7700k doesn't boost to 5ghz anymore?

I noticed today while doing some rendering that it runs slow for simple rendering. So this CPU I overclocked to 5ghz a few years ago and it ran just fine with temps under 80 Celsius. I have water cooling. But today I noticed in task manager that it doesn't boost over 4.2, I looked in bios and all of the settings are as set, nothing changed. I also cleared CMOS to see if something Changes, but no luck. Any ideas?

High Score! Look at Me Look at Me! LOL

With a big smirk and much sarcasm I announce my triumph over the other three people who bothered to run PCMark10 with a 9600x and a 7700 XT.

Can't change temp limit in MSI afterbuner (Zotac Gaming 5090 Solid OC)

As the title says I can't control every slider in Afterburner (4.6.6 Beta 5) except for the temp limit. For some reason, the slider is greyed and the chain is off.

rog strix b550 maximum temperatures

have a ryzen 5 3600 on a rog strix b550 - f gaming . i am not overclocked. i used ooct to check compatibility of parts or stability. i used hwinfo. my CPU temps reached sub 90 degrees C. so my motherboard cpu (weighted, tsio, package, etc... was around that temperature also. i know the CPU can max out at 95 degrees, but is this safe for the motherboard? this is a brand new build.

How to stress test gpu

Because i used occt and furmark, and even put 300+mhz on memory and 75 on core and for 4 hours each no errors at all, but every game crashes after few minutes (when i underclock -75 mem no crashes for hour+), clean reinstalled windows on new drive with new ram and psu, replaced the thermal paste on gpu and it doesnt exceed 70C

Rtx 2070 8+6pin 700w psu newest windows 11 drivers: every in last 3 years (studio drivers made the crashes after half an hour not few minutes

5800X3D PBO, curve optimizer and AMD CBS

Hello everyone!

So I have been making my research regarding enabling PBO, setting the curve optimizer and the best settings on AMD CBS.

As I am not an expert I wanted to kind of make a list of what I need to do so you guys can kind of “approve” and guide me.

  • Enable PBO on BIOS (should I use Enable or Advanced?);
  • Set PBO limits (PPT, TDC, EDC);
  • Curve Optimizer: Manual, Negative, -30 All cores
  • AMD CBS: CPPC = Enabled, CPPC Prefered = Disabled, Global C-State = enabled
  • Test?

Thanks a lot!

Best OC settings for 4090 Strix white

Tried my luck getting 50 series. No avail.

Got lucky with a used 4090 though.

What are the best settings for this card to overlock for actual gaming? I don’t care about benchmarks that much, except to make sure the card is performing healthy.

I’ve heard stuff about the voltage and unlocking it but can’t find a clear guide.

Thanks!

69C, 65535 REFI, stable?

Just curious what everyone’s thoughts are, I have a Corsair 32x2 kit with Hynix A die at 6000 using basically exactly buildzoids timings and voltages from his recent video on dual rank 32gb kits.

I ran ycruncher, and prime95 for hours and then decided to add furmark to it to cook the ram with my 3080, hwinfo64 says temp of one stick is 69C and the other 68C, and haven’t errored.

Everything I have read says 65535 REFI is temp dependent and should error above 60C.

My question is how tf am I not?

(Ignore the procodt they aren’t correctly reported)

refresh rate gsync and vsync - fps lag

i'm having a major problems in different games. the first game is world of warcraft, in raids my game seems to stutter every so often and i feel sluggish and it affects my gameplay immensly. i have gsync enabled and vsync enabled in nvcp and have my fps uncapped in the game and the problem still persists. I turned gsycn and vsync off and set a cap within the game and the problem is still there. another game is league of legends. if i uncap my frame rate the game stutters, it's like ms lag i teleport and stuff.

my question is in a game like world of warcraft where my fps fluctuates very often from 70 - 800 what is the correct way to setup my settings to ensure i have no latency/lag problems? when i use gsync and vsync is locks my fps to monitors refresh rate but i noticed sometimes in WoW it changes from 165fps to 157fps randomly.

this is my setup - https://imgur.com/a/gzvGRl4

BIOS update higher CPU core voltage/temps

So I updated my BIOS version after seeing the recent instability issues with 13/14th gen intel processors and since updating my cpu core voltage and temps are considerably higher while running the same programs I would before for the same amount of time.

Previous temps after 2-3 hours of gaming would be around 40-60c CPU and package at 60-70c, core voltage would usually be 1.359v

Now after the BIOS update im running at 70c CPU temps and voltage is 1.474

Same games, same amount of time playing, same bios/tuning settings as before

Specs Processor 13th Gen Intel(R) Core(TM) i5-13600K, 3500 Mhz, 14 Core

Motherboard ASUS PRIME Z690-P WIFI D4

BIOS was version 2014 (2022) and updated to 3601 (2024)

Any ideas? Are these still safe voltages/running temps for long periods (up to 8+ hours sometimes)?

Thanks

6800C28 Finally Achieved

Oh ye :), lower latency than Arrow Lake AND matching/beating CPU-Z SINGLETHREAD scores with 245K's.

It took months of constant everyday retrain instability but I tamed the poor-bin A-Dies.

13700K - 230W 8 Thread Monster

57x all core locked/static, hyperthreading off (HT frequency limit is 55x and runs too hot).

50x ring locked/static (also only possible with HT off) (the lower latency is worth it)

1.8VDD, for C28 of course, 1.4VDDQ, 1.45 IVR/VDDQ TX, 1.45V IMC, 2V CPU Input Voltage.
1.15V SA

DDR5 96GB 2x48GB @ 8000mhz?

I have a Trident Z5 2x48GB CL32 6400MHZ Kit. Is it possible to hit 8000mhz with loose timings. I have a decent x870 motherboard? I've seen people hit 8000 with 6000mhz 48gb Z5 kits.

Need some advice on RAM timings/OC.

Hello again. I've been tuning pretty much everything in my system over the last few weeks, and I think it's finally time to tackle RAM. Or maybe it wouldn't be worth it in my case. What do you guys think?

I followed this guide for my 5800X and got everything stable using CoreCycler over 10hrs with no errors. My two fastest cores are at -9 and -13 with the rest between -27 and -30 with a +200mhz boost override. I am now getting up to 5.05ghz peak core speed with an average of around 4.75-4.95ghz.

I have also followed this guide for my Nitro+ 6750XT and get a stable max frequency of 2700mhz at 1.1v according to OCCT tests both on the 1hr 3D Standard and 1hr 3D Adaptive.

Now for the RAM. I'm running the DOCP profile for my G.Skill Trident Z Neo DDR4 3600MT/s with CL18 18-22-22-42. I'm running 4x8gb sticks for 32gb total. I have no idea where to start with RAM overclocking or adjusting timings. I did some searching and found that the exact same kit also comes with timings set to CL16 16-19-19-39, so I was considering leaving the RAM at 3600MT/s and just using those tighter timings. Should I do that, or would it be better to try to get faster MT/s at my stock DOCP timings? What is the process and testing software you'd use for the RAM? Would I see any meaningful performance benefit from messing with either the timings or the speed given my settings for the CPU and GPU? Any advice is appreciated!

Edit: Almost forgot to mention, this is running on a ROG Strix X570-E Gaming WIFI II motherboard.

AMD RX 7700 XT - stable without ray tracing but....

So I'm not expecting good performance with RT on but I tried to turn on RT I fortnite for a laugh, and it ran for a bit and crashed. Without it on I have played endless hours of gaming.

Settings at the moment are a significant under volt down to 925mv on the curve slider, and 2800mhz min and 4250mhz max (as I can't ever seen to get it over the 4k mark).

Wondering if I should up the voltage to keep it stable with tracing. I have the head room. My hot spot is 80 and the GPU temp is high 60 low 70 under 98% load gaming.

Thanks for the help in advance.

Is this Vdroop on my 13900k?

Recently had to update my bios to fix Intel's flub that was burning up chips. The ASUS board I use has default settings that make this thing run hot so I was dialing it back into performance mode and trying to do some load line calibration. I have it running about 15 degrees cooler now in general now which is nice and cool with one exception.

It sometimes gets these crazy spikes in temperature that seem to coincide with drops in voltage on Core VIDs (see image) and they are often enough to thermal throttle. It seems to happen semi regularly, but only enough to throttle once or twice throughout a night of gaming.

The rest of the time I sit closer to mid 50s->70s C. Idle at 30 C.

When an event occurs:

Voltage will drop as low as .7 V right around the time the temperature skyrockets to upper 90s.

I am pretty stupid about these things and should be spoken to as such because I'm still learning. Is this vdroop I'm experiencing and how do I correct it further?

(DDR4 question) If I go from 16x2 (b die 4000 15-16-15) to 16x4, how much should I expect to loosen my timings?

I still have many years before I will change my DDR4 mobo and I need to ramp up to 64gb soon.

I understand RAM timings need to loosen a lot if I go from 16x2 to 16x4.

How much looser should I be expecting?

Pc shutdown(event code 41, 6008) with light overclock. Mainbo or psu issue?

My spec: Ryzen 5 7600x B650m riptide wifi (support 12pin cpu) Kingston fury beast 5200c40(tuned to 5600c34) Andyson m5+ 650w (over 5 years old, only have 8pin cpu) Gigabyte 6700xt gaming oc 3fan Last year first release bios version let me oc to 5.45ghz 1.25vcore without a issue. Now with the same setting, i facing 100% shutdown in any avx benchmark(cpuz, occt). After reboot eventviewer always show code 6008. But if i increase vcore to 1.3v. Error 100% show kernel 41 which relate to psu issue. So what do you guy think? Is it a PSU or Mainbo issue? Maybe my Mainbo which 6pcb layer isnt good enough ? Or my PSU just cant handle 1.3v vcore?

XMP 6000 not running stable

Hello, I've tried to enable XMP 6000 on my mobo and it seems to be running hella sluggish and slow down my system, I used one of the 2 XMP profiles it offered me (5600/6000). Everything becomes jagged, from scrolling in my browser to alt tabbing out of a game. I'm not quite sure what causes that and I have to be honest I never overclocked something so I thought I might aswell ask here.

Mobo is ASRock B650 HDV/M2, Ryzen 5 7600, RX 6600, Patriot Viper Venom 32GB DDR5-600

5600 seems to run stable, although I'm still not completely sold on the performance. What should I do?

RAM Speed Not What It's Set to In BIOS?

Hey guys

I just did a fresh install of Windows 11 and upon downloading CPU-Z and HWiNFO I see that the RAM speed that I set in my bios which is 3,800 MHz is not what's showing up in CPU-Z and HWiNFO. I have my RAM speed in my bios set to 3,800 MHz but CPU-Z is saying that it's 1,064 MHz and HWiNFO is saying that it's 2,130 MHz. Does anyone know what's causing this and how to fix it so that my ram speed in my bios will be what my computer is? Here is a picture of my ram speed in bios and the reported speeds by CPU-Z and HWiNFO PIC

First time messing with RAM beyond XMP, any advice?

These sticks were originally 6000 CL28. I'm pretty sure Hynix-A
Frankly I don't know much about overclocking RAM, I had watched buildzoids hour long video explaining ram on Ryzen 9000's and he basically said to buy 6000 but trying to push it higher is worth it, with 6200 being reasonable and 6400 being harder to achieve. So I decided to try 6400 at 2133 FCLK first and found some timings/voltages posted online (I think it was someone saying they used timings from a buildzoid video) . It seems to work fine, I haven't noticed anything wrong and have been using it for about 4 days now.

Kinda just looking for advice from people more experienced. Can I be doing more? Is what I have now already good enough, or better than normal? I'm really not sure.
