CPU upgrade to W510 Question

#1 Post by ThomasAquinas » Mon Jan 13, 2020 9:44 pm

I know this a noob question. Please just give me some basic idea on where and how to get the right answer to this question. It has been a awhile since I was really active in IT. I have this old Lenovo w510 which is installed a SSD drive into and yet it is ridiculous slow. I put an SSD drive and it is still painfully slow doing anything other than minor word processing. The specs are: Intel Core i7 720QM @ 1.60GHz, on LENOVO 4389AN7 motherboard.
It came with 8.00GB Dual-Channel DDR3 @ 531MHz.

I have seen on the Lenovo site that the w510 also came with different CPU and it is highest two models were Intel® Core™ i7 processor i7-820QM (1.73 GHz) with quad-core and then Intel® Core™ i7 processor i7-920XM (2.00 GHz) with quad-core. Can I switch the CPU without changing the motherboard? I can’t find anything to tell me if the two higher i7 are on the same motherboard as my 720qm?
Thanks for your help!

Welcome to the forum!

Yes, you can swap out the CPU on W510 but:

a) Yours is pretty much the top of the line CPU of that era and

b) I would venture a guess that the lack of speed is likely software-related, and not due to any hardware limitation.

Which OS are you running ?

Good luck.

Hi i am running windows 7.
I thought that there would be a significant performance improvement
between 720qm with 1.60 Ghz vs. either the 820qm with 1.73 GHz or the 920xm with 2.00 GHz.
I can't figure out what why this is so slow

Sounds more like a bad OS installation, your machine should fly!
Make sure you have a 64-bit OS.

Perhaps see your CPU temps too using TPFancontrol. It could also be that the i7 or discrete GPU (if you have one) is throttling the entire time. Last time I was dealing with a T520 running league of legends at 2fps it was because the thermal paste is next to non-existent. Better safe than sorry because there is only a numbered amount of hours an i7 can run at such throttling temps before it just dies.

Ok, I have upgraded to windows 10 and there is not performance improvement. I know that the I7-720qm is the lowest CPU which came with W510. Do I need to worry about having to upgrade motherboard if I purchase the I7-820Qm and switch it with the old CPU? the highest I7 that came with the w510 was the I7-940XM basically can i upgrade without issue?Image

You can upgrade the CPU without changing the board.

Have you done a clean install of W10 or an upgrade from the previous OS ?

That machine shouldn't feel slow. Plenty of guts left in that hardware, unless you're doing video rendering 24/7...

Thank you for your reply. So I took my old laptop Hard drive from an Inspiron 1545 with windows 7 and I unload a lot of programs and documents.. I got it down to maybe 100 gigs of data out of a 500 gig hard drive. This includes system files, etc. Than I imaged the drive to an SSD and put the SSD into this laptop. I had to do this because I didn't have a functioning backup for the failing hard drive. The w510 recognized the SSD and booted no problem. I later flashed the bios because there was a new update in like 2013. And so the computer sees the hard drive and booted fine right away. in device manager it sees all the hardware for this laptop and doesn't appear to be an issue. I than download the MS media creation tool and upgrade to windows 10. This same laptop had windows 7 on it and the hard drive failed, however it ran slows a [censored] then too. With this new installation it still prone to hanging and getting really slow when I am multitasking between word documents and email, etc. Whenever i check the task manager, I noticed the CPU getting close to 100%. The memory is usually fine at 5 out of 8 GIGs in use. However, my network card is very active and working like crazy too. I figured it was CPU since it is now running windows 10 and MS 2016, etc. It was slow as [censored] when i had the hard drive that it came with in it, i just assumed that upgrading to SSD would improve functionality and fix the problem. I have definitely seen improvements with the SSD.

So when I put the SSD in I noticed performance improvements in the computer boot up time, time files get saved or transferred, etc. What did not change is when I have like 15 firefox windows open and ms word running the bottom it taps out the CPU and things bottleneck. I use CoreCPU and I watch the temperature and it never really gets beyond 150 Fahrenheit. What do you think? I mean if I paused a lynda.com video in background and try typing out an email, it gets so slow...for example. It does this with any browser and I am usually looking up things online from a school paper, etc. I am not doing incredibly taxing tings. I have also shut off all extensions in my browsers and killed most startup programs and leave like nothing in the taskbar running. I check the processes in task manager and it is always the browser hogging up the CPU either Chrome or Firefox whichever I am using.

Sorry for long response. It is late and I am exhausted and I wanted to provide as much info as possible.

What is your (supposed) internet speed?
Are there any wifi-limitations?
Bad/corroded contacts?
When you install W10, apparently it takes ages to install all its updates, while running near 100% CPU.
However, instead of upgrading W7 to W10, do a complete, fresh install from scratch.
If you don't fancy W10, there is also W8.1 available, which is still supported for a few more years, plus of course Linux.

If installing Win10, one should always install the latest milestone release - this way there are fewer updates to do.

Hello,
Ok so I already had installed windows 10. It actually runs the same way that windows 7 did which it would slow down when I am multitasking. My wifi speeds I think are good since I use it on my tablet and it flies. Moreover, I notice when i download videos from lynda.com, I usually get 2-3 mb a second. What else should I check for and are their any program which would run better benchmark tests that I should try? Incidentally, I found a I7 920xm cpu on ebay for like $50. It appears to be the highest cpu which shipped with the w510. I was thinking of spending the money and trying it to see if I notice performance upgrades. Would anyone caution me before doing this? Is this a worthwhile experiment to try?

Have you monitored the clock speed of each CPU core as you multitask? According to cpu-world.com:
Maximum turbo frequency:
2800 MHz (1 core)
2400 MHz (2 cores)
1733 MHz (3 or 4 cores)
1.733 GHz when fully loaded isn't fast.

A 920XM could give a noticeable performance increase, with a 30% clock speed increase with 4 cores loaded:
Maximum turbo frequency
3200 MHz (1 core)
3067 MHz (2 cores)
2267 MHz (3 or 4 cores)
But the costs are higher CPU temps and power consumption. While it's a 55W TDP CPU, actual power draw can be much higher:
Minimum/Maximum power dissipation
2.6 Watt (Package C6 state) / 120.49 Watt (peak)
2.6 Watt (Package C6 state) / 96.25 Watt (sustained)
These figures are from cpu-world.com.

For comparison, here are the figures for the i7-720QM:
2.6 Watt (Package C6 state) / 100.38 Watt (peak)
2.6 Watt (Package C6 state) / 79.66 Watt (sustained)
Daily driver: X220 4291-C91 i7-2620M

hi axur-delmeria,
What would you use to monitor those CPU cores?

Ok one more question. so it is established that this laptop speed is driving me crazy. If overheating is the only real drawback would invest in a tabletop laptop cooling pad be helpful?

Also I found a cpu on ebay. Should I be concerned by the presence of this much thermal paste? https://www.ebay.com/itm/Intel-Quad-Cor ... 3480809727

Alright guys. I just replaced my old cpu i7-740qm with the i7-940xm. I notice a bit of a performance increase..

i will keep you posted
