Now that's what I'm talking about! Very nice!

Can you increase the RAM speed a little without losing stability? If so you might score another MH/s. I'm thinking around 350-360 MHz.

With lots of tweaking and testing the best I've gotten from a 1000MHz Sapphire 5850 Xtreme @ stock voltage is 413.3 MH/s (fluctuating between 413.1 and 413.5). If you can beat that then please let me know for some BTC.

Can you push the core clock any higher than 1000 MHz? Are you bound by Trixx or by stability?

can you told me how do you reach 413MH/s?

I will but I'll give whopper a day or two to try and beat me and claim some BTC. It's not the same challenge if I give him all of the information I have.

I will say that I am using Linux headless and driving everything with ssh so whopper and I are on a level playing field. I don't know about adjusting base-clocks at bios level so I hope to learn some more myself with this little challenge.

I'm running linux headless, so I use aticonfig and adjust my base-clocks at bios level.

I will try to do some optimizations, I will let you know Wink

-w 128 gives me better results with my 5850.

Interesting. When I change to 128 my rate drops by a full 10 MH/s per 5850. Perhaps there are other settings which need to be changed in tandem to yield an improved rate.

Could you let me know your other settings? RAM speed, SDK version, Catalyst version, kernel type/version/patches, kernel parameters.

If your comments can improve my rate I'll tip in BTC.

if have better result with -w 256 ^^

If I use SDK 2.1 I have to use to an other version of AMD Catalyst isn't it?

ok with my actual HD 5850 I reah 395MH/s with 1000/300 at 1200mV (80°C)

I wanted to push a little and reach 400MH/s

You can probably reach 400MH/s by playing with the software rather than pushing the card further. I've found setting which will give me 413 MH/s for a 1000MHz 5850 but you might have to pull that back a bit if your rig is not a dedicated miner. Let me know if you want details.

Do you have the latest miner kernel code? There have been some improvements in the last few weeks.

I use GUIMiner (last version) with those option :
-v -w 256 VECTORS BFI_INT AGGRESSION=13 FASTLOOP=false

Is there something to change?

The settings you are using are very good for these cards using phatk (I can only assume GUIMiner uses phatk). Now that I see that these settings are good I ask whether or not you are using SDK 2.1. For me SDK 2.1 is a fair bit faster than SDK 2.4 (with either Catalyst 11.5 or Catalyst 11.6). If you are currently using SDK 2.4 then I suggest you give 2.1 a go.

Another thing to consider is whether or not the read-out from GUIMiner is taking a moving average before displaying the hashing speed. I know phoenix does this by default and I have to pass it '-a 1' to make it stop. If you manage to remove the moving average filter from the readout then you may see your hash rate jumping up and down, perhaps by a few MH/s. Try to reduce this jitter as much as possible by closing other running programs and/or reducing desktop effects/resolution if your card is driving the GUI.

Finally, because your clock is as high as 1000MHz you may find you gain another megahash by increasing the RAM frequency to 350 or so.

It may behoove you to read this thread: http://forum.bitcoin.org/index.php?topic=25860.0
You can use Phoenix with GUIMiner now, I believe, and this modified phatk kernel really does make a difference on my cards, YMMV of course.

hi

i can not reach over 1000 MHz on Trixx how do you do to have more?

I used AMDOverdriveCtrl and Catalyst 11.6 (I'm on Linux).

Edit: You can also use aticonfig directly, all that's needed is Catalyst 11.6. To set the clock rate to 1020 say on your first card use:
aticonfig --adapter=0 --odsc=1020,0

hi

It's GPU specific. Some can be pushed as high as 1075mhz, and others will start freezing even at 910.

If it's a 'sour GPU' so to speak, then it simply can't go past a certain point no matter how much voltage is applied.
Though usually the premium ones are binned for the top of the food chain (best 5870 cores to the 5970, best 6970 cores to the 6990)

What's that utility you have there that lets you adjust clock speeds and mem speeds? (program that says sapphire in the screengrab) As I could really use the help for my HD 6950 card

If I can't unlock shaders,what would the optimal settings be for my card for mining?

Thank you

Thats Sapphire Trixx (not limited to sapphire cards only) , it allows for overvolting on some odd out cards. The interface isn't as good as afterburner however.

Hey guys, I've had a few people say that my 400 MH/s hash rate must be a fairy tale, I wanted to post a pic eventually, but now seemed like a good time to post a pic of 1000 MHz core with a private beta phatk kernel , my highest hashrate yet!

I'm too scared to go over this voltage, I don't want to push it too far

What is the current record for a 5850? (or at least, one on air/reference cooler)

Also, you can't RMA oc'ed cards. Or you can, but you'll just end up paying shipping and not getting a new GPU in return because they test cards.
Overclocking and running non-stock voltages voids the warranty.

Please explain the testing manufacture's use to determine whether overclocking has occurred or not.

Saphhire just RMA'd my 5870 that I toasted. I didn't touch voltages but I certainly OC'd(980) the hell out of it. Best part is that it was only at 70c with .5amp fans blowin on the backs and front of the cards.

These "you can't rma an OC'd xxxx" is just a myth the manufacturers keep putting out because I doubt they CAN test the card. I'm sure it's some chinese guy who throws the pc part into a machine, the machine goes "it's busteded" and he go's ok! And sends a new one back.

This is what I don't understand. If you overclock your card but you don't touch the voltage and you keep the card cool (say 50*C), what causes it to "toast"?

I know that one of my 5850's goes over 1000MHz on stock voltage (1.0875V) and is able to sustain it for hours (I haven't done a 24 hour test yet). Everyone else on the forum likes to raise the voltage before bringing the clocks that high and I wonder what I'm missing.

I don't want to kill my card, indeed I'd like it to last a long time, but I feel like it would be wasteful to keep the card at stock clock (725MHz) or even just at 850MHz or so.
