MSI 990XA-GD55 and Corsair Vengeance 1866mhz problem!

I got MSI 990XA-GD55 and 2x4GB Corsair Vengeance 1866mhz but i tried everything to get it run at 1866mhz and i couldn't. It doesn't even run at 1600mhz. Only at 1333 or around 1500mhz. I set the timings manually but i doesn't work. Am i doing something wrong? Anyone can help me to figure out?

By saying memory controller, it's about CPU or mainboard?
AMD cpu's from the phenom series support 1066/1266/1333/1600(usually only supports that with an overclock and 2 dimms installed) MHZ on the memory controler! only way you can get more frequancy is by overclocking the memory controler on the cpu to allow the increased frequancy on the dimms (most ram that says its 1866mhz is ment that its been tested overclocked at that speed but the chips will more then likely be 1600MHZ)!

  • MSI 990XA-GD55 Mobo: Boots fine, no POST/chance to enter setup

    So I have built my own setup here, been running it since May of this last year. I never thought about it until recently, but my computer has never done a POST, or shown me the screen that allows me to get to BIOS or Boot screens. The computer has been running fine, until recently (About a month ago or so) I will be playing any kind of game, and the computer just COMPLETELY crashes. No closing of the game and shutting itself down, no blue screens, just one second the comp is running, and the next it is shut down. So I did a stress test of CPU and GPU to see if they were just overheating or were on their way out the door... But both passed stress tests just fine. I then wanted to check my memory/BIOS, and this is where the no POST and setup screen "clicked" for me... I have been searching everywhere for info on this topic, and the best I can come up with is that there is a problem with my G Skill memory not being recognized? I have DDR3 1600 going, as it shows I can use up to at least 1866 without OC on this mobo. So I went to check what my BIOS said, went to owners manual to see how to get to it (As I never saw the screen where it asks you to press "Delete" or F11), yet in the manual, it says to look for exactly that. So I guess my MAIN question is... How do I get my computer to show me that screen on startup? I have read to reset the jumper to the 2-3 position for 15 seconds on the JBAT, and if that does not work, to pop out the CMOS battery... But wanted to get other opinions before I attempted such things. And in doing this, and possibly getting to the BIOS screen, will that even help me with my original problem of my computer all of a sudden crashing in prolonged "stress" situations? Ie, playing Lord of The Rings Online, I generally have to play for a few hours before it crashes as such. I tried to play Assassins Creed 3 today, and it crashed in the first 10 minutes. This led to my investigation into the GPU (As it only really occurs when playing video games). I was thinking the system was just overheating and auto turning itself off to protect, but after doing the stress tests, GPU stayed pretty stable at 80-85c over an hour, and CPU stayed below 76c on an hour stress test. I even did an hour PSU test, no crash... The only thing I can think would be memory.
    I apologize for the multitude of questions and possibly incoherent order in which I wrote, but just trying to get as much pertinent info/process I went through as possible. Thanks in advance for any replies, and will be happy to give any extra info if needed!

    EDIT: After looking through all the left over cases from items I purchased when building this comp, I realize I actually purchased 1866 DDR3, not 1600. But in looking at system properties here, it registers as 1600... But as I said before, I cannot access BIOS to adjust these values. Or maybe that is my problem in first place?

    I was wondering about a good voltage for this setup, I think these two are running at 1.6V to start with... So going lower voltage would be ideal then, hmm? Less heat, less power consumption, and you do not have to worry about a decrease in performance? Especially if the latencies are lower, correct?
    And I hate to say this, but I have had one of my first "noob" moments ever with this problem... It has been a few months since I took some compressed air to the mobo.. So went and bought some, blasted the heck outta the CPU/GPU/PSU, and the North/South bridges... Ran the same CPU stress test for twice as long, and it hovered at 41c, 42c was my max... *facepalm*. Before, it was even overclocking the CPU to 3.8GHz or so to work with the "data" it was running.. After compressed air, never really went above the 3.6 stock speed. I have never felt like such a goober!
    As for the BIOS, turns out the F lock solved the problem, as the delete key is somehow considered a function key for this keyboard I guess. Was able to get into the BIOS, do some tweaking and all. Still nice to know that these newer systems dont beep anymore, and where to start pressing the delete key, instead of mashing it from boot!
    Yet again, thanks for the tips, and this bit on memory/RAM is interesting, thank you for that input as well! I do not plan on upgrading the CPU any time soon, unless it is in a weakened state thanks to my neglect.. But I am still fuzzy on RAM details, so the mention of Latency/Voltage helped me in my upgrade search, thank you! If I am understanding it correctly, the 1866 will be future proofed, as well as having the ability for lower latencies compared to 1600? Does my system not go to 1866 because of the CPU or the mobo? As I thought the mobo supported up to 2133 OC.. So most likely the CPU, correct? I am looking at some Mushkin memory, if I get some 1866, I can lower its frequency to 1600, but decrease its latency in the process? ie getting some CL9, and lowering it to 1600 and CL8? How would I go about this, if you do not mind my asking? (If I understand correctly).
    Thanks again!
    EDIT: I brought up the msi control center, and see that my RAM is actually running at ~1.5V. How can I see the latencies it is running at? It is rated at CL9 at 1866..

  • MSI 990XA-GD55 + Vertex 3 Max IOPS SSD

    I used to run my V3 MIOPS as the boot drive on an AMD 890GX+SB850 chipset motherboard with an AMD Phenom II x4 840 cpu. Everything was perfect and the computer was snappy. Programs opened instantly and multitasking was effortless.
    Then I upgraded the motherboard to a MSI 990XA-GD55 (AMD 990X+SB950 chipset) and replaced the 840 with the 1090T. I secure erased the V3, cleared CMOS and did a fresh install of Windows 7. Immediately I experienced freezings. I was advised by a member on the OCZ Forums to change the AMD AHCI drivers to the generic MSAHCI drivers. This stopped the freezings and improved the 4K Read/Write performance tremendously.
    I don't get freezings anymore and the computer is 100% stable. But whenever I try to open a new program or multitask I experience a lot of hesitations, not freezings. It's like the system is waiting for a routine to complete before passing back control to the user. This makes my computer less than snappy. The hestitation is usually a very short instance when I open a program but could be a few seconds if I already have a lot of apps opened and I'm opening a new app.
    AMD does not have specific SB/AHCI drivers for the 9xx series chipsets. I'm wondering what I can do to return the computer back to the snappy performance I used to enjoy with my old system. I suspect that AMD's new 990X chipset is the culprit. Does MSI have any new (beta) BIOS/drivers I could try to bring back my computer to its past snappy performance?
    Thank you in advance for any response.

    Just want to give an update here.
    I've fixed the problem by combining the suggestions given by MSI Technical Support and the ppl who responded to this thread. Thank you.
    MSI Technical had given me a new BIOS to try but it didn't fix the problem straight away. I suspected it was because of the AMD drivers I had previously downloaded from AMD's site and already had installed. It seemed that the original AMD drivers did not work well with the 990XA-GD55 plus the Vertex 3.
    This is how I made it work. I left the motherboard BIOS at the newest version, ie. V22.2B6. I secure erased the V3 and unplugged it from the motherboard. Then I thoroughly cleared CMOS and took out the battery for 15 minutes.
    Put back everything together and loaded the optimal defaults in BIOS. Set SATA to AHCI and rebooted with the Win 7 installation disk. Performed a fresh install of Win 7 (as recommended by Bas) but only used the drivers in the MSI Install Disk that came with the motherboard.
    Now everything is faster, especially the 4K performance of the SSD. I don't know about the "hesitations" as I haven't used the computer long enough yet (just finished re-installing all my apps). But the computer is now just as snappy as before. And yes, I'm now on AMD_SATA and not on MSAHCI.
    My conclusion is that the drivers (Catalyst/SB/AHCI) available from the AMD site is not good for the motherboard but those provided by MSI are perfect (in my case at least).
    Thanks again to everyone for their help.

  • MSI x58 ProE and Corsair 12GB (3x4GB) RAM Issues

    Greetings!
    New poster here with a question that I cannot seem to find an answer to anywhere. I've looked over the forums but have had no luck figuring it out. My goal is to identify the culprit and replace the appropriate parts.
    I built this computer in 2009 with the intention of doing OpenCL/CUDA computing and handle all my multimedia. At the time, 6GB DDR3 RAM (3x2GB) was about all I could afford. The machine works great, but lately, attempting to do some video and image processing has been hitting limits on my available RAM. I also want to run a linux VM or two. I thought I would order the Corsair 3x4GB DDR3 kit from NewEgg and not have any problems upgrading. I didn't have any plans of running the 6 and 12 GB sets simultaneously because I thought there would be some sort of memory density/timing issues.
    New RAM desired: Corsair Dominator with DHX Pro Connector and Airflow II Fan - DDR3 Memory Kit (CMP12GX3M3A1600C9)
    Old RAM in system: Corsair Dominator with DHX Pro Connector - 6GB Triple Channel (CMP6GX3M3A1600C8)
    Request 1: Can I mix the 6 and 12 GB sets (for a total of 18GB) if I keep the density the same across each set of slots? There are 3 black (primary) and 3 blue (secondary). I was thinking of putting the 12GB in black, and 6GB in Blue.
    I placed the order, received it, and went to install it yesterday. Took the existing 6GB out and dropped the 12GB in, saw that BIOS recogized it with the right timings, and proceeded to boot Windows up. Blue-screen at the very first Windows logo. I thought "well that stinks, let's check to see if the RAM is defective through MemTest." Downloaded an ISO of 4.2, fired it up, and it hung right away. Hung in the "Address Test, Own Address" test. Big fat A note: BIOS and MemTest both recognized the full capacity of the sticks.
    My next thought was "Well, one of them might be bad, let's try to find out which one." I individually put each one in the first slot on the board, ran MemTest, and showed 0 problems on any tests with each of them.
    Summary thus far: Individually, each 4GB stick works perfectly. In combination, they fail. The full 3x2GB set works perfectly.
    My next theory was that my board might be bad (even though the 3x2GB set in the same slots has no issues). Knowing that the first slot was good with every bit of memory I put in there, I left a 4GB stick in slot 1, and dropped a 4GB stick in slot 2. MemTest hung again. Thinking it might have been that one stick, I put the other one in there, and it hung also. So, slot 2 looks suspect. Move the sticks to 1&3, and they look fine, but that still leaves me missing 4GB of RAM.
    I've followed advice and re-seated the CPU, looked for bent pins (none found), and tried manually setting the timings to the 9-9-9-24 that is printed on the sticks. No luck with any of that.
    Request 2: So, my question to you is what am I missing? I feel like the board is the problem, due to the slot 2 problem with the 4GB sticks. However, my 2GB sticks don't have any problems at all in the same slots. Could the 4GB sticks require a little more power that my board might not be pushing out (the board is labeled at 1.5V, the sticks are labeled 9-9-9-24, 1.65V)? Would a bent pin be causing this that my eyes just cannot see? I read somewhere that a guy had a pin that was 0.25mm off that was causing his problems.
    Or should I be looking at the memory? The 3x2GB set works fine, but the 3x4GB does not.
    I'm not sure what my next step should be other than replace the RAM first, motherboard second. The RAM I just got, so I could RMA it if I knew exactly what the problem was. The motherboard is approaching 3 years old and presumably is out of warranty. I wouldn't mind replacing it, but I don't want to spend money right now if I don't have to.
    I don't have a second machine to test on, although I'm trying to locate one (most of my friends don't build custom PCs). I have also tried putting the 6GB in the black slots and 12GB in the blue, but the machine doesn't work with that configuration either.
    Request 3: Could someone explain how I could aim for 1066MHz on my RAM? I read that on the X58 Pro-E that this resolves most problems with random bluescreens. When I try to do this, I get lost in the numbers/options within the BIOS.
    Anything else I might be missing? I'm out of ideas
    Thank you all so much for the help!

    Hi and welcome,
    You have 2 "bottlenecks": the processor and the mainboard.

    As you can see, above 1066MHz you need to overclock both the processor and the mainboard.
    I think for your config the best shot is 3 x 4GB DDR3-1333 (9-9-9-24 at 1.55-1.60V)

  • Compatibility between MSI i7 boards and Corsair DDR3 RAM kits?

    Similar issues from other posters: Thread 1, Thread 2
    Are there any known compatibility issues between MSI's Intel i7 boards and Corsair's 1600 DDR3 triple-channel kits?
    My brother's machine (which has been discussed here before last time I tried to fix it) is still having trouble, and also uses the same type of RAM as the two threads above. The symptoms are:
    1) Occasional lockups, followed by a reboot
    2) Inability to POST: the machine will try numerous times, rebooting each time (as in threads 1 and 2), followed (eventually) by the POST saying "the previous overclocking has failed and the BIOS is reset to default settings" - as in thread 1. The machine will then (normally) boot. Reducing the RAM speed increases the chance of a successful boot, but the settings don't stick (presumably they are wiped when the BIOS is reset to the default settings). Cold boots (after the machine has been switched off overnight) tend to be the most likely to fail.
    Any ideas what could be causing this, if not an incompatibility with the RAM (in 3-channel mode)? Dropping down to one stick stabilises the system, but at the expense of dropping to a mere 2GB of RAM.

    Quote from: HU16E on 06-September-09, 15:10:01
    Out of seven MSI X58 boards, none had a problem with Corsair sticks. With the 1600's running at 1066, they should only require default (1.50v) auto voltage. They should also work using settings of 1N 9 9 9 24 without issue. As the CPU IMC only natively supports 800/1066, your particular CPU may have a limitation of working any higher. But, something is not right within the system if it will not run the RAM at 1066. To rule out a bad stick, test with just one in the black A0 slot, & swap it out & test the other two individually. As far as DRAM voltage, if all the sticks check out ok, try raising it to 1.55V. Keep the forum updated on your progress. 
    Added: Make sure 'Spread Spectrum' is disabled in bios Cell Menu, as well as 'Extreme Memory Profile' if your bios has it listed.
    Are they 2GB sticks? (All the threads in question use the 2GB sticks - one 3×, and one 6×)
    Back around the time I tried the BIOS flash as the solution, I Memtest86'd each of the sticks individually in the MSI-recommended slot for a single-stick configuration, and each tested perfectly. Part of the advice given at the time was to disable XMP and Spread Spectrum; they already were.
    Whilst I can't be certain that the RAM is the problem, at least three threads on this board now are using 2GB Corsair 1600 sticks and having strikingly similar symptoms...
    I'll try investigating the voltages later today. Thanks!

  • Need help for my P67 GD55 with Corsair Vengeance

    Hello, all
    I just bought MSI gd 55 with  corsair vengenance
    http://www.newegg.com/Product/Product.aspx?Item=N82E16820233142&cm_re=vengenance-_-20-233-142-_-Product
    The default setting by MB is 1333Mhz when I first turn it on. So I manually set them all to the corsair speed. (including SPD timing)
    It won't boot with 1.53v voltage.
    K, so I set it to 1600MHz, it rran smoothly and the system was stable even in high stress gaming.
    However, when I did a fresh start up.....it won't boot again and boost me back to 1333 Mhz..
    I have been tried this like 3 times now,  I already sent a ticket to Corsair, will see what happen
    Because newegg is accepting return due to 67 chpiest issue, if it won't work due to the incomplaity between MB and corsair.
    Guess i should pick up Asus MB again which my old one was using (X48)
    I'm not sure what's the problem from, the MB or memory
    Anyone has an idea? I hate to fill up a MSI ticket due to it's long enough to write...It's headach
     

    -------------__________________--------------------------
    Was the intel's chipest issue all about SATA 2 internal voltage ?
    I think it has nothing to do with the memory's speed.
    At least, corsair works fine with my old asus X48...........Probably asus is the last brand I can choose. Gigabyte is also garbage, my old x38 only last 2 months, then it was dead....repaired.........4 more weeks, it was dead again.
    Finally, newegg replaced a asus x48 from gigabyte x38.
    Then, the asus x48 never stop working again.   
    "Here's the thing we can confirm, the problem is to be found solely in the SATA 300 controller, the SATA 600 controllers are unaffected as well as any other added controllers on your motherboard.
    On the up-to four SATA2 (SATA 300) ports in a timeframe measured over years, your performance failure rate 5% to 15% based on standard usage. The controller simply will produce more errors and as that result the controller performance thus will go down as it tries to correct it. Worst case scenario is that the overhead would get so big that your HDD/SSD would not be recognized in Windows any longer. These predictions are all based on statistical numbers though

  • MSI KT6 Delta and Auto update page problem

    Hi, I have been lookin for the right forum to post this on for awhile heh but I have an MSI KT6 Delta FIS2R which has an auto update feature that uses an icon on ur desktop called MSI Live Update.

  • MSI 990XA-GD55 Low FSB and CPU voltage cap

    I just purchased a brand spanking new 8120 and I'm loving it right now. I've been steadily OC'ing it and have gotten it to 4.5 Only with the multiplier. I wanted to do it with my FSB but it will only go up to 225, after that it stops posting. I keep everything close to stock as i pump it up but if i go up to 226 and keep everything low it doesnt post. I thought that was fine and didnt worry about it till i saw people hitting 250+ with their MB. is it my board thats bad or am i doing something. I also cant up my voltage on my cpu past 1.4v which puts me at the 4.5 with a core temp of 50 running prime95.

    >>Posting Guide<<
     Do you know you can't just up the Reference clockrate ("FSB") without modifying the HT-Link to not massively overclock the linked components.

  • MOVED: MSI 770-G45 and 4x2GB DDR3 1600 problem

    This topic has been moved to AMD64 ATI/SiS/VIA boards.
    https://forum-en.msi.com/index.php?topic=153078.0

    You are in the wrong part of the forum with that motherboard. Please make a new post, listing all your hardware, here:
    https://forum-en.msi.com/index.php?board=24.0
    Since the problem is memory detection, you need to say model exactly.
    Now I can only advice you to set memory speed down, to 1333 for starters. Also check if the memory wants a special voltage. For example, Corsair usually wants 1,65 volts.

    I have a problem with my board (I think) and memory.

  • MSI Neo4-F and Corsair Value Select DDR400 512x2 Cas 2.5 unstable to the max

    Hi, how can I fix this ?

    I know this caused the problems cause I switched to KINGSTON Value RAM Cas3 512x2 DDR400 and its 100% stable now.
    Please help me I need to return the Kingston.

    Hi there,
    The colors of the dimms are to diferenciate the channels (because of the dual channel thing) one color is channel A the other channel B.
    So when you put 1 stick in one color and the other in another then you have a dual channel memory system, if you put the 2 sticks in the same color slots then you have a single channel memory system and less performance (obviously ).
    As for the voltage, there is a very very very ....... long term damage, if the memory was not intended to work at that voltage, but do not worry about that.
    Be well....
