Exactly... Don't get the 4790T.., If you want, you can always make your 4790K run like a 4790T on battery and increase battery life!

 

Clevo @ CeBit 2015 a few weeks ago.

That + word from most vendors ( not resellers ) that the 15x models will be phased out in preparation for the new models. Also the P570WM is getting a successor but w/ the x99 chipset so yeah... Don't expect till Q4 more than likely around October/Early November, unless Skylake comes out earlier, unless they do special needs to big vendors then maybe August?

 

Yes at idle all the CPUs will consume about the same, the difference is the load power and how fast they will run (given their TDP limit).

 

"thin and light" doesnt mean much in meaker's case, considering hes switching from an p570wm, basically everything is thin & light *lol* whatcha getting urself, anyways? do tell

I am saddened Clevo thinks X99 is the answer! It is a socket that all possible chips will be out for it by Q1 2016. I would have preferred a skylake/cannonlake-E replacement... (potentially summer or fall of next year).

 

Agreed... X99 is one overheating monster.. I hardly expect Clevo to be able to cool the 5960X at stock in it... Personally I'm still hoping for a Skylake desktop CPU + dual GPUs however, nothing is fixed yet

 

Well guys just finished repasting with CLU. Took me about an hour to finish. I'm going to rerun the stress test that was performed before. Initial testing looks pathetic. I'm almost certain temps have drastically increased. I believe the heat sink just can't make enough contact with such a thin TIM

Edit: first run indicates temps have increased by 10 degrees. Going to disassemble again and make sure there are no air bubbles and verify alignment.

Edit2: verified the alignment with the heat sink. Also checked to ensure smooth and even coverage. Temps have increased by 7-10 degrees and am now getting thermal throttle at 4.6 ghz. Ambient temps may have increased slightly but not much. I'm at a loss. What should I do now? Just clean up and revert back to standard paste?

 

Yup, go back to standard paste!!! Your heatsink probably isn't making enough contact...

 

Exactly what I would have expected... The gap is now too large for good contact/transfer of heat. That's why later this week, my calipers, sandpaper, and some (but not all that is needed for the video card) thermal pads will come in. THEN delid, lap to a shine (all the way to fiber optic finishing paper), seal with liquid electrical tape, level cpu heatsink side to match new delid/lapped height. Watch it scream.

EDIT: I'm not suggesting you lap, etc. But a decrease of almost 0.1 from heat sink contacting the ihs is definitely a potential culprit. Other TIMs can fill the gap easier than CLU most likely.

 

Yeah what a pain. Waste of $10. I could always do the shim method and try again. But it's to the point now where I just don't care haha. It was all for fun anyways. I'll remove and put on PK3 and compare to gelid ultimate

 

Source?

 

Which ~256GB SSD + 1 TB combo is recommended for this laptop?
I know the Hitachi Travelstar 1 TB is very popular, but what 250 GB SSD is recommended to use with the Travelstar?
AFAIK the SM951 250 GB isn't available yet for purchase and the other PCI-express SSD seem to suffer from high temperatures.

 

850 pro or sandisk extreme pro.

 

thanks for your reply, since the SSDs you suggested are 7mm, I suppose I'll have to go with the Travelstar ZK1000 then? As the Travelstar 7k1000 is 9.5mm...
Does anyone have any experience with the ZK1000?


EDIT: maybe the 850 EVO m.2 is an option?

 

Evo's are frowned upon on here.

 

That has been revealed in the appropriate section

The M.2 EVO looks to be a solid drive, so I got two

 

um...why would that be? ure completely flexible with drive heights in this machine, 9.5 or 7 mm doesnt really matter dont mix this up with the P650!

You don't need to buy an m.2 drive. Only if you want the additional performance of pcie-devices.
You can install up to 4 Harddrives. 2 times m.2 and additional 2 SATA drives with up to 9.5 mm.

 

Yes, looks like paste layer is too thin and it's not contacting the heatsink. Also almost certain lot of air pockets due to spreading. But you can't put too much of liquid metal to make it thick or use pea method to eliminate bubbles - since danger that it will drip... Sadly this prevents of actually taking major advantage of liquid metals (high volumetric conductivity).

 

Yeah I thought about doing the screw method to compensate but now I just don't think it is worth it anymore. I'm just going to enjoy the batman for a while. I don't think I've stopped tinkering since the day I got it. Maybe in a month or so or maybe after AJC9988 finishes his mod and post results I'll take on a new project. For now I'm just going to say CLU doesn't work without modding and the $10 wasted can go towards forum research .

 

The P870RM is indeed a dual-SLI I forgot to mention.

 

IF that's what its even called. However since you stated "indeed" that means you now have a credible source for the name and or information. There are zero TW/CN threads/news blogs etc that even make mention of the nomenclature at this time. It's only confirmed that the new models(unnamed) start either mid august or early september for the 1xx series (15x/17x). Clevo doesn't respond directly to emails either it seems, even as a business the information is slightly vague and focuses heavily on what they have currently.

 

Ah yes, sorry, I mixed it up with the P650SX which doesn't have the option for 2*9.5mm

Another question concerning the CPU, is it worth getting the 4790K over the 4790S if no overclocking is going to be done and it will solely be used for games?
Some reviews on notebookcheck reveal that the 4790S runs a bit cooler than the 4790K. Could it also be a bit more power efficient?
Adding the 4790K is like a 50 euro premium but it's 50 € above my budget so I'm wondering whether it's worth it or not

 

To undervolt, yes.

 

Do we have any additional information about this at all. As what form factor it will support or CPU type (desktop/laptop or soldered or not)?

 

Officially, not a word.

 

Officially is a word.

 

Thank you! I've just learned a new word(s) - lol

I looked back at my sources. The oldest sources (last summer) placed Broadwell-E out about Q3 2015, as tradition had it for the past 3 iterations of Intel core series (SB-HW). In Octobe to December of 2014, I found a couple unreliable sources mentioning Q1 2016. Considering Skylake-E, by all accounts to date, will be on time 2016, the idea that all socket 2011 v4 shall be released by Q1 of 2016, if not H2 of 2015, is not unreasonable. I'm saying if them making a P570WM replacement is true (as was speculated in this thread), I would personally wish it to be socket 2011v5 because then it would support Skylake-E and Cannonlake-E (see Intel's tick-tock and agreement with server groups, MB manufacturers, etc. that the Xeon E5 and above will utilize the same socket for two generations of processors). Since the replacement is not being considered until now and may use X99 chipset (Haswell-E/P, Broadwell-E/P (which includes the Xeon E5v3-4)), it suggests only current generation support AND that Clevo will more than likely push off the creation of a Skylake-E/P/Cannonlake-E/P variant when the chips are likely available Q3 2016 (once again on historical trends with Broadwell chocked up to as a variation from the standard).

Edit: I do apologize, but with the current delays of Broadwell, I did not find anything in the past month to confirm or deny the release timeline. Hence, it is speculation, but based on trends. Time will tell and Intel is playing release dates closer to the chest at the moment.

 

Np, always glad to help, context can be a big issue on tech forums where people attempt to maintain accurate information vs spreading rumors! <3 Also bonus seems you learned 2 words! Amazing! This forum just helps in all sorts of ways! Gosh today is turning into a great one!

 

The 4790K is approx. 10 % faster (up to 4,4 GHz@1Core), thats why the "S" (up to 4 GHz@1Core) runs cooler. If this is (and the additional possibility to overclock) is worth the additional 50 $ depends on you. According to what i heard here, you should not expect more than 4,4 GHz @ 4 Cores.

PS: If the 4790K is out of your budget, i'd recommend the 4690K instead of the 4790S.

 

*

Unfortunately, the reseller I want to buy through doesn't offer the 4690K. Only the 4690S...

 

It's Schenker, isn't it? Acc. to what i heard they inofficially do. Just email them.

 

Yes you're right, it is indeed Schenker. I'll email them, however, what are the added benefits of the 4690K vs the 4790S? I understand the 4690 is an i5 and that kinda puts me off..

 

Do you know the differences between Desktop i5/i7? It is only HT and cache size. Additionally there is Devils Canyon.

Disadvantages, in short:
i5-4690K - less cache (6 vs. 8 mb), no HT
i7 4790S - less TDP, no OC, inferior heat transfer (due to being "haswell", not "devils canyon")

If you really don't want to OC, the i7S might be faster, but i dont see an issue with slight OC. If the hardware can handle an 4790K, it can easily handle an undervolted 4690K with slight OC.

 

Xeon E3 v3 or v4 is also worth considering. Search this thread (or the P750ZM thread) for me and Xeon E3 or something along those lines. I discuss the price breakdown of them and they have a different built in tdp for AVX2 instruction set. It will give you professional performance and no throttle on the chip.

 

It depends what you do with it and how the programs you use react to HT.

 

Definitely agree with this. Xeon should be considered because no wasted die on igpu. Definitely recommend the K's though just to undeevolt if you have any interest in tweaking or pulling more performance.

 

Some Xeons have an iGPU.

 

Actually didn't know, but suggesting get a Xeon without one.

 

Xeons E3 v3 which end with 5 or 6 has iGPU, ones which end with 0 or 1 are without.

Though I never was able to confirm that its not the same crystal, just with microcode-disabled iGPU.
I always had sneaky suspicions that for E3 they all come from same Haswell crystal, just binned if, say, iGPU is defective - they disable it and mark it as Xeon E3 v3 by appropriate microcode, setting TDP and freq limits appropriately

http://cpuboss.com/cpus/Intel-Xeon-E3-1281V3-vs-Intel-Core-i7-4790K

Reasons for Xeon E3? Not much...

 

I thought xeon's were binned by their 24/7 robustfulness because of their server nature.

 

Well, Intel can say this in ads, but how to prove it really?
In reality, nowadays you can expect any CPU to be 24/7 robust, because no way to ensure that it will fault only when you exceed certain number of hours per day

 

I bought the -S version of this with M2 500gb drive in it. I ASSUME I don't need any special drivers on my Win 8.1 install USB Drive to install to the M2 slot? I have all the drivers downloaded and on my NAS, and will put them on a USB drive for easy access, but if I need to have drivers to install to the M2 SSD, I'm not prepped for that. I can't find anywhere on the net that says we DO...but wanted to make sure.

It gets here tomorrow! I've already prepped my old Asus to sell to the guy who is buying it, and am a bit anxious to get my new Bat-Monster!

 

Cleaned off the ClU this morning and surprisingly it cleaned off really easy. Of course you must be extremely careful as I saw it could be very easy for a small bead to sink below the protective black layer around the GPU. Nonetheless I applied PK-3 this time and compared to my previous temps they have dropped about 1 degree at most. I haven't checked the paste job to see if this is as good as I can get but PK-3 appears to be ever so slightly better than gelid GC Extreme. I recommended that as the paste to use for the batman since CLU didn't work (at least for my computer).

 

Thanks for testing it. I suspected PK-3 should be better since it better thermal conductivity than gelid, and I planned to use it whenever I decide to re-paste.
Its surprising that despite obvious better specs PK-3 is nowhere as known/popular.

 

I'll try to have preliminary numbers by Monday. Also, 1mm pads on the back of the video card. Those will arrive by Friday or Saturday. Today, my 3m polishing paper shall arrive with the liquid electrical tape. I will delid, verify I didn't kill the chip, lap to flat (my chip is quite concave in the center), then polish to under a micron grit, polish heatsink, then adjust height permanently of the mount. I'm debating using the electrical tape backlight bleed fix while it is all apart. I don't have bad bleed, just try to fix what is noticeable. Reassemble. Never open again (except for routine cleaning)!!!

That's because in common roundups it is about half a degree to a degree hotter than gelid. It is still well regarded though. What is a shame, only skinneelabs and Tom's hardware have tested with different mounting pressures. But, with so many holding it as less capable in test situations, it will be relegated. Also, the W/mK on TIMs is misleading. Mx-4 has a rating of 8W/mK. Look at its tested performance. So there is more variables here than just that. But pk-3 is consistently in the top grouping!

 

Nothing is misleading about better conductivity (assuming you understand what it means and that there can be other factors in play which you missing). E.g. paste could have better conductivity but worse contact performance (due to particle shape/sizes).

 

True, but some independent testing had found many overstate conductivity, . Even if by small amounts. Aside from that, you are absolutely correct. But most rate it in between two flat surfaces. Many cpus have concave parts. Also, there can be different mounting pressures and potential gaps between the heatsink and ihs that are equal to or greater than 0.1mm. After all this and more is factored, then winners and losers can be picked. I use these factors to base my mods on to reduce or eliminate surface mating issues, which is the largest problem plaguing heat transfer (followed by thermal resistance once mating or proper gap filling is resolved). The heat transfer is only one part of the mating...

Edit-not my best explanation. Waking up. But hopefully my point isn't lost...

 

Although Pk-3 is slightly better on my setup it is pretty thick. I had to soak it in warm water before I used it. Gelid GC Extreme is more beginner friendly and basically the same temps. I haven't read of any break in period for PK-3 so I'm assuming it's as good as it will get. Also @ajc9988 please make sure to take pictures and document what all you purchased. I'm considering following your steps if the results are what we expect but if it only results in a couple degrees I may just not bother.
