New P45 Platinum build complete!

I got my new system put together last night.
MSI P45 Platinum
Core 2 Duo E8500 Wolfdale 3.16GHz
EVGA GTX 260
Kingwin 700 w PSU
WD 10,000 rpm OS drive
X-fi Sound card
Zalman 9900 CPU cooler
Four gigs DDR2 8500 1066 RAM
It started right up, and lit up like a Christmas tree. The bios set some funky RAM timings, so I went ahead and manually set the timings, speed and voltage. I'm running the RAM with what's advertised on the side of the sticks. 1066/2.1v/ 5 5 5 15. I have touched them while the PC is running, and they seem to stay pretty cool. If I run into issues, I will set them to 800 and less voltage. I got Vista 64 installed fine, and am setting up the OS to my liking.
So far the board seems pretty solid. I do notice when I reboot, that I hear a fan/fans throttle back on the RPM, and throttle back up afterward. I will have to look around in the bios some more and see what I can do about that. The instruction book for this board is pretty limited. My other MSI book for my older mobo is allot more informative.
I do notice that both my CPU cores seem to be stuck at 27C. The actual CPU temp fluctuates fine with CPU usage, but the cores don't budge. I read that this is pretty common with these Wolfdales. My brothers build was the same way. I could get them to move if I ran Orthos for awhile. No biggie.
Anyway, I wanted to thank you guys for helping me select my new MSI mobo. I'm sure I will have some questions since this hand book is so limited.

keizer, good to hear some good news. when you have, would you please take a few shot of your bios cell menu for your ddr2 1066 setting [all of them if you can] so others can follow.cheers
Well, I think I still have some tweaking to do. I'm having a little trouble on cold boots. Before I manually set up my RAM, I left everything at default. It was running at 1066, but didn't have the right timings. With the default settings, it froze at the Microsoft screen with the little green progress bar. I did a hard reboot, and everything was fine, including all the reboots I did while installing software.
Anyway, after setting up the RAM manually to 1066/2.1v/ 5 5 5 15, I shut the system down and drove into town for a few hours. When I came back, I turned my system on again. It made it past the screen where you can press delete to enter the bios, but just sat there with a black screen after that. I did another hard reboot, and it booted into windows fine.
Any ideas what would cause this? Maybe it doesn't like my RAM settings. I may have to try them at 1.8v/800/5 5 5 18
Also, I wonder if this could be a bios issue? My board came with 1.2 bios.

New to the P45 Platinum

Whew. That was a long day of trials and error for me to set up the motherboard. I feel really accomplished saying I put together my own computer for the first time.
The story so far: Windows is loading okay, but ONLY on 1 stick of ram in slot 1, and ONLY one HDD. When I try to reboot with 2 sticks of ram, Windows freezes at the loading screen. Same for when I try to plug in my 2nd HDD.
So any BIOS numbers that I have to edit? Is this a problem outside of BIOS and in Windows itself?

Well I flashed to 1.5 a few days ago. And I've decided I'm going to give my old computer to my best friend (although I'd have to put everything back together.) Since my current heatsink (Arctic Cooling Freezer 7) works better on my old P6N-SLI, I thought I'd throw that on too. Can anyone recommend me a heatsink that'll fit nicely into my new P45 Platinum? The weird DrMOS pipes kinda get in the way (and are actually getting scratched up by the Freezer 7 right now).
Quick responses are always appreciated. My Newegg order of an Antec 900 case is being processed now, so it'd be nice to add to it before it ships out.
Maybe one of these?:

Add a new 4tb hdd to msi p45 platinum ?

I'm planning to add a new 4TB western digital, caviar green HDD's for my msi p45 platinum motherboard ist work will or use 3 tb .
thank you

Just some notes regarding large drives on the older chipset boards.
The P45 Plat has
• SATAII controller integrated in ICH10R/JMicron® 363 chipset
- Up to 3Gb/s transfer speed.
- Supports six SATAII ports by ICH10R
- Supports two SATAII ports by JMicron 363, support SATA RAID 0/1/JBOD.
In principle the ICH10R allows amongst Raid capability also the ability(potentially) to handle up to 2TB in AHCI.
What other users with similar boards have however commented on is that they were able to use up to 3TB drives on the JMicron controller, obviously with the latest firmware for that controller and also AHCI. We all know that the JMicron ports are a bit slower than the Intel ports, but that is evident with Asmedia as well.
So when you do test, check both your Intel and JMicron ports and see what they report as the drive capacity in the BIOS.

New K8N NEO4 Platinum build. BIOS recommendations?

I am building a new NEO4 Platinum box. The MB currently has the version 1.1 BIOS. I thought I might flash a newer BIOS before starting my OS install. Any recommendations on the most stable/functional BIOS version as a starting point? I see 1.5 is officialyl out, but have run across a 1.71 Beta.

That's great
As you have a Winnie there's no urgent need to update your bios. it's entirely up to you.

Unstable P45 Platinum!

Hi all this is my first post and i'm hoping someone can help!
I recently purchased an MSI P45 Platinum board (P45 Zilent pack) so that i could move away from my "upgrade limited" Dell PC. I also bought a new case and have used all the parts from my Dell PC with the P45 Platinum board in the new case. After doing this i now find my PC to be quite unreliable... i've left everything set to "auto" in the bios cell menu and have re-installed Windows 7 64-bit and all the latest drivers for the new motherboard.
The majority of games i try to run will just hang on the main menu! Windows 7 has also crashed a couple of times giving me a blank/black screen whilst emitting a loud buzzing sound from the speakers! The only thing that is different from my old PC is the motherboard and the case, everything else is the same and i had no issues before aprt from the fact it was a Dell !
Here are my PC specs (nothing special):
MSI P45 Platinum motherboard
Intel Core 2 Duo E6850 @ 3.00ghz
4gb Corsair XMS2 CM2X2048-6400C5 DDR2 800mhz RAM (2x2gb dual channel 5-5-5-18)
500gb Western Digital SATA hard drive
2 x Powercolor ATI Radeon 4850 graphics in Crossfire (1gb each)
Hitachi/LG DVDRW/CDRW combo drive
USB internal multi-card reader
850W Cooler Master Real Power Pro PSU
I have updated the motherboards bios to v1.6. I have also noticed my USB card reader light stays on all the time... even when the PC is switched off?! Everything is connected correctly to the motherboard and i even plugged a cable into that badly positioned 4-pin molex PCI-E power connector (JPWI) - Do i still need to do that considering each GPU has it's own power connector and my mainboard connector is the 24-pin type?
One other thing i noticed are the incorrect memory voltages displayed in the "dual core" software - it reads 1.950V when my Corsair memory states 1.8V on the package, I even have all this set to "auto" in the bios.
Anyway sorry for the long post but i would appreciate some help with this, thanks

Quote from: blazing storm on 13-February-10, 22:16:57
First of all, try with just one graphics card and see if that makes a difference.
If you've set the RAM voltage to auto then the motherboard decides what to set it to. You need to go and set it to 1.8V manually. Whilst you're there set the RAM timings manually to the specified 5-5-5-18 2T.
Thanks for the reply and advice! I done a complete re-build of the system and checked for any loose connections etc... I have also just installed 1 of the ATI cards instead of 2 but the system still remains flaky! I did as you suggested and manually set the RAM to 5-5-5-18 timings but i cannot find the option to adjust the command rate between 1T and 2T... it just does not exist in this motherboards bios. Also i cannot change any of the RAM voltages... or any other voltage for that matter as it's all greyed out in the bios??
MSI's "Dual Core Center" utilty is still displaying the wrong RAM voltages as 1.930V this time (although it highlights 1.800V in green when i click the voltage drop down menu.... so why does it not use 1.800V by default???). Any help is always appreciated, thanks
I was going to upload some bios pics but it seems this cannot be done.

P45 Platinum - Vista works just fine, but unable to get into BIOS

This is my first build, so I'm still learning a lot. Be kind!
I'm using the P45 Platinum with an Intel Core 2 Duo 3.0ghz Wolfdale cpu, 2 2gb sticks 1066mhz G-Skill ram, a Corsair 750w PSU, EVGA Nvidia 8800GTS video card, a 74gb WD Raptor HDD and a 250gb WD Caviar HDD (both SATA). I'm currently running 32bit Vista until 64bit has more support.
I have never been able to access the BIOS - before Vista was installed the splash screen was too fast so I kept missing my oppurtunity to enter BIOS, so I went ahead and put in the Vista install DVD. It installed just fine - it doesn't see my second HDD, but I expected that due to it being SATA.
I want to enter the BIOS to disable the audio so I can download the new Realtek audio drivers (I have no sound, even after installing the driver off the CD), but when I start up the computer and hit DEL (when prompted), it takes me to the Windows Boot Manager. Several times I have repeated the process and every time it takes me to the boot manager instead of the BIOS. The BIOS is obviously working, I just can't access it.
Any help is appreciated.

Simply keep hitting >DEL< as soon as the Splash screen appears. If that doesn't help, clear CMOS with main A/C power cable removed from PSU. Upon restart the system should hold with a CMOS Checksum error and give you the chance to hit F1 to enter BIOS Setup. Now you can load "Optimized Defaults" and disable the BOOT LOGO.

Problems Powering up MSI P45 Platinum board

I've currently started a new build using the following equipment:
Coolermaster COSMOS 1000
MSI P45 Platinum
Intel Quad Q9550 Processor
2 x 2gb OCZ Memory
Sapphire ATI 4790 HD 1gb Graphics Card
PC Cooling 750W Silencer PSU
Wired everything up, connected all the connectors. When I go to power up the system, I get a Red LED 3 but no fans or anything spins up. Switched out for a known good power supply and received the same problem. Not sure where to go from here?

Hi,
take the board out of the case to test it on a non-conducting surface in barebone configuration (CPU, one memory stick, video card, Keyboard and power connectors, nothing else). Make sure every kind of connection (front panel etc. to the case is removed).
Then clear CMOS with main A/C power cable removed from PSU and try to power-Up the board. Try both of the following methods to power-up the system:
1. use the little red onboard-power-on-button (make sure you don't confuse it with the reset button)
2. shorten the two pins of the board's pin header that are usually hooked up to the case's power-on button with a screwdriver

Quote from: flink on 30-April-09, 13:56:54
i'm sure the hole for the cmos clear button in the i/o shield is the problem. the button is pressed by the i/o shield and your pc won't start.
a well known problem.
I remember reading about this issue before I built my P45 Platinum system. I made sure during the build that the button was not being pressed by the i/o shield.

Msi p45 platinum power up problems

Hey guys, i have got a fairly new system i think its about 2 months old
e8400 e0
msi p45 platinum bios 1.71beta
4g kit 1066 kingston hyperx
palit 1g 4870
huntkey 650w psu
Okay so heres the deal, the computer was running at 3.6ghz, stable for the past 2 months.
I have tried 4ghz with almost every possible combination of volts, but it passed prime 95 for about 36 hours 1 day, and the next have a random reboot
I also noticed that my psu was making this weird whining noise so i just ordered and installed a pc power and cooling 750w.
To my happyness comp booted up at 4ghz and seemd stable enough for 2 hours. (just searching net and stuff) then boom, comp turns off.
okay so i thought maybe it wasnt stable. tried to reboot but to no avail. all i get is about half a second when my fans try to spin up but then it just cuts off again.
i have tested the usual out of box, 1 stick of mem, clear cmos with power cord removed, removed battery for 10 minutes but nothing. Also did the same with the old psu which was working.
All that happends is it trys to start, eg leds everywhere flicker and i mean flicker there is no way i can see what order. Im refering to the 8 leds down the bottom. the flick on then off.
After trying to start it up once, i wont get another chance to start it. eg i have to remove the power and wait till the power is completly gone from the system b4 i can try again and only have the same thing happen.
Thanks for your help guys

Something may have been damaged during overclocking. What voltages did you work on when you overclocked the system to ~4GHZ? What where your temperatures?

Next, I see that you are using a Beta BIOS, what's the reason behind it?
I suppose the reason is this:

P45 Platinum Posting Issue

I have a P45 Platinum Motherboard that I purchased from Newegg on the 14th. I recieved it on the 17th and built a brand new system with it from scratch. I'm using an intel E8400 Wolfdale CPU along with 4 sticks of 2GB G-SKILL DDR2 RAM (PC-8500) @ 1066. I'm currently using a BFG 8600 GT graphics card (soon to be a Sapphire 3870x2) and its all being powered up by a Rosewill PSU with 850 watts of power. All items purchased from Newegg (aside from the 8600gt, thats an old card).
Here is whats frustrating me, and as you can see from the topic's title... my system doesnt post... sort of.
Technically it does POST however it will only POST if i hit the "Clear CMOS" button located on the back of the system. Upon doing so, the system will act as though its booting up for the very first time. It will ask you to set up your CMOS configurations and once that is complete it will load up Vista right off my Harddrive with no problems.
However..
Once the system is shutdown or restarted, the system WILL NOT POST and I am forced to clear the CMOS again!
Now... I have troubleshooted ALOT with this board... and I'm left with only two conclusions... either this board is defective (highly likely) or it just needs its BIOS updated.
Ram sticks, video card, HDD, DVD drives... all have nothing to do with it! I can remove all devices and turn the system on with no memory sticks, and I will be left with 4 solid red lights (the ones that turn green after posting) and there will be no beeps of any kind to indicate I dont have memory installed. However... once i hit the clear cmos button then it will post and it will correctly see that there is no memory sticks... it will beep.. I will shut down... I will install devices... turn it on and it will POST.
It appears it can complete the initial POST without issue, its POSTING for a second or a third time thereafter that becomes the issue...
I need help with this in a desperate way...

So okay, heres whats bugging me in regards to my memory sticks. Your throwing out numbers like PC2-6400 but on the stick it says PC2-8500?
So... is it incorrect or what?
Let me try to explain a little more detailed:
A given board/BIOS is not able to read the sticker that is glued to your modules but only the SPD Profiles that are pre-programmed into the SPD Chips of your sticks. If you check those SPD-Tables with Everest, Memset 3.5 or Memory-Z (in BIOS) you can see for yourself that the "fastest" Profile is a JEDEC-Standard DDR2-800-Profile [CL5 @1.8V]. There is no profile for DDR2-1066 clock speed. That is why whatever Board or BIOS you try, your modules will be detected and handled as DDR2-800 (PC2-6400) modules. It is evident, that there is no issue here and there is no point in discussing this any further.
So, what does the PC2-8500 rating mean? It means, that G.Skill has tested these modules, which are essentially DDR2-800 sticks, up to DDR2-1066 clock speed with increased voltage. Basically, G.Skill is giving you a permission to overclock these memory sticks by increasing the voltage above the 1.8V +/- 0.1V JEDEC-DDR2-standard without voiding your warranty. Therefore they sell these modules as DDR2-1066 RAM.
If your RAM was "real" DDR2-1066 memory, it would have to be able to operate @1.8V (DDR2 standard voltage) above 1000 MHz. But in order to be to that the timings your timings would have to be relaxed to CL6 or CL7 depending on the chips used by the manufacturer. In addition to that, there needs to be an SPD-Profile that tells the BIOS that these modules are DDR2-1066 and that it should set frequency, timings and voltage accordingly.
Furthermore, the P45 Memory Controller does not natively support DDR2-1066 modules. That is why that rating is tagged with an "OC"-mark on the product page of the P45 Platinum.
This said, your only option to get these modules to DDR2-1066 speed is to manually set the clock speed and increase DRAM voltage in BIOS. There is no other way to get there and it is also perfectly normal to do that.
Now, let's look at your actual problem: The system is unstable as soon as you want to overclock your RAM to the DDR2-1066 rating, that G.Skill has promised you.
There are a couple of reasons that can cause such an instability:
1. Your memory modules are not up to the task of running at that speed.
2. Your memory related BIOS settings (especially timing & voltage) are not properly set.
3. The board is incapable of supporting such clock speeds above chipset specifications (remember: DDR2-800 max. according to Intel).
4. The board's current BIOS is not optimized in such a way, that it can properly handle DDR2-1066 clock speed.
I can assure you, that the board has no problems with DDR2-1066 in generell and I suspect that this is simply a BIOS related problem. I have no issues getting my Kingston HyperX RAM to DDR2-1066 speed with BIOS v1.1b5.

I am still using the v1.0 Bios. I've already stated that I don't feel comfortable flashing my BIOS with something thats in Beta.
Of course, I can understand that and it is generally not a bad idea to be careful with BETA releases. However, in your case I believe the problem is rather BIOS related. I had stability problems with DDR2-1066 clock speed with different earlier BIOS Versions as well (including v1.0) and I have tested more than 10 BETA- and Performance releaes so far. BIOS v1.1b5 however allows stable operation @DDR2-1066 MHz.
If you do not want to use flash this BETA, you will have to wait for an official release which can be expected soon. This official release will be based on v1.1b5 and it could very well be the case, that v1.1b5 will simply be renamed to v1.10 and offered for download on the product page.
Quote
And as I remember it, it supposedly voids your warranty if used??
You can contact MSI Technical Support and describe your problem there as well. I am almost sure that they will provide you with a more recent BETA BIOS in return (v1.1b5 or later). If you want to be reassured by an official feedback from MSI Support, I suggest you contact them and see what they have to say.

P45 Platinum hang @ power up

Hi,
my p45 platinum wont boot to BIOS. It gets stuck at Memory Detection Test. Cold boot gets it sometimes to "Decompressing BIOS image to RAM for fast booting.".
I'm not getting any feed to my screen.
My build:
Intel Core 2 Duo E8400 (older rev)
MSI P45 Platinum (BIOS v1.6)
2x Mushkin enhanced XP2-8500 2GB
2x Club3D radeon HD 5770
Thermaltake Toughpower 750w cable management
I've tried the following:
1. cleared cmos (many times)
2. switch the places of the memory sticks and also tried with one only
3. uninstalled the whole build and then re-installed it (including cpu)
4. bareboned the build (only cpu, video card and memory sticks installed)
5. switched the video card (got 2 identical)
6. tried even without the memory sticks
The problem is similar to what happened 2 years ago. Back then I sent the MOBO for a warranty service and it came back with a note "No problems found". I also ordered new memory sticks and they didnt help.
After 2 months of being powered off, the problem just vanished without a trace of what might've happened..
The problem came back after this:
I was uninstalling usb device drivers on Win7Pro, and I had to restart the computer because i accidentally uninstalled the mouse and keyboard and Windows wouldnt re-install them even when I changed the usb port of the forementioned devices. After restarting, the motherboard just got stuck with the 4 leds on (which indicates that the processor is damaged or not installed properly). After powering off the computer, I turned it back on, and then the motherboard got stuck to the "Memory Detection Test" phase..

P45 Platinum - OCing with FSB jumpers

Hi,
I have already had problems with my memory and you guys helped me alot so i suggested to post my new problem here,,, maybe you guys know what to do.
I have a MSI P45 platinum with Intel Q9550 but when i check the ratings with CPU-Z it says my CPU is running at 2 GHZ and only using 6.0 x multiplier... were it should be 2.83 GHZ and 8.5 x multipliere ( Stock settings ).. how is this possible and how to fix this ? also in the BIOS it says its just running normal ( 2.83 GHZ at 8.5 x ) and so thoes windows XP and vista do ( they show 2.83 GHZ. ) but i think that is normal since vista and XP see a Q9550 and tell me it runs on 2.83 GHZ when its working properly.
it is running on 1333 MHZ ( well its 1336.4 to be exact) but i think it won't hurt if its running on it right ?
what settings should i change to let it run normal ? maybe the voltage for the CPU ?
Also i was checking my BIOS for this problem but i couldn't find he multiplier option where you can OC it... or do i need to enable something for it ?
Thanks for everyone's time and wisdom

Quote
so i guess its ok...
Definately!
Quote
Also where can i change the multiplier in BIOS for overclock ?
You need an Intel Extreme Edition Processor to be able to overclock the CPU by rasing the multiplier beyond standard. On all other model, all ratio higher than default are locked by Intel.
Quote
or should I raise the FSB bus speed a little higher.. what do you suggest ?
Raising the FSB Clock Speed is the only way to overclock the processor. You can try to remove the OC Jumpers of the board completely, which will force the FSB Frequency to 400 MHz via hardware. Do a CMOS Clear (with main A/C power cable removed from PSU) after removing the jumpers and see if the system will start up okay. Alternatively, you can simply raise the FSB Clock Speed in BIOS (but keep the FSB/DRAM Ratio in mind, when you do that, as the memory clock is tied to the FSB Clock via set ratios.)

PROBLEM RESOLVED: SATA RAID Vista x64 Driver Errors on P45 Platinum

I have installed 5 WD 640GB SATA drives on my P45 Platinum PC build. Using the Intel Matrix Storage BIOS program, I configured them as RAID 0 (480 GB) and RAID 5 (2 TB) volumes.
Now I am trying to install Vista (x64)--as expected, the Windows installer prompts me for a RAID driver floppy. I have downloaded the latest ICH10R drivers from the MSI Website and copied them to a USB key--the installer detects the drivers on the key but when I click Next, I get the following error message: "No new devices could be found. make sure the driver files are correct and loaded on the driver installation media."
Can anybody help--I'm fresh out of ideas?
The P45 Platinum board is a rev 1.1. I have not flashed the BIOS so I suspect that it is v1.0 but am not sure how to confirm this.

Quote from: Jack the Newbie on 30-October-08, 17:39:54
When one of the board's controllers is set to RAID mode, it does not even matter if there are actually hard drivers connected to it, or not. Vista is not attempting to locate a RAID volume but simply needs proper drivers to be able to initialize the controller.
OK, makes sense. So when Vista was prompting me for drivers it was actually looking for the JMicron RAID drivers NOT the Intel RAID drivers. When I tried to install the Intel RAID drivers it--naturally--gave an error message.
It seems that it is no longer necessary to install Intel RAID drivers when you install Vista as these are already available to the OS (must be on the DVD).

Problem with MSI P45 Platinum DDR2 mainboard and Corsair Dominator PC8500C5D Ram

Hi, I have encountered with a problem.
First I had
MSI p45 platinum ddr2 bios ver. 1,4
Intel E8400
Corsair Dominator PC8500C5D 2x1Gb
2 Asus ATI EAH 3870 Crossfire
and it was running with windows XP without any problems.
Problems began when I decided to upgrade to 6Gb of ram and to install Vista 64. Ram modules witch I bought are the same Corsair Dominator PC8500C5D, but 2x2GB.
When i put them together adjust voltage 2.1v and timing 5-5-5-15 they fail mem test with huge amount of errors.
when I test only 2x2gb modules memtest sometimes doesn't open at all, sometimes just stops working on 8 minutes of test. couple of times they completed memtest without any errors.
Can someone advice what should I do and what could the problem?
Thank you for your answers.

1) the modules are not the same (the DDR2 chips are different)
2) as general rule, mixing 2x1GB with 2x2GB is a bad idea.
cheers
