I'll keep that as an option but as last option as this board isnt for me and I dont want to break it lol. I'll be calling into my uni to see if I can borrow the heat gun from the electronics lab, the advantage of gettin to know the technician well :p: I'll let you know how I get on, thanks.
yeah i've been wondering like cultie here as well.
my z7s is arriving soon and I've got my IFX ready, but never removed a NB heatsink before :\
ANYWAYS...does anyone know if the
Western Digital VelociRaptor WD3000GLFS
will work with the Asus Z7S board? confirmed?
I got my replacement lying right here. Can try it on the Z7S rig if I get around to it...
I just received two HR-01X heatsinks in the mail. I'm surprised that neither heatsink came with a protective seal or tape covering the polished base. Is this normal for Thermalright stuff? One heatsink has a small 3mm scratch on the base. It doesn't look like it'll affect the cooling performance (scratch is ~2mm from the edge), but it is a flaw. Should I return it for a replacement?
Mine were packaged perfectly.. But no protective tape, that's normal. If the scratch doesn't affect cooling performance there's no need to rma.
I bought a WS Z7S, 8 go ddr2 pc6400 fbdimm and 2 E5420 (from different sources).I haven't been able to boot with the 2 xeons, though I tried 2 PSU :
Enermax mod82+ and antec true power 850Watts :
Nothing happens and the diagnosys tool stays stubornly on FF. :down:
I even tried booting the motherboard outside the case in the eventuallity that the coolers were shortening the motherboard because of the back plate fixation.
I am able to boot with 1 xeon (but it sucks big time :mad:) in Cpu0 (with either of them).
Of course I plugged in the P8 Eps 12v and the P4 Atx 12v and I'm using the Intel stock coolers.
I tried with bios 202 and bios 302 too..
What could be wrong ?
I saw on a newegg review that someone else had the excat same problem I had (and he says E5420 aren't officially supported by Asus, probably for this reason).
Someone asked what the results with only 1 E5420 were.
Here are my cinebench 10 results :

5420's not officially supported ?
Where have you read this?
Specs say : Support Dual-Core Intel® Xeon® Processor 5100/5200, Quad-Core Intel® Xeon® Processor 5300/5400 Sequence
I know jcool's running 2 x E5420 without problems afaik. 3.2Ghz no problem.
(I still have only 1 E5420 in my Asus Z7S so no hands on experience... )
well, it isn't listed in the CPU support list from Asus (it isn't proof, I know)
And I read that here : look at the review of "so_onlocky"
This guy has exactly the same problem I have.
By the way, are there differences between E5420 Slan V xeon ?
I bought 1 in a blue bow saying "Quadcore server"
and 1 in a gray box saying "Server computing".
On one box you can read "support for two socket system and on the other "support for dual processing"
one is version E24859-001
and the other is E24859-002
could it be that ? though they are both xeons 5420, They aren't "matched pair"...
Could be one is a single channel CPU.
damn...Quote:

how do you see if a E5420 is single channel or dual channel ?
with cpu-Z ?
But isn't the cpu test supposed to happen AFTER the mainboard has tested the ram ? (and ram testing doesn't happen)
I found no mention on the internet of single/dual channels for E5420.
Besides, if there was such a difference betwen E5420,
they would wreck havoc in the Corporate/Oem world
if this wasn't explicitly underlined by a different number.
Besides, i check in cpu-Z and both my xeons are the same familly and the same C0 stepping.
--> I guess, that the problem comes from the motherboard and that there is a fault with the routing of the power coming from the 24pins & P4 & P8 which means that it''ll boot with 1 Cpu but not with 2.
arrrhhh :banana::banana::banana::banana:. I ordered a D5400xs from germany and I'll have to sell the Ws Z7s on ebay... it''ll become much more expensive that I had initially anticipated...
If the D5400xs boots with both cpus...I''ll stil have to buy an E-Atx case.
And if it doesn't boot...I''ll be mightily screwed.
On the bright side, a fresh install of win xp pro gives me great results with cubase...with only 3go of 800mhz ddr2 and 4 cores (-> 8 go and 8 cores might be overkill for audio) it does wonders.
I only get 13% cpu utilissation with a tiny latency
when I had 100% cpu utilisation with a 200ms lattency with my old Amd 3800x2 overclocked at 2.4gz with 2 go of DDR at 400mhz
(/me thinks the fresh windows install did wonders too)
Very strange. I am running two E5420's all right, but they are an exactly matched pair. Don't remember now but I think the box was gray saying server computing..
must be pics of both the CPUs and boxes somewhere around this forum.
I do hope my new 5440's will run in the mobo, I'll better check before I buy another one for them.
Might be the voltage is not matched on the CPU's and the Z7S is throwing a hissy over that.
Other than that all I can think of is the PSU might dislike one connector being on like was mentioned earlier in the thread.
Also the CPU's do not dictate how many channels your memory controller (located in the northbridge on the motherboard) can handle.
well, cpu z says both xeon are working at the same voltageQuote:

[/QUOTE]
To JCool, if you managed to boot with 2 cpus, I bet you'll be able to boot with your two new E5440. Don't worry !
Too bad about the WS Z7S, going the way of the D5400xs will cost me at best 300 euros more
and I'll still have to sell the bad WS Z7s to an unsuspecting ebayer... sigh... /me curses Asus
Besides, I did render jobs in the past but I'm not sure if I''l do it the next 3 years (I build a comp every 3 years) so the 8 cores might be overkill for my everyday audio/recording/mixing usage (which is for now limited to win xp pro).
--> would have been considerably cheaper and simpler to build a comp with 4 cores...and DDR 3
/me curses the premium on Fbdimm
note for self...in the future, only go with standard/mainstream parts.
Sorry to hear about all the problems with the Z7S.
Is there no way you can return the board to Asus ? (RMA)
Tell them you tested a pair of E5410's or E5405's (whatever is on the official list) and tell them the same problem is still there (no boot).
I bought the motherboard on ebay...
Beside I'm french and I don't think asus sells WS Z7S in france...
So I guess that I have no warranty, or do I ?
note to self : don't buy motherboard on ebay...
I don't think your issue is with the board.Quote:

First, do not play with electrical connectors when powered except to read with a meter.
If loose, shut down and fix.
It is possible you damaged the board when you were moving that connector.
I would pull the cpu's, see if you damaged a contact pin in the socket.
Clear the cmos
See if you can get another PSU to borrow, at least 550w and a good quality one.
Make sure your memory is in the proper slots and seated well.
Check every connection to make sure it is properly done.
Sometimes the smallest errors produce the biggest problems.
Do each change one at a time and then try the system.
Good Luck
Tried with 2 new 600+ watts psu :Quote:

There is no way you can't seat them well.
They were memtested and run windows flawlessly
idem with the cpus, you can't go wrong there.
I bet that the problem comes either from the second cpu slot (1%) or from the power connectors (99%), but there is no way to fix that. I think that the board was already malfunctionning when the other guy sold it to me on ebay.
As an AtX case ges a little cramped with this board in, It is quite difficult to make sure the 24 pins and 8 pins connectors are rightly set. Yet this would not damage the board...
And even with connectors just a tiny tiny little bit loose, a motherboard should boot. Yet, this one would light on but not boot with 2 cpus (and it would with 1).
After I noticed that by just changing the angle of a psu cable, it would power off, I made extra sure that all connectors were not loose...and I made lots of tests in and outside the case (in case of short circuits) but it didn't change anything...I bet there is a loose solder connection somewhere...
Anyway, as I want a rock solid (stab my heart asus) computer, even if I by pure luck I managed to repair the power connector, it would't really be satisfying : there would still be a risk of it doing it again.
(and what's the point of havin ECC FBDimm that resist cosmic rays if you use a motherboard that can go into limbo anytime someone uses a vaccum cleaner nearby)
ok, you have done all the right things but that elec connector would still bother me.. At this point I would try and RMA the board..Quote:

Well, the Z7S in its new form definitely is reliable as a rock. I have been crunching at FSB 430 for months now, current uptime is something like 1 month 2 days.
You obviously got a mobo with defective 4pin connector, that's the only reason I know it won't boot with 2 CPUs.
I'd try to RMA with Asus, just say the previous owner didn't give you a receipt, but the mobo must be within warranty because it's not even 6 months old.
Or if you know anyone with good electronic/soldering skills, maybe you can let him replace the faulty connector.
And don't buy mobos on ebay... ;)
Damn, figured I had a few hours before you saw this!:rofl:Quote:

They are quick to write that their motherboards have a three year warranty on their boxes but they do have quite a drastic politic concerning warranties...
don't know if you could call it warranty at all...
Well, we shall see...
Let's give Asus a chance to redeem itself.
after letting my head cool a little, buyng a D5400xs isn't a bright idea after all.
The point was to get 8 cores @ 3 ghz performances at a sub 1000 euros price.
i.e. 20% better performances than nehalem now for a 400 euro premium over a mainstream PC
If it doesn't go well... I have 5 alternatives :
1) sell one xeon and use the pc with the 8g of ram and 4 cores and don't move the case too much
2) sell the mobbo, the fbdimm, both xeons and build a pc with MAINSTREAM parts (ddr2/ddr3 and quadcore)
Sell the old WS Z7s and
3) buy a new WS Z7s and hope it will work this time (
4) buy a D5400xs and a E-ATX case and hope it works
5) buy another dual xeon server mother board (expensive too ^^)
Are you near any large PC retailers?
Might be a good idea to contact Eva2000. He runs i4memory.com and might have some Asus contacts if you cant get it done through proper channels.
Also if you've got the time, check the connectors on the board to see if there are any physical cracks in the solder points or if any pins in the connectors of the board are loose (wiggle them very gently with a pen or something).
hi i get my new workstition, Asus z7s with 2 xeon 5420 8g fb ram, may i ask, how to OC ram speed?, thank for replay,i new for OC... never did it before :rofl::ROTF:
