ASUS Z77 Motherboards - Official Support Thread

[Raja@ASUS]

@ Raja

P8Z77-WS question:
You said "In which case mux is on 16 CPU PEG lanes, to each of those slots." Does it mean that if i want to run sli/crossfire it doesnt matter which slots i use? Do all the combinations will give 2times x16?

Check the manual for lane allocation under various loading conditions, it will tell you which slots stay at which bandwidth or should. AFAIK when any other slot is loaded, each slot will give a maximum of 8x. The only two slots that can do 16X are _1 and _3, but only if you are running ONE card only, dual cards or more and its 8x.

When I read the manual i can't really understand what it says, its so confusing and i think its something wrong, thats why i ask for your or asus help with that. Then the P8Z77-WS is advertised as a board that can do 2times 16x - see asus official specs for that board it says dual x16.

Send an email to ASUS Support for your region they should be able to clear it up and change any typos in the specs.

Hello Raja,

are there news about the HD6950/70 UEFI fix for all concerned boards?

tia, BR!

Hey, it is nice to see overclocking still going on after so many years Thanks Raja and the rest for your support on these forums and keep up the good work

See my reply a few posts back, might help you.

Hi, got my Sabertooth Z77 together today and on firing it up I get RED CPU LED and a constant beep. Disconnected nearly everything and still get the Red CPU LED, beep went away. From computer panel I only have the power switch wired. No Ram, no Cooler, no Vid Cards, no Drives etc.
Using a Corsair 750 Watt PSU which I've had for about a year.
Intel Core i7 3770
Sabertooth Z77.
Noctua NC14
Bios 1015

Would greatly appreciate any help. Saw a similar post on older motherboards and Raja mentioned trying one stick in 4th slot - that didn't do anything for me. Also - I updated to latest UEFI before I ever powered up. Seemed to go successfully.

So i've never seen anything on screen. Freaked out and powered off by holding down power button on all my attempts.

Thanks!

Which DRAM are you using?

Check the CPU socket for any bent pins, clear CMOS with CPU removed, remount and try again with a single memory module.

The fix is implemented and undergoing validation, but we have two UEFI updates in the piepline that will come before it. So I don't have a firm ETA, just confirmation that a patch is going to be released.

@DEFLORATOR

Have you tried with gpuz or ccc to see if your cards run as pci-gen3, x16 or x8?
If you do that, could you please show us some screenies?

Here are my screenshots.
My Archon doesn't allow me to install 7970 into PCI-Ex16_1 slot, so I had to use PCI-Ex16_2.
According to GPU-Z and HWiNFO64, PCI-Ex16_2 with 7970 installed is x8 Gen3 slot (even though PCI-Ex16_1 is left empty, PCI-E_2 is not given all 16 lanes).

LSI 9565 (native PCI-Ex8 2.0) is installed into PCI-Ex16_4 slot.

Have you tried it in slot 3 yet?

[DEFLORATOR]

Have you tried it in slot 3 yet?

No. But I believe it is x16 as long as nothing is installed in Slot _4.
To sum up I conclude for myself:
1) Slot _4 (black) is Gen3 (there is a typo in manual saying it is Gen2);
2) Slots _1 and _3 are x16 Gen3 as long as no card is installed in the corresponding black slot (_2 and _4);
3) Black slots _2 and _4 are all the way x8 Gen3 even if the corresonding blue slot (_1 or _3) is not populated.
4) CPU cooler can interfere with Slot _1 on P8Z77 WS. Archon doesn't allow me to install videocard in Slot _1 (I can make it installed but Archon's fins will scratch it, so I gave up).

Also, my 4x4Gb Corsair DOMINATOR GT CMT16GX3M4X2133C9 need more VDDR voltage on WS than on Deluxe (1,52 vs 1,5v in bios). 1,5v will not post on WS, whereas on Deluxe it was 100% memtest86+/Prime95 stable. Maybe it's a matter of monitoring discrepancy of both boards and not hardware flaw, because AFAIK P8Z77 WS enjoys the same T-topology as all Asus Hi-end Z77 boards (Raja@Asus pls. confirm this).

PCIe x16_1 and PCIe x16_2 for PCI express x16 graphics cards.Is my setup
P8Z77 WS
ATI Radeon HD 4870 X2 GDDR5 PCIe 2.0

By neo_rtr at 2012-05-30

The way i read it, it is 16@16

[Dredd]

Running PCIe 2.0 though yes? I thought it said 3.0 @ 16x/16x on the spec sheet?

So basically you've got the same bandwidth as PCIe 3.0 @ 8x/8x

[neo_rtr]

This come up just the other day.

Wait. I think you you messed everything.
There are two PLX chips which HWiNFO showed: PLX 8747 (located on WS, GEN3) and PLX 8647 (4870 X2, GEN2). These are different chips, and different generation (Gen3 and Gen2).
So you have 2 Radeon 4870 X2 cards, right? And you installed them into Slots _1 and _2? So the total number of RV770 chips is 4?
If so, your cards are given only x8 lanes each, not x16 when installed in slots _1 and _2. But each RV770 chip is given x16 lanes through PLX 8647 which is located on 4870 X2, not WS.
Honestly I don't think that your configuration is optimal, cause the latency isn't good there. See, RV770 -> PLX 8647 -> PLX 8747 -> CPU System Agent, that's how signal is routed, and latency is added at each interim silicon.
At least try to rearrange the cards, and use slots _1 and _3, not _1 and _2.

[neo_rtr]

@DEFLORATOR
Well I emailed Asus support and the reply I got was that I should use slots 1 and 2

Then they are mistaken.

[neo_rtr]

I might do that. Just to prove a point.
However.
As the rig is water cooled, the time and effort to remove the VGA cards and move them a slot is equivelant to, buying a new gtx 680 Hydro and be done with it.
I might do that, However i can not spare the time to do it this week.

Have not seen it before

same here... it just came out just now, and i even don't know where to disable it

[neo_rtr]

I run a quick test with sanctuary 3 or 2 GPUs enabled. I got exact same results.
Did not looked at it any more. However i google it with out any hits.

[p3gaz_001]

i need to disable it since it draws v from cpu!! .... don't know where to press against all the bios, i'm getting mad!!!

On the Maximus V Gene can someone tell me which USB ports on the back are connected to the Intel and which ones are Asmedia, specifically are the USB 2.0 ports native?

Any blue ports will be USB 3.0.
