Get yourself a third 4GB stick to take advantage of the available triple channel ram.
Once I get the thing, I will see what brand it is and try to find a third one. The options were 2x4, 4x4 and 6x4. They wanted $149 for the 6x4 and $49 for the 2x4, so I got that to keep cost down. I am pretty sure I can complete the 3rd channel for less than a hundred bucks.

You shouldn't have to spend more than $30 for another stick. Ebay or Amazon.

You really should get 3x4GB RAM. The whole point of LGA1366 is 3 channel DDR3 memory. It will run 2 channel but you will be leaving a lot on the table.

Sorry didn't see the 2 previous replies that were on the next page.

This is a good example. This presumes that you will be getting 1333mhz with that system, which is likely.
I will just have to wait and see what I get. Should be here sometime in the coming week. The GPU will be here on Tuesday (I did the slow delivery option, since the computer was gonna be a while).

Hmmm, FedEx said it was delivered on Wednesday!! Damn office employees here are stupid!! I went down there and they said all I had was the one box, something I got from Amazon. Apparently, that goofy woman can't read!! Dammit! I could have already had that sucker up and running!?!?!

Oh well, guess I will raise a little hell on Monday!

That’s why I bought the 4x3 RDIMM kit for the T5500 MB. I really only needed 4x2 for what I am doing, but DDR3 is so cheap, why not go triple channel and get the extra boost?

I think I am going to go ahead and order another 4x3 kit. I will need it eventually if I get that CPU riser card.

So out of curiosity, I purchased a single CPU tray for my mac pro.. I also bought a W3690 unlocked cpu.. So we will see if throttle stop can overclock it.

If it's running Windows it should work. If it's Mac OS you might need some Linux scripts.

Anyone know how hard it is to replace the fans in the fan cage, on a T3500? Can I just buy my own fans and insert them in the cage? They look to be 140's, is that correct?

The fans are 120x38mm. The truth is they are industrial grade fans like Dell uses in their servers. The ones I've seen in the T3500 are Foxconn .9A and I think the CFM is printed on the label. Very few aftermarket fans can equal what you already have. They can be just pulled out of the cage by stretching the rubber "rivets". The 5 pin Dell connector is another issue. Most people just add an 80-90mm fan to the back of the CPU cooler. All the parts around the fan-HDD tray, memory shroud, and the sides of the case, form a duct around the CPU coooler. Some people get Speedfan to work and turn the fans up that way. Typical aftermarket fans are .3A. or less and few of them can make 75CFM. I think the Foxconns are 115CFM. If you pull the blue wire out of the connector they will go to 100% PWM. Just Google Delta Fan Video and you will see a lot of Dell fans running there.

Here are the front case fan specs from a Dell refurb seller web site

(inaccurate specs deleted)

I would trust Retro’s measurements because he has actually built a custon T3500. The 12vdc and .9a specs are correct. That’s what mine are anyway.

I have seen both Foxconn and Sunon brand front fans in these systems. I think they are interchangeable?

The funky Dell 5-pin connector is another thing you will have to deal with, if not using stock fans for the two front fan headers.

I would suggest pulling your fan assy. out It lifts straight up after you remove one screw in the back side of the case. Then you can measure what you already have.
I did a big fan/ cooler swap back on page 8 and 9. But powering the 150x50mm 1.8A 256CFM fan is up to you. Precision 490 fan set. MC527 and JD850. But so far everyone has cooled the overclocks with just an extra CPU fan.
If you get into the slide show on page 8 the last photo should be first.

@lexluthermiester I noticed, a "few" pages back, you mentioned you added a fan to the CPU cooler on your T3500?

What fan header did you use for it, and if you molex-ed it, did you get a low rev fan or do you not mind it at 100%?

I am not going to mod the case on this one. I plan to just try to lock the cores at max Turbo, in Linux, when I have more time, on my multi locked x5670. I am interested in adding a fan to the cooler but, there doesn't seem to be any 4 pin headers on my board. I think, haven't actually looked (googled MB pics), that there may be a 5 pin for the HDD cooling. My board has the solid, finned cooler on the (?)South Branch, which eliminates the fan header for the heat-piped South Branch cooler (on some models?).

@Retrorockit and @TechyTed , thanks for the info. I had no idea it used a 5 pin fan header, nor that they were so "special". ;)
I think, if I were to figure out a decent CPU fan, that won't be just 100%, it could slow down the caged fans and quiet them a touch. Next week, when my 3rd stick of RAM arrives, I will take a closer look at the insides of this beast! So far, this thing, stock clocks, for only 2 days ( not fully spooled up) has catapulted me into the TOP20 on our daily Crunchers Pie List!! Not sure if the triple channel will help with Crunching but, getting it at a solid 6c/12t 3.33GHz will help!

Yup, that's what I've done. The fan I installed is kinda quiet to begin with and once the case side is on it can barely be heard.
Using this one;

I have one on the CPU heatsink and two blowing air out the back vents.

Just as a data point, here are the specs of another brand front fan, which was removed from a T3500.

Sunon, 120mm x 120mm x 35mm.

12v @ .62a (7.4w)

Min 127cfm

Dell p/n YK500-A00

Retro, that big front fan you installed is double the stock CFM...and double the amps!

So remind how you powered it. I am assuming you didn’t use the MB header.

You still have one of the coolest T3500 mods I’ve seen, with all the air cooling gadgets installed.

There is an extra fan header for an HDD fan with the Dell 5 pin header. The first 3 pins are the same order as a 3 pin header. It's by the SATA sockets.
There were some old fans back in the day that had a thermal sensor (thermistor) on the fan instead of VRM. They can only be used on the outlet side.
Nidec TA350DC is one of them. I've seen them with various power ratings up to 1.8A. They're 92mmx38mm and were used to cool Pentium 4 and PentiumD CPUs.
if you bridge across the legs of the thermistor they go to 100%. It could probably be "tuned' with a potentiometer or parallel resistor if you need more speed.

Be sure you get the 3 wire and can see the thermistor as shown. I've seen a 4 wire 2.3A version also.

I bought a BeQuiet 80 mm, for the CPU fan.

Comes w/ a Molex connector that I think connects to that black one with connectors to the fan at different voltages. $27.99. If I am correct, it will be awesomely cool! LOL, I am thinking 7v wiil be enought to slow down the cage fans, and make it quieter and cooler w/out RGB!! :roll:

I might have to zip tie it, to the cooler. I plan to use it as a push, same direction as the 2 cage fans. think I will need an additional exhaust fan. We'll see. I prefer a positive box flow. Right now, the PSU is the only "out" fan.

A bit, but I am a fan, of bequiet fans. I also am intrigued by Cougar fans, don't have any yet but plan to try them, at some point. The i3's, 2 of which I took from the dumpster, at work, will need fans soon. I will probably get some Cougars for them.

That's my 2 cents, on it. :)

Nice to have a Mac Pro here.
I had a funny experience with Geekbench. My Dell Dimension E520 QX6800 3.72Ghz was only recognized as a 2.93 GHz CPU on their chart. They had to extend the chart upwards to contain the score but it was on the chart at it's base speed. That was a couple years ago so it fell off the bottom of the chart last time I looked.
