Broadwell help?

[Arachnotronic]

Hi all, bought a 5775c for my ASUS Z97 Sabertooth Mark 2. Sadly, no matter what I do, I cannot get the iGPU to work -- the "VGA_LED" light is always on when the Broadwell chip is in there with no dGPU, but all is well when I have the Haswell CPU in there (no dGPU) or the Broadwell CPU w/ a dGPU.

I am using the latest BIOS, and ASUS says that Broadwell is supported. Any and all help would be appreciated.

Did you see this?

"Full support of the new CPU requires VGA driver version 10.18.14.4206 or later"

What output are you using? HDMI?

Tried HDMI and Displayport, can't even POST

In bios under primany display settings, can you make sure the line that says ipgpu is set to on? Even if you have to do it with dgpu installed, & then pull it & see if you have video when you power it up next..

Um, I can give that a shot. Will report back once I have tried this.

I had the exact same problem back in September on my ASUS Z97 Gryphon when I moved from a G3258 to a i7-5775C. Even though I had the latest BIOS (version 2401 at that time) that listed support for Broadwell it still didn't work. I ended up having to install a dedicated graphics card and re-flash the BIOS with the 5775C installed. Your 5775C works just fine, the BIOS or CPU microcode is screwed up and not allowing the iGPU to initialize.


Before I re-flashed the BIOS with the 5775C installed I looked at the CPU information in the BIOS with the dedicated graphics card installed. The microcode version was missing and a few other pieces of information were wrong. Since then ASUS has released 3 more BIOS revisions (for my board at least) that have corrected this problem and a few other issues. Broadwell was really rough going for me until BIOS version 2501 under Linux. I would experience random hardlocks all the time under Fedora 23 regardless of kernel version, yet Windows 10 would run for days with no problems.


Long story short makes sure you are running the latest BIOS from ASUS, and re-flash with the 5775C installed. Even though they listed Broadwell support it still was horribly buggy. Not sure if the fault was on Intel or ASUS but to this day neither would admit there was a problem and blamed each other for the problem.

Welcome to the forums and thanks for that information. Hopefully it saves Arachno from slashing his wrists

@ V4004

Interesting. Thanks for sharing.

@ Arachnotronic

Congrats on your new toy. When are you putting your dGPU up for sale?

 

[tweakboy]

DO a BIOS flash too! possible fix,, thx gl

Thanks for the post! I just tried this and sadly it didn't work for me

This CPU is going on eBay, going to buy a SKL to replace it. ASUS will not be getting my business this time around.

I feel like ASUS is all marketing, no substance. I don't know who to trust when buying a motherboard, but it sure isn't them.

 

[Magic Carpet]

Maybe the ME part didn't get flashed right or something. Hmm.

I used to buy basically nothing but ASUS and would recommend them to friends and family. My experiences lately have been downright poor...flaky X99 board, Z170 board with issues that did not get fixed until a BIOS update 3 months later, and now this crap.

They will not get my money for a very long time.

Speedshift isn't supported yet on their mobos either. I am very happy with MSI this time around with full support.

Sorry to hear about your issues with ASUS

Thanks...this is really a bummer because I've been using ASUS for more than a decade, it was good to have a "go to" motherboard vendor. I have had good luck with ASRock and outside of motherboards MSI.

Anyway, thanks for the help everyone but at this point I've wasted far too much time on this and am just going to cut my losses.

Hi Arachnotronic,

I am sorry about the cpu issue.
The good news is that your cpu works with this motherboard. I checked qualify vendor list for you.

You have to do a Flashback with BIOS 2401 with video driver 10.18.14.4206 or later. You are good to go.

BIOS download here.

http://dlcdnet.asus.com/pub/ASUS/mb/LGA1150/SABERTOOTH_Z97_MARK2/SABERTOOTH-Z97-MARK-2-ASUS-2401.zip

You can read the manual to find out how to do the flashback on page 2-11 (section 2.2)
http://dlcdnet.asus.com/pub/ASUS/mb/LGA1150/SABERTOOTH_Z97_MARK2/E8886_sabertooth_z97_m2_WEB.pdf
Just make sure you copy the SABERTOOTH-Z97-MARK-2-ASUS-2401.cap file to root directory of flash drive.

For AM3+ ASUS has been the only vendor to make truly solid boards for high-wattage CPUs and overclocking (the true 8 phase Sabertooth and Crosshair boards in particular with the 6 phase boards also having good results). But those came out in 2011/2012 so things must have changed.

AsRock, by contrast, has a very poor reputation on AM3+ due to poor-quality heatsinks, low-quality MOSFETs, and high socket temps. Gigabyte is known for having BIOS bugs (like UD3P 2.0 that won't post above a 22 multiplier) and things like undisclosed power limitations (UD3P 2.0) that cause board throttling. That board is also marketed as being an 8 phase board but it's a doubled 4. MSI released a "12 phase" board that was really six phases with a doubler and even a tech review site (not Anandtech) praised the board for having the most robust power delivery system on the platform due to its "12" phases — only to have the board flop in overclocking. It was soundly beaten by the first generation Sabertooth.

Sketchy marketing, sketchy BIOS, sketchy build quality... all these things are avoided in AM3+ by going for a 6 phase or better ASUS. So, I wonder what changed with the company that has caused them to sound more like Gigabyte in terms of BIOS quality.

 

[Arachnotronic]

Tried to update to BIOS 2401 (older than 2702 that I had), but it would appear that this board is bricked after it said "Update Succesful!" Damn.

 

[Azuma Hazuki]

ASUS has never, not once in 15+ years, given me trouble. I also buy from Gigabyte and MSI at the low end, but ASUS has been my faithful, trusted source since I started building computers back in high school, literally half a lifetime ago.

Maybe the problems are on the high-end boards? I've never gotten anything more than a B85 or H81 from them recently.

 

[DrMrLordX]

*sigh* more Broadwell-C nightmares. If it's any consolation for the Asus fans out there, the Maximus VII Gene supports it, apparently.

 

[Magic Carpet]

To be honest I believe the OP's Sabertooth also does. Not sure what he does wrong, though.

 

[Arachnotronic]

Yeah...this chip should not have been released. Or maybe ASUS should properly test these CPUs before claiming that they are supported. Inexcusable.

 

[Shaun_Brannen]

It could just be a DOA mobo or CPU. It happens, especially with motherboards, although the RMA rate is a lot lower than I'd thought (typically 5% or less, it appears).

CPUs have got to be <1%. I've never even heard of a DOA CPU. They die on rare occasion, usually in overheated laptops, but that's basically it.

CPU work(ed) fine in this board, but iGPU doesn't. When I popped in my Haswell CPU, iGPU worked fine.

Remember I had been using this board with a Haswell for nearly a year.
