Processing questions about processors and memory
Processing questions about processors and memory
Hello. Forgive me immediately if the text is not accurate, English is not my native language.
I will get right to the point. I am currently selecting components for my new pc - for the first time. I started with a processor and bought an Intel i5-9600k. I started with the CPU and bought Intel i5-9600k. And then I started to choose the components, but I came across some questions that I would like to know the answers to.
1) The specification of my CPU says that it supports DDR4-266 memory. No matter how many articles I read, it is not specified anywhere whether my processor will work with 3000 Mhz memory. I know about the fact that the motherboard must be with a Z chipset.
From what I've read, I understand the following. In order for the processor to work with 3000 Mhz I have to set the XMP (ideally all processors support them) on the board, raise the FSB to the right frequencies. Is that right or something else? I'm also interested in how to convert FSB from Intel to more understandable units (Mhz, Gb/s) rather than "8 GT/s"?
1.1) This question is directly related to the first one, namely that the CPU supports memory bandwidth of only 41.6 Gb/s (this can be conventionally called frequency). I take it that I am increasing FSB - increasing the bandwidth?
2) It is also a question about limiting the CPU bandwidth. This means that without overclocking the FSB I can install - 2 modules 2666 in dual channel mode and get 41.6 Gb/s. The calculation is as follows: real frequency (1333) *2 (2 modules) * 2 (2 channels) * 8= 41.6 Gb/s. Is it true?
2.1) I have seen such questions on the forum, but I have not found a single answer. If I install 4 memory modules, will each of them take 50% of the channel? You mean 2 memory modules per channel? And so, if there is no overclocking, will I get the same frequency as with two cards, only more memory? In other words, I will not get any increase in computer performance?
I will clarify, I do not just want to know "yes or no", I want to understand these questions extensively. Thank you.
What kind of motherboard are you using?
Begin by checking the specifications provided on the motherboard. These details should outline which components are supported, such as the CPU, iGPU, GPU, RAM, and how they can be configured properly. Visit the manufacturer's official site to access the User Guide or Manual. Components are typically listed in a QVL (Qualified Vendors List).
Take your time reading thoroughly—include all notes and small details. Most guides will direct you back to the manufacturer’s website for further information, updates, and specifics.
Motherboards frequently receive revisions, so knowing the revision number is crucial. Also explore the manufacturer's FAQs and forums for additional insights.
Reading other motherboard manuals can be helpful; they offer practical examples and tips.
Keep a record of everything and align your build plan accordingly.
Thank you for your response. I haven't purchased any motherboard yet since I'm just reviewing the questions. However, I believe a 99% board with an Asus Z390 chipset would be ideal (it supports both CPU and memory overclocking). If you prefer a concrete example, the Asus PRIME Z390-A seems like a good choice. It’s likely I’ll buy this one.
Regarding QVL, I’m also familiar with this idea. All the boards I’m considering meet my theoretical requirements, and the CPU I already have is compatible.
I haven’t read the manuals (PDFs), but I’ve reviewed many board features and forums you mentioned. None of the solutions I found directly address my questions. The motherboard manufacturers usually don’t clarify details about the processor or its RAM connection, which is what I was seeking.
Of course, before buying the CPU, I studied the motherboards and explored the Z390 chipset and RAM options on Asus boards—most of them exceed my needs. That’s why I didn’t ask about the motherboard itself, as I already understand from those sources. At least for now.
And that’s why I think I focused on questions about the CPU and RAM, especially their compatibility.
Return to review the relevant component manuals (PDF files). You can examine what each manufacturer states about the parts—motherboard, CPU, RAM, GPU, etc. If the statements match, the compatibility is likely confirmed. Nevertheless, any product may undergo updates or revisions that could affect compatibility when details are examined. These modifications are often not clearly mentioned beyond small text like "*" or similar notes. https://dlcdnets.asus.com/pub/ASUS/mb/LG...V2_WEB.pdf [Note: Your English is acceptable, so I selected the English version. You may switch to another language if desired – it could be even more useful to clarify any language or usage issues.] The summary of specifications starts on page nine. Pay attention to the bolded references. Pages 1-4, 1-5, and 1-6 provide detailed CPU and RAM information. Print out the pages you need to review as you verify parts and organize your build. The diagrams and charts will be very useful for assembly and setup. For further guidance on overclocking: https://forums.
Thank you for your article and these pages. I thoroughly reviewed everything, yet I still couldn't find the answers to my questions. Apart from the overclocking on the specifications, I felt confident about everything.
You might have misinterpreted me, so I’ll rephrase my question. I’m not seeking a confirmation about component compatibility. My focus is on the following points. If you’re aware, I’d appreciate answering one by one. I’ll begin with this:
To boost the frequency of DDR4 memory to 3000 Mhz (provided your motherboard supports it), enabling the XMP profile is necessary. Here’s my concern: since my Intel processor (9600K) treats all memory above 2666 Mhz as overclocking, should I make any adjustments to my processor when using XMP at a higher frequency (above 2666 Mhz)?
This is the first question I have. I ask it because the CPU specs state a maximum throughput of 41.6 Gb/s (2666 Mhz).
Another point: if increasing RAM speed does indeed raise its bandwidth, would that be beneficial even if the processor still caps at 41.6 Gb/s?
My queries are now venturing into unfamiliar territory.
In general, a system's speed is limited by its weakest part, which acts as a bottleneck.
I'm also cautious about ignoring the specifics that are used to back performance promises, especially when comparing overclocking claims to actual results.
Understanding the documentation requires paying attention to both what is stated and what is omitted.
