Thinking of buying this:

R5 3600
MSI Tomahawk B450 Max
Gskill Trident Neo 3600mhz 32GB (2x16)
WD Black SN750 500GB

I just need the thing to work out of box, no tweaking, no overclocking.

Comments?

can consider changing mobo to b550

Go for B550 motherboard now. I dont think the price different between B450 and B550 for the same MSI Tomahawk-series will be more than $100 plus you can future-proof abit when if buy a pcie 4.0 ssd in the future.

Those temps look ok. Btw. How much did you undervolt ? I tried 0.05 yesterday, not much difference to temps though, and at the same time lost like 80 cinebench points


I drop my CPU Voltage to 1.35, thought of trying 1.32 or 1.3 later... i assumed if the voltage is too low, the rig will not even boot right?

You doing static OC or what? I was referring to negative voltage offset.

you got turn on pbo? :o

set values manually and should see increase results.
iirc is in 2 places
nbio common option/xfr. set ppt: 280 edc: 200 tdc: 200
amd overclocking, autooc +200mhz

Got it. I read that once you set stuff at the AMD oc submenu, that you can't change it after aside from a bios pill of sorts. Valid still ?

I am using the same mobo as you but on rev 1.1. I left my Vcore to "Normal" and offset at -0.0685. Performance was on par with Vcore on Auto and load temps went down by at least 7degrees.

I must say YMMV due to the silicon and you are haivng 3950X where I am using 3700X

ya heard of it, so i never touch settings in amd oc, except for the autooc +200, which cannot be found eslewhere

Actually yesterday I did a test... No difference in speeds and benches with the offset but max temps reduced by 1.5c. idle also 1.5c. maybe I'll try ur offset value.

On a side note, my trident 3200 rams:
1. Clock is running 158x MHz. Never reaches 1600 even on load. Bios setting ? Fclk is 1600 so that's ok.
2. Trc value. It's now 78 but my xmp is 45 I think. Safe to put to 45?

EDIT: I tried your offset value and I got a bump of around 60 CPUZ points and around 50 ** R20 points. Was able to get a good 35-40mhz more clocks as well.

Temps are also down by a good 1C :)

Anyone knows if setting only negative voltage offset without OC (others on auto) will lower the performance level?
Because read online that some people said it will.

I'm playing with what you have just described.

1. Voltage offset : tried Neg 0.05 then 0.068
2. No Auto OC
3. PB set to Auto, PBO off
4. Memory XMP
5. Everything else Auto

@ neg 0.05 - all I saw was 1.5C reduced idle and load temps
@ neg 0.068 - Temps dropped by a further 1C, small tiny performance boost but consistent. (**, CPUz, clock speeds all up by a tiny notch).

I'm most amazed by the temp reduction to be honest. Right now, I can idle as low as 38C...

EDIT: Just as I was type this PC BSOD HAHAHA. So now I'm going with 0.0625

think i will not play with that, or PBO. Happy with the processor the way it is :s22::s22::s22:

just do it! =:p
pbo is no different from xmp, probably safer as regulated by the cpu parameters.

pbo + ram oc can extend around 10% more perf.

as for your 158x ram is because you tun on svm in bios for vm purposes. iirc, it makes your pc boot up in virtual mode and bclk will always change at each boot, so results are not constant, could be why you saw the tiny 'boost'.

i also on svm, same thing. :o

its ok, i think i stick with PB2 for now, save the testing of PBO for another day. I need some entertainment. hehe

good shout on the SVM. Yes, i have that on.
