Thanks :)
Yeah, since I raised VTT a little, it works. Not sure whether 1380 or 1360 ram is faster, kinda depends on the App I'm benching too.
Hey sorry if this is a dumb question going to make the switch over from my dual gtx295's to dual 5870's. Is there only specific brands of card that supports voltage adjustments through afterburner?
Nope.. works on all of them ;)
As long as they are reference design of course.
I just saw this non-reference XFX cooler on a 5870 at my local retailer. I've never seen this one before, is it exclusive to XFX or is it a new variant of the reference design?
Looks like the Vapor-X cooler - same PCB layout, different cooler.
reference design or MSI :DQuote:

Hope so. If you look at the rear of the card it has the same shroud design as the original. It's almost identical, like they have simply moved the fan. Let's hope it's a new reference design, I love it! Much prefer this one to the original, and it should be quieter to boot. :yepp:Quote:

I have a Sapphire HD5850 BBA. The idle temperature of VDDC is 34C.
Can play any games @1030Gpu/1250 with no problem, just in Furmark VDDC gose to 120C and freeze.I keep fan at 100%.What should I do?
Don't use Furmark?Quote:

Hope what I'm doing will worth the spendings.
Just got Sapphire 5850 and flashed to MSI BIOS,
after installing MSI Afterburner 1.5.1 I can't access Core Voltage slider, it is all greyed out. I've tried setting Core control in settings and even using that MSIAfterburner.cfg file to enable overclocking but no go...
Latest drivers 10.3, Windows 7 64-bit.
Any ideas folks?

Why not you change with RBE in BIOS the slider's maximum value for the GPU and memory and after that use the MSI Afterburn to change voltage.Quote:

Right now I have set up overclocked profile with Afterburner but it changes to it only when Afterburner is running, if I turn it off than card enters default 3d clocks when I play a game (checking with gpu-z). How do you guys make overclocked 3d profiles?
I think Afterburner has to be running for it to work properly, but I'm not so sure as I can't get it to really switch profiles automatically like I want it to, it pretty much stays overclocked until I change it myself.
Is it still possible to increase voltage using RBE? even on non reference cards?
Is there a convinient way of having 2d and overclocked 3d profiles switching as needed and such.
I'm sure someone has mentioned this and I will again for new people. If you're running Crossfire and getting locks/freezes with MSI's Afterburner it could be because of ULPS. I have to disable that to OC my cards with Afterburner otherwise I'm stuck with the CCC's OD. Also Crysis will lock at the menu with ULPS on using Crossfire for me. Seem like it switches cards 2/3 off then.
http://www.xtremesystems.org/forums/...&postcount=100
Switching it off and on is easy, just change the value and restart.
Yes, you can use RBE for this, to do this you need to go to the Clock Setting tab of RBE and click the "GPU registers" button under Voltage Registers.Quote:

Flash your card, and your card should clock to 157/300 unless you're running 3d, when it will run your overclock.
If you want to be a little safe about this process, you can first flash just the voltage register and leave the stock clocks, and you can test to make sure your card is properly setting the voltage under stress.
been looking over this thread. bout to squeez trigger on this sapphire vapor x 5850. I read some comments on egg and another site, that recently the pcb was switched over to one with weaker vrms or something i forget. Im looking to do at least 950 on the core with stock voltage, not interested in flashing a MSI or other bios onto the card.
anyone know if this revision is decent

Can you raise the voltage of XFX HD5870 XXX, model with fan in the middle?
Why don't you download afterburner and see? :DQuote:

Others who have lightning card, can you show me your clocking.

Yeah, when I downloaded MSI Afterburner it came with Kombustor, a Furmark made tool.
I think people say "don't use Furmark" to mean that you can't use Furmark as a sole basis for stability. I have been Furmark stable for 30 minutes, but have found that during games I might get lockups or crashes I wouldn't normally get, and it has to be attributed to an overclock that isn't truly stable. Sure the games run at a lower temp and don't seem quite as demanding, and they run fine 95% of the time, but every so often they'll have a short hiccup or something I wouldn't get if I turned down the overclock.
I haven't used GPU Tool's artifact scanner, I will have to give it a try. OCCT's GPU stress test has an error check, but it notes that the error check reduces GPU heat because of large data transfers required for the error check comparisons.
So what program would be the best, or one of the best to use for stability?
They do, yes.Quote:

IDK in other countries but in myne, reference HD5870 is facing out very fast. Now the only reference card left is sapphire and I don't see anybody here using it, maybe there's a reason for it, again IDK
But, I'm hesitating about my interest towards the Lightning since I read at some threads, users were reporting that they don't respond to AB voltage setting and MSI says its a known problem. Sissh!~
Finally broke Vantage P 32K for two HD5850 cards in CrossFireX :up: :D I think 33K is out of reach as the overall score, but I do already have 33.35K for GPU only :p:

Yesterday got Sapphier 5850 reference card and today i flashed a modified asus 5850 bios (with up voltage and Mhz).
The problem is that I see 400Mhz on core and 900Mhz on Mem always, when I put in bios to 950Mhz and 1200Mhz.
What is the problem ?

Hey guys, I just bought a powercolor 5850 pcs+ on sale at zipzoomfly for $270.
It has a non-reference board and I was wondering what's the best way to overclock it? Can the non-reference boards be overclocked through a bios mod or am I limited to just a hardware mod.
Also, if I perform a hardware over-volt, does that voltage then get applied to both 2D and 3D clocks? I would like to keep the low power consumption in 2D but up the volts for 3D.
So is there any way to increase just the 3D voltage on a non reference 5850?
Thanks
Your PCI-E is running @ 8xQuote:

Some online reviews of this card have shown overclocks up to 950 core. You wouldn't be able to change voltage through the bios either.
There are a few threads on XS about doing hard-mod's, I wouldn't know too much about it as I haven't done it. I would expect that all voltages would increase.
someone has a pcb shots of his 5850 icooler version? it could help me with oc.
im just wondering if many people have had 5850s die after using vGPU of around 1.2v and higher. sorry if its been discussed (too many pages)
Hye guys, need to ask to those who achieved clocking HD5870 to 1000/1300 in stock HSF, didn't your VRM temp shoots very high? I'm trying to find solutions for that but my country is not selling the VRM-R4 and VRM-R5 heat sink for time being, so anybody found any other method should I just leave it like that and worry less about it?
Thanks~
Have a question to ask regarding the clocks I am getting on my 5870. Trying to figure out what the official stock voltages are.. Keep reading it is 1.125 and other places say it is 1.162. Using Afterburner it shows 1.162. But just to test I ran it at 1.125 to see how far it would go with just that voltage. Hit 990 easy on stock. This is what I got below... (Ran the kombustor multiple times)
http://img132.imageshack.us/img132/1...ageoverclo.png
My question is if 1.162 is stock what is safe to push the voltage on a 5870? Because it looks like I have some headroom.
My 5970 running @ 1100/1300 @ 1,412V

Quick question.
What is a sensible voltage to run a 5870 at, with water. Low temps, 50's at load for V reg and cores.
Usually I'm happy with 0.1v over stock. What are the expereinces at 1.35 with these cards.
What is the highest factory set voltage on the premium range of cards?
here is mine at 1.35V on GPU's it will run Vantage at 1090, dX11 games and Dx11 benches at 1070. at 1062Mhz I have played most of my games, Crysis, Crysis warhead, mass effect and 2, COD 4 and 5 BF2, and Dragons age for hours on end an no issues. makes me wonder why the hell I waited 6 months to get the 5870...

Guys, I have seen a few hwbot scores using 1100+ on WC 5870 core clock, do many clock this high? Do they need higher than 24/7 voltages to get over 1000? I have been offered one locally but it can only do 1050 at 1.3v, is this typical? I will be water cooling if this influences the clocks much.
Some may get that high, but I'm sure he was using some extreme cooling methods. YES. YES.Quote:

NO it does not. This is the absolute worst 5870 GPU that you can get. There is NO difference in benchmarks even after overclocked. It has no adjustable voltage regulators. I have this one, and I'm going to RMA this piece of :banana::banana::banana::banana: soon. :down::down::down::down::down:Quote:

I've had three HD5870's now, two reference, all of them need 1.35V to bench at 1000 core and are unstable.
I don't think your 1027@1.27V for HD5870 represents average overclocks at all.

If I up the voltage above that my screen starts to flicker no matter what clocks I set. Temps on core never pass 59c, highest VRM temp I have seen in GPU-Z is 66c. This card is annoying me :mad:
do i need to do anything different when running in crossfire? i have the msi afterburner utility but im not sure how i adjust both cards? same with CCC how do i adjust both cards?

anyone try sapphire 5870 vapor X ? can do overvolt with after burner ?
anytime i use afterburner to apply even a 5 mhz overclock i get a BSOD. Overclocking in CCC works fine though.
Great thread fellas. :up:
Not sure how to take pics of my desktop and convert to .jpg but here is a pic of my card -- reference HIS 5870 with EK FC5870 Waterblock. Conservative overclock -- running 1.25v - 1000MHz/1250MHz -- I haven't tried pushing beyond either of those clocks to see if it would go higher. I have been told that the memory is tough to know when it's beyond its spec because it doesn't show artifacts? I wonder how much voltage I would need to hit 1050MHz core stable.

The only other time i have seen this BSOD is when using the 10.5 drivers, anytime id do something 3d I would get the same BSOD. Is one of my card defective?
If i use CCC i can overclock no problems.
Could the BSOD be due to my dirty windows install? Or would you think defective hardware?
Look back in this thread a bit and you'll find the fix. Gotta change something in the registry to stop the crossfired cards from switching from 2D and 3D mode I think. Afterburner changes 3D clocks and it messes it up when overclocked. Pretty easy fix and worked for me. :up:Quote:

Makes me want to scream seeing all the 950 -1000 clocks all of you have been reaching. I'm sure this one would hit those clocks if i could just push the voltage to it. Apparently i'm not the only one with this problem so i would strongly advise everyone to steer clear of this card until it's fixed. If it's even fixable.
Anyone else having problems around ~1.150? I'm curious if i've just got a bum chip or if it's this card in particular. Pretty sure it's the card though.
No point in posting any scores as 865 isn't that impressive.
Hi guys!
I have a first expressions with 2x5870 and i have a problem with oc. Whatever i will set in afterburner or ati overdrive (core 950 mems 1300) score in 3dmark 2006 is always the same- 20 to 30 marks more or less. Im benching on 4,2 ghz so i think that its not to low. Any idea why i cant gain any FPS boost?
My max stable speeds are 939/1250 on stock, using XFX 4890 non-reference edition... (fan in the middle) pity the gpu voltage can't be increased for more stable overclock. the memory is touchy and does'nt overclock well, however there is little performance increase with overclocking memory as well. strange is that when overclocking there are no visual artifacts what happens is just the game will crash and then driver is re-set. must be the 5800 series gpus that started doing this, as i'm not used to how they behave now.
These Zalman VF3000A's are working pretty good, here quick Vantage run with my 24/7 os, score is poor but i was just testing..
