October 27, 200916 yr Just noticed in the motherboard book for my computer I purchased in June that the Gigabyte EP31-DS3L has a maximum DDR2 memory that it will support of 4GB. I must admit I find this surprising when more users are choosing more that 4GB.The board has the Intel LGA775 socket and supports the full range of Core2 Duo and Core2 Quad procesors. It has Intel chipsets P31/G31 and ICH7.Although 4GB is more than enough for my needs I'm curious as to what it is that limits the memory. Is it the BIOS and would an update do it or is it more than that?Is this unusual?Iain SmithRugby, UK
October 27, 200916 yr I would say the OS determines the amount you can use. An x64 OS could use 128GB of RAM I spose | My Liveries | FAA ZMP | PPL ASEL | | Windows 11 | MSI Z690 Tomahawk | 12700K 4.7GHz | MSI RTX 4080 | 64GB 6000 MHz DDR5 | 500GB Samsung 860 Evo SSD | 2x 2TB Samsung 970 Evo M.2 | EVGA 850W Gold | Corsair 5000X | HP G2 (VR) / LG 27" 1440p |
October 27, 200916 yr It could be just the BIOS (if it's an older board), or it could be a physical design limit, like the number of physical address lines in the hardware, which would be a hard limit. But if there's no BIOS update for >4 gb at this late date, it's very likely a hardware limitation.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO Bob Scott | President and CEO, AVSIM Inc ATP Gulfstream II-III-IV-V Sys1 (MSFS20+24/XPlane12+11): AMD 9800X3D, water 2x240mm, MSI MPG X670E Carbon, 64GB GSkill 6000/30, nVidia RTX4090FE Alienware AW3821DW 38" 21:9 GSync, 2x4TB Crucial T705 PCIe5 + 2x2TB Samsung 990 SSD, EVGA 1000P2 PSU, 12.9" iPad Pro Thrustmaster TCA Boeing Yoke, TCA Airbus Sidestick, Twin TCA Airbus Throttle quads, PFC Cirrus Pedals, Coolermaster HAF932 case Sys2 (P3Dv5/v4): i9-13900KS, water 2x360mm, ASUS Z790 Hero, 32GB GSkill 7800MHz CAS36, ASUS RTX4090 Samsung 55" JS8500 4K TV@60Hz, 3x 2TB WD SN850X 1x 4TB Crucial P3 M.2 NVME SSD, EVGA 1600T2 PSU Fiber link to Yamaha RX-V467 Home Theater Receiver, Polk/Klipsch 6" bookshelf speakers, Polk 12" subwoofer, 12.9" iPad Pro PFC yoke/throttle quad/pedals with custom Hall sensor retrofit, Thermaltake View 71 case, Stream Deck XL button box Sys3 (DCS/P3Dv4/ATS/ETS): AMD 7800X3D, MSI MPG X870E Carbon, Noctua NH-D15S, 64GB GSkill 6000/30, EVGA RTX3090 Alienware AW3420DW 34" 21:9 GSync, Corsair HX1000i PSU, 4TB Crucial T705 PCIe5 + 2TB Samsung 970Evo Plus, TM TCA Officer Pack, Saitek combat pedals, TM Warthog, TM RS300 FF wheel/pedals, Coolermaster HAF XB case

The fist one is your motherboard's chip set in fact the chip set really IS your computer it's what ties everything together and determends just about every detail about what you can and can not add to your system. Things like how much memory, how many disk drives what type of video cards(and how many) what type of CPU and a host of other things that go into a system. As I said above the chip set is VERY important. The next thing is your O.S. if it's a 32 bit O.S. then the maximum memory that can be supported is 4 gigabytes as that's largest number that can be coded with 32 bits.(Try multiplying 2 to the power of 32 to see what number you end up with) while a 64 bit O.S. could address several petabytes! A very largs number indeed.Hope the above is of some help to you.Dan Martin Flight OntarioSooke B.C. Canada
