Issue with Corsair Vengeance RGB PRO not achieving 3600MHz frequency.
Hello Guys, im back here again asking for help with my Corsair RAM kit that i have bought a year ago. The situation that i notived it now was tht i had an B-Series chipset before, a month ago i upgraded to a Z370 Chipset and didnt think about it too much. Today i did a BIOS flash to AMI BIOS 7B44v1B3 Beta on my MSI Z370M Gaming PRO AC because it added support for resizable bar and im getting a 30XX Card soon. Decided to do some RAM XMP Over 3200MHz and even 3333MHz Fails and EVERYTHING above! Now my question is if it is the RAM (i heard of corsair binning issues) my RAM Controller in the CPU (i7 9700 non-K) or the fact that im running 4 sticks. Messing with the timings to CL16/17 works tho. All system info: CPU: Intel i7 9700 GPU: RTX 2060 Watercooled with custom G12 modded bracket/X53 RAM: Corsair Vengeance RGB PRO 4x8, SKU Number: CMW32GX4M4C3600C18 Running on 1.356V Mobo: MSI Z370M GAMING PRO AC (Beta BIOS 7B44v1B3) (didnt work on stable BIOS too so not BIOS fault) PSU: Corsair RM 850 Case: Corsair 5000D Airflow Fans: 3x Corsair LL120, 4x Noctua A12x25 (On Rads CPU+GPU) Samsung EVO Something SSD's 1x 1TB nvme 1x 2TB nvme 1x Toshiba 2TB HDD Thats everything i guess Just wanted to say again, the RAM XMP DID NOT work on a STABLE BIOS before too so thr Beta BIOS is NOT the fault. Thanks for your help!
It might be a Corsair problem. Check Thaiphoon Burner for details and use that info to customize it. This is Thaiphoon Burner.
Run each stick separately. Corsair has known issues with their RAM, though it doesn't impact older Intel systems (likely Ryzen and possibly the 12th gen, but uncertain about later models).
Increase the voltage slightly, Ryzen 2000 and 3000 often require 1.37V to reach 2866/2933 occasionally.
The issue with XMP stems from manufacturers varying their approaches. Some simply copy the primary timings while keeping tertiary and secondary on Auto, others tweak all settings. With your Micron E-Die chip, you might run a voltage test if the problem lies in power levels. Your RAM can operate at 1.5V continuously with minimal airflow, which is enough for extended testing even without airflow. You could raise the voltage to 1.5V and attempt a brute-force test. If successful, it suggests the RAM settings are affected by voltage—possibly due to tight timings or excessive clock speed for XMP. LLC configurations could also be the culprit, as they might reduce voltage enough to cause actual operation at a lower value. If that fails, the CPU memory controller might need adjustment of its voltages and parameters. Four 8GB modules should work fine as they are single-rank modules.
Just steal this 3800 cl14 ballistix profile and see if it works, having an oc profile you can reference is very useful but since this is micron rev e its very consistent so im pretty sure itll at the very least post but wouldnt be surprised if it is plug and play, may aswell get a performance boost while you are fixing your issue For adjustments if it isnt just plug and play (consistent but doesnt mean there is no variance per stick) try a voltage range from 1.5-1.6v which is the easiest adjustment you can make, if you start needing ~1.6v id suggest cutting the cas latency to 15 because it really doesnt make that much of a performance diff and usually can cut your voltage requirement by quite abit, for this kind of freq seems more ideal to be running ~1.4-1.5v just because its slow 3800 and so your rams are more stable since more thermal headroom, also the slower the speed the less sensitive these ics become to temp Not advisable to go >1.5v w/o fan due to heat, not advisable to go >1.7v for the imcs sake so it doesnt degrade (rev e dont degrade with volt), btw youll only start needing 1.6v+ for 4600+ cl18 shenanigans so thats why i dont reccomend running stupid volts for low freq unless you time it really tight like you can on bdie
