adjusting the 3.3v rail has absolutely no bearing on your memory voltage adjustments in a bios that stops at 2.85v.

thats why when you set it to 2.7 its 2.7v +/- raising the rails to over 3.3v will not cause the vdimm voltages to raise. you'll only cause hardware failure as the board isnt designed to handle voltages that high.

the ONLY way this is possible is if you have a vdimm mod on your board and can adjust it via the mod.

not sure where you learned that adjusting the rails raises the vdimm thats just impossible.
if it were possible then why would there even be a voltage adjustment in the bios with a limit.

the limit set my MSI on this board as far as i know is 3.0v it may be 2.9though im still researching.

you guys who are modding these have tons more knowledge then i so you tell me an you adjust it via a bios mod ? of course going over the cap set in my the hardware voltage controller is impossible thats what a hardware mod is for but if the hardware limit is higher than what the bios actually is then you should be able to raise it.

The memory voltage is controlled with a resistor/ regulator conected to the +3.3 voltage line. Bios cant be moded to go above the maximum that the regulator will allow. People seem to think that the maximum setting on the regulator is 2.9 volts so thats the most you will get from the board without modding it.

You can do a 3.3 wire mod from the 3.3 line to the dimm but it involves cutting a trace on the motherboard and then you can control the voltage with the 3.3 rail like cd1986 was saying.

The easiest way is to use a ddr booster and it makes no sence to cut a trace in the board unless u are using 4 sticks of ram and have no space for the booster or you want more than 3.5 volts which i think is the maximum of the booster.

cd 1986 i just talked to :banana::banana::banana::banana::banana:breaker and he corrected me so i apologize,,, you are correct.

didnt think it would work since the hardware voltage controller locks what you tell it to in the bios but when you "trick it"

thanks for the heads up

Hey, can anyone mod a bios and add more "drive strength" options. i am hitting a huge wall because of TCCD + Venice mem controller. the "weak" setting is not weak enough.

Hi guys,

I took a new CPU today, 3200+ Venice 0519, it got rock solid till 2.7 GHz and 1.55v.

2.750 I tested with 1.6v but was kind of unstable.

So I wonder: there's anything I can try to get it stable at 2.750? (275x10)

My memory is at 166 divider, at ~ 230 MHz, 2.3.3.6. I tested at 2.3.2.6 and the memtested passed OK, but with this config the Windows don't boot. It hangs in the Welcome screen. Any ideas? Why the memtest approves it and the Windows don't?

Thanks a lot any answer,

AleX

Yes, I agree we need a bios with a weaker "weak" drive strg setting.

Can anyone send request to MSI about richer BIOS settings?

msi is not gunna do anything else with dram settings for this bios.

if you have read the forum over there some !@$!%^ retard has the balls to try and take MSI to court cuz he flashed his board with a beta bios and it killed his board.

not only is the thought rediculous but the forums have soooooo many warnings about using a beta bios and the correct way to flash that there is no way in hell that this guy can win he also would spend 100x's the amount to have this board rma'd or just replaced.

dont look to msi to continue to cater to overclocking. infact i wouldnt be surprised if they start pulling :banana::banana::banana::banana: like ASUS and severly limiting overclocking with horrible voltage and ram settings.

frankly this board has enough issues already with memory compatability and settings over 250mhz.

im already looking for a new board, nothing wrong with mine i just got used to my Lanparty 250GB UT when i had my clawhammer and nothing can compare to that... so..

asking msi for richer bios settings is just a mute point they arent gunna do it,, its hard enough to get them to release a bios that's even worth trying let alone one with more options.
i love MSI always have but their AMD64 line of boards really has some serious issues that they, years after their release still havent fixed

@Lestat

Good info, very well said. I feel like going to DFI nf4

me too, just ordered a DFI Ultra-D and a 9200SE PCI gfx card (omg, it is gonna roxor LOL)

but seriously, there is nothing wrong with my motherboard other than the lack of a weaker drive strength setting:(

Concur

Just waiting for DFI NF3 to sort out its issues

im am just trying to find the DFI 939 AGP board thats the best

i cant find it :(

and im such a freak for trading and stuff in the forums its gunna be hard to find. :(

anyone want a NEO2 plat and a gig of corsair pc3200 in trade for a GOOD DFI 939 board ? AGP version

great.. my raptor with my winxp just died on me..... no spare space or drive to install OS..... living now on ubuntu liveCD....... *sob.... aiiii just when i wanted to try the 1.9b6 BIOS...

anyway... superPI 1M runs 5 seconds faster on linux64... LOL...

Damn that sucks, i feel the pain. Never, I say ever try MSI's earliest BIOSes! especially v1.9 betas that are written from scratch

DFI AGP has more issues than the MSI. I was thinking about it to but i havnt seen any people who are able to get better overclocks with the dfi when they traded from the MSI.

We Can now add any memory timings we want to the bios by editing the bios so it doesnt matter if MSI add any more or not really. Voltages well the new venice san diegos dont like high voltage anyway and same with modern ram and a ddr booster works as well and is cheap.

The MSI is a very stable board im sure there are bad versions of it but i have a good one and its highly stable, voltages hardly fluctuate and the cpu clock is also highly stable you set 250fsb u get it dead on.

Raptors die all the time btw i doupt it was the motherboard to blame.

BTW NFM cd1986 made a 1.96 beta bios that removes the cpu temp reading and so will load setup. I had the same issue as you did and the bios works now that setting was removed. no temp bios

my board is great as long as i use a divider to keep my ram (Plat Rev 2's) at around 200mhz or less. if i go over then it craps out because the mem controller commands too much from them. the only way to counteract is via lower drive strength, which this board does not have:(

Try 133 3.9us tref setting it helps me a lot in any divider.

murdock has added several memory settings to his last round of bios's but be mindfull of the 196 beta he has.

if your 12v and or 3.3v lines are raised to high the system will not boot to any device.
it posts fine, it goes thru the whole process but when you try to boot to a floppy or cd or hard drive it says its gunna do it but nothing happens.
i had to lower my 3.3v line down to exactly 3.3v it was at 3.55v to raise my memory voltage more since 2.85v isnt enough for this OCZ PC4000 rev 2.
i spent 2 hours last night trying to figure out why it wouldnt boot. and finally on a whim dropped the 3.3v and 12v back to stock rails and she booted fine. i thought for sure i had lost my mobo.

another thing i saw was that it was saying that the -12v was only 7v this could have also been it but it didnt boot to the floppy so i could reflash with NFM bios until i lowered the 3.3v line

If the extra memory options can me enabled all i can tell modders is grab a stock DFI bois from the NF3 250GB and explore that and see how they have it layed out and then implement them into the MSI bios.

this needs to be done. it might be a good board but modding only certain aspects of the memory timings isnt enough you need to explore all options each setting is effected by the others so to change one many times in higher overclocks you need to change others also.

i just cant figure out why my system isnt stable past 255mhz no matter what voltage, no matter what multiplier and no matter what divider.

only thing i can think of is a faulty mem controller on the cpu itself and if thats the case man-o-man im gunna be pissed.

Very well said, I had NF4 in mind. I PMed tictac about NIC hacking, he didn't answer :( I wanted to hack Realtek Gigalan, make it disabled by default, and add to it 5.0ns read preamble tref etc, so they can be anbled when you reach high htt, because with default 200 they wouldn't boot

I get a reading of 7 volts on the -12 volt line as well. I think that its just broken :)

I get the same 7votl reading on the -12 volt line.

How many tref values do we have access to on this board, maybe we can have a vote to see which ones are the most common and then have bios made with them on all dividers. I read tref has a big impact on stablility.

for me 200 3.9us (a64 tweaker setting) Actually i think its 7.8us really is the best 1:1. 133 3.9us is the best with any of the other dividers.

Athlon 64 tweaker is wrong when it says 3.9 it really is 7.8us you can check with rmma. Cd1986 and i did some testing on it look back a few pages.

Well can the people that are doing the bios modded check to see which tref values they can implement into the bios and then drops them here and I'll test with what we can use. and hopefully other will to.
