  1. Corsair uses version numbers to identify the IC. see https://forum.corsair.com/v3/showthread.php?t=188134 Version 4.32 kits seem to have had some issues requiring some timing adjustments as you can find on the forums. I think the problem with RAM on AM4 is more general compatibility issues (not being as refined as Intel memory controllers and BIOS/UEFI) not necessary something specific with Corsair. Although I've read a lot of disparaging comments regarding OC'ing Corsair RAM too. Improvements have been made since the original launch of Ryzen but is seems getting XMP to work consistently across the platform can be hit or miss in which case just set your options manually, which is ok for someone who knows what their doing, but otherwise a problem and terrible experience for those who don't. From and end-user perspective I've never noticed a perceivable difference between 16-18-18-36 vs 20-20-20-44 or even between DDR4-3200 vs DDR4-3600 and for most people it probably won't matter. If your running at least DDR4-3200 with a Zen2 CPU that's good enough for anything with a good price to performance ratio. Personally I really like the aesthetics of the Vengeance RGB Pro and the hardware control for the RGB. I'd probably keep the B-die kit for both performance and compatibility (it's perhaps more rare to buy now too) but if you want to go for aesthetics looks like on newegg you can get Corsair RGB Pro for about $150 DDR4-3600. Didn't have a chance to use the light enhancement kit so not sure if it might make OC a bit more difficult. I found this website to find b-die...(I remember reading somewhere b-die is no longer in production) https://benzhaomin.github.io/bdiefinder/
  2. Hello duhfyy, I'm in no way a professional overclocker and it wouldn't feel right charging you for any service regarding that. My PM is disabled cause of information overload and one less thing to check for messages. There are a lot of posts I have participated in regarding or related to OC or getting RAM to work on AM4 platform you can get all the info you need to know. You can probably find a majority of them by searching "4.32". Perhaps start a new thread and give the info for the hardware you have and what you have tried and the community can try and help (including myself) Quick Tips: with your hardware... (I had the previous gen model of that board for a short time) - DDR4-3200 should be no problem on that board with a Zen2 cpu. Make sure you are using slots A2, B2. - If XMP profile is not working set XMP voltage, frequency, timings manually in that order. (also SOC 1.1v or a bit lower than that) - With 4.32 kits it seems to be a thing that tRC needs a bump somewhere between +2 to +8 over stock for some reason. - Memtest86 can be used to test memory quickly before getting into more extensive testing - DRAM Calculator for Ryzen may help you find the correct settings. (reading the Ryzen RAM Overclocking Guide can be quite helpful as well) - BIOS updates are important, make sure to have at least BIOS with AMD AGESA Combo-AM4 1.0.0.4 Patch B - Updated chipset drivers are a must and Windows 10 ver 1909 (minimum)
  3. Sounds like you got a bad stick. RMA/warranty seems to be the route to go. If you got the kit at a local store you might be able to get an exchange. Your motherboard supports ECC and your are doing stuff with multiple VM's with intensive memory tasks so you might consider that.
  4. Have you tried DRAM Calculator for Ryzen to help you find compatible settings?
  5. What's the version number of your kit? (should be printed on the back next to the model number) Although I may not be comparing apples to apples exactly I also have 3950x and pushing 64GB (with 4 dimms) beyond DDR4-3200 is difficult. Your mileage may very.
  6. I don't have my RGB ram installed at the moment but I found a picture of iCue ram settings on the internet here image of iCue Ram Settings that shows "Enable full software control". That is the option to uncheck to allow hardware control for the RAM. Then in iCue you continue to setup the RAM RGB with your preferences. Motherboard RGB are different solutions. There is probably software from your motherboard vendor you should download to control that. If your lucky you might have UEFI/BIOS control over motherboard RGB.
  7. If you switch to hardware control you can leave iCue closed if you don't want the additional CPU usage however you won't have as many effects. I do this for the fans and light strips. (The fan RGB might require commander pro if I remember correctly.)
  8. I believe the ram can run with software or hardware control. In iCue there should be an option that allows you to run with hardware control. Once set with hardware control the ram will retain your settings even if you put it into another computer. Google Translate: Ich glaube, der RAM kann mit Software- oder Hardwaresteuerung betrieben werden. In iCue sollte eine Option vorhanden sein, mit der Sie mit der Hardwaresteuerung arbeiten können. Nach dem Einrichten der Hardwaresteuerungen behält der RAM Ihre Einstellungen bei, auch wenn Sie ihn in einen anderen Computer einlegen.
  9. Nice! With GD disabled are you running CR at 1T or 2T? Since then I found it's behaving as samsung c-die and interestingly less voltage can be more stable for a higher overclock. Thanks to DirtyHarry in thread https://forum.corsair.com/v3/showthread.php?t=199955 for finding this helpful overclocking thread Samsung 8Gbit DDR4 C-Die K4A8G085WC - OC results... First try (a little unstable, pending adjustments) DRAM=1.33v, SOC=1.025 +(SOC-LLC=L1) >> 1.2v 20-22-22-48-68 1T GDM tRFC=630 (AUTO on the rest) DDR4-3733 106% https://www.userbenchmark.com/UserRun/33147352 DDR4-3800 107% https://www.userbenchmark.com/UserRun/33148103 My new B550 ITX motherboard has much better VRM and voltage control than my x470, but by default tends to juice the SOC a bit above 1.2v, and it took a bit to figure out where the right control was to bring it back down. Here is what I am currently playing with ... with ASRock B550 Phantom Gaming ITX CMW32GX4M2C3200C16 (ver 4.32, dual rank, 2 sticks, 32GB) DDR4-3800 20 - tCL 21 - tRCD 21 - tRP 48 - tRAS 68 - tRC 6 - tRRDS 9 - tRRDL 36 - tFAW 4 - tWTRS (last stable at 5) 12 - tWTRL (last stable at 14) 12 - tWR (last stable at 26) 4 - tRDRDSCL (last stable at 6) 4 - tWRWRSCL (last stable at 6) 590 - tRFC 18 - tCWL 6 - tRTP (last stable at 14) 8 - tRDWR (last stable at 12) 3 - tWRRD (last stable at 8) 2 - tWRWRSC (needed 2 to pass 128bit random number generation but this kills performance a bit) 6 - tWRWRSD 6 - tWRWRDD 2 - tRDRDSC (needed 2 to pass 128bit random number generation but this kills performance a bit) 4 - tRDRDSD 4 - tRDRDDD 2 - tCKE FCLK 1900 (keeping 1:1 ratio) DRAM = 1.33v SOC = 1.025v override mode CR = 1T Gear Down Mode = Enabled Power Down Mode = Disabled Spread Spectrum Enabled ProcODT = 36.9 ohms (I think with newer BIOS Zen2 CPU prefers lower ohms...I forgot how I landed at this value exactly) RTT_NOM = Disabled RTT_WR = RZQ/3(80) RTT_PARK = RZQ/1(240) CAD_BUS = All 24 ohms Even though I can FCLK my 3800x to 1900Mhz it's probably at the bleeding edge of stability. I'm not sure if what other voltage controls may help improve the sub timings.
  10. That might be samsung c-die. Try DRAM 1.33v, SOC 1.025v and see if that works better.
  11. Do you know the version of your memory kit (printed next to model number)?
  12. I'm on 3.30.97 as well and it seems pretty stable.
  13. What is the model and version number of your ram? Have you explored all the submenus? I have a difficult time believing they are not there. But then again I recently updated the BIOS on my x470 and they removed (or did not reimplement) a large section of BIOS that dealt with ram settings. The 2700x is Zen+ and it might have difficultly trying to push 4 sticks of ram at DDR4-3200. When DOCP is enabled can you downclock to DDR4-2933? (is zen+ spec btw)
  14. Interesting...I only read some pages of of the link so far but I got similar results and I can OC my kit to DDR4-3600 no problem on the B550 ITX board. Even to DDR4-3800 however at that speed memtest86 fails test 12 the 128bit random number test and I haven't figured out how to get around that which is too bad cause I know my 3800x can FCLK to 1900. *** update *** Thanks so much for that link. Reading a bit more in the thread starting around page 8 really paid off, so it turns out C-die can OC better at lower DRAM voltages. I retried DDR4-3733 at 1.33v and traded off 3000+ errors on memtest86 test 12 with 1 error on test 8, 1 error on test 11, and 1 error on test 12 - progress! I had just about given up trying to get anything over DDR4-3600 with my 4.32 kit but now I guess I've got a new hobby for the next few weeks. I'd thought I'd share my preliminary results. Corsair CMW32GX4M2C3200C16 (ver 4.32, dual rank, 2 sticks, 32GB) (stable, XMP + some tweaks) DRAM=1.35v, SOC=1.1v 16-18-18-36-75 1T GDM tRFC=500 DDR4-3200 93.6% https://www.userbenchmark.com/UserRun/33148460 (a little unstable, pending adjustments) DRAM=1.33v, SOC=1.025 +(SOC-LLC=L1) >> 1.2v 20-22-22-48-68 1T GDM tRFC=630 DDR4-3733 106% https://www.userbenchmark.com/UserRun/33147352 DDR4-3800 107% https://www.userbenchmark.com/UserRun/33148103
  15. Well that is what the QVL is for however if you do get some trouble you have a clear avenue to get support from the motherboard vendor because they claimed to support it. For example ASRock supports ECC and even though I used some ECC modules that weren't on the QVL they sent me a beta BIOS that fixed my issues. Of course it's possible that the fix was simply a downstream update from a new AGESA bios version from AMD. So UEFI/BIOS version can be important for ram compatibility. Thanks for the screen shot. I see ASRock is stating the kit as Samsung C-die.
