K8N Neo Pl - PSU RAILS question

Hi guys,
I have two supplies and want to know to use for my PC (K8N Neo Platinum with AMD64 3000+). I have read around that the Wattage is not a true indication of a good PSU, so I am not using this reading. I have read the Current (Amps) values from both PSUs, but they present the info in different ways. Add to this the fact that I have no idea about PSUs, then it leaves me with much to learn
PSU 1 reads:
+3.3V
28A
+5V
38A
+12V
17A
-12V
0.8A
-5V
0.5A
[/list]
Whilst PSU 2 is a little more confusing. It has two current readings - one is Peak and the other Max:
+3.3V
Peak=30A
Max=18A
+5V
Peak=40A
Max=30A
+12V
Peak=20A
Max=16A
-12V
Peak=1.0A
Max=0.5A
-5V
Peak=1.0A
Max=0.5A
[/list]
Can anyone help me understand the following:
[list=1]
For PSU 2, which reading should I take - peak or max?
Which of the 2 PSUs is better (I guess this depends on the answer to question 1 above)?
What is the meaning of the different rails?
How close to these values should the PSU stay?[/list=1]
Thanks in advance for any help

this is the most common question here on the forum it seems
lots of info on it here
a quick search will pull up hundreds of threads on psu`s
psu2 states max continuous at 16a 12v peak is 20a 12v
meaning it will spike to 20a but will only hold 16 for any length of time...
psu1 who knows weather it is max peak or continuous amps at those voltages !
whatever they both seem very weak on the +12v rail which "could and prob will" present problems with a amd64 system.
ok suggestions ( single rail )

MSI K8N NEO Platinum Edition memory question

Hi there,
I've currently got a MSI K8N NEO Platinum Edition (Nforce 3) motherboard and 2X 512 MB Corsair Value Select memory modules (both double sided) running at DDR 400 - this runs completely stable and has done for a number of months. I would like to increase my memory to 1.5 Gig but there seems to be a lot of issues?
I originally planned to buy an additional 512 Meg Corsair value select chip and place it in Bank 3 - is this acceptable?
I assue that i would have to drop the speed down to DDR 333 from 400, could anyone tell me how much of a difference this actually makes (when playing FPS games Doom3 etc..) ?
Any help would be greatly appreciated as i've been looking through both this forum and the Corsair one and i cant seem to find the answer.
thanks in advance !

Just note that there are combinations of two sticks that will also make the board run in DDR333 mode (see page 2-8 of the manual). For example, using two double-sided sticks in DIMM2 and DIMM3. I've actually managed to get it to work at DDR400 in those two slots, but it's not perfectly stable and overclocking diminishes drastically. Bottom line is the system will work fine when forced to DDR333...as long as you don't expect to overclock the RAM to any significant degree.

K8N Neo Platinum USB Keyboard Question

I've been having problems with my Logitech PS/2 keyboard (mobo powers up, then immediately shuts down and requires power be disconnected before restarting). My office PS2 keyboard seems to work fine, so I will replace my current keyboard. I see that some here have better luck with USB keyboards, but when I try a USB board it isn't recognized until Windows loads. I have USB keyboard enabled in the BIOS. I haven't gotten around to fixing the front panel USB ports, and the D bracket ports don't work either, but the main ports work fine. If I did the wiring change for the front panel ports, would a USB keyboard be recognized earlier in the boot sequence, or should I just stick with a PS2 keyboard?

I just fixed my machine so the USB Keyboard and mouse work properly. I have a MSI K8N Neo Platinum (BIOS 1.4 8/27/04) and an Antec Sonata case. When assembled, the two front USB ports and the two D-Bracket 2 USB ports were not working. Also, I was unable to access the BIOS with the USB keyboard (worked fine with a PS/2, though). The four USB ports on the Motherboard were not enabled until after WINXPPRO(SP2) started to load (NUMLOCK light and optical mouse would light), preventing me from accessing the BIOS.
The cause of this problem was an extra black wire in the Front USB Port connector from the case. Once I removed the wire from port 10 on the case connector, all 8 of my USB ports worked fine. I am now able to access the BIOS with the USB keyboard (once I had unplugged and then plugged it back in) and my mouse shows power as soon as I power on my machine.
Cheers,

MSI p35 Neo-Fi & PSU compatibility question

Ok I have a new high end computer system that is missing a PSU.
I recently got Coolermaster real power 700w psu which obsiviously wasn't working with the mobo (couldn't boot). Now I'm returning that psu and I have to ask which PSUs are compatible with this MSI p35 Neo-Fi motherboard.
So right now I'm planning to get Corsar 650w TX or Xilence 600W. I don't really want to waste time on returning another PSU so if any of you have any suggestions it would be welcome.

I'm going for that corsair psu then, thanks for replying guys. It has gotten good reviews too so now I'm convinced it's good.
Quote from: Frankenputer on 14-August-08, 07:02:02
The 650TX is an excellent choice. I'm interested in what other components you are going to have in the system.

MSI K8N Neo Platinum Nforce3 250GB - PSU?

My sister in law have this board, MSI K8N Neo Platinum nforce3 250gb chipset, recently the power supply sounds noisy and a high frequency sound from the Antec Truepower 380W SP. Had maked an RMA to Antec and they had agreed to replace the 380W psu with SmartPower2.0 450W. But they asked me one question, that im not sure about:
"Make sure that your motherboard does not need the -5V. If you want more information on the power supply you can look at this link: http://www.antec.com/us/productDetails.php?ProdID=26450 "
So, do Antecs SmartPower 2.0 450W suits this board and what really is -5V for? As I read the manual, it said ATX 20 pin power connector: JWR1 and at pin 18: -5V
So does it mean this board need a psu that gives -5V on ATX 20 pin power connector and thos board can't use with Antecs SP 2.0 450W?

Quote from: syar2003 on 22-February-06, 05:10:37
Hi!
The K8N Neo Platinum (MS-7030) doesn't use -5v to anything.
So the -5v from the old atx spesification is not needed in your case.
WoW, thanks for fast reply!
So, it won't be any problem to use Antecs SmartPower 2.0 450W with this board then? Want to make sure about it, before accept Antecs offer for replacement and had spent over 4 days to find the problem with his computer. Really don't want to do it again.
This is his riggs:
Antec Sonata
AMD 64 3000+ S754
Corsair Value S. PC3200 DDR 512MB
Maxtor Diamondmax 9 250GB SATA
Maxtor Diamondmax 9 IDE 160GB
Sapphire Radeon 9550 Atlantis 128MB DDR
and
Accton ethernet card on PCI slot
MSI D-Bracket2
so
With the "new" Antec SmartPower 2.0 450W
Any problem with this rigg and PSU?
edit:
Dound this post that it said the board do need -5V and now Im confused?

Antec's work fine and dandy with a64's for the majority of ppl, the issue arises when it is heavily o/ced I don’t mean 220 o/c mine starts to have probs @ about 2800mhz up, the 12volt rail gets taxed and usually shows up in dropping back to desk top and blank blue screens or plain old random restarts when loading the system i.e. bench marking.
To give you some idea my system would drop to about 11.2v with my msi neo and about 11.6 on the asus, a lad I know has just brought a k8ne asus board with 3200 Newcastle and his is even lower. But with all the o/cing these days more ppls are trying it hence problems all though some really have nothing to do with psu's
Not a huge issue as most ppls with a64 will never see O/c’s like that
I think that was over at AnandTech the review on the 64 mentioned the problems
he was having with antec's when O/Cing
I should add with antec , my tagan runs sweet as and didn't cost a arm and a leg

K8N Neo 4 Platinum Questions...

I'm going to be upgrading to a 7800GTX soon and will have to replace my mobo which is a K8N Neo 2 Platinum. I am currently using an Antec True 550 ps, which has 30 amps on the 12v rail. However, it is only a single rail ps and it has a 20 pin connecter. I plan on upgrading to a K8N Neo 4 board and was wondering if my ps is still okay even though it's only a single rail. I read the sticky and it seemed to suggest that single rail was still preferable but I just wanted to make sure I wasn't mis-reading anything. Secondly, does the K8N Neo 4 use a 20 or 24 pin header? If it uses the 24 pin will I be okay using my current ps which is only a 20 pin? Moreover, would I be advised to purchase a 20->24 pin adapter or should I just plug the 20 pin into it's corresponding pins?
The rest of my system:
Winchester 3500+
DVD burner
CD burner
OCZ 2 GB (2x1024) Platinum DDR 400 memory
Haupaugge PVR 250
WD 160 GB SATA HD
Thanks for any advice

K8N Neo4 Platinum has compatibility issues with nVidia 7800 cards. There is a capacitor very close to the PCI slot which makes the installation impossible. You may search the forum for more info.
Your PSU is OK as long as you won't be overclocking as your card consumes a lot of juice/I'd still go for more Ampers on the 12V rail/. It's not really a problem whether you have 1 or 2 12V rails....The mobo uses 24pin header but 20 is OK as well....You don't need an adaptor for that.

Question for those with memory issues on k8n neo plat

I have been having issues with my memory on the k8n neo platinum board since i built the system last month and i just recently discovered a fact I had overlooked.
I Have discovered that if i test the system while it is cool (having sat turned off overnight for example), then memtest will pass the ram just fine and the system will be stable for a short period of time, generally longer if no intensive applications are used, ie. doom3 vs. websurfing).
This system, once it heats up ( seems mostly to be the nvidia 3 nb that needs to be "hot"- that is, a probe placed in contact with the module reaches about 58+ degrees c) then the system becomes unstable and memtest, if used, fails.
Prime95, if used on it when its cool, will usually take about an hour or so to fail, but if its used on the system when its been running a bit ( temps from nb at 58c+ and memory module hot to the touch) then it fails after about 20-30 seconds.
I have placed an active hs on the nb in an attempt to correct this, but temps still remain high with failures occuring.
I have spent the better part of three days testing the sytem this way and the above facts have held true in all these tests.
I have tested at stock ratings ( not using "auto" in bios, but using "approved ratings" of 10 x 200 for fsb and timings of 2-3-3-7 for my ram at 1:1 (which is recommended as well) since i am testing for base stability at this point;Voltages have been left at auto settings, however.
I was wondering if anyone else with memory issues could try this out and post if this seems to be the case for you as well.
Perhaps the memory issues on these boards are directly related to a problem with the nvidia 3 chipset running too hot?
Does anyone have a memory issue with these boards who is using water cooling on the NB ?
Lack of issues from people using 'problem" memory, but having no failures with water cooled nb's would support my assumption.

Yes i did mean chipset.
I am using a stock hs/fan from amd, which seems to run a tad hot but, considering that I wont overclock until I can get board stable, its not an issue. (runs 35-40 idle and up to 72 intensive). I need the warranty more then the extra mhz at present.
I removed the stock heatsink from the nvidia chipset and bought a generic chipset cooler (green, very little in the way of fins and seems to be aluminum) with a small fan.
I used a generic silver paste from Compusa to adhere both the cpu hs and the chipset.
I didnt lap either hs, just installed each as per instructions on artic silvers website (figured it had to go on the same way even generic).
I also bought a kingwin thermal center which i ran probes from to the cpu, case, and nb chipset.
I am not using it to adjust fans so those arent connected - its just a reference temp I can see at a glance, esp considering the funky bios reading this boards been known to give.
I assume from these responces that even a nvidia 3 250 chipset shouldnt get as hot as mine?
I asked about that from the retailer i bought this from but he seemed to think it was "ok" at 50ish celcius, but then again he didnt look too confident when he said it, lol.
Idle right now reads on Corecenter at 28 celcius for cpu and 33 celcius for the chipset, although, I have readings of 37 c and 43 c from the kingwin thermal center, which i believe to be more accurate.
My voltage reads at 11.67 for the 12v line at idle right now.
The psu i got is stick from the xblade case i bought in store. (http://www.xoxide.com/xblade2.html)
I have a dvd burner, cd drive, and two maxtor ide hd's attached to the system;The only card is the agp.
Is there a way to check and see if the cpu ispower starved? software monitor or even an external probe perhaps?
I havent put a probe on it, but the ram came in its own heatspreader, which gets very hot to the touch as well.
What temps should I be looking for on these items?

RAID Question? K8N Neo...

I just purchased the K8N Neo Platinum and noticed right away that my Maxtor 6Y08OMO 7200rpm SATA HD has just became a speed demon.. It now beats my 15K rpm Cheatah and my Raptors... My question is can I have two completely diferent RAID arrays? One for Windows XP on the two Raptors and one with the two Maxtors for high speed storage/video editing stuff???
Maybe like this:
SATA 1/2 = Raptors in RAID 0
SATA 3/4 = Maxtors in RAID 0
Can I do this on the K8N Neo Platinum?
If I can do this than I will be getting a second Maxtor right away...
Thanks in advance...

I love this board...
You can.
You should look into raid 0+1 for the raptors though.

K8N Neo Platinum Bios 1.3 XP 3700 heat question

i did do a quick search on here before posting this question but had a load of varying answers ... so
i have a K8N Neo Platinum Bios 1.3 an xp 3700 and core centre says the chip is at about 45 - 50 degrees when the pc is idle
this is with the stock fan that came with the chip and ive also tried a samurai heatsink and fan .... ive reseated and reapplied artic silver and also tried thermal pads as well and the temp on the processor always comes back as 45 ish degrees
is this normal as the pc seems to run ok and even after round of doom 3 the temps only seem to hit about 55
are these chips hotter now or is it a bios / thermal temp issue
cheers guys
ohh and nice forums BTW

yup, issue with temp reading -> 1.43 beta bios for K8N NEO pL. for me 36-39 idle 42-45 after a doom3 session

K8N Neo Platinum and 12V PSU

Hi!
I'm don't understand, that in the MSI Test Report for k8n neo are power supplies like Seventeam ST-300BLP 15A@12V, and here in the forum everyone says it must be >24A@12V?? I know it's true, becouse my computer with enermax 18A@12V restarts, and freezes.... but why are so weak power supplies listed in the test report??
batabub

I would agree with the sound advice from hansh for now, to answer your question, look at the spec of the test rig used, to call it minimal is an understatement, it makes a barebones system look like a server
Then look around at the specs of the majority of people in this forum with multple drives top end graphic cards etc.,
this thread may be of interest. New Computer getting random crashes/reboots

Quote from: Dream_true on 28-June-05, 08:14:40
Only BIOS 1.4 and above support Venice & San Diego. However BIOS 1.4 has shut-down issue with RAID. It is suggested that you let your reseller help you flash BIOS to the latest version 1.5. After flashing BIOS, Loading Optimized defaults is needed of course. Good Luck!
Support new features in that cpuid yes. But that is not the same as you are not able to boot/post your system
with an earlier bios .
I booted up a venice on a K8N Neo2 with an aged 1.3 bios (with no venice SD support) just fine .
If the bios supports 90nm cpu it will post .
New CPUID added means :
Shown on post (display)
And e.g new model spesific features (like e.g SSE3 ) enabled .
Use the CPUID instruction to properly identify the processor.
• Determine the processor type, stepping, and available features by using functions 0000_0001h
