VAIO UX490 modded with U7600 Core 2 Duo, may be the world’s fastest UMPC

Posted on 26 September 2008, Last updated on 11 November 2019 by

A few weeks ago we told you about the VAIO UX280 that was modded with the 1.2GHz U7600 ULV processor and scored an impressive 30,069 in the Crystal Mark benchmark program. This time it is a UX490, the latest UX model, which was modded with the U7600 and the Crystal Mark scores are something to behold. MicroPCTalk forum member Ahn did the modification to another forum member’s UX490 (computercowboy), which involved removing the 1.2GHz Core 2 Solo CPU, and putting in its place the 1.2Ghz Core 2 Duo U7600 ULV. After putting the unit back together, the unit scored an incredible 45,999 in Crystal Mark!

Take a look at the graphs comparing the UX280 U7600 to a factory UX490 and the modded UX490 U7600. The biggest reason that the UX490 U7600 scored a higher total than the UX280 U7600 is the zippy 32GB SSD (compared to the UX280’s 40GB HDD). As you can see in the graphs below, the UX490 U7600 did some serious work in the FPU category and scored much higher than the UX280 U7600. I’m not quite sure what factor caused the large jump in FPU score. The most likely bet seems to be the contrast of SSD vs. HDD, but to my limited knowledge, FPU is all done on the CPU so the SSD shouldn’t have a large affect on the FPU score. Does anyone have any other guesses?

I think I can say for sure that computercowboy’s UX490 is the fastest (non-overclocked, thanks Brett) ultra mobile PC out there, and probably has a higher power:volume ratio than many full sized computers out there. Are there any challengers to compete for the throne?

    Everun Note with Mitron 100Mb/sec read, 100Mb/sec write SSD gets 51,159 …
    but, that same SSD would fit in the UX :)

    sorry, that was a mistake

  3. Brett says:

    it’s overclocked and maybe not stable

    the incredible HULK among UMPCs! :-D

    i wonder if they can even increase the score by soldering more memory onto the mainboard, because i remember they had found a proper ram module..

    I am about to get my samsung q1 ultra premium modded to an intel core2duo u7700 1.33Ghz,sure it will get alot improvement from original cpu which is the intel solo u1500,but I am kinda worried about the battery life,since the Q1UP has a 6cell battery that offers 6-7hours normal working time,so will that drop a lot after upgraded?
    anyone here can give me someideas will be appreciated,and I did hear Ahn and computercowboy mentioned theres no battery life decreased.BTW.since I upgrade my samsung q1up to 2gb ram,and aslo have a 64GB SSD replace the HDD,once I have the cpu upgraded,I will be able to break the record.

    My optimized VAIO UX benchmark with crystalmark is 70996. That is the fastest UMPC on the World !!!

    AND IT RUNS STABLE…

  8. bob says:

    what’s the spec on that VAIO UX that gave you the crystalmark score of 70996 ???

    I have an Mft optimized Win XP pro System with an Mtron SSD. The SSD througput is faster than the internal RAM. I have modified the original Bios and a faster wlan a b g n ubiquiti pcie card with modified antennas. Then i have soldered a bigger ram in it (2048 GB). The CPU is not modified because there is only a little bit more performance with a dual core ulv.

    Do you think the machine would run GNS3 and/or vmware ?
