basically the title.

Did some basic overclocks to multiple different parts of top of completely changing my fan curves.

Basically, I'm just waiting on stability tests atp. on the bright sidetemps are better under load so far.

Just finished tuning my new Ryzen 5 7500F on a Gigabyte B650 Eagle AX with an Arctic Freezer 36 and an RTX 3080 FE. I was hyped to dial in PBO after reading everyone's "-30 all core" success stories.

Turns out, I lost the silicon lottery harder than anyone else. Here is how my tuning went:

• +200 MHz / -15 CO: Infinite boot loops and "Automatic Repair" screens.

• +100 MHz / -10 CO: Chip choked on the Windows startup noise and instantly BSOD'd.

• +100 MHz / 0 CO (Stock Voltage): Made it to the desktop, opened Discord, instantly hard-crashed.

My chip literally cannot handle a single megahertz past its default 5.05 GHz factory limit, nor can it handle a single millivolt of undervolting.

I’ve accepted defeat, left the clock overrides at 0, and just set PBO to "Enabled" so the motherboard can at least handle the power limits.

Pour one out for my bottom-tier silicon. Anyone else have a 7000 series chip this incredibly voltage-hungry?

We’ve all seen benchmarks go brrrr after a driver update, but let’s be honest sometimes overclocking feels like changing random numbers and praying the PC doesn’t turn into a space heater.

What’s the most ridiculous overclock you’ve tried that somehow worked? And have you ever pushed things a little too far and instantly regretted it?

One thing I find interesting about overclocking is how an OC can look completely stable until you use a different workload. You can pass a benchmark, play games for hours, and think you've nailed your settings, only to get a random error when running something you didn't expect to be demanding. Different workloads seem to expose different weaknesses, whether it's memory instability, transient power behavior, or temperatures that gradually creep up. For the more experienced overclockers here, what's a stability test or real-world scenario that has caught you off guard even after an OC passed your usual testing routine? I'd be interested in hearing what failed and what ultimately helped you identify the problem.

Welp the new driver fixed whatever was making speedway scores lower🤷🏻

However, you now need the latest mvolt in order to bios override voltages and basically every other setting since Nvidia keeps trying to nerf mvolt.

You may have noticed only speedway sees score improvements while every other benchmark has the same top scores.

I believe this is because the new driver has messed up mvolt enforced input current limit behaviour as I'm not seeing my supposedly increased 12vhpwr ampage go up near as much as it did in the previous driver for power hungry benchmarks.

Please let me know if you get the same behaviour or I'm just having a skill issue lol.

Benchmarks like steel Nomad likes higher input current limits quite a lot, in fact the new driver gives me lower scores for Steel Nomad which supports my claim.

My fun goal is now to hit over 120fps or even better yet beat the top 1 4090. I see Alphacool has a water cooler compatible with 5080 Windforce sff pcb, will have to plan out exactly how I'm gonna go about water cooling this card as I think that's the only way going forward with this. Will watercool sometime in the next coming months.

so i spent the last week tuning instead of actually playing games, as one does.

steel nomad stock: 13,952
steel nomad after mVolt+: 16,969

that’s +21.6% on a card that already costs more than my first car. avg clock went from 2857 to 3030 mhz. my GPU is now basically a space heater with RGB.

the card: gigabyte aorus rtx 5090 xtreme waterforce (360mm aio). i paid extra for the aio so it can run cooler, then immediately used that headroom to make it run hotter

what i’m running:

• power limit 110% (the connector is fine. the connector is fine. the connector is fine.)
• memory +3999. not +4000. +4000 crashes instantly like it has a personal problem with that number
• xbar +450, sys +650 with +50mV. sys actually does something, xbar is mostly vibes
• custom v/f curve: around +300 where the card actually lives (~1000mV), and the top capped so it stops trying to hit 3200+ and dying in loading screens
• temps under load: gpu ~65°C, memory ~80°C

things i learned the hard way:

• the 5090 is always power limited in heavy stuff, so the trick isn’t more voltage, it’s more mhz at the same voltage. stock it sits at 1070mV doing 2930mhz, now ~1020mV doing ~3050
• every single crash i had was the top of the curve when the game goes from loading screen → full load. witcher 3 crashed so many times it should get a dev credit
• colder card = more mhz. my fans now sound like a jet taking off but hey, free performance

mVolt+ is honestly ridiculous, per point v/f curve, xbar/sys, voltage demands, stuff afterburner doesn’t even know exists. dev deserves a medal: https://github.com/b00nz/mVolt

credit where it’s due: the crash-hunting method (watch clock + voltage graphs, see at what voltage it died, lower only those points) came from this post: https://www.reddit.com/r/overclocking/comments/1xbnhjx/mvolt_guide_the_max_safe_daily_overclocks_for_5090/. go read it, it’s way more useful than my rambling

if my house burns down i’ll post an update. probably.

your card is not my card, don’t copy numbers blindly etc etc

Hi guys! I've been wanting to overclock my i5-12600k and I was wondering if there are any safe overclock settings? I've seen people recommending to overclock the P-core and E-core seperately but I'm not sure how that works. There has also been mention about undervolting too but it'd only reduce the power usage and heat, correct?

What would be the safe value for this CPU?

My specs are MSI Z690-a pro wifi ddr4, 4x8GB 3200MHz DDR4, RX 9070 XT and I am using NZXT Kraken Z63 280mm

If i can do anything better plz

Im doing PBO +200 with a -20 curve optimizer currently, my ram sub timings are pretty tight, I also have a moderate GPU OC on msi afterburner.

i was just wondering which tests are the absolute best to verify 100% fps, frametimes, overall performance stability for my specific OCs and hardware.

9800x3d

Arctic Liquid Freezer III Pro 360mm

Gigabyte B850m Force

Patriot Viper Venom rated for 6400MHz cl32

RTX 3080

So, i noticed that setting a negative voltage offset in mvolt behaves in a very similar manner to amd PBO, where setting a negative curve optimizer makes the cpu clock higher. The same happened with mvolt+ nvidia gpus.

However, is it worth touching sys and xbar voltage offsets? Or better leave those at 0?

i have asus tuf 3080 oc
temps are good its just the hotspot that seems high
on 3dmark port royal and in rust under load temps are around 74c with hotspot at 99.5c
the maximum it has gotta is 67c and hotspot of 98c in rust at 360 watts with a slight over clock
should i replace the thermal past i do not want to replace the thermal pads and i looked up my I looked up my exact GPU model and I could open it without needing to replace any pads and I could just replace the thermal paste only but should I
My GPU has never been opened before it still has the sticker over the screw

I’m about to run a y-cruncher CPU + MCU 30+ iterations

I changed up my OCs for more stability and longevity.

I did Cinebench R23 multicore and got 23847 which was a higher score than I got on -20 curve optimizer.

Hi there

I know I am a bit late to the party, but I want to push my reference 7900 XTX a bit more than currently.

It is actually fine tuned at -50mV uv, default max core clock (usually around 3050Mhz) and VRAM is sitting at 2650Mhz being Samsung die, I can push it at 2800Mhz for benchmark, but not stable in memtest_vulkan

This reaches under water about 19100 points in superposition extreme 1080p, which isn't too bad

I was thinking of flashing a slightly higher power VBIOS (Liquid Devil, 339W PPT + 15%) but there is not many reference of this one online, mainly Aqua BIOS at 400W PPT, which might be a bit too much for the 2x8 pins power cable (cablemod 18AVG cable).

I know I would have to hardware flash it and I already have available too for this doing some EEPROM dev on the side, I am just curious of the effect of it on the reference card and if the USB C display port would be kept. (Liquid Devil is 3 DP + HDMI).

Would love to push this puppy up to 389W PPT

Any thoughts ? Thanks !

Adjusting the xbar and MSVDD voltages are kind of new we never used to do this before.

As someone who has fried chips in the past, I am a bit uneasy adding a lot of voltage, what are your daily drive Mvolt+ voltages and clocks?
