No Ideas?
Well, here's a Dual core Opteron 3350 HE running Two 7750s in Linux; Computer 5824571
My 7750 gave similar times in Mountain Lion, it's 5 minutes slower in Mavericks...

It's a Quadcore, but BOINC does not know, hehe !

And a Turks should need ca. 75 minutes per unblanked AP wu.

I was wondering why I couldn't find a Dual core 3350 HE at CPU World...

...I am wondering how long it should take before I begin to see an increase in my RAC...

Looks like the APs are back. Have you tried anything on your computers, to increase GPU speed? The only thing I can think of is a repair install of Windows 7, but, since both machines are giving similar times it's unlikely that would do any good. I don't think there are any BIOS settings that would help either. There's also not much you can do with the ATI MB App. You can apply some settings to the ATI AstroPulse App though. In the ProgramData/BOINC/projects/setiathome.berkeley.edu folder there's an empty file named ap_cmdline_win_x86_SSE2_OpenCL_ATI.txt. Open the file with notepad and paste the following line in;
-unroll 6 -ffa_block 4096 -ffa_block_fetch 2048 -sbs 256 -hp
Save the file. You don't have to stop or restart BOINC, the next task run will use those settings. If you don't like the settings, just open the file and delete the line.

You can run an AstroPulse task immediately, to test the settings, by sorting the BOINC Manager tasks by Application. Then select all the non-AstroPulse ATI tasks and hit Suspend. Once the AP starts, hit the Resume button.
See if that does any good.

I modified the command line file for both of the AMD machines. I have both of them currently set to receive only Astropulse tasks.

Forgot to ask... is there a way to setup custom location labels?

It's better than it was. No more 20,000 sec runtimes, but, it's still about 2 or 3 times slower than it should be on APs. You could check the GPU Load with GPU-Z and maybe raise the 7750 to;
-unroll 8 -ffa_block 4096 -ffa_block_fetch 2048 -sbs 256 -hp
As long as the Load is not steadily around 98-100% GPU Load it should be OK.

Raising the Priority may help the MBs as well. In the same folder, setiathome.berkeley.edu, there should be an empty file named mb_cmdline_win_x86_SSE_OpenCL_ATi_HD5.txt. Open it with notepad and enter;
-period_iterations_num 32 -instances_per_device 1 -sbs 256 -hp
Save the file. The next ATI MB task run should use those settings.

Hopefully we'll see some more APs this weekend...

BAM! can do it.
Probably all account managers can do it.

These are the MB files that are in the directory. I just wanted to check that you meant the OpenCL-ATi.txt file and I was not missing a file I needed.

Well... Actually... It appears you've installed the version of MB_V7 meant for the older cards. The other one will probably work better, you want MB7_win_x86_SSE_OpenCL_ATi_HD5_r1843. You'll need to shut down BOINC and run the Installer again, using the choices from above again;
Place a Check in the following;
Enable processing AustroPulse tasks r1797
Enable processing MultiBeam tasks r1846
Enable processing AstroPulse tasks on GPU ATI r1843
Enable processing MultiBeam tasks on GPU ATI_HD5_r1843

After you run the Installer, you'll need to add the settings to the ap_cmdline and mb_cmdline files again. Also, delete all the .bin, .bin_V6, .bin_V7, & .wisdom files so newer ones can be compiled.
