Intel I9-13900k base speed oc

Hello guys I'm looking for any tips and ideas to overlock my Intel i9-13900k base speed to at least 4.5ghz + is it possible and could be stable ? I have be quite 360 aio water cooling system and 1000w PSU and z790 MSI gaming plus mainboard

Is anything I need consider before doing it if so maybe someone can share some bios settings for it?

For people who couriers why I need to do that so answer is I need that first kick of speed on as validator ( crypto ) cos so far AMD's with speed of 4.5ghz or they have 4.7 not sure base speed are bit way a head ...

So before I would change it to AMD I would like make it sweat bit more

Thanks for help!

OC and Undervolting the 4080 Super Noctua

Hi!

I'm pretty new to this, but I've been trying to undervolt my 4080 Super Noctua card, while overclocking the VRAM (+1300 in the Afterburner).

I get stable performance in Cyberpunk 2077 benchmarks while on 945-950mV, at 2775 GPU Clock. I've settled on 950 after some stability testing for now, but I've been noticing that after applying the new curve with MSI afterburner, and then checking performance in various games, the voltage sometimes jumps to 1015, although the limit for the curve is 950. How is that possible, and am I doing something wrong with the undervolting?

Otherwise, the performance with VRAM OC and the undervolting is actually better than stock, with reduction in coil whine.

Here are my specs:

CPU: AMD Ryzen 7 7800X3D 4.2GHz
CPU Cooler: Arctic Cooling Liquid Freezer III 240
GPU: Asus Noctua RTX 4080 SUPER
Memory: Kingston 32GB (2K) DDR5 6000MHz FURY Beast
MB: ASUS ROG Strix B650E-F
PSU: Seasonic Focus GX 850W ATX 3.0

In what situations and increments should you raise voltage in afterburner?

Trying to OC my 3060 12gb. I read about someone who claims to have managed to pull over somewhere around +280 core clock by increasing the voltage, but seem to be running into a total roadblock and can't get above +235 and maintain stability. I tried increasing my voltage little by little, but everything seemed to be getting less stable the higher i upped it (most i got was +15 before stopping).

How would i go about determining if my benchmarks are crashing due to not having enough voltage/from just having hit my limit on my core clock?

Very Sudden Temps Increase After 15min Of Prime95 Stress Testing

Hi guys,

I hope you can help me out with this.

I am trying to overclock my i9 9900KF on a Z390 motherboard and a 240mm Corsair AIO.

Currently I have the following settings in BIOS. Most are from the official Aorus Z390 motherboard guide (writing out of memory so I may be missing something):

LLC - Turbo
Vcore - 1.32v
C-states/enhanced multicore performance - disabled
VT-d - disabled
AVX offset - auto
XMP profile - enabled (with xmp: corsair vengeance pro 2x8gb ddr4 3600mhz 1.35v)
VCCIO/VCCSA - 1.2v on both
CPU base clock - 100MHz
CPU clock multiplier - 50x
Uncore/Ring ratio - 47x

If you need to know any other important setting just ask please.

The thing is that I am stress testing with Prime95 (latest version) on small FFT and AVX disabled since I don't plan on using AVX apps/games and want everyday stable OC, not rock solid, unrealistically stable OC.

And the issue I'm having is that while testing, after approximately 15min, while temps stay more or less on the low to high 70s, I get a very sudden increase in temps, reaching more than 90ºC for just a second, then the computer turns off, I imagine to protect the CPU since the actual temps must have reached the protection limit.

So, my question to all of this is, what is causing this? It's not like a BSOD kind of instability, instead, the temps just suddenly go very high, almost instantly, so what am I doing wrong? What should I change first? I've been trying to increase Vcore in order to fix this, but I don't want to keep increasing it if I can change something else from the list above or something you can think of, since I don't want high temps just because.

Additionally, what setting must I change to keep the 4.9-5GHz but bring down the Vcore?

I will edit the list of settings as I keep trying to get a stable OC, but if any of the suggestions here work, I will make a note on the bottom of this post to make sure whoever reads this knows what the solution could be.

Thank you in advance for your help.

UPDATE: Okay so I've been reading that Prime95 changes test modes during the stress test, and maybe that could explain the huge increase of more than 20ºC in temps, this is why I've gone back to 1.3v on Vcore, so that when that mode kicks in, the spike doesn't reach the protection temperature. I am currently stress testing as I write this. I will let it do its thing for 15min again and report back on how that worked out.

UPDATE2: Okay so I had the same problem at about 15min aswell but this time, Prime95 stated some log error, then some "3xxK self test passed!" and then it shut down, but I was busy reading all of these new messages so I couldn't see if temps were high when it happened. I have since raised mult to x50, uncore to x47, vcore to 1.32v, and llc to turbo. I know most of these except the vcore will increase instability but I can't think of anything else to do right now. I really wanna reach 5GHz if it's within 80ºC.

UPDATE3: OCCT also gave me issues at around 15min, but instead of shutting down, the computer just freezed. Since this, I have tried lower voltages like 1.25, 1.28v, but the computer freezes with Prime95, instead of shutting down. So apparently I'm within these two outcomes, from which I cannot escape at around 15min of stress testing: Voltage too high - temp spike and computer shuts down. Voltage too low - computer freezes. ¿IS THIS A SYMPTOM OF SOMETHING SPECIFIC? I have now disabled the DRAM xmp profile and set my VCCIO/VCCSA to 1.2v. Currently testing on Prime95 again.

UPDATE4: It froze again. This time I could read that "384K self test successful!" message correctly on Prime95. I Also noticed the freezing/shutdown always occurs when the test transitions from 44000 to 7000000 Lucas-Lehmer iterations on at least one worker. So I reenabled the xmp profile again, since it doesn't seem to be the issue, and set AVX offset to auto. Currently testing on Prime95 again, will report back but I feel like I need to increase Vcore again.

UPDATE5: Still same issue, freezing on the 7000000 Lucas-Lehmer iterations on at least one worker. Since I can't seem to find the issue and have been playing CPU intensive games without issue below 80ºC, I will try and use the computer with the current settings mentioned above. They seem to work fine for now. If I end up having BSODs or freezes with normal use I will report back. If you don't hear from me again, it means the above settings work for the first 15min of Prime95 and within an intensive gaming environment for an indefinite period of time.

Massive fps boost on cpu bound games with SVM turned off

when i was tinkering with my overclocks i noticed that SVM mode was enabled, so i disabled it and my fps on The Finals (i consider this game kinda cpu intensive) goes from around 150ish fps to 180-190 fps, but synthetic benchmark score such as cinebench and cpu z stays the same though. Does anyone have the same experience?

Newbie to overclocking, any suggestions to milk out performance at a high but stable level for my build?

To those that would be willing to help me out, I have a small request of "What would be the best settings for me overclocked" and "What are the drawbacks of it."

Long story put short, I've been having issues in certain games that are fairly unoptimized and sadly do not take advantage of the 3d cache on my 7950X3D, I'm looking to try and boost my performance, even by just a little bit. Below are the specs of my current build, as well as any current settings I have.

CPU: R9 7950X3D, Stock settings

GPU: Gigabyte Eagle OC RTX 4070 12GB (It is currently being auto overclocked by GeForce Experience, +80MHz on the GPU Tuning, +200MHz on the VRAM tuning.)

MOBO: ASUS TUF GAMING X670E-Plus WIFI

RAM: CORSAIR VENGEANCE 64GB (32x2) DDR5-6400 CL32

PSU: 800W Thermaltake (Unsure exactly which model it is)

CPU Cooler: CORSAIR H150i Elite LCD XT 360mm

I've attempted to run the auto overclocking on Ryzen Master before, but that only resulted in me having to pull the CMOS and doing a hard reset of the MOBO, lesson learned on that. I'm wondering if anyone has any ideas as for what would be some good settings for me. I'm able to run games like cyberpunk with no issue on max settings, pulling about 80FPS on overdrive settings with psycho raytrace and path tracing enabled, but that's only because of DLSS 3 being enabled. I'm sort of looking to get that extra oomph to be able to not have to rely on DLSS 3 to process the anti aliasing which makes it look somewhat ugly.

Fairly impressed I can get to 8600MT/s on a 4-dimm board in G2. Max I could do on my Z790 Carbon was 7600MT/s. Though Raptor Lake's latency is still much lower.

I messed up

I got myself a 9800x3d a few day ago with 48gb of cl36 ( not the best i know but good deal on it ).I tried a lot of AAA games and everyting was perfect, cpu is impressive. Then i was playing Avatar Frontiers of Pandora game was smoot pushing on ultra with frame gen with fsr.

I wanted to push more, went into Ryzen Master and push that slider to 6000 thinking it'd get my memory to 6000mhz like it should be on AMD. I also thougt it would just crash and go back to normal like it does with intel or when you do it in BIOS.

https://preview.redd.it/zh7ei9rji54e1.png?width=494&format=png&auto=webp&s=0ed09a943ac38b5e6893a9049109aeb6a9212cb8

Long story short, pc black screened after restart, wouldnt post i had to do a CMOS battery reset.

Now the pc takes a good 20s to boot with the RAM led ligthing up in red on the motherboard. It still gets to windows and the red led turns off. Pretty much all the other games function normally( some are weird but maybe i'm biased). But now i cant get Avatar to work correctly it stutters like crazy,

I tried to reset the BIOS settings; the Ryzen master settings. Still it boots slowly, Ram led is on and some games have a sketchy performance

Is there a way to fix this ? Like the pc somehow function normally but i know something is wrong. Did i

I know i'm dumb as fuck plz help

Best ram to boost gaming performance

I am looking for ram to pair with the 9800x3d in a x870e aorus elite mobo with a 5080 when it comes out. I have been trying to do research on the best ram for gaming performance but I am getting a lot of information that I myself am not able to really comprehend or understand right now. I am looking for ram to over clock for games such as R6, BO6, and other fps games. I would prefer a 2 stick kit so that I can have dual channel for the board. Thank you guys in advance

Built a new PC with an AMD Ryzen 5 7600 CPU, what are some good guides to get into overclocking?

Title. I've never overclocked a CPU before. Not too sure where to begin. My CPU is cooled by a thermalright assassin spirit 120 evo fan.

EDIT: Essentially trying to get better CPU performance in Lord of the Rings Online, which appears to bottleneck the CPU-load of the game onto CPU 2 (see image here)

Help with 4x32gb dimms vs 2x32gb

Hi friends

I have a question

I’ve got an aorus pro x x670e motherboard and a 7800x3d

https://www.gigabyte.com/Motherboard/X670E-AORUS-PRO-X motherboard

https://www.amd.com/en/products/processors/desktops/ryzen/7000-series/amd-ryzen-7-7800x3d.html

I am currently running 2x32gb g skill rgb neo white sticks

Check this out on @Newegg:G.SKILL Trident Z5 Neo Series 64GB (2 x 32GB) 288-Pin PC RAM DDR5 6000 (PC5 48000) Desktop Memory Model F5-6000J3036G32GX2-TZ5NRW https://www.newegg.com/g-skill-64gb-ddr5-6000/p/N82E16820374524?tpk=1

My question is this- is it possible to add two more sticks of this and go to 128gb? Will I still be able to run the expo profile with 6000mhz and tight timings?

Or will I be limited to a slower speed? And if that’s true, how much of a performance hit would it be compared to the gains of 128gb? Should I just stay at 64gb in that case?

My primary use case is playing DCS in VR

does CPU VDDP matter? (not CLDO VDDP)

Yes it does.

I'm running 4066mt/s ram in sync, UCLK & FCLK are 2033.

I started trying to bring the voltages down little by little, one by one and staying WHEA free.

CPU VDDP +0.100 is very critical for my setup, and this voltage almost never gets talked about.

I lowered it to +0.060, and immediately had crashes in Doom Eternal at 640x480 unlimited fps, which is very stressful for CPU and PCIE.

(CPU & Mem stress tests still ran okay, however)

I suspect this voltage has something to do with powering PCIe logic / some other IO on the SOC or on the IOD

Therefore, before pumping SOC voltages way over 1.2v, check this CPU VDDP first.

It didn't seem to affect the CPU temps that much.

For anyone interested, just in case, my Zentimings.

+200 pbo, bclk 100, vcore offset +0.030, LLC Low.

Does undervolting really improve gaming performance?

Hi all. I'm trying to understand the relevance of undervolting my 14900k to gaming performance.

I understand that with the 14900k, there are two main limiters to performance. The first is power limit and the second is thermal limit. Thermal limit is very straightforward, chip too hot? Throttle down. Power limit states that the product of voltage and current must not pass a certain threshold, and if it passes this threshold, the clocks go down. Since voltage and clocks are bound together, if one could achieve higher clocks at lower voltages, the performance would improve in power-limited scenarios.

With the new microcode, provided that one has a reasonable AIO cooler, power limit is much more likely to trigger than thermal limit when running a benchmark or a stress test, with Cinebench R23 being the gold standard. So to gauge whether a BIOS tweak helped improve the performance, people would run R23 and check the score. Users would often start with 37k-38k BIOS score (on 14900k), then undervolt and improve to 39k-41k. So on paper we're talking 5%-10% improvement by undervolting.

The thing is power-hungry software like R23 and P95 render the CPU power limited (253W) throughout the entire run. Meanwhile, CPU-heavy games will not come close to the power limit of the CPU - even spikes are rare. Therefore it seems that the score improvement in power-limited cases is irrelevant to gaming. In gaming scenarios, there is probably even "voltage to spare" to push for higher clock speeds. I could imagine a case where a CPU overclock would yield better performance for gaming while achieve lower score at R23.

Because of this inherent conflict, what is the proper approach for maximizing CPU performance in gaming? Also, how does one test "real-world", i.e. not power/thermal limited stability of a CPU overclock?

Apperciate your feedback

New to overclocking. Ryzen 7 5700x pbo setting and low r23 score

Hello everyone Let me preface this by saying that I'm a complete noob when it comes to overclocking so I just followed some YouTube tutorials and played with some pbo settings in BIOS and I got this result in cinebench

As for the pbo settings I changed the following

PBO advanced Limits motherboard Multiplier 10x Boost 200 CO -25 all cores

How can I interpret these results and is there a way to improve the multi core score?

I've seen scores around 15500 to 16000 on this forum for this cpu

Thank you all for any input

i9 12900k vs i9 12900ks

Am currently looking to upgrade my current CPU, an i5 12400f due to it bottlenecking my GPU an RX 7800xt in some cases and needing more power for productivity work which consists of Solidworks with FEA and flow simulations. Have been avoiding the upgrade due to 13th and 14th gen problems however stumbled upon this great deal on an i9 12900ks for 269£ or the i9 12900kf for 249£. I am on a high end b series board and have a good enough psu to keep up with the i9 12900ks. Now i am just wondering is the KS worth it, specifically for high speed memory overclocking (samsung b die)? Is this way to overkill of a cpu for my setup? and finally is my 240mm aio in a small Matx case good enough, will be undervolting.

9800X3D CPU VDDIO Voltage?

What is the normal range for CPU VDDIO voltage? I am trying to OC up to 6400 mem/2133 IF and I just can't get past 6000. I have been comparing my numbers to others and I noticed it appears my CPU VDDIO may be lower then most.

Here is my current EXPO then tuned DDR5 6000 setup.
