(7) What motherboards work properly with a mobile Athlon 64?
As of right now, only the below listed motherboards are confirmed to work to varying degrees; with the worst offenders requiring software hacks. Please note that the DTR and Mobile and True Mobile CPUs (the latter two are the "mobile CPUs" referred to in the rest of the paragraph) have different microcode. At the current time the implication of this is not fully known. Upon initial testing, it seems that support for a DTR CPU does not guarantee proper support for mobile CPUs (e.g. the CPU may be properly recognized but multiplier and/or voltage may no longer be modifiable.) On the other hand, support for mobile CPUs seems to indicate full support for the DTR CPUs. Again, these are just initial findings and more compatability testing is needed before this can be confirmed. In the future more motherboards will be added should they be found to be compatible with the mobile Athlon 64 processor.

AGP/PCI lock = working AGP/PCI lock. This allows for maximum overclocking
FID = muliplier control, from 4x to the maximum multiplier of the particular CPU. Useful for those looking to eek out every last drop of performance through high HTT
HTT = hypertransport bus speed is adjustable. Think of this as a frontside bus speed. The processor speed is arrived at by multiplying the HTT by the FID
Vcore = CPU voltage is adjustable
Vdimm = memory voltage is adjustable
LDT = HTT multiplier is adjustable. Different than FID. Sometimes overclocking necessitates that you lower this.
(a) SiS 755/964
ASRock K8S8X [AGP/PCI Lock, FID 4x-Max, HTT adjust, VCore, LDT; Tested with Athlon 64 DTR 1.5v, Athlon 64 Mobile 1.4v] - If your shipping BIOS is 1.50 then the board will boot fine but lock down to a 4x multiplier (800Mhz speed). You'll also get an error and have to go into the BIOS. Discard changes and exit and it should continue the boot cycle. At that point you should already have a Win95/98 boot disk in there with another floppy with the flash program and the latest 1.70 BIOS. If your shipping BIOS is 1.60 you shouldn't have to do anything but if you're running a 1.4v mobile CPU you need to update to the latest 1.70 to allow multiplier control if desired. While the DTR will allow for use of the maximum 1.55v, the voltage remains locked at a maximum of 1.45v for the mobile 1.4v CPUs.
(b) nForce3-250; nForce3-250GB
Asus K8N-E [AGP/PCI Lock, FID 4x-Max, HTT Adjust, VCore, VDimm; Tested with Athlon 64 DTR 1.5v] - will boot with the shipping BIOS and runs smooth. Overclocking however seems to be an issue with the shipping BIOS. Upgrade to the 1004 BIOS and overclocking should be fine. Be advised that the backplate is *glued* on, which means it's tough to get off and you need to get it off. Using acetone or heating the adhesive up with a hairdryer should allow the backplate to be easily removed. Be careful and don't use sharp objects as they may damage the board.
Chaintech VNF3-250 Zenith Value Edition [AGP/PCI Lock, FID 4x-Max, HTT Adjust, VCore, VDimm, LDT; Tested with Athlon 64 DTR 1.5v, Athlon 64 Mobile 1.4v] - will NOT boot with shipping BIOS. What that means is that you have to get *another* DESKTOP CPU and flash to the 2004/7/29 BIOS found here:

Then swap out the desktop with the mobile chip. At that point the motherboard will boot but the CPU will lock down to a 4x multiplier (800Mhz) To correct this one needs to go into the Frequency/Voltage control menu in the BIOS and enable voltage adjustment and MANUALLY select the proper voltage for the chip. Then, in the same menu select the FID control and manually select the proper multiplier for the chip. Reboot and the problem should be solved.
DFI LANParty UT nF3-250Gb [AGP/PCI Lock, FID 4x-Max, HTT Adjust, VCore, VDimm, LDT; Tested with Athlon 64 DTR 1.5v, Athlon 64 Mobile 1.4v] - will work with shipping BIOS although there are reboot issues in that only once every 3-5 boots will the motherboard boot up properly. The issue seems to stem from the low voltage applied to the DTR upon boot. This hacked BIOS seems to fix the issue:

Epox 8KDA3+ [AGP/PCI Lock, VCore via vmod, VDimm, LDT; Tested with Athlon 64 DTR 1.5v] - will NOT boot with shipping BIOS. What that means is that you have to get *another* DESKTOP CPU and flash to the new 9/13/04 BIOS. Then, with the desktop CPU still in the mobo you need to enter the BIOS and set the multiplier to 4x. At that point switch out the desktop CPU with the DTR and boot up. The system will boot up to 800mhz at 1.1v. From there enter the BIOS and adjust voltage to 1.55v and then adjust FID according to your CPU's default speed and you should be set.
MSI K8N Neo Platinum [AGP/PCI Lock, FID 4x-Max, HTT Adjust, VCore, VDimm, LDT; Tested with Athlon 64 Mobile 1.4v] The board has some SERIOUS quality issues (there are too many problems to list but users are seeing everything from stability issues at stock, inability to get voltage to stay above 1.45v, only parttime working RAM divisors, flakey AGP/PCI locks, to multiplier and voltage settings that won't 'stick') Unfortunately, this is nothing new with MSI boards. What that means is that you may get a board that works fine but it is *much* more likely that you will get a board that is a big POS which will cause you to waste endless hours pulling out your hair trying (and failing) to get the board to work correctly. Until further notice, this motherboard is NOT a good choice to use with mobiles (or any other CPU for that matter.) The motherboard will boot with the shipping BIOS but the CPU will lock down to a 4x multiplier (800Mhz) To correct this one needs to update to the BETA bios 1.52 Please take note that the backplate is *glued* on, which means it's tough to get off and you need to get it off. Using acetone or heating the adhesive up with a hairdryer should allow the backplate to be easily removed. Be careful and don't use sharp objects as they may damage the board.
Soltek SL-K8AN2E-GR [AGP/PCI Lock, HTT Adjust, VCore, VDimm, LDT; Tested with Athlon 64 DTR 1.5v, Athlon 64 Mobile 1.2v] Any settings above 250 HTT will not take effect, even with the performance BIOS. However, it seems that with clockgen such settings do take effect. Otherwise, no major issues to report.
(c) nForce3-150
AOpen AK89 Max [AGP/PCI Lock, FID 4x-Max, HTT Adjust, VCore, VDimm, LDT; Tested with Athlon 64 Mobile 1.4v, Athlon 64 Mobile 1.2v] - the 1.4v mobile will boot. However, the 1.2v mobile will NOT boot with shipping BIOS. What that means is that you have to get *another* DESKTOP CPU and flash to the 1.07a BIOS. Then swap out the desktop with the mobile chip. At that point, with both CPU types, the motherboard will boot but the CPU will lock down to a 4x multiplier (800Mhz) and reduced voltage. To correct this one needs to go into the BIOS and enable voltage adjustment and MANUALLY select the proper voltage for the chip. Then, select the FID control and manually select the proper multiplier for the chip. Reboot and the problem should be solved. One reported quirk with the combination involves the HTT resetting after the computer is turned off and then cold booted; it does not appear to be an issue when the system is simply restarted.
Gigabyte GA-K8N Pro [AGP/PCI Lock, VCore, VDimm, LDT; Tested with Athlon 64 DTR 1.5v] - will boot with shipping BIOS. However, HTT adjust is not available in the BIOS, but rather must be selected in Windows using clockgen. Also, no multiplier selection is available. One reported quirk is that voltages above 1.5v don't get saved properly in the BIOS, thus the system cannot be restarted. Rather, a full power off and then reboot is needed at which point the user must reapply the voltage selection.
(d) VIA K8T800/8237
Asus K8V Deluxe [NO AGP/PCI Lock, HTT Adjust, VCore, VDimm; Tested with Athlon 64 DTR 1.5v, Athlon 64 Mobile 1.4v] - works fine out of the box. Correct speed and multiplier automatically selected by shipping and latest BIOS.
MSI K8T Neo-FIS2R [NO AGP/PCI Lock, HTT Adjust, VCore, VDimm; Tested with Athlon 64 DTR 1.5v] - will not boot initially; user must clear CMOS. System will then boot up with CPU voltage at 1.1v and unidentified speed. User must then go into the BIOS and set CPU voltage to the proper 1.5v and the correct speed is then recognized by the BIOS upon reboot. Must do a clean install of Windows after CPU is used.
