Weekend benching with Hynix AFR... Took me quite a while to figure out that tRC=65 and tRFC=530 are minimum values that I could set, otherwise system will auto reboot in less than 10 minutes.

owikh84 | ASUS ROG Crosshair VIII Hero-WiFi | G.Skill TridentZ RGB DDR4-3200 CL16 (Hynix AFR) 2x8GB | DDR4-3533 CL16-19-19-40-1T @ 1.45V | vSOC @ 1.025v


As a comparison, here's AIDA64 score at stock RAM speed of DDR4-3200 CL16-18-18-38-1T @ 1.35v:


2x8GB Samsung B-die + 2x8GB Hynix AFR @ DDR4-3200 CL16-18-18-38-1T @ 1.35v

BIOS auto set without manual tweaking, AIDA64 lower read, higher copy, higher latency due to some loosen auto subs.

Taking a break from RAM OC, now let's talk about CPU OC

PBO auto: - CB R20: 4674 cb


PBO auto, vCore offset -0.125v: - CB R20: 4816 cb


PBO manual, 200MHz OC, PPT 395w, TDC/EDC 255a: - CB R20: 4840 cb



Manual OC 4.2GHz @ 1.200v - CB R20: 5042 cb


Manual OC 4.25GHz @ 1.232v - CB R20: 5101 cb


Manual OC 4.3GHz @ 1.25v - PC auto reboot with CPU overtemp error

Edit 26/4:
Manual OC 4.3GHz @ 1.275v - Finally able to complete CB R20 with XMP off (auto RAM)


Need at least 4.4GHz to match my stock 9900KS: - CB R20: 5277 cb

1080p Gaming Performance of Max OCed Samsung B-die vs Micron E-die vs Hynix AFR

Overall no significant difference but in terms of total fps B-die > AFR > E-die.

Did a quick run on my 3600. After seeing several benchmark results, probably gonna try to lower down the voltages and see if it's stable.

Update: After dropping it to 1.28v, achieved higher score.

Finally able to do 4.3 without overtemp protection error.
I reduced the vDIMM down to 1.3v, vSOC 0.975v, VDDG 0.9v, VDDP 0.7v.
CPU phase control set to default instead of extreme.
Put case fans above DIMM slot and VRM, as well as a small fan under the CPU socket.

3700X 4.3GHz all core @ 1.275v

Fixed voltage is not a good idea actually.
Rather work with offsets.

Good news for B-die lovers, ADATA 3600C14 @ 1.45v is coming to our local market soon.



For record top binned B-die was G.Skill Neo 3600 CL14 @ 1.40v, even better than 3800 CL14 @ 1.50v kit.
However, this kit is now EOL and replaced by 1.45v model.

Now available on Shopee for RM1,049
1 set left only, very limited indeed.

Nice! Almost the same price as TridentZ Neo F4-3600C14D-16GTZNB ~ RM9xx-1k+.

Not sure if local distro (BuildTech) is going to bring in Team's T-Force Xtreem ARGB or not but just realized that our friends at Pokde.net has tested the kit two months ago. Currently in local stores you can only find the 3200 CL16 models.

what are your PPT, TDC, and EDC values while running at this?

i'm a 3600 user as well. can't even go all core clock 4Ghz stable. sighhhhh

Here you go.

looks like you hit the silicon lottery!

best results for me is PBO + Auto OC200mhz with offset -0.1 voltage

I learned a new word today

But then from what I researched before getting this chip, the initial batches of 3600 are not overclockable standards.

anyone try pushing their Infinity Fabric Clock? max i was able to push to stable is 1867mhz. Memory running 1800mhz.

My 3600X was a dud, FCLK at 1867 only no matter how much voltage I have put.
My 3700X is a totally different chip, supporting up to FCLK 1900 easy.

Keep it synced. Max so far is 1900. The Apus next month will be able to do at least 2000.

Manage to go 1867mhz for both infinity fabric and memory. Can't go 1900mhz. Both cpu and ram not stable at 1900mhz.

Anyways memclk and fclk is thr only overclock i did. Pbo disabled and voltage left back at auto.

my 3600 is like the worst binned ever. fclk cannot go above 1867, all core clock can't go higher than 4.0Ghz.

anyways, just to share some findings over the weekend. using offset -voltage without pbo, you will lose performance for single core or non multithread applications.

try to do a single cpu cinebench test. i suspect you will have lower results at lower voltage.

Not sure what's the highest I can go but you can see my past 2 benchmarks in cinebench.

Possible the 492 score is when I set it at 1.25v
