View Full Version : Dual hexcore Z600's

Pretty good price on these. I picked up one yesterday to upgrade my MAME machine. Thinking about getting another to split off some stats tasks but can't quite justify that yet.
I have 2 Z600s. More room inside and the cooling solution is better than the T5500s. I like'em.. especially at that price.

Tempting! The only downside is the memory is 6x4gb, which is only 1gb/thread. And it has only 6 slots, so the DIMMs would have to be replaced to increase the RAM. It looks like it needs PC3-10600 DDR3-1333 ECC, which costs about $100 on ebay for 6x8gb.

Well heck. I thought that was too good of deal. It was just a 2 CPU upgrade kit. Not a full system.
These CPU coolers work great for the CPU on the motherboard, better than the Z600. I need to see if they'll fit on the riser CPU and still keep a fan on riser RAM.

Not very familiar with the two chassis. What are the pros/cons of the Dell T5500 vs HP Z600?
I've got a T5500 and a T7500 - the 7500 has a 2xdual hexcore procs and 48Gb Ram. I like them as they are well put together and really very quiet under full load. I'm certainly hoping the HP one is similar.

I just realized the ebay item I linked to was only a 2 CPU upgrade kit, not a complete system. Thought that price was too good to be true. Sorry.
BTW, I still have some RAM available for these systems. 9x 4GB DIMMS I think.

The Z600/Z800 have both CPUs mounted on the motherboard and each CPU uses the same type of CPU cooler, which is proprietary. Another heatsink may fit but the fan has a special plug and I'm not sure whether it will boot if it's not plugged in.
The T5500 has 1 CPU mounted on the motherboard and comes with a crummy aluminum heatsink. The one I linked to works much better. The 2nd CPU and RAM bank must be mounted on a special riser. The CPU cooling on the riser CPU has something to be desired. They seem to be selling a little cheaper than the Z600s though.

I went digging around on google for images of the guts of both. I have to say, the layout of the Z600 looks less cramped.
Can either of these actually fit the length of a modern GPU? And power connectors?

I think the mobo for each model has two PCIe 2.0 16x speed slots but I'm not sure you you'll never fit two GPUs in them. Not sure what's the max length GPU that will fit. Best I recall, both systems have just one 6 pin PCIe power connector. I have a 750Ti w/6 pin PCIe power in a Z600 and 960 in a T3500 (same basic chassis as T5500) but I power both GPUs with a separate PSU to hopefully make the PSUs last as long as possible.

At one time I had a BIG HD 7950 and a 7790 in a Dell 5500 case. The PSU has plenty of overhead, you just have to use SATA to PCIex power adapters. I don't recommend pairing a big GPU in these cases, but I have a 960 + 750Ti that runs fine even in a non-air conditioned space. My other T5500 has a reference 7970... runs just fine.

Sounds like zombie67 is looking for an itch to scratch. :D
My z600 arrived yesterday. I must say I was a little surprised by the size of the case, it's quite a bit smaller than the T7500 or T5500. I switched on hyperthreading, installed BOINC and let it go. It shut down after about 30mins. Looked in to the BIOS to see if there was any settings on temps but couldn't find anything.
Opened the side of the case and tried again, same thing. Set BOINC to use only 50% of processors, still shuts down. When I came back to it, I had to hit the power switch but it's immediately at a windows lock screen. I just click the lock and it's back in immediately - maybe it's just the power settings in windows, I'll take a look this morning.
Can't say I'm too impressed so far. There is and idle fan setting in the BIOS, should I push that up higher?
Anything else I can do before having to quite and replace the HS/Fans? (Which I hate having to do).

If it's running WIndows, check the Power Options. It may be running Power Saver mode. If so, that's it. Set it to High Performance
If that's not it, run a monitor to show what the core temps are while BOINC is running. See what core temps and power use are. BTW, I do have the case fans set to like 75% in the BIOS and the case cover must be on to get proper air flow.
yeah, I just hooked a monitor up again and it was set for power saving, so I switched that to high performance. I'll see how it runs today. I'll probably switch it to linux at some point anyway.
It's certainly a little bit louder than my T7500 which I can barely hear even under load.

Did it work? Or is there really a HW problem?
Nope, it seems like that was all it was. Just a basic error. Been running at 100% for last 24 hrs.
Still think i prefer the T7500 for the quietness and more room for RAM ( up to 192Gb )!

Thanks. How much bigger than the 5500 is the 7500? Is it significant? Any more room inside for GPUs (length-wise)?
yeah, the T7500 is quite a bit bigger. Take a look here (http://www.ehow.com/info_8653394_difference-between-dell-t5500-t7500.html)
The T5500 is equivalent to the Z600 I think.

Has anyone rolled a T7500 from Win 7 to Win 10?
zombie67
07-09-16, 10:04 PM
I will try that when I get it.
Here is the way it works, per Paul Thurrott on windows weekly : You have a win 7 or win 8/8.1 machine. Once you update (free) to win10, that machine is assigned a win10 license/entitlement forever. Then you use the roll back feature to win7 (or 8/8.1) within 30 days. Then if you ever want to go back to win10, even after the July 30 deadline, you can.
So I am going to go through this process for all my win7 machines prior to july 30, and then roll back.

Well, you can create a media cd after you install windows 10. after that you can install it on that machine or others if you unplug the eithernet upon install.
windows 10 is nice and yes you can disable the automatic updates in services.

Heh. Unplugging the network would make it difficult to run BOINC. ;) But the way I describe leaves you with win7/8/8.1 as long as you like, while also giving the option to upgrade to win10 for free after the deadline. Just keeping the free upgrade option alive, after it expires.

If you do a free "upgrade" from win7/8.1 to win10, you do not receive an activation (product) key, and no amount of digging will uncover one. M$ determines your computer is allowed to use Win10 by memorizing it's hardware configuration and storing this information on their servers, then creating some sort of secret key code from that. If you change your hardware, you're done. If only you had a product key...but wait! M$ will gladly give you a product key for your "free" "upgrade" for the low price of $100 :)

All this is true. But worst case, you still have the win7/8 that you are using now. My point is that there is only up-side with what I described above.

Yep. Heavy as a hippo! But I like it. Very quiet! Plenty of room for a 7970. Two six pin connectors, but only one 8 pin. So a 2nd gpu would be a problem. But no plans for two. 👍

If you are talking about a t7500, watch out for the 8 pin, might be for a second cpu riser card. NOT GPU power!!

That is what I thought at first too. But think not for three reasons:
1) What would it be used for? There is no second CPU power connector on the mobo. Seems odd that Dell would have a custom PSU with a CPU connector that is unusable. This is Dell, after all.
2) I believe the plastic connector molding keying is slightly different, so that you cannot connect an 8-pin CPU to an 8-pin PCIe. I don't have any laying around to verify.
3) The GPU is running fine now. Surely it would have shorted out, assuming it would run at all, if it was a CPU connector.
Anyway, I am not going to sweat it so long as it keeps working. :)
You are correct zombie67, the keying on the CPU 8-pin is indeed different than that of a PCIe 8-pin, so you can't plug one in to the other by mistake.

The next gen of referbs are offered by the same company. T5600 and T7600. Just about the same price, but with better (Sandy Bridge) 8 core CPUs. I just bought this:

And on the HP side of the game you're looking at the following models for the next gen of refurbs:
z220 (z230s aren't that much more) =t1600
z420 (heh 420) =t3600
z620 =t5600 (dual sockets start here)
z820 =t7600

Does anyone have a T5600 or Z620 that could offer any advice or FYI about them? One thing I noticed is on the Z600, a 2nd CPU only required another heatsink/fan while the T5500 required a riser card. Now the Z620 requires a riser for a 2nd CPU but the T5600 doesn't. Am I seeing that correctly?

Looks to be correct. T5600 dual socket motherboard, z620 has a single socket mobo + riser card with 2nd cpu socket.
