Hi guys, today I received my 2570p from ebay. Looking forward to modding it tomorrow, starting by replacing the CPU with an i7-3720QM. Also ordered some copper shims from ebay so I will try out the cooling mod that nando posted.

However, the laptop that I purchased came with a 180GB SSD so I now realize I might need more storage. I was thinking about replacing the optical drive with an HDD in a caddy. Could someone with experience doing this check the parts that I will be ordering to see if they are compatible with the 2570p?

The HDD Caddy I'm looking at is:

SATA 2nd Hard Drive HDD Caddy Bay for HP EliteBook 2570P 2560p 2530p GU40N GU60N | eBay

(only $12 so cheaper than the newmodeus caddy posted in the OP)

And the HDD is here:

HGST Travelstar 7K1000 HTS721010A9E630(0J22423) 1TB 7200 RPM 32MB Cache SATA 6.0Gb/s 2.5" Internal Notebook Hard Drive (Standard model) - Newegg.com

I know it has to be 2.5'' 9.5mm but just want to make sure I didn't miss anything.

Thanks in advance!

I actually have made a SATA caddy with a genuine 2570p faceplate that I'm now selling. If you're interested of this just send a PM!

Edit: 90% of caddys described to fit our system does not. Look at the faceplate of the item you linked for instance and compare it to yours. It's flat and will not fit.

So today I replaced the CPU of my 2570p with an i7-3720QM processor, with a 25x25x1mm copper shim between the CPU and the heatsink. However when I put my computer back together and tried booting it I got a weird error. When I try to boot, the laptop makes some noises but all I see is a black screen while the caps lock and the num lock LEDs link three times. Then the fan starts spinning loudly but the computer still won't boot. Has anyone encountered a similar problem when they replaced their CPU?

It was working perfectly fine before I replaced the CPU, did I just mess up the installation process somehow?

Yes, I tried doing a 'hard reset' as was suggested by google. Kind of at a loss right now, I put back the original processor and I'm still getting the same problem. Going to give HP support a call today and see what they say, if worse comes to worse it's still on warranty!

Edit: Strange, left the original processor in overnight and when I tried booting it now it worked fine. Maybe it just takes a while for the mobo to get used to the new CPU. I'll try putting in my 3720qm now and leaving it in overnight.

Nope, leaving the 3720qm in overnight did not seem to work this time. I'm starting to worry I bought a defective processor since no one else seems to have gotten this problem. Anyways, the plan is to call HP support today and see what they say, and then I'll decide whether I want to return the 3720qm. If anyone has suggestions for things to try let me know.

Edit: HP support was not very helpful, I am just going to try buying a new processor as see if that works.

Ah, so replacing the CPU should ideally be fairly simple, i.e. you can simply swap out the CPU and boot up right away? I read on the HP support forums that sometimes it is necessary to reflow the solder for the CPU socket first in order to get it to work since the sockets have a tendency to fracture over time... In any case, I put back the original processor a few hours ago and it's still refusing to boot. Which suggests that it's probably a problem with the motherboard to be honest, am considering sending it in for HP to repair since it is still on warranty.

Quite strange that nobody on this thread has encountered this problem before, since a google search showed that several people with HP notebooks had similar problems. Hopefully my experience can help future generations :P

@hatoblue, have you tried booting with one RAM stick installed? Try alternating RAM configurations too, so boot with one slot empty, then switch slots, then switch RAM. A BIOS reset by unplugging the BIOS battery could be helpful too.

Usually when I open a computer like that I clean the RAM contacts with a Q-tip and isopropyl alcohol. If none of those work, you're probably right in that you have a bad CPU. I tried upgrading the CPU in my old Acer 1810TZ by sending it off to a company to get the BGA CPU replaced and ended up with the same result that you had. Good luck!

If anyone is thinking of using one of the previously discussed modified BGA CPUs, I would be concerned with clearance issues. In order to make the BGA Ivy Bridge chips work, you'll need an interposer (adapter) to convert from BGA1224 to rPGA988B (socket G2). I would guess that it would effectively double your CPU height as well. For a pic, check here:

https://www.mill-max.com/new_products/detail/6

I also thought that the advantages of BGA were that it was soldered to the board which reduced the height of the setup as well as provided an additional 1224 points of contact for heat dissipation. IIRC, BGA chips flow heat much better to the motherboard than socketed solutions, which can help lower CPU temperatures. The pins in rPGA setups are like a stack needles trying to transfer heat from the CPU to the socket and then to the motherboard, vs soldered pads. I would consider using the BGA+adapter chip in a desktop setup, but I would be surprised if it fit in a laptop.

@phillofoc

On the 2570p I'd say you have about 3mm clearance between back cover and heatsink.

Any idea of the height of that adapter?

I imagine that the clearance would be close enough where I would worry about the screws not biting and being able to get the heatsink mounted to the board. It all depends on the height of the interposer, but I would imagine that it would be at least the height of a mobile IVB CPU without the pins (so the actual silicon plus the green part). Here's an ebay image that I stole, with an appropriate link:

post-8761-14494997883841_thumb.jpg

Intel Core i3 3217U SR0N9 BGA to PGA Laptop CPU 1 8GHz 3MB Socket G2 988pin | eBay

The dark green part appears to be the BGA cpu, and the light green part the PGA interposer. I wouldn't try it in my 2570p, but would consider it if I had a SFF PC that used mobile chips. There's a few mobos out there that do. Now, if there was a 3840QM for super cheap, or if I really wanted a feature in a BGA CPU that wasn't available on the PGA (eg the 3632QM) then maybe.

Hi guys,

I just wanted to ask a few things again.

1.) Are our Extremebooks compatible with the newer Hybrid drives like SSHDs or the Dual Drive of WD?

Seems like having larger storage with SSD-like speed for the OS can go cheaper if I go with a Dual Drive rather than a pure 1Tb SSD.

2.) Does our BIOS restrict the max capacity of HDDs? Or, in the event that larger HDDs are available, can we exceed the 2Tb HDDs available today?

I'm also thinking of getting a 2Tb WD Green in the caddy if that is compatible.

What do you guys think?

I've had a Momentus XT SSHD plugged into the 2570P. No problem. They certainly do boot faster than a standard HDD. Only thing that I didn't like is that it appeared to consume higher amounts of power, pretty much the same as a SSD + HDD. If that's a concern then I'd advise getting a SSD and a separate HDD in a caddy.

Only restriction that I'm aware of with the 2570P is the drives must be a 2.5" 9.5mm tall one. Larger capacities are available in the 12.7mm form factor which definitely will not fit. The largest capacity 2.5" 9.5mm drive available today in that size is 2TB: Samsung Spinpoint M9T Hard Drive Review | StorageReview.com - Storage Reviews

Thanks for the feedback Tech Inferno Fan! I didn't look closely at the thickness of the drives. So 9.5mm it is..

As for the WD Dual Drive, power consumption is rated at 0.9W (idle/standby) / 1.9W (read/write) and hardware is available for about $200+ online.

Don't your SSD (0.4W) and HDD (0.8W) total at 1.2W idle? This might be a cheaper and better solution with space for an ODD still.

Oh, how I wish though that the DEVSLP feature on the new Samsung 850 pro was supported by Ivy Bridge. Would've thought about getting that too.

I was running a Seagate Momentus XT Gen3. They are considerably cheaper than the WD Dual Drive, though only have a 8GB SSD cache. Available in up to 1TB size.

Your third option would be a mSATA retrofit. Nobody has been successful so far in doing. Involved would be soldering those unbridges SATA tracks on the WWAN slot (pin 23,25,31,33), then cross flashing a mSATA-enabling bios like a 8470W one. The bios flash being the risky part of the process. It may brick the system so an emergency recovery strategy should be in place in the form of a preprogrammed bios chip you'd solder on or another systemboard.

Hello everyone.

I recently installed an i7-3820QM. Today i ran Throttlestop and it wouldn't go above x31 (from the start) even though i set the multiplier to the maximum X37. Why is that?

paperclip and jacobsson's i7-3820QM OEM and QS versions both ran at x34 here. Pls ensure you have the Intel HD4000 driver installed and set the power profile for it to 'maximum battery'. In that way you reserve maximum package TDP for the CPU rather than iGPU.

If after that you are still getting only x31, then please check the 'log file' option prior to doing the TS-bench. Once you see performance pull back to x31, stop Throttlestop, exit and upload the long from the Throttlestop\logs directory to say mediafire.com. I'll review it to see if you are being TDP or temperature throttled. If it's the latter then improving cooling can help http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-45.html#post80894 . If the former then you happen to have a poorly binned CPU with the only solution being to replace it with a better one.

I have the HD4000 installed. By 'maximum battery' you mean 'power saver'? I'm also connected to a docking station and didn't think that could make a difference but actually it covers the vents a bit. It doesn't pull back to x31, it moves up in the first 10 seconds of the run and than settles at x31. Here's the link to the log file of the two runs i did.

I mean in the Intel Control Panel->Power change the AC and battery profile to 'Maximum Battery Life'.

From your logs it's clear that temperature isn't an issue. Instead, you are being TDP throttled back to x31. Looks to briefly almost hit x32.

Is this a OEM or ES/QS chip? I'd expect the latter to perhaps be of lower quality but OEM chips tend to do OK. A i7-3820QM has a x35 4-core max multi, same as a i7-3740QM, so if it can only hit x31 then it's a poor chip. In fact, we see a i7-3630QM doing better here, hitting x32. Even the lowest tier i7-3610QM has been recorded at x31 4C TS-bench test in that link.

Thanks for the info. Changing the power settings don't make a difference. I don't know which version it is, how can i check this? It's been taken out from a lenovo laptop so would that make it OEM?

If it came out of a Lenovo machine then you'd expect it to be an OEM CPU. The way to know what it is is to read the SSPEC off the CPU itself. "SR0MK" is a common i7-3820QM OEM SSPEC. Alternatively, run hwinfo and read the SSPEC parameter, eg below:
