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

[alucasa]

Well, that's not entirely true... FBDimms will run at 90C and above, but they clock themselves down to prevent overheating, resulting in a perfomance decrese. I don't know how the Z7S acts with overheating memory, but I suggest not to test your luck.

My FB-Dimms had been running over 90c for 8 months before I took it down to be replaced by a Q6600. It was a dual woodcrest. Perhaps, they did downclock but WCG ability wasn't effected. The whole rig was in a tight 2U chassis.

The warranty stickers on the RAM weren't there and I only found ashes by RAM slots.

[jcool]

Yeah, WCG isn't really sensitive when it comes to bandwidth... Difference between dual and quadchannel is zero... BUT winrar kicks ass now

Edit: Holy cow, how did we get to 14 pages?

[oerekum]

We're still waiting on you to watercool all of that stuff.

[jcool]

As I said before, I won't.
If I get to do Harper #2 in the same case I will go the WC route... but for now there's nothing to be gained with WC. It's not going to be quieter or faster, just heavier and more expensive

every interesting thread will get over 10 pages in the wcg-section!

Didn't know you were crunching 2fink
Joined XS team already? Kinda like SETI at tualatin.de back in the day, only better because it actually makes sense now.

PSHH!! Heretic heretic!!


That hardware deserves to be watercooled just for the sake of pwncakes.

i am crunchin for xs since d2ol saaya, me and other germans joined as team_germany, later rosetta was the same! i miss those times. with rod "the catkiller" zilla, the dumps of the cows... roastbeef every sunday!

now i am only running sometimes wcg (laptop is singlecore, dual-core main rig is running only sometimes) and dimes

The 45nm Xeon cpu's run pretty cool (80w TDP) , water really isn't necessary.

should i not choose WC for my rig then? The one you suggested jcool?

well anyways i'll be buying some of the parts in the next few days. I'll get back to you then.

[D_A]

WC'ing won't hurt you any. Keeping the CPUs cooler could extend their life span some ... might make the system quieter ... great for g33k value (WC'd dual socket boxen iz teh l337) ... your choice dude.

Hey Guys new to the forum, (I know, I sound like a cracker already)
I have been reading this thread since I bought a Z7S and had some bad luck with it. Using a single 5420 in socket 0 . Board would not post. After pulling out the ramm it would not even give basic 1 long beep, 2 short beep code for no ramm. When powered on you get one long continuous beep. Would not stop until powering down.
I currently have the board RMA'ed, I'm impatiently waiting it's return. I have since read that Raptor 10k RPM drives are incompatible. Anyone using raptors successfully? I plan to test the processing capability of Protools (audio recording software) using this rig. Thanks ahead of time for any input.

[jcool]

You sure you had the CPU in the right socket? What did the post LED say?
Did you plug in all the power connectors? It won't post unless you have 4 + 4 pin (1 CPU) or 8 + 4 pin (2 CPUs).

[alucasa]

Check its manual.
Some supermicro boards require you to use socket 1 instead of 0 to fuction. That may be the case.
Tyan boards are always socket 0 for single cpu though.

I am not sure about Asus, so read the manual.

[Basevoid]

I had the 8 + 4 pin on the board. (too much for 1 cpu?) The code it was throwing was unidentifiable by asus. They said I was using an unapproved cpu, uh but we know the 5420 should be fine. Asus tech support said socket 0 was correct. I tried it in 01 just for s and giggles. Same problem though. With the ram in the code was 04 I think. Guess I won't know crap till I get another and try again. Raptor drives anyone? a good fast alternative?

[jcool]

Seems like you got a faulty one then :/
I'd try out my new Velocirptor on the Z7S for you, but it was DOA. I can tell you when they give me my RMA.

Raptor compatibility on the Z7S is iffy, some have it working, some do not, it depends on the model of the Raptor and the bios of the Z7S. If you check newegg you can see some model #'s - check the ratings - you will see customer replies and asus replies in line.

As far as RMAing the board, been there, done that. Was supposed to get my replacement Monday and now it's Friday, UPS sent it back, I guess it was damaged during shipping (real reassuring).

The codes I got on the first one were 08, then 07, then FF then shutdown. A tap of the case would cause it to do the same again. I don't know what 04 is, but the last code before the shutdown is important. I would have RMA'd that board as well. Either way, I doubt our problems were the same, I just think we got some of the bad batches.

Raptors won't prevent it from posting, you just might not have raid compatibility although 0201 was supposed to fix that, as well as the latest 3 rev. - according to asus at least. I haven't tested it yet still waiting on my new board. We shall see.

[neveroffline]

Ohhh i understand now.
SInce i am buying the mobo from newegg. i heard it didn't come with a RAM cooler, i guess i'll get the mobo first and see if i need a RAM cooler.

No the ASUS RAM cooler is optional and not included, nor does newegg sell it. Just get a cooler that clips on with some fans, that will keep them cool. I forget the model # I bought, but it's a coolermaster or thermaltake I believe.

[milkmandan]

As I said it will go on the northbridge, and yes you need to remove the stock NB heatsink before. That's the one I had to modify to fit the Thermalrights, see post #1.

I am mounting the mobo vertically, i am not going to be running into any problems will I?

2 CPUs. means 2 radiators right?
Gotta get a godly pump don't I?
or should I enclose each WC CPU block in its own closed loop?

Gimme some suggestions...
How would you go about water cooling this rig if you only had to WC the cpus?

Here's my watercooling setup for my Clovertown rig :

1 triple radiator (1 loop for 2 cpu's is ok)
Swiftech MCP655 pump
2 x EK supreme waterblocks.
Swiftech Microres
1/2" tubing

Hehe, talk about overkill there
These CPUs do not produce that much heat, maybe 180W for both CPUs together in extreme situations. That's something a double 120mm rad could handle easily, go with a triple and you're safe. No need for an extremely powerful pump here either, I'd go with an Eheim 12V variant and sacrifice the 1C difference to the laing for the sake of quietness.
So it's way simpler than you thought, one loop is enough, no need for ultra-highflow pump, fittings etc. Doesn't matter here, this is not a benching rig after all. The last problem you'll have is your CPUs temps with that setup.

Hi guys...

I just recently got my Z7S put together and update the bios with the latest .302 bios. I cannot overclock to 3ghz using 400FSB. My CPUs are the L5420 with TWP of 50 watts. The memory are Quamida 800mhz.

Any help would be appreciated. Here is my spec if that help?

OS: Vista 64 Ultimate
Case: Supermicro SC733TQ
MB: ASUS Z7S WS
CPU: L5420 @ 3 GHZ trying too /w Thermaltake 90 Ultima
Video: 2 ATI 4850 Crossfire
Memory: Quamida 8GB 800mhz
Raid: 3ware 9690sa w/ 4 74 Raptor ADFD @ Raid 10;
Spare HD: WD 640 GB, I-Ram 4GB (Readybooste, Temp, IE)
Sound: Auzentech Prelude /w Logitech Z5500
DVD: 1 Lite-on 20x
LCD Bay: Imon w/ controler
PSU: XIGMATEK 750 watts

minhgi,

What's the default vcore of your L5420 ?

My E5420 with 1.192vcore does 3 Ghz stable but nothing more, so it's possible your cpu needs more vcore.

[minhgi]

not for sure..

I will have to go home and find out. usually, I do mild ocing and never have to mess with the vcore. You think I should up the vcore to e5420 level.

[jcool]

You mean you set FSB to 400 but it's unstable? Try running a smaller multiplier like 7x at FSB 400 and check with prime. If you are stable, then you need a Vcore mod. Good luck with finding the right pins to insulate though, I haven't come across an appropriate howto so far...
