L4 cache only helps in memory-intensive workloads, such as gaming, compressing and decompressing, certain types of simulation... But it does little to nothing to those workload more calculation-intensive.
Most single-threaded benchmarks out there are from the second group. And those memory-intensive workloads tend to take advantage of multi-threading.

For dx11 gaming the 5775c should still be better than Broadwell-E, and in dx12 the extra cores put Broadwell-E the first place, although the 5675c and 5775c shouldn't be that far. It has been proven memory plays a crucial role, in such a way a 5775c can take as many draw calls as a 5820k.
I'm so impatient for the new 3dmark dx12 benchmark, it will be funny to destroy those 6700k and 4790k heavily overclocked xd

Has anyone in the Broadwell-C Club tested 4K over the motherboard's DisplayPort?

I ask because I finally upgraded my ASUS Z97-WS to a Core i7-5775C and was surprised to see the IGP is now driving my 4K/60Hz monitor at 30Hz on both the DP and mini-DP ports.

The same cable/mobo/monitor worked fine with a non-K 4790 and always drove 60Hz on both the DP and miniDP ports.

I see that the BIOS of the Z97-WS seems to have only received one update for Broadwell while other Z97 mobos from ASUS/ASRock/MSI/etc. appear to have had several updates!

That being said... the Core i7-5775C is very cool and rock solid and the 30Hz output is sharp (but annoying to use).

I'm itching to overclock but am looking to get this 4K/60Hz issue resolved first.

So, has anyone else tried driving a 4K/60Hz monitor with their BDW-C?

Thanks!

ASUS has a messed up method for BIOS updates on Broadwell. Here is how I did my update:

1. Clean windows install
2. Update Intel ME driver manually
3. Download ASUS's own updater app: http://dlcdnet.asus.com/pub/ASUS/mb/LGA1150/Z97-A/BIOS_updater_for_5th_Intel_Core_CPU.zip
4. Update your bios to the latest with the app: http://dlcdnet.asus.com/pub/ASUS/mb/socket1150/Z97-WS/BIOS/Z97-WS-ASUS-2403.zip
5. Restart

You should see your Intel ME version getting updated in the BIOS. I'm suprised your IGP even works. I got black screen on the mobo's outputs before updating like this.

(This was the method that works for me, but I must put it here, do at your own risk!)

Thanks, I just tried your steps and flashed from Win10 but the result is no different than before -- still 30Hz. wackosmiley.gif

I previously used the USB Flashback method (a number of times) with the same result.

[ I'm getting really good at paging through the BIOS and restoring my preferred settings ]

The Z97-A appears to have had 5 additional updates since its initial Broadwell BIOS while the Z97-WS has had none.

The ME engine on the Z97-WS 2403 BIOS is 9.1.25.1005.

Also the Z97-WS BIOS's Broadwell microcode revision is "D" (0x0D).

There are newer microcode updates for Broadwell that solve some fatal issues so that's another thing ASUS needs to fix.

Here's a blurb on the important Broadwell microcode fixes:
Quote:
ASUS has an initial Broadwell Microcode, but there is a critical bug with the 5775C and a few other Broadwell chips, fixed if the CPU microcode is updated to 0x12 or higher.
This was reported by intel as Errata BDD86/BDM101 in September 2015
http://www.intel.com/content/dam/www/pub...spec-update.pdf
The latest ASUS BIOS as of this posting only had microcode 0x0D, BIOS 2604.
documented:
https://www.reddit.com/r/hardware/commen...75775ci75700hq/
https://bugzilla.kernel.org/show_bug.cgi?id=103351

I checked the BIOS of a couple MSI motherboards and see that they have this high priority fix.

I'm all over ASUS trying to get them to update the BIOS of this mobo because 4K at 30Hz is not easy to use.

But can anyone else confirm 4K@60Hz over a BDW-C DP port?

Sorry to hear that. According to Intel documentations and the 4K iMac, the Iris Pro 6200 should be able to do 4K 60Hz. Since I don't have a 4K display I can't confirm it.

I wouldn't expect too much from Asus support. They're nice, but Broadwell was already a drag for them to support. With the current Z170 boards and the upcoming Z2xx boards they have enough on their plates. Broadwell user numbers are too small for them to care sadly.

I am persuasive and hopefully the Z97-WS being classified as a "server" mobo will result in better customer service. smile.gif

I'll let everyone know how it works out!

i've messed with the UEFItool and UBU before (not flashed my motherboard with the resulting files) and i'm very surprised that asus has no newer microcode updates or anything.
post #308 of 2235
I actually flashed my mobo with an updated BIOS created with UBU.

The UBU tool worked very well and the board booted without problem (with the updates actually applied) but it didn't solve the root problem with the DP ports being stuck at 30Hz with Broadwell-C.

Since this didn't fix my problem, I flashed it back to 2403.

I suspect ASUS has to fix something outside of the UBU-updatable option ROMs in order to properly support Broadwell-C.

Hello everyone smile.gif
A week ago my motherboard just broke down in the middle of a gaming session. I have a asus z97-a(now dead) , 4690k and 980ti. I've now been thinking about selling the 4690k and picking up a asus z97 pro-gamer + 5575c. Anyone tested that board with a broadwell? My goal is to get it to 4.1-4.2 stable oc and I mostly just play on this pc so should be a pretty good setup?

Honestly in your situation, I'd either just replace the board or move to Skylake.
