12.5" HP Elitebook 2570P Owner's Lounge

[phillofoc]

Hi guys,

first a big thank you for compiling so much information about the 2570p neatly here. However, after browsing all pages, googling and using the forum's search, I still don't get which CPU-Socket type to get if I want to do an upgrade. Most of all quad-core upgrades mentioned are available as BGA1244. If memory serves right, the 2570p has a BGA1023 socket. Can you just drop a BGA1244 CPU in a BGA1023 Socket, or does one have to get a PGA988->BGA1023 modded CPU?

Thanks in advance

BuzzDee

You need a rPGA 988B, aka Socket G2, chip. The PGA has the pins (Pin Grid Array) that go into a motherboard socket, while the BGA has solder balls (Ball Grid Array) that gets soldered to the board. One user on here got a BGA chip to work on his computer that was pre-soldered onto a BGA-->PGA adapter to work in his 2570p. Don't get a BGA chip with the hopes of soldering it on an adapter yourself, as you need special equipment to make it work.

Good News! Seems like the new Maxwell GTX880 will draw power just as much as a GTX680!

Follow-up question. How exactly will flashing an 8470p bios be of any improvement to our Extremebook? And why is a spare bios chip needed for standby?

@Tech Inferno Fan, according to the official Intel website, the BCM4352 should be a compatible WiDi adapter even though it is not made by Intel.

Others have posted screenshots complaining of the same problem.

After much speculation, I have come across the WiDi solution. WiDi apparently needs Windows 8.1 Broadcom drivers to work.

Can someone with Windows 8.1 and a BCM4352 confirm if WiDi drivers install? Or can I simply install the Windows 8.1 WiFi drivers over Windows 7 and install WiDi from there?

UPDATE: Can't get WiFi W8.1 adapters to install on W7

Hi Guys,

I am running a i7 3632qm in my 8470p and i'm looking to upgrade it to something like a 3740qm or 3820qm, (I play lots of games and lots of VM's)

But I saw an ES 3720qm chip QBC1 on ebay with 8mb L3 and a 'unlocked multiplier', this looks just like a slightly downclocked 3920xm

With the Intel management engine bypass, will I be able to overclock this cpu by increasing the multi? Or am I better off getting a non unlocked version

(Idle(ish) powerconsumption is a concern for me, I need my laptop for many hours at uni using IDEs)

Thanks for your input

Good find with the BCM4352 WIDI support. Please keep us posted of your findings.

OK. The 8470P/W cross flash to a 2570P would be only provide one possible benefit. That is, if you did bridge the WWAN SATA lines to give an electrical link AND the rest of the 2570P is pretty much a mini 8470P/W, then it would enable an additional SATA port AND provide mSATA cache facility. A backup BIOS chip is recommended if trying this so you can recover if it doesn't work.

The unlocked multiplier, like on a i7-3920XM, requires BIOS support to unlock. Something the HP Elitebooks do not provide. Furthermore, IVB Elitebooks are TDP locked to a max 45W.

I've found that 45W TDP-throttling occurs such that CPUs like a i7-3740QM, i7-3820QM or better often can't even hold their maximum x35 4-core multiplier. Worst one had a -400Mhz (x31 instead of x35) deficit. Therefore there is considerable variation in TDP of individual Ivy Bridge CPUs. The way I was able to get best performance was to test about 4x i7-3740QM CPUs and cherry pick the best one. You can see my testing results at http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post95181 .

The OC ME FW unlocks BCLK overclocking capability, allowing an additional 5% BCLK overclock. There you are stretching the system out to get extra performance from the generous VID/TDP overhead Intel adds for stability across many physical environments.

Damn, thought I was onto something major.

Will be going for the QBRP D0 Stepping model then

Thanks for the advice, you da bomb

Thanks, now I get it. Honestly, I have no need for an additional SATA port yet unless mSATA SSDs are priced much closer to HDDs. But I'd surely love to try it out one day.

Will follow up on the WiDi feature when I finally convince myself to upgrade to W8.1.

I use 2x of this model for my Asus G46VW:

$122 256GB Kingfast mSATA

I'm currently waiting for a mSATA to SATA adapter so I can get some raid 0 going =)

[badbadbad]

That's great buddy. But I already have a Samsung 840 EVO 500Gb SSD (gift) and am planning to pair up another one when I have the budget for it. The third mSATA would really just be for storage so getting max storage for a premium cost is not really appealing to me.

Can you Raid-0 drives with different storage spaces?

I'd recommend getting a 256GB Samsung PM841 or PM851 mSATA for ~US$135-delivered:

These rank highly on performance comparisons: UserBenchmark: SSDs Compared

[jacobsson]

@badbadbad

Is $122 expensive for 256GB? I did not find any cheaper mSATA that seemed respectable.

Afaik it is possible to pair difference sizes of drives, only the combined storage would be 2x the smallest of the drives (same goes for the speed).

[badbadbad]

Actually, I was supposed to go that route and get two cheap SSDs to enjoy Raid-0 and to save up for an eGPU. But since I won a Samsung SSD from a raffle, I was looking to invest in another 500Gb to get a comfortable 1Tb of storage.

Would a cheaper 512Gb SSD be ok to pair up with the Samsung one I have? Or will it be unreliable and have instability issues? I'd be spending as much as you did if I get another 500Gb EVO since it costs about the same as both of your drives.

You want two identical SSDs for optimal RAID-0 performance. In your case, have you considered the following. (1) and (2) would cost about the same, leaving change to get a eGPU.

(1) just running the 500GB EVO standalone? Then you get to keep the second drive bay for use with a HDD or optical drive

(2) selling off the 500GB EVO and getting 2x250 units for RAID-0 . I'm guestimating you could do that without incurring any additional cost. Benefit of RAID-0 being the 2x6Gbps interfaces, giving over 1GB/s sequential transfters.

(3) Getting a second 500GB EVO SSD to pair up with the first to get you a 1TB RAID-0 config.

[badbadbad]

Cool. I love the options. Might be stuck with option 1 for a while until the GTX880 becomes readily available. But if I have enough for another EVO and the GPU isn't within reach yet, I might just go with option 3.

Regarding option 2, if I go with the PM851 (the rebadged 840 pros, I'm assuming), would I have to use an mSATA to SATA adapter? Just worried about adding more areas of unreliability since it'll be in Raid-0.

I can tolerate a little stretch in expenses if the result is more reliable. Is a 2x256Gb Raid-0 really the better option, or will 2x500Gb be just as reliable?

2x500GB is ideal. The 500GB units tend to run faster than the 250/256GB ones. Only limiting factor is cost.

Yes, you'd need a mSATA-to-SATA adapter if getting a mSATA SSD. You'd have to make your own enquiries whether they support SATA-III. Each time you add an adapter you decrease the signalling integrity. Meaning it may well be that your mSATA SSDs could only operate at SATA-II speed over the adapter which pretty much erases the benefit of RAID-0. Not sure.. haven't gone down that path.

[badbadbad]

Yeah, gotta be careful about the support of some adapters. I did comment once about how Raid-0 in a Dual mSATA-to-SATA adapter would not work. Almost got me to go down that path. I guess it's option 1 or 3 then.

About the EC slot, did anyone manage to follow-up Kenglish's comment in boosting the PCH?

I do not know if this BCLK overclocking also overclocks the PCH PCI-E for eGPUs. It would be nice if someone could test PCI-E bandwidth in SANDRA with a BCLK overclock to verify if it does or not. If not I can provide an additional mod which definitely will overclock the PCH PCI-E.

I can try to test this out with my stock CPU while my quadcore hasn't arrived yet, but I might need some guidance if I have to troubleshoot.

Hi guys,

Just to report that I already got my 2570p from ebay for 367€ incl. shipment, with i5 3340M@ 2,7Ghz and 4GB Ram 1333 and a 320GB 7200rpm HDD.

I already upgraded it with a 128GB SSD Kingston V300, 2x 8GB Kingston 1600 and installed Windows 8.1.

I plugged in my EXP GDC V6 with my GTX750 ti OC from Asus and it runs really well but unlike with my Vaio VPCZ1 I had to do DSDT override (using bios F.45) to use both displays at the same time or the laptop screen would turn grey with low resolution and I had to use setup1,30 to do a 36 compression (same situation with an Acer Aspire 4920). The system boots so fast that I almost don't loose any time doing it.

I get an error code 10 in device manager about a High Definition Audio Controller, but audio is working so I don't think it's a problem.

My 3DMark06 score is 19637 (external screen). So I'm very happy with this machine. If only we could upgrade it's screen...

Proud to have you on-board brother!

In a few days, Aliexpress will be having a Super Sale, so maybe we can capitalize on the lower costs for even better upgrades.

Just as an aside, how is the F.45 bios working for you? I'm thinking of staying with the F.44 since I'm worried that an updated Bios might patch the WLAN and return the Whitelist.

F.45 has the same buggy/broken WWLAN whitelist functionality as F.44. Something I tested just before offloading my 2570P. You can flash to F.45 and not break you BCM4352 functionality.

[badbadbad]

Thanks @Tech Inferno Fan.

Just some precautionary questions. Would updating to F.45 mean that I would have to get another ME Firmware to flash/reflash XTU? Or will the old one just work as well?

And if XTU is already working, will you get bricked for updating to F.45? :fingerscrossed:

So far so good. I guess Tech Inferno Fan already answered. Good to know by the way.

I noticed that we can downgrade from bios F.44 to F.42 so I think we can downgrade bios version when we want. I was surprised, usually its not this easy if at all possible.

I had a strange bug with my moded 337.88 verde drivers. I couldn't have just the external display and the laptop display off, both of them had to be on. I've already modded the new 340.52, I will test them and see what happens.

[Tech Inferno Fan]

I started with bios F.42 and then flashed the modified OC ME FW, ensuring the XTU BCLK slider worked. Then after upgrading to F.44 the slider continued to work, as did it when I updated to F.45. The ME FW could potentially be updated by HP during a bios upgrade but in that sequence of bios updates it wasn't.

[badbadbad]

Ok. Thanks. I guess I can stay with F.45 indefinitely unless the update is really necessitated.

Looks like user @Uftherr is offloading his 2570P. Currently listing it and his GTX670 eGPU in a EXP GDC V6 at 1800 euro on ebay-DE : eGPU-Set (HP 2570p, EXP GDCv6), externe Grafikkarte am Notebook | eBay.

Is that a realistic pricepoint for a 2570P Europe? I mean, you can get a 2570P from the US for US$400 with international shipping. Add RAM, US$200 CPU, US$99 EXP GDC, US$200 GTX670 and it would be ~US$1k. Or better yet, have you considered offloading the 2570P separately to the eGPU?

Could you also contribute your i7-3720QM's TDP/VID table so can be included at http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-37.html#post77432 . That CPU could potentially give the best matched TDP/VID output. We only have one current sample. Maybe yours does better highlighting the i7-3720QM as being a standout bang-per-buck i7-quad for 2570P systems?

Well, there's an eBay link now where someone is auctioning the 2570P for $99 USD. Price is now $200+ with a few hours to go.

Nice one. It's US$214 atm, coming with an international shipping option. It's US$60 international shipping to Australia.

Great value for our European 2570P compared to the 1800 euro (US$2410) 2570P on ebay.de.
