That might be it then. I'm running 2.4 SDK that puts in 2.1.0 Afterburner. I'll change them out later and see what happens. I hate when updates break stuff Sad

Yeah, I found about 10% better performance with the 2.1 SDK over the 2.4, though, if you're using Phoenix with phatk, I think 2.4 is better.

my 5770 is getting 210 ish running 950core I left the memory at 1200. And the settings I used where -v -w 128 -f 15 using the new poclbm.
I Might try 970. But I like how stable the system is right now

I'm using Catalyst 11.5 drivers and the 2.1 SDK. The SDK could be the difference if you're using 2.4.

Something very odd going on. Been doing a bunch of testing for the past few hours and can't seem to break through the 196 Mhash/s rate. Core set at 950 MHZ and stepped the memory from 300 MHz up to 350 MHz in 10 MHz increments with no change at all in hashes (or temps or fan speed). Changed from -w128 to -w256 and lost a couple Mhashes. Also played with -f1 and -f10. All these in various combinations, including the exact settings from meatball that gets him 209-211, and I'm stuck at 196 Huh

When I first start up GUIMiner I can see the first 2 speeds listed as 225 Mhash/s but it immediately drops to 196. My spidey sense is tingling.

[edit]

I just made the change to poclbm that is giving everyone a ~ 3% boost... nothing here. The first few speed ticks hit 230 Mhash/s and then it's right back down to 196. There seems to be something somewhere that's acting as a speed limiter that wont let me go over 200 Mhash/sec and when I find that damn thing I'm gonna rip it out and stomp on it till it's flat and very broken Angry

i've been running my 5770 at 970 / 300 mhz and getting 215MH/s - phoenix with phatk temp is not a problem!
go for large Wink

Try bumping your Memory up a tad. Believe it or not, in some cases I've seen better performance with memory at 320-340 vs. 300 or under. I assume at some point you underclock memory too much and things get a bit unstable.

Also, monkey around with your flags/settings on your miner, you might be able to get it a bit higher. I'm using GUIMiner with Poclbm and -v -w 256 -f 1 flags to get my speed. Bumping up to 950/320 I'm able to get 209-211 MH/s, but temps start creeping up.

I've already tried with the -f10 and it bumped me up a couple Mh/s but nothing like what I got by bumping the core up 50 MHz. What I want to do next is drop the -f setting and just run core at 950 MHz while stepping the memory from 300 MHz to 350 MHz to try and zero in on the sweet spot. Probably only do it over a smaller share range rather than the 1000+ that I have been using. Just long enough to get a stable reading of Mhash/sec and see what the temps do. Ultimately I want to run at 1 GHz core with the memory set at the sweet spot if temps aren't too bad and it stays stable. Probably do a summary post in a few days or so. Lots of real life stuff to do over the next few days.

I've been running 4 HIS 5770's at 940/320 for a few weeks at stock voltage and they've been running fine at ~ 205 MH/s. Getting only about 1% stales as well.

Nice to know that what I'm seeing is about right for my card

Did run the other test, but it ended late (early?) this morning and it was all I could do to copy the numbers down without falling asleep Cheesy

Core: 950 MHz
Memory: 300 MHz
Hash Rate: 195 Mhash/sec
1090 shares were produced with 12 stale shares for a stale rate of 1.10%.

Couldn't quite break 200 Mhash/sec but it's running well with a low stale % and the temps aren't bad. Cool

Just an update.

In my OP I was actually WRONG ( yeah, I know, hard to believe right? Wink

) Both numbers actually were right because there is more than one sensor. One program was monitoring one and the second program was monitoring the other (according to GPU-Z). Now my initial burn-in stock test results:

Card: XFX 5770
Core: 850 MHz
Memory: 1200 MHz
Hash Rate: 180 Mhash/sec
1240 shares were produced with 21 stale shares for a stale rate of 1.69%.

Not too shabby for stock settings. Doing a test on core of 900 MHz and memory of 600 MHz next....

(update)

Core: 900 MHz
Memory: 600 MHz
Hash Rate: 188 Mhash/sec
1254 shares were produced with 9 stale shares for a stale rate of 0.72%.

Hash rate went up slightly, stale rate went down, temperature also went down by about 6C.

Next test is core 950 MHz and memory of 300 MHz.

The new 5770 is in now and has been running at stock settings for the last 6 hours Cheesy

New PSU too Grin

Anyway, GUIMiner is reporting that I have a 180 Mhash/s and Catalyst Control Center reports 850 MHz for GPU clock and 1200 MHz for memory clock (the stock speeds) and a temperature of 74C. All is good so far. BUT I installed MSI Afterburner and it is saying that my temperature is 91C! They can't both be right so how do I tell which is correct and which is wrong?

Download GPU-Z. It will give you data on all available sensors. My 6870s have three temp sensors, for example. I'd trust that over both CCC and Afterburner.
