made that change, now reaper.exe closes instantly when I open it
Edit: was using reaper v12, changed to v13b4 seems to be working
Quite a bit of slowdown in windows, what is the closest setting to intensity for bitcoin?
LTC tips for the help!
Like taco said But i have run at 12 to use my comp so it may vary

Intensity/aggression 13 or 14 is best if you still want to use the computer
People who have pmed me, I'm sick w flu, will get back to you soon
thanks taco! whats your LTC address?

Like it has previously been stated in this thread, I can't get my 7970 to run in Reaper with thread concurrencies of 20992, 21712, or 24000 and lookup gap set to 2. Reaper just crashes immediately. Thoughts?

Charlie Kelly: I'm pleading the 5th. The Attorney: I would advise you do that. Charlie Kelly: I'll take that advice under cooperation, alright? Now, let's say you and I go toe-to-toe on bird law and see who comes out the victor? The Attorney: You know, I don't think I'm going to do anything close to that and I can clearly see you know nothing about the law. 19GpqFsNGP8jS941YYZZjmCSrHwvX3QjiC

depends on volts/clocks. stock it should be the same as the tdp.

what error does it give? OS, driver/sdk versions? reaper version?

What should I overclock a 6950 to?
what ratio is the memory supposed to be from the core clock

saphirre trixx sucks balls whenever i set manual fan control it changes for a few seconds to my trixx setting then it reverts back to the cards default setting what would that make your memory clock? i took core*0.8 * 2 (ddr effective rate?) and got 1464 if thats your mem clock then using that ratio doesn't get me any more khash than the stock ratio of memory to gpu which is 800/1250 = 0.64

tacotime, thanks for this guide!!
I tried mining with my 7970, but I can't make more than 550kH/s (with core:1050, mem:1600). I've tried reaper and cgminer with tons of different configurations.
I use Windows7 x64 and Catalyst 13.1 - might this be a problem? Should I use Linux? A different AMD driver?

RAM REQUIREMENTS ON-MOTHERBOARD The equivalent amount of system RAM as for the sum of all the vRAM used by the GPUs is required when mining with reaper. For instance, 3x 5970s mining with thread_concurrency values of 8000 each would require 3x 500MB = 1500MB system ram (plus additional RAM for the OS). The memory requirements for 7xxx cards are also higher because of larger thread_concurrency values, for instance a thread_concurrency of 24000 means 1.5GB system RAM per card is required.
You shouldn't need a lot of RAM for cgminer, it offloads it to the GPU unlike reaper which for some odd reason keeps it in the system RAM. reaper is coded really sloppily while cgminer is pretty immaculate. So I am trying to figure out how much memory will I need for two rigs, mining only with cgminer: First rig: 4 x 5870 and 1 x 6990 with 2GB RAM already on the motherboard Second rig: 4 x 7970 ......................with 2GB RAM already on the motherboard Can you give me an estimation? Thanks.

As it says in the guide, use a ratio of 0.57 1050 MHz core / 0.57 = ~1840 MHz RAM clocks; you are only using memory clocks of 1600 MHz. The only way you can hit 1840 MHz RAM is by overvolting the RAM in afterburner. Try instead 950 MHz core / 0.57 = ~1670 MHz RAM clocks, you should get over 550 KH/s with less heat ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Foi49.tinypic.com%2F534dwg.jpg&t=665&c=5kYn2Z_12ch2bQ)

Thanks. 2GB for the first rig is fine as long as you are only using cgminer. With the 7970s, you're going to want to use reaper to achieve the highest hash rates at the lowest possible power consumption. You will need ~1.5 GB * 4 = 6 GB + 1 GB system = 7 GB RAM minimum. Although, you can use 2 GB and cgminer if you want, I just overall much prefer reaper for 7xxx series. 8 GB of RAM is only $40 now, so.

OK Taco, thanks a lot.
With 7970 I achieved around 565 Kh/s with cgminer. I will try reaper if needed. 8GB, got it.

As it says in the guide, use a ratio of 0.57
I used the exact same settings as in your screenshot (core:1015, mem: 1760, same litecoin.conf), but I only get ~430kH/s with Reaper. Which version of Reaper are you using?

that 0.57 ratio at stock only seemed to net me 1 or 2 more khash if cgminer is displaying right

Remove "vectors 1" and try again.
