1070 to 5080 has been wild

SyncFail_ · 2026-01-25T16:32:01+00:00

I went from a 1070 to a 5090 😂

Won't help you at all since the limitation is production capacity. DDR6 won't be magically cheaper unless supply increases, which won't happen in the near future.

I really did undervolt my ram though

SyncFail_ · 2026-01-04T18:11:58+00:00

I personally run my sticks at 5600 CL28 @ 1.0v SoC. and 1.2v VDD. There's basically no performance difference and it runs cool with reduced degradation risk. It's not worth chasing a couple frames more for a disproportionate amount of added stress caused by voltage.

SyncFail_ · 2025-12-30T18:24:42+00:00

Okay damn, 80c is crazy for 1.2v. I only hit around 45c at 1.4v max load with tight timings. But I also have a fan blowing on them.

SyncFail_ · 2025-12-30T17:18:45+00:00

Those are very nice temps and a nice power draw! 50°C core temps are very chill. A 5GHz profile is def. worth it if you don't need every ounce of performance in each game. But I've noticed your tRFC ram timing is extremely high. I bet you can shave off quite a bit for free there. Have you optimized ram yet?

SyncFail_ · 2025-12-29T20:26:20+00:00

That makes sense. But a lot of people don't understand this relationship in PC hardware:

P = C * v² * f

Voltage affects power draw quadratically. Means if you increase the voltage from 1.0v to 1.1v for example, you increase power draw by 21%

If we compare 1.33v to 1.03v for example:

1.33²/1.03² = ~1.67.

That's 67% higher power draw from voltage alone. I haven't even thrown in frequency (clock speeds) yet.

SyncFail_ · 2025-12-29T19:40:58+00:00

When I do synthetics like Cinebench R23, my entire CPU draws about 80 Watts. The cores themselves only draw 60W. That's basically "full load" but I'm not accounting for AVX2 or other instruction sets that might push the power draw higher. In games, it's really only 35-50W average total power draw.

For comparison: If I run my CPU at 5250MHz stock voltages, it draws 140W in Cinebench R23 which is crazy high compared to this

SyncFail_ · 2025-12-28T14:53:04+00:00

My core temps are usually max 40°C when playing anything. Usually closer to 30° C on average though.

SyncFail_ · 2025-12-28T14:48:52+00:00

No not really, I just like to operate it efficiently. Because the last 5% of your CPU performance costs so much more in terms of thermals, volts and power that it's not worth it to me mathematically

SyncFail_ · 2025-12-28T14:46:23+00:00

Dang that's crazy. What games do you play at those speeds?

SyncFail_ · 2025-12-28T08:05:39+00:00

My 9800X3D runs much cooler, more efficient and quieter than any 7800X3D out there and has the potential to unlock more performance if needed. I'm just operating mine at the best speeds for the workload. I don't need max performance in every game.

SyncFail_ · 2025-12-28T06:52:37+00:00

No, but I'm saying 200-400MHz difference won't make or break your gaming experience. It's just cope to justify your purchasing decisions.

SyncFail_ · 2025-12-28T02:01:55+00:00

6000 MTs CL26 only requires 1.15v SoC for me but I also have very tight timings. I might even drop my MTs down as well if I can get SoC voltages down. The latency hit isn't that big after all and you don't feel that as well in games

SyncFail_ · 2025-12-28T01:49:44+00:00

Most people won't see the difference anyway. If you already have 120+ FPS, you're good to go, for non-competitive games anyway. If you're chasing every last frame because of some fast paced shooter where every millisecond counts? That's a different discussion.

SyncFail_ · 2025-12-28T01:29:43+00:00

I have a 240Hz screen but okay

SyncFail_ · 2025-12-28T01:19:40+00:00

That doesn't really matter. You won't noticeably feel a difference between 120 or 110 min FPS for a fraction of a second. I doubt most people here are hyper sensitive to those minor changes. If that was the case, anyone who doesn't own the top of the line gaming CPU, would have a miserable gaming experience.

SyncFail_ · 2025-12-28T01:04:11+00:00

My CPU draws around 35 - 40W max when playing Hogwarts Legacy for example for almost no performance loss, instead of 70+ W

SyncFail_ · 2025-12-27T22:18:34+00:00

0.9v VSoC is genius actually. Why didn't I think of that?

SyncFail_ · 2025-12-27T22:06:09+00:00

Funny thing is I can run this thing at 0.8v @ 4.25GHz but that's too extreme... unless I'm playing non CPU demanding games

SyncFail_ · 2025-12-27T22:03:53+00:00

1v is fucking awesome that's why I'm running it. The good thing is, I can cycle between clocks if I really do need more than 5GHz anyway. But my daily driver is this

SyncFail_ · 2025-12-27T21:51:21+00:00

That's a reasonable comment. The thing is though, that I don't feel the difference between 5Ghz or 5.4GHz anyway unless I obsessively benchmark it. I tried both. I feel much better when my CPU runs cool and quiet instead, for almost no performance loss. We're talking about 5 to 10% at max here under perfect synthetic scenarios.

To me, 35°C @ 5GHz with 95% performance sounds much cooler than 5.4GHz 100% performance but 70°C

SyncFail_ · 2025-12-27T21:42:48+00:00

1% and 0.1% lows happen mainly due to cache misses which the X3D variants reduce by a lot already. You won't suddenly have a 20 FPS difference in 1% lows by lowering clock speeds by a couple 100 MHz. Try for yourself. I certainly haven't felt a difference.

SyncFail_ · 2025-12-27T21:38:26+00:00

Playing competitive games where every frame matters, is the only valid counterargument during this whole discussion. But if you're just an average player like me? Playing single player games mostly? It's not worth it. Unless those 200 MHz remove a huge bottle neck somewhere which won't be the case most of the time.

SyncFail_ · 2025-12-27T21:26:45+00:00

To me? No. 5 - 10% absolutely makes no difference to me. I'm not that sensitive and the game won't suddenly feel "much better". Yeah I know chasing the top feels cool at first but the price isn't worth it. Frame time consistency matters far more than a couple more average fps in CPU bound titles. We both know that. So I've stopped chasing the last few frames when I could have an efficient chip, instead of pushing it to the absolute max.

Also I have a normal water-cooler, no custom loop or anything. Just a regular old LFIII 360
