AMD FX6300 and Asus970 performance limitations
AMD FX6300 and Asus970 performance limitations
My initial recommendation would be to reduce the overclocking efforts. Avoid relying on an overclock when the root cause of your performance problems isn't clear. The rise in heat and power consumption far exceeds the performance gains from overclocking, which might lead to throttling. This could point directly to the issue. I wouldn’t rely on that PSU. The information I found a few years ago suggests it may not be a reliable unit—though it claims to be 750W, it likely doesn’t deliver close to that power on the 12V rail and probably isn’t of good quality in terms of clean power delivery. If you have a photo of the power specifications label, it would be helpful.
Force Manufacturing Ltd is a simple brand of ram. The 1333MHz model is clearly labeled. Given its budget-friendly nature, it probably won't perform well at 1600, but should work fine at 1333. A good replacement would be swapping out the Tacens unit—it's a 750w unit that covers all rails and adds extra power. The internal capacity is closer to 350w, making it suitable for most PCs. A decent alternative in the 450w-550w range would be the Seasonic S12-II or M12-II 520w. Though it has an older design, it fits your existing gear perfectly while staying affordable.
You mentioned it clearly... Over the past year or two, I've been experimenting with different systems, trying out various Manufacturers and Models of AM3/AM3+ Motherboards (ASUS, Gigabyte) and CPUs, along with DDR3 RAM from G.Skill, Corsair, Patriot, OCZ and Kingston. This was both for fun and to gain some knowledge! I’m certain that, no matter what chips are inside those heat spreaders, the support parts and build quality of the DRAM will influence performance. OCZ and G.Skill usually run their DDR3 at 1.65V for the best speeds, which often leads to more heat in the CPU and VRMs, usually causing throttling. I’ve managed to get some of these DDR3 pairs to operate at peak clocks with voltages nearer to 1.55V, but it’s still quite high. Corsair, Patriot and Kingston can run their highest XMP speeds without problems at 1.50V and are often easily overclocked at the same voltage. I’ve also noticed that when the timings and voltages for DDR3 become unstable, the system doesn’t always just stop working. I’ve experienced: 1) Posting in BIOS; 2) Booting into Windows and crashing at the 'Start' screen; 3) Booting into Windows normally but rebooting under stress; 4) Booting into Windows and throttling when under load; 5) Booting into Windows and experiencing CRASHING SLOW and WEIRD behavior (RETRY, DELAY, DELAY, DELAY). You seem to have a solid grasp of this field, so mixing and matching RAM might be straightforward for you. However, since the thread’s main focus appears to be at an early stage in system tuning, we should revisit the fundamentals! Have you checked if the issue shows up in ASRock’s Memory QVL? Moreover, this doesn’t rule out that the DDR3 RAM itself could be faulty, or the motherboard, or even the power supply. Manufacturing quality can vary greatly—just because a component is labeled 'EVGA' doesn’t guarantee it’s made well by all manufacturers, some of whom are quite critical about their build and selection. And finally... please get a quality new PSU! (and read what others shared about their experiences with the PSU...) Question - Issues with Sapphire 5700 xt nitro+ special edition, changed again for RX580 and still facing the same problems Hello everyone, I hope everything is okay. Before anything else, I’m going to post my rig details here: PSU: cooler master 600w Motherboard: b450 tomahank msi CPU: Ryzen 5 2600 RAM: 16gb Corsair 2800mhz SSD 1tb GPU: 1º rx 580 armour OC 8GB MSI, after Sapphire rx5700 xt nitro+ forums. Regarding the motherboard... it seems to be a UFEI BIOS. ASRock > 970M Pro3 Supports AM3+ / AM3 processors; solid capacitor design; Dual Channel DDR3 2400+(OC); 2 PCIe 2.0 x16, 1 PCIe 2.0 x1, 1 PCI; 7.1 CH HD Audio (Realtek ALC892 Audio Codec), ELNA Audio Caps; 6 SATA3; 4 USB 3.1 Gen1 (2 Front, 2 Rear), 10 USB 2.0 (4 Front, 6 Rear); 1 TPM Header, 1 IR... www.asrock.com I stand by my original opinion—swap in the standard RAM and reset everything to factory settings for a clean baseline...
It mainly depends on the amount of RAM available. Gskill snipers in DDR3 experienced low voltage issues at 1.35v, while newer models ran at 1.5v or higher, similar to older DDR3 designs when they were introduced. This difference is not related to RAM performance and shouldn't impact AMD CPU performance since the CPU sockets and chipsets are separate from the memory controller. Later Intel processors, especially after switching from Northbridge to PCIe hub and relocating the memory controller to the CPU, saw RAM voltages influencing CPU temperatures. This could affect VRM performance, particularly on older AM3 designs where voltage changes in Vcore and VID have the biggest impact.
Many producers switched to the 'LV' series around the end of DDR3 support. However, because the poster didn't provide the exact model numbers or DDR3 voltages in their specifications, we're operating without clear guidance. If they combined LV RAM, such as the G.Skill RipJaws X F3-1600C9S-8GXLL with older models running 4th tier at 1.65V or lower, issues could arise—certain modules may not perform well under higher voltages, particularly those that are 'chip only' and lack adequate cooling. We lack sufficient details, and it seems the poster doesn’t have the expertise to properly align these components for optimal operation.
Hello everyone! Thanks for your support! The problem turned out to be VRM zone overheating. Even with the fan directed straight at it, airflow wasn't enough. It was fixed by placing a 100mm fan near the VRM capacitors and slightly reducing the speed. Now the system runs smoothly under load and operates quickly. Still, my friend keeps facing the same issue—his VRM remains hot.
Hello! The system is operating smoothly at 1333 Mhz with settings 8-8-8-23 and a voltage of 1.5V.
You're correct, I'm still getting the hang of it.
Before syncing, I tried to configure the basic green RAM (the one without a name) for the specified XMP profiles in Aida64. It worked at 1.6V and 1.75V with clock speeds up to 1.75V, but I couldn't exceed 1400Mhz. The issue was related to overclocking the BCLK, and the system became unstable.
Thanks! I’ll make sure. I already placed an order for two 8GB DDR3 sticks at 1866Mhz two weeks ago. The RAM from my old PC is still the same brand, but it only has a "750W" sticker. I’m looking for a suitable PSU, but I’m tight on budget—can you suggest ways to evaluate a good PSU without just checking voltage and current?
