After installing the new RAM modules, the computer starts up more slowly.
Hello everyone,
I recently installed two new RAM modules and noticed my PC boots more slowly. It powers on normally but takes a few minutes to enter the boot screen. When accessing Windows or BIOS, all modules are recognized and it displays 64GB with a speed of 6000MHz. The motherboard is an ASRock Z790 PG Lightning. The RAM includes a Fury Beast 32gb kit and two Fury Renegade modules, each 16GB.
The installation was done as follows:
SLOT A1: KINGSTON Fury Beast KF560C36BBEK2-32, DDR5 6000MHz, 2x16GB
SLOT A2: KINGSTON FURY Renegade RGB KF560C32RSA-16, DDR5 6000MHz
SLOT B1: KINGSTON Fury Beast KF560C36BBEK2-32, DDR5 6000MHz, 2x16GB
SLOT B2: KINGSTON FURY Renegade RGB KF560C32RSA-16, DDR5 6000MHz
Is this typical for the first few attempts? Or are these modules not compatible? Perhaps I should consider purchasing additional ones. I understand it’s normal at first.
Thank you in advance.
What BIOS version are you on for your motherboard?
Which ram kit was the one you picked in the first place? have that, return the new kit and source the exact same ram kit as your initial kit ion your build. Thumb rule with ram upgrades, treat them like you would when buying a pair of shoes, you need to buy a pair...not a single shoe. Mixing and matching rams often tends to instabilities/troubleshooting/grey hair moments.
BIOS version is 7.02
First unit was a Kingston FURY beast, slot A1 and B1, this one was a 2xkit.
Fury renegade is RGB, single stick, I purchased two since a 2x kit wasn’t available.
They’re identical: both are KF560C32RSA-16.
I own one FURY Beast kit from the manufacturer – 2x16GB
and another kit made by me with 2x16GB of KF560C32RSA-16.
EDIT: Both memory specs match exactly – KF560C32RSA-16 and KF560C36BBEK2-32.
Same CL (IDD), tRCmin, tRFCmin, tRASmin, UL Rating, Operating Temperature, Storage Temperature.
Ram is sold in kits for a specific purpose.
A motherboard needs to handle all the RAM according to the same voltage, case, and speed requirements.
The internal design is tailored to the capacity of the kit.
Ram from the same manufacturer and part number may vary in manufacturing over time.
Certain motherboards are particularly sensitive to these changes.
This becomes more challenging when multiple modules are used.
It’s essential to match the RAM for optimal performance.
I believe the issue arises because the motherboard takes longer to identify a suitable setting.
Check cpu-Z to view the current settings and adjust them manually in the BIOS.
You should likely notice an increase in RAM voltage.
Try running memtest86+: it boots from a USB drive without using Windows.
You can download it here: Memtest86+ | The Open-Source Memory Testing Tool
Memtest86+ is a free, open-source, standalone memory tester for 32- and 64-bit systems (supports UEFI & BIOS)
memtest.org
If you complete a full scan with no errors, your RAM should be functioning correctly.
Performing additional passes may reveal problems, though it requires more time.
Unless you strongly suspect a RAM problem, it’s probably not worth the effort.
Thank you..will try it out later.
One other funny thing is happening, as this is RGB stick both RAM start by cycling colors.
Then when I enter windows one changes colors as I change it with FURY CTRL or ASROCK tool, along with fans, but other locks on one color and stays like that till I restart the PC.
I suspect that maybe I need fresh Windows install because something else is controling the color or can the issue be somewhere else?
If I don't run color changing software, both RAM sticks will change colors till I do.
The assessment lasted approximately 30 minutes. It was successful with no mistakes recorded.
There will likely be hidden variations between the kits such as small controllers and the ICs themselves, which won’t appear in a standard spec sheet. These are some of the main reasons RAM sticks are offered in different package sizes like 2x, 4x, 8x, etc., even if the part numbers match. If you have four individual sticks and attempt to combine them, they might not function together. Some kits could contain different batches of ICs or controllers, or even slight changes in manufacturing details between revisions. It’s also worth noting that manufacturing tolerances and solder quality differences can affect compatibility. My suggestion is to try another 2x kit from the original RAM or consider a 4x kit if needed. Even then, if the CPU controller struggles or the motherboard isn’t compatible, it might not work. TLDR: RAM kits come with too many variables, making a matched kit or a 4x kit a simpler solution.
The test ran successfully with specified RAM configurations, timings, and voltage levels. If needed, a bit more voltage would help. The motherboard will only accept the given settings and won’t look for alternatives. I’m wondering why I’m even trying to boot? Maybe using sleep instead of hibernation would be better—it keeps the PC and monitor in a low-power state close to full shutdown. Sleep/wake takes only a few seconds. By the way, I haven’t turned off the system in 14 days.
I don't agree with that approach. Turn it off when not in use and turn it back on when needed. The thousands of hours spent in sleep mode at 2-10w add up. Neither attitude has been clearly proven superior, but please correct me if I'm mistaken. For me, sleep mode has caused problems, so I avoid the issue by not using it.
Thank you all for your assistance.
The issue seems to have improved. I tested it yesterday with 8 power offs and ons and everything worked fine. This morning it was also functioning properly.
I usually don’t power off the PC at work for more than 25 days, but I do at home since Windows starts behaving oddly when left on too long.
Previously it was similar to your experience—though not to shut down my PC, it’s better if you do so. As I mentioned, Windows tends to act strange.
The only remaining problem now is with the RGB lighting; I plan to reinstall Windows this weekend and hope it resolves the issue.
Another odd occurrence is happening: both RAM sticks start cycling through colors when I use FURY CTRL or ASROCK tools. When I switch windows, the color changes too, but other locks stay fixed until I restart the PC.
I think a fresh Windows installation might be necessary, as something else could be controlling the colors, or maybe the problem isn’t here.
If I avoid running any color-changing software, both RAM sticks should stop cycling colors.
Thanks again for your help.
