Upgrading the Vostro 1700 to beyond maximum specs

WARNING: This post is very specific to an old laptop, probably only interesting to anyone looking to upgrade such a machine. I warned you.

I have an unhealthy obsession with “maxing out” machines, especially older ones. It was time for the chunky old Vostro 1700 that now runs Windows 7 instead of the version of Windows XP I installed previously. From various forums I gathered that the laptop’s beefiest configuration from the factory was a Core 2 Duo T9300 CPU and 4 gigs of RAM, available towards the end of its production run.

The Vostro 1700 features an excellent keyboard (for my taste), and a clear and bright full HD matte finish 17″ LCD screen, which is the reason I keep it around. It does Steam in-home streaming reasonably well, and remote desktop to more powerful machines is of course flawless.

Anyway, not going to settle for the factory maximum, I decided to get hold of some memory and a C2D CPU from eBay. The result was a C2D T9500 CPU, which is a tad faster than the T9300, but with similar power requirements, as well as two sticks of Samsung 4GB DDR2 SODIMM ram, which would have been stupid expensive back in the day. These guys estimate well over a hundred dollars, even from eBay, which this machine frankly isn’t worth, but today it’s a mere fraction of that.

Annoyingly, it turns out that even with the most recent BIOS, version A07, 8GB RAM makes the machine hang during initialization. I was, however, able to get 4+2GB to run, after it spent around 10 minutes thinking about it at first boot. For some reason the thing takes ages to boot the first time after a change in the amount of system RAM.

Now for some before and after shots of the Vostro 1700, first with 4 gigs of ram and a T8300 CPU, and then with 6 gigs and the T9500.

    Thanks. I want to do this to my old Vostro 1700. Any further details that might be helpful? Ebay seem to have a lot of C2D T9500’s for sale

      Well, just be really careful, and make sure you keep track of the countless amount of screws. Also, make sure you have some thermal paste ready, as you’ll want to replace what’s there just as on a desktop computer. The machine itself comes apart quite easily. It helps if you’ve built computers before.

    Was your 1700 a 32 bit CPU before?

  • Rex says:

    What did you do with the 4 gb ddr2 that you did not use in the 1700? You said 8 gb had issues so you settled for 6. where is the other 4? Did you sell it?

    • bolt says:

      I honestly have no idea. It’s either in my huge pile of old memory sticks, or I put it in something else.
      Before you ask me to ship something to you, keep in mind that I live in Norway. Shipping prices are ridiculous.

  • REX says:

    I see. Well my only other option is to buy from ebay and it seems China has the bulk of the 4 Gb mem sticks. My only gripe about that is they list the stick $1.25 plus shipping @ $25.00. I am not sure if that is a result of the new tariffs on imports or if it is business as usual. Is the memory stick a 200 pin? I am having difficulty knowing the correct stick to get on ebay. one that I was looking at was listed as a 4GB PC2-5300S DDR2-667 MHz 200PIN RAM SO-DIMM

    • bolt says:

      The 4GB stick that sits in my Vostro 1700 is marked “Samsung 4GB 2Rx8 PC2 – 6400S – 666 – 12 – D3“, model number M470T5267AZ3-CF7
      There do seem to be a few of them on eBay

  • Rex says:

    Did you buy your T9500 from China? Do you think they are trustworthy?

    • bolt says:

      I got it from eBay. The title said “Intel Core 2 Duo T9500 2.6 GHz (EC80576GG0646M) CPU Processor 800 MHz/6MB”.
      I trust PayPal’s customer complaints system, and VISA has a similar deal if you pay with that. I’ve gotten my money back several times from each over the years, so I’m not at all worried about internet sales.

      Keep in mind, the Vostro 1700 is an ancient machine at this point. I did this because it’s a hobby, and not a big expense. The Vostro 1700 is never going to be quick. It’ll be noticeably faster for sure, but nowhere near even a cheap machine today. If you want to actually be productive, you’re much better off investing in a used or refurbished machine from your local Craigslist variant, from one of those shops that buy bulk used business machines and clean them up.

    Good point. I know the 1700 is quite obsolete now and I cant really afford to spend $250-$500 for a cheap new machine. and its still cheaper to update to 6 GB mem and a T9500 and a 500 GB HD and get a couple more years out of it. I believe it can still be a productive machine. I am not a high end Gamer just a Solid Works Designer and the new cheap machines are fast but not able to run Solid Works because of the video card requirements. This upgrade will help enough to run SW2015 better. Although it ran it fine before as long as the assembly was not too large. maybe it will even run SW 2019.
    I like the idea of buying a referb. Maybe I will look at some high end older but not to old machines just to see what’s out there.
