Question RAM compatibility/performance question, 3200Mhz RAM kit and motherboard on 2666 CPU?

[TheDefaultGuy]

Hi All!
Recently i was gifted some PC parts by a kind dude from Louisiana, so far ill be getting;
-Intel i3 10105F (from i3 7100)
-ASRock H510M-HDV/M.2 (from H110M)
-MSI GTX 1650 D6 VENTUS XS (from GT 1030 lol)
on its way from overseas (which im very grateful for btw, and ive yet to see if it all works, PSU and Storage are to be discussed) and
-ADATA XPG Spectrix D50 DDR4 3200Mhz (x2 8Gb) 16Gb kit in my possession cause i planned for an AMD build couple months ago, and it was on sale, but SHTF...life stuff etc.

I have skimmed through the Manufacturers site of the Motherboard and CPU, and the Motherboard says it supports 3200Mhz RAM speeds
while Intel says the i3 10105F supports up to 2666, and since I already have the RAM, I wanna use it.

And also there's the "QVL" stuff, which I didn't find my specific RAM in, but found its close similar, so I'm not sure what to do about that info.

so I'm guessing I could just run it all together?, like...the XMP stuff will take care of it all and run on the CPU's max speed and the RAM will be fine?, will I be good once I assemble it?, just plug and play type of stuff?, will there be issues? if so, what i could do? Thanks in advance for responses, be kind this is all new to me, im learning ': )

.the XMP stuff will take care of it all and run on the CPU's max speed and the RAM will be fine?

You might have to reduce the automatic XMP speed and manually set a different (slower) speed.

When you power on the computer for the first time, the BIOS will probably start the RAM at the JEDEC default speed programmed into the RAM's SPD (Serial Presence Detect) chip. For DDR4, this is normally 2133MT/s or 2400MT/s. This ensures a stable boot to start off with.

I'd probably advise installing Windows with the RAM running at stock JEDEC 2133 or 2400MT/s. Once you've got Windows running and it seems stable, then you can try XMP memory overclocking. You could jump straight in and set XMP immediately, but if you push the CPU too hard, your Windows installation might come to a sudden halt.

When you're ready to try XMP memory speeds, you can go back into the BIOS and select a higher speed above 2133/2400. This is where you might need to read the manual. Left to its own devices, the BIOS might try the highest speed of 3200MT/s in SPD, but this will probably be too fast for your CPU, which has a spec. of 2666MT/s.

Try to find an option in the BIOS for 2666. It might take a bit of searching, but it should be there. If 2666 is stable and survives a 2 hour test booting the computer up from MemTest86+ on a USB memory stick, you could try pushing up to 2800MT/s, then run another MemTest86+ full pass.

so there's the "QVL" stuff, which I didn't find my specific RAM in,

The Qualified Vendor List doesn't contain all available memory, but that's never bothered me. It's a guide, but you can usually plug almost any decent DDR4 DIMMs in and they usually work fine at JEDEC default. Extreme XMP overclocking is a different matter. You just have to experiment and keep testing until the system is stable.

Thanks for the response and info, i now know a gist of what I'm getting myself into, i will keep all that in mind once it all arrives

Also, one thing, i forgot that my RAM has RGB in it, will i be able to control it through normal means? like using just some random RGB control software? (for ex. ASRock Polychrome Sync) , or there's some constraints that i do not know of?, the motherboard doesn't seem to be the highest end, and it didn't mention any RGB stuff so that's why I'm curious about it, Thanks again for useful info.

It should run fine at 3200mhz. Just set XMP and enjoy.

Sorry, all my RAM is dull, boring, plain, ordinary stuff with no LEDs. I'm sure someone else can help.

I couldn't get my AMD 2600X to run with two DDR4-3000 DIMMs at stock XMP 3000MT/s settings, until I manually tweaked CL/CAS and relaxed the timings, despite the 2600X being rated up to DDR4-2933. Perhaps the 10105F rated at DDR4-2666 will be more tolerant running at XMP 3200MT/s settings?

You probably needed a bios update, or your ram didn't like AMD. I have never had an issue with even R5 1600's with 3200mhz Gskill Ripjaws, and Asrock B450 boards, myself, and I have built several of such systems. Intel tends to be less finicky about ram, than Ryzen, especially early Ryzen.

The 2600X mobo is on the latest (relatively old) BIOS. The original processor was a dual core A6-9500 APU, so I'm not bothered about extracting the last ounce of performance. I keep the 3800X and 7950X rigs updated whenever a new BIOS appears. I might consider a Threadripper in 2026.
