Sane for a single threaded app. 16 threads no..

It ran cine @ 4.3 1.45...not spectacular but this chip is not spectacular anyway....3.9 stable air not a penny more...

if you are trying to match intake and exhaust, you need to match all the fans flows and pressures.
I have attempted that - in my experience - a case with open back -my S340 example :




and all intakes - seems to work the best(for me for the last 10+ years); because as people see it "hot air" doesn't actually move that much "HOT" air - you have airflow which negates
the hot part - as right now, you are trying to cool with the "hot air" ; you have less temp delta to cool the water with.
and you will not have many hot-spots (dead, non-moving air) with all intakes

This gets tricky. You have focused airfow into the case with those vent ports. In that instance, you are directly cooling the components so they will cool the best with *cool* outside air blowing on them. That's also why radiators work better as intakes - cool outside air. That test you refer to was posted on Youtube and he tested every permutation. The one aaveat he found was the *type* of colling used by the GPU had in impact. Whether it was open airflow or directed (pulled out of the case through the GPU cooling fins). I think the latter had slightly higher temps when the water radiator was set to intake.

If you have to rely on passive cooling of internal components, I think exhaust config is marginally better (I would need to dig up references). Otherwise, getting cool air directly to components is better. I still prefer the rear fan to be an exhaust (I currently run air cooling and want the heat from that moved out and not randomly dispersed.), otherwise I have a lot of fans pointing inward. I'm going to see if vent shrouds like you are using are available aftermarket. They should be and would be a great addition...

Anyone on OCN do custom wallpapers and build stickers like for psu and what not?

Agreed, people are entitled to free expression of any viewpoint no matter how ubound to reality it is. I'm just a pragmatist and like to call out things in defense of facts. Sometimes people consider me rude but I do try just to avoid sensationalism and incorrect info. I dont cares whos speaking/typing it.

I know many people are not able to get the Tridents up to 3200 but they are getting 2666 with 12 cas, some have seen 2933 at 14. I am not guarantying you will get the memory I have running at 3200 but the good news is you know at least one person who does.

Thanks for the info.

I will buy it in may, yet I am waiting for prices to fall.
A week ago 3200CL14 RGB was around 185€, if I get it under 190€ I will go for it.
Then I was thinking to get X370 gaming 5 from gigabyte, well K7 is only 20€ more...
And CPU probably R5 1600 ( maybe R5 1600X), depends on prices.

Currently doing my first atempt at overclocking this 1700x, 3.9 @1.4v was a no go (crashed after 10 min blend test in prime). Currently up to 1 hour of 3.8 @1.4v, but I'm not sure if I should crank it back up and increase the voltage or keep it at 3.8 and just lower the voltage. What do you guys think?

temps are as follows:

Going back to what started this whole air vs. water debate...a guy was asking about what he needed to cool a 1700 for help with a purchasing decision given that he already has an Evo. My stance was that he does not need to spend the extra money for reasonable overclocks. I stand by that.

That said, I don't disagree that custom loop > AIO > Air

I bought and Asus Crosshair VI+Ryzen 1700+corsair lpx vengeance 16gb(2x8gb)3200Mhz.
Sadly for cooling i have just stock cooler(wraith spire),i had previously on my old system and hyper 212 evo and read that was same as this one.
My 2 request advices would be wich cooler to get.My first choice would be Noctua nh-D15.Is an AIO better than that one?My 2nd point is the psu.I have a Corsair RM650x and for cpu i had just the 8 pin and not the +4 one.For overclocking do i have to change my PSU?

I tryed some OC,didn't succeded to get more than 2400 stable for ram and 3.8Ghz on cpu.
My settings are:
CPU core voltage 1.33125(affraid to put cpu on high voltage as i do not to have a short life but willing to listen to advices, i am just a beginner in oc)
VDDSOC voltage override 1.20
DRAM voltage 1.35.

Thank you for your help

Then this happened.

My corsair h100i v2 is worth its weight in gold with my overclock. An air cooler is not sufficient especially during the summer. If you live in a cold climate I agree with you, but fact is id never be able to keep my processor under 60C without my aio water cooling setup. I know people praise some of the Noctua brand air coolers but honestly water is where its at for consistency. It is a fact for me in NJ tested over many years. Some people dont have the luxury of cold ac in the home all the time and it vastly affects overclocks during the summer.

4 GHZ is a pipe dream for me on an air cooler, with this h100i v2 I could stay at 4 ghz if I wanted to, but I decided not to 24/7 due to the voltage, im happy at 3965 1.38 voltage with no LLC, this 8 core is going to chug away at games for years to come biggrin.gif

Challenge Accepted (Click to show)

So, I turned on the baseboard heaters, and turned up the voltage until I got out of my comfort zone...which was 1.425V, with overshoot being above 1.50V. I couldn't pass IBT AVX Max at 3.875GHz. I settled on 1.400V @ 3.85GHz for this test.

Initially I was going to get it 30° in my apartment and do my testing, but in the interest of not wasting power (or sweating my balls off), I did my testing with an ambient of about 25°C (~23.5°C closer to the floor). If you want to correct for summer temps in places with no AC then go ahead and add 10°C to the ambient/load temps. The delta should be the same.

Case temp near CPU air intake during run:

BIOS 0604 Settings:

- CPU: 3850MHz (154 FID / 8 DID) @ 1.400V (Offset + 0.2125V)
- LLC: Level 1 VCore, Level 1 VSoC
- RAM: 2400MHz 12-12-12-32 @ 1.25V, SoC @ 0.93V
- Everything else: Auto

System draw @ idle: ~95W

IBT AVX: 13 runs @ 12587MB, ~1 hour

- Speed: 180.5 GFlops
- Total system draw: 305W peak
- Ambient: ~24°C
- CPU: 71.4°C, VRM: 63°C, Chokes: 84°C

Didn't get that error this time which is nice I guess.

Warning: Spoiler! (Click to show)
So...if you plan to run IBT AVX on maximum @ 1.4V and pump out >180 GFlops (210W above idle) in the summer time, and you're okay with, say, 80°C CPU temps, then I say an Evo is enough. Again, I don't disagree that an AIO or custom loop wouldn't give you lower temps or that lower temps aren't a good thing. But do you need to spend another $100+? That's a personal choice. I'm just providing some real world data.

I also started up F@H to provide some data on a more realistic scenario. Heater's still on right now and I'm seeing over 24°C where I measured before on the side of the case.

F@H, ongoing

- CPU Usage: 78 - 89%
- Total system draw: 225W
- Ambient: ~24°C
- CPU: 62.0°C, VRM: 47°C, Chokes: 62°C

Aaand I went ahead and paused the folding to get a couple Cinebench 15 numbers just 'cuz.

Cinebench 15

- Performance Bias in BIOS: Auto
- Single Thread: 156
- Multi Thread: 1702

Warning: Spoiler! (Click to show)


So to summarize:

Is a 212 Evo sufficient for an 8-core Ryzen @ 1.4V during IBT in the summer? Yes.
Is it sufficient for even higher voltage in a more realistic scenario? Yes.
Is water cooling better than air cooling? Yes.
Are lower temps better for your CPU? Yes.
Is a 212 Evo sufficient for "extreme" overclocking? Probably not...but I wouldn't recommend it for that case anyway.
Does bardacuda have dust bunnies under his desk? Yes.

EDIT: Forgot to set folding power to "full" for that test. Took another pic with it on full, but the heater is off now so ambients are a little lower (maybe 1°C). It doesn't seem to be stressing the CPU any harder anyway though.

Warning: Spoiler! (Click to show)

EDIT2: Found a better work unit. Measuring 23.5°C on the side of the case at the moment.

I've always ran air, I had a thermaltake Frio on my other rig before this one. I plan on doing a custom loop when I get all the fittings and what not.

AIO coolers work pretty well and are usually as good if not a bit better then the best air coolers. Custom water cooling makes the biggest difference but its a massive increase in cost so not the best bang for the buck. I have ran air, phase change cooling, AIO and now custom water cooling and they all have their pros and cons. I like the custom water cooling just cause it's easy to add or modify and it's pretty darn quiet which is something I desire with my rig these days. My 1700x is my current rig and I found 3.9 to be the limit for me so far despite being able to cool the chip easily, just not willing to pour more voltage at it.
post #9820 of 11538
As far as price vs performance, there is no equal to the 212 Evo for $30.00. If one wants to push there cpu to were no man has gone before then water is better, but more costly. I would rather have a gtx 1080 ti, and the savings helps me do that. Each to there own, what ever floats your boat.
