Is there any point on getting slow speed/JEDEC CUDIMM?

Now near to Arrow Lake release manufacturer barely had CUDIMM out. The one they released now is like 6400 and not to mention with small capacity which we can easily and I assume cheaper to get with regular DIMM.

So my question if there is benefit to get CUDIMM slower than say 7200 regular DIMM which I think sweet spot for last gen Raptor Lake?

Need help removing lock for i9-9980HK (Asus Zenbook Pro Duo UX581GV)

This is the state of my CPU:

https://preview.redd.it/mj7tcxwa7mvd1.jpg?width=2560&format=pjpg&auto=webp&s=b2fe19498b66cacf271263414fead518e1305808

This has been a problem for a long time. Changed paste a few months ago.

Fans also never reach 100% and I couldn't find any way to be able to control them. The only time they spin at 100% is in myASUS fan test (very frustrating).

The only thing left to do I guess is to undervolt it, but ofc it's locked.

Found this great guide - https://www.youtube.com/watch?v=0gMmfexcjNs&t=401s

The problem is that I am stuck at identifying the oc and cfg lock because Universal BIOS Backup ToolKit 2.0 does not work.

First of all, disabled defender and ran it as admin and I get an error that I need to run as admin. Anyway the program opens. Secondly, I have to select the amount of RAM but it only goes up to 16GB (I have 32). If I click read it does not work.

So I am stuck.

i7 14700 won't stay at max MHz

TLDR; Why does my i7 14700 throttle to 2750MHz and 65w in OCCT stress test?

EDIT: Thank you u/oomenya333 & u/stoicfruit777. Following their input I first ran an old saved civ game. The game ran fast and I could see the clocks maxed out. I then jumper into bios and played around with LDPL. Results can be seen.

75W LDPL

100W LDPL

END EDIT.

I realise this isn't technically overclocking but I thought it a suitable place to put it. I'm a bit of a reddit noob and this is about as much as I can manage :D

Yesterday I built a new system.

MB: MSI Pro Z790-A Max Wifi

CPU: i7 14700

RAM: DDR5 5600

GPU 4070 TI Super

I'm still waiting on watercooling parts, GPU block and LGA 1700 backplate for CPU block. I run these for fun and silence, not because I like to run this to max all the time.

Despite being on stock air cooler I still wanted to get some idea of performance. However when I run OCCT it will go to 5400MHz and 219W for a couple of seconds then throttle back to around 2750MHz and 65W.

My previous build was an i7 8700 which would sit at 4600MHz and 110W during the entire test.

I do get a thermal event flag at the start of the test and I am also seeing power limit flags on all cores.

Do you think this is being caused by the stock cooler and the thermal limit, or is it power delivery, or something else maybe?

i7 10700k, have I hit my chips limit?

TLDR: I'm doing pretty good at 5000MHz with a 50 multipler in my bios. A 51 multipler causes some issues but more importantly the clock speed goes down in OCCT.

5.0ghz I'm stable at 1.35V on my cpu. AVX I've set to 0. The TTL is 5/8 on my z490 asus board. I could probably go lower as I haven't really tried it, but my temps are in the 60Cs to low 70Cs after the full test.

Getting the extra 100MHz is bogging my mind. I've tried getting my Vcore up to 1.38 to stabilize, and I can get into windows but the cpu is at 4950Hz and hovering in OCCT, where when I was at a 50 multipler it was a stable 5000MHz.

Another thing that's concerning is my on board ethernet goes out within about 2-3 minutes when I do any kind of overclock above 4700MHz. Everything will be stable except for the network. Unsure what could be causing this but I haven't maxed out my TTL or Vcore so I don't think it's fried. The mobo is a asus z470 gaming plus if that means anything.

Am I tapped out for the chip or is there more I can do? Thanks!

Noob Overclocker Questions; Overclocking a Monitor from 100hz to 120hz

I've heard that doing drastic overclocks on monitors is not safe for the monitor, but I feel like a 20hz bump is not that drastic. I'm trying to see if I can't get my Xbox SS to detect my monitor as a 120hz monitor so that I can enjoy higher refresh rates on games that support it, but with my monitor being 100hz only, it gets capped at 60hz on xbox. I have two questions; Is it feasible and safe to overclock a 100hz monitor to 120, and will an Xbox console detect that the monitor is running at 120hz?

Trying to lower the voltage of my OC 12700k

Long story short, my CPU voltage is at 1.43 V and it’s very stable at this at number (12700K)

I mostlot don’t game but I do music production stuff which is why I want to maximize my single core score (as most DAWS still don’t take full advantage of multi core processors)

it’s at 5100mhz and I can get it to run 52 if I increase the LLC to 6

any time I try to reduce the voltage it crashes either with a black screen or blue screens after trying to bench it

at this point I’m not sure what to do

im aware that high voltages can wear on a cpu so I do want to see if I can get that down

Possible Boost Overclocking issue on my Zotac RTX 2080 AMP?

Greetings I am having an issue with my computer blackscreening temporarily and coming back, games crashing randomly without warning or freezing, usb shutting off and failing; bluetooth randomly disconnecting till i restart. I have run a myriad of tests and cannot determine the overall cause. I have recently come to learn about Factory Overclocking. When I check my Zotac card https://www.amazon.com/ZOTAC-GeForce-256-bit-Graphics-Backplate/dp/B07GG9L5X1?th=1 I noticed that it has a factory boost overclock (i didn't know what AMP meant when i bought it, I just wanted the 3 fans for cooling) Is the card failing when it kicks into boost overclocking and is that what's causing all my issues?

RAM: 32 GB
CPU: Ryzen 7 1800X
GPU: RTX 2080

Stability tests

Hi,

I’ve applied and undervolt to my 14700K and originally tested in cinenbech R23 for 30 mins however read that this isn’t the best way to stress test.

I then switched to prime 95 for another 30 minute test and on my first test I blue screened , I then thought I’d try again and see if I get another blue screen. The 2nd torture test run was successful for the whole 30 mins with no issue.

Is this too early to say that my undervolt is stable? Or do I need some more work on it due to the first test blue screen?

What would you advise?

5800X3D + RAM timings for Factorio

Hi, I tested many configurations and do benchmarks using https://factoriobox.1au.us (due my one game is Factorio and nothing other)

Many reboots and configurations checks produced these OC stable (without any WHEA)

CPU

ZEN Timings

Of Course CL Timings are bad but I do not know how to do it better (changing into 15-15-15-15 cause crash that need bios reset). RAM configuration is 4x8GB. Most time I spent into reducing tRFC to be as low as possible (directly boosts performance in Factorio)

My performance tests are Ok, but someones can go higher on te same setup - so I think that i some messed up with timings.

Any Ideas? any Advice? Factorio DLC out at Monday so I have time to OC again :)

Anyone fancy helping me?

So I've got a gaming pc that I use for sim racing so I want to extract the best of it that I can. And my few mates I play with are telling me that overclocking and possibly undervolting both cpu and gpu and tweaking my ram settings should really help with performance. I haven't tuned a computer since ryzen 1700 all core over clocks etc and I'm just looking for some help to extract the best from my system if that's all possible?

A lot of guides I see I dont have some of the suggested options to adjust.

I have the following system ;

MSI x570 a pro motherboard Ryzen 5900x cooled by a Arctic liquid freezer 3 360 aio Evga 3080ti on air 32gb (2x16) trident z neo 4000mhz ram with xmp enabled. 1400w thermaltake psu titanium rated Corsair case and basic other equipment.

Everyone keeps telling me to disable xmp and get my infinity fabric to 3800 or 3733 and set the ram 3800mhz or 3733 and really tighten the timings and I should see a noteable improvement and that 4000 is slowing me down. I have tried to follow a guide but I don't have some of the options that other videos show on the infinity fabric for instance. Has anyone got any advice? I've tried ryzen ram calculator upload my xmp and use it to calculate timings but it tells me that it's not compatible with what I'm using and I don't really know why.

I'm also being told that my cpu (currently peaks at 4.9 and is there quite often never goes above 52c) shud be tuned using something called curve optimiser and precision boost overdrive and i would likely get higher clocks and fps. Can't figure that shit out at all lol. The reset cmos and battery are directly under the gpu annoyingly.

Same with gpu, im being told I should undervolt and overclock and I shud see more frames from it but idk wtf I'm sposed to do to do that every video I watch has different information lol.

Can anyone help me sensibly at all?

I7-7700K w/ Z170-Gaming K3-CF, Manual Vcore doesn't seem to do anything

I am currently trying to overclock my 7700k to 4.8GHz, but when I set my Vcore 1.25V and boot to windows to open Hwi to check voltage and temps, the reported Vcore is at 1.3V or more. I have disabled voltage optimization, tried LLC at both auto, standard and high, disabled EIST and tried to find anything that had the word "dynamic" or "adaptive" in it, but it still doesn't work as I want it to.

Does anyone have OC experience with this gen cpus or hopefully this or a similar Gigabyte mobo? Any suggestions would be deeply appreciated!

Intel Microcode on Asus Profile

I would like to know if the microcode (0x129, 0x12B) works only with the Intel profile or does it also work if I change to the Asus profile?

I would like to lightly overclock an i9-14900k, to 4.8 or 4.9, and I think it's easier to make these changes using the Asus profile. But I don't know if the microcode would work in this case.

help overclocking 4xS8B on Z370+8700k

been messing around with faster & faster kits. currently trying the following setup:

Maximus X Hero WiFi Z370 / 8700k / 4x Patriot Viper Steel 4400 cl19-19-19-39 1.45v

very new at this, but I've read the DDR4 OC guide a few times. already set up a baseline, and now I'm struggling to nail down 4000mhz cl16-16-16-36 even at 1.55v with VCCSA/VCCIO at 1.3v

closest I've been able to get is 3900mhz cl17-17-17-37 1.5v (VCCSA/VCCIO 1.3v), which posts & passes memtest86+

haven't bothered tweaking my secondaries & tertiaries yet. am I missing something? I'd think surely better can be squeezed out of four b-dies on a t-top but maybe I'm wrong!

Need help with ancient hardware

Mostly doing it for fun so I’m not too worried but this problem really annoys me. It’s LGA1156 (P7H55M-USB3 w/ Xeon X3460 and two dual rank 4gb sticks) and almost any alteration to the OC-related settings causes it to shut down on Windows loading screen (not even a BSOD usually, just shutdown as if the power was cut). It has a year old MSI tier C PSU that had no issues powering Vega 64 and RX 5700 so I doubt it’s at fault. Observed the same behavior on a different P7H55M with different CPUs (i5 760, i3 540) and 2 different Win10 installations.

I threw in a Linux SSD and Linux seems to be less prone to it (sometimes it boots successfully when Windows doesn’t and even runs some games), however it still happens sometimes. I found that enabling LLC almost guarantees a shutdown on boot, but even without it something feels wrong, even raising the BCLK from 133 to 150 makes it very unreliable. But if it manages to boot, it usually works fine, even if it shuts down on OS loading 10 times with the same settings prior to success. Are 1156 motherboards simply failing from age at this point? Issue feels weird to me. And I can’t find any reports of it really, it’s usually people having BSODs.

Undervolting 14700F

Hi all, i want to undervolt my 14700F, my objective is to make the chip run a tad cooler and reduce the overall voltage and spikes, no overclocking since the chip can't do it and i am also ok with its stock performance.

My problem is that it's the first desktop i've had since a ton of time so i've never dealt with AC loadlines, i've followed Buildzoid video and while i think i understood a bit of what he explained i do not want to try to mess with the loadlines to not make the CEP trigger, nor to disable it because it may also act as another layer of protection from overvolting.

I am asking here because you guys have surely a clearer idea than me when CEP triggers, as i am not entirely sure that it always triggers. With a vcore offset (my board has no adaptive + offset) of -0.08 and all the other settings untouched (Intel default + loadlines on auto) i experience clock stretching, more precisely i lose 400 mhz on all E-cores on full load, checking with Hwinfo + CB23 by comparing active clocks vs effective clock (and also lose 2k points or so). So i tried to change the offset a bit, and i found that at -0.05 i do not see any clock stretching even with CEP on.

Actually i gotta say that the scenario where clock stretching was most evident was when the cpu was sitting on the base clocks in BIOS (UI was lagging) and when multi core was involved (cinebench). But at -0.08 also my P cores couldn't reach full clocks (cep shaved off 100 mhz), they would be able to reach them at -0.07 but the base clock was still affected, and it was still evident (to a lesser extent though) on the bios. An adaptive offset would have helped a ton on being able to not trigger cep on lowest clocks but my msi b760 P II board on latest firmware doesn't seem to have that option, while on a global -0.05 offset it seems to not trigger CEP on all the scenarios i've tested (base clocks and turbo boost).

So i was wondering is this scenario possible or am i hallucinating in an attempt to not touch loadlines? The reason i do not want to touch them is because i honestly never did that, it's a new computer, and while i mostly understood what Buildzoid said i still do not feel enough sure to go with it because i really am pretty ignorant on the whole thing, i need to get more confidence before tinkering with it, i do not want to change numbers without fully (or at least mostly) understand what i am doing.

But i was still curious if CEP may not trigger in case the vcore offset undervolt is very slight like mine, because if it doesn't i may call it a day for now since my main objective was to reduce peaks and be on the safer side with the chip health without messing too much and changing too many options. The CB23 scores are sameish as stock voltage, i've checked several times, and it's also able to reach the maximum effective clock (5389 mhz or smth) on single core applications. But i still wonder if it's my brain tricking me or this thing may be actually possible and maybe the board is still giving enough voltages for cep.

Why is extreme LLC bad?

I was watching buildzoids video about how LLC works and I'm learning the super io chip is trash for reading vcore and VROut at the voltage regulator is much better for reading vcore. He also mentions that using extreme LLC is worse than high. Can anyone explain why this is in greater detail?

I would have though extreme is better since there's no vdroop at all. For example if i set the vcore to 1.3v and let's say with high LLC under load the vcore drops to 1.25v that could make the overclock unstable.

But if i use 1.3v at extreme LLC, the voltage underload will be 1.3v.

Yes i understand the spikes will be higher, but wouldn't that be better than having to bump the vcore up by 0.05v and running 1.35v with the EXPECTATION that it will droop to 1.3v underload?
