The idea for this thread; post the model of your 270, the part number, OS and version number if applicable, and notable bios changes (clock speed, volts, custom jobs like stilt bios), your complete conf file or batch file settings (minus user/pass of course), and a screen shot of your cgminer/sgminer after approx 12-24 hours of running. Might also be worth noting what pool or type of pool you are mining at so judging rejects is a better gauge.


XFX 270 2GB
R9-270A-CDFC
BAMT 1.5
Bios volts edited to 1.1 otherwise stock

I'm mining for scryptguild, profit switching type pool.

You guys have some amazing cards. None of my cards will run at 1.0v at 1000/1250, insta-crash. Likewise at 1.1v at 1120/1250.

2x MSI 270 Gaming
3x Sapphire 270 Dual-X

Windows 8.1 Pro 64-bit, Cat 13.12
cgminer Kalroth

My brother is using 12 of the Sapphire 270 Dual-X, 100365BF4L to be exact. He's using my setup exactly, and geting 475-485. What model of the Dual-x do you have?

Edit: Now he is using stock volts fyi.
 
My Sapphire's are the same, 100365L and the BF4 edition. Of those 3, one has Hynix RAM and is the weakest card. Won't budge 10mhz over 1000 or I get driver crashes at 1.1v. It does about 445 hash, didn't make a distinction above. To get 485 hash out of 1.1v is like a new record. I'm pretty sure that's better than the 750 Ti right now.

Edit - I switched over to sgminer using r2h's exact settings apart from clocks. Wondering if it will make a difference. I'm doubting so but worth a try. One thing I've noticed on these cards is a 10mhz bump is the difference between completely stable and blue-screen. Passes the driver crash step or even a hard-lock and goes directly to BSOD. I'm still eeking out some performance on 3 of the cards but they will all be within 20-40 mhz of each other on the core.

I can hit 480-490 hash on all but 1 card but they need to be at 1.188v or more, not worth the extra wattage (around 900W) when they run 460 at 1.1v (around 720W).

Although they are not 270's they are 7870's. I am using the latest Kalroth version of Cgminer

all my 270's seem to never go above 430khash

1000 core -- 1475 mem (any higher and I'll get sick or dead GPUs)

Most are HIS or MSI 270 cards.

Cut your mem down to 1250. The 1280 shaders on the 270 can't saturate the bandwidth that is there at 1250. The only memory frequencies that are of any use to R9 are 1250, 1375, 1500 (and 1625 1750 but cards can't usually hit those). That's the highest frequency in each memory strap. The Stilt found that most bios he looked at had borked memory strapping anyway, and you actually have higher total bandwidth at lower memclocks because of tighter memory timings. That was the basis of his bios he released.

Edit: One of The Stilt's last posts on the topic before he got butt hurt. https://litecointalk.org/index.php?topic=15902.0
 
Yup, drop memory down to 1250 and see if you can get that core higher. Unless you're running at like 1.0V or less, I can't believe 1000 is the limit of your core clocks.

This is true. Most 270's are able to run dang close to 1100 on 1.1v. I have 10 that will run 1120 at 1.1v and 4 that will do ~1085.

does u guys think this config setting for first gpu (290) and 2nd gpu (270x) is okay or not?

on gpu 1 (270x) I have 1 HW error. is that okay?
