<GrammarNazi> "Radeon 7750 and 7770" is a plural subject; you need say, not says. </GrammarNazi> Hey dude! I'm French! Give me a chance But there's no plural for "say"? I know "Radeon 7750 and 7770" are plural, and that's why I put an "s" to say. The plural form of "say" is "say"?

English isn't a language that makes any sense; don't expect it to.

Correct. "A and B say hi" is the plural form, and "A says hi" is the singular form. Additionally, "I say hi" is the correct singular form when using "I", and "We say hi" is the plural form when using "we". It gets a bit confusing sometimes.

It's probably the first time in my life I hear "if it's plural you REMOVE the s"... English isn't a language that makes any sense; don't expect it to. I agree. I never understood the "Oh, you know, English is easy to learn!". Yeah sure, if don't mind that like 85% of your verbs are "irregular" and that words are chopped in half everywhere. "The 've? Oh, that is the word "have", you don't recognize it? I know, it's missing 50% of the letters, but it's the SAME thing!" Took me decades to master this art...

I get 224 mh/s on my 7770 @ 15% oc. Yeah, I noticed that your rates were higher... you should definitely add your cards and settings to the bitcoin mining hardware wiki. At the time of posting, this was the highest reported rate I could find on the boards.

At the time of posting, this was the highest reported rate I could find on the boards. That wiki is a good starting point, but it's not at all complete (or accurate) half the time. Maybe I've been lucky, but I've always gotten 10-20% higher than what that list says I should be getting on my hardware.

The wiki is wrong beyond repair. There needs to be a cleaner peer-reviewed complete list... Yeah, I noticed that your rates were higher... you should definitely add your cards and settings to the bitcoin mining hardware wiki. At the time of posting, this was the highest reported rate I could find on the boards.
It's just a regular 7770 at 15% OC... no voltage changes... default cgminer settings..

That performance is to be expected, it shows how gpu architecture as bottomed out since it is the same performance as 5770/6770.

Eh, I'm only pulling 60w at 200MH/s, I'm happy enough with 3MH/s/watt.

That's correct. It has a six-pin connector because it occasionally draws >80w when overvolted or in things like Furmark. The rated TDP is 80w. I'm running 1100MHz core and 651MHz RAM with my power control (limiter) setting at -9%. The power control setting is kind of neat, the card throttles if it gets above a certain power usage in watts. Using diablominer with -v 1 -w 256 -f 10 It's actually a great card for $100, essentially it's 1/3 of a 7970.

Picked up one of these about a month ago: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125417It's a 7750, factory-overclocked to 880 MHz. At stock settings, it'll do about 133 MH/s. Temperature is usually in the low 60s; fan speed stays at 39%. I just started playing with the settings in bfgminer a bit ago. Turned on fan and GPU-engine autotune...fan stopped until the temperature hit 75°C. I can slow the memory down from 1125 MHz to as low as 750 MHz; it got set back to default if I tried 600, 700, or 725. Kicked GPU speed up to 950 MHz...144 MH/s, 70°C, 33%. Kicked it to 975 MHz...something got wedged and I had to look up how to force a reboot: echo 1 >/proc/sys/kernel/sysrq echo b >/proc/sysrq-trigger
Looks like fsck completed OK and bfgminer restarted at stock settings. I think I'll keep it there for a little while.

I'm running the ASUS HD 7750 factory overclocked to 900, using MSI AB to get 1000/850 for core/mem. Running GUIminer I get stead 148.5 MH/s using -v -w 128, slightly higher with -f 10 but then I can't stream videos... Its been stable for at least 4 days with temp under 70 and fan under 50%. If the card is pulling the 55W it claims then I'm getting nearly 3 MH/W or about $20/BTC. I'm going to start playing with the power and voltage but I'm a little scared since I'm new to this. Tacotime- what card are you getting 200MH/s with?
