Can I increase the speed of a 3000MHz RAM stick to 3666MHz?
Can I increase the speed of a 3000MHz RAM stick to 3666MHz?
I understand you're wondering if it's possible to maintain stability at 3666 MHz with your setup. Let's check the voltage requirements and system compatibility.
Its possible, if maybe unlikely.
BTW OC ram on an Intel mobo yields very little by way of performance increase. If it were Ryzen i'd say yes, try an OC, but for Intel , it hardly makes any difference, except in benchmarks.
The main point here is: No-one can tell you what voltage to use or settings to dial in. You need to trial and error and figure out what works best for YOUR dimms. All kits are different. What works for one set, might very well not work for another. TBH though going from 3000 to 3666 is too big a leap. Maybe 266mhz increase, but 666 is a bit of s stretch. Otherwise everyone would just by those 3000 dimms and OC them to 3666. The manufacturer would be shooting themselves in the foot. At 3000+ the mem will have a voltage (normally) of 1.35v To get it to go to 3666 you will have to give more voltage. This may harm your DIMMS.
Research your ram modules/mobo and you will find out how to OC the ram.
Ram is constructed from silicon, similar to CPUs. A specific number is confirmed by the manufacturer, for example 3000, meaning any ram in that group should function properly at stock voltage and operating at 3000. It's usually a bit below the maximum capability. However, due to being made of silicon and produced in batches, it contains certain impurities that influence timing aspects—primarily over 40 points. A single hit instability is the only risk, setting the upper limit. The actual performance could be around 3000 or 4000, but determining the exact value remains uncertain. This situation is referred to as the silicon lottery.
