Ryzen 7 3700x Overclocking

[builder1909]

First of all, I've never overclocked a cpu or gpu, and don't know much about the topic.

 

I picked up a ryzen 7 3700x for my build, and feel as its under performing in single core performance. My favorite game, Rust, thrives on higher clock speeds, so I'm planning on OCing from 3.6 to a 4.0 (or even higher if possible) Problem is, I'm using a wraith prism stock cooler that came with my ryzen chip. Will that be enough? Currently getting about 40C idle and 55-65C in Rust. Any help/tips much appreciated.

Leave it stock, you will get better performance. My 3700x under full water cooling cant get above 4.2 overclocked and I actually lose performance. Just learn it alone and let PBO do its thing. You gain the best single threaded performance this way.

What's your RAM speed/timings?

Doesn't it have per CCX overclocking? You can probably just try that at like 4.2-4.4ghz and force the game to run only on the first XXC through CPU affinity in task manager.

Pick up a Neptwin(needs AM4 bracket) or Scythe Fuma 2 in the future in any event.

16gb ram set to 3200hz

 

You mean oc one core to 4.0+ and leave rest? Can i even do that?

 

Initially didn't plan on overclocking, so i didn't bother and stuck with wraith prism. Only now i started to think about it.

It should hit 4.2 or 4.3 all core. But Stock it should be getting 4.4 on single core. Are you measuring your clock while gaming? 

 

Another thing to check is your ram speed and timing. What ram do you have? Is it configured to run at it's advertised speed and timings? Ryzen really likes fast and low latency ram.

Well i know I have 16gb set to 3200hz. How do i check timing?

CPU-Z or Ryzen Master will tell you.

I don't really know what I'm looking at, but

CAS latency: 16

DRAM frequency: 1599.6mhz

Long as it's stable you're fine, just try the CPU overclock then.

You can just use Ryzen Master for it, just turn off any RAM changes in it. Shouldn't need a restart.

That's decent but not great. If you don't get the performance you're looking for from CPU overclock you can try overclocking the ram or trying tighter timings.

Alright, but 1 core to 4.0 or all?

I tried ram oc. Highest it would go was like 3333 and after that it wouldn't boot. Really spooked me good when my pc wouldn't boot, luckily all i had to do was clear CMOS. Anyway, left ram speed at 3200hz, don't really know how to set it higher without booting problems. And as to timings, how can I change those?

What voltage was it set to when trying the OC?

 

Also double check your infinity fabric clock is set the the same as your ram speed. If it's not it can really hurt performance.

In the BIOS (it will be different places depending on what board you have) or using Ryzen master.

When I first did it, I didn't really know what I was doing, I just tried higher and higher speeds until until it wouldn't boot. Not sure of the voltage.

 

Memory clock and fabric clock both set to 1600 mhz. Is that correct? I thought my speed was 3200hz (set in bios)?

What is it now? If it's 1.2v (the default) it's no surprise it would't OC. For 3200 and beyond it should be 1.35v.

That's correct. DDR means Double Data Rate. Double 1600 is 3200. Some places the actual clock is reported, other places it reports the effective clock. I don't know why.

Ohh, thank you that explains a lot.

 

XMP profile rn is:

3200hz at 1.35v 

I didn’t voltage change it at all, it was like that when i went to like 3400hz (pc wouldn’t boot past 3400). I guess thats my default, so if voltage isn’t the problem, what is?

You really don't need to go past 3200mhz CL16 to start, you can go up to 1.4V easily though.

 

Mostly just overclock your CPU as much as possible.
