Is it even worth over locking a 1800X

smogsy · 14 Aug 2017 at 07:48

So I got an 1800x

I played around with over locking 4Ghz is pretty much out the question regarding voltage.

3.9 was "stable" at around 1.320v but got fails booting sometimes.

3.8 is stable it appears at 1.320v and works with out boot issues.

Stocks boosts to 3.7 anyway and reaches 4.1 without issue.gigabyte voltage was 1.468v

I've got down to average of 1.268v high of 1.332v after 90 minutes CPU/GPU stress testing

I'm just wondering if it's even worth overclocking if I can only reach 3.8? At a good voltage

My work load varies between:
Games
Rendering
Encoding
Compiling
General multitasking.

Probably not going to notice that much but I would expect those last 4 tasks would benefit the most from an all core overclock. Try out rendering,encoding and compiling stock vs 3.9. I went with a 3.925 all core overclock on my 1700x, with around 1.38v. 1.32V is pretty low, anything sub 1.4 is fine on these chips.

Also worthwhile getting the memory as fast as possible.

i thought 1.35V was the limit with 1.45V getting lower life expectations?
also regarding the Temps what should i stay under at full load 70C?

ram is running @ 2933 but thinking of getting some faster B die Ram

1.4 and below is fine but its a trade off with temps when pushing it that far. Real world usage your not going to notice much between 3.8/3.9/4.0.......but its always nicer to have higher numbers.

IMO, yes. It's free and for me it was fun to do now the BIOS's are good.

If you don't have the time or the patience, then concentrate on the RAM, that's where you can gain buckets of performance as there's a bottleneck under 3200MHz and tighter timings give you even more performance back.

I would suggest getting some 8Pack Team Group RAM and tuning to one of the following for example (with tightened seconds):

3200MHz 12,14,14,14,32
3333MHz 14,14,14,14,28
3446MHz 14,14,14,14,32

Once you get that down, you can make up your mind whether you want to push for 4GHz on the CPU. Which for me was a piece of cake on the ASUS ROG CH6 and well under 1.4v

What motherboard do you have?

-Is on a forum called overclockers, asks if its worth overclocking..

FredFlint · 16 Aug 2017 at 14:15

I don't bother, I got the 1800X so I did not have to overclock as it takes ages and the difference is small for most things. You also don't get XFR for single core so it can be slower for some things. I would have got a 1700 if overclocking as it will likely get to the same clocks at a lower price.

My 1800X needs ~1.425V for 3.9GHz to be stable. After doing some tests TBH it's more 'optimal' at stock, as I dd not breach max XFR of 4.1GHz.

For example when gaming I'm using FreeSync and capping to 88 FPS as the MG279Q has FS range of 35-90Hz, now stock vs OC'd I have no discernible difference in 'experience' all feels the same for FPS, etc. Next say I was running encoding, f@h, etc, stock all cores is 3.7GHz, uses ~1.25V. This is very power efficient compared to OC and thus very cool and quiet on air cooler. Now a step up 3.9GHz is a massive jump in VCORE and power usage, heat output, etc, etc. Performance increase is what ~+5.5%, if scaling is perfect, but the power, etc used is nuts. I have noted in stock operation depending upon loading and temps 2 cores go up 4.0GHz, which again is handy as I can't attain that as an all cores OC.

The R7 1700 is the one to OC IMO. Stock all cores is 3.2GHz, so 3.8GHz ACB OC is nice healthy boost. Voltage wise on CPUs I have ~1.35V (+/-0.02V), not as huge a jump on power usage as the 1800X 3.9GHz. All the R7 1700 do 3.7GHz at stock voltages ~1.2V (+0.05V on some). Which again is very close to max XFR of 3.75GHz on them.

I would say it's worth OC'ing a 1700X as well, but again the R7 1700 is better purchase, especially taking the Wraith Spire RGB into context.

So for 24/7 use just doing RAM clock increase and timings tweak on R7 1800X. If I did have a golden 1800X and really needed the ACB OC of 4.0GHz+ then yeah I'd use.

What motherboard do you have?

Gigabyte Gaming K7 (never again...)

ATM 3.8 is Stable at 1.248v however at 100% load this is at 61C (noctua DH15), from what i hear 70C is the max? unless that was including the offset....

the plan was to grab some 8pack ram, but not everyone is able to get it working at 3200.

61c is fine and I would assume that's without offset. Mine hits 70c on the nose when stressing. IIRC 95c is the Max and in my opinion, just keep it under 80c when stressing which would be a fair bit lower in normal use.

Putting your 1800X in a sewing machine doesn't sound particularly healthy for it.

Have you monitored voltage at stock when XFR kicks in? I remember it jumping to almost 1.5v. Has this changed through BIOS updates do you know?

gupsterg · 17 Aug 2017 at 14:07

Yep hits 1.5V, but as its low core count, its low amps/watts draw and non issue.

Why AMD OC doc states lower voltages for OC is because we do all cores OC, so higher amps/power draw through silicon.

~>Dg<~ · 17 Aug 2017 at 15:51

to be honest you will be lucky to get 4ghz stable 24/7. as a gamer im surprised you didnt go with the i9 7900 tbh.most games will be quite a lot faster overall and some are upto 30 fps faster .

Great thanks I did wonder about this.
I'm at 4ghz 1.35v but the extra heat it generates overall doesn't seem worth it somehow for gaming. The max temp never goes over 60c but the room always feels hotter (could by my GPU working harder as well).

I'm going to revert back to stock tonight and check if I notice any performance difference.

chroniclard · 17 Aug 2017 at 16:06

1.35v for 4ghz!? Thats some golden chip there......

breathe3asy · 17 Aug 2017 at 16:07

I'm on a 1.375 with a -0.025 offset pstate overclock,

CPU-Z says I'm running at 1.4v but HWinfo64 says 1.35v

Not sure which one to believe but the bios pstate overclock should be forcing it at 1.35

what is it not the truth ? this forums worse than csgo lol. 4ghz isnt possible for most stable.mostly its 3.8-3.9.

he is mostly a gamer i seen many posts for him looking for the fastest cpu for his gaming.which is the i9 7900x.which even a bad one does 4.6-4.7.most do 4.8-4.9.

@Rossi
i wanted an extremely quiet rig. Due to the HUGE wattage i9 require that's not possible.

I got the 8pack Kit on the way and settled for 3.8Ghz @ 1.248v for now, Quiet & Fast. Lower Voltages than "Stock"
