Here are some W3570 at userbecnhmark.com The fastest one is 4GHz.

Well like anyone needed confirmation, TS had very little effect on my E5520 Xeon with the locked down BIOS of the T5500. Hope to get an unlocked W3680 someday! (Grin)

Photo of the Z400 build I did for my gf...still waiting on the pink fans I ordered, and some sleeved extensions, but here's how it sits atm -

- HP Z400 motherboard
- Xeon W3565
- 8GB RAM
- Gigabyte GTX 770 Windforce
- DeepCool Dukase White
- Corsair VS450
- DeepCool Gammaxx 300
- 160 HDD + 320GB HDD

Wow that’s a big case! You think a T5500 motherboard would fit in there?

Possibly...but would more than likely need to drill out the rivets and remove the 5.25" bays...but the T5500 board will fit in most ATX cases if you do that...so yeah. It's a nice case for what I paid for it...was $55 Canadian on sale from $80.

Hmmm...on Newegg, the specs for the white case imply that the 5.25 drive case is now removable.
Wonder if that is a factory mod on the latest versions? They may have switched from rivets to screws?

There is a place about 40 miles from me that is selling one in the box for about the same price ($45 USD). It’s a one off deal....it’s the black one. Even if I have to mod it some, I can drill out the rivets, no problem. If I get some time this coming weekend, may take a drive up and see if they still have it for sale.

I forgot to say when I posted the photo of the Z400 build...the total cost was only $370 Canadian!

I didn't really look all that closely at how the 5.25" bays are attached...perhaps it does use screws...I just assumed rivets. Without taking the case apart...it does look to use screws. My eyes aren't the best, and I was using a flashlight to just peek through the sidepanel...but yeah, I think you are right about the screws vs rivets!

 

[TechyTed]

Well seeing your white version, maybe I should hold out for that? The Dukase looks like a good deal for the price. Its about $56usd right now on sale @ newegg. Thats the shipped price. Not bad.

I like the black version too...I only got the white because my girlfriend wanted a pink and white themed build.

I just bought a $40 875W T5500 PSU with the T5500 harness. I also bought a $10 adapter to use the 2nd 8pin EPS (CPU) cable for a 6+2 GPU cable. It already has 2- 6pin PCIe cables. They can be adapted to an 8 pin PCIe also. So in a single CPU situation, which all of the TS overclocks will be, I can run either 2- 8pin GPUs, or one up to 2x8 pin GPU.
If anyone is wondering why not just adapt the 2-6pin PCIe to 2-8pin PCIe like an aftermarket PSU. The reason is the 12V. power is split into 5 separate 18A. rails, so you need to respect the amount of power budgeted to each existing connector. On a single rail aftermarket PSU you can just use adapters up to the maximum power limit.

Finally got my W3570 in the mail...installed it into my T3500, and was able to get 4GHz (30x multi) with Throttlestop, but wasn't stable, so had to drop back to 3.86GHz (29x multi)...is there anything I can do to get 4GHz stable? I am happy with it anyway, but if there is a setting I missed or something...still going to test on Z400 system as well.

You cannot adjust core voltage on the T3500 so it will be impossible to overclock to the max without more voltage. Maybe years from now some smart guy will find a way to short out the CPU socket and find a way to deliver more voltage so the unlocked CPUs can reach their full potential.

 

[Retrorockit]

The Voltage isn't controlled directly. You're kind of stuck with the auto settings the CPU allows. But TDP ( Total Developed Power in Watts), and TDC (Total Developed Current in Amps) can have their limits raised. Increased cooling might allow more headroom, but the fact is we're all learning how to do this here. I've heard that 4GHz is about all the 45nm CPUs are good for.
Maybe some good old pinmods are needed.

 

[TechyTed]

Sounds pretty good if you are getting 3.8 ghz on a chip using the stock cooler?

I might pick one of those ....like $20 - $25 usd on ebay from China?

...

I have searched but can’t find any CPU pinmod information for the socket 1366 Xeons. At least not like the simple ones used on LGA 775/771 chips. There was some discussion about this years ago, which was all I could find. But maybe there are hidden tricks yet to be discovered.

An old forum thread:

I've never seen any listed, but the VID pinout is in the CPU spec. sheet at Intel. The VID mods never were really easy to copy because different CPUs had differnet starting Voltages to mod from. So there was always an element of start from theory and mod from that. Different versions of LGA 775 also had 2 diiferent VID tables they used and there was a pin that selected that. I wouldn't be surprised if the 45nm and 32nm CPUs differed there also. The unlocked motherboard guys have no need for them. The other Voltmod would be spoofing the feedback pin on the VRM controller chip with a variable pulldown resistor. This requires a Voltmeter readout to be installed because the MB isn't aware of the change.

Actually using a AIO water cooler...CoolIt Eco something rather...just a 120mm radiator. It doesn't run the greatest the way I have my fans setup currently, waiting on some more 120mm fans in the mail to fix that. Temps go up to 80 C at 4GHz, hoping the new fans bring that down a notch.

Water cooling isn't "colder" than air cooling. They both more or less bring the Temperature down to ambient to a greater or lesser degree. The only advantage water has is it can get bigger, and have more fans than air. Also the heat can be dumped remotely. A 120mm AIO isn't any better than a good 120mm air cooler.

I know this...but I picked up the AIO for $10 Canadian...it works well. It's just that it only has a single 120mm fan on it currently, and it's low powered fan, and I am using the rad spot as an exhaust, so it's pushing warm case air through the rad. When my new fans come in will be switching some things around.

 

[Retrorockit]

I use lots of $10-$20 parts to cool my rigs also. My favorite fan is the Delta AFC1512DG 150x50mm 1.8A. 256CFM

Does that fan plug into the T3500 mb like the stock one? I remember you mentioned a larger Dell fan ealier in this thread that you replaced the stock fan.

When I can find some spare time I hope to get the T5500 mb moved into the T3500 case that I bought and move foward on that build.

You weren't at least able to lock the CPU to it's max TB speed?

 

[TechyTed]

Yes, I was able to bump it to the Turboboost speed. But I guess I should have said the multiplier is locked.

Not really news, just confirmation. (Grin)

I've used that fan on the stock fan header in Dimensions, and Optiplexes. But they came with up to 1.6A. fans anyway. The T3500 comes with 2x .8A. fans so some caution is advised.
I would make a splitter and use both fan headers to power the big fan (just 1 CPU PWM wire, but 2 RPM sensor wires) and run the card cage fan from the optional HDD fan header.
Most people here just stick an extra fan on the CPU cooler and call it a day.

I've got a bit of a problem. I just bought a T3500 and a w3570 with the intent to overclock and flip it. Problem is i cant overclock it at all even the slightest bump causes it to crash. Not sure if I've got a bad cpu or something set wrong in the bios. I have a Hp z400 with the same cpu and can run at 4ghz no problem thought about testing this cpu in my rig but really didnt want to tare it down if i dont have to

The Dell should have a 4 LED diagnostic display. Are there any codes displayed there? If so see page 12 here.
