RAM and CPU clock speeds in Bios compared to CPUZ
RAM and CPU clock speeds in Bios compared to CPUZ
Okay so very new to building PCs and setting everything up in bios. Previously just got prebuilt gaming rigs.
Laat week I built a new gaming PC (my very first yay!) but I have some confusion...
I used AI Suite to OC (after setting the XMP profile I). Well I got a stable AI OC of 4900mhz (i9-10850k). I wasn't comfortable OCing the CPU manually, so I was just looking for a stable 24/7.
Anyways, when I go to the bios EZ-Mode (asus uefi) the XMP profile is set to disabled. The right side of uefi reads "AI Overclocking" and its on "AI Optimized"....in the top left corner it shows "information" and I still see my i9-10850k at stock 3.60ghz. Then it says Memory: 65536 MB (ddr4 3600MHz).
BUT below that it says DRAM Status as Dimm A1: G-Skill 16384MB 2133MHz. Dimm A2: etc..B1 etc.., etc... all four DRAM status reads stock 2133MHz.
Like I said...I used AI suite to OC. The XMP profile is on "disabled"...is this because my OC was AI optimized? I want to make sure my RAM is at advertised speeds of 3600MHz.
On "Advanced Mode" in bios on the right side under hardware monitor it reads CPU/Memory and says Frequency 3600 MHz and DRAM freq 3600 MHz.
This seems conflicting to me because EZ-Mode lists my DIMM slots as stock clock speeds of 2133mhz under status but in tbe other areas it reads the advertised speeds of 3600. Which one is the one its actually running at? and all spots in bios show my CPU as 3600MHz instead of 4900...does the bios not show OC'd speeds?
Also...fwiw I used CPUZ and the core cpu clock speed is 4900 and the memory is reading 1800mhz.
Since its DDR I double that 1800 right?
I just wonder why the bios shows RAM speed in some areas as 3600 but dimm status as 2133. Bios is really confusing me lol. And nowhere in the bios is it reading anything other than my stock CPU speeds, however even in task manager, just like CPUZ (and HWinfo) it's showing 4900mhz so I
think
the cpu oc is fine?
Really sorry these are probably super dumb questions but I'm trying to learn. I would have expected AI overclock to keep my XMP profile enabled..especially considering CPUZ shows (under SPD tab) SPD Ext: XMP 2.0
Really strange and confusing. This is however, my first week ever looking at the bios in my whole life, so excuse the ignorance plz!
Thanks so much. Full specs listed below;
i9-10850k
Asus ROG Maximus XII Hero
NZXT Kraken Z73
64gb Trident Z Royal @ 3600Mhz
MSI RTX 3080 Gaming X Trio
EVGA Supernova p2 1000w
Lian Li PC-O11 Dynamic
Hi

and Welcome to the Forum
What your doing is trying to interact with Bios using AIsuite and also possibly making changes in Bios.
I know it's pretty looking software but get rid of AIsuite and only Overclock in Bios. Undo any Overclocks and clear your CMOS. You have a very good chance of Bios corruption with what you are doing.
Learn your Bios and check out some vids and guides specific to your motherboard Bios and chipset.
Here is one of many that will help:

Go by Cpuz and increase the dram frequency rate.
The reason bios displays RAM as 2133 in certain areas is due to default behavior (SPD - serial presence detection), which changes once XMP is activated to support advanced RAM profiles beyond standard settings. Every RAM module must support standard modes so the motherboard can recognize and operate them correctly without requiring complex configurations (plug and play).
Using Ai suite temporarily alters bios settings during Windows sessions; settings should revert to normal once the session ends, meaning you’ll boot into bios again without Ai Suite interference.
Enable XMP directly in bios yourself instead of relying on Ai Suite. The same applies to CPU overclocking—carefully monitor voltage and temperatures. Keep track of safe voltage levels, particularly when the CPU is actively working while Ai Suite compensates otherwise.

Even if it's not exactly your MB, CPU, and RAM combo, the principles are the same.
Don't try to jump to your max target frequency in one hit but in 200MHz at a time then stress test for stability.
It takes time and patience to reach your MAX Overclock.
Remove Ai then simply apply the default settings in the BIOS. You don't have to perform the physical CMOS reset process; applying defaults restores the CMOS to its standard configuration.
Wow, you're really great to help! I'm going to read and watch everything I can about manual overclocking so I can replace this AI stuff. Thanks a ton!
