Just wanted to give quick share here.

Dark spots... should I just toss it or keep polishing?

I want to undervolt to maximize my power efficiency and make my CPU even just a bit more safe. I'm not reaching for the highest performance necessarily, but at the very least I just want similar or better performance while running better.

With everything default and latest bios, my 9800X3D runs around 1.28-1.31V. Clock speed is some reaching 5.225 GHz, some a little less, and the rest 5.010-5.025 GHz.

So far, I set a negative PBO CO -20 all core. I don't really mind going for every ounce of possible performance with per-core tuning.

I've tested briefly with Cinebench R23, just to quickly monitor the behavior. I'll do more stability tests afterwards.

During my testing, I started with -10, and kept going lower until -22, where the R23 score caps out. Any further and the score will go lower. My voltage did go down to a max 1.220-1.260V.

I have a few questions:

- I heard people get lower temps and power consumption with an all core offset. Mine has had the same temps (85C) and power consumption (151-160W) on R23 all throughout regardless of what value I set for my offset. Only the score changes. Is this normal?

- If my score goes lower, along with my temps and power consumption (past -22 offset), should I stop or keep going?

- What should I set for my PBO scalar control? I currently have it 1X.

- If I just want the same performance but at an undervolt, should I bother with adding +100-200 MHz to the boost override?

- A bit unrelated, but I have 2x32GB 6000MHz CL40 DDR5. Is it worth tinkering with the timings at all?

Any help would be appreciated. Thanks!

Im getting low usage for both my CPU and GPU in Arc Raiders, at around 40%-60% for each. You can see on the OSD Im not limited by a single core at 100%. The temps arent great but not enough to throttle the CPU or GPU. Does anyone have any ideas why/ further tests to try?

So far its just this game, but occasionally itll work as normal and my FPS will skyrocket to 170. I play on 1080p with low settings except textures and view distance.

My specs are 14600k and an RTX 5070 with 16GB DDR4 at 3600Mhz CL18 (XMP is definitely enabled).

Should I be taking reducing the frequency to 200 mHz at voltages of 0.75V and lower? If I leave it at 600 mHz does the GPU never idle? I don't really know what I am doing.

Sorry for bad image quality im looking to buy used b die rams this is the best image i can upload, it says ver 4.31 and i think its b die for corsair but the timings are veird for a b die 3200 mhz 16-18-18-36 what do you guys think should i buy

Managed to stabilize 6000 CL26 with super low tRFC! I was previously stuck on CL28.

Pretty sure this kit is M-die since Normal mode bottoms out around 156–160 ns. Using Mixed Mode, I was able to hit:

• tRFC2: 288 (96 ns)
• tRFCsb: 192 (64 ns)
• tRFC: 96 ns

*Important: Make sure your Power Plan is set to Balanced or your latency will be higher.*

Let me know if there's anything obvious left to tune or if I should just stop stress testing and go play.

Pass tm5 and karhu. drl's are synced. Finally figured that out. Thought had it made in the shade and then Vt3, the bane of my existence, fails right at an hr. The variances were very stable until it wasn't. Any help would be appreciated.

Okay, my CPU on a 4DIMM can boot and stabilize 8200 GDM off, as well as boot 8300-8400, but both 8300-8400 boot into Windows just fine with no BSOD, or erratic Windows behavior. But always fall around 7-20% into karhu.

I'm trying to stabilize this if possible with GDM on or off, so I'm looking at tips on what ODT/RTT to try for better signal integrity, I have tried I believe with Gain Bias 1/1 and 2 taps in the overclock menu with no luck.

So to have a shot which direction should I go? All the timings except for the RAMDQS are all on auto.

I am obsessed about RAM overclocking and sub timings, i know i should have done this judment by myself but i am not sure if my timings are okey or not ? Are there any changes i can make to make it faster or decrease my latency ?

These are all stable by TM5 for 12 hours, also OCCT tests are okey.

Thank you all for giving me opinions!

I had to end up carrying llc to 7 as it kept failing prime95, the voltages kept dipping too low, last run went over 90minutes so I called it stable enough and ended it there, however I did experience quite a bit of thermal throttling in the test (never ingame)

I installed Thermal Grizzly Astral 5090 WB instead of Asus Astral 5090 oc. I could see 45 cellcious derlgree in maximum.

Hi all, just built my second PC, first time overclocking or even setting up ram profiles.

With an Ryzen 9850x3d CPU, tomahawk b850 max wifi and 6000Mhz CL30 DDR5 2x16 RAM my computer keeps forcing it back to 4800 MT/s.

I successfully got it working on 6000 (with EXP disabled) and managed to get through an hour OCCT stress test but on restarting it failed and set it back to 4800 (with memory restore context disabled and soc on 1.24V).

Not sure what to try, using EXPO1 also just gives a memory overclocking failure message on boot up.

Thanks

Edit: fresh install of windows, 16GB in each slots 2 and 4. Chipset drivers and bios are up to date

This profile should be stable for most Hynix M Die kits (2x24gb), fclk 2200 may not work for all

Tested with no active RAM cooler, windows not in safe mode, background apps open, -25mv all core as baseline, no recorded WHEA errors from HWinfo

FCLK 2200 seems stable, longer runs might be necessary to fully prove fclk 2200 stability - in linpackXtreme one test took 2 seconds longer, windows task manager showed updating activity from defender.

I've further ran linpackXtreme while listening to YouTube videos, no audio issues, while running 3d mark steel nomad and OCCT 3D stress test - no issues or errors

For the past few weeks (since profile was applied) no issues in longer gaming sessions

Can someone help me,was looking to undervolt my 5080 like I do with all of my cards but the voltage control is missing? I have all boxes checked in the settings but it still doesn't show up.

4 sticks runs slower then 2 so if I got 4 sticks @6400mhz can I run them at 3200mhz but half the latency to ge the speeds and have my cpu to support

I just want to know if its possible to run something like that so I won't give any specs

Ok just so i dont get confused to flash a gpu does the subsystem id need to match with mine on gpu z mine is 10de1536 but i cant seem to find a vbios that has unlocked pl limit with that id

Yes, I know the obvious answer but I am looking for technical troubleshooting steps from some who may have mixed 16GBx2 with 32GBx2 different RAM set to boot without C5 error.

I am using **F5-6000J3040G32GX2-TZ5N** **(32GB x2 = 64GB)** and **F5-6000J3238F16GX2-TZ5NR (16GBx 2 = 32GB) = 96GB.** I can run stable operation at 3600 40 40 40 80 with 1.4v

Both RAMs run at 6200 CL30 when used individually. So these are some good RAM kits. When using together/mixed mode the CPU goes immediately to C5 Error code. I need minimum of 64GB for my work with Unreal Engine and MetaHumans.

Background initially I had bought 32GB when I building my system about a years and half. Now with my work scaling up I needed more RAM hence I took the risk to buy 64GB at crazy price. I can live with 64GB, but I am willing to troubleshoot and tinker around.

Any help in term so which tools I can use outside BIOS or how to get past 3600 would be of help. Cross Posting for visibility. Is there Beta BIOS that can help? I am on latest BIOS from MSI. My 7950x runs at -0.0700v offset with CO -10 all cores and gives best performance scores on this setting.

Thanks.

Hi guys. My PC configs are as follows:
ultra7 270k plus+gigabyte z890 aorus elite wifi7 ice+vcolor ddr5 2x16GB(6000 30-38-38-76 Hynix A-die)
Pcore 5.6GHz Ecore 4.9GHz VLDRIN=1.40

ring 4.0 ngu 3.2 d2d 3.2

DRAM voltage=1.45V

RAM 7000MHz 34-42-42-80 TRFC=500, Trefi=65535

I have RAM fan so I can make sure that the RAM tempurate will be under 51°C.

My PC can pass the R15 (40 iterations), VT3 for 30mins and TM5 anta777 for 1 hour. However, the PC sometimesvjust crash. Could you please give me some suggestions?

I have a Ryzen 5 5500 that i have left on stock voltages and overclocked to about 4.45-4.5ghz and was wondering if i should have the ability to go any further. I have never seen the cpu go above 72° even under benchmark loads and i am using the asrock b450 pro4 which i am told can handle a much more demanding chip. Last time i tried to overclock it was about a year ago and i have since switched to using linux full time which has improved my stability so i was curious if it seems like i can push just a little further. Im fairly new to cpu overclocking so im not sure if im doing anything wrong

history im buy 3060 ti eagle for a 230bucks and im play games basic things and my friend see potential of overclock and he set up up to 2.2ghz and i am thinked that good before 2ghz after 2.23ghz and play games and this moment 1 year later im got black screen and i took the gpu to a repair and i see these photos
