4800 overclocking tool is available.
-
Tool works like a charm but it seems to override the "fan fix" i8n the CCC file. Fan is back to 24% and 81c idle temps @ 800 core - 1100 memory. I tried raising the an speed, changing profiles, nothing will change the fan speed now.

THX :up:
It works wonderful

i'v been try to use this since posted but i keep getting id error when opening amdtool?
thuoght maybe does not support cf but now single still same problem,it works with 4850 right?

re download and reinstall. if you are on vista, right click and run as administrator.

does not work for my 3870X2's

It should. describe the problem. if it says something like "failed to set clocks" then ignore it and click check clockspeed tab you will see it worked. the 3800's all did that.
-
:cool: Nice find indeed. Only problem is that my cad freezes due to lower fan rotation. :mad: Would a stock bios with a modified fan ramp do the trick? Or maybe the flashing one with the lookup table enabled for the fan speeds in the bios. Gonna try that l8r

-
big thanks again W1zzard
all fine and working with your link.
-
with 4850's if you go past 700 do you still have to kill overdrive using this OC tool?

Works now, guess I just needed a restart
-
Very useful tool for determining max OC, but I still prefer the BIOS flash to get different 2D/3D clocks. Excellent nonetheless. Thanks!
-
So what are the max OC numbers in stock voltage and cooling for the 4870?
You can get past 800MHz easily without voltmodding?
-
I have gotten 850, that seems to be the most on stock voltage, and it is plenty fast at those speeds.
-
Wow, 850 is very good. Is it totally stable, and how about temps/cooling ?
-
I got 840-850 too on my 4870 that's most likely the core limit without changing the voltage I put the mem at 1075 since ati auto tune got 1090 to be safe. It would be nice to have 900-1000 core with alittle volt bump. Then 280GTX can say bye bye
-
The tool works fine on my computer with Vista64 but I also have the fan override problem. The AMD tool causes me to lose my fan profile back to stock profile. Is there a workaround for this or is this a V64 problem?
-
Is there a way to get the overclock to save? So I don't have to set it every time.

W1zzard can you explain a problem I am having? Notice in the pic that I now have 3 different displayed speeds. In CCC I have the right clocks of 750/900. But CCC also shows 500/900 below. And then GPU-z has gone bonkers. This is after using the AMD tool for a bit. I didn't show it but it also says 750/900. Something may need to be reinstalled but I don't know what.
-
The 500/900 in CCC is your 2d clocks, run a 3d app and it will jump up to what you have it set to (750 in this case). Your GPU-Z has simply gone bonkers.

I figured that part out, been away from ATI too long I guess. I ran across another post describing it so I did as you said and I now see. So, should I just re-download GPU-z again or does it have a cahe file to clear?
-
this tool is impressing me more more as I use it, if you go to high it will just stop the display and thats it no screwing anything up. I have gotten 882/1002 on all 4 of my gpu's with my 2Xhd3870's and thats pretty impressive for me, considering that before this I would only get 855 and 955

Looks like you are using the 8.7 betas which aren't supported by GPU-Z yet.

I can get 840/850 stable, but I am sticking with 840core and 1100 mem, it needs more voltage to go any higher, I get no artifacts in games, and it plays perfect for hours, and hasn't crashed on me once. so I have flashed the card at those speed with fan speed of 38% and it idles at 50c and under load the fan spins at around 40-42% and the temps actually stay in the 59-60c range, noice is not an issue for me because I have AC running in my room.
-
I get almost exactly the same clocks, 840/1100 is stable for hours of gameplay with no problems :D
-
Hmm, what kind of clocks are you guys getting on a 4850 with the stock voltages?
I swear mine was not stable at 700/1100 in CCC, but on second thought there is the chance my CPU was what was giving me crashes.
-
well, after days of testing and trying to get my core higher than my initial 790 with rbe and this amd tool i have had no success...
in fact... i havnt been able to run furmark at anything above 740 since the first evening in which i benched @ 790-1100 all night...
it turns out my ddr5 has degraded running at those speeds. my core actually has no problem running higher... my memory is now max'd out @1040...
this i can live with... phew i thought i was going to have to return these cards...
be carefull how high you run your ddr-5 for... you may just be damaging it...
-
I think to be safe I would run at 800/1000 for a few weeks to see how it handles. This seems to be very capable without damaging either core or memory, can run at stock volts and guaranteed, as well as keep noise and heat under control. If that did well I would then slowly raise up to 820/1050, 840/1100 etc. I think a sudden jump in clocks on both core and memory with no 24/7 real world testing is giving false excitement. The good thing is that summer is now upon us for most parts in the world, so if your card can keep up in this heat it should do well all year around from now on.
-
I had alot of trouble overclocking the ram even 25mhz with overdrive I would get screen flashes and my performance would drop. With this tool I haven't had any issue, I just need a volt mod to get over the 840/850 barrier.
-
The posts would be more informative if people would also mention which brand they have.
-
NKD and HALO what vgpu are you using for 840 core? I would really love to go higher than 725.

Well DUHH on me. I never thought of that and yes you are right. I mey just go back to the 8.6's though. I lost a couple of hundred 3dMarks with the beta's.

I have the same issue, and that's 'cause of 8.7beta.

Can anyone confirm this/any tool will work with x64 Vista? Or do these utils all use kernel mode drivers?
-
Works fine with Vista x64, no need for me to run it as administrator even.

I think we both have hd 4870, well I can speak for myself altleast lol, everything is at stock and the fan is at 38%, my card idles at 48c and load at 58-59c, even with crysis, however my room is air conditioned.

Stock vcore, this is a 4870.
-
haha nice that explains it, sorry for the brain fart.
-
Has anyone got this blasted fan issue figured out when you use this tool? Or did I just overlook it somewhere. Every time I try to set a clock with it, my fan speed drops to either 5% or 0%. Not cool.
Furthermore, while I'm thinking about it, the 4870 only differs from the 4850 in terms of GDDR5 and a beefy cooler for the higher core speeds, right? Or is there something else inside the core?

Vcore
-
But physically they are the same? If thats the case.. I may well invest in that larger cooler, slap my own fan on it and let the clocks rip. I'm liking this 850+ core stuff.
-
Which card should I get if I don't want to change Vcore, but will use CCC Overdrive, on stock cooler (don't mind setting fan higher), at 1680x1050 resolution? I'm interested in Crysis: Warhead, Fallout 3, The Witcher Enhanced Edition, STALKER Clear Skies and Farcry 2 for later this year. While the 4850 seems great, I'm worried that it won't be quite enough to hit smooth framerate since I'm seeing it takes a 4870 to run Crysis well on High at this resolution.
I'm probably not buying until August or September anyways, since thats when STALKER Clear Skies and The Witcher Enhanced Edition will be out.

It overrides the CCC fan profile, but not the bios one. If you flash the bios to stock speeds but with a better fan profile ( I used the transfer function between 45 and 90 ) and maybe some extra vcore once you start hitting the limit, this OC tool doesn't change the fan settings.

Better voltage circuitry perhaps?

It don't take much to hit the limit on the 4850s. I get artifacts upwards of ~660. That is with the card running about 66c or so under load, so I don't think it's too terribly hot in that respect. I will end up flashing the bios here shortly to see what I can end up getting. What was the safe voltage range again for core and memory?
-
if you dl the msi bios, it is the only one that when you open shows a lookup table for fan control(as an option). select it in rbe , save the bios, flash it and this way you get a decent fan speed with rotation as fallows: 31% at 60, 42-70, 52-80degrees celcius. Its the best I can do so far. I alse used 1.158v for the stock 3d clocks in that bios and I can safely do 750core with 1.2v(dmm). :up:

Consider yourself lucky then. For the hell of it, I tweaked the fan speeds to my liking, slapped a few heatsinks on the mosfets mentioned in page 18 of the 4800 series overclocking thread in the X-Overclocking subforum and I still can't even break 720 stable in RTHDRILB with the voltages at 1.2. Granted I can't quite confirm it's at 1.2 seeing as how my dmm needs a new battery, but I do notice that I can clock slightly higher and the temps correlate.
Right now it's running said demo at 714/1000 and finally seems stable. Fan is at 70% with the core temp at ~72c.
I don't see it being worth it at this point. Maybe I got a moot clocking card. Unless I'm drastically overlooking something here. The card is a Sapphire, if it means anything.

Yeah, I have flashed and re-flashed with different voltages and my Visiontek 4850 seems to top out around 700 anyway so I just use CCC Overdrive and keep it at 700/1133, Oh, I did flash to the Asus BIOS that was floating around early on and the auto fan speed control with SmartDoctor workls nice... 1.16v, 700MHz is it for me... done tweaking for now until I get an aftermarket cooler....

Currently using 4850 in CF mode.
I can oc the first gpu using this tool but failed to oc the second gpu=(
Anyway to oc the second gpu as well via this oc tool?
TIA
-
@memory
i have the same problem. but i fix it ;) it seems that the second card is not really available for this tool after a fresh reboot.
my solution:
After fresh reboot i run a short 3dmark scene. 3dmark03 nature is good for 5 seconds.
then the oc tool work and let me oc the second card :D:D:D
http://pics.mwirths.de/pics/thumb/03_101485.jpg
http://pics.mwirths.de/pics/thumb/06_23227.JPG
i don´t know why the second card is not avaiable after a fresh reboot. any idea for this??

@webwilli,
Thks for the prompt reply. will try yr tricks tonight=)

Has anyone had a problem with FurMark and the 4870 cards w/hotfix 4800 series drivers?
I have my Sapphire WC with a MAZE 5 and RAM sinks. GPUZ claims my overall GPU temp is 36c @ idle with sensor temps of 36/70/36.
Can anyone confirm where GPU#2 is located?
-
I mounted a Accelero S1 Rev2 on my Sapphire HD 4850 with a 120mm 500RPM fan on it.
Idle temps are 50° and load temps are 70°-80°.
Somehow I can't get higher than 650MHz. Memory clock is at 1100Mhz. Everything beyond 650 core clock results in artifacts.
Why are you guys are all able to get that much better overclocking results?
Oh and what is temperatur #2 and #3 in GPU-Z?
-
I think your accelero isn't on there correctly... specially if a vf700 dropped temps noticeably.

Seconded.
Also, this has never crossed my mind before but does a squealing card indicate eventual hardware failure? Now that I think about it, every video card I ever had that wouldn't overclock for crap or gave me great difficulty would squeal under high load after the voltages were turned up. Last night while I was running rthdribl, You could basically hear how much load the card was under by listening to whatever it was squealing.
The few cards I did have that clocked like champs never uttered a peep.

No problems in furmark, running a 4870 at 840/1100 with the stock cooler and stock volts.

@ halo, are you running different drivers? Vista x64? It's the only benchmark it can not get through. Games wise, have only tried COD4, but 2+ hours no issue at stock. :shrug:

It will only let me overclock the second card, even if i bench for a while :(

Welp, my Sapphire 4870 just died. It was behaving very oddly from the beginning. Hopefully the RMA doesnt take too long. :shakes:
2 of the last 4 video cards I have owned in the past year have been RMA'd. What's going on these days?

that S1 isn't mounted correctly - i never see over 45c loaded on a single card and about 33c idle overclocked to 800 on core and 1.3v.
