ASRock Fatality Z97X Killer LGA 1150 board works with 6 cards on risers in Windows 10. Can only get 5 to show up in Windows 7 (Code 43 on the 6th). Set all three PCI-E x16 slots to GEN 1 in Bios. Haven't tried adding the M.2 slot PCI-E adapter yet.

Hey guys, after sleepless night I really need your help.
Setting up 2nd rig: 6 cards mixed brands. One was even "like new" condition and I found out somebody played with bios already, It is GB Aorus XTR 8GB and its LED is not working and bios timings were changed.
Can anyone post his original BIOS for this card? If it helps I will be really thankful.

Also second problem - was flashing BIOS and PC crashed or freezed and card which was in progress seems to be dead...PC just never turn on with that one. It is GB Gaming G1 8GB. Any idea what to do?

Thanks!
Do you use patcher before flashing any card?

i have 2 gpu. 1.Asus gtx 1070 rog strix.  2.Gigabyte gtx 1070 windforce. Gigabyte gpu working normal on riser. But Asus is not working. But led is on.  How to solve the problem?

I'm new in tuning AMD Bios and read a lot. I have a new Pulse RX580 4G D5(Sapphire type 11265-09-20G). The SRBPolaristools shows me that there are 2 different 4GB-VRAM types - 1st is a  EDW4032BABG (Micron-Elpida), 2nd is a H5GC4H24AJR (Hynix). Now occur the 1st question - why is that a 4GB only card and no 8GB card? ...and which VRAM should be adjusted for tuning - both or the Hynix only. Saw in some videos adjusting sometimes only the 1st memory and sometimes the 2nd memory, but never both. Thanks in advance for some helpful hints.

idiot of the day is here

I just built my first rig today and placed the motherboard on top of a conductive stainless shelf.. tried to power on for like an hour wondering what the hell is wrong with my build.. It was powering on and off at one point too... Eventually figured out and got it working but how bad is this? lol System is running fine but I am wondering if I made any damage to the board. This is like the dumbest thing ever smh

Both are RX 580's 8G. The Red Devil has Samsung, and the Red Dragon has Hynix.

I have one perif plug on my PSU. And 4 SATA plugs.

So you're saying to ignore the SATA plugs entirely. And only use the Perif 6-pin plug? And if in that case, the most I can get out of that 750W PSU is two (MAYBE) three molex connections (on the string of 4)

If I was going to use the risers with 6-pin, what exactly is the cable I need and is it a 6-pin perif cable or a 6-pin sata cable (I'm talking about the labels on the PSU)

I have two EVGA 750W.

Any links to the actual cable would be super helpful...

Most non-ETH altcoins are a lot less sensitive to memory latency issues than ETH and it's offshoots.

 GTX 1080 and 1080 Ti both work quite well and efficiently on ZEC, among other options.


 I doubt we are going to see much if any more hashrate out of the mining-specific cards vs their consumer varients - but dropping all the video circuitry and disabling the "video output" parts of the GPU die should result in substantial power savings, I could see 20-30% less power used at the same clocks as a result (which would be somewhat better than TheStilt managed on his "no undervolt" version of his R9 290 BIOS, but he didn't disable ALL the video capabilities and the video output stuff was still on the board).

 Pricing numbers seem to still be up in the air and conflicting - but IN THEORY these boards should be lower priced, though being smaller production numbers might limit the savings some.

 I did see mention somewhere that EVGA might be one of the "partners" after all - which gives me some hope for us "small fry" having access at a fairly reasonable price, given their direct sale policies.

Can't modify bios...not sure why but seems locked. Used latest driver but then i can't use  GPU's so i went ahead and used the trick someone wrote here to use a mix of old/new driver and install from the device manager. Works fine but still, can't modify bios and can't use WattTool...anyone got an idea on how to fix that?

Ok, so I have both 006 molex and 006 6 pin risers. However, if I don't use the SATA adapters, the only cable I have available is a 6-pin (perif) to 4x molex string. And I can only use 2 of those 4 molex for safety, how can I connect the other risers? I have two EVGA 750W G2's. They each have 1 perif and 4 Sata plugs on the back.

So I'm assuming I need a 6-pin sata (that plugs into the PSU) to 6-pin that plugs in the riser, but this is the issue, where on earth are those cables sold. OR I need a 6-pin sata (that plugs into the PSU) to molex, and again, can not find cables for that.

Unless I'm just totally blind.

It's really quite straightforward:

Sata connectors are rated at no more than 54 watts.

Molex connectors are rated at 132 watts.

I'm not sure what the 6 pin is rated at but I think it's more than the Molex.

Therefore if you have any sata connectors in the cable to your riser, then there is a risk of overloading the connection.  It doesn't matter if the sata connector is on the riser or in an adaptor cable.  Same problem.  Solution: Do not use the ver 7S risers. 

Recommended: ver 006C (6 pin) or ver 006 (molex)

Of course lots of people use the sata type 7S and lots use a sata to molex/6 pin adaptor.  But the fact is that the connector is only rated for 4.5 amps vs 11 amps for the molex for example.  It will still work and most likely it won't get hot and catch fire.  But nonetheless it is much more likely to than the others.

Should I mine in a pool?

Okay so no need for bios mod. What about voltage mod? Any news?

It seems that there is no bios mod no undervolt no overclock. We just plug and play and mine. That's it?
