ASUS Official X79 Motherboards Support Thread

Ok

Because when I see a "SB-E" to 4500 with ram to 2400 9-11-11 best (bandwidth) that "IB-E" to 4600 with ram to 3000 12-14-14

I hope Asus will modify secondary and tertiary timings (when left in Auto)

if you reall want to have nice bandwidth then modify secondary and tertiary timings by yourself

[Leeghoofd]

can you also check eg Superpi 16M, the stock bios setting and your tweaked setting, I get close to no difference here at all over 40K bandwidth. So the bandwidth seems to be superfluous from a certain point (at least for SuperPI :p) Running PhotoworXX confirms this, a 20K incrase in bandwidth hardly improves the score with 300 points... when tweaking haswell and Ivy that score went bonkers, not on X79...

[tistou77]

With SuperPI 16M

With bios 4206: 3m 26.123s
With bios 4403: 3m 38.790s

No real difference

I changed the sub timings and perfomance are come back with the benchmark of Aida64
I still hope that Asus will do sub timings, more aggressive

I'll wait until some bugs are fixed before past the bios 44xx, 45xx

- Disabling EIST/C-States causes Windows to see 1Mhz CPU speed (with unknown ramifications--could be purely cosmetic).
- Random underclocking/throttling under full load for some users.
- RAID Matrix utility inaccessible for some users.

[Leeghoofd]

12 seconds difference is huge. My difference within the same bios, then tweaked/untweaked are not even a 1sec

It's not only the timings then, something else is going on between the two bios versions

Since the CFR Corsair DomGT Plat are of bad sticks I could only play 3k with CFR TridentX in dual channel

4930K @ 5.0GHz
G.Skill TridentX 2800C11 2x4GB @ 3000MHz 12-14-14-35-2T



PS: the same kit just needs 1.65v for that mem speed/timings on Haswell.

[owikh84]

My best quad channel mem OC with CFR:

4930K @ 5.0GHz
Corsair Dominator 2800C11 2x4GB + G.Skill TridentX 2800C11 2x4GB @ 2965MHz 12-15-15-35-2T

[owikh84]

4930K @ 4.6GHz
Corsair Dominator 2800C11 2x4GB + G.Skill TridentX 2800C11 2x4GB @ 2800MHz 11-14-14-25-2T



I am not sure whether the Gflops are correct though. It's still fluctuating quite badly. Just as a reference of highest clocks for 24/7 under water.
Note that the TJmax for IB-E is 95C.

[Shiranui Gen-An]

That's what I'm talking about there! Quad channel madness!

[xarot]

Is the max temp now 95 degrees, I believe in SB-E it was 91 degrees until throttling?

[owikh84]

yes 95c is the max temp for IB-E before throttling.

Keep them coming guys, is that maxmem low?

[ToyTen]

yess +1

[Leeghoofd]

Keep them coming guys, is that maxmem low?

I got no idea if it's low or not, the CPU is near stock frequency. Maxxmem is a buggy benchmark anyway :p

@raja@asus,

Sabertooth 4302 BIOS is buggy with 4930k IB-E. I have 16GB 4x4G, worked flawless before on Sandy Bridge-e. The F/W see's all four dimms, but some how it dropping 8G. It is also seeing both ranks but only showing 8G. I have tried both standard and optimized for memory config (new option as I bumped up from 3501) that didn't help.

The BIOS is complaining about XMP tables being abnormal on channels A and B, but not C and D. I moved the RAM and it still complains for A & B and not change.

[Raja@ASUS]

Without a kit part number there isn't much I can say to HQ or suggest.

[DualCpuUser]

Easy to fix.

Memory is: G.Skill F3-14900CL9-4GBXL, They are by XMP 1.2 (1866/9-10-9-28, @ 1.5v) Although they were flawless also at 2133/9-11-10-28 @ 1.65.

Without a kit part number there isn't much I can say to HQ or suggest.

I need some help here.

Got an R4E with old bios (unknown version)

I bought an Ivy-E

Can i flash the latest bios from rog usb and give it a go ?
Or do i need a Sandy-E prior to flashing ?

[Raja@ASUS]

Use USB bios flashback with the latest uefi version. The flash will take a few minutes as the me will be updated.

It doesnt accept to flash a cap bios file.

So i assume it has an old rom bios loaded.

I downloaded the conversion bios (from rom to cap) and began flashing after renaming it to R4E.ROM
It flashes ok , but uppon restart , it shuts on-off repeatedly.

Do i need a sandy-bridge core at that point to finish the conversion ?

Yes, it appears you do need a SB-E, possibly 9XX (2011) socket CPU. Here is what didn't work for me.
Buy R4E MB
Put IB-E in socket and do the rest..
Clear CMOS
Power board... Nothing, no CPU start up.
When you can get USB 'connect' to power up, a laptop did clear CMOS and power it; but would say CPU locked.
I didn't know the BIOS level (After putting in my SB-E it was 36XX) was. This is a CAP style UEFI F/W. USB Flashback should I WOULD THINK load CAP files.

I tried everything I could think of available to me... NOTHING!!

WHAT WORKED
The only way I got the IB-E up and running was put in a SB-E, Flash to 4403. then drop in my IB-E.

After CMOS reset, powered board was the system able to initialize.

It doesnt accept to flash a cap bios file.

So i assume it has an old rom bios loaded.
