  1. Your benchmarks where interesting, but I observed the same lowering in battery life when I switched from dual core to quad core. I don't have my dual core anymore, to test again. I think that in your benchmarks the problem comes in full load, indeed, the dual core will be at full load of 2.4 Ghz (let's say), but the quad-core will also be at 2.4 Ghz in full load in Windows. When I say full load, I talk about medium load also (it is scarce to use a laptop in 100% idle, watching a film can be considered as idle but browsing Internet on the greddy Chrome, not very much). I would be interested to see the benchmark of system consumption with 2.4 Ghz (lets say) for the dual-core and quad-core. For sure it will be 2x more CPU consumption for the quad-core. Nevertheless, the quad-core should perform 2 times quicker than the dual-core, thus finishing the task 2 times earlier, but I doubt that Windows CPU governor is efficient to the point that it would turn off the corres as quickly as they stopped working. This would explain why I had this feeling also of the battery draining far more quickly on quad core than dual core, because in medium or full load, all the cores turns on (consuming 2x more power), and they don't turn off as quickly as they turn on. Edit : I was that you are on Linux Mint, maybe the governor is tweaked. But the reasoning on Windows (and thus, the consumption at 2.4 Ghz lets say, and full cores meaning 2c/4t for the dual core and consumption at 2.4 Ghz at 4c/8t should be still valid)
  2. I would recommend you to go for the best. You have 16 Gb of RAM, so you need power. I have a 3820QM and I sometimes throttle but even with the throttle I have better benchmarks than 3610QM or dual core CPU (tested). If I could buy a 3940XM I would have done this. Contrary to what the first post says, in Windows any quad-core can be software limited to two-cores or one core, so if you need battery well this can easily be done in Windows. I will idle with this configuration dual-core mode on quad-core with 0.5W more than a real dual-core (tested between my original i5 35xxM and the i7 3820QM I have). This is negligeable towards all the speed advantages of the quad-core. All depends to you, do you want quad-core with negligable battery hit (I would not say 1 hour, more like 20-30 minutes with easily tweaking Windows, but this is nothing, if you need battery just buy a newer laptop), or do you want speed and a real work-station you can plug on an external monitor and have desktop like performance. Thus, this is less and less true with the latest Intel i7 10-gen processors, even i5 and AMD, caping at more than 4 Ghz.
  3. The three big limiting factors of the 2570p according to me : 1/ Noisy with quad core CPU 2/ Screen colors are bad 3/ WebCam quality So, yes, I agree with you.
  4. Yes it is really impressive, I was wishing for high quality mods as we can see on the Lenovo thinkpads Are you sure it is the 2570p ? Me I don't like PWM but I never had problems with screen flicker with the 2570p The low quality screen according to the very low grade color calibration was the main issue, all the time I used the 2570p
  5. Would be pretty interesting to have a 2k screen, because with the 2570p + 3820qm and the low-res 768p screen I often feel like the power is not fully used.
  6. Yes but no, there is no need to have a free cady for the sake of having a free cady. First you gain only few grams if it is a weight problem so this is pointless. The only useful thing with the mSATA is either RAID0+1, for high resilience, but a laptop with high resilience if pointless, or either having a 2TB hard drive and a high performance (800 to 1000 mb/s) RAID0 drive of SATA, this could be interesting. But you have still not told us about this question, is your drive in the WiFi slot or on the WWAN slot ? If you have 16Gb RAM, I recommend you to download the very old and known software "PrimoCache" it is a software to increase the cache of the SSDs (or HDDs) in using free RAM on the machine, so I have "RAM-like" speeds when loading some files (8 Gb/s for sequential read see benchs below). ----------------------------------------------------------------------- CrystalDiskMark 6.0.2 x64 (C) 2007-2018 hiyohiyo Crystal Dew World : https://crystalmark.info/ ----------------------------------------------------------------------- * MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s] * KB = 1000 bytes, KiB = 1024 bytes Sequential Read (Q= 32,T= 1) : 8450.388 MB/s Sequential Write (Q= 32,T= 1) : 6711.163 MB/s Random Read 4KiB (Q= 8,T= 8) : 1464.376 MB/s [ 357513.7 IOPS] Random Write 4KiB (Q= 8,T= 8) : 1273.470 MB/s [ 310905.8 IOPS] Random Read 4KiB (Q= 32,T= 1) : 412.207 MB/s [ 100636.5 IOPS] Random Write 4KiB (Q= 32,T= 1) : 471.074 MB/s [ 115008.3 IOPS] Random Read 4KiB (Q= 1,T= 1) : 444.689 MB/s [ 108566.7 IOPS] Random Write 4KiB (Q= 1,T= 1) : 413.750 MB/s [ 101013.2 IOPS] Test : 100 MiB [C: 60.9% (72.2/118.6 GiB)] (x1) [Interval=5 sec] Date : 2019/09/27 20:25:04 OS : Windows Server 2016 [10.0 Build 14393] (x64) PS : I have a mSATA drive on a standard SATA adapter in my 2570p so I could do the same screenshot as you without the BIOS mod ^^
  7. If the mSATA replaces the 3G card well this can be more interesting. But if it replaces the WiFi card, the problem with mSATA on the 2570p is that there is one port already occuped by this important WiFi card so not possible. Anyway, I really hardly see myself spending money on an mSATA because the last time I searched 6 months ago, as mSATA is a "niche" card, it was more expensive than a standard big sized SATA drive so I could have a big size SATA drive with more storage than buying a small SATA drive + mSATA. But, one question, can you do a software RAID with mSATA and SATA ? If it is the case, this can become pretty much interesting, but we have to bare in mind that the CD drive on the 2570p can be replaced to have a second SATA drive, so maybe we could do some RAID0+1 or somthing like this. Anyway, thank you for this very interesting mod that we have been waiting since years... =b
  8. Pretty, I would like to help but don't know any thing about modding UEFI firmwares. Thus, I am not sure there is need to put efforts into enabling mSATA cards, this technology is pretty much dead. I will prefer invest bucks into a standard SATA drive that I can easily connect in another computer than a mSATA. Nevertheless, the no whitelist is very sweet and good. Thank you.
  9. I recall that even with a 45W quad, the CPU is BIOS-power limited to something like 40W for the 45W quad (not 45W). Benchmark showed that the lask 5W is mainly for the integrated GPU in the 45W quad. So any 45W CPU will run at fullspeed if you don't use the GPU, and at least if the cooling system is OK (or the 2570p case is cold, I observed that the case slows down the CPU building temperature pretty much a lot). I doubt that you have a CPU problem, this is very very rare, but it could happen. Same for the mobo, but it could be. I think it must be the battery
  10. I have a 2570p with 45W quad and 65W charger, and *when the battery is fully charged* I can easily run any 3DMark or heavy Excel sheets, 100 Google Chrome tabs or video conversion. No problem. The laptop simply throttles but because of heat (100°C for the CPU in ThrottleStop). I don't know where you read that 45W quad and 65W makes the 2570p crash but this is bullshit. My laptop throttles only because of heat, not because of the charger. When it is "cold" for example after sleep then wake, the CPU runs at full multiplier until the temps reach 100°C.
  11. Yes it is either your laptops specific battery because I have a 45w CPU running fine on battery, but with degraded performance, this leads me to my second point : Or either, it is because you try to run the CPU at full speed when on battery, because not any laptop of this grade of CPU even in 2019 will run at full speed (as if it is plugged in) without having sudden shutdown issues.
  12. I have already thought about this. Well, the best of the best laptop, is Thinkpads, just read this article to know why : http://www.cnmod.cn/2019/06/05/51nbs-x210-review-a-faithful-recreation/ Basically, the X201 of 2010 (or some year not to far) is so popular that chinese dude made an all new motherboard with an intel core i5/i7 8th gen (low power quad core versions). DDR4 and 32GB ram. 4k monitor compatible. Insane. I wonder if there is also a mod for i9 or i7 hexa core. The CPUs are soldered, but those CPU mods it is pretty close to what we did with the 2560p/2570p mods.
  13. Only security update ENHANCEMENTS:- Enhancement to address security vulnerabilities CVE-2018-12126, CVE-2018-12127, CVE-2018-12130. In 2019, I am pretty sure you can lost hope that HP add any new feature to the 2570p, we are even happy that they still update the BIOS for security... The advantage in having a entreprise grade laptop.
  14. I would like to upgrade from a 3820qm to a 3940xm. Who can do a throttlestop or hyperpi benchmark so I can compare how much few % I will gain ? It will NOT be a lot but I plan to upgrade the cooling system with a water pack. I simply want to have the best configuration for the 2570p, with no commenting.
