Core Voltage for 5820k on X99s Gaming 7

Hi there, I am new to the forums and MSI..
This is my first msi board, so far so good, I have the x99s Gaming 7 with i7-5820k, 16 GB 4x4 of Corsair Vengeance 2800 with 1000w EVGA P2 and NH-D15 cooler, 250GB Samsung 840 SSD and my video card is crap but I plan on getting gtx 970/980...
I was able to get 4.5 GHZ all I had to do was increase multiplier to 45 and core voltage to 1.35v
Here is my question...
I plan to run 24/7 and happy with 4.0 GHZ OC..
I left everything on auto and change my cpu vcore voltage to 1.14v..
I have my ram at 2666Mhz..
My idle temps are 38C-41c..with load at max of 63C after running for a few hours with aida64
I am curious to see what others have used for there vcore voltage for 4.0 Ghz OC
Any way to use my ram at 2800MHZ without using XMP?
Is there a way to have a variable vcore voltage, so that will use little power but ramp up when under load?
This is my first attempt at overclocking
PS what do you guys have your CPU fans set to I am using variable speeds starting with 50%@ 40C, can you give some recommendations?
Thanks

First, Welcome to overclocking.

What is the room/ambiant temperature
This CPU max Tcase is 66.8c, you may want to keep it below this except maybe for short time stress tests.

For my CPU(different than yours) I have increased vcore 0.01v above stock.
I suggest you first see what cores VID is at default, set BIOS vcore until you get the same VID and take it from there. It may be stable with less or require a little more, every CPU is different.
Besode voltages CPU frequency ay be throttled if CPU power consumption reached it's limit. There are options in CPU Features to change power/current limits.
Everyone make their own definition of stable, so it's up to you what tests you want it to pass, I don't know AIDA's stress, but I believe Prime95 (v28.5 or above) would be much more stressful, and should not be a problem with your cooler/voltage.

Sure, set DDR at the level you wish, and set timings  and voltage manually according to specs.
The question is why not use XMP, uless you want it over 2800, and even then BIOS will scale some settings you wouldn't know to change manually according to its logic.

By default, that's how it works, vcore increases according to load, if not there are options in BIOS to change it. Set CPU Core Voltage Mode to adaptive if it is set to override by default.
I like HWiNFO for monitoring, it's free.

  • Control Voltage for Msi GTX 760 Gaming

     We can see MSI GTX 760 Gaming has 8 pin + 6 pin conector so good for up to 300W but MSI Afterburner only add 12mV, it's too small with board power and it;s cooler, more voltage can be possible in future

    No, nvidia restricts available overvoltage. MSI won't add more overvoltage possibilities.

  • X99S GAMING 9 AC Not booting - Debug 94 code - Issue with GTX 980 SLI in WoW

    Hello, I bought the X99S GAMING 9 AC motherboard but have ran into some issues.
    The computer won't boot when I put my second MSI GTX 980 Gaming 4 GB card in the last PCEI 3.0 port (PCIE port 5) and I get the debug LED message 94 on the motherboard. I have a SLI setup.
    The first card I have in the second PCIE 3.0 port due to the Noctua U14S CPU fan takes up space for the first slot. So I have been running my grafic cards in PCIE slot 2 and 4 with some issues.
    First the card in slot 2 gets really warm over 86 celsius. And second: SLI runs really poorly in World of Warcraft. I get a lot higher performance with just one card activated. I am not sure if it's cause I am not running my cards in the recommended PCIE 3.0 ports or because WoW has some issues with SLI, but I heard other people have no issues at all with WoW in SLI.
    I got the same issue with 3Dmark firestrike, the cards perform really poor in SLI. I get higher score with SLI turned off..
    Though SLI seems to run pretty well in 3dmark 11 and Diablo 3 Reaper of Souls.
    But the main issue right now, is that the computer won't boot with the grafic cards in PCIE port 2 and 5. The solution to run them next to each other is not good, cause it gets really hot and I get bad performance in WoW and Firestrike.
    Picture of my setup before I switched places with the grafic cards as you can see, it is really tight:
    Any upcoming bios updates (got v1.3) that will solve this issue on the horization? Hopefully this get sorted out really soon..
    My whole computer setup:
    Intel i7 5820K | MSI X99S Gaming 9 AC (bios 1.3) | SLI MSI GTX 980 Gaming 4GB | Samsung 850 Pro 512 GB | WD Red 4TB | G.Skill Ripjaws DDR4 3000MHz 4x4GB | EVGA SuperNOVA P2 1000W | Noctua NH-U14S PnP | Fractal Design Define XL R2 | 5 Noctua NF-A14 PWM 140mm fans | Windows 7 Pro 64 bit

    You must use the recommended PCIE slots as the manual says for your CPU type, PCIE #1 and PCIE #4 if I remember, just open the manual :P for optimal 2Way SLI, also your 5820k will limit to 28 pcie lanes only if you plan to add more vgas...the other problem is your giant CPU air cooler blocking PCIE#1, do a favor to yourself, buy a watercooler for your 5820k and your problems are gone, add some overclock in your system, low noise and better temps.
    Here I use 3x980 in SLI with X99S Gaming 9 AC, going soon to WC the VGAs with EK blocks.....3way is far more temperature critical than 2way spaced one.
    Cheers

  • Problem with X99S GAMING 9 AC - PCIE-PORT reporting V1.1 same with SLI

    Yeah as the topic is saying, I got issue with my PCIE 3.0 ports, they are saying my grafic cards are running at x8 1.1
    I should first mention that I had these issues for a while, and I also updated all drivers to the latest versions, but still same issues. I got the 1,4 bios version for the motherboard and the nvidia V344.65 that was released today.
    I tried to change it in bios from auto to gen 3 on the PCIE-ports, but still same results.
    I made a post earlier about that SLI running slow in WoW and 3Dmark Firestrike. Maybe this is the source to the issue due to the ports running at 1.1 and not 3.0?
    Also, in both WoW and 3Dmark Firestrike, I get much higher FPS and results with just one grafic card activated, when I go into SLI the results drop like a rock..
    The weird thing about SLI though, that it seems to work okay in games like Diablo 3 ROS and 3Dmark11.
    I have my grafic cards in the recommended PCIE-ports, 1 and 4.
    Here is a screenshot how it looks like in GPU-z:
    Is this a known issue and is there any upcoming fix to this? Feels really bad I can't use my grafic cards to their fullest potential..
    My whole computer setup:
    Intel i7 5820K | MSI X99S Gaming 9 AC (bios 1.3) | SLI MSI GTX 980 Gaming 4GB | Samsung 850 Pro 512 GB | WD Red 4TB | G.Skill Ripjaws DDR4 3000MHz 4x4GB | EVGA SuperNOVA P2 1000W | Noctua NH-U14S PnP | Fractal Design Define XL R2 | 5 Noctua NF-A14 PWM 140mm fans | Windows 7 Pro 64 bit

    its probably because the render test doesn't handle or don't support SLI well and second card become back to idle
    run something else apps., bench or games who support SLI well then check their modes
    Enable sli load balancing if needs from nvidia control panel to check SLI utilization
    Seems to work the correct way when I start a game, but still got issues with WoW and 3Dmark firestrike. My results with SLI is far worse then with just one single card activated. Anyone know why?
    I get more FPS from WoW with one card then two, and I get much higher score in 3Dmark firestrike with just one card..

  • Core 2 Duo e7300 core voltage

    As reported by CPUz, my core voltage is 1.184V.
    However, I have seen in some reviews that e7300 core voltage is 1.168V.
    Specs: MSI P7NGM-Digital motherboard
    Corsair XMS2 2GB 800MHz
    So whts the default core voltage for e7300 ?

    There can be slight differences between different CPU exemplars, that is why Intel cannot tell you the precise default VCore for its different processors and if Intel cannot tell you that, nobody else can. 
    Therefore:

    A difference of 0.012V is a rather insignificant difference. Don't worry about it.

  • Safe Core Voltage

    I forgot to ask this question along while asking about a safe memory voltage, but how far can I safely increase the core voltage for my CPU(P4 2.60C 800FSB) which at now is  running @ the default 1.54v. I'm interested in oc'ing a bit more without the danger of it frying. Thank you!  ?(

    Hi,
    IMHO is the absolut maximum 1.75, better 1.70VCore.
    Look @ http://www.overclockers.com Forum and search for SNDS (Sudden NorthwoodDeathSyndrom).
    My Northwood 2.4B runs since 5 Month at a maximum of 1.70V and i have no problems, but i am also watercooled and i have the Graphiccard in the Watercooled System.
    The problem with the MSI Boards could be the Temp readings, i seems to be to high. Withe the Epox EP4BEA and the Proc @2.700MhZ i had a maximum of ~45°C and now with the 865PE from MSI the CoreCenter shows 51°C and under absolut fulload over Hours a max of 58°C.

  • Msi gaming 7 cpu core voltage diffrences

    Hello guys I'm trying to OC my 4770k.For the beginning I made cpu ratio 4.2 with 1.255 core voltage.The thing is my aida64 cpuID and cpu-z shows 1.272 which is quite high from what I have set.Not even lower(vdrops etc.) so which one I should take care.System seems to run stable.Tested it with aida system stablity check for 20-25 min.Temp were 82(my room is hot)I use coolermaster hyper 212 evo.
    Also is there also tweaks should I consider for OC'ing?

    CPU V. can reach up to 1.400v's before it becomes a genuine concern. You will most likely exceed the recommended maximum CPU temperature way before reaching that voltage. It makes no sense to fix and run full throttle all the time at idle and low use for an everyday type machine. Leave the RAM at default (XMP disabled) until the CPU OC is confirmed stable, then work on the RAM speed settings.
    Need a screen shot of the sub section 'CPU Features'.
    Actually, leave everything on auto/default/stock, use M-Flash, BIOS + ME option and update to the V1.4 BIOS. After the flash re-install the newest ME driver from an MSI Website of your choice, Global, Europe, or USA. Will repeat, I bought a Radio Shack el-cheapo DMM for under 20 bucks and it works great and extremely accurate. DMM is the only way to verify if the readings you see are correct.
    Nice thing about Z97 (and Z87) is you can set the CPU Ratio out of auto and not lose the power saving features. EIST and C1E can be enabled to throttle down for idle and low use. Another OC method is the Turbo Method with Turbo and Enhanced Turbo enabled leaving the CPU Ratio on auto and simply setting the 4 Core Ratios in CPU Features.

    2. Tried the video card in another PC, working fine, also tried it in each pci express slot (four of them) on the MSI X99S GAMING 7 board.
    3. Tried resetting the bios and have also tried booting with just one memory stick in Dimm slot 1
    4. Tried powering up the board out of the case with just the power supply, video and memory connected.
    and it still get the samme problem as before and still stand on code 04 and still not boot up.

    You can simply press the button next to the PS/2 and USB 2.0 ports with the power cord unplugged. Or best way to clear cmos is by taking out the battery (around PCI-E_1 and 3) for more than 5 sec and then put it back, also with the power cord unplugged.

  • MSI X99S Gaming 7 Won't Boot

    Hi -
    I just recently purchased an X99S motherboard.  I put it all together, and all was fine for about 24 hours.  I updated the BIOS and then started running a defrag and left the machine on while I went to work.  When I got home, the machine was off. It's not responding to the power button the board or on my case.  If I turn the power off on my PSU and turn it back on and hit the power switch, I get a split second flash of lights and then nothing.  I initially thought that it was my power supply so I bought a new one.  I got that installed and same thing.  One thing to note is that the MSI LED up by the 24 pin connector is on red.  I've already tried the secondary BIOS and I have removed all of the memory except the DIMM in Slot 7. I haven't yet tried to remove the board from the case yet and tried it on a non conductive surface.  I just wanted to get some thoughts on that debug LED that is currently on. I believe the motherboard has just died, but wanted to run it by someone first.
    Here are my specs:
    Board: MSI X99S Gaming 7
    Bios: Version 14.7
    VGA:   MSI GTX980 Gaming
    PSU:   EVGA 1000 Watt G2
    CPU:  Intel Core i7-5930K 3.5GHz

    HDD: PNY 256GB SSD
    COOLER: Corsair CWCH60 Water Cooler
    OC: None
    OS: Windows 8.1 64bit

    Take it out of the case, place on non conductive surface (wooden table, motherboard box) and run it then. Also try with single RAM stick in every RAM slot.
    Try clearing CMOS >>Clear CMOS Guide<<
    Also make sure all power connectors are properly fitted in.
    What way did you update the BIOS? Also was it successful?

  • Core Voltage wont OC on N680GTX Lightning!

    Hi everybody! 
    I recently bought a brand new gaming PC, after years and years of being a notebook gamer.. So, i finally decided to play around with the overclock settings for my GPU
    I have the Z77 MPOWER Motherboard, and as for my GPU, I have the N680GTX Lightning. My system is running windows 7 x64. I use MSI Afterburner 2.3.1 for applying the overclocking, and Furmark for testing (instead of Kombuster)
    I'm all new to overclocking, so i started reading about it, and came across this review of the GPU:
    -Link here, but this damn forum says: "Sorry, you are not allowed to post external links." darn..
    And they clearly figured out some nice overclocking settings for the GPU. Allthough, I didn't know if I should just change the settings to those levels right away, so i kept looking and found another post:
    -Link here, but this damn forum says: "Sorry, you are not allowed to post external links." darn..
    So i started to slowly apply the overclocking to my Core Clock, and everything was well. I was able to get it to +70/80 before the drivers started to crash. Then i went ahead to start applying the Core Voltage overclocking (slowly increasing the Voltage a little bit at a time), i realized, that when i increase the Core Voltage (to ex. +12 or +25), nothing happens to "GPU voltage, V" in the monitor screen in Afterburner. It just stays at 1175'ish. When i increase the value and press "Apply", it drops to 1100 for like 1/4 of a second, and then goes up to 1175 again. And no matter how much i increase the Core Voltage, it just wont go higher than 1175. When i apply the overclock, GPU-Z also says that the "GPU Clock boost" still is at 1176 (Just like the Default Clock, so nothing has changed). Now, I did increase the Power Limit from 100 to 133%, and i checked "Unlock voltage control", "Unlock voltage monitoring" and "Force constant voltage"(allthough i don't really know what "Force constant voltage" does, but i have the same problem with applying the voltage overclock whether i have it checked or not). I also set the UAC settings to "disabled"(Never notify), as i did read somewhere that that could be the problem. Didn't help me though..
    Is anybody else experiencing the same problem? Or does anyone have any idea of what i do wrong? Hope somebody can help me!

    Hi, the easy answer is you need to use older 2.2.3 AB version as Nvidia forced MSI AB to lock out voltage tweaks .
    Now onto voltage monitoring, even if you use older AB the voltage will not show correctly in GPU-Z or AB, it will show 1.175 approx , but that is not including the offset added voltage because the PE/lightening models add voltage on top of reference regulator .
    SO just add offset to GPU-Z and should be close to right voltage .

  • MSI x99 Gaming 7 Crashing during Windows UEFI Boot

    Hello everyone,
    I'm dealing with a strange problem here and i cannot seem to find any solution. Yesterday i updated my m/b bios from H.8 to H.9 and everything worked fine but 30 minutes later during some regular windows and drivers updates i restarted the machine only to find it crashing during windows loading logo when booting. I initially thought to be something about the new bios update (or windows/drivers updates) so i switched to the back-up bios ,updated it to H.8 (which i was using before) and did a quick format but the problem still occurs.
    I pinpointed the problem to be something in the bios (bios update resets settings to defaults both when i updated to H.9 for the main bios & H.8 for the backup bios) and the UEFI settings for windows 8.1 since  it doesn't occur when i disable the "Windows 8/8.1 Feature". What exactly does this feature do? The only difference i saw was the loading logo , now i see MSI red/black picture with the small circle-dots loading instead of a Black screen with white MSI logo if i enable the feature.
    My system is new (three months old) and i never had any crash or lock-up anywhere (nor it is overclocked). All settings in the bios are default except the "Boot Mode Select" is UEFI and the "MSI Fast boot" is enabled. Windows 8.1 64Bit are installed in UEFI mode.

    -Gigabyte 970 G1 Gaming SLI
    -Samsung 850 Pro 256GB
    -EVGA SuperNOVA 1000 G2

    Ok ,seem to have some updates:
    First of all i was wrong about the SATA ports i was using (my second GPU blocks the view of the ports).
    - SSD was connected to SATA3 while the other two HDD's to SATA10 & 9
    I first disabled Samsung RAPID mode (you never know). Then i changed the SSD from SATA3 to SATA1 port and didn't connected the other 2HDD's at all. Enabled the "Windwos 8/8.1 feature" & Secure Boot and quickly did 4-5 restarts from the bios and from Windows, even a cold boot. No crashes but i need to do more reboots to make sure it doesn't occur any more. Then i will connect the other two HDD's and check for crashes.
    Update#1 . Ok my other two HDD's are connected to SATA ports 3 & 4. After 3-4 restarts & 2 cold boots everything seems fine , no crashes at all. I don't know if maybe after 10 restarts it will occur but i'm confident enough that it should already be present now. So it seems that either Samsung Rapid Mode is responsible or the other SATA ports.
    Update#2 . So Samsung Rapid Mode seems to work fine, again no crashes at all. This is getting really weird. So that leaves me with the Sata ports ,now i don't know if i need to change again sata ports to recreate the problem or leave it as it is (working) but then again if it's indeed the SATA ports then maybe something is  faulty. Either way i'll check it.  :/
    Update#3 . I think i came to a conclusion. SATA ports 7-10 seem to have the problem.
    - I reconnected everything to the original ports i was using (SSD to SATA3 and 2xHDD's to SATA10 & 9) .The crash happens the second time i restart the PC.
    - Moved SSD to SATA1 , crash happens again at the second boot.
    - Moved the 2xHDD's to SATA 7&8 ,crash happens at first boot.
    - Moved the 2xHDD's to SATA 3&4 . NO Crash occurs.
    I have no idea what's going on, the manual states that SATA 7-10 support only IDE mode and AHCI (SATA 1-6 supports RAID 0,1,5,10). For the record i do not use RAID.
    So what is the problem? I didn't have any issues at all with the previous configuration. Did any of the SATA port's became faulty when using the "Windows 8/8.1 feature" after the bios update? Should i ask for a replacement?
    The last thing i could try is to unistall the Intel Rapid Storage. MSI's drivers site for this m/b has the 13.1.0.1058 version while Intel has 13.6.0.1002 but they do not work as it says platform is not supported. I have the MSI's version installed all this time.

  • Core voltage stability on 865PE Neo2 PFS

    I've just installed one of the new P-series NEO-2 MOBO's. Nice piece of work, although it seems there is still some work left to be done. Definite problems (although not serious) in Core center (althoug other posts indicate this may be indiginous to core center itself..)
    More serious though is a reading of the processor core voltage.
    I'm using a Celery 2.6, OC'd to 3.25G, FSB 125. Had to raise core voltage to 1.6V to get there, lower voltage led to crashes as low as FSB 104...
    Recently, I looked at a scan of the core voltage (provided by Speedfan):
    The problem lies in the fact that during disk access and/or high processor load, the core voltage drops as much as 90 mV, bringing it back to its default setting (spikes in graph, longer drop was writing DVD, CPU benchmark has similar result).
    If it does this at 1.5V, I can understand the crashes.
    I get the impression this board could do MUCH better with more stable voltage regulation.
    Anyone seeing similar behaviour in other Neo2-boards? Am I missing a setting?(core-cell may be intervening) It's hard to imagine the PSU can't hack it.. 12V level is rock solid.
    System: MSI 865PE Neo2 PFS, Celeron 2.6G @ 3.25G (125 FSB)
                 1x corsair 3200 512MB @ 333
                 POV 5600 VIVO
                 WD800BB 80GB
    PSU:      HEC 350 VD-PT (3.3V@28A, 5V@33A, 12V@15A)

    I'm not worrying. Just a bit surprised we all make a bug fuzz about overclocking, increasing core voltage by 25 mV at a time, and suddenly ignoring it all and "accepting" 70 mV drops if we need processing power...  
    If the voltage regulator would be more robust, it would be able to maintain the Vcore to (much?) higher power ratings.
    This board drops by roughly 70 mV, constituting 3 notches on the voltage setting tab.
    I went up to 1.6V, and what I actually get is 1.52.....  
    To have 1.6 available under all conditions, I'd need to set to 1.7 (yes, I've tried), which is over the top for "normal" overclocking (not to mention considerably higher temperatures).
    Anyway, I'd like to know what other boards are doing regarding Vcore stability. Anyone out there with additional data?
    Maybe a new target for modifications?  (if it's worth it...)
