OJR, yes for now. Waiting to see when Zen 3 becomes retail.
My new 3800X, sitting stable now with manual OC, CCX0/CCX1 4400/4450MHz @ 1.35V.
Memory OC'd to 3800 CL16, 1900 Infinity Fabric
Ryzen 7 3800X
MSI X570 Tomahawk
32GB G.Skill TridentZ RGB 3200 CL14 (2x16GB B-die's)
EK Velocity WB with 1x 360 and 1x 420 rads
These things are hot and hungry.. not impressed with this EK waterblock although maybe it is a bad mount, reaches up to 87degC stress testing with OCCT, but typically only up to around 75degC while gaming and usual workload.
I think I could hit 4.5GHz with better cooling and more volts. Going to order one of those new Optimus Foundation blocks.
Those optimus blocks interest me. Never heard of them before but they certainly talk up a good story on their performance and manufacturing. Now it is something I am definitely going to think about. Is there an Australian outlet for them yet?
That temp seems high for that voltage, what pump is it, at full speed? The flow is definitely the right way?
They look very well built with optimal design to cover the full Ryzen IHS. Initial user based results are that they perform a few degrees better than the Heatkiller IV Pro blocks which are already top performers. No where to get them in Aus yet, I will order direct.
Yeah does seem a bit higher than what I was expecting. EK DBAY D5 PWM Pump/Reservoir Combo, inlet/outflow flow is correct on the WB. Pump speed set with min 50% and ramping up to 100% speed at 75degC, same with the rad fans.
I think I will try a re-mount this weekend.
Yeah, your setup looks fine, I think it would be worth testing with the pump pwm at 100% though, at least see if it's worth ramping it a little sooner as pump pressure can make a fair difference.
please tell me your flow is running up ^ GPU -> CPU? - just because impingement plate is inlet
apology if stating obvious just not familiar with that pump res flow -->
think it will run a shitload better if you swap those CPU hoses around
(flow from top down right?)
The inlet/outlet are correct on the WB.
Flow is Res/Pump > GPU > CPU > EX420 Top Rad > RX360 Front Rad
Edit: just ordered the Optimus Foundation CPU Block - AMD - Acrylic + Black Aluminum / Pro-XE Nickel.. $270 delivered, ouch
While I wait for it to arrive I'm also going to try put some extra nylon washers on the current EK WB and remount to see if it makes a difference
Ok cool, just reverse to what I normal do.
And the GPU block works like that, pictured inlet on right?
The ones I have used all have inlet on left.
All EK GPU full cover water-blocks require inlet to the left, not to the right - as pictured above - for best cooling performance.
Example of written instructions from EKWB:
This is not the same GPU block I am using.
I have the EK-FC Titan X Pascal - Acetal.
The instruction manual states "You can use any opening as an inlet/outlet port".
I might still play around with the loop on the weekend and change the order so it flows Res/Pump > RX360 Front Rad > EX420 Top Rad > CPU > GPU
well there you go, sorry man just looked amiss. Ag
75c gaming does seem pretty warm. I offset my voltage -.075 on 3900X still get full boost, but runs a dam site cooler than stock V
All good, something might still be amiss. Just verifying everything is correct as per manufacturer instructions, so nothing obvious just yet.
What temps do you get running OCCT? Are you able to fire up OCCT on the default large test and run it for 10 min and let me know what your max temps are?
Gaming wouldn't go over 50 this time of year.
di entropy, what ambient temp is that room the rig is in?
Any discussion about temps overall must consider this factor.
I stand corrected. Apologies for the wrong info.
If this helps you figure out what is going on, I posted this CBR15 score recently with a $69 Byski CPU block:
Never went over 60 degrees.
Very nice OC and timings, best bit is was all done on a X370 ftw! gg
got a pic of your block somewhere, or same as mine?
Yeah that little strix is so underrated.
Pic of bench:
CPU block on there is this exact make/model and a 1080 Ti in the same loop:
yes same block, put it up against ANY other, pure size of cold plate/fin density and free flowing
the impingement plate & fins literally overlaps the entire IHS - outside that you have water channels around entire outer edge
