Increasing RAM voltage settings
Increasing RAM voltage settings
Aim for performance close to double the base speed as much as possible. A 2v overclock generally outperforms a 1.85v one because it offers tighter timing or higher frequency. Based on the Xtremesystems DDR3 IC thread, it seems likely a Samsung 4-bit revision B or D9QBJ might be the best fit, though certainty isn't complete.
Oh ok. Its not like every system, every ram, every IMC is the same (this is the second time I am saying this to you). I highly suggest you to stop making these type of "recommendations", as your testing is not methodical and only includes one particular cpu and RAM setup from 12 years ago.
It seems the components aren't very reliable. Apparently x58 imc starts to fail above 1.35v, but I'm running at 1.55v and it only degrades a bit over a few days. The 2v RAM is safe, though there are 2v spec kits available but I can't locate them. It looks like a 2000-2400 6-6-6 kit on Elpida Hypers might be the closest option. The manufacturer recommends 2.4v for DDR2, 1.6v for DDR4, and 2v for DDR3. I'm okay pushing DDR2 up to 2.9v just in case, but my team's current specs cap it at 2.34v due to time constraints. I'm considering a lower voltage like 6-9-5-10 DDR3 at 2v, or maybe 2.4v if I find a better IC. The big issue is the voltage gap between the IMC and the specs—it's a major concern. The DRAM should handle higher voltages, but the memory itself is likely the limiting factor.
You kept sending confusing and off-topic messages. Let's focus on the main issue. It seems you're mixing unrelated topics and trying to appear knowledgeable without providing solid evidence. Stick to the subject at hand and provide clear, relevant information.
My p6t deluxe (crossflashed to p6x58d premium) supports up to 2.4v when the DDR3 jumper is adjusted, which is generally considered a dangerous range where exceeding it can cause immediate failure. From my understanding, staying around 2.4v is essentially the limit where performance plummets and reliability drops sharply. My guideline for safe voltages, aside from the core voltage, is to use high-end boards like my p6t deluxe and keep the board’s maximum allowed voltage in mind—typically 0.4 to 0.5v under the board’s limits. My p6t supports 2.4v DDR3 and 2v VTT (IMC), while 2v DDR3 is acceptable. A 1.5v QPI is also acceptable. This rule tends to break down on older XOC boards that let you set instant death voltages like 2.1v core, as that severely impacts accuracy. For example, my DS4P lets me set 2.3v core, which is close to instant death for most 775 CPUs except the very old 90nm Pentiums that aren’t even meant to run.
