I'll go take a screeny in the other room on the mininer istelf, I assume that it's actually dropping the mem clock because when i drop it i loose 12°
I have an MSI 6990

http://imageshack.us/f/12/unlednfw.png/
As you can see here, i can put the mem clock Much lower, Or the core Much higher

Maybe MSI doesn't have this restriction.... I'll have to hunt one down. Too bad I've sold 5 of them already without trying them... (to pay for 2 sapphire 6990s I kept for myself LOL)

Appreciate you posting this!

I am more than certain that it's not my specific cards, Have you gone into MSIa and under the EULA and typed:
[ATIADLHAL]
EnableUnofficialOverclocking = 1
UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 2
AccessibilityCheckingPeriod = 0

Once you do this you can set whatever clocks you want on whatever card you want, NOTE: MISa becomes very "tweaky" after you've done this, (EG: drag mem to lowest, Hit apply, Close misa, Reopen it, And it can go lower)

Yes, I surely do know how to use and setup/configure MSI AB for OC'ing. was one of the first things I learned when I started with bitcoins...

still, if you look through forums regarding 6990s you will see that people are unable to underclock memmory outside the parameters I mentioned.

I will hunt down an MSI board and see if it behaves differently. Will post back here, but it may really take a while...

Huh., Funny.

how did you set the 6990 to 600 memory?

MISafter burner.... make sure you've "enabled unofficial overclocking"
Hell i could drop it to 300 right now if i wanted, but it crashes when mining

Hmmm... I'm very puzzled... there have been posts after posts about the limitation of underclocking 6990s
i don't know how you're able to do this. Which 6990s do you have? maybe yours are some particular brand that allows this...
basically i can set the values using MSI AB or whatever other program, but if you actually lookup the memory speed with say GPU-Z it won't run at the specified memory setting. On 6990s, for pretty much most people here, you can only set the memory clock by 125 less than the core clock. ex: 930/805, 940/815 etc... etc...

If I try something like 930/600 with MSI, the core speed will be set at 930 but the memory clock will be at the default setting(1250 i think?) according to GPU-Z...

So, i'm very curious whether you could verify what the actual memory speed is reported at when you down-clock it.

Radeon gpus in general run hot..
You should worry if you break the 85~90C barrier.

I feel safe below 80. But some ppl do run their cards hotter.

yeah, i am part of that "some ppl".
Used to run my nVidia's at 100C+

cards will run just fine as long as it is under 105C.
Know that all modern cards have auto throttle when it gets to danger zone, which is about close to 100C

are you all reading just the core temp? if you use something like everest/aida64 you can monitor the core temp, memory temp and shader temp. most of my cards are within 5C for the 3 temps but one of my 5850s is reading 75C core 72C mem and 95C shader, it seems fine and stable but i am a little concerned so im watching it closley

dunno in their cases, but you can use GPU-Z, it's one of the favorites out there...

FYI running fans at 100% 24/7 will exponentially decrease the lifespan of the fan

Without a doubt. And they spin slower too, So your 100% will eventually be like a 60%

.... Then how exactly am i mining at 1ghz with 650mem

Swapping to 982core and 1000mem and going to run CS:S video stress test at -f250
To test the theroy of 100+/-= no bugs

Too much heat. im expecting to crash and i dont want to deal with that crap. Flipping back to 962core 1150mem

it seems that dual-GPU cards have these limitations. 6990s have them, now this dual 6870 has it too. seems like any dual-gpu 6xxx series is limited to how low memory can be set to in comparison to the core clock speed.

i thought you meant you had a dual-gpu 6870, but i see now that you have 2 cards actually.

Uhhh buddy? I have a 6990 running at 930core 600mem, Your still wrong

982core and 1000mem showed no glitches and everything went OK, aside from Notably slower memclock loads, But the 5° drop is seemingly worth it in the mining senario

how did you set the 6990 to 600 memory?

Dual6870BE's(gaming rig) Very clusterfucked tight packed Both cards run @ 85° for the past three weeks mining, WHILE gaming, No issues
6990 Open case/20inch box fan= 87° running 1month no issues
5830 same case 78° 5months no issues

Dual 6870's overheat at 90° and auto shutdown, I wanna run them at dual 1ghz but i can only run them at dual 981mhz due to heat

Which 6870 are you running? are you able to underclock the memory to low setting?

http://www.newegg.ca/Product/Product.aspx?Item=N82E16814150520&Tpk=zdbc
I have not attempted to drop the memory clock on these cards since i use the Often for gaming. I will go try to drop the mem and start mining

Dropping the memory clock to 575 cause graphical errors, But no crash, Nor any Sign of crashing, just Blatent Card Display failure due to too slow of a mem clock im assuming
Both cards are running and linked crossfired

I am going to raise the memory clock to see if i can remove the "damages" since i feel that these "skews" are actaully Hurting my cards

I've been experimenting with this:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814131446

and so far the memory clock speed can only be lowered by 100 less than clock speed. ex: 900/800, 930/830 ect...
can't go less than by 100.

tried flashing bios. seems some restriction is on the card and/or windows catalyst driver. damn thing detects that bios was flashed and keeps rebooting computer.
have not tried under linux. read some posts that implied that under linux flashed bios are working... if so, it's probably windows driver limitation then.

As of right now, both 6870BE's are running at 1020mhz core and 700mhz mem, The temperature on both cards appears to be a stable 78°

Holy fucking failure, Cards crashed and reset, and one card is running at 1020 the other at 300, And i cant change the clocks, Uh oh

Clocks are responding again, I am going to attempt to run at 982core and 1000mem for a temp drop, Then try to mine while gaming.

On another note, My cards have gathered some dust and the overheat while gaming+mining @982core and i had to drop it to 962core
