1700X OC depends on RAM?
1700X OC depends on RAM?
Hey everyone,
could Ryzen overclocking performance vary based on the RAM type? I'm using Corsair Vengeance DDR4-2400 CL14 with A-XMP enabled. It seems I can't reach 1700X over 3.8 GHz. The 1.38V version works fine, but the 1.35V one is quite stable. Going to 3.9GHz or higher causes voltage drops during OCCT stress test.
The reason I brought this up is that OCCT indicates my CPU remains idle at the start of the benchmark and only memory begins loading, which leads to crashes at around 70% memory load or higher. At that point, the CPU doesn't move.
Best regards,
Martin
I have a 1700 (non-X) model at 3.8ghz on the stock Wraith Spire cooler, and it's operating smoothly without any issues. I achieved this without modifying the RAM and simply increased the multipliers up to 38. Currently, it remains stable, and I haven't attempted higher speeds since using only the stock cooler.
On the other hand, my concern is achieving speeds above 2400mhz with the RAM at 2133mhz. I've struggled to push it beyond 2400mhz despite having the Corsair Vengeance LPX 3000mhz RAM and updating the BIOS on an Asus B350 motherboard.
My belief is that RAM speed isn't directly linked to OC speed, which means unlocking doesn't necessarily improve performance.
Hello!
No lack of RAM affects how Ryzen overclocks, but it can still benefit from improved memory speeds. The quicker the RAM operates, the more efficiently Ryzen functions since it relies on communication with the RAM through CCX technology.
Hope this helps!

Well, I have a 1700 (non-X) sitting at 3.8ghz on the stock Wraith Spire cooler and it runs just fine. I did that with out even getting into the RAM, and just basically took the multipliers up to 38. It's sitting around right now just being stable, and I have yet to try going higher since I am using just the stock cooler.
However, that's with the RAM at 2133 mhz.
My issue is with getting it faster than 2400mhz on the RAM - I've been completely unable to get it to post at anything faster than 2400 mhz (and I have the Corsair Vengeance LPX 3000mhz RAM, and running latest BIOS on an Asus B350 board).
My point I guess is that there isn't anything tied to RAM speed and OC speed. OC speed is independent - hence the benefit of unlocked multipliers. Some Ryzen CPUs are better than others - but the limits that we're finding is right around 4.0-4.1ghz.
Also - remember - this is a full 8-core 16 thread CPU on a brand new architecture... and you're trying to push it faster than it was designed. Your mileage will DEFINITELY vary.
