    Epicne reacted to fybyfyby in Ryzen 5000 WHEA errors   
    So far I managed to find few workarounds, but didnt tried them all.
    These are:
    1)Setting EDC limit to 200A, Power Limit to 130W, Temp to 83C, Idle voltage to Typical, Disable Global C-States
    2)Turning off PBO and CBP - but you will loose lot of power
    3)Increasing DRAM Voltage by 0,05V - which is tip from MSI
    4)Setting max.CPU freq to 4400 MHz (for 5800X) at 1.35V
     
    These point seems to resolve WHEA errors for some people.
     
    Im currently trying point 1.
     
    I have to say, I go from stable configuration with R5 3600. I upgraded to R9 5900X. I have MSI B450 Carbon Pro AC and have Bios with Agesa 1.1.0.0 PatchD.
    I tried running on stock RAM freq (2133), turning off second CCD on CPU and many more things without success. My only hope are now (Im not counting putting 3600 back 🙂 ) these points and waiting for final BIOS.

    Epicne reacted to JacobFW in Optane on Older Hardware   
    READ THIS BEFORE LEAVING ANY SMARTASS COMMENTS
    1)  The reason I am making this post is I was unable to find any information AT ALL of people who had tried Intel Optane on older hardware.
    2)  I am NOT recommending people do something similar to my setup, or do this at all.
    I just wanted to give out some information on my experience
     
    So my current setup is a 4790k, 32gb of DDR3 2400mhz ram, 960gb Sandisk Extreme Pro with Win7.  I built this computer about 3 years ago, originally with a 4770k and 16gb 1866.  But my friend upgraded his computer last year so I bought his 4790k off of him for really cheap, then I got an amazing deal off of ebay for this ram, so here I am today.  This computer is serving me very well, and in most of the areas I use it for, it either matches, or slightly beats the Kaby Lake 7700k.  So frankly, I really see no reason to upgrade for a while.
     
    Then of course, Optane came out and we got to watch Intel give us the finger.  While Optane's sequential speeds do look rather handicapped compared to other NAND NVME drives, it's random 4K speeds are leaving me and alot of other people drooling:  5x higher than the second highest NAND NVME drive, and almost 10x higher than NAND SATA drives. Intel says it's mainly for caching with Mechanical Drives, but with that kind of difference, I think there's some potential for using it with SSDs as well...
     
    ....But it's only suppose to work on Windows 10 and with Kaby Lake Core series processors.  Windows 10 I haven't have had minimal issues with.  I have it on several computers and it works just fine.  But I don't see any reason to spend several hundred dollars on a new motherboard, cpu, & ram just so I could use optane, and I absolutely did not want to let Intel lead me by the arm to a mountain and offer me the kingdoms of the world, if only I bowed to them....
     
    ...But I still wanted to play with it.  Thankfully, I live near a Microcenter and several Fry's so if it didn't work I could just take it back.  So yesterday I ran down and grabbed the 32gb Optane Drive and a SIIG M.2 PCIe Adapter (my motherboard does have a m.2 slot but that would disable several sata ports I have things plugged into).

     
    So booting up, Windows immediately installed the driver the for PCIe adapter, but could not find a driver for the drive.  Doing some reading, turns out Win7 does not offer native support for NVME.  Microsoft does however offer a hotfix for it that you can find here:

    https://support.microsoft.com/en-us/help/2990941/update-to-add-native-driver-support-in-nvm-express-in-windows-7-and-windows-server-2008-r2
    So install that, restart, and.....
     

     
    BOOM BABY!!!!

    Intel Optane on a Haswell Processor and Windows 7.

    So running CrystalMark and....
     

     
    Sh*t.
    Figures right.  All the speeds are up to spec EXCEPT the 4k Random speeds.  There seems to be something bottlenecking the latency; comparing it to my Sandisk Extreme Pro you can see something's not right.  I'm hoping it's either the PCIe adapter or there's a problem with this optane drive itself.  If it's the NVME driver/Windows or an issue with the motherboard itself, this is really going to suck.
    Well until I can figure out what that problem is, there isn't really any point in continuing with the rest of my plans for this little project.   I'm not even going to bother trying out the Optane Program.  The way Intel uses the Optane as a cache is part software, but mostly built into the cpu itself.  
    My thought was to try and use PrimoCache, and use the Optane drive to cache my Sandisk SSD.  PrimoCache does say that it can be used to improve boot up times.  The downside is that rather than being built into the hardware, it has to load with the first part of the OS before it can start using the cache drive.  The upside is that in addition to an Optane cache, it also can be used to create a RamCache.  So there's some potential for some serious performance improvement.  Best of all is that it's significantly cheaper than a new motherboard, cpu, & ram.  
    So that's all for right now.  I ordered another PCIe adapter last night that should get here in the evening, and I have another computer with a Z97 board with Windows 10 and a built in NVME drive, so I'm going to try the optane on it and see what kind of results I get.
    So that should be all for now, but again, let me reiterate:
    This is an exploratory mission.  
    I'm not here to brag, but to let you all know that Optane does work mostly as it should on older hardware.  

    If you have any questions or helpful comments please let me know.
    Jacob
