Hey guys,

So I'm running:

Ryzen 3700X
MSI X570A-Pro
16GB Corsair Vengeance RGB Pro (2x8GB) - CMW16GX4M2E3200C16 (16-20-20-38)

I've been able to get the memory running stably at 3400 with IF at 1700 to keep the 1:1 ratio.

What I haven't been able to do is tighten timings at all. This is the first Ryzen setup I've tried this on though and there are a million settings.

Anyone done any OCing on this setup, or at least with this specific memory?

I did download Thaiphoon and use DRAM Calculator to find settings that should work, but they haven't.

PS. I have already tried the red silicone sealer mod but it didn't work.

I have so many questions, what is "IF"? I assume that 1700 is SDR frequency based. So 3400 at the same timings? I would count that as an impressive win, but maybe that's normal? The only time I OC'ed some RAM on my R5 2600 B350 Tomahawk I got 2400 cl 16 running at 3000 cl 18. So it seems it's about the same 6% increase.

I just used the memory "try it" list, so clearly a noob when it comes to RAM OC, but saw a youtube from Gamer's nexus about their experience with tightening timings, and based on how long one can spend fiddling with these settings I am happy with my result.

Didn't know about the DRAM calculator though, maybe I should try that. Does it work on intel?

What is the red silicone sealer mod as it relates to RAM? Unless you just poking fun again and you mean you did it on the chip? Does delidding help RAM OC?

IF is Infinity Fabric - it's an AMD specific technology. It works best when IF has a 1:1 ratio with RAM speed . RAM is DDR (Dual Data Rate) so DDR4-3200 is actually 1600 x 2. So I OCed the RAM to run at DDR4-3400 (1700x2) and matched IF (1700).

In theory, as I understand it anyway, higher speeds would require looser timings. But I can't get my memory to run at tighter timings even at stock speeds. I think that's my ignorance rather than a hardware limitation though, hence the thread.

Ryzen DRAM Calculator was specifically designed for Ryzen overclocking due to Ryzen being to sensitive to memory timing changes - it opens the door to decent gains if you can do it right. It won't work for Intel AFAIK, but there's a decent amount of overclocking videos and such online for overclocking Intel CPUs - GamersNexus just did one in fact for the new Intel CPUs.

The red silicone was a joke. You can't delid RAM but you can add heatspreaders to help cool them, though I'm not aware of RAM ever getting too hot to function properly.

I is clearly noob, that's fine, I run at stock even IRL ;)

From all my extensive OC experience and youtubing it seems far more likely you'd be able to up the frequency than down the timing. Still I would think you could reach CL15 at least @ 3200Mhz. I'm sure I saw Steeeeeve had to drop his frequency a ton to also drop the timings.

Okay, so I've been running a 3900X and now 3950X on a MSI Meg X570 Ace motherboard and obviously overclocking it. For daily use, I try to keep the vcore as low as possible and at present my 3950X is 100% stable at 4.2ghz using 1.1875vcore. Yes I lose single core performance, but I don't really use it so I am fine with that.

What you want to do is to do is to start low on the vcore, between 1.2 and 1.25 vcore and see up to where you can push the processor. I found using the blender benchmark gives a ood indication of stability and a little shorter to run than prime 95 small FFT for an hour or so. Make sure you memory voltage is set in the bios, just to ensure that it does not cause any stability issues for you when testing.

I've been through a 3600, 2 x 3900X and 2 x 3950X processors and I'm happy with the one I have now. The previous 3950X was good, make no mistake but I had some stability issues when overclocked. It was however running a fair bit cooler at 1.3vcore compared to the 3950X I have now as this one would break into 90c using 1.3vcore.

In the end it is all about playing around with settings to find what works best for you. You want to keep temps at 85c max, preferably into the 80 to 70c mark.

Let me know how you going with your setup. Will be great to know.
