    I have an hp dv4-1147cl with windows 7 64-bit. I just upgraded from vista and when I did that, HP made me upgrade hte BIOS and I wasn't thinking when I did it. Anyway, I have flashed like every possible BIOS to get it to recognize slot #2...both modules work, but the BIOS won't recognize slot #2. Also, in the BIOS it says my system board ID is 30F8, but when upgrading the BIOS with Insyde, it says my current version is 30F7 and upgrades it to the newest version of 30F7. No matter what BIOS version I download for my specific laptop from hp.com , there is nothing there for 30F8, it is all for 30F7. everything is working fine except that the slot #2 memory RAM slot isn't working. If the BIOS had Memory Remapping option or somethign like that, I wouldn't be asking about this...but is there any way to mod this BIOS? Why can't I find anything for 30F8? HELP! PLEASE!

    BIOS version 30F7 is correct for system board 30F8.

    Try this.

    1. Turn the laptop off, disconnect the AC adapter AND the main battery. Hold down the power button for 5 seconds then release it. Reconnect just the AC adapter and see if you have your RAM back if not then goto 2.
    2. Turn the laptop off, disconnect the AC adapter, the main battery should already be disconnected. Remove the small panel underneath which houses the small RTC battery and disconnect it for 10 seconds. Reconnect the TC battery and AC adapter and try again.

    If that didn't work then possibly the RAM is making a bad connection with the connector. Remove the module and try clean the contact area. When replacing the module, wiggle it up and down a little in the connector before pushing it home.

    This was awfully stupid but at this point I dont care...I tried reseating the RAM while browsing the internet. Not slot #1 that works, I wont touch that, but slot #2, and the system does nothing, I wiggle, I do everything to try to get the computer to glitch because more RAM has been introduced. Is there anything else I can do??????? Just to clarify, this all happened when I was required by HP to update from F22 BIOS to F44 BIOS while upgrading to Windows 7. I honestly think that when when I flashed from the F22 to the F44, something went bad and I don't know how to undo it. I have turned everything off, pulled everything out and held the power button for 1 minute to drain anythign left, and I also did the RTC battery thing leaving it unplugged overnight and no success. It's not even that slot #2 is causing errors or problems, its as though it doesn't even exist. I don't understand this, this is very very weird. I would think that if something were wrong with it, I'd get an error for trying to seat RAM into a faulty slot, but nothing, even while running the OS. Surely there must be a genius here that has some sort of solution. I challenge someone to figure this out. haha, I hope that will work.

    Okay, that's a shame. When did you update the BIOS though, F55 is the latest for W7 and before that it's F30. They did have some between F30 and F55 but they were removed some time ago by HP for whatever reason. I've personally not been impressed by their BIOS with so many updates and what seems to be hidden agenda's with them.

    Okay, back to the RAM, when you first power up and the BIOS doesn't find a module in a socket or decides to disable it, is to remove the signals to the connector. You should still be able to access the eeprom SPD data though. You could try something like CPU-z to check if it can see two modules even though you cannot access the memory on one of them. This means that you will have to power off the laptop if it's a connection problem to get it to work again, probably safer wiggling while the powers off anyway. ;)

    I forgot to mention trying F9 in the BIOS setup just on the off chance.
    Here's a link to the F55 BIOS, couldn't tell you how good it is but since it's been up there a while I would imagine it shouldn't be too bad. :D

    While I wait for a virusscan and windows updates to finish, which is taking 8723489273489273492874928347324 years with 2GB of RAM, I tried CPU-Z and when I go to memory and select slot #2, EVERYTHING is greyed out and empty. I don't know what that means. Any ideas? I'll try the F9 thing, but I already tried to reset to defaults numerous times. I'll still try what you suggested again and do the wiggling thing whiel its off :). Is there a chance that the BIOS is doing this? You seem to know about these BIOS, so I wonder, is there a way to get more options in the BIOS. I suspect you would have told me that already, but I've literally got nothing left to do except spend $400 on a new motherboard, or $150 at least on a 4GB RAM module which will forever be the maximum I can put on this 1 year old computer.

    I FOUND THIS IN THE CPU-Z OUTPUT TEXT FILE.
    MCHBAR I/O Base address0x0FED10000
    MCHBAR I/O Size4096
    what does that mean? 4096? isn't that referring to 2 sticks? I've yet to see anything that might be referencing that.

    Seems like your laptop BIOS is not able to read the SPD data which means the BIOS doesn't know what's in that slot so is not enabling it. I take it you have already tried each module in turn in slot 1 with nothing in slot 2 and they both worked. Have you ever had both modules working or is this a memory upgrade?

    I don't know about those 4GB modules, they are still very expensive and with DDR3 becoming more popular by the day may never come down to a reasonable price. You are able to use up to 8GB in that laptop if you can get both slots working.

    The MCHBAR I/O is just a memory mapped I/O range from 0xFED10000 and the 4096 is the length in bytes. You should only need to check at the SPD tab of CPU-Z.

    I don't know of any BIOS options that would help you and I wouldn't think the BIOS would be a problem but I don't know for sure.

    If the laptop can not read the SPD data in slot 2 the BIOS is going to ignore that module.

    Is there any sort of mod with memory remapping or something that I can try? ahhhhhhhhhhhhhhhh

    I'm almost considering a 4GB module

    I was thinking even though my video card has 512 dedicated RAM, it shares some of the RAM. I don't think its using that RAM module, but I think the video card might have something to do with it. Is there some sort of onboard video card on my computer that I can use instead of the NVIDIA video card?

    Usually when there is a update for your BIOS, it only affect the fan control, not much of a drastic change from the old version of bios and the new version. Once you update your bios, I don't think it will let you "downgrade"

    You mention that your bios do not see the other memory stick, did you upgrade your memory and is it the same spec for both of the memory stick.
