Topic: Lowering mem clock to idle speeds SPEEDS UP Mh/s - page 4. (Read 39045 times)
yes, but if it was not damaged by OCing, but I did OC it, I wouldn't feel bad by committing "fraud" to get a replacement... I never had to though, all the cards I've owned are Reference design XFX cards
doesn't matter, they can't find out you were overclocking unless you do something obviously stupid to show them you were.
Of course if you try to return a card that you damaged by overclocking, and this is not covered by the warranty, you would be committing fraud.

if you're overclocking ... you're already losing your warranty
Not always. Some companies (like XFX & EVGA) will let you overclock and still honor your warranty.

Is there anyway to run MSI Afterburner to automatically Over clock of memory also?
I did my best & it loads core clk as 1038 on startup, but memory 1050 only, then i move the slider to minimum, for me 525, apply & restart MSI AF.
Restarting shows core as 900 & mem as 1050, but clicking saved profile, brings it to 1038/360.
I want MSI AF or if any other software there to automatically apply OC, so no human interaction needed to mining.
Tried with MSI AF 2.0 & 2.1

Flash the BIOS with whatever settings you wish.
I can't loose my warranty or guarantee.

EDIT: With out loosing warranty or guarantee & also no flashing & only software based.

Bump b/c it seems to work =)
Using afterburner I lowered the memclock on my 6850 to 300 and raised my core clock to 900..seems to be the sweet spot for my card.
Im up to 191-193 Mhash/s from 169-172

So essentially you were able to maintain the same thermal profile yet increase your performance
? If so then congrats!

as i said in some posts before, which i forgot, due to get mine more, 1042 crashed.
so now back to 1038 core & 360 mem, 100% fan with temp 70C
268- 273 Mhash/s , -v -w128 -f1

-v -w128 -f 120 here
i am running in windows 7 32bit aero enabled , 6870
at present 1042 core & 361 mem with 100% fan & 73C temp
getting 271-275 Mhash/s
with flags, -v -w128 -f1

Please try this & give confirmed confirmations.
The MAXIMUM STABLE CONSTANT hash/s is obtained by a formula which i tried & found out for my HD6870. Instead of varying hash/s, it gives some what constant hash/s
Memory clock = (core clock /3) + 14
Please try, test & confirm with your results & please put your data here with your Graphics card & hash/s you get (you can add OS, 32 or 64, catalyst version & stream or APP version also).
Donations & loans are always welcome.
Thanks.

thanks!!!! However my numbers are different...
OS: Windows 7 Pro 64-bit
Cat 11.4 stream 2.4
Card: 6870
Hashrate @ 300 1020 core= 263500 kh/s
310 = 264400 kh/s
320 = 265500 kh/s
330 = 266300 kh/s
340 = 266800 kh/s
350 = 266750 kh/s (varies a bit more)
354 (1020/3 +14) = 266500 kh/s
360 = 265500 kh/s
After further testing:
341 = 268100 kh/s
342 = 267100 kh/s
343 = 267350 kh/s
344 = 267150 kh/s
345 = 267000 kh/s
346-349 = gradually down until 266750 kh/s
So best mem clocks are 341... 341 = coreclock/3 + 1
Trying with 999 core now
300 = 259000 kh/s
330 = 261550 kh/s
334 (999/3 + 1) = 261500 kh/s
340 = 261600 kh/s
347 (999/3 + 14) = 260800 kh/s
at this point I can see the /3 is the wrong correlation with the core clock.
337 = 261000 kh/s
338 = 261500 kh/s
339 = 261600 kh/s
340 = 261600 kh/s
341 = 261650 kh/s
342 = 261500 kh/s
343 = 261500 kh/s
So far, it seems 341 is a very good mem clock to start at

Glad it is working for so many of you
What miners/OS/Catalyst/opencl are you guys running?
Newest poclbm / Win7 64 / 11.3 / whatever is included with 11.3
11.3 uses SDK 2.3 (ie opencl) as far as I know..
I've go the same setup btw.
