    The VPN may not have uninstalled completely, leaving their DNS settings in place. Or, indeed, the message might actually be correct (why not?), so check which primary and secondary DNS addresses are currently set:

    Even if these two are up and running, they still might not be reachable from your location, so try setting something like google's DNS manually and see if these do get a response. They're 8.8.8.8 and 8.8.4.4, respectively:

    Anybody have SetFSB for the Dragon?
    I'll be back home on the next week to go on with the mod, so I hope to post many things soon

    I was looking through the PM965 datasheet and found an interesting sentence:
    upload_2019-4-27_15-8-3.png

    Having that said, most likely it means that it should support up to 64GB of RAM. This is very interesting and worth trying, though going to be not easy. The chipset supports 2Gbit RAM chips, though I've found 4Gbit DDR2 1066 MHz RAM chips at the market as ECB440ABACN from Elpida/Micron. Those are hard to find and different from the ones I've reported recently.
    http://web.archive.org/web/20111104082933/http://www.elpida.com/en/news/2011/04-07.html

    But I'm not sure if PM965 can address the whole address space of a 4Gbit chip.
    4GB RAM sticks have 16 chips. If we want to assembly a 32GB stick, we would need 128 chips (64 on each side) in total. Such a stick would become nearly 8 times longer (4 times longer in case of using 4Gbit RAM) than a standard one. Anyway, I'd like to try at least a 8GB stick for the start.:D

    I guess we can drive the FSB:RAM divider by playing around with the BSEL pins of the north bridge thus making it thinking a CPU of certain FSB has been installed. But as PM965 supports 533/667/800FSB (133/166/200MHz) CPUs and 533/667 (266/333MHz) RAM, my guess is that 1:1 (i.e. no divider) is not possible. Not sure if FSB:RAM divider can be controlled via BIOS in our case.

    I've done some basic, but the most correct calculations regarding data transfer rates of each bus. Here's an example of one for 8800M:
    VRAM bus width is 256bit (8 RAM chips 32 bits each) x 1600MHz (VRAM freq. 800MHz x 2 due to Double Data Rate RAM) = 256bit x 1600000000 Hertz = 409600000000 bits/s.
    Translate into MByte/s (GByte/s):
    409600000000 / 8 (bits to bytes) = 51200000000 bytes/s
    51200000000 / 1024 / 1024 = 48828,125 MBytes/s
    48828,125 / 1024 = 47,68 GBytes/s
    GPU-Z does wrong calculations, thus it displays the memory bus bandwidth as 51.1 GB/s for 8800M because it divided 51200000000 by 1000 instead of 1024. Not a big deal though.

    Let's forget 8800M for a while and mention RAM and FSB.
    533MHz RAM speed would be the best choice for operating at the same speed as a 1066FSB CPU. None of them would be a bottleneck for each other and that would be a perfect setup. But due to the divider, we cannot reach that (at least for now).

    Values for PCI Express and SATA were taken from Wikipedia because I couldn't find the number of bits transferred at a time.
    DMI bus is a dedicated 4bit-wide PCI Express connection, so having the data transfer rate and bus width values I could calculate the frequency value. Though Scott Mueller in his book "Upgrading and Repairing PCs" says that DMI works at 250GHz @ 1GByte/s speed, it must be a typo because PCI Express 1.1 frequency is based on 2.5GHz and therefore my calculations showed that the transfer rate in this case should be 1192MBytes/s. Otherwise, based on his info (250GHz), it should have been approx. 116GBytes/s rate. So I think he made a mistake.

    The following picture clearly shows that the 16X PCIE bus for 8800M is a bottleneck in the system due to being PCIe 1.1. and thus may cause delays when working with the a graphics card at full load. If it were PCIe 2.0, it would be twice faster and that would perfectly fit the setup if we could disable the FSB:RAM divider.

    Just found this and understood why the AC LED doesn't turn on when connecting an AC adapter with the BIOS chip off or faulty BIOS. From ICH8 datasheet:
    Not sure if this check happens after OS shutdown.

    My god this thread is STILL going. HP should take note and make a new version, I miss mine.

    I tried to get fast UDMA modes to work, but it seems like it all up to the Dragon's BIOS. It's not enabled there, IDE devices cannot work in the fast mode, though tried to emulate a 80 pin IDE cable connection.
    I kept getting RAM errors in memtest, so I increased 1.05v to 1.1v on the north bridge's core. As CPU and the south bridge share the same 1.05v bus, it was impossible to increase the voltage independently. And I wanted to increase it up to 1.15v which is max for the north bridge, but the CPU was a bottleneck here.
    It didn't help, so I raised up another bus of 1.25v to 1.4v by replacing R172 with 24,3 KOhm. It had relation to RAM, but didn't work out too.
    Either my PM965 is defective or it cannot handle a 266MHz FSB. So the next thing I'm going to try out is replacing the north bridge with a new one or getting another Dragon board.
    I'm wondering if it was working fine for Lenovo T61 modders.

    So I'm begging anybody, expecially @RickiBerlin to do the 1066 mod to find out if it will go fine for you.
    When modding the north bridge for 1066, removing R520 and using it for hooking up 1 wire from VCCP to CPU_BSEL1 on the north bridge is not enough. There's VCCP attached through R227 to the CPU_BSEL1. It's forcing the board to work at 800 and 667, though it seems to not be working when installing a 1066 CPU. A useless thing, so I decided to remove it.

    I've done the voltmod after having changed the DRAM:FSB divider to decrease the RAM frequency down to DDR2-708 (354MHz) by playing around with RAM timings and FSB. Here's a table of dividers:
    upload_2019-5-8_13-24-8.png

    For FSB 667 and RAM 533, divider is 8:5
    For FSB 667 and RAM 667, divider is 2:1
    For FSB 800 and RAM 533, divider is 4:3
    For FSB 800 and RAM 667, divider is 5:3

    PM965 supports 533FSB CPUs, but BIOS doesn't. Therefore, the Dragon cannot start at 533FSB.

    The best divider to get the lowest RAM frequency is 4:3. So in this case DDR2-800 will be working as DDR2-708 at 354MHz, if FSB is 800 and flash the RAM for 322MHz as shown on the screenshots to make PM965 set the needed divider.
    Here's a full setup
    [​IMG][​IMG] [​IMG]

    This is the setup for RAM that should be flashed with Thaiphoon or whatever flasher you have
    [​IMG]

    But as you can see, the RAM is working at CL4 as PM965 thinks its DDR2-533 and thus is forcing RAM to work at CL4. Let me know if anybody know how to fix this.

    I had and opportunity to try out the XB3000 docking station. Touch control didn't respond and the sound quality is poor, worse than of the Dragon. Everything else seemed to work fine.
    No update on FX3700 yet.

    I've got a good news. I got RAM to pass with no errors in memtest by increasing 1.8 voltage for RAM up to 2.04v because if the RAM is running at higher clocks, but with lower timings, it will be consuming more power as the RAM has been overclocked in this case.
    Just replace R148 with 51KOhm to increase the voltage.

    RAM chips got quite hot when I was running memtest, so we would need to buy some RAM heatsinks.

    I've decreased 2.04v to 1.97v. That's the lowest voltage that doesn't cause errors in memtest and the max RAM temperature could reach up to 67°C during the test.
    The overheating issue that happened to X9100 seems to be related to the motherboard position. When vertical, it can cause the issue. Not sure if it was fake or real, no idea if its up to this particular CPU. My board seems to be screwed up, but still alive for doing the stuff.
    X9100 is running pretty cool. The max temp during gaming was 55°C at its native clocks even after raising up VCCP by 0,05v. 29°C when no load.
    Due to BIOS/chipset forcing RAM to work at CL4, I've flashed the timings which correspond with JEDEC standards
