K9N Platinum Ram Voltage??!

Hello dudes!
Can someone tell me what ram voltage K9N Platinum is?!
O ill buy some memories, with 1.9 or 2.0v... and just wanna know what is ram voltage of this mobo...
i know asus m2n-e max is set to 1.95v... but dont know about K9N platinum...
So... if anyone can help me, i ll aprecciate..
tnkz a lot!
Ahhh... almost forget... is OCZ compatible with this mobo??!
Tnkz a lot!

I have the K9N Platinum motherboard aswell, and the standard DDR voltage is 1.80
OK, let me make it clear. there is no standard voltage on the mobos. the default voltage depends on the memory you are using. different memory modules will default at different voltages, as per the data that the manufacturer placed in their SPDs.
if you are talking about JEDEC default voltage for DDR2, then yes, it is 1.8V, with a maximum of 2.3V. you can read about timings and voltages for the JEDEC standard here:

K9N PLATINUM RAM Issue

Hello there,
I have the following:
* AMD Athlon 64 X2 4200+
* K9N Platinum
* Kingston 1GB DDR2-800 Ram Dimm (PC2 6400, KVR800D2N5/1G) X4
* EVGA 512P3N802DX GeForce 8800 GT 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready
* Western Digital 250GB (7200rpm, 16MB Cache, SATA 2)
* no other peripherals
* Vista Home Premium SP2 32bit
* Thermaltake Lite Power W0294 PSU (500W)
DC Output +3,3V 24 A
DC Output +5V 24 A
DC Output +12V1 18 A
DC Output +12V2 18 A
Issue:
Installed 4GB of RAM and on boot-RAMcheck shows 4BG RAM OK.
Windows sees and reports this: Physical Memory, Total: 3070MB
I removed one by one the sticks and also swapped slots but the result is always the same.
Any ideas?

You are using a 32bit version of Windows. A 32bit operating system provides an address decode space of 4GB. Not all of the address space can be used for the system memory. Part of it needs to be reserved for addressing other devices (so that they can function). That is why it is actually impossible to full address 4GB of RAM with a 32bit OS. The amount of usable memory may very between 2.5 and 3.5 GB, depending on the system configuration.
Solution: Use a 64bit operating system.

K9n platinum voltage question

Hello everyone,
I'm new to the boards and I hope someone can help me out.
Let me throw my specs out first:
mobo: msi k9n platinum 1.0 (bios 1.5) (ms-7250-20)
cpu: opteron 1212 (voltage should be 1.3/1.35)
ram: ocz 6400 platinum (5,5,5,15 2t) (2.1v)
gfx: evga 7800gt
ps: sunbeamtech 550w(+3.3v=28A, +5v=36A,+12v1=20A,+12v2=18A(30A/35*A))
This board does have the shut down problems, but I have done the work arounds and fixed 98% of them(memory timings were the most important to fix these)
My question is how do I set the volage for the cpu? I know go into the cell menu->cpu freq config->and change the voltage...but when I set it to 1.3~1.35, the cpu voltage in the H/W monitor & on the main cell menu page will show a .28 voltage increase. My cpu temps are also through the roof (35 idle/ 68+ load).
Right now I have my cpu voltage set at 1.25 and it seems mostly stable, but the cpu Vcore shows 1.528v in H/W monitor, and cell menu.
Also if I keep my voltage at 1.2 my temps are very low (20 idle/ 38 load)
When I use cpu-z it shows the voltage that I actually set.
Anyone have an answer or fix?
Thanks for any and all replies.

leave CPU vid to Auto, you no need to change CPU vcore. voltage moving -/+ 0.05 is normal.
take care about CPU temp... your CPU is overheating and become instable, 68C+ is very high... re seat CPU ensure its mounted well, aplly new thermal paste, but do not put too much!! here are few wrong examples:
your under load temp should not exceed 55C. you may need to get better CPU cooler if no change.

K9N Platinum, 4GB of RAM, XP shows 3.25GB

I have a K9N Platinum with 4 sticks of 1024MB Corsair. On POST it detects full 4096MB of memory. CPU-Z also shows 4GB.
However, in XP, right-click My Computer, properties, it shows 3.25GB of RAM.
Now, I did some googling and the solution to this seems to be that you must enable H/W memory hole remapping in the BIOS. However, the only option I see in my BIOS (v1.1) is Software Memory Hole. I have tried enabling and disabling this, but it has no effect -- XP still shows only 3.25GB.
So I guess I am wondering if there is a newer BIOS available that has the H/W memory hole option and hopefully that might solve my problem.
Any other suggestions or insights?

Win XP Pro (32 bit) will only show 3.25GB of RAM, the rest is then used as virtual memory (as far as i am aware) If you install 8GB of RAM, while in Win XP Pro (32 bit) it will only see 3.25GB. If it doesnt show that and you have installed more than 2GB, you may need to use the /3GB switch in the boot loader of Win XP Pro.
The BIOS should see the full amount of RAM anyway.

K9N Platinum and Corsair CM2X1024-6400 **UPDATE - FIXED**

I'm trying to help a friend with their new K9N Platinum motherboard. We got everything installed successfully, but after getting into Windows, the machine will just freeze up randomly doing anything, software install, whatever, within a minute, or sometimes as long as 5 or more minutes.
Basic specs:
K9N Platinum motherboard
Flashed to BIOS version 1.4
AMD Athlon64 X2 3800+ (65W) socket AM2
BFG Geforce 7900GS
500W PCI-E power supply
Wester Digital 120GB 7200rpm SATA HD 8MB cache
Single 1GB stick of Corsair CM2X1024-6400 RAM (DDR2 800MHz) - Brand New - DIMM slot 1
Windows XP Professional with SP2 and all windows updates installed. (using IE6)
Installed all latest drivers from MSI's website for this board.
We tried 1st with DRAM timings on auto, then tried to set the timing manually according to Corsair's spec sheet for this module, including memory voltage at 1.9V.
We think it might be a bad memory module, because after getting into Windows, we run memtest, and errors are detected within the 1st minute. We have RMA'd the RAM module. I'm wondering though if we just didn't have the timing for the memory set correctly in the BIOS.
Is anyone here runnning this exact memory successfully, or is this board incompatible with this Corsair module? If you are running successfully, did you have to change the SPD timings manually, or are you running using the SPD Auto setting?
If you had to use manual setting, any help with the values to set in DRAM Timing would be greatly appreciated. As much detail as you can provide would be great. Thanks for your help.

Ok, still having major problem with running world of warcraft. This PC freezes/locks up in the game every single time within 5-10 minutes of play no matter what we've tried so far. This is not a shutdown or restart problem, just a freeze/lock-up symptom. I'm getting a bit frustrated at this point. No other problems in windows are encountered. We can work in windows with any other application, like adobe photoshop or any other software, with zero trouble. I'm beginning to think this is video card related somehow with this 7900 GS card.
For added info, the video card being used is this;
BFG Tech BFGR79256GSOCE GeForce 7900GS 256MB 256-bit GDDR3 PCI Express x16 Video Card
Chipset Manufacturer NVIDIA
GPU GeForce 7900GS
Core clock 525MHz(vs. 450MHz standard)
PixelPipelines 20
Memory Clock 1320MHz
Memory Size 256MB
Memory Interface 256-bit
Memory Type GDDR3
3D API
DirectX DirectX 9
OpenGL OpenGL 2.0
Ports - DVI 2
The mouse used is a logitech USB track ball mouse if that has any bearing on anything. No mouse troubles though, just thought I'd mention it.
Here's what we've tried so far;
Updated to BIOS version 1.4. This was done after the Windows XP install though, so not sure if something is hosed up here.
1) We set the RAM timings to 5-5-5-12-2T and 2.1Volts in BIOS manually, as per direct recommendation from Corsair.
1a) Ran memtest all night for about 9 hours straight and no errors at all detected. So I'm guessing this isn't a RAM problem really, but who knows .
2) Installed the Windows XP SP2 Hotfix for Dual Core Processors - hotfix KB896256
3) Installed the AMD Dual Core Optimizer from here -->http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_13118,00.html
4) Updated the Nvidia system drivers with the nForce 550/570/570/590 SLI (C51+MCP55) driver package 9.19 WHQL from MSI's website here--> http://www.msi.com.tw/program/support/download/dld/spt_dld_detail.php?UID=730&kind=1
5) Currently running Nvidia video driver version --> ForceWare Release 90 Version: 93.71 Release Date: November 2, 2006 WHQL Certified.
6) Ran a complete Direct X diagnostics via dxdiag. All tests passed successfully.
7) Tried to install the AMD Athlon™ 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (x86 and x64 exe) 1.3.2.16 from here -->http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_13118,00.html
But it would NOT install because it says I have to first uninstall the current driver via add/remove programs, but it's not listed there, before installing this one. So, I have no idea where to look or how to do this, I'm afraid of messing up the processor driver. Can someone explain how to install this driver, and would not having this installed possibly be a potential cause of the game lock-ups?
I don't know what else to do. Could the version 9.19 Nvidia SATA or IDE drivers I installed be causing these game lock-up problems? If so, do I just go into device manager and just rollback drivers for all of the devices listed under the "IDE/ATA ATAPI Controllers" in device manager?
Again, this was a fresh windows XP Pro install on a newly formatted hard drive. Obviously something is fubar, but I'm running out of things to try. Maybe going into BIOS and "load optimized defaults" and start over?
Lastly, the tech specs on newegg.com for this video card say "A 350W PCI Express compliant system power supply (with 12V current rating of 22A or more)" is needed. Since the 500W power supply we're using has 2 separate 12V rails rated at 20A each, could this be the problem?? I'm open to suggestions. Thank you.

K9n platinum memory

I just purchased a k9n platinum motherboard.Does anyone have any suggestions on memory for this board? I was considering corsair twin 2x1024-5400c4 or kingston khx5400d2/1g.Also I am not sure if i should go with dual channel or single {does it really make much of a difference with dual channel}If i go with the corsair memory can i still use the default settings in the bios.The k9n board supports 1.8v, the corsair uses 1.9v will I have to change bios setting for this ram. Thanks for your help

Quote from: Steyn on 07-November-06, 03:16:30
The board's default voltage is 1.9V. You can however set the DDR voltage from 1.8-2.45 Volt.
default voltages depend on the memory SPD defaults not on the mobo. so if the memory modules have a 1.8V SPD default, the BIOS will set the memory at 1.8V.

Planning To buy MSI K9N Platinum + AMD X2 3800+

Hello everyone,
as the title as Iam planning to buy a MSI K9N Platinum board with an AMD X2 3800+ for a new system build. Ive been out of the game for a while, the last time I was really up to date on computer technology is when the AMD XP 2500+ Barton was the hottest thing on the market, some what of a new comer to dual core technology. I have a few questions, mainly about the board it self. I did a little searching and that answered some of my question but I have a few more.
Ive read a lot about the shutdown problems from the board when transferring large files or burning DVDs. I have a few questions about that.
From what I see so far, this is a very informative forum and I appreciate any and all information. So here goes:
1) It says on the MSI website that the ram slot for this motherboard is at 1.8 volts. The ram Iam planning to get is OCZ Platinum EL XTC PC2-6400 1GB 2X512 DDR2 CL4-5-4-15 240PIN DIMM Dual Channel Memory Kit. On the OCZ website it says that the ram modules run at 2.1 volts. My Question is if I stick this ram in the mother board will it boot long enough for me to go into the bios and change the ram voltage to 2.1 volts?
2) Now Ive read about the shutdown problems with this board. Ive seen a lot of people up the VCore to 1.35V. If I do this along with a bios flash, will this take care of the problems?
3) Now the dealer that Iam buying my PC from didn't have this board in stock for the last week. He just got them in 2 days ago this week. Therefore Iam assuming he has the lastest version of these boards. Now are these problems taken care of on the new version of these boards? If not what can I do to get rid of them?
4) Is there anything else I should know about this motherboard?
Thanks for the the help.
Ron

Yes, you could set up manually the voltage to 2.1v perfectly I've got one k9nsli p, with an amdx2 3800+ whit 2gb ddr2 (512x4 twins pack corsair xms2 ddr2 800) that works at 1,9v
2) Now Ive read about the shutdown problems with this board. Ive seen a lot of people up the VCore to 1.35V. If I do this along with a bios flash, will this take care of the problems?
My shutdowns problems was resolved by unnistallin' nvidia IDE controller, nothing about vcore or flashin bios... I keep original bios version 1.0 & Core center shows vcore at 1.33v
3) Now the dealer that Iam buying my PC from didn't have this board in stock for the last week. He just got them in 2 days ago this week. Therefore Iam assuming he has the lastest version of these boards. Now are these problems taken care of on the new version of these boards? If not what can I do to get rid of them?
Good question... 2morrow I'll check on the box of my k9 the part number and will post it
4) Is there anything else I should know about this motherboard?
The first week, I was desire burn my k9 shutdowns... shutdowns.... shutdowns... after I find the cause of that ShiX$/#(! (nvidi IDesuxs controller) my life is happy!
good luck
Thanks for the the help.

K9N Platinum and OCZ2P8001GK

Hi. I bought 2 OCZ PC2-6400 512MB DIMM (OCZ2P8001GK) and I am thinking of buying the MSI K9N Platinum (non-SLI) board to run with AMD Athlon X2 3800+. Will it be any compatibility problems running the system with those memory modules? [Running at stock speed (at least), both CPU and RAM (800)].
thnx for any info.

i plugged all the above together, inserted only one ram module in dimm no2 socket and the system boot just fine...the cpu clock on memtest86+ v1.65 says athlon x2 1005mhz, is that correct?i will let memtest run for half an hour and then plug in the second ram module. the m/b has bios version 1.0 (!!) but the memory is normally recognized at 800 mhz as it should be.more soon...

K9N Platinum Sli trouble

so i have assembled my new system:
Athlon 64 x2 AM2 4200+
Zalman CNPS9500
K9N Platinum Sli
OCZ DDR2 PC2-5400 667MHz EL Gold Edition 2GB Dual Channel Kit
XFX Geforce 7600GT 256mb XXX edition (another one will be added today for SLI)
a SATA drive and a DVD burner (these arent important for the issue)
temps = idle 30-34 c, load - no idea havent checked that yet
Enermax Liberty 400w PSU
ever since ive assembled the system i ran into some strange thing - during the changing of setting in the BIOS it froze a few times.
Neverthless i was able to run the system, install windows, start to install other software (yesterday)
and today when i turned on the system, windows booted up, and sudenly it restarts and freezes up in pre bios stage...
Reset or Shutdown resulted in power up, but nothing happening, the monitor did even got out of standby...
after a few tries, and about ten minutes without power, it started up and went to a bios stage, giving a CMOS Bad Checksum Error... loaded bios with fail-safe settings, system worked fine and booted up windows... windows worked fine aswell, attempt to reboot and change the bios settings, gave a Bad Checksum from start and a freeze in bios. System is not getting to bios stage once again...
A Mobo problem that warrants a vist to the store, to return it?

Quote from: mr.flint on 25-August-06, 00:11:37
oh and the PSU got two +12v rails with 20a on each, should be enough?... (though Enermax seems to have troubles with math since according to them 20a+20a=30a)
trust me, enermax doesn't have problems with math. this is actually how it works. you cannot just add up the 12v rails to get the max amps on the 12v.
Quote from: mr.flint on 26-August-06, 00:33:23
managed to boot with the suspected mem stick - running memtest-86 - counted 746321 errors and then froze.... looks like the stick IS defective
try to increase the memory voltage a bit. i think you should be safe up to 2.1V. if you still get errors in memtest, then you have a faulty memory module.

K9n platinum ?

hey can any1 put me out of my misery
i just bought the msi k9n platinum board,and the
ATHLON 64 X2 6000+ 3.0GHZ PIB SOCKET AM2

and then i also got the
Corsair TWIN2X2048-6400C4 2GB Kit DDR2-800 XMS2-6400
now my concerns is that when i read about the board it says that the ram is 1.8v and the ram i got is 2.1v,will that be a prob?
and when i looked on the website it didnt say that the board supported the 6000+ cpu,will it work on this board or do i hav to get a new 1?

thnx,well i got the ram and i got me cpu,im just waiting 4 the mobo now and then il c if it works,il post the result

K9N Platinum bios version & cpu support

Hi!
I need some help to clear up some questions regarding my MB.
MB: K9N Platinum, Cpu-z states my bios version is 080014, but i cant see it in the bios list for my MB, so what version is it?
Im currently running with a Athlon X2 5200+ Windsor, and i have got my hands on an Athlon X2 6400+ Black Edition, as far as i can see my MB is supporting that cpu, but is my current bios up to date for the cpu?
I have downloaded the MSI usb bios flashtool and i have set it up, and it boots in dos, but when i run memtest the program just says in one line memtest and a flashing + nothing more happens (i have left the pc for about 3-4min but no change) i feel that im starting to push my luck, and i dont want to kill this MB since its my work and gaming rig.
System spec:
MB: K9N Platinum
CPU: Athlon 64 X2 5200+ (want to install Athlon 64 x2 6400+ BE ID: ADX6400IAA6CZ)
RAM: 6Gb DDR2, 2x1Gb, 2x2Gb
GPU: GIGABYTE GTX260 Super OC Edition
PSU: CORSAIR HX520W

I need atleast Bios 1.8 to get my MB to work with the new cpu.
So now i just have to figure out why mem test wont run.

Memtest do have some bugs. You can do test with Orthos instead:
https://forum-en.msi.com/index.php?topic=103598.msg760534#msg760534
To check is your system is stable or not.
Once done you can ignore Memtest when asking after booting from the USB key
Also leave 1 memory stick only temporary in the 1st DIMM close to CPU socket before BIOS flash.[put remaining sticks back when BIOS flash is done/finished].

K9N PLATINUM(NON SLI) DUAL CHANNEL MODE PROBLEM

put a new system together with the following specs:

not overclocking or even trying to.
no sata drives connected.
has never failed to post,boot windows and no lockups or blue screens.
ok,i am trying to get the memory to work in dual mode.
everytime i put the memory in the dual mode slots,the cpu clocks down to 1ghz instead of 2ghz.
verified by bios,windows and cpu-id
i have tried different memory(both ddr2 533 and 667)667 installed now.
also never had any install problems with windows and everything runs fine until i tried dual mode.
after the cpu clocks down to 1ghz,the only way to get it back to normal is a bios reset( load defaults
or press red button).
if i leave the memory as single channel then i have no issues.
also cpu-id says the chipset for my board is nforce 550,i thought k9n platinum had 570 nforce chipset?
this might just be a problem with cpu-id though.
any thoughts on the cpu down clock problem in dual channel mode?
thanks,jeff

1 assume you can get into BIOS with 1 stick only?
Go into the BIOS and manually set the timings and voltage to what your memory manufacturer recommends. Use a 2T command rate and see if it works.
Try both "sets" of dual channel slots, i.e. the two left slots or the two right slots.

K9n Platinum Won't Post!!! Memory Incompatible or Mobo failure???

Like so many others, I am having trouble with my K9N PLatinum. When I turn the system on, everything powers on, CPU fan, case fans, leds. It begins to post, no video, but the D bracket just hangs on (1, 3, 4, red and 2, green). I have tried all of the usual troubleshooting. Using just one stick of memory in each DIMM slot, reseating CPU, only having CPU/memory/video card plugged in. I even went and bought some cheap RAM from a local retailer and the same thing, D bracket just hangs. Taking out battery, resetting CMOS switch, etc. This build has been very frustrating. I have read there are BIOS updates, but have never updated bios before. How would I do an update when the system won't even post? PLEASE HELP!!!

I got it to post and install windows on the Kingston valueram. I did a live update via MSI's website to BIOS version 1.2. But version 1.2 would still not post using my OCZ memory. I wanted to try to flash the beta 1.31 bios, ut I am having difficulty flashing the beta 1.31 bios version ins DOS mode. Has anyone else done this? Also, when is MSI going to put the newest bios version up for Live Update. That would make a lot of unsatisfied customers, happy. I was about ready to return my board and go ASUS. But I wanted to stick it out with MSI because I like you guys the best! Any info on flashing bios would be great! AMD

K9N Platinum SLI - Powering up the PCIe cards

Hey everyone,
I've got a K9N Platinum SLI board. This board has a power supply input point called PWR2, which according to the documentation is used to provide power to stable the operation of graphics cards. My graphic card is BFG nVidia 9750 GT. This card has the PCI-Express external power plug in the back, and my power supply has a dedicated (red) connector for this purpose, which I have attached properly.
The PWR2 is currently connected also, into one of the black 12V connectors. Otherwise, everything is running fine and smooth, but I am sometimes (once a day or so) experiencing random shutdowns during intense gaming (playing LotRO). Stress testing does not cause a shutdown: I've ran 3D Mark 2007 straight for 8-9 hours, while having a CPU Burner application toast the CPU at the same time. But no problems whatsoever. No other games exhibit this problem either.
Since I am providing dedicated power through the extra connector at the back of the card, should I leave the PWR2 connector unplugged ? Is there a chance that using these two connectors at the same time causes the 12V rail to overload, and the PSU shuts down to protect itself ? When this shut down occurs, the power LED is left blinking and I need to plug out the wall socket and wait for several minutes before the blinking stops and it starts up again.
My computer has an Enermax Liberty 620W power supply, and AMD Athlon X2 4600+ CPU. So there should be enough juice, at least. I've tried the tips and tricks suggested here. Using USB-connected Keyboard and Mouse does not correct the issue. I've also verified that this is not an overheating issue. My CPU is cooled by a Scythe Ninja tower heatsink and two 12 cm fans. It is possible that the northbride is heating up (it burns the finger on touch when under load), but from the Web, I've understood that the stock passive heatsink should be enough, and that the NB chip can take rather extreme temperatures.
* UPDATE *
Plugged the PWR2 connector out from the MB, and update the BIOS to 1.10. It's working as usual, but haven't ran any games yet. Heavy gaming usually reproduces the issue, so I'll write more when I know more.

Updated information on the case.
I've been running 2 days now with the PWR2 unplugged. I have had zero problems with shutdowns since. The only problem I now have is that the USB keyboard and mouse refuse to work in Windows XP after an initial bootup from powered down state. I have to unplug and replug them at the login screen in order to get them work again.
So, I decided to do a final sanity check, and replugged the PWR2, then went gaming. After 2 hours of playing, my computer shutted down for the first time. Plugging in the cable did not solve the USB problem either.
As of this day, I'm leaving it unplugged. It seems like an irrelevant connector, which just causes problems.
** Update **
After following Bosskiller's instructions on another thread about using the "Clear CMOS" button and then reconfiguring BIOS from scratch, the cold boot USB issues were solved. The USB devices now work straight after a cold boot, with no need to replug them.
I recommend that the PWR2 -connector info is added to the list of known problems in the sticky thread. If you have a GPU card which takes its power from a dedicated rail (and your PSU has a dedicated connector for this purpose), then leaving the PWR2 -connector unplugged might resolve your shutdown issues, like it solved mine.
After all, according to the manual, this connector is used to give more voltage to the PCI and PCIe busses, and some PCI/PCIe cards might not like this idea at all. There is a reason why these cards have an additional power plug on them...

K9N Platinum issues

I just bought an MSI K9N platinum mainboard with an AMD Athlon X2 4200+ cpu and Corsair Twin2X2048-5400C paired memory set. At first the bios would instantly crash but I solved that problem by by setting the voltage to 1.9v and manually setting the timing to 4-4-4-12 and forcing the clock to standard 667mhz (5400C is 675mhz). This allowed me to boot but both windows and windows setup would get a BSOD almost strait away (different one nearly every time). I then raised the voltage to 2.1v and this allowed me to log into windows but if I try to do anything stressful such as games or benchmarking it will run for a random amount of time (not usually longer than 5 minutes) and then get a BSOD. Occasionally background applications randomly crash and sometimes I get a BSOD for no reason in windows (not often). I ran memtest86 for 8.5 hours and it showed no errors. Ive updated the BIOS to the latest version. Any body have any idea whats wrong? I can usually use windows fairly fine but no games.

So this one will be fine? http://www.silverstonetek.com/products-65zf.htm
hope your right because thats a lot of money to spend if its not the problem. Is there a test or tell tale sign of low power so I can be sure?

"Artifacts and freezing on Sapphire X1900XT
Hello, I have a Sapphire X1900XT running at stock speeds and stock cooler. At default fan settings I have no problem running not so power hungry games but when I start Oblivion (1600x1200 2xAAA, 8xAF) the game runs good but about in 15 minutes (varies on the stressfulness of scene) the screen becomes garbled and computer stops responding. VPU recover sometimes manages to restart the card but it crashes again within seconds."

"I bought a Silverstone 650W Zeus and all problems are gone! No more weird fun speed changes under different loads, no more lockups!"
yep im sure its your PSU isnt enought. users confirm that, also official recommendation is "you need atleast 30A on +12V(450-Watt power supply or greater,30 Amps on 12 volt rail recommended) The power supply requirements for that card is 30 amps on a single 12v rail or 22amps on 2x12v rails(better get Sinlge Rail PSU, avoid dual rail)"
"Is there a test or tell tale sign of low power so I can be sure?"
-you can also borrow some recommended good brand powerfull enought PSU to test it before buy it, to be sure to resolve problem.
test you can see by yourself lockup, reboots, abnormal program termination,issues and other are expected when PSU isnt enought when your VGA starting to drain power. you can make test, decrease drasticly GPU Core and Memory Frequency and you must be stabilised.but that isnt solution it is just for testing.

K9N Platinum Ram Voltage??!
