*** Official Radeon HD5800 Series Overclocking Thread ***

come on MONSTRU lets see some overvolted overclock action on the 5850, its been 14 hours :D :D, and we want pics :yepp:, you know computer guys have no patience,thanks mate

http://www.abload.de/thumb/frumarkz0ih.jpg

burnmark^^

worst program i ever seen xD > 100°C vrm after 1 min xD

yeh nothing comes close to heating them up like furmark in reality

hate this program xD

its good if you want to bork your cards, i saw a thread somewhere and the guy said i did 20 loops of furmark with card overvolted, then my card died, what he expect, i think its ok as long as you monitor the temps like you did in the above screenshots

haha, need a VRM waterblock... lol

http://www.abload.de/thumb/2minfurmarkn67g.jpg

2 min.. now thats enuff artificial stability for me xD

vrm waterblock would be nice for furmark indeed xD

for normal games i dont need, in crysis, the vrm's get only up to 75°C

whoever invented this tool wanted piss off the cards manufacturers xD

yeh thats some heat , when i had my 3 x 4890s in it would heat the whole room , no need for cental heating

lolz :)

http://www.abload.de/thumb/bench31zo.jpg

crysis original 64bit dx10 very high 1680x1050 4xAA 16xAF MSAAA

never thought i'd get crysis that playable with this card^^

yeh crysis seems to fetch any card to its knees generally

I want a WHQL approved driver soon... :(

Little overclock review for a friends blog. Originally in spanish,
http://translate.google.es/translate...-y-escalado%2F

I think is time to play with crossfire :yepp:

Does ATIFlash 3.75 work on vista 64? (says OS not supported) Or did i miss a work around? :confused:

Great article, and good summary - I like how it compares all the averages. nice work! :up:
http://blog.pccomponentes.com/wp-con...EDIATOTAL1.jpg

Thanks ;). I will make another one about crossfire scalability if i receive my second 5870 in time

Saw the SS' from Oese and decided to see what it was like on mine. I thought his VRM temps were a tad high...

http://webpages.charter.net/darkdark...urn%20Test.jpg
http://webpages.charter.net/darkdark...20Test%202.jpg

I was wanting to put my MCW-60's on these cards, but after seeing how hot the VRM's get, I think I'll wait for a FC block.

yeah the vrms actually get hot using those passive heatsinks..

thx for posting a comparison :))

ahh EK's FC waterblock cools the VRMs properly :D

For what it is worth, my 4870x2 vrams would load much much higher (try 100-115C ; that was at stock and gaming, not furmark) than these 5870s ( hell you are at 1Ghz overvolted and still doing under 90C....) Assuming the vrams on these are of the same quality, I don't see what the big deal is.

I'm happy enough with the CCC limits ( yes I know that is crazy talk ) being the default thermals and noise are respectable for me ( compared to my X2 ) Who knows, I might break out my rad again down the road and have some fun though:p: I probably would get it a FC block though ( I know gpu only blocks result in lowest gpu temps but honestly its not like a few C higher on the core for the benefit of the rest of the pcb is going to matter ; only negative is the fact they aren't easily reusable )

the card at the ek test is undervolted to 1.125v and on stock clocks, but whatever, very nice temps :)

I'm not sure if you can say undervolted, because my card has 1.125V stock as well! This might be only a feature for Sapphire cards or newer batches are already better yelding and they lowered vGPU.

If you want lower power consumption try my BIOS from TPU and see for yourself :)

EDIT: This also can be a reason why some of the reviews are claiming that HD5870 is louder than HD4870 and others are saying opposite.

Got my 5850.
His brand.
run 3d vantage at 850/900 15k.
cpu i7 4cores at 3.3ghz.

still need a updated bios (asus) for flashing the card.
using msi afterburner/amd gpu tool.

as far a nice upgrade.
Company of heroes.
1920x1200 dx10 all maxed even model detail 0xAA.
5850 725/900
58 min fps.
115 average fps
231 max fps.

4870 512mb 790/900 before same settings.
1920x1200 max all model detail 0xAA
37 min fps
78 average fps
149 max fps

The difference at 8XAA was around 50/40/50 more fps to the 5850 advantage.
At 0xAA overclocked 850 on core added the following increases fps (58 to 71 min fps) (115 to 127fps average) 231 to 254 max fps)
Same in everything else, a 125mhz increase.

Pleased :)

That min fps got a huge bump. To much increase for only 125 MHz that cant be right. If i'm not mistaking COH had the same engine as DOW II. I use DOW II for benshes i have seen the fps variate a lot. What i do is do 3-5 runs and add all min fps numbers and divide it by the number of runs. + if i see that the min fps is lower then normal i will redo that run.

thanks for sharing flopper

yea, it will vary, not doing science here.
same conditions apply, same hardware, same settings, one run.
Wasnt interested in nitpicking exactly as this I just do for fun.
Dont like to benchmark ;)

Really nice HD5850 OC Flopper!

This is a card to buy if you want to save over $100! I must admit that I'm not even OCing my HD5870 for gaming at 1920x1200! I only oced my card for fun and few quick benches!
The only game which might need OC is Crysis, but I will play it again after finishing Heroes of Might and Magic V I'm playing now ...

Actually, it does the opposite! We scale the voltage based on leakage, so the higher leakage parts use lower voltage and the lower leakage parts use a higher voltage - what this is does narrow the entire TDP range of the product.

Everything is qualified at worst case anyway; all the TDP calcs and the fan settings are completed on the wors case for the product range.

I think 5870 Cypress XT's can require different 3D voltages to keep stability at 850mhz, and that this is why we're seeing stock volts anywhere from 1.1v to 1.17v for 5870s.

From Dave Baumann response I've got at Beyond3d it looks like overclockers should look for cards with 1.125V stock 3D because they will clock better albeit using more power, just like AMD Phenom II TWKR edition!

i can change fan ? always 1000 rpm/25 % ??

That would explain a lot.

I've actually had issues at 900 at stock volts in GTA ( hard lock ; funny thing is Crysis doesn't lol ) I am not sure how high I can get without upping the voltage but I am content with the card as is now all around so I won't press the matter anytime soon.

My XFX has a bios with 3d voltage of 1.1625 by the way. I might try manually lowering to see how low it scales at stock core clock out of curiosity.

900 / 1300 :down:

http://i34.tinypic.com/i58wee.jpg

Yes, it's basically being confirmed by Dave, "We scale the voltage". Aka, "we bin the chips and assign 3D voltages accordingly". It's similar to VIDs - not like every Q6600 clocks the same on the same Vcore. Really, you want a 5870 that runs VERY cool while clocking upwards of 950-1000mhz on a stock 3D voltage of ~1.12-1.13v. You might have to sample 20 or 30 different boards until you find one like that! :p Heres to the guys that have a 3D volt of 1.125 in bios and can go above 950mhz with it.:toast:

Flopper, what volts for 850mhz on your HIS 5850?

My asus has 1,125v in 3D mode :cheer2:

so i have bad card 1.164v stock

I wouldn't say bad, it just needs more overvolting for higher clocks thus higher fan speed / better cooling. I can get 1ghz core but the voltage increase isn't worth the heat or noise ( performance doesn't justify it ) so I'm sticking with 900 tops. I still haven't tried reducing vcore for 850 to see if mine really does need 1.162 or not. XFX may have done them in batches or merely just decided to set all units this high for the sake of stability. Anyone with an XFX 5870 have a lower default 3D voltage than 1.162?

If anything between the 5850 having disabled shader clusters and them binning voltages, my guess is yields aren't that great. I'm really getting the feeling now that the X2 will more likely run slightly north of 5850 clocks due to both power and yield reasons( although still 1600sp)

And that is a nice score Gaul, you still got 100gpu score than me at same gpu clocks so that E8400 is holding up very nicely. Screw vantages cpu score, its a biased piece of crap.

yeah think so too, it seems that some cards vendors just got all cards out at 1.162v, others maybe binned or idk...

dunno if 1.3v is too much overvoltage?

950@1.2v is my sweetspot, probably 900@1.125v i could try.. but 1ghz core is an achievement :) so i test it for long term stability now i decided :)

now thats more like it you're lucky to have one so soon there are none anywhere and no results on hwbot, get a score up you'll be no.1 in the world with a 5850 on hwbot :)
http://hwbot.org/hardware/videocard/radeon_hd_5850

also you want ht enabled for vantage thats why you cpu score is low, the cpu score should be well over 20000 if you are on an i7, with ht on i reckon thats about a 16.5k score

just saw this post from zbogorgon. he's using an Ek full cover waterblock at 1120mhz / 1.36v. Is card is also default 850 / 1.125v. :O

Pretty impressive but man that is some voltage. Water only territory indeed. 1.36 idle for 200x20 scares me though hehe. I'm assuming cpu is on water as well.

Looks like the EKs will do a fine job.

Great score :clap:

Here is a run on a AMD platform w/XFX5870@900/1300@1.16v.
http://img225.imageshack.us/img225/7...enshot011g.png
Havent had any heat issues or lock-up's during gaming.
Wish I got the ASUS instead, didnt feel like waiting lol.

Is there any point in going asus if you can just flash any card afterwards? Do they have nicer 3d voltage? They are like 30$ more expensive in my country just wonder if those 30$ are well spent

I guess not really MechOz, all the 5870's were the same price when i bought my XFX. I kept getting errors with Atiflash 3.75, but i try again later.

try -fs as oese recommended

@ ALL = ANYONE has same trouble with me ?.....i can't use manual FAN SETTING , no matter on WIN 7 64 bit ( 8.66 RC6 ), even XP 32 bit ( cd installer )....

with 2 OS, i can push more than 20%, even i push to 100%, its still 20 %, cek THE RPM........THANX ALL

SEE cat say 100% but GPUZ shows only 950 rpm and STILL 20 % FAN SPEED...

http://i33.tinypic.com/bg4ry8.jpg

WELL IT IS DEFACT ???? 5870 ? or flash to ASUS BIOS will HELP ?? :shrug:

anyone plzzzz need advice here....

watercooled, 900/1300 now. was 900/1200 in the screenshot.

Are you able to do an extreme preset run? If not could you do a custom extreme run at your displays highest resolution? I want to see how processor bottlenecked the performance preset on these cards is.

I am curious as there is roughly a 5000 gpu score discrepancy between your Phenom II and my I7. That just seems like way too large of a gap to me :shrug:

@ dnottis: nice!!

i just wonder why i get way higher frames, more power consumption and higher temps when using same settings... could you try renaming the .exe to see if its throttled?

Dunno, Im using the MSI beta 91.0 RC7 driver. I definitely dont have any framerate issues. Are you using AA in Furmark? I think I was using 4x.

http://img19.imageshack.us/img19/553...09105508am.jpg

seems the card I use dont work with the afterburner properly, the voltage dont stick,
I belived I was upping the voltage but after the night and tiredness was cured with sleep,
I check the window on the msi hardware monitor and the voltage is 1.087 no matter what I try to adjust using msi afterburner.
(any ideas?)

so, the card does, 850mhz core on 1.087v.

950 failed @ stock volts in Vantage. Havent played with voltage yet as Im not sure AfterBurner is really applying voltage. Dont really want to flash the card, its really fast in games right now and I had multiple 4870s die on me. I'm just enjoying gaming right now and the low temps. The PCB doesnt even get warm, VRMs either. This thing is running so cool. Maxed CCC 900/1300 for now, games are screaming!

uisng afterburner solo, voltage apply works, with amd gpu tool, buggs out.

i wonder if its because of the ccc low max clocks , come on lets get an asustop bios or at least one with much higher ccc limits

waitin for asus or someone elses unlocked 5850 bios ;)

Seems so unfair that they are using I9 to break records before the cpu is released :S

Anyone know how much the i9 is going to be?

WOWWWWWWWWWWWW!!!
Really cant wait to get my 5850 and start the OC marathon for this thing!!!!!!!!!!!!!!!
But i have to wait for a week at least till it hits the selves here....
I ll put a MUSASHI on it so be ready for some serious clocks soon!!!!:D:D:D

Hi

HIS5870 flashed with modified bios
Using msi Afterbunrner
Clocks
gpu 925
men 1250
V 1.29
3D mark Vantage 18133
water cooling next on vid card

thanks for posting up beast sounds a lot of volts for 925 core , really 1.29 is only really needed for 1000ish going off what other people have used,unless yours just needs higher volts as all these gpu's seem to vary, have your tried lower volts or a higher gpu clock

im still waiting for a 5850 to come in stock at egg.

so let me get this straight, with afterburner you can change voltage via software?

interesting.

DEF BIOS

5870 @ 975/1250

http://i34.tinypic.com/2lsy0x4.jpg

Anyone having problems with 2D voltages being upped to 1.6ish when using MSI Afterburner?

I had to uninstall the damn thing. Has to be a program bug.

This guy Jonny Manc has exactly the same problem: http://forums.guru3d.com/showthread.php?t=306019

:confused:

Don't worry the card has overvoltage protection, you won't kill if it says its 1.6v, its not.

I hope you're sure about that, else I may have voided mine's warranty or something like that... the VRM temp was in the upper 70's :(

There is, same as the 4870x2. Tried all I could to get that over 1.37 volts and it couldn't be done via software.

Maybe someone with a DMM and the back off the card will give the actual value, but its there.

And, loco just did 1200mhz core / 1250mhz mem on Tri-Fire using 1.375v thru afterburner (LN2 cooled). He says that > 1.375v doesn't give him any higher mhz, so he thinks that OCP must exist somewhere around 1.375v.

With the ATI Radeon HD 5800 series we’ve implemented a hardware-level overvolt protection scheme where a signal from the regulators can be fed into the GPU directly and the GPU can take action if the regulators indicate they are operating out of their specification. In the unlikely event that such a scenario happens, rather than the board turning off, the GPU is designed to clock down to get the regulators back into a normal operating zone and then clock back up when they have done so.

---

Anyone else think that Ati might have initially deperfomanced the 5 series at launch on purpose to seemingly show lower performance numbers. Then after a month or two there will be some new driver that increases the performance 20-30% across the board. Maybe they did this to fool nvidia into thinking the cards are slower, and then bam gt300 killers in desquiese. I wouldnt be surprised, these things should be performing way faster considering no crossfire overhead. Or these drivers are very badly unoptimised.

Hi Guys

I've been following this thread for some time now.
My Sapphire 5870 arrived and i did some testing.

I ran the VANTAGE on performance setting.
GPU P11900 and CPU P12600. :(

Surely i should be getting higher than this? Thats the same score i got with my 4890??? Any ideas?

PC specs:
ASUS M3A78-T
PhenonII 940BE @ 3.6ghz
8gb DDR2 800mhz
850w Corsair PSU

I've made sure i don't have AA on...so i'm pretty stumped here with this low score. :shrug:

BTW I've ran a quick OC (GPU 900 and MEM 1250 def volts) with MSI afterburner and score stays relatively the same.

Oh boy, I finally managed to finish the article about HD 5850. Now I need to go and relax a while untill I touch these cards again for some serious OC! :D

nice review LAB 501 . seems like from that review the gtx 295 is still leading apart from hawx bench. :)....http://lab501.ro/placi-video/ati-rad...micul-gigant/6

Here is a question:In the msi afterburner i didnt see any vMEM increase option.
So i am guessing the vMEM will increase only by soldering???

Run it at 1680x1050 at stock clocks at the Extreme preset ( or better yet run it on the default Extreme preset if you have the display for it ) I am curious as well as you are not the first person to get around 12000gpu on the P setting with a Phenom II. This should at least tell us if its being bottlenecked ( as 1280x1024 is still very cpu dependent and P mode doesn't use anti aliasing )

Yes, does extreme setting eliminate CPU bottle neck? I can't see the guys system specs for an apples to apples comparison.

test if u are using pciw 2.0 16x

besides that, i experienced serious slower figures with pcie link aspm (some power saving) enabled in bios. and you should enable catalyst AI..

I've checked PCI-E speed using GPUZ and it is running x16.

I will have a look at bios setting when i get home from work.

Thank you Dan. Yes, in terms of absolute performance for one card, the GTX295 still has the edge. The HD 5870 offers a ton of advantages though (single GPU, low power consumption, lower noise level, lower temps, lower price, etc), beeing a very elegant high-end solution. And HD 5850...I don't even have to say it. I think it's more bang for the buck as the HD 4850 was at it's time :)

Did anyone bother changing TIM on their 5870? Is there any point?

I don't think you will gain much from that, gone are the times when videocards would come with white goo betwen the GPU and the heatsink.

I took my 5850 apart last night to check the memory modules. I also changed the standard thermalgrease for Arctic Silver 5. It lowered my temps after 5 minutes of Furmark from 73 degrees Celcius to 71 on stock clocks.

I guess it's up to you if you think it's worth the trouble.

Looks it then! :shocked:
MX2 or MX3 could probably gain 1C more.

That would be nice.... But it also shows the stock paste is not bad at all.

I recently switched to MX-3. Its the best i found so far. MX-2 is also good. After that i would use AS5.

I know i'm not in the best place for asking this but LIGHTMAN could you do me the favor and tell me what's your GPU Score in 3DMark Vantage performance with the 5870 stock clocks?

I would truly appreciate it.

Got the XFX 5870 past 1Ghz.

Stock cooling. Just changed the thermal paste by MX2 (didnt really do anything for me, no change in temps ).
