No bios flashing or anything.
About 1555 khs across all 5, stable and running great, highest temp is 53c.
Sorry, no wattage figures yet, I ordered a killawatt and it will be here wednesday. May try Bios flashing and see if it helps at all but Im pretty pleased with where it is at now. I've ordered several different 750tis for comparison,
3x PNY GeForce GTX 750Ti OC VCGGTX750T2XPB-OC
2x ASUS GTX750TI-OC-2GD5
2x MSI 750 Ti 2GB GDDR5 OC, TWIN FROZR - N750TI TF 2GD5/OC
I want to see the best hash I can get out of the 750tis without the PCIe connector.
The one card that is hashing higher is the one that is plugged into the 2.0x16 slot. I've seen another guy test this and you do see a ~10-15 khs drop using x1 versus 2.0x16 or 3.0x16.
