what do you think?
4200 all core at 1.2375v on air couldn’t get 4300 on 1.45v

With a water block
4350 @ 1.45v 82’c
4275 @ 1.325v

Not sure on what the safe voltage is.
1.45v is what call Asus auto. My Asus board on auto gave my 2500k over max voltage. Google showed some f.i.t thing saying 1.35v as max.


Ps could some put up a sticky on overclocking a 3700x?
Cos I’m a noob on my second build and don’t know what I’m doing :)

Wouldn't bother OC'ing it if you use it for gaming? OC's itself. Only reason you'd want an all core overclock is if you do a lot of rendering or tasks that require lots of cores.

If you use your PC for mainly gaming do not do an all core OC. My stock 3900X will get between 4400 - 4550 on 2x cores for gaming and even games with better core usage sit around 4400. So an all core OC is actually a step back for gaming. Run a few games and watch your core clocks, they should be higher than both those "overlcocks" above and use less power while doing it.

The only thing that is slightly different is your RAM is at 3600Mhz vs my 3200Mhz RAM. Also have you enabled PBO in the BIOS ? Gave me a bit of a boost on scores.

Yes PBO is enabled ! what memory are you running ? is it CL16 or 18 ?

Looks like you memory latency is slightly lower than mine but the higher bandwidth is helping a lot maybe ?

Im running CL16 on 2 x 16GB Corsair Vengeance RGB Pro AMD Ryzen Tuned 3200Mhz . Not sure as I just enabled A-XMP on the BIOS settings and enabled PBO.

i didt think that. But both my peak and avg voltages in rayzen master show 1.4+v and with the air cooler it was hitting 60c gaming and 70 for cinebench, it’s water cooled now and cinebench is max 60.

I still can’t find any info on safe vcore, googling “ryzen 3700x safe voltage” brought up recommendations by F.I.T 1.325v to 1.47v, seems a bit high considering 7nm and my 2500k was stock at 1.2v.

Rule of thumb. All core 1.325v is only safe for 50% of the chips, 1.28v is safe for 100% of the chips.
Thats why you shouldn't bother at all. Use 1usmus v.1.1 powerplan as per requirements for v1.0 file. (so PBO OFF)
The only addition, is activate XFR. Thats usually under AMD CBS in bios.

Your CPU would boost to what ever deems is safe at that point in time.

I've just got my system but auto enables vcore to around 1.48v should i change it to 1.28v then in bios? will it always be this vcore too even browsing?

It could go up to 1.5v on auto, but it will only do it on single core and for short period of time, best way to get extra omphh from ryzen is to oc memory and use either pbo on, or 1usmus power plan with xfr, as suggested above.

I’m thinking of getting a next gen Ryzen when they’re out Is the 1usmus plan really good? I’ve done a bit of reading and it seems intelligently put together. What’s XFR?

I've managed to get mine stable at 1867 flck (with 8 pack 32gb CL3600 ram at 1:1 with tight timings) but it needs 1.18 SoC voltage (the VDDG volts are 0.95 - anything else isn't stable), but at that fclk the CPU voltages seem high (1.48 while playing planetside 2). So I found my chips FIT voltage using prime95 and have just set that in the bios (1.28) and left PBO on. My clocks now boost to 4300 in planetside insted of the 4200 I was getting at stock. Temps are lower also.

I know it won't explode, but is it safe to run SoC @ 1.18v and a set vcore of 1.28v?

Just started using the 1usmus power plan (C-States enabled / PBO disabled) and am seeing 3 of my cores boosting to 4425 which certainly wasn't happening before. Compared to a fixed overclock gaming benchmarks (Far Cry & Heaven) are giving the same scores if not slightly better but the CPU is about 8c cooler under load !!! Cinebench multicore scores are lower but as I primarily use my PC for gaming lower temps and longer life is trade-off I'm willing to live with. XFR is just the built in boosting algorithms that the Ryzen chips use.
