945P Platinum, memory divider (BIOS)

First I want to say hello to all users!
I recently bought MSI 945P Platinum motherboard with Bios v1.3, CPU is Intel Celeron 2.66GHz, 64bit, LGA775, 256mb cache which I intend to replace with some Pentium D in about a month. But until than I tried to overclock CPU but all I achieved is 145*20=2.9GHz (default is 133*20=2.66GHz) Vcore 1.4v, with Kingston VR DDR2 533MHz memory. The thing is that FSB:DRAM is always 1:2, how can I change this in bios? I think that the problem is memory, it wont go more than 580MHz... and if I put FSB at 146 the only solution is CLEAR CMOS.
I didn`t tried with different bios versions because there are no other versions to download from msi.com.tw.
P.S. I also tried to set in bios>core cell>memory manual 4-4-4-11 533MHz but nothing happens, I cant change FSB:DRAM from 1:2.
Please help.
Thanks in advance.

You can.
The o/c method goes like this: Every 1 FSB rised = 2 RAM MHz rised. If your 2.66GHz Celeron is 133 x 20, 133 is the FSB and 20 is the multiplier so your RAMs will be 266 x 2, where 266 is the RAM speed and Double Data Rate 266 will give approx. 533MHz. We'll only take the FSB and the RAM speed here for divider calculation.
133 : 266 will ratio as 1 : 2. If you want to o/c higher in terms of CPU speed, you can try dropping your RAM speed to 200MHz and rising the FSB to higher clock speed. This will allow the RAM speed to increase as well.

945P Platinum No Manual Bios Download

Anyone help why MSI took off Manual Bios Downloads for 945P Platinum Version Boards
I like to Manual Update Board Bios to latest Bios before Loading OS and view current Version releases (without LiveUpdate)
Also anyone experienced Microphone Problems plugging into Mic Plug (Onboard Realtek 882) all version Sound Drivers
Low Voice pick up (Skype or Sound Recorder) have to use USB Mic
Have tested on 10 Different Boards and differnet plug in mics all the same

Not unusual that bios is removed / greyouted, when there are just the original 1.0 bios and no update versions.
Have you been able to download newer/later biosversions then the orginial bios before ?
No clue about the mic-port issue.
Sometimes separate pci soundcards gives better functionality.

945P Platinum IDE 2 & IDE 3 works in PIO MODE?

Hello there, I just Bought MSI 945P Platinum M/B and Intel Pentium 4 D @2,8Ghz with 1Ghz RAM, 80GB SATA2, 4 CDRW drives (PATA) where 2 of them I plug in to IDE1 slot(known as RAID, but i configured it to IDE function in BIOS) and the others are in IDE2 slot. I used winxp with the all M/B driver installed, everything's seems ok in device manager, the problem is when I use nero for burning with multiple recorder activated, the windows then going extremely slow in any response even with the mouse movement that it seems windows is running out of system memory. Then I check the device manager and I found that IDE2 run in PIO Mode, IDE1 run in UDMA Mode2.
It didn't make any changes when I used IDE3 slot, it run in PIO MODE either.
How Can I configured The IDE2 & IDE3 to works in DMA mode? I've try any combination in BIOS Setup... it didn't work??
HELP, any advice would be appreciated THX...

PCI Bus Mastering already enabled since the 1st time I configured the bios, I'm using 2 pieces thermaltake IDE round Cable that plugged in to IDE 2 & 3, IDE 1 using cable that came with the board. I'm using 4 LiteOn PATA Writers and Seagate 80Gb SATA2 HDD plugged in SATA1 port.
1st configuration, 2 writers are in IDE 1 & the others are in IDE 2
2nd configuration, 2 writers are in IDE 1 & the others are in IDE 3
3rd configuration, 2 writers are in IDE 2 & the others are in IDE 3
All above configuration make the same result, IDE 2 & 3 Won't run in DMA mode
I've try to switch the thermaltake cable to IDE1 and it's work fine (DMA still on).
It doesn' t matter how I configured the BIOS (SATA to combine, enhanced, or AUTO) IDE2&3 still in PIO Mode.

Problem overclocking my 945P PLATINUM+805D

hi...
my english is lack so i'll make it slow
i just bought the msi 945p platinum with intel dual 805d.
unfortunally, i cant o/c the system ..
the bios got no update on msi website so i see it is the latest bios .
i know that the 805d can be o/c to 3.2 without any over voltage ...as concidered to other motherboards .just by increasing the fsb to 166.
i am kind of newbie in the terms of o/c .
i tried to make some adjustments in the corecenter software but the system freezes or get quickly unstable.
i cant make the fsb on bios ,higher then 165 .default is 133 by the range.
i put over voltage to the memory ->1.9v .default is 1.8 , and put the fsb to 165...but the system didnt post .
anyone here can help me please ?

I also have a D805 and an 945P platinum.
In fact i manage a 3.3 GHZ stable overclock by using these:
In BIOS cell menu:
CPU ratio unlock-unlock
Memory function sub-menu - Enter, then
DRAM timing - AUTO (!!!!)
System memory frequency - auto
D.O.T.3 Step0 setting - disabled
Auto Detect PCI clock - Enabled
Spread Spectrum - Disabled
CPU fsb frequency - 165 (THIS IS THE MAX THAT MOBO PERMITS AND IT PISSES ME OFF)
PCI-e frequency - 115
CPU voltage - 1.21V (1 step up from normal)
Memory voltage - 1.8V
AGP/PCI voltage - 1.5V
I have to say that i use a ZALMAN 9550 heatsink and a pair of OCZ DDR2/667 dual channel. CPU temp as BIOS shows is 42C
Also, memory is not overclocked at all !!!
PSU is a TAGAN 500W
I am sure that i could go up to 3.6-3.8 GHZ with a board that is more "overclocking" oriented.....
But alas...i have no other problems (so far) from it

Nearly perfect FIX For Memory Divider Problem !

Hi folks, as we all know there are some overclocking issues with the K8N NEO2 Platinum, but one of them seems to be fixed.
For all those peaple that had problems to overclock with an memory divider active ( 200=1:1 166=5:6 133=2:3 100=1:2 )
and problems showing, that they could not use high memory clock frequencies when using another divider then 1:1 !!!
Try following: use A64Tweaker ver.0.31 final ( bugfree I think ) and set the TRFC value from probably 12 to 14 or higher.
NOW YOU CAN OVERCLOCK THE MEMORY LIKE BEING IN 1:1 MODE.
Not the perfect fix, because it is not applied in BIOS but perhaps someone like SYAR2003 could change this default value in some MODDED BIOS?????

I have a MSI K9A2 Platinum Motherboard. Bios version 1.8 overclocking

I have a MSI K9A2 Platinum Motherboard. Bios version 1.8
AMD Phenom II X4 940 3.0 GHZ that I have over clocked to (17.5) 3.4Ghz
However anytime I go over that to say multiplyer set to 18 (3.5 ghz) it still runs but crashes when running high end games. I know I have to go in an adjust voltages. However, in the cell menu I can't access the CPU voltage areas I hit enter but nothing happens. It tells me Grey is defualt, White is stable and red is the obvious not recommended setting, but again I can't access it. Is there something I need to disable before I mess with the voltages?
I know that doing any of this could fry the chip I have liquid cooling pretty much this idles at 28 deg Celcuis, that is with it over clocked so I know I have som room and know I should only up the vltage slightly. I just need to know how to do it.
I also wanted to adjust the FSB from the current 200 to 270 which I was told is possible with this board and also that is where it should run stable. Again I just need to know how to access these things in the Bios. If its a bios issue I can update to the next one,1.9, but did not see the need to do so. Anyways any help is greatly appreciated. I am familar with overclocking just not with this motherboard. Any user who uses MSI who could offer assitance would be greatly appreciated. Thanks.

945P Platinum and Pentium D 945

Did anyone try Intel Pentium D 945 CPU on the 945P Platinum motherboard? Does it work with bios 1.6?

Quote from: Maesus on 09-March-07, 19:50:58
oh well, there is no good reason why D 945 is not supported by 945P. Just make sure you have the latest BIOS.
Once I've seen OK on the CPU Support Page for the Pentium D 915.. Maesus do you think I should try? ???

Intel Core 2 Quad Q8400 to 945P Platinum?

Hi, i have question.Is possible aplicate processor Q8400 to motherboard 945P platinum?I downloaded the newest BIOS file W7176IMS.230 for 945P platinum, but i didnt find cpu support.Thx a lot.

>>Posting Guide<<
Your specific processor does not appear on the CPU support list.
http://us.msi.com/index.php?func=prodcpusupport&maincat_no=1&prod_no=193#menu
Suggest you contact >>How to contact MSI.<< MSI technical to check if there is any intention to do this. I doubt that they would do any further work on a BIOS on a discontinued MB.

945P Platinum With The MSI NX7950GX2-T2D1GE

Hey guys,
Ill be receaving one of these cards shortly, though since ive been out of the whole PC loop for a while now, i only just noticed that on certain motherboards support this card.
On the list from Nvidia website it states the "945P NEO2-F" as compatible. Though from what i can see, there is no real difference between this board and my "945P Platinum". I know the main issue seems to be 16x PCI Slot, and the bios, so before i receave card, could someone please confirm that this card will work with my motherboard =D hopefully before i receave it as i can still change the card .
Thanks in advance,
David.

Just want to point out too people that the g-card does not accutaly fit into the motherboard -_-, there are two capacitor's near the sata ports that are in the way. Though a bit of electrical tape and removing the bottom bar off the card and it just fits in.
Also it is working atm, though for some reason am getting rather low scores in 3d-mark06. Scoring around 5.5k when most people even with lower spec'ed systems seem to be scorring in the 8-10k's
Might just be my setup, but who knows.

I'd like to know if maybe theres something wrong that I'm doing or if both sticks happen to be bad or something else that I'm missing? I've tried different combinations of slots/sticks and tried manually setting the fsb with the JB1 and JB2 jumpers. Someone said the 1.3 bios was picky about ram but I'm not sure how to check what bios version it is since I cant get that far =p

K8N Neo4 platinum edition v1 (bios W7125NMS V1.6 062305) -- after POST stucked

hi i'm runningan athlon 3000+ in K8N Neo4 platinum edition v1 (bios W7125NMS V1.6 062305) and i have a very like problem:
today i tried to install freebsd(install started fine, nothing went wrong, i repartioned my hdd and the installer started),
for some reason i had to abort the installation process. since then i can not boot in from any device(cd,usb the hdd is in a
half way to bsd install state so it's not an option atm).
the post screen comes up and i can interact with it in a way(i can press tab and it drops me
to the detailed post screen,ctrl-alt-del also works i can restart with it), but i neither can enter to the BIOS setup /DEL/ nor the boot menu /F11/.
i've tried reseting bios settings by flushing cmos(removed the battery,pressed SW1. something must happened because the post now checks for sata devices
and the graphical screen/that one u can bypass by pressing TAB/ was not presented before).
it also detects my hdd and my cd-rom too. but still nothing happens after the POST.
others said updating my bios would help. but still there is no option to boot from.
if i am doing wrong something please let me know,
thank you for your help
Andrew

the solution:
disable ide1/slave when the broken hdd is not connected and bios accessible; poweroff; reconnect the broken hdd to the PC;poweron; boot from a linux livecd; gpart/fdisk/something to repair the broken hdd;be happy life is nice
the trick was that bios and post is not messing with the broken hdd(while it was blocked in the bios)
so i could boot with a live cd when my hdd was connected to the PC.
since linux trixx out bios i was abel to interact with the post_killer_hdd (even it was blocked in the bios).
i hope somebody will be able to use it one day if something is not understandable drop me a PM.
problem solved im installing the os to the hdd,topic is SOLVED.
maybe the other guy who has some similar issues with his config/hdd could use this post too.
regards,

785GM-P45 with 1GB dedicated video memory in bios

has anyone able to allocate 1GB for dedicated video memory in bios and has at least 8GB of RAM. i had already updated the bios to version 11.8, with any 3 sticks of kingston 2GB RAM I can allocate 1GB for video memory in the bios, but the minute that i have the 4th stick install, the pc will not complete boot into windows. with only 3 sticks, it doesn't matter which memory slot is open, it will boot into windows and shows 1GB dedicated video memory. all the RAM tested fine with remtest. with all 4 stick install it will only boot into windows with 512mb dedicated video memory. thanks in advance.

945P Platinum (MS-7176) D-Bracket Connector

I've just installed a 945P Platinum. Upon installing the D-Bracket, I noticed that the connector to JDB1 is not keyed the same as the JDB1 pins on the motherboard - and thus will not connect. On the motherboard, there is no pin at pin 9 on JDB1, however on the D-Bracket cable connector the "key" (blocked pin) is on pin 10 - and therefore the connector will not fit.
Have I gone nuts or has anyone else seen this issue? Thanks!

Yes, I'm looking at the one labeled JDB1 - and it looks just like that manual says it should look - with no pin at pin 9.
To me, the problem is the connector from the D-Bracket - where is has pin 10 blocked instead of pin 9. Since there is a pin 10 on JDB1, it's impossible to connect. I thought I was nuts and looking at the wrong thing.
Any ideas - or maybe I just have a bad D-Bracket?
Thanks for the reply!

Cool and Quiet problem on K8N Neo2 Platinum v1.3 bios

Hello
I have a problem with the Cool and Quiet feature on the K8N Neo2 Platinum (v1.3 bios).
As soon and I boot the Core Center v1.7.0.0 will instantly overclock my A64 3500+ CPU to 3000+ Mhz. Of course this reboots my PC.
I have Cool and Quiet enabled in the bios, Automatic overclocking disabled in the bios and the Core Center softwares overclocking is (well it was) disabled? How can I install it or get it to stop overclocking the system.
I want to run the Core Center to enable the Cool and Quiet fan controlling stuff.
Thanks

Strange that Corecenter would overclock your cpu to 3ghz. It's known to be unreliable software, but not that unreliable.
Are you running a stock 3500+, or are you overclocking the HTT/FSB beyond 200?
Previous posted was right about cool and quiet software. You don't need corecenter to run it. Just stay away from corecenter and even uninstall it
Cool and quiet software (a device driver that you download from AMD, or that comes pre-installed with XP SP2) simply works as follows. It introduces the notion of several p-states (processor states) that it switches between based on its reading of cpu load. A p-state is a pairing of cpu voltage and cpu multiplier. On my 3200+ newcastle, the p-states are:
1.5V, 11x
1.4V, 10x
1.3V, 9x
1.1V, 5x
Your 3500+ might be similar. Anyway, just run cpu-z instead of corecenter to watch your cpu speed changing on the fly.
As far as fan speeds go: the cool and quiet driver doesn't affect fan speeds. That means to get the "quiet" part of "cool and quiet" you need either
(a) a fan that has a temperature sensor and which automatically changes its speed based on that, or
(b) just use the motherboard BIOS setting to do the same via bios software.
(c) use speedfan to do the same via windows software.
I myself prefer (b) but it depends on the bios accurately reporting temperature, which can vary wildly between bios releases (e.g. newcastles didn't start getting accurate temp reports until bios 1.4).
