Hello
 
with a 1080 SC ACX 3.0, I have an Open CL score with Realbench lower than with a 1070 SC ACX 3.0 (1080 : 73 000 // 1070 : 94 000)
Looking at GPU-Z, I see that it is a bios that I can not find on this forum, and the memory frequency is 1251mhz (instead of 5005 mhz)
 


I flashed with the older bios available on this forum (86.04.3b.00.82), reinstalled the Nvidia driver, the memory is at 5005 mhz, however the type of memory is not recognized, the bandwidth increases from 320 to 160, and have an even lower Open CL score (12 000)

the problem must come from bios, I think

What can I do ?
 
Thanks

Yes I saved the bios, and I re flashed
Ah that's normal for the "1251 mhz" then

Why the bios (86.04.3b.00.82) proposed on the forum does "not work", and indicates 5005 for Memory and the one I have of origin is not indicated anywhere) ?
Where could my performance drop come from ?
 
Thanks for your help

I used the .exe provided by EVGA (archive available on the topic in question)
I tried with different drivers and same result

On the other hand, it is normal that in load, the software of monitoring (like Aida64) indicates 2502mhz for the ram instead of 10008 mhz ?
There is a way to know if the memory is 10008 in load ?
 
Thanks

 Checked with CPU-Z, it's 5005 mhz;)
 
It looks like the result is good for the GPGPU of Aida64 ?
 


Will the decline in Open CL scores come from Windows patch since January (to fix the Meltdown & Specter) ?
In December, I had a better score for the 1070
 
Thanks

No, I do not have one
I have to reinstall Windows 10, I'll do a test without Cumulative Update, and I'll see
 
Thanks

For bios, I just updated the Management Engine firmware
I have to reinstall Windows for other reasons ;)
