[Official] AMD R9 390/390X Owners Club - Page 339

post #3381 of 11900
Hello everyone!

First i would like to thank AgentSmith for starting this and all the members of the club that are always putting up OC results, infos and helping each other! I have been on OCN a few times for reviews but i've never heard of something like an "Owners Club" before, i thought this was so AWESOME that i decide to read every post of this thread whenever i could, took me 5 DAYS to get here and i didnt get bored at any time, it was really nice, like reading a book, and i would do it again! xD
I knew only the basics to OC, never tried OCing anything except for my Android, wich is a tottally different proccess and it doesnt take much experience. i've learned so much about vendors (GPU wise) clocks, voltage, temps (specially temps) and benchmarks (like NEVER use furmark haha)in this time that i feel like a pro! (Not really, just kidding) thank you all!

So, to my situation... My mobo died about a month ago and all my setup was some f-ing old parts so i just started my first real job and decided to do some serious money-saving and build a new rig from zero, regardless of the time it takes, i brand new PC setup its worth it, until there, just mobile frown.gif. The hardware im looking for are:

CPU: Core I5 6600k skylake
Mobo: Asus z170 pro gaming
RAM: 8GB DDR4 2133 (16GB later)
GPU: Sapphire Nitro 390 with backplate
Storage: 240GB Kingston SSD
CPU cooling: CM Seidon 240M
PSU: EVGA SuperNOVA 750w B2
Display: Benq xl2430t 24" 144hz
Case: Corsair Carbide Spec03
Already own from old PC: 1TB HDD, DVD optical driver, Xigmatek 500w psu that i'm aware that wont be enough and Asus HD 3850x2 dual GPU that reached its limit.
Went for the sapphire because it hás the best cooling, and by the time i get this rig will be the end of summer here in Brazil (i guess the exact time its winter in US), ambient temps reaching 40C in extreme days and dont want to let the AC on everytime i'm gaming. I stil have a few questions and i hope you guys can help me out.

1: My main use for this rig is gaming, and maybe some benching now that i got really into this thing. I'm a MMO guy, só i mostly ill be playing games that this GPU can nail 150+ FPS like FPS's, moba's, and open world RPGs, was always a console player but since im not getting an atual gen console, gonna switch to PC, how a good OC (1150/1650 maybe) its gonna help in real gaming performance? I know i cant expect +30 FPS gain but maybe 10 in hm... BF4?

2. I'll be playing in 1080p, maybe VSR 1440p, theres a need to go for 390x instead? And theres much difference between VSR and real 1440p performance wise? This question is cause i really wanna enjoy the 144hz feature só i plan on going 60+ FPS, maybe some 100 or max i can get.

3. This PSU can handle the i5 OC'ed to 4,5ghz and everything fine? Plan to buy a second 390 in a year or so and i know i would have to upgrade, what should i get there? 1000w min?

4. Do any of you guys know a shop that can ship for Brazil besides eBay? I have trust issues with these. Hardware here are overpriced, we are used to go on local Store, cause by shipping here
The prices are abusive. By my math, importing + taxes still cheaper than buy over here. And we dont have plenty of options, for WC for exemple... All i can find CM and Corsair.

Im so sorry for post lenght, but cmon, after reading the whole thread, i kinda deserve it right hahaha. Sorry for any grammar mistakes and thank you all again! Feel free to give your opinion in anything even not GPU related on the rig.

Did replacing thermal paste void MSI warranty?
My card also got some incorrect pad placing.
it plays under load 60-65c but it's better to make sure everything is OK inside.

I think the VTX 390 would also fit, looks to be more or less the same card as the VTX and Powercolor Turbo Duo 290s. These I think are about 267mm long, ie no more than the pcb and I think an SG13 can take around 270mm max? I think they have the same pcb as the powercolor pcs+ cards but run at lower clocks. Obviously being smaller twin fan coolers they are unlikely to be the best out there but from what reviews I did find they seem reasonable. A 970 may be a better option depending on priorities and pricing but something to think about anyway wink.gif

My 390 is going in an SG05, hence all the reading up on lengths, but I will be watercooling with an external rad...

I was wondering if some MSI 390 / X owners can state their VID and ASIC ratings, I'm just curious to correlate something I noted with 290/X. I was after results with factory bios and no OC present but factory clocks. Please use APP linked below for VID, best to take reading after a reboot and no OC app running in background.

That voltage relates to what the voltage chip on card thinks is 12v coming in.

I wouldn't worry about it smile.gif .

Voltage control chip is same as 290/X, all 3 290/X cards I've experienced do the same.

Now I wanted to see for myself if changing the TIM on the MSI R9 390 really does improve the Temps by up to 6°.

So I unscrewed the 4 screws holding down the GPU to the cooler and unplugged the fan from the PCB (I also unscreewed some screws connecting the backplate on the front side, but I am not sure if that was necessary).

I thought I would need to wiggle the card a bit as seen on some youtube videos but actually it came off really easy (mind you I took the card out without having turned on my PC for the whole day so it was cool).
What I saw was once I got a glimpse of the bare GPU core was really frustrating. Thermal paster all over the place and the viscosity of the TIM was really fluid. so probably cheap TIM with heaps of silicon in it. (just my guess)
Additionally I saw that the thermal pads on the VRams was not covering all perfectly. See picture below.


Warning: Spoiler! (Click to show)







As you can see. the TIM is all over the place and on the actual core had barely enough on it. It also looks like there was a major airbubble in the middle.

So I cleand everything off (which took me like at least 15 min if not longer) and noticed also some scratches on the cooler. (See picture below)




Now I changed the TIM (used Gelid GC-Extreme) put everything back together and plugged in the fan (actually I nearly forgot to plug in the fan again doh.gif )
I used the spread Method since this is the actual core and you want to make sure everything is covered with TIM (different to applying TIM on a CPU with IHS)

Now to the results:(open in new tab to get better resolution)



In the Excel you can see slight overclock of 1130/1680 with mv +13 and aux +13 in order to produce a little more heat then with normal 24/7 setting of 1120/1650 @ mv 0 and aux 0. The case Fan setting was so that all the fans were reduced in speed so that they are not loud. standing 2 meters away they were not audible (very silent).

The Grey line was with the old TIM. Heaven and Firestrike both produced 78°C @ 76% Fan and around 20°C ambient temp.
The second line is with new TIM keeping my custom fan curve. a drop of 3°C on each benchmark but check the ambient temp which was around 23°C. SO a DELTA of 6°C. Also the Fan only span at 69%.

So I forced a constant 76% on my fans to see the real difference (3rd line). I got a delta of 7°C in Heaven and a Delta of 9°C in Firestrike. considering measruement inaccuracy a lower temp of 6-9°C with changing the TIM is realistic.

I also noticed a lower VDDCin with the lower temps not sure what to make of this. And also the slight artifacting in Firestrike did not appear again, due to the lower temp? maybe, not sure.

Now I can put in my new i5-6600k with the asus hero VIII board to get a realistic go at overclocking thumb.gif

Hope this helps some people that plan on exchanging the TIM on their R9 390.
That's Choke actually. VRMs (the parts you want to cool) are on the right side along the chokes. VRAMs are actually referring to graphic card memory ICs.

I am tempted to see what they did to my MSI but my temps are great so I must restrain myself from messing with it! I never really liked the spread method as much as the pea/BB dab, but that's another debate entirely.

Yeah my temps were alright, but I thought "hey if I can get another 6°C improvement with 30 min work... why not" biggrin.gif And you are right, you'd think they would put more effort into these heatpipes, but hey, also on the new skylake CPU you can get 10°C or more improvement on delliding and changing the TIM. But for the everyday user, it would probably not make a difference.

I would either go with spreading or even the star pattern method that EK suggests on their waterblocks.

Like you said Dundundata, that is an entirely different debate rolleyes.gif But like tolis 626 said: on IHS fo the CPU i also use the pea method since you already a have a cooler on the CPU die, but on the GPU i opted for the spread method in order to make sure to have it all covered (it also depends what Thermal paste/Metal liquid you are using of course). the +-1 temp difference of perfect and near perfect spread is ok for me. biggrin.gif

I just did that and it gives me a VID (or VDD?) of 1.275V. That seems kinda high, doesn't it? At stock clocks/voltages it only goes up to about 1.19V. Maybe 1.2V, but I don't think it ever goes that high.

Anyways, my ASIC is 74.9%. That's... quite good actually. I like it.

Voltage control chip is same as 290/X, all 3 290/X cards I've experienced do the same.

It's the first time I took notice and it bugged me quite a bit. More than it should actually. Since all is right, I don't care what the reading is, though. smile.gif

Many thanks wink.gif , I have not been following thread fully so you wouldn't mind stating do you have MSI 390 or 390X?

Why you're seeing VDDC lower than VID is a) software monitoring not accurate b) it droops c) a fair amount of voltage control is done depending on load I have seen if I run x benchmark I hit differing MAX VDDC than y benchmark.

ASIC rating = Leakage ID , I have read a few posts by the Stilt and the simple explanation is its opposite to what GPU-Z advise on ASIC rating.

Some informative posts by The Stilt:-

Those I think cover it well but there are also other posts by him with other golden nuggets of info smile.gif .

The only other thing I recall reading was he stated low leakage ID ASIC can sustain increase in higher voltage better (long term use) where as high leakage ID can't.

Why I asked for the test?

All factory roms operate using Electronic Variable Voltage (EVV) this mean based on some calcs depending on GPU properties a VID is set. The other thing that affects it is default GPU clock.

I found on my 290X that if I set ROM to have default GPU clock of 1000MHz I get VID 1.25v and as I set higher default GPU clock in ROM (not OC app) then it goes down. This is due to another calc which is going on, if you then set GPU voltage manually instead of EVV this effect stops.

I have not yet flashed a 390/X rom to my Vapor-X 290X due to custom PCB, so wanted to know if it is same with 390/X.

SO can someone with lower default clock 390/X than MSI 390/X like a Sapphire Nitro 390/X run same test and state ASIC quality?

Cheers.
