Ok, I haven't fully read all of your post and also I am a bit of retard so please bare with me
You have 2 different R9 290, one Power color and one Sapphire?
MSI (hynix memory) - to be RMAed
Powercolor (elpida mem) - unlocked
Sapphire (elpida mem) - locked
For the Powercolor with 290X Bios you see no improvement, but with the Sapphire R9 290 with 390 BIOS you see a good improvement?
Powercolor - small gains after unlocking in firestrike. GPU-PI bench is around a couple minutes better than my MSI (again, the sweetest card that I have. Just shy of fyzz's)
Sapphire and Powercolor show no gains going for 390/X bios. MSI does show some gains for the said bios.
What kind of Sapphire R9 290 do you have, reference PCB and cooler? (Out of te box I mean)
All ref on water (not yet completed though. Can't find me a block) but testing was done on water. Swapping works.
Could you post the 290 BIOS version and 390 version you have been using?
Go pick 390/X INSANITY BIOS for the 290/X.
I believe I have Hynix memory on my as well (I will check later today), but mine can't OC to more than 1450 Mhz. So how did you get it to 1700 Mhz, I haven't seen that on a 290. Was that after or before BIOS change?
Your previous screen shows elpida.
Could you run the test with the Sapphire R9 290 and R9 390 BIOS with the same CPU and compare the results?
What about temps and cooling?[/quote]
Will do that in the next days. Board just died.
GPU-Z pictures states Elpida, so I don't have Hynix then.
No point going for the 390 BIOS then?
Doesn't hurt to try.Edited by mus1mus - 11/4/15 at 1:14pm
