My video driver always stops working when I try to raise the core 865+, with 320mhz memory (fan manual 60%), with stock voltage, on 5850 shappire extreme and xfx.
Anyone have the same problem?

Do you use stock coolers? In auto mode or on 100% rpm?I can't get, how do you keep temp at 68C.
My cards are separated with pci-e risers and heat up to 75-80C.
What software do you use for OC, MSI AfteBurner?
My 5850s are the sapphire xtreme ones, stock coolers running at 65-70% fan depending on the days temp, running at 100% will kill its life time
I'm using sapphire trixx for the OC, not sure why you are getting such high temps, maybe your OC software is automatically bumping the voltage.
I found that my 5850 Xtremes with stock coolers and stock voltage would run at around 72*C and 78*C even with the fans at 100% (not recommended). At the time the ambient temperature was about 20*C. Ventilation wasn't the best but it was ok. I'd imagine a single card would be at around 70*C but haven't verified this.
Perhaps noogai93 has good ventilation, low ambient temperatures, or is using case fans or something to blow cool air between the cards. If you're struggling to obtain low enough temperatures then I'd consider undervolting the cards.

I got mine up to 411Mh at 1000/333 but it wasn't stable and I didn't feel like bumping the voltage.
Right now I'm happy with the 402-3 Mh I'm getting with 975/325.
Your doing something wrong if you need 975/325 to get to 400 megahash. I only need 950/325 to get 400. Are you using the sapphire card? Right now I'm happy with the 402-3 Mh I'm getting with 975/325.

I have a HIS Radeon HD 5850 that I cannot OC past 775Mhz, 600 Mem . If I raise it just by 1 to 776 the card crashes and the rig needs a cold reboot. I have a 2 card rig (6950 ref and the HIS 5850). The 6950 pushes 430 Mh/s but I cannot get the 5850 to break 303 M/hs. I clearly must be doing something wrong.

mixing is not an issue on win7 64bit proffessional. two ref 6950s with a non-ref 5850. 6950s at 430mh/s with the 5850 at 390 mh/s.
but perhaps linux is different? just throwing my windows exp out there.

The problem is that I can't lower Memory Clock too much cause I use my comp for other stuff other than mining too. So I try to leave it at 900 mem clock togheter with 900 gpu clock @ 1.125 voltage, but that ocasionally crashes my gpu.
Have you tried using phatk 2.1 or phatk 2.2? It has an option "VECTORS4" which you could give instead of "VECTORS" which might improve your hash-rate. "VECTORS4" is basically for people with high RAM clocks. Don't forget to lower your WORKSIZE too. Here's the main thread.
I see, thanks for letting me know, but sadly I'm using poclbm.

I found my old post about my personal best MH/s for a 5850. 461.1 MH/s at 1110 MHz core clock, 3 hours continuous with very few stales.
Higher clocks such as 1140 MHz were fine for a short time but after 30 seconds or so the cards cut out due to high temperatures. I couldn't find a way to circumvent this so I guess (I have no water-cooling).
As I said before, I don't run at these speeds normally - this is just a bit of fun. The same card is now running at 377.5 MH/s (899MHz/[email protected]) and I'm trying to get my miner up to 2.5 MH/J.

whoa.
that's quite an undervoltage. what's the temperature?
Right now my temps are 57*C and 43*C respectively (one card is sucking in air being heated by the back of the other). The miner is in a pretty small room and if I cut off all ventilation for 12 hours or so the temperatures can reach as high as 62*C and 48*C (peak from the last two weeks). This is with all fans turned down to minimum to reduce noise as much as possible. If I turn up all the fans and keep the room reasonably well ventilated the temps sit at about 44*C and 36*C.
I've been through a phase of maintaining high clock rates but I much prefer having a cooler and very quiet miner achieving more than 2.4 Mh/J and I certainly don't mind sacrificing around 100 Mh/s (from 828 Mh/s to 733 Mh/s) for this.
I wonder if the cards were cutting out due to GPU temps or VRM temps?
If it's not a reference cooler (in which the heatsink contacts the VRM's via thermal pads), maybe try using arctic cermique (sp?) to glue on some small heatsinks to the VRM's

Good question, I've wondered this myself. I'm guessing it was the GPU rather than the VRM that was suffering simply because everything was fine for 3 hours at 1110 MHz and consistently died in seconds at 1140 MHz (same voltage). When I replaced the stock cooling I was not able to improve the VRM cooling and the sticky pads and stock heatsink remain in place. For the testing I had a fan-heater turned to cold and focusing a blast of cool air on the VRMs. I have no way of measuring the temperature of the VRMs and can only assume they were roasting.
Thanks for the tip but I'd rather take good care of my cards by running at lower settings.

Right now OC'd at 900/600/1.125 with TRIX. My 5850 is a XFX. I was trying out this new OC setup and my card crashed while I was typing this. Idk what's wrong with my card but it seems that it just can't stand having a 900mhz clock at 1.125 voltage, I need to pump it up to 1.150 so my card won't crash. Also, it hashes around 350mh/s @ 900. Yeah, I think I just got a god damn crappy batch.
Lowering the mem clock to around 300 should help. If it becomes unstable below 600 try a different version of its drivers. I switch from 11.6 to 11.7 and from afterburner to trixx and that fixed all my problems.

I have my 3x5880 at 950/300/1088 giving 389 Mhash/s with Linux (using atitweak) and perfectly stable.
I have the feeling that I can go more far away with them, they are only at 69ºC with the fan at 70% but I care for the PS. It is a Corsair GS 800. Do you think I can go higher with it ?

The only thing I don't like about Trixx is the fact that it keeps setting the fan speed back to default every time I restart my computer instead of using the custom fan profile I setup.
It saves my fan profile, but I have to manually click the custom fan profile setting because otherwise my card overheats on the stock fan profile. That's the only reason why I don't use Trixx.

^me too, but I never have much success with Afterburner, at least not for multiple GPU systems. Trixx on the other hand seems to work well for me, it's cleaner and simpler too, which I like....
I'm curious what would cause afterburner to not work but trixx to work perfectly fine?
Usually for me, if Afterburner won't work, TriXX will. The combination of both usually will let me tackle any problem (except my third dedicated rig, which has crossfired 5770's... for that I'm experimenting with BarelyClocked, and it seems to be a VERY powerful commandline tool, possibly written by a bitcoin forum member)
I tried trixx again since I changed to 11.7 yesterday and haven't tried trixx since the change. That fixed everything. I still cant use afterburner though it makes the cards extremely unstable. I'm running at 940/325 and I get 390
Yea I just got the sapphire extremes from ncixus for 145. Anything below 500 tends to freeze the entire computer 
You say the new bios for the 5850 may be more restrictive? How hard would it be to flash to an older version and would I risk bricking them?

I got mine from them in that last batch as well. No problems here on 300. So far these cards let me throttle them at will long as they have ample voltage.

I'm genuinely surprised that low RAM clocks cause your computer to freeze. It doesn't seem logical to me and runs contrary to the collective experience of the forum members. Are there any other programs using your cards? Is one of your cards driving a window manager for example? Have you tried lowering the RAM clock on a card which is not being used by any programs?
I'm not the best guy to ask about flashing BIOSes and just try to do the best I can with the given BIOS. There was a time when I was limited to 900 MHz core clock which was very frustrating but flashing the BIOS was simply too much work to be worth doing.
Best of luck.
Some cards have way more safeguards than others, the XFX for instance is a pain to overclock..
Try MSI afterburner and TRIXX, if you are not able to do it, flash your BIOS, but be sure to know
what you are doing, because you are going to void the warranty of your card.

Do you guys have to change the voltage to get the memory so low? On stock voltages I have a really hard time with anything less then 500.
I ran 900/300 on stock voltage. I have the Sapphire extremes if that makes any difference. Card was stable and started to crash driver in the 900-925 range. Lowering memory on the other hand has never made it unstable for me.
My cards run fine with the RAM at just 50MHz with no change in voltage. I doubt there are stability issues with low RAM clocks.
I'm assuming you're having difficulty setting a low RAM clock speed in the first place. For this I use AMDOverdriveCtrl. I create a simple overdrive profile such as
Code:
and then apply the profile to the card with the command
Code:
AMDOverdriveCtrl -b MyProfile.ovdr -i 0
I imagine in Windows this would be even easier. I found it was necessary to give the same RAM clock speeds for all three performance levels for the setting to apply. I don't think AMDOverdriveCtrl can handle lower performance levels to have higher RAM clock speeds but I could be wrong.
My cards are also Sapphire Xtreme's but they are a few months old which might make a difference. I've heard that the latest BIOSes Sapphire have put on their cards are more restrictive.

I am running my 5850's at 950/300 1.115v and pulling 390 mh/s.
In testing I got my 5850 over 460 MH/s (can't remember the exact figure) at 1110 MHz core clock, 370 MHz RAM, 1.25V. I can't vouch for the long term stability of my settings (I managed a continuous 3 hour run and then the card crashed immediately when I started mining on an adjacent card).
These days the same card is giving me 373.1 MH/s (890 MHz core, 300 MHz RAM, 0.9875V). I haven't tried the Catalyst 11.7 or SDK 2.5 yet as I've been away for 2 weeks. I personally prefer the lower voltage and my dual 5850 rig is currently running at 300W, giving me about 2.43 MH/J.

that is exactly what I run mine at. anything more and stability suffers for the most part.
sure i can increase the clock and it will run higher for several days on end but eventually
it screwed up and would be down for several hours until i noticed/fixed it (always at night)
thus defeating the extra mh/s i was getting.

I had 434.4 with my HD 5850 ^^
http://bitcointalk.org/index.php?action=printpage;topic=24949.0
Check that thread out for some past attempts.
I hit about 432.5 (think it was at 1010 Mhz core) but I didn't run very long because I was worried about VRM temps (114c). I think teukon even went further than that but I lost track of the thread thereafter. Instead focusing on energy efficiency as being that high voltage decrease the actual amount of bitcoin worth earned.
At any rate, my old reference 5850 (the one above) seems to get more Mhash than my second non-ref 5850. Ref version is at 920/320 1.1v and gets 397MH/s while my other non-ref is at 975/320 1.088v and is getting only 404MH/s. Tried to replicate and even installed it on my system where the 5850 ref is but no go. Just a different beast.

What sort of voltage do you use?
i make
398,8 mhash
core 964/310
398,8 mhash

What is the highest hash rate that someone achieved with a 5850 without blowing up the card?
Just curious.
