So since there wasn't one of these I figured I would start it. :)
This is my first oc above 790 and I have great results. I have yet to receive my 2nd 4870 back from RMA so I will definitely have some more additions to this thread :D

Note: Others to post please follow this format, you do not have to use extreme preset but you get the picture
Could you tell me about the used softwares? I edited every clock with RBE but GPZ-U still show 750Hmz and my 3dMark score proof is. (Sapphire 4870) Should I uninstall CCC?
I just installed a GeCube 4870 and would also like to know what software to use to flash this baby.
My last bios flash was for the 8800gts 320.
Can't wait to oc this past 790
thanks
ps this is my first ati card ever, since the days of wolfenstien 3d
hopefully we wont have to wait long for some tools to come along ....used the gfx cooler fix atm to keep temps a bit lower
Hi Sniipe Dogg. Was all this on stock volts and stock cooler? Did you change thermal paste at all? What was fan speed at? Temps for idle/load at those settings?
As well, what did you do to thoroughly test the card for stability and artifacts? Have you tried higher? How does the card respond exactly when it becomes unstable?
Sorry for the myriad of questions, just very curious is all as I have my eyes set on this card. Thank you.
Here's mine so far, have gotten it running higher but the heat's high at 870/4500...

I don't own Vantage, so I can't post a bench of that. I have thoroughly tested the card for stability and whatnot, though. This is all on the stock cooler with no thermal paste change, 46-47c idle. Fan speed is at 37% for idle (at 49c it turns up), and 45% then, 54% at 55c, with the rest of the profile set to high temps that it doesn't reach. When it becomes unstable it just makes a kind of squarish artifact grid full-screen, for a split-second, and then the display goes black.
well, i'm really tempted to use rbe again but i dont want to have the card running with max volts in 2d.... its just not going to be healthy imo... i might be wrong....
as soon as we know which clocks effect which state, i'll be pushing my cards again....
by the way, if you've worked some of these out, let me know..... thanks in advance....
you must first flash to stock bios, the uncheck ati overdrive, then flash to the OC'ed clocks and you should be all setQuote:

pretty impressive.
So this is all at stock voltage? Has anyone measured the actual vGPU? It's listed as 1.263v in the BIOS.
i am borrowing a very accurate multimeter (6 decimal accuracy) on monday or tuesday so i will test then :)Quote:

Sorry, no 3Dmark results as I don't usually bother with those. I did see a nice jump in ingame framerates though, much more then I was expecting.
I don't think I will push it much more until 3rd party OC tools and waterblocks are available though.
I strongly suggest that you all test for artifacts with ATI tool, this ram is only specced to run at 4ghz. When I run at 1050 or even 1020 I get artifacts and if your card is in fact artifacting you are slowly killing the RAM. now I am back at 1000 and I get no artifacts after 45 mins of artifact test.
I get no artifacts on the ram at 1100 or 4400, whatever you wanna call it, I teste with ati tool for about 15 mins and no errors, I believe it is the heat that might give you artifacts on at those speeds, but this ram seems to be perfectly capable of 4400, I set my fan speed at 37% and it idles at 49-50c and never breaks 62c under load. I have it running at 840/1100 with the bios flash and fan speed edited. at 850 I did get artifacts in crysis only at very high, so now at 840 I do not get any artifacts. here is a vantage screenshot with my gpu at 840/1100, and q9450 at 3680mhz.

lol I tried the medusa demo crack and it actually worked but half way through I started getting glitches.
...waterblocks are available for a long long time, since you can use the same as for the x19xx and HD38xx series. I find the best performance/value ist the Zalman ZM-GWB3 in combination with MX-2 thermal paste.Quote:

I just bumped core to 830 on stock volts and it's running flawlessly, furmark included :D
5 seconds into furmark the pc crashes..... but it was fine the first night when we used the 64k bios accidently....
i benchmark as its what i enjoy doing... these cards are going to have to go back if everyone else is fine on stock voltage....
is this accurate... is everyone else just using stock voltage... and could you please say what stock voltage is.... stock on your card might be differant...
on another forum someone is only able to go to 800mhz core so you are not alone
then these cards have weak cores... its unacceptible that a 4850 can clock higher with same core...
? You are on stock volts, I'm on 1.35v and under water.
how do you explain other peoples success with these clocks volts and 4870's....
could be luck of the draw, could be heat, perhaps they have added some voltage in the bios.
thats what i'm asking m8... please let someone answer who owns the card... instead of blabbering on about your 4850....
I was wondering how are you guys getting the amd gpu clock tool to load up, I right click on it and " run as administrator" option does not show up. any ideas?
tuned
got it. had to browse to the programfile/folder.
Cain, try editing w1zzard's fixed bios with RBE and setting the fan pwm to "recommended". Maybe your card is hot/unstable? It could just be luck of the draw like processors (pretty likely).
http://service.futuremark.com/compare?3dmv=218009

Unfortunately I think I've reached the limit for my q6600 in 3dmark, even a 3.68 ghz q9450 beats my cpu :(
@NKD. what OS are you on 32-bit or 64?
the cards wont even work at 790/780/760mhz... 755 and they are stable... the gddr5 is happy at 1100mhz... so i'm going to send these back tommorow... something is definatly wrong with these cards...
Before that, could you tell us which core rev you got.Quote:

i'm sure it just said manufactured in taiwan... there was no rev info on the core.... where would that info be on the packaging...
edit.. i took 5 pics of the core and they are all blurred.... typical...
Increase the lighting and it should be easier to take non-blurry shots.
I should amend my above statement about water blocks - I wouldn't be against using a GPU block if D-Tek or others released a unisink style ram cooler.
Works fine for me without even hitting to run as admin on Vista 64.Quote:

That's with 4400 RAM. 840 core performs well but 856 is a HUGE jump over it... also takes a lot less fan speed though at 840/4400. I think the RBE bios voltage does work though because changing it is affecting my stability/heat results... heat is the major issue :(.
I can't confirm by how much, but I am now sure that changing the voltate in RBE does effect the actual voltage.
I increased it to 1.3v (slowly) and I am now artifact free at 790. 800 has errors occasionally, before there were tons of errors.
I wonder what the limit is for bios adjustment as I don't have a DMM...
turned out to be the gddr5 which had degraded... with the mem @1040 the core will bench at 840mhz....
what are safe voltages for this card
and where are points to test with DMM, if someone has a pic showing this
thanks
how do you set the 2d and 3d clocks with the gpu clock tool? It's greyed out for me, which makes no sense, why bother putting in the option if you can't use it?
Has anyone got the AMD tool to work with crossfire, i just get "set clocks failed!"
works fine with crossfire disabled, but after you have set your clocks crossfire is greyed out so then cant be turned on :confused:
I am running vista 32bit with 3gb of ram, and also I have the 8.7 beta drivers running, they give a good boost, they gave me around 400 points, I have ran vantage a few times with the beta drivers, and I always got different score, sometimes 10428, sometimes 10525 and I even got 10638 or something, it seems like the driver is not really optimized that much, but it is still better than the old driver.Quote:

today i had a quick play with new HIS 4870. I changed fan value so it kicks in a little latter as was a bit loud at IDLE.
Here quick test straight at 840/1100 out the box
http://img357.imageshack.us/img357/6...thfanmotj8.jpg
How can change fan speed and overclock over 790/1100? If i set fan with CCC profile then AMD GPU toold override it!
try running furmark to test stability instead of atitool.... you know your clocks are stable if it can run furmark.... also enjoy having your ddr5 @ 1100 as it wont last....
Since you have experienced degrading GDDR5, what would you recommend as a safe and stable 24/7 usage on the ram for an overclock?
Have two questions about the HD4870, could anyone answer them please :)
× Does the HD4870 also have some sort of 2D/IDLE Power-saving mode?
× Which brand should i buy? HIS, MSI-OC or Sapphire?
Does every brand of HD4870 have the same cooler and voltage? I am considering the upcoming Asus one, but I was wondering how the ones already on the market differ, since they vary in price.
1100mh on ram crashes in furmark almost 20 seconds in. I found 1065-75 memo and 830 core is my max on stock voltages, while still staying nice and cool@ 55C load.
If i could find my stupid red lead for my DMM i could put those on the points that Wizzard had pointed out to test voltage. I want to play with volts in RBE, but need to find that darn fangled lead..ohwell maybe this weekend after i tear through my closet.
does RBE even adjust the voltages well? or would a pencil be needed
Thanks for sharing. To play safe I think I would use 820/1050 as it seems most cards should be able to do this with ease at 31%+ fan speed. I hope at those speeds it demolishes my currently overclocked 8800 Ultra.
So since your's degraded, so will everyone else's..... /sarcasm offQuote:

I was running at 1050 and i even went down to 1000, the ramdacs are rated for 4 ghz only by spec. I will be trying the MVDDC and MVDDQ pencil voltmods for the ram as soo as I confirm that my voltmod was successful (dont have the water loop together yet so I can't plug the volt modded card in to the board)Quote:

I have a iron, might get confident with it soon.

@ NKD thanks for letting me know, this explains why you have a higher vantage score than me even though i am at higher GFX and CPU clocks.
It's the operating system, stupid. :D

on another note, i just got shipped notification on my second 4870from RMA :woot::woot:
great, thanks for the reply. 820/1000 seems ok to shoot for.
Hi.
I can just about manage 800/1050 here, infact 790/1050 seems my best bet. Should I be able to get it higher with more voltage?
I dont want to break it!!!
been away for a couple of days... i would suggest that 4870 owners run there cards gddr5 at 1040mhz... i know for certain that these speeds are fine as both of my cards respond indentically....
my cards are from HIS...
we should be able to unlock the cores with the new oc bios from diamond, i'm just looking forward to this now....
@willhub... lower your gddr5 to 1000 and try to oc your core again....
@snipedog... i would love to know how high your clocks will go with FurMark...
I did try 1000, did not help.Quote:

some pretty nice modding you've done there :woot:

The stock cooler isnt bad at all, my idles are 38c now and load is under 50 after just putting MX-2 on the chip. Wonder how it will scale on air with some extra voltage. Did you run test with increased voltage on air to check temps. should not be a huge difference on air between water
no modQuote:

Dont know if stable yet but ran a benchmark at 810/900 and it compleated 3 loops of crysis, same as 820/900.
Ok compleated 10 loops of crysis benchmark at 820/900, 825 did not even last 10 seconds so it needs more voltage, wth ram overclock max is 790/1050.
I reflashed my Bios with Winflash to change the fan speed.(I got in trouble last time I did this). No problems today and I used the look up table option so the speed would ramp up as temps increase.
Mostly the temps stayed in the 60's when loaded and the fan was running at 37 percent. I left the voltage alone.
First I tried raising the core clock and I got to 885 and the system locked. I had tested at 875/900 for about 5 minutes and didn't see any artifacts just before raising it to 885 and crashing.
Next I wanted to see how far the memory would go so I left the GPU at 800 and started ramping up the memory. I was surprised at how well this card clocks especially after initial reports on the 4870 indicated that it wouldn't be a good overclocker. This time the memory went to 1210 before my sceen started breaking apart. I ran at 800/1200 loaded for about 5 minutes with no visible artifacts.
I think I can easily run at 850/1150. I'm going to load Crysis on this machine and see how it does. This machine is on a DFI motherboard with an Opty 185 at 2.75 Ghz. I had to RMA my P5e Motherboard and won't be able to test with my q9450 until I get a new motherboard. I have a 790i machine but I dont want to load ATI drivers on that machine.
It seems like everything works easier with XP than V64 so maybe I can get my Bios the way I want it with XP before I put the card back on the P5e. I am still just amazed at how fast this card will clock. It is tempting to add a little voltage, but I've already had one scare with this card and would like to actually play a few games with it. I've mostly just been testing and fixing so far.
so far this is my best run

Farcas is that the max you can get without voltmod?
Can't wait to see what you can get when you voltmod ;)
That's the best so far I believe and you seem to have alot more room on temps.
My highest OC so far (using AC Accelero S1 with fans + no Vmod):

For some strange reason I get a better score with mem @ 1100:

Okay, one question: Is it possible to alter fan speeds without BIOS flashing if you try to OC above 790MHz (need overdrive off) ?
Not as of yet...unless you just pull the RPM control wire from the fan header, making it run at 100% all the time. You need overdrive on to do the profile-based fan fix.Quote:

it is possible! I use AMD GPU CLOCK TOOL to set clock speeds and then load up modified ccc profile with the desired fanspeed. Before you do this you should modify your profile file by delete the part on top of the list whicj contains the stock speeds ( 750 900 thingy on 4870. works wonders Though i cant get my card past 830/1050 without getting some artifeacts in atitool in about 4/5 minutes. It also doesnt help if i set fanspeed to 70%.
ps are somewhere @ 50-60 @ load on 70%
Would it help to get a HR-03 GT?
That's the most straightforward solution I've ever seen :D
So wait, things I have to do in order:
1. Modify the profile by deleting the clock speed part of the file
2. Modify clocks with AMD GPU CLOCK
3. Load up the profile?
I'll give it a go and inform you of the results, thanks!
Okay, I did what you said and after I loaded up the profile my clocks remained at 800MHz but the fanspeed failed to match the one in the profile I loaded. What am I doing wrong?
ok now the full manual :P
1. make a ccc profile
2. edit the profile with the usual fan hack
3. remove the default clockspeed thingy
4. save it
5. start AMD tool and set the clockspeed you want
6. CLOSE AMD TOOL AS IT DISABLES CCC!
7. then load up CCC profile with fanspeed and without stock speed
8. Joy!
for those who want it the easy way. Here is the part from my profile section in the XML file. with 30% fanspeed and removed stock speeds. For 4870

I oc'ed both cards to 820/1050 (no voltage needed) with AMD GPU Tool to see what gains i would get in 3dmark06. To my surprise, i gained only ~200points or so. Is this normal?
I didn't do the profile thingy btw, but gpu-z reported the 820/1050 freq's correctly for both cards.
Does powerplay still work using this method? Thanks by the way!:up:Quote:

If I set GPU speed to over 790/1100 and try to go back to CCC, the option to set clocks and fan is now locked. The application does not want to run when the card is clocked higher than it allows.
I just flashed the BIOS and put in a custom fan profile. You can then set the clock speed to whatever you want and not even use CCC. In fact I turn off CCC now.
I've been able to clock my card pretty high when just testing with ATI tool(around 870/1250), but about the best I can use in games without some sort or problem is 820/1175. If I go over 820 gpu, I get a crash or freeze after some period of time. If I go to 1185 mem, then I get artifacts. I haven't tested with FurMark which will stress the card more than Crisis or Mass Effect, but I have read where it FurMark has killed some cards. As long as I can play games without error, I really don't care.
Did exactly as you said. Didn't work.:shrug: Sure you didn't miss anything? Could you possibly post a pic of it working?Quote:
