Precision T3500 Processor Upgrade

We have 4 T3500's all with the W3503 Intel Xeon 2.4GHz Dual Core Processor. They all have the copper heatsinks. After a lot of research I found that they can be upgraded to any of the W35XX processors (just a question of what we want to pay). When I checked out the W3520, I found out that it was identical to the i7 920 processor.

Has anyone upgraded a T3500 with an i7 processor?

Re: Precision T3500 Processor Upgrade

Dell doesn't make Xeon processors.  That does not mean that ANY Xeon ANY series ANY vendor works.

If more than 1 is used they must match exactly stepping and revision aka "S" Spec.

Some vendors with cheap price cheat remarking processors. (I'm not going to get into how this is done) When you put it in your Dell and it frys or otherwise doesn't work they say you did something to it and refuse to refund your money.

It is a good idea to upgrade bios to the latest BEFORE trying to change to a different cpu.

RE: Precision T3500 Processor Upgrade

Yes I would very much like to know the answer to that question as well. Maybe it will be able to run all X56xx and W36xx CPU:s.

Also, I would love to know the maximum amount of RAM. There is a lot of conflicting data on this over the google searches I´ve run.

The technical manual says is only supports 24GB (if it´s ECC ram, not buffered) and only 12GB if its normal DDR3 10600 1333mhz standard ram. All dimms must be dual rank if you want to be able to run these configs, says the manual.

Then there are other sources saying that it can work using 6 x 8GB normal dimms, non buffered, non ECC - as long as it is Double/dual rank dimms in all dimm-slots.

What´s the correct answer? To know what you get on ebay, you really need to get all the data from the dimms to be able to tell these things. And If I contact Corsair about XMS-ram - they can not even answer me it their ram is dual, single or quad rank! Very confusing for someone who is not a wizard in ram-tech.

RE: Precision T3500 Processor Upgrade

What kind of ram and how much in what configuration is well documented. If you want ram and want it to work use crucial's ram configurator and you are fine.

Any ole joes crab shack ram isnt compatible.  If you get it from cruical or from dell its guaranteed to be compatible.  The speed you need depends on which cpu you have and its FSB.  Ranks count also you cannot mix single rank and 2 rank and 4 rank ram.  Its not required but being all from the same vendor for the sets of 3 helps. There are also xeon processors that the 3500 motherboard supports that do not support ECC ram.

 

YOU CANNOT USE 8 GIG Dimms ever.

Recommended Upgrade

It is important to ensure that DIMMs with appropriate number of ranks are populated in each channel for optimal performance. Whenever possible, it is recommended to use dual-rank DIMMs in the system. Dual-rank DIMMs offer better interleaving and hence better performance than single-rank DIMMs.

For instance, a system populated with six 2GB dual-rank DIMMs outperforms a system populated with six 2GB single-rank DIMMs by 7% for SPECjbb2005. Dual-rank DIMMs are also better than quad-rank DIMMs because quad-rank DIMMs will cause the memory speed to be down-clocked.

Another important guideline is to populate equivalent ranks per channel. For instance, mixing one single-rank DIMM and one dual-rank DIMM in a channel is not recommended.

No, not necessarily.  5600 is newer than 5500 and probably wasn't available at the time the motherboard was designed.  Whether it is capable is based on motherboard version and the BIOS.  XPDFK is the part number of a Version 2 motherboard (sticker on the motherboard) for the T3500 and will be listed in the service tag's configuration as a HDPCM part number.  From what I've been able to find is that only this latest version motherboard supports the 3600 & 5600 processors.

The W3520 is not "identical" to the i7 920. In my testing I have found video rendering to happen at nearly half speed on the xeon processor with the same gpu vs the the 920 (beside the fact that D series 920's are known to overclock like mad with little effort... . I however, can confirm this motherboard will adapt well to any of the i7 900 series processors  (like the 950 in mine) as long as you accompany it with non server DDR3 ram I don't think the i7 will play will with parity ram, although it MAY work. I am running corsair XMS3 3x2GB modules 9-9-9-24 with a measured throughput speed of 17GB p/s. Ofcourse, to deal with the difference in TDP I have adapted the 1366 retaining back plate and installed a megahelms 12 heat pipe cooler on the 950, it hardly gets above 120F. Your Xeon copper coolers in those workstations came in two varieties I've seen, four heatpipes across a 4 inch block of fins(would really not be sufficient for an I series) and there was a taller more rare 6 inch tall version... but you can pick up ultra cheap discounted coolers at performancepcs.com.

RE: Precision T3500 Processor Upgrade

I know this thread has been kicking around a while,

But I'm currently attempting an upgrade of a Dell T3500 to an X5650 chip.

upgaded the bios to A17, and installed the new chip, and throws an error:

Amber light, flashing lights 2, 3, 4.

Apparently this is "bios not execute"

If that's the case, it tells me it's either an architecture mismatch, or that the chip is a dud (and it's not new)

Could anyone here shed some light on this issue? is there a trick or jumper somehwere I'm missing?
Or have I purchased a dud chip?

for now I'll just have to live with the old dual core.

Hi,

You did not need to upgrade your bios for this chip. As old as A 08 works.

So with upgraded BIOS, can you boot alright with old processor?

Is, so it is most probably a failed X5650 (Bought from Amazon i guess)

2-3-4 combination is for USB failure an not any system failure.

Do you also get some beeps after some while?

Try Dismantling everything and try putting everything back again.

if no luck, as for a refund.

Booting fine with A17 bios version.

Yes the CPU is a second hand - (from Ebay), contacted seller and he informs me the chip was never tested and offered refund.

RE: Precision T3500 Processor Upgrade

X5000 series is not the same as W3000 series so in general off the bat I would say No its not going to work. There are T3500's on ebay with 6 core W3690 but I have no idea what motherboard version and bios version they have.There was more than 1 motherboard revision.  This is true for many dells.  The E510/5150 for example will not support Pentium D with 2005 motherboard but with A05 bios 2006 revision motherboard works just fine. If you want to try this UPDATE THE BIOS before trying a new cpu.

If the bios is old like A01 then do updates gradually.  Aka A03 A05 A09 A13 etc.

Chris M might have a list of Validated CPU's for this platform.

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?

RE: Precision T3500 Processor Upgrade

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.

RE: Precision T3500 Processor Upgrade

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.

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.

RE: Precision T3500 Processor Upgrade

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!

RE: Precision T3500 Processor Upgrade

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.
