Nach einer intensiven Overclocking-Reise mit meinem neuen RTX 5090 und 9800X3D-System freue ich mich, die endgültigen 3DMark-Ergebnisse zu teilen, die mit einem Matrix-BIOS und Luftkühlung erzielt wurden. Das herausragende Ergebnis war im Time Spy Extreme, bei dem ein Wert von 21.126 einen beeindruckenden 4. Platz weltweit sicherte. Weitere starke Ergebnisse sind ein Time Spy-Wert von 41.645 (84. Platz), ein Port Royal-Wert von 43.890 (79. Platz) und eine Fire Strike Ultra-Rangliste von 65. Mein Steel Nomad-Lauf ergab einen Wert von 17.377, was knapp außerhalb der Top 100 lag – ein fast gelungener Versuch, aber dennoch eine solide Leistung.
Dieser gesamte Prozess, von der Zusammenstellung meines ersten ernsthaften PC-Baus bis zu diesen Ranglistenpositionen, war eine wertvolle Lernerfahrung. Meinen herzlichen Dank richte ich an das xOCD-Overclocking-Team und die unterstützende Reddit-Community für ihre Motivation während des Weges. Für alle, die Interesse an Overclocking haben, empfehle ich, es auszuprobieren. Jetzt ist es endlich an der Zeit, zurückzutreten und einige Spiele zu genießen.
Will you keep that BIOS permanently, or was it just for overclocking?
The card undervolts well. Since some games aren’t optimized to fully utilize the GPU, you have the option to boost it if needed. I have spare connectors and a soldering iron on hand, just in case.
Update: An undervolt to 650W seems to be the sweet spot.
I’m really hesitant to try this. I’m not sure I trust that 650W power supply to be reliable.
I’m considering soldering on an additional connector to run the card at a continuous 800 watts, or even higher with a shunt mod.
Honestly, 650 watts is a great spot. If you have an ATX 3.1 cable with the H++ standard, it’s rated for 675 watts. Add the 15 watts from the PCIe connector, and you’re theoretically within safe limits.
I have an NZXT C1200 PSU, so in theory I could handle it. Do you know how much power it draws while gaming, not benchmarking? Does it still exceed 600 watts under a normal load?
Similar to my results with an MSI MPG 1250W, though it depends on your settings.
You can easily lock the power limit to replicate the old BIOS values, or apply a good undervolt around 600-650W to gain those extra frames.
I find that undervolting to around 1035mV typically keeps power draw below 700W.
I’m running my RTX 5090 Gigabyte Gaming OC at 895mV with a 2832 MHz core clock and a +2000 memory offset, which scores 15379 in Steel Nomad. I typically prioritize the lowest power draw and temperatures without sacrificing much performance. Your results are quite interesting.
Check my earlier posts—I achieved 16.5k in Steel Nomad using the Gigabyte 600W BIOS. A lot of it comes down to learning how to create effective curves.
I’ve reviewed your posts, but I’m unclear on your starting voltage and frequency. I’ll try to replicate your curve to compare power draw and temperatures in games. My card seems to have good silicon, as my current undervolt is quite aggressive and remains stable.
Start by applying your maximum stable overclock. For example, if +300 on the core is stable, set the memory to +3000 and the voltage to +100%, then apply. Next, raise the 0-925mV range together so that the 925mV point reaches approximately 2920-3007MHz. Higher is generally better, though you may need to lower it slightly for stability. Apply the change.
You will likely see a dip in the voltage-frequency curve. Smooth out this dip by repeatedly applying adjustments until the curve is fully flattened.
Now, raise all nodes from 925mV to 1000mV by about one-fifth of a grid square and apply. Then, pull down the curve between 1000mV and 1150mV and apply again.
For further refinement, you can raise the 820mV to 910mV range once more at the end, then smooth out the entire curve again as you did before.
That is the general method, but your specific values will fall within these ranges.
Impressive results for air cooling.
Did you use a custom BIOS? What are your GPU overclock settings?
This is just the Matrix BIOS with a custom fan curve, similar to the one I posted about a week ago.
The Matrix BIOS has been a game-changer for non-ASUS cards. With my Astral, I can achieve a maximum score of 16K in Steel Nomad. Good job.
Thanks, I appreciate it. Before using the Matrix BIOS, my best score was around 16,550. I haven’t been able to find that same exceptional sweet spot with it like I did with the Gigachad BIOS.
Did your temperatures change when you raised the power limit to 800W? I would be careful running at full power, as the Matrix does not draw all its power from the 12VHPWR cable.
The performance gain wasn’t as significant as I expected, but I am using an upgraded, non-stock air cooler. My memory clocks remain unchanged, though the core temperature does reach the mid-80s.
I know people running 2000-watt shunts without issue, so I’m not particularly concerned about a 60-second benchmark at 800 watts. I also have the resources and spare parts to handle any repairs if needed.
