Memory Controller not available - K8N NEO4 Platinum Ultra

Hi Experts!
I have typical problem in my PC. I need reply only from experts. Newbies please excuse.
My system displays the following info in POST.
VENDOR / DEVICE CLASS DESCRIPTION IRQ
===================================
10DE 005E 0580 Memory Controller NA
If anyone can correctly PIN POINTEDLY identify why this is displayed, it will be much helpful
As such I face no difficulty with my system. But this message very much annoys me.
Thanks.
My PSU Details:
400W. +12V 20Ampere. (This is the maximum I could afford in our indian PC environment.)
AMD 3000+ Winchester 90nm. CPU.
K8N NEO4 Platinum Ultra Mother Board.
512 MB Hynix PC3200 Memory. (2*256)
80GB Western Digital.
Ordinary PCI VGA 2mb card.
Samsung CDROM.

There is no driver for memory controller with A64 (nforce3/4) as stated earlier .
You see this in the memctrl.inf for UDP 5.10 , driver pack for nforce 3 and backwards down to nforce 1 .
Memctrl is only added to the 5.10 package for backward support to nf2 and lower as this is a unified driver package and
the memory controller is at chipset level on the motherboard that resides in the external northbridge on nf2 chipsets and lower .
What you see is just a vendor/machine id description and is just as it should be .

K8N Neo4 Platinum Ultra nForce4 no post.

Took the cpu off and cleaned it, upgraded the video card started the computer and no post. Led's 1,3,4, green 2 red. Took cpu out and checked it no bent pins, checked all connections. Sometimes when it boots it will have 4 green led's but no video. Tried another vid card same thing. Tried booting and holding the insert, cont+home, F1, delete keys. Get power to the fans and hear the HDD sometimes.

Anyway - could be fans causing it - I had my Neo not booting until I disconnected a case fan from the mobo fan header output.
Try with just leaving the cpu fan (could also be this one of course) .

Memory frequency problem with K8n Neo4 Platinum

I have 4 banks of memory installed:
2 x 256 GEIL ddr400 Cl2 and 2 x 512 CORSAIR ddr440 cl2.5, total 1.5Gb ram.
They are in dual channel mode, but they run at 100hz and not at 200hz.
If in the bios i set the manual mode for the memory and set 200 hz, than after the reboot they are at 200 hz but in games like wow, css or others the system freezes.
If i let the auto mode for the memory, the system set them at 100 hz and so the problems disappear.
I see the value 100 or 200 hz in the "cell menu->ddr rate". This value is confirmed from cpuz.
How can i set them to 200hz without system freezes?

Quote from: JayBee on 13-December-05, 03:27:53
3 gigs (256x2 + 512x2) is an inherently unstable combination. While the system could boot that way, you are asking the memory controller on the cpu to negotiate too much when it must run one channel at one type of timing and the other channel at an other. Even under the best circumstances, you can boot that way but will fail memtest when system is stressed. Only stable way to use all 4 dimms slots is with 4 identical modules (same size, cas, etc, i.e., same everything). When it comes to mixing sizes like that (2x256 and 2x512), Intel can do it (memory controller is on the board) but AMD cannot (memory controller is on the processor).
Edit- mixing brands (Geil and Corsair) is an other reason why it has to fail. Intel could do it. AMD cannot.
Edit Edit- What 400 Watt psu is that? Note that you need 18 amps on +12 Volt rail minimum for Neo4. Does your psu have that? Just because the label says it, does not make it so. Check what brand it is.
The output at 12V is 18A

Best Drivers for new K8N Neo4 Platinum Ultra 7125-010

Looking for just a little clarification on which drivers to load for this board. It is on the way with my CPU and should be here tomorrow. In reading through some of the posts, it seems to be a good idea to load the most recent drivers right from the start and not even use the CD that comes with the MSI board. Below is a list of the Drivers which I "think" are needed.
Graphics Video Driver; 78.01
Nforce AMD Driver; 6.66
Audio Driver; 4.62
In doing some further reading, it seems I may need the following also but am not sure??
Windows XP Unified Driver; 5.10
Which includes the following:
Audio; 4.42
Audio Utilities: 4.44
Ethernet; 4.42
Gart; 4.36
Memory Controller; 3.38
SMBus; 4.04
Installer;4.46
IDE NVIDIA; 4.46
My plan is to setup the build with 1 WD 37.6 Sata drive as the boot drive and only the drive to start with. As for my Internet connection, I am going to use my USB Gigafast Wireless to connect to my D-Link DL-524 wireless router. I am going to Disable all of the onboard LAN features. Part of my confusion at this time is, do I need all of the Windows XP Unified Driver package??? Thanks in advance for any help in clearing up my confusion. Also, is there a specific order in which these should be installed??
Regards; Pop's

No problem Pop,besides,I'm 42 now and still love to build on my computer
As for the link,you need the "AMD Athlon™ 64 Processor Driver for Windows XP and Windows Server 2003 Version (exe) 1.2.2.2"
or the one just above it "AMD Athlon™ 64 Processor Driver for Windows XP x64 Edition and Windows Server 2003 x64 Editions Version (exe) 1.2.2.1"
It will uninstall the current driver that was installed with the mainboard driver cd,and should install the newer afterwards,you can check in hardware device manager if the driver version is the newer for cpu after reboot.
Haha,yes,I had the same feelings before I build this system,reading all msi forums regarding mainboards.
And all I read was problems after problems.But I have another system based on the KT3ultra,which I build 3 years ago,and I'm still pleased with this system so I decided to stay with MSI for now.Also I noticed the problems were/are the same on the Asus platform,seems common on nforce4 mainboards.
As for building,just take your time,I had a slight incident with placing the heatsink+fan on the cpu socket,apparently in the corners of the cpu bracket is a small ledge(Énglish is not my nature language so don't know if I use the correct word) ,I couldn't get the retention lever in place,needed a lot of pressure and I became scared of damaging things.
So I waited a few seconds and tried again,suddenly with a loud click,the retention lever fell in place,the heatsink was hindered by this ledge in one of the corners from the bracket.So you have to place the heatsink correct and don't overuse the pressure you need for the retention lever.Slowly increase it,and all will go well.
Also I noticed the pcie graphics card fell right over the retention clip that holds it in place right besides the northbridge fan(well,actually on the left side from the fan),so installed once,it's very hard to get your finger behind to replace the card for example,or to clean it out from dust.But I used a small tool to get behind and press the clip for card removal(a bended metal tool,so I need to be carefull using this)
As for sata drives,I started with an ide to be on the safe side,but I do know you need the driver floppy disks for using the sata drive.
Can't help you any further with that for now,when I buy sata2 drives no doubt I also will need to check if I need a bios update etc.But that's with a smooth system already running,so I can take my time and redo any steps I made if things fail.
That's why you need to do the correct order of installing software,it's much easier then to fix problems that may arise.
Well,goodluck and don't be afraid,just take your time.

New Build Update K8N Neo4 Platinum Ultra 7125-010

I will report on the positive results of my build first. All installs went very smooth, no problems except for a bad floppy drive from the start which I did replace. I have 1 Sata hard drive on Sata controller #1. Installed XP Pro/SP2 Slipstreamed without doing the F-6 thing and had no problem with the Sata drive booting after install. I have a DVD/RW on IDE 1 as Master and a CD-Rom on IDE 2 as Master. The board is functioning very well for 5 days now. My only disapointment with this board, is the onboard sound. This is supposed to be better than my old K7N2 Delta L onboard sound. I am here to say, it is the very worst sound system I have ever heard. While getting the new build setup, I had a pair of $4.00 speakers hooked up and thought it was acceptable. When I hooked the build up to the rest of my hardware, which has a pair Altec Lansing speakers that sounded great with my old K7N2 Delta L, I was very shocked. Sounds like crap. Not much volume or other settings can make it sound worth a darn. Just can not figure out how the el-cheapo speakers sounded better than a pair of quality speakers. I have fooled with settings until the lady of the house is ready to pull my plug. Other than the sound issue, I do have to say this is one incredible machine. Guess if I really want quality sound or even something close, I will have to install a sound card.
Regards; Pops'
EDIT: Open mouth and insert foot. I was not about to quite give up on getting some decent sound from this system. Opened the Nvidia Mixer Application again and started fooling with selections. On the first screen, I had choosen the " 2 Speakers Mode ". Well, I started playing with the selections there and selected " 7.1 Speakers " and that made all the difference in the world. Now it is very acceptable. I am not real picky, but just could not figure out what happened when I moved the build to my office which had the Altec Lansing speakers and it sounded like crap without changing any settings??? Long story short, I guess it pays much reward to keep picking away at the settings.
Now I can go to bed and not have that grinding on my feeble mind.
Regard's again; Pop's the pooped.

Yep,the 2T setting is much slower compared to 1T.
What I did was this,I set the top row at auto,so that covers all the cas latencies.
Somewhere below is a second option on auto,I set this at manual.and changed nothing but the 2T to 1T.
One thing to note though,when I build my system I had some nvraid complaints when booting,still after disabling them all.
It needed a cmos reset to work properly.
Also I noticed in memory section from bios two settings in the bottom row.
read preamble value
max Async latency
They were both on 6ns. Setting them on 5ns makes things a little faster but also made my windows show some error messages just out of the blue.So I kept them on 6.
Now after a bios flash without resetting the cmos they were both set at higher numbers,thus more stability at a cost of some speed.
Again I had the nvraid complaints,so I needed to reset cmos (which is commonly recommended,even by MSI) and noticed the 2 memory settings are back at 6ns.
This led me to believe the board picks this up automatically after a clear cmos.
So no need for you to change any setting in bios except for the 1T option.
You will understand what I mean when you visit this bios memory page.
On a side note,I run at stock speeds also,except for the cell menu,I use agressive timings as enabled,speeds up your ram a bit also.
Ofcourse you have to try if it works on your system since you got different memory compared to mine.
Goodluck...

K8N NEO4 Platinum Ultra 4 Green Lights NO BOOT ??

I have a rig that is less than a year old. This morning when tunring on with the power button, all that happens is I get 4 green lights on the D-Bracket. No post screen or video. All fans are running and power supply seems fine. Re-seated the video card and memory modules plus did a bios reset with the little red button. Still no go. Does anyone have some advice on where to start?? Hard drive light does not come on at all. I also checked all connections to the hard drive and motherboard from the psu, all seem OK.
Thanks; Pop's

Bas; I put the MB on the antistatic bag it came in when removing it. I then use a piece of clean cardboard to do the testing on. Was not aware of the bag being conductive though and thanks for that information.
qyx; The power cord was pulled and I always press the power button on the case 3 times to help discharge the PSU and then give it a couple minutes before taking off the side panel and doing a reset of cmos. I closely looked at the MB mounting studs and panel for any possible shorted areas. It all looked very good. What stumps me is this machine has not had one single falter since I built it in Sept. of 06. Just would not start up on Sun. morning. My one possible thought is this, the little woman just purchased us some cozy slippers that are all leather, soles and all. They are fleece lined. They are horrible for collecting static. This is her machine and it is almost identical to my build except for the CPU which is a 3700+ and the video card is one down from mine which is the 6600 lite. It is possible she gave off an ESD to the power button when shutting it down or starting it up. Don't know for sure and I am not going to go there at this time. Just easier to fix the machine and warn of the slippers used near the computers.

Share ShutDown hang solution on K8N Neo4 Platinum Ultra

From BIOS 1.0 to 1.64, my Neo4 CPU load to ~70% with System Idle is always 99% after some times. When shutdown, it always hang at the last shut down screen "... shut down...". I have two Hitachi 160GB SATA HDD connected to the Nvidia port (non-RAID mode), under drive C and D.
Lately, I found that the drive D is not responsive under such scenario. After reading the troubleshooting guide http://aumha.org/win5/a/shtdwnxp.php, I try to disable the "Turn off hard disks" in the "Power Option properties" menu. Amazingly it solves the problem!
I do not know the reasons behide but I hope the real solution can be come out soon, whether it is the Nvidia driver problem or is a BIOS issue.

brianwtl,
I am running the Neo4 Plat/SLI and the solution to the hang on shutdown was in the BIOS in this thread:
New Award 219 beta bug bios needs testing
So there should also be a BIOS solution for the problem.
Take Care,
Richard

Looking For A K8N Neo4 Platinum Ultra Board

I have had my 2nd MSI board fail and it is now out of warranty, GRR. Looking for a compatible MSI board but am not having much luck other than Ebay and I am not sure if I want to go that route. My cpu is the AMD Athlon64 4000 and I have 2 matched OCZ memory sticks which are the 400/3200 I think. Does anyone have a good suggestion for a board that would be compatible with this hardware?? Thanks much.
Pop's

BOSSKILLER; Thanks for the come back. Yes, I am finding that out but still searching. I have found a couple new ones but they are overpriced. One is $146 and another is $124 plus shipping. Don't know for sure if it is worth all that at this point yet? I may just part out the machine before it is over, going to keep looking for a couple days yet though. This was the main ladies machine and she got frustrated and bought a huge 22 inch HP TouchSmart with Vista on it of course. That new OS does not show me much yet, slow and glitzy though.

Anyone get 2gb Memory to run at 1T in K8N Neo4 Platinum SLI MB?

I recently upgraded to 2 GB Geil memory in my new K8N Neo4 Platinum SLI system (not the system listed in my signature). I cannot get it to boot if I set Ram to 1T.
Has anyone been able to run 2GB at 1T in this MB?
Thanks.
fafner

Thanks all for your comments.
I have the Geil Value 2x1gb dual channel kit. It is rated at 3, 4, 4, 8. I can get it to run fine at 3,3,3,8 at 2T. I cannot get it to boot at 1T with either the rated settings or the faster settings. It will boot at at 2.5, 3,3,8, but is not stable.
I can exchange this kit for a higher quality kit, but I don't want to do that unless someone else has had success with runing 2x1gb in this Neo 4 Platinum SLI board.
The memory I have runs at 1t in my K8Neo2 system as my does my Kingston Value RAM (2x512). It so happens that I have 2 Kingston value kits (total of 4x512), which I could try but everything I have read says it will run at 333mhz with four stix.
My experience has been that the K8N Neo2 Platinum is more accepting of value memory in general than the K8N Neo4 Plat/SLI. I have also read that getting any 2x1gb kit to run at 1T in the Neo4 Platium/Sli board is impossible or at least nearly so. That is why I am looking for soneone who has success (or no success) with 2x1gb sticks at 1T in the same mb as mine.
Net I want to get the best 2gb configuration possible but onle one that someone already has experience with (since I can only exhange the Geil kit once).

K8N Neo4 Platinum: SiI 3114 Raid 5 is anyone doing it?

I've scoured the internet google, yahoo, etc. I can't find one single review of anyone using the SiI 3114 chip for raid 5. I want to put 4 sata drives on the SiI 3114 controller in raid 5 but I am concerned about performance. See, I am putting together a home media server and these drives will be written to often and read from constantly - 24/7. Originally I wanted to get a hardware raid 5 controller however I ran into a few problems. There are no current mobos that support PCI-x (if you're not aware PCI-e and PCI-x are not the same thing) and sataII/PCI-e/any current technologies. This is a problem because all hardware raid 5 cards use PCI-x. Sticking them in a standard PCI slot will kill performance and is pretty useless. There is one exception which is the Areca cards but they are all over $500 (actually closer to $1000) and thats overkill for a home server.
So all I would really like to know is if anyone has experieince with, seen a review, knows a friend - anything - that can tell me how bad the performance of raid 5 on the SiI 3114 (the 2nd sata controller on the K8N Neo4 Platinum) is. I am quite anxious as I have spent almost 2 weeks looking for all this info. I know the SiI 3114 is a software solution, so I am not expecting anything amazing spped-wise, but I do need it to perform smoothly. I will be putting an AMD64 3500+ with a gig of crucial ram (2 512mb sticks) in this box and there will be no overclocking.
Someone please enlighten me? Thanks alot!

Sorry but I can only assume you are reffering to the SLI board which only has 2 ports. The non-sli version has 4 ports.
See here: http://www.msicomputer.com/product/p_spec.asp?model=K8N_Neo4_Platinum&class=mb.
Quote
Silicon Image's SATARAID5 supports another 4 SATA ports(SATA5-8). Transfer rate is up to 150MB/s
- RAID 0 or 1, RAID5, RAID10, and JBOD groups are supported
- Support up to 4 SATA devices connected to a single controller
I've been struggling with a way to get raid 5 on an nforce4 chipset for almost 2 weeks. So I've done my homework though I am not a tech expert by any means. Actually, this has been a thorn in my side till I discovered this new MSI board. I understand that more PCI-e raid 5 cards will be comming to market this quarter but, I assume, they will probably fall in the Areca's price range. So I'm hopping MSI has come to my rescue :D. Otherwise I have to buy an old technology operon board (no sataII, no pci-e, no anything current) and server hardware is totally out of my technical experience so I would like to avoid that if possible. Also, if I didn't mention it, what I want to do is use raid 5 with this chip with all 4 ports (4x250gb sata drives). Thanks!

MicroStar K8N Neo4 Platinum 54G - nForce4 Ultra Avilability in CZ

Hi all,
does anybody know when M/B MicroStar K8N Neo4 Platinum 54G - nForce4 Ultra will be avilable in Czech Republic (Europe)??? I'm waiting two months for it...

Not really (maybe AC97 Controller = Auto was the closest). But, I tried now to switch the LAN cable to the upper RJ-45 slot instead of the lower one, and it seem to have stopped the power on peculiarity. Now only if I could pinpoint what's the broken component that causes the boot screen freeze and what causes the 35-45s idle time at the Win-logo loading screen.
The freaky boot screen freeze happens something like this:
1. the mother board model number is shown
2. the CPU information is shown (or sometimes this is skipped and not shown)
3. here it may or may not freeze and usually it produces this terrible out of sync mess (and monitor has to be switched off to get it back to normal)
I don't see any connection to overheating, I never touched any overclocking settings (or any other settings for that matter, it's a 2-day old installation).

K8N Neo4 Platinum nForce4 Ultra and 4 GB SDRAM DDR 400 Problem

I have the K8N Neo4 Platinum nForce4 Ultra and 4 1GB sticks of Corsair ValueSelect DDR 400 (PC 3200), model VS1GB400C3, filling all four slots. The BIOS recognizes about 2.88 GB of total memory. The MSI manual states:
Quote
Due to the South Bridge resource deployment, the system density
will only be detected up to 3+GB (not full 4GB) when each
DIMM is installed with an 1GB memory module.
I'm not sure what this means. Does it mean that I'm "wasting" my SDRAM, that not all of it is used, or does it mean that all of it will be used and the BIOS just reports a smaller number?

Hi.
You seems not familiar with X86....
As you should know, Windows XP and most OS are 32 bits. That mean that every memory pointer is 32 bits, thus allowing to address 4Gb of memory.
BUT
In most OS, there is a difference between the kernel and the user. So, in most OS, the memory is divided in two 2Gb block (no matter how many Gb of Ram you really have!). The first one is for the OS, the 2nd for the user program.
So, If you have for example 3Gb of ram, in the best case, you have 1gb for system and 2Gb for user program.
To allow more Ram to fonction, PAE (Physical Address Extension) was made. Instead of 32, you got 36 bits for you pointers.
But as X86-32 CPUs can't handle more than 32 bits, a reserved area was made within 4Gb to allow Memory to be copied from the area the program want to read.
Exemple:
You got a server with 8Gb of ram. In windows, you only see 3.5+512Mb PAE.
If a program need to address memory in the 7-7.5 Range for example, the chipset copy the data from the 7-7.5 range to the 3.5-4 range in order to allow the CPU to get access: that's VERY slow.
So, in short: You can't have and don't need 4Gb of ram on 32bits OS.
(And there's even more place occupied by every card (AGP, PCI, PCI-e)....)
That's why XP64 is so interresting for programmers who needs lots of ram (Database....). When used with a chipset who know how to deal with lots of ram (I don't know if NForce4 can do it but I doubt it), you can load in memory a 4Gb Database.
But In all case, the bios should say 3.5Gb, not 2 and so on. You must have a problem with one of your stick. My guess is that they are all double sided and that you should slow down the memory to 333MHz.
(Or better: Send back 2x1Gb stick and get 2x512 SINGLE SIDED stick, unless you REALLY NEED 1.5Gb for your system !)

K8N Neo4 Platinum SLI memory incompatibility

Sorry if it is an duplicated post, but i'm in a hurry and can't find nothing about this subject.
I'm sure i'm not the first to have this problem.
My memory (Samsung DDR 400Mhz - 512Mb) does not work on my MB. Though a friend of mine has a generic type 256 and it works just fine. With my memory the computer doesn't turn on, and start that beeping thing...
I hope you guys won't worry about bad english (I'm brazilian).
Thanks.

Hi again,
Well, if your RAM works fine on that computer, you can do some things to clear things up between your RAM and your Mainboard. You will need your friend's RAM once more to do this, as yours refuses to work yet:
1. First of all, and I know it seems a little dumb, make sure your RAM is installed correctly. As you may know by now, DDR RAM only fits in one way. If installed correcly, you should barely see the gold contacts of your RAM.
2. Try to find out if your RAM is supported by your K8N Neo4 Platium, by reading the Test Report :
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_trp_detail.php?UID=637
If SAMSUNG memory is listed there, it will appear as "SEC". Please note however, that many memory manufacturers use SAMSUNG chips for their memory sticks, so it may be a memory stick made by Kingston, Corsair, GoldenRAM, Spectek, etc. or even be a Generic Brand.
3. If you have not updated your K8N Neo4 Platium BIOS yet, this could be a good time to do it. Be sure to:
* Find, download and use ONLY the correct BIOS for your mainboard. For that look for it by using two IDs: The Mainboard Model (K8N Neo4 Platium ) and the mainboard Model Number (MS-????). You will find these numbers between the PCI slots of your mainboard, write them exactly as they appear there and then look for a BIOS update for that specific model.
* Prepare, in a NEW floppy disk, a BIOS rescue disk, just in case something go wrong during the process. To do so, please read : http://www.msi.com.tw/html/support/bios/note/boot.htm
* Be sure to disable any BIOS WRITE PROCTECT function your board may have. It could be a hardware protection (via jumper) or a software protection (via BIOS)
If its a hardware protection, set your jumper to WRITE ENABLE. If a software protection, set the BIOS WRITE PROTECT feature to DISABLED. If you can't find this feature, or don't know where are they located, please check your mainboard manual for it, and follow the instructions to disable the BIOS WRITE Protection, before attempting to flash the new BIOS.
* Run the BIOS update from a DOS prompt if possible. For that, use a NEW floppy disk, as old disks may just fail in the middle of the operation and you may end with a useless mainboard.
* Do not power off or reset your PC during this process or you may also end with a useless mainboard.
* If you can connect your computer to a working UPS before attemping to flash the new BIOS, it would be great, as it will continue to supply power to your computer in the remote event of a power failure (Blackout or "Apagon" in spanish)
* VERY IMPORTANT : Let the process to FINISH by itself. It may take a while, but please do not reset or power off your PC. Just power of or reset your computer ONLY when the Flash Utility directs you to do so.
4. Once you have flashed the most recent BIOS to your K8N Neo4 Platinum mainboard, try your memory again. It may work now. If it doesn't then you could be right about some incompatibility between your RAM and your mainboard.
For now this is all I can suggest you. It doesn't appears to be a Power Supply Unit (PSU) related problem as your mainboard works well with your friend's RAM.
Well I hope this helps a little.
Good luck!
