What would occur if you set up DOCP manually?
I've noticed frequent restarts when starting up to the desktop on my latest Windows 11 installation, along with some post-boot freezes. ChatGPT suggested disabling DOCP, which resolved the problem but now my RAM isn't operating at its full 3200MHz. It recommended leaving all DOCP settings auto and setting a lower safe limit of 3000 MHz manually. What are your thoughts on this? I'm aiming to use the entire capacity of my RAM and would like to adjust these settings carefully without losing performance.
Before diving deep into these adjustments, keep in mind it’s unlikely you’ll notice a significant change in real-world applications. You’d likely observe minor variations in memory benchmarks, while other programs remain unaffected. A few specific scenarios come to mind, such as ZIP file compression or using a CPU instead of a dedicated GPU. Overall, the total amount of memory has a much greater impact than the clock speeds.
Memory performance is quite complex. It involves not only the memory modules but also the CPU’s memory controller and the motherboard design. It’s wise to review compatibility information on the motherboard manufacturer’s website before purchasing memory, as someone else has tested it for you.
Ultimately, you’ll experiment with these configurations until you achieve stable maximum speeds. DOCP and XMP are forms of overclocking that set values optimized for most users; there are many other settings to explore. Try running memtest86+ to verify stability—aim for at least one clean pass. This kind of testing is far more rigorous than typical usage scenarios.
It all comes down to how much time you’re willing to invest in learning memory settings or if you prefer using the system now that it’s reliable.
I've been experiencing random restarts when booting to the desktop on my new install of Windows 11 (and a few lockups at post).
When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time. Since you've stated D.O.C.P, I'm assuming you're working with an Asus motherboard. If you've installed the OS while leaving AMD's E.X.P.O/Intel's XMP enabled, then that was your error. Speaking of errors, where did you source the installer for the OS? Did you install the OS in offline mode?
What's the thoughts on this?
There's a saying,
what the mind does not know, the eyes cannot see
. ChatGPT would've scrubbed info from another source, that doesn't transplant over to your platform's predicaments, much like how the OS sources drivers it thinks is right for your platform but often times leads to BSoD's. That being said, you either enable the ram kit's baked in profile or manually set all parameters for your ram in BIOS, provided you know what to key in. Wrong timings can lead to instability issues.
I want to get full capacity from my RAM
Capacity is the amount of ram installed and at your disposal. D.O.C.P entails ram timings and speeds, they are two different things.
I reversed the process on my 3800X system in 2021.
I own two 32GB RAM kits (two 16GB units) from Corsair Vengeance DDR4-3000, totaling 64GB.
By chance, Thaiphoon Burner confirmed they offered "matching" memory chips from the same maker, though they weren't from the same category and would likely have timing variances.
Despite these issues, my rig successfully launched in Windows 10 at 3,000MT/s and passed multiple MemTest86 tests.
For testing purposes, I updated my Asus motherboard BIOS from DOCP 3,000 to DOCP 3,200; the overclocked RAM still cleared MemTest86. I returned to the original 3,000MT/s after a short period and it's functioning normally up to that point.
Keep in mind my DIMMs were rated at just 3,000MT/s when paired together, while I had two separate pairs, which typically need slower clock speeds. In fact, my four DIMMs operated faster than their rated limits for two of them.
This isn't a strategy I'd advise, but sometimes outcomes are fortunate.
I recommend trying it yourself, but always run several full MemTest86 cycles. If you encounter any issues, adjust timings or lower the speed.
It's crucial to avoid memory errors that could damage essential files on your operating system or data drives. That's why I use ECC RAM in my two TrueNAS Xeon servers. I take calculated risks with certain systems, but not all of them.
I discontinued the 3800X setup in December 2022 and moved to a 7950X paired with two 32GB Kingston DDR5 modules, operating at the standard JEDEC 4,800MT/s because the XMP settings matched.
For your case, lowering the DOCP speed might improve stability in theory, but don't rely on it. Good luck.
You can explore SPD speeds using tools like Aida64, ThaiPhoon Burner, CPUZ, etc., and compare them with the DOCP values listed in the BIOS.
The simplest way to boost stability is to add a few extra clock cycles to the CL/CAS settings, which slows RAM slightly but can resolve issues.
On the applications I use—such as DaVinci Resolve—faster RAM speeds on Ryzens don’t significantly impact performance, though additional memory can still help. Gaming scenarios are different.
