4890 VRM temps, 100c+ = Black screen or Freeze Up, Thermal Shutdown

[ViRuS2k]

Thats right folks

Watch those VRM temps Carefully.
and get them cooled ASAP

currently my VRM temps are at 92c max load at 1.4v GPU at 980core/1100 *4600 Effective*

At those settings i was getting constant freezeing/blackscreens and lockups under FURMARK aswell as in games but not as bad or as fast as furmark.

once i figured out that my VRM temps where at 120c+ i relized WTF lol
so i slapped on some mini heatsinks and got a 120MM fan blowing across both cards in X Fire 2x4890s

Got the VRM temps down to low 90s and now what do ya know,
no more black screens or freezes or redlights turning on on the graphics cards

perticular D601 and D6201 Lights. meaning Thermal.

just a heads up and if anyone can tell me other ways to get even better vrm temps let me know.

I guess thats the design flaw OCCT has shown, what games make it happen?

Actually only thing that i have found out that makes it happen is furmark and OCCT hehe

but heavy crysis load got my VRMS to 100c+ but not anymore ;)

so watch those VRMs thats all im saying heh

[TiTON]

Just curious.. you say your VRM were hitting 100+ C. I do understand that you are on stock cooling and had voltage at 1.4v.

What was your fan speeds set to for the cards?

You added a 120mm fan to blow across the cards.. so these VRMS are on the back side?

yeah 120mm blowing across the back end of the cards.

also my fan speed is currently set to 85%
dont pay no tell to people that say the 4890s fans are loud,
yes granted they are loudish but no where near as loud as the 4870s fans are lol

[TiTON]

hmm.. thanks for the info. Where exaclty are the VRMS on the back side of the card. Are they by the LED lights? i want to make sure I put the fan at the right spot :)

[stangracin3]

if you werent shoving 1.4 volts through the card you wouldnt have this problem.

[GAR]

if you werent shoving 1.4 volts through the card you wouldnt have this problem.

It happens even with 1.31v i bet, regardless, those xfx cards are meant to run at 1.4v arent they?

:up: Thank you for posting

I don't know what this comment serves any good, just like the guy didn't know about!? duh!

After all, do you know what this forum names is?

[ViRuS2k]

1.4v on stock cooling is fine.

in crysis my temps at 85% are at 73c load.

VRMs are located where the sticker is on the back of the card.

;)

im trying to hit 1000core LOL

at 980 with 1.4v might need 1.45v for 1000core lol

[Andi64]

:confused:

85% on stock fan gives me 40°C idle, less than 55°C load at stock speed, stock vGPU.
I'm running now at 1.4V 1000/4400, 40% fan speed and it never goes beyond ~65°C. I don't test OCCT or Furmark.. just gaming.

With GTAIV, Crysis and FarCry2 my temps are between 60/65°C, I don't know about VRM temperature but I've never experienced a lock up or crash.

[Mescalamba]

100°C? Huh.. happy that they are made to survive 105°C? :) Or more?

Kinda.. disturbing, I was going to buy that.. hm.. :(

[largon]

Something is obviously wrong if VRMs are getting upto 120°C when using stock cooler. Bad contact or so.
I have nothing but the baseplate of the stock cooler on VRMs of my 4890, GPU is watercooled and in games VRMs never ever have gone above 80°C. Crysis makes VRM temp hover around 65-70°C.

edit:

Where did you slap those heatsinks? I thought you are using the HD4890 stock cooler?

[SNiiPE_DoGG]

yes granted they are loudish but no where near as loud as the 4870s fans are lol

its the same fan.


In general as largon says, you have bad sontact with your cooler - but these PWMs are rated at 125c operating temp so honestly 100c is no big deal.

why the heck your voltmodding for 24/7 on a stock cooler...? who knows :shrug:

[OC Nub]

I just got the Asus 4890, the one with the dual fans. GPUZ shows my VDDC temp at just over 100c in furmark. Also in smart doctor which I have never used before the overheat warning flashes constantly even while on my desktop idle. The rest of the temps look fine in GPUZ and even the VDDC is good until I start furmark. I know the simple answer is don't run furmark but it shouldn't get this hot. Should I RMA the card or do some of these cards just run hot? I have 2 HIS reference 4890's that get nowhere near this hot even with a small bump in voltage and running 1ghz.

They don't go into OVP until well over 125 deg C. As for the long term ramifications, heck if I know.... I'm not worried. (Heaven forbid I have to buy a new vid card :D )

[OC Nub]

After seeing a post about bad contact with the cooler, I checked the screws on the card, there are only 2 other than the 4 for the gpu. They were very loose, I tightened them up and the temp went down 30c in furmark, and no more overheating warning in smart doctor. Had just been approved for an RMA from newegg but canceled it. Now if ASUS could come out with an update for smart doctor to work in Windows7 I'd be extremely happy.

[Sliced Cheese]

My 4870 vrms hit 117*C after just 1 or 2 mins of furmark or occt, they are still rising but i chicken out at that point, waiting for the new thermalright sink to come out to cool those puppies, they are rated for 126 C though....
Damn digital vrms... thats what i get for cheaping out and getting a core only block i guess...:rolleyes:

an FC block isn't a huge improvement, you better keep the stock baseplate, remove the plastic shroud and gpu block and set the fan to 5% ;)

my FC block keeps the crd between 29°C and 32°C under full load but the VRMS rise up to 100°C :shakes:

what we need is a dedicated water block for the vrms (or FC blocks which cool them directly with water :( )


But as mentioned earlier: it's a PITA to get proper VRM contact and you may want to try and tighten or loosen the screws right besides the VRMs (i gained more than 20°C on my watercooler by untightening them (card bent slightly and the center vrms had bad contact)

Asus's tools don't work in Windows 7? :banana::banana::banana::banana:, I just received a TOP 4890, and specifically bought the more expensive Asus card for the manufacturer support of overvolting and overclocking!

[OC Nub]

I haven't been able to get it to work in Windows7 and can't fin a driver for 7. I had to use vista to try the voltage tool. Also Smart Doctor only allows 970 core :mad: at least with this card. It allows for up to 1.45v but thats kind of stupid because of the 970mhz limit. I didnt get the TOP card though just the EAH4890 so that may not be an issue for you.

[roadie]

Got my 4890 home and immediately fitted an Accelero S1 rev2. It took ages, and I had to perform a mod to the VRM cooler with a hacksaw, but think I got it on in the end. Any idea what idle (desktop) VRM temps should be? GPU-Z is reading 54 degrees on the VDDC slave for me.

[ownage]

Just got mine in. Surprised to see low VRM temps even with a high roomtemp. 1050mhz core on reference cooler, 1,5v, 85c on the VRM's.

[roadie]

Ok, the double sided thermal tape failed to hold its grip on the VRM sink to the VRMs, so its adhesion is now aided by a rubber band. I don't think this is necessarily a good idea, but I can't think of any other option right now. Anyone have an idea of the melting/failing temperature of a rubber band?

[OC Nub]

I would think high temps would start to melt the rubber band. Mine was hitting 108c in furmark, the card was so hot it was hard to keep my fingers on it.

Boil a rubber band... if it is still in one piece, you know :p
Anyways... the heat cycling thing with rubber(as I know, it can expand/contract quite a bit) may weaken/break it... a good zip tie here and there always works though :up:

[largon]

I never use rubber bands for any application where reliability is of any interest. Rubber bands degrade with time. And high temps seem to shorten their lifespan until they harden and fall to pieces.

[roadie]

The Thermalright VRM cooler can't come soon enough. I tried disposing of the rubber band to fit some zip ties, but because the VRMs are so small, the VRM heatsink was knocked out of balance and wasn't making good contact. The rubber band remains...

However, I have disposed of the Arctic Cooling Turbo Module for an Antec Tricool fan that is now zip tied to the Accelero. Desktop GPU temperature is now 6 degrees lower, as are the VRM temps. The noise level is actually lower too, as the Turbo Module had started to whine.

The Asus stuff seemed to work for me in Windows 7 with Catalyst 9.6. However, it messed up my desktop by killing the translucency effects and other things. It appeared in the same way as when VLC was running, which had something to do with DirectX being used. I've uninstalled the tools until there is proper support.

[YMAA]

The iandh sinks seem to be doing their job for my card. I haven't felt them yet to see how hot they are, but I'm running my XFX 4890 at 1GHz core on stock volts (Fuzion GFX2) and have yet to have a single crash or artifact in Crysis, Fallout 3, or WoW. Haven't tried Furmark yet, and I don't plan to for the time being. I got my goal of a stable 1GHz for 24/7 so I also have no plans to add more voltage...might clock higher, but nothing is set in stone yet.

When I get home today I'll touch the heatsinks and see how they're doing. My Black Pearl case has a 240mm rad at the top with both fans exhausting air...the air coming out is quite hot, which means the internal case temps are quite hot. Not sure how much of that is from the VRMs specifically though.

[nafets]

You need to download the latest GPU-Z (http://www.techpowerup.com/downloads/1379/TechPowerUp_GPU-Z_v0.3.4.html). It will tell you your actual VRM temps. You will need a fan over those VRM heatsinks if you do any overvolting.

[rpg711]

Yea my VRMs hit 100c on stock voltages... these things are HOT! I can't over volt at all or I see the vrms needlessly hit over 110C... are they even cooled by the reference cooler? 0.0

[ViRuS2k]

Got better cards now.

Instead of those dam XFX refrence cards i got 2x Asus Refrence cards

not only do they come with 3 years warantee and support overclocking in there warantee
they also have higher RPM fans

46xx rpm instead of 42xx rpm on the other refrence cards.

as you can see from this picture

VRMs are UBER COOL ;)
not only that but 71% fanspeed on these cards is 42xx rpm, that would be 100% fanspeed on the cards i had before XFX ect but not on these ASUS`s :)

temps look great aswell

25 minutes in Crysis warhead 1920x1200 2xaa 16xaf all setting on enthusiast

gameing is UBER SMOOTH AS HELL ;)

[rpg711]

Wow that's really cool for the vrms... how can you stand 70% fan speed? For me, 50% speeds(which is 3627rpm for my card) is already like having a tornado in my case, lol.

[ViRuS2k]

Headset ;) FTW, + there not that loud well not to me anyway, i use to have delta fans in my pc now those where what i would call loud lol

[GLENBOY]

can you post a pic up showing the h'sinks on back of card virus

[ViRuS2k]

can you post a pic up showing the h'sinks on back of card virus

There are no heatsinks on the back of my cards. ;)
as there is no memory chips on the back of 4890s.

Asus Refrence 4890s are the best 4890s you can buy.

i also have the ASUS EAH4890 with the dual fan cooler. the front fan was starting to whine so i got an Arctic Cooling Acellero S1 Rev.2 and zip-tied a 120x15mm fan on there. i was less than pleased with the quality of the stock thermal tape that came with the cooler so after much research and forum browsing, i ordered some Sekisui 5670 Thermal Tape. everywhere i have read only had good things to say about it. i got 8- 8"x1" strips on ebay shipped for $4.99. it should be arriving in the next few days. i'll test it out and let you know how it works

[metalop1g]

Mine sometimes give up for a second and the screen goes black (while folding @ stock everything). It usually happens 4-5 times and then I'm good for an hour
