Boost your system's performance with AMD Record Ram!
Boost your system's performance with AMD Record Ram!
Hey all, Many of you will not know me so allow me to introduce myself, I'm Lewis and I go by the username ObscureParadox over on HWBot, I just wanted to share something which I achieved today and am pretty proud of. Use the extremely budget ASRock B650M HDV/M.2 and AMD's new 8500G APU I was able to achieve a ram validation of 10800MHz which is at the time of writing is the highest ram validation ever achieved on an AMD platform and the 8th highest validation of any system type as can be seen here - https://hwbot.org/submission/5480169_obs...5397.1_mhz This was done on a kit of Corsair Dominator Titanium 7200MHz 24GB*2 with air cooling on everything, no extreme cooling yet. Next step is to validate above 11000MHz and it is very much in reach as I can get it to bios currently but unable to get into windows just yet. I hope you enjoy little achievements like this as much as I do
I'm trying to stop thinking about this, but it keeps me thinking about heading to Micro Center and grabbing that combo—likely 8600G instead of 8500G, but pretty close. Still, a good score! Maybe I'll surpass your result if I can resist the temptation to take one.
They're incredibly enjoyable, the board performs remarkably well with these chips, particularly considering its affordability compared to other B650 boards. 8600G felt similar in this case, likely running about 200MHz lower at the higher end, but it's still a great silicon opportunity. I appreciate the challenge! It's refreshing to see more people engaging with the AMD platform.
Are you reaching memory or storage limits? Cl54 points out that a B650m HDV is quite affordable for its price. In a couple of years these units could drop in value on the used side, handling high-end specs like the 7950X and DDR5 chips (likely even higher at this rate). That would make it a great opportunity if prices fall. I wish I had the funds now—buying one of those setups would let me test performance under extreme conditions, both hot and cold. Also, running some stress tests to see how they hold up over time would be helpful. Most people don’t do degradation testing anymore, which leads to unclear voltage limits, especially for VDIMM. I’m curious about your OC settings—especially vsoc and VDIMM. If you push them to 1.7V+ VDIMM and 1.5V+ vsoc, it might work, though I doubt the stability. I’d probably go for a higher voltage if it means more performance. My Samsung GDs don’t seem to handle extreme voltages well, but my Hynix CFRS units start showing issues above 2V. I’m stuck on x58 trying to squeeze out 3200DDR3 from an i7 930 in air with some gears, and it’s not going well. My 2Gbit Hynix seems to fail at 2.6V, but my 2Gbit ones last longer at 2.1V. I’m hoping for something lighter on the IMC, maybe a 1/2Gbit Hynix board or similar. Right now I have $3184, so I’m torn between a G1 Assassin and an Xeon W3680 with extra parts—coolers, RAM upgrades, maybe a multimeter and trim pots. I’m leaning toward the latter since I want to see how far these can go, aiming for 3600+ DDR3 or even 4000 if I get better chips or better boards. The C11 chip isn’t doing much either. If these push past 3600 DDR3, I might need to look for something with higher core voltage or better cooling options.
I first assumed the system was constrained by RAM limits, but after testing various APUs, I realized it’s more about IMC restrictions. The lower cas worked to get Windows running, offering better stability compared to CL60, so further investigation is needed to understand the cause. Main voltage points were around 1.48v VDDIO, 1.3v SOC, and 1.15v VDDP. RAM voltages hovered near 1.56v VDD, 1.52v VDDQ, and 1.8v VPP. Higher values tend to cause instability, while lower ones keep things steady—it’s a delicate balance at high frequencies.
Can the socket reach higher speeds or is it similar to Ryzen 7000? The APUs and CPUs have distinct IMCs, which makes me doubt the 1.3V vsoc max claim on the 8000G APU. It’s likely the voltage won’t increase further, even with a RAM speed boost. I’m thinking about testing it at higher frequencies to see if the board can handle it or if the RAM limits performance regardless of voltage. The Ryzen 9000 seems to share the same I/O die as the 7000, so sticking with 1.3V vsoc might be safe.
