P6N SLi F1.....inability to lock cpu multiplier

Hello
I have a system based on the P6N Sli-F1 Bios ver 2.3
2Gb Ocz Platinum pc6400
xfx 7600GT Fatal1ty
Hyper 530w psu
System runs fine and is faultless.
My problem seems to be getting the cpu to run at the speed I set it at. Even with "speedstep" manually disabled it lowers the multiplier under normal use and only speeds up when under load. Have an E4300, E4400 and a lovely E2160 which all have the same results.
Also.....Every time I set the BOOT order so that my HD is first and the rest disabled, upon re-entry to bios, boot order reverts back to having all boot devices in list.
Incidently I have run all 3 cpu's and run the usual benchmarks once a sweetspot is found.
Results conclude....E4400 MO stepping is crap compared to the baby E2160 which is only a couple of points short of my best result with the E4300 [3.4] on standard cooler.
All 3 cpu's stay set at their maximum on my sons Gigabyte GA-G31MX-S2 which is a lowly board in comparison.
Anyone any tips before I decide to buy another motherboard to try maybe the XFX MB-N650-IUL9 NF650i Ultra cos I dont need SLi

Isn't that a good thing? Are you experiencing any performance problems or lags?
The feature that is responsible for this behaviour is called C1E [Enhanced Halt State]. There is a hidden BIOS Option somewhere named "C1E-Support". Press F4 while you are in BIOS to make it visible. The default setting is AUTO or Enabled.
I am running a slightly overclocked system with C1E-Support enabled. In the last 12 month I have experienced no perfomance problems or lags. I kind of like the idea that the CPU is running at full speed only when it needs to. Also note, that the CPU multiplier is not the only thing that is automatically adjusted. VCore is decreased as well when system is IDLE. The helps to lower power consumption and keeps temperatures down a bit as well.

P6N SLI Platinum not booting after CPU change

I just upgraded the CPU in my machine with a P6N SLI Platinum motherboard from a E6700 to an E8500. I first upgraded the BIOS to 1.7 as the MSI page seemed to indicate that was a pre-req for this CPU. The machine was working fine for a day with the new CPU.
I changed the CPU in the machine and when I tried to boot, the lights on the motherboard came on as well as the fan, but no video or sound. In addition none of the diagnostic LEDs on the D Bracket light up. They had been previously working. Neither do the lights on my memory sticks light up.
I tried clearing the CMOS by hitting the switch but nothing. I am now going to try switching back CPUs but I don't have much hope that that is the problem given the diagnostic LEDs don't light. Does anyone have any suggestions as to a fix or is this motherboard fried?
P.S. Do you hit hte CMOS clear switch when the computer is off but the motherboard is charged? Or do you unplug the computer and wait for the internal orange light to go out as well too?

What is the QC number (by the cpu socket) is 01, 02, or 03?
See this thread for more:

Ah. Given I bought my P6N SLI Platinum 3.5 years ago when they first came out I imagine mine is one of the older versions that doesn't support 45nm CPUs by default. Is there a photo somewhere showing where the QC number is located exactly on this MB? It's probably located under my huge CPU heatsink and I'm not going to remove that for a third time just to check.
I really wish the MSI CPU compatibility page mentioned that. It would save me a lot of time. It's not worth my time and effort to dismantle my PC, send them the MB and wait for them to send me back a compatible one.
I verified the BIOS upgrade by looking at the version number at startup and using CPUZ.

P6N SLI Platinum random shutdowns

System:
MSI P6N SLI Platinum MoBo
Intel E6750 CPU
Etasis 850W PSU
Corsair CM2X1024-6400C4 RAM (using only 1 stick while troubleshooting)
MSI NX8600GTS GPU
OK, this is a strange one. I put my new system together and everything seemed to be working fine. POST looked OK, and I was even able to install Windows. Everything seemed stable.
One thing that troubled me was that the lights on the D-Bracket were all red AFTER POST. In other words everything was working, but the LEDs were showing CPU problem. I tried everything I could think of to get the lights to go away, but nothing worked. I disconnected all HDs, DVD, and floppy drives. I reset the BIOS, and reseated the CPU. I tried putting RAM in different slots, tried both sticks solo, but nothing made any difference.
It was getting late, so I decided to go to bed and run memtest86+ over night. When I got up this morning the system had powered itself down. When I turned it on again it powered itself off within a minute of being turned on. This was with all the drives hooked up, so I disconnected everything and now it's been sitting happily in the BIOS for over 30 minutes.
So at this point, it seems like it could be a power supply issue. Unfortunately, I don't have another PSU with an 8-pin CPU connector that I can try in this system. Any thoughts? Next steps to try?
Other possibly useful facts:
When I boot into the BIOS the D-Bracket lights show #3 green, and all others red, indicating "initializing keyboard controller". But when I boot past the BIOS to a CDROM or Windows, they show all red, indicating "CPU problem"
The system makes a brief chirp the POST screen. It doesn't sound like a beep code to me, and I've heard some boards will do an "everything's OK" beep like this. But it could be important so there it is.
Although it seems happier with all the drives disconnected (indicating a PSU problem), it still shows all red LEDs on the D-Bracket (indicating a CPU problem).
This is not the first system I've built, and I was fairly careful about putting everything together the right way. The only goof I know of is that at one point I was unplugging and re-plugging things and I ran the system for a while without connecting PCIE power to the GPU. Could that have broken something?
Any help would be much appreciated.
-Steve

UPDATE: I tried hooking up my old 400W PSU with 20-pin ATX and 4-pin CPU connectors (apparently this is OK to do) but there was no change. Still four red LEDs.
I also tried removing the PCI-E GPU and booted it up with an antique PCI VGA card. Again, no change. Maybe I really did get a bad CPU?
Any other ideas, before I try to return my CPU?

P6N SLI Platinum

I recently built a new computer with the P6N SLI Platinum mobo. The cpu (Intel Duo 2 Core E4300), vid card (evga 8800 GTS), memory (mushkin 2gbddr2 800), hd (Maxtor 320 gig SATA), and psu (apevia atx 500 watt) are all new. When the computer boots, all the fans and leds come on, but the monitor doesn't get a signal and the screen is black. I reseated the vid card and tried dvi/vga adaptor and a different monitor. The orange light and green light on the mobo are on. I used the pcie power 6 pin plug for the vid card. The 24 pin and 4 pin power connections to the mobo are ok. I haven't seen the bios because of the black screen. I also cleared the cmos and still no signal. I also tried an old Voodoo 2 pci vid card without the 2d pass through option and still no signal (don't know if that would work any way, but worth a try). The optical drives and the hd spin so they seem ok. I installed the D bracket with the lights to the usb header and jdb header. Should I see lights on this D bracket when the computer is booting? I don't see any and I don't get any beeps.

I now have no lights on the D bracket after clearing cmos again. I tried booting with one stick of ram and no change, then I tried booting with no ram and no change (no D bracket lights and no beeps). At this point, I have very little plugged into mobo - 1 hd, two optical drives, cpu, 2 fans and that's it.

P6N SLI Platinum - E4300 multiplier drops to 6x

Hi all, first post. Did some searches on here and can't find an answer, also this is a pretty new mobo.
CPU-Z shows my cpu at 1.8ghz @ 9x multiplier, but every few seconds it switches to 1.2ghz @ 6x multiplier. This sounds like a speedstep issue, but I disabled EIST in the BIOS, and all spread spectrum options. In windows power management I set it to Always On. I see a lot of talk about C1E but don't see any option regarding that setting in my BIOS.
Is this normal behavior for the E4300? I'm hesitant to start OC'ing when I'm having issues at stock clock.
Thanks for any ideas.
My setup:
P6N SLI Platinum / E4300 / Scythe Ninja / Antec Trio 650 / 2x1 GB Corsair XMS2 6400 / 2x WD 160gb - RAID 0 / Leadtek 8800gts 640

Quote from: Maesus on 06-March-07, 09:06:11
how about locking it to 6x and ramp up the FSB much higher?
Would there be an advantage to that versus a 333fsb x9 (3ghz) OC? I didn't get the best ram in the world because I wasn't looking for crazy speeds. The PC-6400 Corsair ($160 w/rebate) I have is rated at 5-5-5-18 at 1.8v. I have it at 5-5-5-12-2T at 1.9v. I'm not uber-conversant on memory timings but when I set it on 1T windows crashed immediately. Anandtech mentioned that changing to 1T had little to no real world performance improvements so I can live with it.
Currently I have the fsb at 333 (1333 in BIOS setting) and DRAM at 333 (666 in BIOS) so I have a 1:1 ratio which I understand is preferable. The MSI Dual Core utility reports that my CPU is running about 7 degrees cooler than the System temperature. Is that possible, or do I have a jumper setting mixed up somewhere...

P6N Sli Platinum front audio panel and CPU temp voltage issues

Hi All,
I got my P6N Sli Platinum yesterday, build up my computer without any major issues. However I have noticed that my audio front panel does not work. It could not detect my microphone when i plug it into front auido panel, it works fine for the rear auido panel though.
Another issues is I highly doubt the accuracy of CPU temp sensor. Msi 's software monitor reports my CPU temp is around 19-20 degree, I know that's too good to be true even I am using a water cooling system. Btw my cpu is E6600. Anyone else has the similar issues?
The third, I notice my CPU voltage is bouncing between 1.1 to 1.24 in CPU-z. And the multiplier is changing from 6 to 9, frequency is changing from 1.6g to 2.4g. I only see this in CPU-z. Msi 's own software reports CPU running at 2.4g though. Is this cpuz issue or something else?
Finally, any tips to max the overclock potential of this board? I have overclocked to 3.1g but there are some crashes. Going higher the board just won't boot up. I read a review on anandtech.com says 1.22 bios is good for oc. Where can i download that? I only found 1.1 bios on official site.
Any reply will be appreciated.
Cheers

C2D-CPUs have a digital internal sensor to monitor CPU Core temperatures. Have a look at those with Core Temp ( http://www.thecoolest.zerobrains.com/CoreTemp/ ). This Tool reads the temperature data directly from the register of your CPU. There is nothing wrong with the sensor. It is rather the MSI tool that does not read the data it provides correctly.

There is no issue. What CPU-Z allows you to see there is the C1E-feature of your CPU at work. When there is nothing to do your processor will automatically reduce Core Voltages and frequency to save power and keep temperatures down. As soon as the work load increases the multiplier is set back to x9 and core voltages increase dynamically. It is meant to be a good thing.
I have overclocked my system a little and I like that the C1E feature is still working at this speed setting CPU frequency to 2GHz and core voltage to 1.144v when my system is idle.
If you have problems with this feature you can turn it off in BIOS. The option is labeled as "C1E Support" and might be hidden somewhere. You may be able to hit "F4" to unhide it.
The MSI utilities are not the best tools to monitor your system. CPU-Z, Core Temp, Everest, Speedfan, Memset, Rightmark Memory Analyzer for example do a far better job.

P6N SLI CPU voltage options

hi all
I have checked the other P6N SLI posts for this but i was unable to find it. no doubt someone will point me to one but i will ask anyway.
In the cell menu the option for voltage for the CPU is a little confusing to me. My previous asus motherboard had simple voltage settings going up in 0.250v sections, like
1.250v
1.275v
1.300v
they were alot more accurate and smaller but i hope you get my idea.
In my P6N SLI menu, it only gives options like 0.125v and upwards to around 0.300v
I do not get what voltage is what for my CPU. As my CPU is a E6550 its highest voltage is 1.5, how can i know what to select if i were to overclock the thing?
thanks for anyone who understands.
Dan

oh right, so how do i find what my default VID voltage of my CPU is ?
Intel lists it as
VID Voltage Range: 0.85V – 1.5V
You can get the VID by downloading and running Core-Temp. You can leave the CPU voltage at "auto" and the MB will adjust for the correct CPU voltage..you can see approx CPU voltage in bios, under Hardware Monitoring.

A88XM GAMING v1.5 BIOS CPU Multiplier Locked?

Since I updated to the latest v1.5 BIOS the CPU multiplier seems to be locked. Is this intended or an issue with BIOS, or am I just doing something wrong? The multiplier worked fine on v1.4. I am using an AMD Athlon 760k CPU. Thanks.

I cleared CMOS and it's working now, it's something I really should have done in the first place Thanks

Question regarding P6N SLI Platinum CPU support?

I went to the product page list on the main MSI website and it lists the Kentsfield CPUs, but I happen to have an Intel Yorkfield Q9450 CPU. The question is, will this motherboard support that CPU or will it only support the ones listed on the product page?
I have the P6N SLI Platinum mainboard and recently got my hands on the Q9450 chip and would like to swap out CPUs with the Core 2 Duo E6700 that is in there now - anyone know if I can or not? The product page says that a CPU with a FSB of 1333 has to have that set manually in the BIOS, which I am willing to do, just need to know if this mainboard will even support the CPU I want to put into it.
Thanks!

Nuts, that's what I was afraid of...I was thinking that since the product page specifies a CPU with a FSB of 1333 (which the Q9450 has) it would be compatible.
Thanks for the answers - looks like I can't re-use my mobo, time for a new one.

Conflicting info on Pentium D 930 cpu-P6N SLI Platinum mobo compatability

I have seen conflicting information on the compatibility of the Pentium D 930 CPU and the P6N SLi Platinum motherboard (MS-7350 Ver. 1). On MSI's website I have searched for this motherboard and then gone to the compatible CPUs. Several Pentium D models are supported, however 930 is not among them. In searching on this site I have spotted at least one user who seems to have used these two together successfully.
https://forum-en.msi.com/index.php?topic=116011.msg872815
it appears that this user was using the bios update version 1.5 originally and then upgraded to 1.6. Both appeared to work for him.
I was hoping to find out if anybody else has an opinion as to the suitability of this combination? From the physical evidence, it would appear that this works. Is this perhaps just a situation where MSI didn't bother to update their CPU compatibility list as bios versions evolved?

Well, seems some Presler cpus are supported so it could work. So far I don't see any technical reason why it shouldn't. None the less there is no official support since it is not mentioned in the cpu support chart. Either it will work with no problem or not boot at all. You can do no harm to it trying. If it works the post screen could show unkown processor because of lacking support but if you get that far everything will work fine.
With the other user having it work there should be no problem. Just try it as I guess you have an old 930 lying around (you don't want to buy such an old cpu or do you?).

P6n sli and e6700 3.2 ghz cpu problem

hello. my mobo is p6n sli (ms-7350 model).. i changed my old cpu(e4400) with new one(e6700 3.2 ghz). but i didnt get any visual from monitor. the thing is i checked mobo' s cpu support list and e6700 is there but it s an old model with 2.66 ghz. but mine is 3.2 ghz. what can i do now?

Quote from: Henry on 17-February-12, 08:52:44
Simple fact is the P6N SLI does not support the newer 45nm CPUs. The e6700 2.66 GHz is 65nm, the e6700 3.2 GHz is 45nm. There is nearly a 4 year difference between the 2 and technology moves on and leaves the old stuff behind. What's unfair about that?
Try and get your hands on a good P45 Platinum MB if you can find one. Much better than your NVIDIA chipset MB anyway.
According to this: http://us.msi.com/product/mb/P6N-SLI.html#/?div=CPUSupport
some 45nm CPUs are supported such as e5200, e5300, and e5400
Simple update in CPU micro code would fix the problem

MSI P6N SLI V2 CPU Heatsink Q

Hi,
I have a quick question about compatible heatsinks for this board (MSI P6N SLI V2). I've been looking at a few and have decided to go for the Zalman CNPS9500A-LED (I'm pretty sure it'll fit) does anybody have one of these fitted?? I did read on another forum that there might be a problem with the underside of the board, but it wasn't very clear which board they were refering to....
Any help would be great...... Many Thanks

I suggest you also ask Zalman directly: http://www.zalman.com/ENG/Contact/GetSupport/Write_Form.asp

Update on Pentium D 930 + MSI P6N SLi Mobo

A short time ago I was searching this forum for information concerning the compatibility of the Pentium D 930 processor with the MSI P6N Sli Mobo. It seems that this processor was not officially supported for this board. A few helpful people offered the opinion that they would likely work just fine together. I just wanted to get back to you guys and say thank you again, that turned out to be exactly the case. :D
After an embarrassing no-post situation caused by the leftover mounting spacers from my old board (which used 12) to my present board (which uses 9), everything went smoothly. Acronis with Universal restore allowed me to regenerate my operating system. After a lengthy update of drivers the computer was up and running smoothly and with a entirely welcome but somewhat puzzling difference. Whereas the old board (D945PVS) consistently provided an environment in which the CPU ran at 50°+ C (?!) and had transient temperatures as high as 58 - 59° C with an ambient 20° C, the new set up consistently ran below 40°. These results were consistent no matter what type of thermal pastes were used, be they my homebrewed colloidal silver in silicone stopco*k grease or Arctic Silver. (that's hilarious... the anti-obscenity software interpreted a fully normal English language word as obscenity)
Well, whatever the reason....sweet.
I have only attempted simpleminded overclocking as the options are somewhat limited by the processor. With the frequency for the GPU locked at 100 MHz, simply adjusting the FSB to 1000 raised the apparent speed of the CPU to 3.75 GHz, up from the stock frequency of 3 GHz. An attempt to set the front side bus at 1060 resulted in a non-bootable system so back to 1000 it went.
I have not adjusted any of the system voltages. So far I have not stress tested this other than to simply use the computer for several hours. No apparent problems yet. The system temperatures have remained between 38 and 40° C in an ambient 20°C environment.
The only thing that nags at me, and I'm fairly sure that this is of no importance is the fact that in device manager the CPUs show yellow exclamation marks and in properties I see a message saying that certain drivers failed to load for the CPU and that other software may be taking their place. Well, whatever this actually means, it has had no detectable impact on system performance or reliability.

Hiya flobelix
If by manually updating the drivers you mean by left clicking on them in device manager and selecting update --> search online, then yes, I did. I do not have the exact verbiage but the resultant error message was something to the effect that the drivers had installed but failed to start and something else may be taking their place.
Driver magician fails to detect that any cpu drivers are missing. Same with online testing services such as PC pitstop. | have done a cursory search using Google to find people with similar problems but I have not as of yet seen this EXACT problem.

Hello welcome to the forum,
It's just a warning, totally ignore it.
Your CPU changing speeds is a result of Intel EIST, or Speedstep it's more commonly known as. It default multiplier and drops voltage when CPU is idle.
Get ORTHOS from here, does speed go back to 2.13GHz?

P6n sli platinum + e4300 oc

I've read tons of posts on forums, but most just give FSB speeds, not actual numbers to use in setting the system clock, so how do we know what to use actually?
When do you use the 1:1 ratio? or any of the others if your motherboard BIOS doesn't let you manually set your memory multiplier?

System clock I believe is how the memory freq is generated. "Auto" would be automatic, "Linked" would be linked to FSB speed, "Manual" wold be manually setting the speed.
65c on the cores or the CPU? Because if it's the cores, drop down, anywhere over 60c and your CPU may start skipping cycles.

CPU ratio is the multiplier in which you times the FSB speed to generate/set the CPU clock. E.g:
Code: [Select]
FSB of 100x10 (cpu ratio) = 1000MHz CPU core speed.

They are fine, just don't go over 2.3v, your RAM chips will start to fry otherwise.

No, wrong way to do it. Do it like CPU VCore, only increase when stability is needed. Also monitor temperatures of NB as much as your CPU. Fan speeds don't bother me either, but temps do! Watch them at all times when overclocking.

Only increase if you need to, the SB core is usually the last voltage that needs increasing.

It's the voltage you supply to the FSB bus, too much and you will kill the FSB and your mainboard will be a fancy paper weight. Only increase when stability is needed, just like every other voltage.
