Precision T3500 Processor Upgrade

The W3680 will work. I have the W3690 in mine with no problems. See this thread:

en.community.dell.com/.../19406351

Just wanted to add, I have a T3500 and just went from a W3503 to an X5650 on the A17 BIOS and it works.  I couldn't be happier.

Sorry for dump up the old thread.

I have read inside out all the related article of T3500 cpu upgrade concerning x5650. Yet I am standing (sitting actually) here without any solid answer or solution. I dug out that all the t3500 mobos with A17 bios upgrade should have handle x5650. I bought such a core, before the change upgraded the BIOS (which was A11) yet the workstation won't even reach BIOS after the change. The x5650 is working in another Dell (T3500 and T5500). The old cpu (w3565) works like charm.

What I did:

-made the mobo "naked" -only vga+ram-> no bios, no boot

-tried another psu -> no bios, no boot

My mobo's ID 9KPNV. IS this whole thing means I should purchase another mobo with ID XPDFK?

I believe it needs to be the newer XPDFK version of the motherboard for 36xx or 56xx series processors.  I don't believe those processors were not available at the time the 09KPNV motherboard was released and can only handle 35xx and 55xx series processors.

Thank You for the response!

I already found on the e-bay XPDFK mobo. My only concern is that I am from Hungary and the mobo is in the USA. And Yes it is used - in Germany the new one costs approx 260$, which is almost the price of my whole configuration :)

I know this is an older discussion.

Wanted to say that I am using a Xeon X5687 processor in 09kpnv (rev a00) to type this message. So I know that 56xx CPU are compatible. I believe newest BIOS (A17) is required.

It is strange indeed. I also installed the  A17 bios still the x5650 stoning the system.

bitpork, what are the POST diagnostic lights doing on the front (the 1 2 3 4 )?  They could be an indicator of the problem before the BIOS screen even comes up. One possibility is that copy of the Mobo has an issue with the local DC-DC voltage converters for the Processor's I/O or Core Voltages (current capability) that are derived from the power supply's voltages.  If you see any bulged electrolytic capacitors around the processor, that could be the issue.  An increase in current demand on a failing DC-DC circuit may prevent the processor from even coming up.  There is a site dedicated to "badcaps".  The Dell Optiplex GX270 is notorious for failing for having bad caps around the processor.  I haven't run across a Precision series with bad caps though. Hope that helps.

Hmm. It was weeks ago. But  tomorrow before the big flat cleaning I can check.

But I am sure the capacitors are not visible wrong. No leaking and no deformity. It still could be ageing however I have no knowledge to measure all of it one by one.

One word like one hundred, after the cpu replacement and push of power button the workstations fans are starting, but that's it.

Coming back after approx 12-14 hours with exact symptoms.

I just picked up at T3500 with XPDFK motherboard and X5550 CPU OEM with 24 GB ram and hoping i can get the X5650 in her

Super. Make sure to Upgrade your BIOS to A17 before putting in X5650 in this board, otherwise it will simply refuse to boot, not even DELL Logo.

So, if I was to purchase a Xeon x5690 for my Dell T3500 with motherboard 09KPNV and BIOS A17, I should be ok? Or not? I am quite curious...

This thread seems to suggest I will be ok, but I don't believe it...

I don't have to go 6-core right now, but I sure would like to!

I have a Xeon W3690 in mine w/ 6 cores and its run perfect for a couple years now. I have the ram maxed out at 24 gigs (if I remember right-I am on my macbook at work right now) and a radeon r9 390 with an upgraded power supply. It runs great and although I don't game much, I can run DOOM at 75-90fps at 1080p.

There are at least 3 versions of the board and within familys there are more than one Revision.
