Looking for modified bios and chipset/vdimm mod for non Tforce Biostar 6100-M9

[Dazed and Confused]

Is anyone aware of a chipset vmod and vdimm vmod for the Biostar Geforce 6100-M9 ?

If so please post links here if you don't mind as I really wanna get the absolute best performance out of this board ( even if it means shorteneing its life : )

 

[Dazed and Confused]

Just found out by actually using my eyes that the 3.3v vdimm jumper space from the Tforce is on my 6100-M9 as well, wo with a multimeter hooked up I tested the vdimm with bios set at 2.98v in bios and it read 2.94v. Fair enough. Then using a paper clip and tape to hold it I made a circuit between the 2 pins closest to the Memory slots in the place where the 3.3v jumper would be and voila !!! 3.28v Now all I have to do is make a bridge with conductive ink and I can really put my OCZ Gold VX PC3200 to work

BTW the location of the would be jumper is to the top left of the ATX power plug on the mobo. COnnect the 2 spots nearest the memory modules

Okay, I got impatient and made a solder bridge between the 2 points and I can now run my OCZ Gold VX PC3200 @ 2-2-2-5 1T at 454mhz as after my PSU heated up it now gets a steady 3.25v This is vs the 2-3-3-12 1T I was running it at before with the 2.94v

I'm glad you posted because I have a non-T 6100-M9 I plan to use in a build soon and was wondering if anyone has reported using the TForce 6100-939 BIOS on the 6100-M9? The boards are identical other than color scheme and upgraded capacitors.

A few weeks ago, before Biostar revamped its Taiwan website, I compared the latest BIOS for each model on the Taiwan website (the USA website often does not have the latest BIOS). The TForce model had a much newer BIOS available.

Since Biostar revamped its Taiwan site, all downloads (driver and BIOS) no longer reflect the actual build or release date, or are not listed at all. The build or release dates have been replaced with an 'upload' date, which was set when the database was recached or rebuilt last week for the new website.

e.g. all downloads for all models have an 'upload' date of 2007-05-31 or 2007-05-30

It won't work because things like audio codec , sata controller, and nic controller need to be identical , plus there are diferent resistors used to controll voltages. This would lead to very different actual voltages for components over what is set in the bios.

I have alreay looked into this :/

Like I said, the boards are identical except for some upgraded capacitors. The Northbridge, Southbridge, SATA, Audio Codec, LAN chip, LPC Super I/O, and PCB are all the same. There are also three extra MOSFETs implemented on the TForce for the CPU power supply, but that shouldn't make any difference to the BIOS.

I would be interested in what resistors, specifically, are different between the boards. I've certainly seen a BIOS used between boards with more potentially significant differences, including a different PCB layout and routing.

I have actually done this with the socket 754 versions, the Tforce6100 and Geforce6100-M7. Indeed here's what I wrote on the M7 including using the Tforce BIOS. If you're too lazy to read, here's the short version: Basically it worked (as in the board still worked) but anything that didn't exist in the Geforce BIOS seemed to not work in the Tforce BIOS. I got the same overclock and same lack of Smart Fan even though setting was there. Also, Vcore no longer worked.

Thanks! So you gained nothing, lost nothing, in all.

In order to put that bios bit to rest I flashed my 6100-M9 ( twice ) first with default Do not erase DMI then with erasing the DMI. BAsically lost Vcore adjustments ( as assumed would happen ) and most memory controll timings did not work. Plus it took me the better part of last night to get my floppy working again after the last flash so I could go back to my stock, depebdale and adjustable bios ( I started to get scared there for a sec @_@ )

So the answer is a definitave NO. You cannot flash the Geforce 6100-M9 to a Tforce 6100-M9 as I knew you couldn't because they "ARE NOT" the same thing minus beefier cap's. Those of you that think they are from looking at pic's need to realize all the tiny changes you can't see like diff resistors and vregs.

But in fact, you definitively proved otherwise. So you lost VCore adjustment. According to Zap's testing of the 6100-M9, the VCC adjustment was essentially not having any effect at all on the ability to overclock. What is the point of having a "working" VCC adjustment that does nothing, so you can tell your friends 'Looky here...I'm giving my CPU more voltage than default just because I can'?

The real issues are whether:

1. the board will POST and boot with the different BIOS
2. the board appears to work just as well with the different BIOS
3. no difference in performance

The answer is yes on all three accounts. Who cares about the "loss" of a function that did not "function" to begin with?
