Overclocking Ryzen 1800x reaches 3.9 GHz stable.
Overclocking Ryzen 1800x reaches 3.9 GHz stable.
Hello Everyone,
I've been experimenting with the new system and have been trying to reach 4GHz for the chip, which is the typical target for most of these processors. I'm trying to figure out if I've just had bad luck with the chip or if I need to adjust a few more settings, although it seems there aren't many options left now.
System Details:
- Ryzen 1800x
- GA-AX370 Gaming 7 (rev.10 BIOS)
- 32GB G.Skill Flare X 2400 CAS 16
- RX 480 8GB
- Samsung 950 Pro 512GB (OS drive)
- Corsair 750W PSU
- Windows 10 Pro
I've tested different settings in the BIOS advanced frequency, memory, and voltage menus. I began with the guide at https://overclocking.guide/gigabyte-ryze...ing-guide/ which got me into the system stable at 4GHz and allowed small FFTs for over an hour, but it crashed after a few minutes. I suspected a memory problem, so I ran MemTest86 overnight with no errors.
My current stable overclock settings are:
- CPU @ 3.9 GHz (100bclk x 39)
- RAM @ 2933 MHz (100bclk x 29.33 timings 20, 19, 19, 47)
- Vcore: Auto - stabilizes around 1.35V max at 1.38V in full tilt
- SOC: 1.3V
- RAM: 1.35V
- Vcore Loadline Calibration: Turbo
- XMP: disabled
I know that pushing RAM speeds up can improve performance with the Infinity Fabric, which connects two processors inside the Ryzen 8-core chip. So I chose slower timings and higher RAM speeds. The system felt much more responsive after the overclock, though further testing is needed to confirm.
If anyone has suggestions on my settings or ways to boost stability for reaching 4GHz, I would really appreciate it.
Hi Count Mike, just to clarify—are you asking about the automatic OC button on the motherboard? I believe manual clocking is the preferred method to achieve maximum OC while maintaining safe and stable voltages. I haven’t come across any information about using the automatic feature. All the available guides suggest sticking with manual clocking.
Well, initially, adjusting the VCore to Auto isn't something I suggest during overclocking. Manual voltage selection tends to yield a cooler CPU at the same performance and simplifies troubleshooting.
For Ryzen processors, maintaining a 1.35V VCore or lower is advisable for regular use. A maximum of 1.4V remains safe with adequate cooling, both for the CPU itself and its VRMs on the motherboard.
I would begin by setting the VCore to 1.35V, test it, and then slowly raise the value until you reach a stable voltage or the 1.4V limit. You might still be able to push further, but the chance of harming your CPU is higher.
If achieving a stable 4 GHz overclock with this approach proves difficult, revert to 1.35V and experiment with a higher BCLK and a lower multiplier to match the desired speed. Then, adjust the VCore again to check if more voltage improves performance. Keep in mind that a faster BCLK can also affect RAM speed, so a crash could stem from RAM issues.
If none of these steps succeed, altering the Loadline Calibration instead of setting it to Auto might be the better path.
Well, manual OC might work better but it also relies on various factors. Auto OC might not deliver every bit of performance but can offer a solid starting point from which you can enhance manually once you establish a base.
In my situation, with a 1700x, I can achieve only about 50Hz more with manual OC compared to what auto OC (TPU II) provides (while remaining stable), without needing to tweak the BIOS settings.
ZRace, I have already followed your instructions and manually entered all voltages. I managed to start and run blend tests in Prime no at 4 GHz with VCore 1.4v, SOC 1.3, CPU VDD18 2v, CPU VDDP +0.2v, load line calibration Turbo. This failed when I tested large FFTs and more RAM. I also ran tests using RAM with memtest 86 to verify my memory is healthy. It runs at a higher voltage than usual, which I don’t want to maintain continuously even though temperatures have stayed below the high 60s.
Running with auto on the VCore lets the voltage adjust so you’re not stuck at a constant higher level. I understand this isn’t always perfect for stability sometimes, but if it helps keep voltage spikes low and is stable, then it’s better? My VCore average is 1.348v max, 1.380v min, 0.936v.
I’ve set the SOC voltage manually to overclock my RAM as with auto it stays around 0.9v. I’ve thought about tweaking BCLK but wasn’t sure how it would impact PCIe components or whether it’s safe for my HDD or graphics card.
I haven't found a setting in the GA-AX370 bios to adjust for the PCIe interface using an M.2 950 pro SSD. I've kept the BCLK at 100 and concentrated on the multiplier. The RAM remains independent of the CPU through the same BCLK with a different multiplier, which should work fine.
However, reducing the RAM multiplier will also decrease performance, and since Ryzen benefits greatly from faster RAM, it's not worth the effort. Your BCLK is adjustable, but on my Asusit it doesn't change and consistently shows 98.7 to 98.8, which negatively affects both RAM and CPU speeds by that amount.
Agreed - thats why I've opted for standard BCLK and higher RAM multiplier to overclock the RAM. I've got my GSkill Flare X 2400 MHz running at 2933 MHz (29.33 x 100) with slacker timings. I read that its better to go for faster speeds with slacker timings as that improves the speed of Infinity fabric. There is obviously a tipping point with the timings though, if you slacken them too much performance will reduce in certain bench-marks.
