folks at Eurocom and I have never done business with the other place before.

 

I did it...I went to 4.2

It took a surprising amount of voltage... The CPU holds 4.0 GHz at -160 mV, but in order to be stable at 4.2, I had to decrease my undervolt to -80 mV. The downside is that it's now hitting 84 C when I run Prime 95's small FFT test . Hopefully the temps will drop a bit when I redo the thermal paste.

 

Remember, the cooler you can keep it the less voltage is required. They go hand-in-hand. More voltage requires more cooling and added heat requires more voltage. The key is cooling.

Have you delidded? Are you using Liquid Ultra?

Edit: Stop running Prime95. What are the temps like in Cinebench, 3DMark 11, Fire Strike, Vantage and your favorite games? I bet the temps are lower.

Unless you do a ton of video editing and rendering or something similarly demanding, Prime95 doesn't accurately represent the kind of load most people see when doing overclocked activities for pleasure. The nice thing about overclocking with ThrottleStop is you can change clock speeds with keyboard macros on the fly to fit your situation.

 

I'm not delidded, and I'm still using the stock thermal compound... I don't think I will delid, but I will definitely redo the thermal paste.

Prime95 isn't the most representative test, but I like to include it in my testing as a metric for the absolute worst case scenario. My CPU hits 81 C during Firestrike.

 

Got some kill-a-watt wall power draw numbers for you guys...

i5-6600K @4.2 GHz (-80 mV)
GTX 1070 (stock)
Max fans

Idle: 27 Watts
Prime95 small FFT + Furmark: 215 Watts

In my case, the 230W PSU might be barely adequate, but if I ever delid in the future and push higher than 4.2 GHz, it would probably not be sufficient. Not to mention, I haven't even touched GPU overclocking yet.

 

81°C is fine. If your not delidded and running stock paste and seeing that as a max temp at 4.2 that is actually pretty decent. There's room for better, but you could run it like that as long as you want to with no issues.

Yeah, 230W is really cutting it close. Should be fine for people that don't overclock, but I'd never purchase one without the 330W AC adapter because I never leave things stock.

 

The new Acer Predator 17 BGA machine with the lot weaker 6700Hq and 1070 reviewed from Notebookcheck, used whopping 223w(Everything stock). Of course the flimsy 6700Hq can't go over @3.1GHz on all 4 cores, and a stronger processor will need more power. Never a good idea to max out any psu. I killed 2 of my 240w Psu's with benching my Aw17(4930mx-780m). 230/240w psu isn't good enough for any systems with a high end graphics. Even crap with a low entry BGA i7.

 

Since I had both the GT62 and Barebones now.. I haven't done a super wide range but everything I played were identical performance.. World of Warcraft may be a up to 10 fps more on the barebones since the game leans on the CPU a lot.

Otherwise, Crysis 3, Witcher 3, Overwatch off the top of my head were identical.

 

I had no idea maxing out a PSU could kill it... I thought it would either start drawing from the battery, or shutdown the system

I am glad I went with the 330W the only downside is... well look at the size of it

On the left is the 330W, on the right is a 180W. Standard deck of playing cards for reference.

 

Oh" yeah, you can kill a flimsy Psu And be happy. Bigger the better said... Aka no downsides with bigger toys Flimsy weaker psu is the normal for weaker hardware. See Chromebook's, Dellbook's, Applebook's and similar.

 

I've been using 330W AC adapters (single and dual 330W) on every laptop I have owned for quite a few years now (M18xR1, M18xR2, Alienware 18, P570WM, P750ZM and P870DM-G). It does not seem that big to me, but I am used to it. Not a big deal in terms of size or weight, but totally worth it. I do get a nice chuckle out of the reactions of people that are used to the puny little AC adapters that come with Dell, HP, Lenovo and other wimpy laptops. The first reactions are priceless. Even more so when they see a dual 330W setup for the first time.

 

As I mentioned in the other thread:

I've been in close communication with Svet about unlocking/modding the 16L13 bios.. He has a suite of tools he hand-crafted/and or coded himself he says he can use to work on the dumped BIOS from my unit. Downside is there's no guarantee yet and that he will have to spend 5-6 hours cooking something up for us.

I am funding his time personally and if @Talon and whoever else want to help push a donation to him, that would be much appreciated.

A few features added to the BIOS would be BIOS overclocking of the CPU including BCLK (which is amazing). Among many other useful enthusiast type mods found on desktop tuning motherboards.

 

I would love a 330watt PSU but getting one al la carte from Eurocom is about $165. If you or anybody else know where I can get some cheaper, I would appreciate it! I've been finding a lot of 330watters with the barrel plug.. But the 16L13 needs the 4-pin plug to the laptop side.

 

The Clevo 330W AC adapter works if my understanding is correct. The barrel plug type are for Alienware. The Clevo 4-pin type that works on MSI is exactly the same adapter as Alienware, but typically sells for $50 to $100 more than the Alienware version for some silly reason. (I purchase several brand new on Amazon a few years ago for $30 each.) There are not many good deals to be found for those with the 4-pin Clevo connector on the end. You might find one for sale in the NBR Marketplace. That's where I bought my last one.

$165 is the going rate for a new one from a Clevo vendor. http://rjtech.com/shop/index.php?dispatch=products.view&product_id=30186

You could buy an Alienware 330W, take it apart and transfer the cable from your 230W AC adapter. I have looked everywhere (places like Mouser) and cannot find a replacement 4-pin connector that fits. The pin spacing is correct, but the male/female part is the exact opposite of what it needs to be. If a replacement end connector was available one could easily make an adapter dongle or replace the tip on an Alienware AC adapter.

 

Sometimes you can get a used/new 330w psu for a decent money in the forum marketplace. Have your eyes open for this

Edit. Damn @Mr. Fox you where first

 

I don't see any in the Marketplace.. Do you think $165 is fair for it? It'd be a PSU i'd keep forever probably lol..

 

Yeah, not too bad. It's $100 more than buying it as an option with a new machine, but now you would have both available. The price new has gone up about $40 in the past two years. Not sure why that is. It's exactly the same product that has been around for at least 5 years, so the price going up must be based on demand... just because they can.

Edit: RJ Tech and Eurocom price is the same as HIDevolution: http://www.hidevolution.com/330w-laptop-power-adapter-for-evoc-p775dm-p870dm-models.html
