Excellent to see this thread. My P8Z77-V PRO arrives tomorrow. This is my first foray into the Intel world in 15 years (when I was 15yo). Does the V PRO ship with the latest UEFI firmware or should I upgrade immediately after getting it in hand via usb?

[Raja@ASUS]

Could have been an update since, so check and if the shipping build on your board is older, and if need be update to the latest:

So, this BIOS is working with Saber Z77 too?

Is there any way that I can set tRC timing in Asus motherboard?
I have a kit of Crucial RAM(Tactical Elite 4GBx2 1866 CL9) that's been tested running fine at 2133/9-9-9-27 with tRC=47 on Gigabyte Z68 M/B but wouldn't run stable on my P8Z77-v Deluxe and my previously owned P8P67 Pro.

If you increase tRAS it will create a similar effect to having a larger tRC. tRC at the bare minimum is tRAS+tRP. If the tRC value is smaller than tRAS+tRP the IMC should auto default to a larger value. For the Z77 boards, I will ask if we can have it unlocked, but will need to check the static values first.

@raja is there an m5e in the pipeline?

[Eldonko]

I sure hope so.

That's awesome! Looking forward to seeing new Firmware with adjustable tRC.
By the way, i tried several combinations of tRAS and tRP to make tRC=47 but it's unstable or no boot.

No promises, we will test first and if no gains for performance then it may not be added.

If it can run Crucial kit that I mentioned at 2133/9-9-9 like on Gigabyte M/B can then it's definitely performance and reputation gain.

Not neccesarily, because every time a row needs to be closed (page miss) the IMC will have to wait 47 clocks - (tRAS+tRP) before the next row can be latched. On every page miss, it is like adding X number of clocks to tRCD before CAS

What I meant was Gig M/B can run it 2133/9-9-9 with tRC adjusted to 47 while Asus can't do it at all "probably" because tRC adjustment is not available on Asus M/B.
I think it's better to have that option available to make the M/B less "picky" with RAMs.

Just my thought tho. I've seen people reported running it on MIVE just fine.

I understand what you are saying, but there is not always value in having timings adjusted so far even from a raw performance perspective. It depends what you deem valuable. It may not be tRC that is causing the instability anyways, so that is why I said we will check first and it is also likely why it may have been left out due to not adding anything. If the margin between needing a high tRC versus a slightly lower clock frequency are not large enough, the additional delay to tRC is of no real benefit.

Okay, let's see what you find about instability with this Crucial kit. The Part Number is BLE2KIT4G3D1869DE1TX0.

Will test with the kits I have here from Crucial, GSkill, Corsair etc. If no change, or the change is too small then no point.

Just in time

Recieved M5G last night along with much talked about Samsung ram to test along with GTX2 and 2200Mhz Adata. Just awaiting Ivy Bridge release to begin testing and ease back into the benching game

Cool, look forward to your results

Just ordered a P8Z77-M Pro, hope ill be happy

hello,

i had a blue screen under windows after 5 mins of 5ghz stress test. since then i cannot overclock, even after clearing CMOS, i tried to roll back bios to previous version (801).
no effect... my system is working fine it's just that it does not take any mutliplier modification into acount anymore.
just as if my cpu wasn't a K anymore...
(Z77 sabertooth + 2700k)
i'll try your new bios and keep you posted

having post code 55 come up a lot when loading tight preset memory profiles on the M5G with sb, any ideas?

on the latest bios 0880.

Means the IMC is probably topping out with the DRAM timings you are using. Use looser DRAM timings. Start off with Latency Boundary set to 14 and work down. If you get "55" at Latency Boundary 14 the IMC is tapped, though you might get around it with CAS, tRCD and VDIMM.

Shouldn't known stable P67/Z68 timings be similar to Z77?

Latency Boundry is all ready at 14, I got it to work by loading the loose PSC profile and keying in the tighter primary timings I was looking for, and viola boot, I think it has to do with auto setting secondary or tertiary timings a bit to tight when loading the preset memory profiles.

however I did have to loosen my timings on PSC to 7-11-7-27-1T to get them to boot/bench stable.

6-9-6-20 on BBSE is not happening and unfortunately no hypers to test on this platform with sb cpu atm, but not expecting miracles.
