Different values for Video memory

  1. #11


    Hi my2cents,
    Thanks for the response, I was wondering why the memory management is better in HD3000 than in HD4000, my Acer Aspire 5750 has HD3000, it reports 128MB for dedicated video memory in BIOS and it shows the same amount under Adapter but in E1-571 which has HD4000, it reports 64MB in BIOS and in Adapter it shows 32MB.
    I am not a gamer and it doesn't bother me at all but I think I have found the answer, Intel says that the new graphics memory sizing is done by the OS( Windows8/8.1) and not by the Intel driver.
    Unless MS comes up with some update or perhaps in the next months update, I am out of luck as I can not change anything in BIOS, Acer has disabled any Advanced settings in BIOS.
    Thanks again for your suggestions and the link.

    Hi again brummyfan. Glad you are satisfied at this point; however, I still think the BIOS should be able to communicate the initial size on startup "if" the OS can communicate properly with the BIOS regarding that attribute. Moreover, I think my example proved that when I adjusted the initial size to 1024MBs and it worked; therefore, there was no communication breakdown. However, I'm guessing there is a communication breakdown between your BIOS and the Win 8.1 x64 OS. This may be due to a compatibility issue with your specific BIOS but I can't say that for sure. Your scrrensohot does look like an older vintage BIOS BTW. Is your model listed as Win 8.1 compatible? I'm also guessing in your specific case, the OS may just be defaulting to the minimum allocation because it didn't receive the minimum allocation from the BIOS correctly. Anyway, glad you are OK with the way it works. I just wanted to test it to see for myself.

    Cheers,

    Thanks my2cents, I went in to a local super store and was browsing, most of the laptops have only 32MB Dedicated video memory under adapter, so I guess that this may be due to increase the battery life of laptops.
    EDIT:
    Thanks for the link for Acer BIOS but I have checked and they didn't say anything about Video memory sizing, though 32MB is sufficient, how they manage to provide more Dedicated Video memory in HD3000 (older) than HD4000 (newer)

    Hey, maybe it is a laptop thingy. Maybe some other laptop users (with Intel HD graphics) will do a comparison to confirm your findings. Anyway, happy browsing!
