    Hey guys,

    I wanted to bring back the PSU/charger topic back a bit :) Have some of you 2570p veterans had experience with a 65W power supply?

    The thing is, I switched from 90W to a 65W about a month ago, since the 65W piece weighs some 100+ grams less.

     

    So far the charger doesn't get *that* warm even at full load, and I didn't notice any drop in performance (running a Core-i7 3720QM at 3400Mhz, 2x240GB SSDs in RAID-0, Linux Mint).

    Am I missing something? Only thing that I am not using a battery at all, is that what makes the whole thing possible?

    I've been using a 65W PSU since 2014, - no issues so far. I run both Linux and Windows.

  2. There's a lot you can upgrade in this machine. CPU, RAM, SSD. Keep in mind that quad core processors will require a cooling upgrade. A good thermal paste is not going to be enough. Check the owners thread for details. But for a time being you could set max CPU power to 99% in the power settings, that disables turbo boost. 

  3. Hi Guys,

     

    It's good to see this thread still alive and kicking! What's more, some passionate people are still looking for more mods, upgrades and improvements! 

     

    4 years later, my machine is still my main workhorse, no regrets, no failures!

     

    Would like to chime in with regards to cooling mods. 

     

    @Batyanko and Shikyo, - good job guys! Few years ago I did some modding of my own, then reached out to a couple thermal engineers for insights. Potentially, we could tame a 3x40QM by adding another pipe to the heatsink. The fan is pretty strong at max RPM and wouldn't be a major bottleneck in this case. Two pipes wouldn't double the termal dissipation envelope, of course, but we would gain about 10-15W IF we can successfully get it out of the system. The radiator/grills is the main issue here. Which can be somewhat mitigated by adding layers of PGS - Pyrolytic Graphite Sheet, It can also be slapped on the pipes and heatsink. Pipes can be ordered from enertron and PGS from digikey.

    We can also slightly improve the air circulation inside the system by drilling small holes in the back plate. I think the cooling can be improved sufficiently to keep a 3x40QM under 85c running at max clocks 24/7. Right now, for reference, my heatsink (single pipe) can only manage about 30-32w with stock fan control and about 35-37w at max RPM. 

     

    Game on!

  4. Looks like the mode I was using in tpfancontrol is not 100% lol. It's the "insanity" mode, or "damaging". The thing is, I switched over to linux and the temps are too high at times, so Im looking into ways of managing the fan. Appreciate any insights on the matter.

    Edit : Just read this post again and it doesn't make any sense lol. Missing too many hours of sleep.... So, to clarify, NBFC has a linux version which uses the same profiles as under windows, so I was hoping to make it work. I was especially interested to get the same fan speed as with tpfancontrol - which is the "damaging" or hairdryer mode. But it looks like I can't get it to work at all under linux mint 17.2.

  5. Notebook FanControl - an alternative to TPFancontrol for the 2570P

    Found another fan control utility for our 2570P with a nicer configuration interface than TPFancontrol. The software is called Notebook FanControl and is available as a free download at: [Vorstellung] NoteBook FanControl (NBFC) - ComputerBase Forum. Can set 2.5% (2825 rpm)-100% (5120 rpm) manual fan control or temperature-based rules. Nice. Though because there isn't a 2570P configuration item I use a HP 8560P or ZBook 15 instead.

    Hey M8, long time no seen! How's life? Looks like I've missed out on a lot of action here....

    Sorry for the necro here but did you actually manage to run the fan at 5k rpm using this program? if yes, what settings did you use? I tried loading both 8560p and zbook 15 but both are not doing true 100%. It's showing 100% inside the program but the fan runs at about 3k rpm. Looking at the xml config files Im not seeing any settings with RPM, only percentage % of the fan speed on a scale 0 to 255. I guess it's reading the registers somehow but those readings are clearly incorrect. Am I missing something here?

  6. Long time no hear! Welcome back. I've had some personal PM with jacobsson about the i7-3840QM and how efficient it is. Unfortunately we have no tabular data for a OEM version of it at http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-37.html#post77432 . Would you mind submitting the TDP vs multiplier data for your CPU so we have it on file? If OK to do that, please run with the iGPU control panel set to 'maximum battery life' to dedicate maximum package TDP for CPU use.

    Yeah, it's been a while.Too busy with work and other stuff. How are things around here? Any new exciting developments? Has anyone managed to run 1866mhz+ 16gb RAM yet? Last time I checked it was still capped at 1600...

    Will submit the data when I have a moment. I'm finally going for eGPU this Xmas!

  7. i7-3840QM is x36 capable during the Throttlemark TS-bench 4-core/8-thread test, but only if the TDP is extended. As the 2570P locks the TDP to 45W it means the full CPU capability is never realized. We can see this when evaluating the results at http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post95181 . It means then that the best value for money CPUs to get are i7-3630QM, i7-3720QM, i7-3740QM/i7-3820QM. No point in paying a premium for a i7-3840QM if it's going to perform at i7-3740QM/i7-3820QM levels or worse still.
    @Tech Inferno Fan

    This for me is an eye opener, a shocker even! I was planning to purchase an amazing 2570p and pop in that i7 3840qm right in! Heck I want to even risk it and see if it would run in my Lenovo G500 which features a removable cpu slot, any Idea if this would be possible in my setup Tech Inferno Fan or it needs to be supported by the BIOS?

    (i7-3840QM vs my mobo which can only handle 35W CPUs) Otherwise, highest spec compatible with my laptop is only an i7 3632QM...sorry for being off topic

    I wouldn't say the 3840QM is a bad choice. Mine is able to maintain stock speeds minus ~100-200mhz and up to 4Ghz on a single core with OC. But that's when running on IGP and I bet it would go full gas on eGPU (will test). But the part that I like the most is that it runs ICE COLD! when locked down to 3632QM frequencies. I had both CPUs and the 3840QM wins hands down in every respect. As for 3820QM/37x0QM I saw those dropping 100-200mhz too when fully loaded on IGP, so dunno if they are more efficient.

  8. @jacobsson,

    Good stuff, Bro! Keep at it, I might be able to join you soon (currently too busy with work and D3 lolz). Keep in mind that you will need to completely disassemble the machine to mount the new HS. If everything is done correctly, the radiator will become your new bottleneck and I don't really know how we can improve that. I thought about using a thin copper wire and wrap it around the bottom pipe a gazzilion of times but that would only slow heat buildup and we need something to take it away from the system. Ideally, we would need a complete redesign of the HS, replacing the pipe with a 8mm and less flattened one. maybe adding more fins on the radiator's side. Then we would see a serious improvement.

  9. so is there any sense to putting 45W TDP CPU in 2570p?

    U can run it at the 35W performance level and have far better temps than with a 35W quad. You could also run it at the performance level of a 35W dual core and have even better temps. That alone is big pro in my book.

    Other than that it's about bragging rights mostly and potentially making your system a bit more future proof. In everyday life and even gaming, I don't notice any difference between a 3632QM and 3840QM. But I do a ton of virtualizaiton and there those extra clocks shine. I was hitting 70% utilization on a 3632QM when running my virtual environment. Now it's like 35-40% tops.

  10. See there's been some progress here! A couple of things:

    The CPU is definitely limited at about 35W, hence all high end quads show reduced clocks. Your processors are not faulty, just locked at reduced clocks by 100-200mhz. The good thing is you still benefit from the relatively high clocks, extra threads and cache.

    Also, the reason there's a temp drop when putting a cooper shim between the cpu and the hs is because of the increased pressure. You could also put thin washers on the HS screws and get better results without using any shims, the fewer layers you have between the cpu and pipes - the better are your temps. I was gonna do that but my current mod is adequate to control the temps as is, even at 30c room temp. But if you are aiming at the perfection:

    1)put washers on the hs screws to increase the pressure between the cpu and HS.

    2)glue extra copper on top of the hs. (if you can mod an extra pipe in such a way that it would get enough surface contact with the radiator, would be legenDARY!!)

    3)drill holes in the back cover to improve air circulation.

    4)* If you don't mind the noise, max out the fan whenever benching or gaming.

  11. 2570P performance-enhancement questions for HP

    Hi everyone, I've prepared my list of 2570P performance-enhancement questions in the spoiler below. These are to be presented to Ajay, the senior HP notebook engineer. Feel free to peruse and advise if there are any others you may have that could be added on too.

    Hi Ajay,

    Below I re-submit the questions I have for the 2570P engineers with the extra additions. There is no 12.5" 2570P Haswell successor, such as a ZBook 12, planned even after several attempts to request for one from Dion Weisler and Enrique Lores (notebook managers). Nor is there any planes to produce a systemboard that would allow 2570P owners to upgrade to Haswell internals.

    Hence why the aim is really to maximize performance of the 2570P to workstation levels. Answers to the questions below would help with some of the discussion happening at 12.5" HP Elitebook 2570P Owner's Lounge . Consider too 2570P designers are welcome to post their own personal research there that may help the discussion. I realize some answers of the intended modifications be best discussed outside of HP.

    My contact details are xxx available during business hours GMT+10 (East coast Australia). Though you may find it easier to simply answer my questions via email.

    Technical details requested about the 2570P

    Physical hardware modifications/upgrades

    1. WWAN slot extra lines: If the 2570P systemboard factory unbridged tracks in the WWAN slot are bridged (pin 23,25,31,33), does it give a mSATA or mPCIe electrical link? If it's mSATA, does the BIOS make provision upon detecting it to enable the corresponding port? If it's mPCIe what port number is it? Based on the 2560P schematic I'm guessing it's a mPCIe port1. Someone with a 2570P schematic could answer that question.

    2. Better heatsink: is there factory 2560P/2570P heatsink part that incorporates a second heatpipe for improved heat transfer? This would alleviate the need for heatsink mods, examples by Aikimox, bjorm & jacobsson's 'Anarchist' to reduce fan activity or host a 45W i7-quad comfortably.

    3. Backlit keyboard retrofit: is there anything in the HP part catalog that would fit the 2570P chassis perfectly, with adequate length ribbon cable. I realize that would require 5V or 3.3V to be patched to the backlight connector. The '820 G1' keyboard looks like it might be suitable. REF: Tech Inferno Fan

    4. LCD panel upgrades. We've had no success fitting the Lenovo X220/X230 IPS panel with wide viewing angles due to physical clearance issues. Is there any other wide-viewing angle panel that would fit in within the LCD bezel? Reference: bjorm and pandaleo

    Or better yet any higher resolution panels (eg: Dell XPS 12.5" 1920x1080 LCD?). Higher resolution panels require a dual-channel LVDS electrical link which someone would need to confirm. Could someone review the schematic to advise? The 2560P had only single-channel LVDS good for 1366x768 but not higher so it's likely the 2570P is the same. REF: Tech Inferno Fan

    BIOS enhancements

    1. Fan noise: can the fan RPM cut-in frequency be lowered from 3200rpm? It was necessary to do quiet_fan: 2x1N4004 diode mod (bjorm) & : as a workaround to reduce fan RPMs including cut-in RPMs

    2. Increasing CPU power limits: can a BIOS be made to set a higher 45W (or completely unlocked) CPU power limits such that a user installed 45W i7-quad can be used at it's full performance? Currently the power limits are set to 35W which decreases the turbo max multiplier by 2 (200Mhz).

    Some users are contemplating flashing a 8470/8570 bios with factory 45W i7-quad support and mSATA support to unlock these performance features. RSA bios protection making user modifications to the factory 2570P BIOS impossible.

    If they did flash either of those bios, would it cause the system to hang?

    3. Removing WWAN/bluetooth whitelist: we've found that the wifi whitelisting appears to be disabled. Can the same be done for the WWAN and bluetooth whitelists in an updated BIOS ?

    4. Enabling ASPMs for better battery life: can INFO: 33% longer 2570P battery life by enabling ASPMs and L0s L1 using software be added as a BIOS option in an updated BIOS revision? Contrary to my initial findings, there is no negative side-effect with the SD/MMC controller. Insertion of a SD card into the reader sees it re-appear in Device Manager.

    Great effort, M8! Alas, we all know the answer. If HP honors you with a reply, it will probably be somewhere in the "not tested, not supported, not designed, no..." ballpark :(

    I'd be surprised if the was a constructive and positive feedback from them (or any other vendor for that matter). Still, crossing fingers and toes wherever possible. Good luck! :)

  12. Now, when you say bang for buck do you mean the performance? If so, Clevo and their resellers (some mentioned here) would be the best option. The thing is, when it comes to high-end laptops, there's more to it than just power. What about durability and long term reliability? How good is support? Can I overclock the components and will the cooling system handle it at full load? What about the extra features, ports, upgradebility options?

    If you try and look for answers to the above questions, you may find that Clevo's aren't always the best choice though I agree, price/performance ratio is their top selling point. Personally, I'd look into something that will last and handle everything I might wanna throw at it.
