The 4800 series Driver, OCing, Cooling and Tweaking Thread

[trt740]

well what new with the 4870, have they finally utilized the entire core? I read it was running at 66% gpu useage under full load, any 3rd party overclocking yet and how about some true slider style fan control beside Asus, is there any yet? I really like this card but haven't kept up. What new with it?

Who told you that?

Everest

What version are you running? I don't get the VRM temps in my Everest...running the latest beta (I think)

 

[Kaleid]

People with aftermarket coolers, how have you cooled the VRM? mine gets really warm. up 120c with furmark. I have put small heat sinks on them and a 120 fan blowing at low speed, but ye still high :/

Three zalman ram sinks on the VRMs. Cooling AC S1 plus Nexus 120mm fan @ 7v (enough and quiet)
Max 60C on the VRMs (2nd one is the hottest)

Hello!
I have Sapphires HD4850 with quimonda 1.0ns rams. I hear that MSI HD4850 bios is with improved Powerplay. But what kind of memory modules it has? Is it safe to wlash with MSI bios? Thanks so much

 

[mmaker]

wow thats crazy, just 80c and 60c under full load. hows that possible... what everest you using. i use 4.50 1448 beta... dont see you get half my temp with different brand of heatsinks. something fissy going on.. i use OCZ copper heat sinks so should be good quality. U have 4870 or 4850 btw

4850 temps through GPU-Z 0.26

Here is my 4870 @stock but the cpu ram overclocked,It is not bad of a score i must say.

 

[pehoko]

CCC dont work for me on windows xp sp3 . Catalyst 8.7 , Gigabyte 4850 . I have installed all but , no way to run , 70C -idle 1465rpm , but no profiles to edit , on Vista x64 all works fine . Error 0x0000135 - need some advice , thanks .

780 core 1150 mem on 4850.CPU at 375X4.I really enjoyed using RBE and voltmod guide

I can't understand half of what you are saying... Try to type more legibly.

You cant read the VRM temp in GPU-Z afaik, if you mean gpu temp2 thats not VRM temp.


Anyways i put on the oem backplate together with accelero and that gave better VRM temp for sure. Not close to stable 80c temp though. The more runs you do in furmark and build up the temp in backplate the warmer it gets and thus VRM temp goes up. Guess the 120 fans cant chill it down good enough. A backplate looking more lika a traditional heatsink would be really nice i think.

mmaker, are you using IR thermometer to read temps? If you do, and because 99,9% of us don't have one (you're that 0,1% ) could you please provide a bit more info?
Like:
- picture with marked hotspots and temperatures on them
- temperatures you get with S1+heatsinks, S1+original backplate, more fans or different kinds/placing of those
- etc.

It would help others as well. You could start with a picture of hottest parts, and what exact temps did you have before and what you have now..

Anyway, your 120C is really hot.. According to this thread (here is very good translation!), where you can find measurments of same setup (backplate on, plus S1), and they state around 70-80C, even lower with higher powered 120mm fan, and that's after 30 minutes of Furmark. Perhaps something is not seated right on your card?

 

[erocker]

I'm not sure if Everest is reading the correct VRM temperatures either. With the stock cooler on my 4870 and the fan at 55% my VRM's never get above 67c using an infrared thermometer.

 

[mmaker]

nono im using everest like everyone else tested with all versions avaible, same high vrm temps.

i did however put my finger on the backside and on the heat sink and it was really hot.. but ye that doesnt really tell you the exact temp

 

[mat9v]

Well, you can always slap some memory cooler on the backplate to increase cooling surface

 

[mmaker]

VRM reach 79C using the stock OEM front plate. 80C using the stability test for 2 minutes

Hey any chance you can take a picture of your card? Want to see your cooling solution. And btw you have maxspeed on your fan that is cooling the VRMs? What size is that fan?

I noticed a big improvement in temps when turning the speed up on my 120s fan, not a big surprise though haha.

It's found on the OP. However, I do not recommend using furmark as a tool to use at this time. I am not sure if the everest temp readings are correct but I've tested a few games and my vrm temps are no were near 80C (found in Furmark). I've seen temps at 62C in a 31C ambient temp room (playing the game in window mode). But nothing higher then that. Also, a user name Dnottis says his card is now dead after using furmark a few times with temps as high as 126C on the VRM using aftermarket ramsinks, etc. However, didn't have any problems in games prior to using furmark.

Runs fine with Furmark and tops out at 63C with a 60% fan setting. Overclocked with AMD GPU Clock Tool.

So far, so good, but if I try to flash a BIOS, where I just changed the clocks to the ones above and the fan to start earlier with 60%, the card starts to flicker even on the desktop when not under load and then finally the whole PC reboots! I've saved the BIOS with GPU-Z 0.2.6 and actually have reflashed the saved BIOS and the card is fine again. I've flashed using WinFlash 2.0.12 without errors... but something must go wrong somewhere.

 

[sparks.nl]

Room temp: 26C
Card temp max: 60C
Fan settings: Custom fan settings
Clock: 850 / 1090
Voltage GPU: Default

GPU clock on 860MHz runs as well, I'll test it later. I will try to give more juice to it in a copple of weeks.

 

[LuxZg]

Nice score, but.. 60% is way too loud for me :O

I just got my card today, and I'm happy to confirm that it runs flawless on my Chieftec 450W PSU, even overclocked a bit through Overdrive (780/1090), and that's together with my CPU overclocked as well to 3.2GHz. So people with lower powered PSUs should be just fine! Specialy if you've got 450W Crosairs or other quality PSUs.

As for fan speeds, I've just tried 50%, while I was quick-testing clocks in Crysis, and boy it's loud! As soon as I get some time I'm moving my Accelero to this card.. even bought one more quiet 120mm fan for it

I'm off to change my system specs in sig/profile!

 

[Jadawin]

Well, my PC is well hidden under my desk and I've got 4 120mm fans running in my case and 2 92mm fans on my CPU cooler... and once my air conditioner starts to cool down my room I can't even hear the PC at all... I have to decide if I want to die by a heat stroke or if I prefer to become deaf.

I could run the fan on the 4870 with 40% as well, I get into high 70s then after a period of full load, but that wouldn't make my PC more quiet, so I tested how high I could go before I can hear the card. At 60% it was still less loud then the other fans and it keeps the whole system cooler as well.

 

[LuxZg]

LOL - ok, you win Jadawin I had a system like that before this one (it's my wife's now), and I was so surprised by cool&quiet effect of my new system that I've bought few silent fans for my old system as well You don't know what you're missing man

Though, when I open windows, loudest sounds are from cars passing by, and during day I could run 60% and probably wouldn't notice it at all
