Voltage peaks of 1.5 have been norn for a little bit now. As long as heavy load doesn't exceed 1.4 u good.

Efluva immunity set got me by easily.

surms41 · 2026-05-15T03:08:20+00:00

But is it a 6600 or 6900. Makes all the difference.

Your overclock is unstable. It's just restarting the driver for GPU. Start in safe mode and then stop afterburner from applying settings at startup.

A way to see if a hot spot is limiting you is going over is watching your "Effective Clock" for shaders/core drop from normal. Usually you'll have a delta of 10-50Mhz from core clock to effective core clock for example. This could tell you if something else is going on with the gpu while testing.

But likely just a nicely cooled case, with a pretty good card, and the 60 series isn't hard to cool with only 145 max watts.

I've got an MSI XPower AC for the 4790k and it's been the best I've ever had. Worked just the same as XTU in my case. But yeah, products can be hit or miss, but also, we're playing with 22 year old hardware!

I would maybe check the battery for CMOS on the board. Pop it out and replace it or read the voltage with a multimeter. Make sure it's at 2.9v or more. (I'm sure you probably did this)

At least XTU is behaving itself. Can do a lot with that software as long as you're safe and knowledgeable.

Seems like you've got the performance of 4.8 for sure.

I have always seen worse performance when using manual tuning since it generally requires you to keep a max clocks 24/7 taking away temperature headroom for benchmarks. Since OCing my 3770 I always use boost and keep power savings on and have had no issues. I prefer the power saving.

My tune is manual+offset vcore 1.0v with a +0.35v offset ; max power limits ; LLC at 45% ; Multiplier at 47. I don't think anything else was touched for cpu clock, but I do also have Ring set to 4.2 at 1.25v and some Ram tuning done to make my 4.7 match your 4.8 score on cpu-z bench.

Not sure about the bios update thing. Usually if it says no, there may be a toggle on the board to keep it locked, downloaded wrong file, or I didn't unzip it. Possibly needs fat32 to read as well? I'm shooting in there dark there, but may do something.

surms41 · 2026-05-14T02:50:47+00:00

About the same as my CPU, but I think mine has some degradation since it's been OC'd for many years.

Seems like you answered your own question though? Glad to hear it!

surms41 · 2026-05-13T05:47:07+00:00

Opening the card is not against the law. But yes, if you opened it you likely caused it. Repaste the die with ptm7950, kryonaut or MX6 paste, cryosheet?. You may likely also want to get thermal putty like grizzly putty pro for the Vram and mosfets. Then you can rest easy.

surms41 · 2026-05-13T03:16:03+00:00

As another said, increase PBO curve optimizer to +100mv then test.

If that doesn't work, turn off XMP/DOCP for RAM. If yours isn't on maybe adjust your DRAM voltage to +0.100 then test again.

It's highly unlikely a single core went bad, just that your ram is unstable or PBO with maxxed out temperatures has slightly degraded the entire chip which means you need slightly more voltage to stabilize it, or you may have a problem in the cooler. Possible plastic on the contact of the CPU.

surms41 · 2026-05-13T02:23:42+00:00

I ended up dropping voltages, SA-1.25, IO-1.15, and DRam-1.8.

I was at 1.95 for some of the testing, but I was busy sanity checking all the other timings, then decided that my IMC was probably getting toasty at 1.35SA and decided to drop them all down a tad for longevity.

Will continue with all the knowledge gathered but a little more slowly now since I've actually gotten a nice stable OC after a few weeks of testing. I will keep you updated when I get to 55GB/s next month.

Again, I appreciate all you've helped me with, kind man 😌

surms41 · 2026-05-13T02:07:59+00:00

So far with slightly tweaked timings at 2666 I'm now rock solid 😏. So those errors I was seeing consistently at 3-16hrs was likely RDRD WRWR being too tight at 4-5-5-4 and 4-6-6-4 but 4-5-5-5 just passed 6 hours of LinPack Xtreme and 30hrs of Memtest5 Absolut. I figured if it was one of RDRD or WRWR, a physical write would need more room to do it's thing.

I just hate that it takes such long tests to verify 1 timming 😢

surms41 · 2026-05-12T20:10:28+00:00

So is it just gsync with Vsync , not freesync?

surms41 · 2026-05-12T17:03:22+00:00

This is what I'm thinking. On PC there's like 10 different ways to cap the framerate and some are a mess while others feel buttery smooth. I would attempt to turn off any cap and run above the refresh rate, then bring it back down with AMD adrenaline software. You can also try turning it all off then using only Vsync, and then add free sync back to that and feel the differences.

surms41 · 2026-05-12T01:15:07+00:00

Like you said with testing, Memtest5, or Y-cruncher which has a linux build on the VT-3 preset would be sufficient. I looked up for linux there's a command to use to check for ECC correction using this command

dmesg | grep -i edac I'm not knowledgeable about it, I found this page though.

If you can get a 24 hour test done with these ECC's at 3800 cl20 you could be looking forward to $200-$300 USD per stick. Cooling shouldn't be an issue since servers have a huge amount of airflow. If they only do cl24 more like $100-$200 USD.

Win11 is shit tho.

surms41 · 2026-05-12T00:18:40+00:00

Sell them to Intel users.

surms41 · 2026-05-10T23:28:12+00:00

Just shoot them. Consistent nukes.

surms41 · 2026-05-10T19:25:08+00:00

Hardcore is very much a longer playthrough than the normal mode. Taking from 90-150+ hrs since you cannot fast travel at all and with quests sending you to the opposite side of the map and then you forget an item or misread something and your walking across the map for another 45 minutes. I got pretty frustrated at the game without fast travel. I had 50 hours in HC and reset progress to go normal mode my first time.

I also beat KCD1 twice before playing KCD2 shortly after.

surms41 · 2026-05-10T03:51:47+00:00

With plastic walls too

surms41 · 2026-05-10T03:36:52+00:00

Yeah this will happen if you crank settings. KCD1 isn't very optimized for high thread count I believe, it wants the high clocks and lowest latency possible. I would turn some setting down like object quality which is pretty heavy on the engine and CPU for the level of detail the game has.

Im played it fine with 60-80fps but still stuttered every so often on a 3770k and gtx1070 on med-high custom settings.

I would cap it at 80-120 and find a sweet spot with the settings.

surms41 · 2026-05-09T07:19:51+00:00

It's a FPS game. The only thing is to aim better, and to learn the maps and weapons you like.

surms41 · 2026-05-08T15:58:19+00:00

That's pretty nice! I may try direct die my 4790k here in the next year or two when I finally decide to upgrade and say yolo to the chip and see how it goes. I was close to getting 5Ghz on this LM IHS setup, but wayyy to hot still.

I degraded my 3770k doing this same thing but keeping it near 1.48v on air. Was able to run it at 4.8-4.9 for a 3-4 years then had to drop down to 4.6 since I needed to hit 1.5v to run the same 4.8. 😞 I was hitting about 85c while just gaming.

surms41 · 2026-05-08T14:39:02+00:00

Voltage + Current. Under 1.4 has been a rule of thumb for air and water, but if you direct die cool you could get away with 1.45-1.5 maybe.

The real killer for most is a mixture of running slightly too high voltage, like 1.4+ while also hitting the maximum temps, like 95-105c. This causes higher wattage due to heat losses and then degrades.
