P55-GD65 Voltage Discrepancy

Why is the voltage variance of this board so high? With low Vdroop enabled on a voltage of lets say 1.36 in the bios I get a 1.40v reading in CPU Z @ idle. This turns into 1.42 or more under load. Am I missing a setting that will keep it closer to what I set it at? This variance is rather ridiculous if you ask me. I have all the standard power saving features turned off before anyone asks.
Thanks!
My System:
Mobo: MSI P55-GD65
CPU: Intel i5 750
GPU: Ati 4870x2 2 GB
Mem: 2X 2 GB G.Skills Ripjaws DDR3 1600
SSD: OCZ Agility 60 GB
HD: 2x WD Black 500gb ea Raid 0
PSU: PC P&C Silencer 750

Songokussm the same issues I reported to support, they responded to me, that my MB is faulty and I should RMA ( did it twice, 4 month without MB ) I prove them otherwise, I had 3MB P55-GD65 with the same issues. Short speaking every MB with ERP=040 is faulty on engineering level Overvoltage like you described, problems with fans on sysfan1 and sysfan2, restore AC on power loss not working correctly and sometimes USB2 stops responding.
My conversation with MSI support ended when they statement that they can`t check if I`m correct because they don`t have MB with ERP=040, so the problem is .... gone I bet that with bios 1.9 in your case issue still occur but is`t less "visible".

BIOS doesn't change CPU Voltage P55-GD65

I have a P55-GD65 with BIOS Ver 1.7
No matter what setting I put the the CPU voltage it seems to run in auto only. I have tried many combination's of settings that I have read on the forums but nothing seems to be working.
Has anybody had this problem?
Thanks,
Mark

Yes even when I have Intel C-STATE and Intel EIST disabled.
The voltage is much lower. I can't over clock because I cannot up the CPU voltage. I have the CPU multiplier at 21 and the clock at 155. If I go even up to 156 on the clock my system will blue screen.
When I put the voltage in Auto and monitor it and then put it in manual and crank it up to 1.45 and monitor it the voltage behaves as it is in auto. I have XMS 1600 memory and the Mugen B rev 2 cooler so I know that is not an issue. I might have a defective MB. I've been building PC's for years so I'm not a newbe. I've usually used Supermicro boards and this is my first MSI board. The board is very nice and if it worked it would be great. I was going to build another system with that board but am a little gun shy now.
Thanks for all your help.

Problem with sound in p55 gd65

hello
i have a problem in my system and i dont know its from mainbord or other devices
when i playing game or watching movie,suddenly the sound is cutting down(stoping) and cpu usage going up(25 or 30 %)
in game i had no sound and game play was with tik and also in watchig film
this problem is not always happend but im comfused
main msi p55 gd65,cpu intel core i5 2.66 ghz,ram 4gb ocz 1033,graphic ati 5770 sapphire,power icute 950w,hdd WD 1tb

Use MSI Afterburner and set lower or fixed clocks for the graphics card.Enable Unofficial OVerclocking and set a fixed 2D clock to be applyed at start up ,see what happens.
Play a little with the 2D/3D clocks.I ve saw somewhere on a forum a issue with a similar mobo from some other vendor and another video card.The problems of that user stopped when he lowered the clocks of the video card.
You are using a 5770 which does a lot of frequency/voltage switching while in desktop.

Is my P55-GD65 dead on arrival? No response at all.

I'm not getting anything out of my new board. I've built many systems before, but this doesn't seem to be working right. I've got:
- power supply connected at both the main power connector and the 8-pin aux power connector
- CPU installed with fan plugged in
- 2 DIMS of RAM installed
- video card installed with PCI power plugged in
- no front panel connections
- board is sitting on my table, not in the case
When I flip on the power switch on the PS, I don't get any LEDs on the board lighting up. I couldn't find anything in the manual about a power LED except for the 6 CPU voltage phase LEDs across the top of the board, but I don't know if those should be lit without the machine fully on or not.
Should the power and OC'ing buttons at the bottom be backlit when the machine is off? Shouldn't I be able to use the power button on the board to power up the machine without the front-panel switch? I get no fans or drives spinning. Should I be getting any voltage readings from the test pins when the machine is off, or only when running?
I tried my old power supply with the same results.
I'm guessing the board will need to be returned, but I just wanted to get a second opinion.

Thanks for the replies.
Before I pulled the board out of the case to test it on my table, I did try powering up the system from the front panel power button. When that didn't work, I removed the board from the case in the event the board was shorting out in the case.
I'm assuming that the power button on the board itself should work to turn the system on instead of shorting the pins for the front panel button.
So, on the P55-GD65 specifically, should there be any LEDs lit on the board when the PSU is on, but the computer is powered off?
Thanks

[WTA] MSI P55-GD65 6 phase on all the time? Where's APS?

Hello, First Post here..
I bought a MSI P55-GD65 lately and it runs spectacular and overclocks nicely. the newer BIOS 1.6 is noticably more stable when High VDroop is used than the BIOS 1.5, resulting in more power-efficient system of my own despite overclocking .
But nonetheless, i have some issues i would like to be answered:
1. When I use BIOS 1.5, the core voltage would be dropped to 0.896 (CPU-Z) when i set the core voltage as auto and all the power saving features enabled (C1E & EIST Enabled, C6 state selected, Turbo Mode off). but when i flash into BIOS 1.6, the same setting does not result in decreased voltage, the core clock still slows down though like it used to be. Maybe the next revision of BIOS will fix it?
2. I searched this forum about APS on P55-GD65, i have found that somebody here had testified that the BIOS 1.6 fixes the all-phase-working problem, as i was having the same problem too. Then i decided to flash to 1.6 too (which work flawlessly with your USB Flasher by the way, kudos ). But the problem still persists. APS only works when i apply through Control Center. i wonder about APS statement of "will work regardless of operating system" is a true and automated one. And yeah, i have tried to clear CMOS and run it on nominal mode and still no changes from BIOS 1.5. The 6 phase LED is lit all the time unless i "apply" in Control Center.
My Current system are:
MSI P55-GD65 (Lotes ILM)
I5 750
HD 5770
Silverstone Zeus 750Watt
WDC Black 500GB
Windows 7 Ultimate
Thanks for your attention.

Quote from: chrisjb on 19-January-10, 17:13:56
you have to run the cpu at default settings so (133mhz X multiplier) the slight overclock of the cpu will disable power saving so all the phase leds will constantly be lit up.
Have the multiplier running at 160 because of XPM 1600 memory blocks, and the board runs with 2/3 phases in normal mode.
Are using BIOS 1.3 because of XPM problems with other versions.

P55-GD65 BSOD Issues, Help very much appreciated!

Hi Guys,
I recently bought a new PC with a P55-GD65 motherboard and Im getting a lot of blue screens.
I started a topic on SevenForums and attached all dump files but it seems the problem is hard to pin down.
The topic and dump files can be found here: http://www.sevenforums.com/crashes-debugging/48197-please-help-bsod-new-windows-7-x64-pc.html
Im using the latest BIOS (1.5), Im running Windows 7 x64 Home Premium with latest updates and Im using the latest MSI drivers for the Motherboard.
The only software installed is:
- Eve Online client
- Steam and Modern Warfare 2
- Teamspeak RC2
- MS Security Essentials
- PC Angel (revovery software)
On SevenForums I was advised to check my harddrives, I runned HD Tune and my drives showed no errors.
I was also advised to run memtest, Im running it for over 4.5 hours now without any errors.
I realy dont know what I can do anymore. Do you guys have any advise what else I can try?
I have changed nothing in the BIOS itself and Im not overclocking the system.
Should I manually adjust some settings maybe?
Below is my hardware configuration:
CPU: Intel Core i7-860 2899 1156

P55-GD65 Problem Freezes / Shuts Down unexpextedly

Hi all,
I've recently received a replacement P55-GD65 part for my pc upgrade. The first mobo was broken but I'm not sure wether the current one is any better.
I have a freezing problem with my set up. After I power up it goes to post and lauches windows. However, within 5 to 10 minutes the system just shuts down on its own. Sometimes this happens already in BIOS when I've been looking around for a solution for some time.
After power down pressing the power button doesn't help. I have to disconnect power cord from PSU and wait a bit before reconnecting for the power button to work again.
I've been reading other posts and people have the similar problems, but none of the solutions have resolved my problem.
I've tried putting OC genie on - no solution.
I've tried using only 1 memory - no solution. and yes I've taken the memories out and reincerted them.
I've tried setting BIOS to optimized defaults - no solution.
I've tried setting memory speed down from Geil automatic 1333MHz to 1060MHz - no solution.
I've tried setting memory voltage up from Geil automatic 1,5V to 1,6V - no solution.
I've tried taking CPU out and replaced it in the socket - no solution.
I've updated Intel drivers from MSI website.
I've updated other drivers from the CD that came with the mobo.
BIOS version is 1.3
There has been a lot of discussion about corsair memory modules but none about the GEIL ones I have. Has anyone experience with the memory I have? According to MSI website P55-GD65 is tested with a dual setup of 2g Geil memory that I have, and should be ok.
Can anyone lend a hand so that I can get my pc running. This has by far been the most troublesome upgrade for me.
Thanks for replies!

TheManitee, 1st you hijack this thread demanding help and you don't even have the same MB & other parts. Please start your own new topic instead of hijacking another persons. >> Please read and comply with the Forum Rules << >> Posting Guide <<
To me it looks like not a single one of you has bothered to up date BIOS which has over time had numerous memory compatibility fixes.
Update BIOS, get Crucial RAM.
>> Use the MSI HQ Forum USB flasher <<
I am not able to update the bios because my pc would crash before allowing me to. I asked MSI to update the BIOS before sending the board to me.

Nothing than troubles with this one.this is my first MSI board and it will be my last MSI board nothing then troubles with it
When i remove the webcam from the system the PC starts automatic again.
When i unmarked automatic reboot then i get this fault "USBPORT.SYS"(blue screen)
When i do the same with usb stick it works fine,i have this problem only with the web cam and in all the usb ports
And it is only in Win xp and the fault is not when i unplug the webcam in win7.

I send the modules back to the shop on RMA before I read the above suggestions. Hope you do not mind guys!
My opinion at the moment is that I have done a whole lot to make these modules work, more than you can expect from a customer. As far as this goes, I believe the modules should be able to run at standard settings (timings, voltage, etc) on any motherboard. I am not interested where the responsibility lies for the manufacturers of either hardware, but the whole thing seems to be lacking standardization (if at all possible with this kind of hardware). Maybe I am to narrow minded in this, but that’s the reason I send them back. Apart from being a hardware and computer enthusiast, I am also still a customer with certain expectations.
It looks like the shop agreed because, after receiving the modules via the RMA procedure they replied (translated from dutch):
Quote
Dear xxxx
We have tested your returned product(s). The results from our test indicate that the product is indeed faulty.
We will contact you as soon as possible to discuss further steps.
Since the receipt notification (of receiving the package I send) and the notification above were only 1 minute apart, I have reason to believe that they did not test the modules at all (or did not care what the result is).
I do wish to express my gratitude for your help, without your help I could not have come this far! Thanks!
@utgamer2004: I hope your RMA will be granted as well, my experience may be positive but this will depend on the shop or the manufacturer.

P55-gd65 memory

Hello,
I have a msi p55 gd65 i5 board and want to buy kingston KHX1333C7D3K2/4G memory. Does anybody know of this will work well?

Quote from: ZSDE on 13-January-10, 01:27:16
Further Edit: On the Kingston site it states: HyperX DDR3* features: 1.7v - 1.95v voltage range for dual-channel applications for AMD based systems and Intel chipsets older than X58. So, yes, that mem is meant for AMD boards.
That fits AMD board but also "X" suffix designates XMP ready for Intel Core i5 7xx and Core i7 8xxx series processors and systems
"Each module kit has been tested to run at DDR3-1333MHz at a low latency timing of 7-7-7-20 at 1.7V.
The SPDs are programmed to JEDEC standard latency DDR3-1333MHz timing of 9-9-9 at 1.5V"

What is your current BIOS Version?
Please run a test with the following setting:
-> Disable XMP in BIOS Setup (if enabled) and ensure that the memory speed is set to DDR3-1333 for now (and not one bit more)
-> Manually set the DRAM Voltage to ~1.575V
-> Manually set the Memory Command Rate to 2T/2N
-> Disable Spread Spectrum

MSI P55 GD65 Booting issue [SOLVED]

Hello everyone!
I finished a new build two days ago:
Intel i5-750, 2.66GHz
MSI P55-GD65, rev. 1.0, BIOS 1.3, Lotes socket
A-DATA 2x2GB DDR3 1600Mhz CL8 Vitesta Extreme Edition
GIGABYTE ATi R5850 1GB
KINGSTON V-series SSD 64GB SATA
SAMSUNG SpinPoint F3 500GB SATA 7200rpm
Artic Cooling Fusion 550, 550W, dc outputs are mentioned below
and some minor components (optical drives, wifi card etc.)
I started the computer and everything seemed fine. I managed to enter the bios. I was checking H/W monitor and several other options, I didn't change anything. Suddenly (after circa 5mins) the computer shut down and started to turning on and off repeatedly. I stopped the loop by turning off the power supply. I started it again, however it got stuck in the loop imediately. After a while I managed to access the bios again, meanwhile I was trying to find some answers on internet.
I decided to remove all memory sticks (as a lot of topics here in forum which are describing the very same problem sign RAM problem) and started computer. I expected beeps and LED-show. However, the computer didn't start at all! Even fans were not spinning, just nothing (although PSU was giving tension). I put RAM back and computer started. It was like black magic. I tried again, remove RAM - no start, put RAM back - no start too. Mobo went definitely dead. So I RMAed it.
I've obtained a new one, which was:
MSI P55-GD65, rev. 1.0, BIOS 1.2, Foxconn socket
I put all the stuff together and started computer. Everything went fine, I managed to enter the bios. Nevertheless, I decided to check RAMs for sure; I changed booting devices, restarted and booted system rescue cd with some utils. I started memcheck basic test. The basic test was fine with no errors, then I started filling with random pattern test. It ran for almost 24h. I wanted to try another exercise test and... computer shut down and the loop was there once AGAIN!
I don't think the mobo is the issue here anymore. I bet on two things: PSU or RAM (I'm not going to think about CPU!)
I don't recall exact dc ouputs but: AC Fusion has 2 12V rails with 17A each. Mobo needs 18A, but as I understand it, I have to check 2 rails combined against the requirement - 34A > 18A, it's okay, isn't it? I've choosen this one as I wanted silent PSU (it performed really good in tests, f.e.: http://www.anandtech.com/casecoolingpsus/showdoc.aspx?i=3516). I don't have any other similar PSU to swap (neither my friends).
My suspicion is the problem is RAM incompatibility. My RAMs (AD31600E002GU2K) have 1.65-1.8V working voltage. Maybe the mobo sets auto settings badly (I'm not present at my computer now, I left for the weekend); they are not in QVL too (http://eu.msi.com/uploads/test_report/TR10_1846.pdf). The problem is I was not able to get into bios before I left. As I read on the internet, P55 is pretty touchy when it comes to RAM. I'm thinking about swapping them for Kingston 2x2GB 1333MHz DDR3 CL7 (http://www.valueram.com/datasheets/KHX1333C7D3K2_4GX.pdf; which are not in QVL either, but KHX1333C8D3K2_4GX are; only latency difference).
Any advices on the whole problem?
P.S.: I've tried CMOS clear on the former one too, no change. As I mention I went through the most of the gd65 booting issues posts here on MSI forum and several others.

Do you think Corsair VX550 550W could do the job? It has a single rail with 41A on 12V. ATi certified Straightpower BQT E6-550W for 5850, which has 4 rails per 18A, but overall 41A too (http://www.be-quiet.net/be-quiet.net/data/media/_stories/216/sp_e6_550_EN.pdf).

Recommended memory settings in P55-GD65 BIOS

Hi All,
I was having all kind of BSOD problems with OCZ (OCZ3G1333LV4GK) memory on the P55-GD65 motherboard.
All problems seems to be solved by manually setting the DRAM voltage to 1.65v in the BIOS.
The rest of the settings is still on auto. Will it be good to manually adjust these also, for performance and a stability?
If so, what settings I have to make?

Thanks for the reply.
The BIOS shows the modules are running at 1333.
The Weird thing is I had many BSOD problems before I changed the voltage and on SevenForums I was advised to run Run Memtest86+.
I runned Memtest86+ run a few times for over 8 hours and it showed no errors at all.
I will make the screenshots asap when I get home tonoght. Below are my system specs:

MSI P55-GD65 + Corsair XMS3 CM3X2G1333C9 = Random freezes,buzzes,reboots..

Hello..
My system specs are:
Mobo: MSI P55-GD65
CPU: Intel Core i7-860 (with Megahalems heatsink)
RAM: 2x 2x2GB (dual channel = 8GB in total) Corsair XMS3 CM3X2G1333C9
GPU: ATI HD5770
PSU: Corsair HX520W
The problem I face, is that I get random freezes (sometimes this is accompanied by a loud buzzzzzzzzzzzzzzz coming out of my speakers), or cold reboots. It's not something that is triggered by some specific action (e.g when I run a specific application or something like that), sometimes there are days that I don't get a single reboot, and other days that I get 4-5 freezes one after another..
I read in another forum, that this specific series of motherboards (GDxx) have some trouble dealing with certain memory brands, especially corsair. I don't know if that's true, just throwing it out there if someone has any similar experience to share..
So far I've tested my memory with memtest (overnight 8 hour test, it completed a few cycles), I've tested my cpu with a several hour prime95 small FFT test, which stressed my CPU in 100% for a few hours but that didn't trigger a freeze or a reboot. My temps are perfectly nice and normal..
Reading from Everest, I still use the AMI v1.0 version of the BIOS, but I don't tend to update things that work (there were a couple of times in the past that this only made things worse). I have set my bios settings to auto, do I don't know if I should play around with anything there, I must say though I've always been a bit skeptical about changing voltages or something (never played with overclocking in my whole life), fearing that I could damage anything, or at least lower its "expiration date"..
I hope someone expert can help me out..
PS. I must say this mobo is the second one I got, my first GD65 was replaced, but it had nothing to do with similar issues, I accidentally damaged the cpu socket. I can't seem to recall though, if I had such problems with my first mobo too..

As gcanuck mentioned, in BIOS Cell Menu, Spread Spectrum should be disabled. If not done so, test each RAM stick individually in the primary black dimm slot. DRAM V. maximum is 1.65v's. It also may be that the CPU IMC refuses to cooperate. With only two sticks in the black slots, does this freeze problem continue? Another possibility is that the two RAM kits are of different chips even though they have the same specs. Are the batch numbers the same? Some may have Elpida chips, & the other kit Samsung.

Although another guy in another topic suggested even higher voltages, up to 1.79V (!!!!)
Whoever advised that is a moronic idiot!

P55 GD65 - Advice

When I first installed new system, everything was running fine. Enabled XMP in bios and memory was running stable at proper timings and voltage.
Unrelated to the memory, I was having problems with the nvlddmkm error, where the screen goes black for a second followed by the message “nvlddmkm.sys has recovered from an error”. Somehow I was able to get rid of that problem but it was replaced by the same symptom, being caused by a services.exe login.
Anyway both of these events cause the video card memory controller load to spike to 100% and stay there until the system is restarted. Video card people said to update bios and see what happens.
So, after updating bios, (from 1.2 to 1.7) system is fine at auto settings (9-9-9-24-2t). If I enable XMP, I get two or three restarts…system stays on, but no video.
I’m just an old guy doing cadd work, looking for a stable system.
Anyone know what version bios for this board allows XMP to work?
If anyone has any suggestions on the nvlddmkm or services.exe login I will take those too.
Thanks

You could try to raise the CPU VTT voltage a little.

P55-GD65 - Available RAM Suddently Changed

Sorry for double posting this, but I figure I shouldn't have hijacked the thread I originally posted this in.
My problem can best be described as a sudden unexpected change in the available RAM. I have 2x2GB sticks that had previously been recognized at 4GB available, but this morning my machine will only POST with 2GB available. Both sticks are recognized and I can view SPD info, but during POST, only 2GB is reported.
I built my machine about 3 weeks ago and everything was working great, booted first try and no errors in memtest+ or LinX or Prime95. I have been running just fine since then. I have MSI P55-GD65, Core i5 750, DDR3 2x2GB GSkill Trident 2000MHz RAM.
This past weekend I decided to mildly overclock, I upped the bclk to 160 and adjusted the DIMM voltage to 1.6 according to the RAM spec. I tested and tested this config and everything seemed stable. I have been using the machine to play games and things with no problems.
I go to resume from hibernate this morning and the machine hangs. I restart and I notice BIOS is only showing 2GB during POST. I check out the BIOS settings and it sees the 2 DIMMS, but still only shows 2GB. I boot into Windows 7 x64 and it shows 4GB (2GB Useable). Previously all 4GB were recognized and useable just fine. This may be relevant, I don't know, but I started a long video transcoding job before bed last night. Presumably this job finished and the machine went into hibernate.
I reset all settings back to default, thinking maybe my overclock wasn't as stable as I thought, but no change. Even before I reset the clocks, I tried upping the DIMM voltage, the VTT voltage, reducing RAM frequency. Nothing.
I figure maybe I need to upgrade the BIOS, as I am currently running v1.5 and latest is 1.8. I download the 1.8 image to a flash drive and try to use M-Flash to boot the BIOS image off the drive, but BIOS hangs with a repeating BEEP when I try that.
Then I noticed something very odd. When I boot up with the flash drive plugged into a USB port, BIOS reports 4GB on POST. Without the drive, 2GB on POST.
As an absolute last resort I will reseat the CPU, but after the flash drive behaviour, I am not sure it is a CPU pin-contact issue. When I get home from work I am going to flash to v1.8 BIOS and see if that helps. If not, I will reseat all DIMMS and try that. If the problem persists, I will try DIMMS individually and in different slots and see. I will also try a CMOS clear, before and after the BIOS update.
Is there anything else I should try before reseating the CPU? What if I just wiggle the heatsink? If it all possible, I would like to avoid having to clean up the TIM and reapply, it was a big pain on my heatsink.
Thanks,

Intel Core i5 750 @ 2.66GHz
CM Hyper 212+ HSF
GSkill Trident 2x2GB DDR3 2000 - F3-16000CL9D-4GBTD (Running @ 1333MHz 9-9-9-24)

Corsair CMPSU-750TX 750W
Sapphire Radeon 5850 1GB

Have been monitoring very closely and the issue has not cropped up again.
I have been running everything at stock since the incident. As I am really not sure what caused the problem, I am a little hesitant to overclock again. Though I do want to get more performance from my RAM and CPU as they can both be increased by a fair amount.
I have also disabled hibernation in Windows 7, as the issue occurred at some point while the machine was in hibernation state. It went into hibernation with 4GB and woke up with only 2GB. I realize this does not mean hibernation caused the problem, but could have played a factor.
I think I will slowly restore settings back to how had them before the problem occurred and I will be sure to test more thoroughly this time.
Thanks for help and advice
