not so sure but has been reading/hearing that 1800x almost guaranteed 4GHz with decent voltage, & comes with better IMC.

not sure bout x370 as i have yet to test one, but of all 3 b350 boards i've tested so far, ranging from strix b350, giga b350m g3 & d current one - tomahawk, all have their fair share of bugs here & there. sadly i didn't get d chance to use d same chip on all boards, but cpu mileage wise they're almost d same:

strix b350 w/ r5 1500x - 3.8GHz with 1.3xv, ram max at 2933 (afr/mfr), 3066 doable once in awhile, any higher no go
giga b350m w/ r5 1400 - same cpu mileaage, & voltage, ram max @ 2933, 3200 doable once in awhile (afr), NO 3066 multi
msi tomahawk w/ r3 1200 - 3.9GHz with 1.3xv, ram max at 3200 (afr/samsung b), 3333 doable once in awhile (samsung b)

too bad no biostar in sg (b350/x370) else i really dont mind testing em, read bout their b350m which can do 3200 with afr/mfr weeks ago, tempted but too bad 0 availability here.

I think BIOSTAR boards still need a lot of refinements in terms of BIOS etc.
Also, lower-end boards always come with lower grade components especially the VRMs.
Good VRMs are Inifineon's IR3555 etc

For some reason my experience with ASUS X370 is the worse, and in the end board died donno why. LOL.

ASRock so far good. Gigabyte no chance to try, busy. Biostar usable but limited, and not cheap. MSI is generally alright but the UI is limited, the Xpower Gaming Titanium that I am using feels very limited.

Back to OCing the ROG Crosshair VI Extreme, now under water



DDR4-3600 16-16-16-36-1T @ 1.35V, SOC 1.2v is bootable, but not stable and lacks efficiency:


DDR4-3466 16-16-16-36-1T @ 1.35V, SOC 1.2v is Pi stable and gave me good bandwidths, but higher latency:


Heard IMC of Ryzen 5 is not as good as Ryzen 7...
Maybe I need to buy a Ryzen 7 1700 to unleash the full potential of the Extreme board

More results coming soon...

For 3600 that's very slow.

Here's my reading at 3333, timing similar as yours.

Ya, the scores are quite low for a DDR4-3600.
Maybe further tweaking is needed or it's normal for on a Ryzen platform. I've seen other people also getting these figures at such memory frequency.

Anyway, bought myself an Ryzen 7 1700 just in case it has a stronger IMC compared to Ryzen 5. Can't wait to get it!

1700 is my favorite. I think you'll like it too.

My 1800X sit there do work only, it's not the one I go to for playing.

Nice to see some NICE OC. New here. I have a 1700X. I'm currently Outstation. Trying to learn from the SS you guys post up.

I manage to OC my 1700X to 4ghz and everything stable BUT my webcam stutters when ever I use it or hangs. So I set it to 3.7ghz.

I'll post my SS when I get back.

One quick question for those who OC'd - does your Core VID show up at 1.550V after waking up from sleep?
CPU Core Voltage as reported by SVI2 shows the voltage I keyed in.

These are values from HWInfo btw.

Core VID is not the actual core voltage that your CPU is operating at.

VID at 1.55v sounds normal, your actual vcore should be lower than that.

Yeah that's what I thought too.
Voltage reporting is still rather buggy in Ryzen.

Fiuhh... Took quite some time to find the perfect voltages for my G.Skill TridentZ RGB DDR4-3200 C16 2x8GB.

F4-3200C16D-16GTZR @ vDIMM 1.40v, SOC 1.15v


AIDA64 performance:


Hynix-AFR is the IC inside, according to Thaiphoon Burner (RAM is not properly recognized and gave CRC error lol):

quickie with sammy b, but 3333 for 24/7 still no go...

Edited : already get 2933mhz ram speed with 3hour stress test

Just got my Ryzen 7 1700, C6H and Vengeance RGB 3466 (CMR16GX4M2C3466C16) on the 5th of Sept.



Have yet to tinker with overclocking the 1700, but got around to getting the RAM to run at rated speed and timings. Kit is Samsung B-die. All manually keyed-in inclusive of some sub-timings. Question to the sifus here, should I run at 3466 CL16 or dial it down to 3200 CL14 (tested working as well). Does the infinity fabric have a cap/ceiling? Read somewhere that it caps at 1600, which would suggest getting RAM to run above 3200 contributes nothing to the fabric?

Just use aida to test efficiency, d combination gives highest efficiency wins.

Roger that. Will do a comparison and come back with results.

For CPU OC, better to do in UEFI bios or use Ryzen Master from within Windows?

Ryzen Master is a useful tool to test your desired overclocked CPU frequency and find the best voltages for it, without repeatedly rebooting the PC.
Once you've found the suitable voltages for your OC and confirmed its stability, go into the UEFI and insert the settings permanently.

btw, I am using ASUS's TurboV Core v1.01.15 instead of Ryzen Master.

Noted will give it a try.. in your screenshot the cpu vcore voltage shows 0.27500 so using Asus TurboV we have to use offset mode only?

Can use manual vCore as well but for some reason with the current launch BIOS, the C6E has issue overclocking the Ryzen 7 1700 above 3.7GHz or vCore higher than 1.3V. CPU multiplier will stuck at 15.5x in the OS, inside UEFI it shows the correct OC though. My current workaround is to use offset vCore, then only multi above x37 will work in Windows.

It's a known issue for many other Ryzen mobos from other vendors as well, some including the C6H already received a fix BIOS to overcome this bug. ASUS BIOS engineers are so slow this time that it has been two months the C6E still hasn't get any BIOS update yet since launch.
