My Dual Harper - Asus Z7S WS living review *56K warning*

[shanems3]

Installed my Thermalright HR01-X coolers (thanks jcool) today on the Asus Z7S.

Now the system won't boot
Diagnostic card says F.F. (with dots)

ouch, thats what i got with incompatible CPU's, the cpus are not booting.. check all connections and reset bios..

[shanems3]

1.26 Vcore
These L5410 E0 have not a voltage range they operate, they are 1.212 V
Will try 1.30 later ? You think I can go higher ?

are you watercooled?? whats your TJmax and current temps?

Straight to FF without anything else?
Uh-oh.. that's what my dead one did no matter what
See if the Thermalrights are maybe causing a short or bending the mobo too much.

F.F. stands for double-f'd...

I had this before I bought my EPS power supply so it could be related to a miss-configured or poorly connected power cable, but also I figured out I had my memory in the wrong slots! Try taking out all your memory and see if you get a different status code, if you do, put just one module in nearest the northbridge, that worked for me and it was then I figured I was populating the memory slots from left to right, and it should be from right to left!

I've tried several videocards and different memory configs.
Doesn't work , still F.F. on the display and no post.

[jcool]

Jaco isn't a noob dealing with this hardware, so it's not the wrong memory slot, psu not connected etc. Must be either the coolers causing a short or the mobo bending too much.. I don't see how you could have killed it though just by installing the new coolers.

Did you mount them in a case where they are mounted to the mobo tray?

[Jaco]

jcool , I'm not using a case. I have these verax backplates . No motherboard bending at all.

[shanems3]

try swapping the cpu's around, see if CPU0 is dead??

[STEvil]

are those backplates metal? might be shorting out.

[Jaco]

The backplates are not conductive plus I have been using those for the last half year without any problem.

I have removed cpu1 but no improvement. Display shows F.F. ,nothing else.
I'm going to swap the cpu's and try my other cooler again.

Doesn't look very good, I have a feeling the board's dead

[Movieman]

pull battery, and elec cord, reset CMOS?

[Madman666]

are you watercooled?? whats your TJmax and current temps?

Delta Tjmax @prime = 25C, So temps according to Coretemp with TJmax at 75C = 50C.
Intel published the Tjmax of the L54xx even at 70C (I cannot believe that)
But at idle with a room temp at 19C, the coretemps are 30C (delta Tjmax = 45C) with Coretemp, TJmax at 75C. Sounds acceptable, however I understand the temp probes are not accurate up to 50C.

And YES, I'm my rig is watercooled.

Now back to testing, I tried 1x 2Gb Fbdimm, no change
I tried Vcore 1,26 and 1,30V, no success.
I have my memory cooled (runnning at 50C), my NB cooled (90mm fan).
I think it's the memory.
Unfortunately I don't know anyone with 800Mhz FBdimms to test, so for the moment I'm stuck ;-(

[drewhemm]

Intel published the Tjmax of the L54xx even at 70C (I cannot believe that)

I can believe that. Only when I set my Tj. Max to 70c do my CPUs report virtually the same idle temperatures as my idle GPU, which is what I would expect as they are in the same water cooled loop. I thought the temperatures looked high with Tj. Max at 80c as they were showing in the 40s and my office is cold. If they were really in the 40s then they should be pulling up the temperature of the GPU. The temperatures are also now in relative agreement with Asus PC Probe...

This is the reason I went with the 50W CPUs...nice and cool and cost-saving. It's a shame you haven't been able to get the same results with the L5410s - I guess it's too late to change them for L5420s?

[Madman666]

Just discovered when awaking from S3 Sleep the bios is reset to default ?!?
My FSB is reset to 333 etc..
Can anyone confirm having same issue ?

[shanems3]

pc never sleeps, it always crunches, so cant tell ya if thats true..

[jcool]

Same here.. S3 is for losers

[Jaco]

I'm afraid my board is in a deep sleep . Hope i can wake it up somehow ...

[Mr_Slinky]

S1 S3 who actually used them?

I'm afraid my board is in a deep sleep . Hope i can wake it up somehow ...

If you kiss it and mean it, she will come back to life for you just like Snow White did for the prince!

[Madman666]

Just testing , you all passed, nobody is sleeping
I must have been...sleepin'

Hello.
I'm totally new to Xtreme Systems. I just started my education as a Constructing Architect. We work with CAD and BIM, and i needed a new system that could handle the workload of running up to 3 3D programs at once. This is how i came to XS. As you can see in my sig, my system is similar to some on this thread. I tried to boot for the first time last week but got the same F.F. code, as Jaco gets, on the diagnostics card. Then i found out that it was cause my 1st power supply (NQ giant reactor) only had 2 power connectors for the MB. Ok, changed it to the Tagan 1100-BZ. Now i get past F.F. at least. It goes to F.0. and then 8.0., but gets stuck at E.1. and the manual is absolutely useless when it comes to the diagnostics codes and ASUS is just as useless when it comes to replying to the mails you send them. My MB is Rev. 1.03, so it should support the Xeons(E5420). Does somebody know what these codes mean?
I would very much appreciate some help.
How do i register for WCG? Would very much like to contribute to such a great cause. My system wouldn't run 24/7, but it normally runs about 8-10 hours a day, if that would help?

[D_A]

Every hour spent running helps.

[jcool]

Hum.. can't recall what E.1. is really.
As you already realized, you need both the 8pin 12V and the 4pin 12V connected to the mobo if you have 2 CPUs in it, or it won't start at all.
Now, try removing all your memory except 1 stick in slot 0 (the one closest to the northbridge/cpu sockets) and try again. Also clear CMOS and try another GFX card if you have one.

[Movieman]

asus Z7S ordered also with 4x1 gig Kingston HyperX DDR2-800FBDimms
X5460's waiting to go in it and WC all ready for this.
Now as long as they don't ship me a dead one..

Ok, so what does that mean? Is there a problem with the keyboard or mouse?
Like i said, i'm totaly new to this. Will try to clear CMOS and only install one ram module and yes, i have all 3 power connectors connected, 24pin 8pin 4pin. Thanks for the advice so far.
