    partial success K7T266 Pro2

    It's been a long wait, but I finally recapped this board and got a new CPU and RAM for it (I'd replaced the motherboard in the system it had been in...)

    (Prior thread: here )

    When I initially tried to POST this system, it complained that the CPU fan was not spinning...an obvious lie.

    Going into the Bios (AMI bios V3.5) the "Hardare Monitor" page hangs after displaying most of the information on the left side.

    I tried reflashing the BIOS to V3.7 (current latest on the MSI site). Now it seems to see the CPU fan OK, but the Hardware Monitor page still hangs.

    It displays all of the readings except that for the -5V.

    Anyone seen something like this? Is the motherboard dead? I've got an Athlon XP 2000+ procesor in it, which is supposed to run on a 133Mhz Front bus. Instead it's set to a 100Mhz FB. and since the Hardware Monitor page hangs, I can't make any adjustments to the settings there...which is where these frequency settings are.

      This sort of flakiness is sometimes seen when running a Thoroughbred processor in a board that was only designed for a Palomino, or a T'bred B in a board that only supports a Palomino/T'bred A, or a Barton in a board which only supports up to a T'Bred B.

      I had this happen once on a K7SEM derivative, and the board also ate the T' bred B CPU after a while. The old pains of Athlon-era flakiness are no longer there in S754/S939/AM2 - good riddance.

          I guess you've replaced every Tayeh and Lelon - if not, replace them first. Also, try replacing the KZGs as well, with non-aqueous replacements: LXY/LXZ or Nichicon PW or Panasonic FC/FK.

              I have a modded BIOS for this -5V hang, I just need to find where it is in my CDs.

              To run Thoroughbred Athlon or Barton in this board you need to do the known C37 capacitor fix, ie, remove it with soldering iron with a lot of care.

              more info here:
              MSI forum K7T266Pro2-RU with Athlon 2200+

              C37 fix simple description

              Read it all before doing fix ( it is a very looong thread, therefore patience )

              Ask me for my modded BIOS 3.7, I am searching...

                  Without this C37mod, if you try to use any Tbred or Barton you will get 4 RED LEDs on D-Bracket.

                  Another thing, don't try to remove C37 with any sharp tool as some users had done in MSI forum. This procedure can damage under it.

                  Still searching BIOS...

                          Wow! Thanks for all the responses

                          RE: T'bred... I was careful to get a Palamino Athlon as the MSI site had stated that the board worked with Palamino's up to 2100+. This is a palamino (i.e. square die casing) processor.

                          I'll try the modded BIOS right away! Thank you for finding it.

                              Thank you, Danten!!! That modified BIOS worked perfectly. I was able to set the FSB to 133 and the BIOS now detects the CPU as an Athlon XP 2000+.

                                  I'm glad to know that it worked well. I supposed this -5V hang problem was restricted to me and my motherboard only and I done this mod to myself.

                                  I never thought this could affected other owners. Well I hope this BIOS can help others too, I will publish in my blog so google can index it. I don't know if index this forum.

                                      Dante,

                                      I am having one other problem, that I also see some others have had in the past with this motherboard (http://www.anandtech.com/mb/showdoc.html?i=1578&p=15). Every time I try a warm reboot, it fails the keyboard check. Cold boots seem to be fine.

                                      Any ideas for a workaround? I didn't see anything in the BIOS to allow bypassing the check (and the articles also mentioned no support for that.)

                                          K7T266 Pro2 (MSI MS-6380), damaged caps!
                                          by Tormi2k
                                          Hi Guys!

                                          For my retro machine I was looking for a mainboard with 3.3V AGP support. Luckily I found several being one a K7T266 Pro2 from MSI. The board runs fine, but after a brief visual inspection I could find physically damaged caps around the socket area. My guess is that during the installation of the CPU cooler they got damaged. To be on the save side I want to replace them.
                                          My main concern are the five RUBYCON MBZ 2200uf, 6.3V. But if I start the process I am also looking on the other ones around the socket area.

                                          In total there are

                                          Partial Success Repairing Vertical White Bands on HP Z30i
                                          by lowteq
                                          Hello.

                                          I was given a HP Z30i LCD computer monitor that had several white wide vertical bands on it. I had another Z30i that was working and after a lot of swapping of components I found that the logic board, TCON board and associated ribbon cables were healthy. The problem was the ribbon cables that go from a long slender PCB across the top of the panel onto the panel itself. The problem connection was on the PCB side not the glass panel side. These ribbon cables are attached with some kind of heat set adhesive.

                                          I'm aware that this type of problem usually isn't repairable...

                                          Hello everyone,
                                          The operating system often hangs after any graphics operation like scroll/zoom/menu open/button click. It is the same after swapping all parts (CPUs: dual Opteron 2216 or 8435, RAM: 8x1GB or 8x4GB, power supply : 800W or 1000W, graphics card : original Quadro FX 3500 replaced with GeForce 7300 LE to decrease power) one at a time, and trying several operating systems (Windows 7/10, Linux, FreeBSD; 32 and 64 bit versions of all of them). But if the motherboard has been sleeping for months/years, the first few minutes are more stable before it warms up. This seems to come with...

                                          Hi, I seem to have a partial short on the VCC3SW circuit coming from RTCVCC.
                                          • VCC3SW initially measures about 1.1V.
                                          • RTCVCC to ground measures approximately 9 ohms, but it does seem to fluctuate as I have measured it at 2 ohms.
                                          • There is no apparent water damage (or any other damage) on the board.
                                          • Removing PD0001 disconnects RTCVCC from VCC3SW and VCC3SW is back to 3.3V.
                                          • R1301 measures about 1M measured directly on board
