After scanning through some previous Seti results and a couple of clinfo saved text files. On my RX 480 Max frequency increases with an increase of the overclock. I haven't tried lowering the clock below the factory overclock to see if Max frequency decreases.

I believe it is different with Nvidia cards on Windows. I've never seen the max clock frequency reported other than 1683 for my 1070s in any computer. That is the Nvidia published core clock frequency for reference Nvidia 1070s. They regularly boost to around 1960 Mhz in normal BOINC operation.

On the board.

OK, thanks. Then that is what is happening. The 1060 is in the lowest PCIe X 16 slot (PCIeX16_3) and is running at X4 speeds. The 1070s are in the highest and middle X16 slots (PCIe X16_1 and PCIe X16_2) and are running at X8 speeds. The shorty card fits .... sort of ... I had to pull the front panel USB 3.0 cable from the motherboard until I get the right-angle adapter.


Which right angle adapter are you getting?
I am interested in knowing that too, I am bending one a little on my ASUS board right now using a 3rd full sized GPU in the bottom slot, and wasn't pleased having to do that. So, if you have a low pro one that would get the clearance for the card, I'd love to hear about it once you've received it and tried it out. Thanks!

Based on the image provided in the link I posted, it looks as low profile that you can get with the plug part. The other option is the adapter that has the male USB 3.0 plug going to flying leads that carries the female part and would let you really smoosh the leads flat at extreme low angles coming off the plug to get it clear of the video card sitting over the top of it. If the one I ordered doesn't fit under the 1060, I will try the flying lead one.

Perhaps the behavior for the Max clock frequency has changed in later releases?
For my R9 390X I always see 1080MHz, which is the Sapphire factory OC value, & I have bumped it up to 1100MHz.
For my GTX 750 Ti I see 1267MHz, the EVGA max boost value is listed as 1268MHz, & it actually runs at 1345MHz without me doing anything.

Message 1878351 - Posted: 15 Jul 2017, 9:47:17 UTC

with a HD7750 oced to 900Mhz, with Boinc 7.6.22 , i always see the 900Mhz on the Stderr.txt

but with the last 7.6.33 , it only show the stock frequency 800Mhz ... because at the boinc startup, GPU is not used and stay at basic frequency .. perhaps an explanation ?

MSI RX480 Armor 8gb OC (factory overclocked at 1291MHz core, 2000MHz memory), Boinc version 7.8.0, AMD driver version 17.7.1, MSI Afterburner version 4.4.0 Beta 12. What ever core clock speed I set in Afterburner is what OpenCL reports as Max clock frequency.
... and still I fear, and still I dare not laugh at the Mad Man!
