Raptor Lake Settings Survey and Spreadsheet "Database"

[FlyingScot]

Welcome to the Raptor Lake Settings Survey and Spreadsheet "Database"

While no two systems (or CPUs) are the same, it is my hope that you will find this centralized information useful when comparing your own specific setup to those who have the same CPU - and maybe similar hardware. In addition to this objective, I have also provided an opportunity for Raptor Lake owners to periodically submit additional entries to the survey database when anything changes. If degradation becomes more of a widespread issue than originally anticipated then these periodic "field reports" should allow us to see these trends as they unfold.

Instructions for Survey Submissions
Once you're satisfied with your system's stability and performance, please follow the instructions below to prepare for your first submission to the survey database.

Please download the attached Survey Guide.pdf. This guide has been designed to give each survey respondent a chance to gather all the relevant information ahead of time. This is an important step. The last two pages of the guide describes how you can make immediate use of the survey results, either before or after you complete your online entry.

In addition to the many questions in the survey, you will find a section (Section 2) that asks for performance related data. I have selected Cinebench R23 for this purpose. However, Cinebench R23 is only one small snapshot of performance and I realize will not necessarily be indicative of gaming performance, etc. In fact, as our recent testing has demonstrated, some "undervolting approaches" are much better suited to all-core CPU workloads (like Cinebench R23) than those favoring lighter, non all-core workloads, such as gaming.

How is your PC now? Is it stable after further testing?

Sorry, I have been back in a long time. Yes, it's absolutely rock solid. So far anyway. I ended up bumping the offset up by 5mv. So whatever I was in myast database entry, I'm .005 higher than that. I also raised the ac load line from 5 to 10. Finally I adjusted avx offset for auto to -2.

Of course, it does run hotter now under heavy load. I've hit 90 a few times for a second or two. But that's fine, I haven't even seen the calculator pop open since making those changes. And I only lost about 50 points or so in R23. Maybe a little more. Also fine with me.

Checking in Still have a few z790 boards laying around and traded the KS in on a 9950x3d. How goes stability on the latest microcode and 14900/13900 k/kf/ks units current date?

I tried messaging you directly but it kept saying it was flagged as spam, I need some help if possible any help would be really meaningful. I have had a voltage cap and a pretty decent undervolt on my chip for 90% of the time I used it, it's the F variant of the i9 14900 with a thermalright phantom spirit so it runs at lower wattage as an F variant and my motherboard is an msi b760-vc wifi 7 board that has limitations with the VRM's in terms of how far it can push my i9 so I have kept the power limits between 165-219 watts at peak, I mostly game, I have a thermalright phantom spirit and very good cooling in my case, I usually don't let my cpu go above 78-85C and my vrm/mos temps don't go above 76C, my quesiton waws about IA CEP, I can not for the life of me figure how how to keep my chip running at a decent temp with it on, It's stable when it's' on but the temps are 10-15C higher than they are with CEP disabled and undervolted, which makes sense, lower voltage = lower wattage, my question was how can i properly undervolt this chip with IA CEP without triggering CEP which initiates clock stretching severly degrading performance? From what I understand it has to do with the vcore and the vid voltages needing to almost match while under load (does it matter if they match at idle?) I have adjusted my LLC from settings 1-8, used various liteload modes including Advanced liteload setting custom AC & DC loadlines, it is the Loadline calibration's (LLC) resistence in MOHMS that needs to match the resistence of the liteloads ac and dc loadline's resistence?

I honestly would pay somebody right now for some help with this. I haven't experienced any degredation issues, I am currently running 0x12b microcode, I haven't upgraded to 0x12F because my motherboard doesn't have a dual bios and it doesn't have a flashback feature so flashing is risky and scares me a little bit. I don't believe degredation has occured because this board probably was not meant for going above 219 watts without the vrm temps going too high, it is a board that came with a prebuilt I got from MSI. I was wondering if you could help me by explaining the importance of IA CEP and why you would need it, even if you have strict Power limits, current limits and voltage limits running lower voltage. I was also curious about the VMIN issue that the 0x12f microcode patches and if I absolutely need to flash my bios, I have been babysitting this chip since I got it out of paranoia with a hwinfo64 panel on a secondary display monitoring everything while my system is on, I usually turn my pc on maybe run some battlefield 6, use chrome for a while, it might idle an hour or two here and there, then I shut it down.

Any help would be amazing, I have seen some of your posts and they were really helpful. Thank you for your time.

Well, MSI recommends to not to update bios if the system has no issue for the very same reason. I would have adviced you to stay on latest BIOS even if your system is fine but as you mentioned you mobo msi b760-vc wifi 7 has no bios flashback feature then there is a risk of bricking the board if the BIOS update is interrupted.

I do have a detailed guide on the BIOS settings for a 14900k but for MSI Z790 Carbon Wifi mobo they might or might not work on your mobo. I would not adivice you to play with BIOS settings if you dont know what you are doing in the first place but if you still want to try them then visit (https://forum-en.msi.com/index.php?...si-z690-z790-motherboards.400345/post-2330571)

If you are worried about lifespan of your 14900f then atleast set the VR limit to 1.350 or 1.400 if it downclocks way more. This will give you peace of mind but processor might not boost to 5.7 or 6.0 unless other bios settings are tuned.

Or
just use intel defaults and cap the frequences to 5.7ghz for p cores and 4.4 for e cores with 1.400 vr limit and you good to go. Good Luck
