Is there a way to boost the 1333mhz ram speed?
Is there a way to boost the 1333mhz ram speed?
Hey everyone, here are the specs I’ve got for my PC right now:
CPU: FX-9590 (not overclocked)
Motherboard: ASRock 970A-G/3.1
Radiator: H100i V2 240mm
Case: Rosewill GUNGNIR X ATX Mid Tower
Memory: Corsair Vengeance 4x4GB at 1333MHz (planning to upgrade later)
GPU: Geforce GTX 760 with 2GB ACX 2.0 cooler (upgrading soon)
Storage: 500gb HDD plus 1TB HDD (still waiting on SSD)
Power Supply: 950W, brand unknown
Additional notes:
- Airflow: The radiator is front-mounted to utilize room airflow, but the exhaust fans are on top and back. I’ve noticed my GPU getting hot, and the exhaust fan above it doesn’t seem to pull air effectively. I’m considering if pulling air in through the back and exhausting it out behind works better.
- RAM: I’m thinking about upgrading to higher speeds, but I’m not sure how to get timings for my CPU since it’s at 4.7GHz base clock. My motherboard supports 1600MHz, which is the max it can go to. If I want to increase it further, I’ll need to find the right timings.
In general for FX, more bandwidth is preferable to tighter timings, though compared to APUs the impact of faster memory on FX performance is modest:
Adding just 8.5GB/s increases speeds by roughly 12%. The jump from 1333 to 1600 is only 2.1GB/s, which translates to about a 3% improvement.
Different RAM overclocks perform better in various ways, and some are unaffected by increased voltage (though higher voltage might help with tighter timings). It’s best to test your setup to see what works for you.
The northbridge is responsible for the PCIe controller; you might need to boost the memory controller's voltage as well, but this could cause the CPU to overheat rather than improve performance.

Yes, even increasing it by 8.5GB/s only boosts things by roughly 12%. Moving from 1333 to 1600 offers just 2.1GB/s, which translates to about a 3% improvement.
Certain RAM overclocks perform better than others, and some are unaffected by additional voltage (though higher voltage might help with tighter timings instead). It’s best to test your setup to see what works.
BTW the northbridge only manages the PCIe controller. You might need to boost the memory controller’s voltage as well, but this would likely increase CPU heat rather than improve the northbridge performance.
Isn't the FX series best matched to 1866 RAM? I might be mistaken, based on what I understand of the 8370, but I've heard that gains beyond 1866 are minimal. Also, on my 8370 there seems to be an unusual relationship between HT Link and NB Frequency, and RAM. They should match, with RAM being about one-third of the NB Frequency. The maximum suggested HT Link is 2600, which gives us 2600, 2600, and 800. Please let me know if I'm misunderstanding!
