D30 4229-35U processor upgrade options

2015-04-05, 4:01 AM

As I understand Lenovo PSRef for 4229 machines (4/17/13 v.435), they support, among others, 1x Xeon E5-2609 (what mine came with); 2x E5-2609; 2x E5-2620; and 2x E5 2640 processors.  A second 4GB 1333MHz UDIMM and second 500GB 3.5" SATA HD shipped with it and I installed them.  Along with adding another 2x 4GB chips, either adding another E5-2609 or replacing the existing one with 2x 2620s or 2x 2640s seem the way to go to boost performance on my main applications, AutoCAD/Revit 2014 and MS Office.  Since my machine was built, thought better-performing 2600 v2 and v3 processors have come out.  I was told that my c602 chip set limits my options to v2 or earlier. 

 

How much performance the added memory would provide I don't know but from what I can tell, adding 1x 2609 to the 1x existing would nearly double the PassMark for about $300; replacing the 1x 2609 with 2x 2620 would nearly triple the PassMark but cost above $800; with 2x 2620 v2 would fully triple the PassMark but for under $800; and with 2x 2640 v2 would more than triple the PassMark but cost about $2K.  To the extent true, obviously adding a second 2609 would be the better value but the better performance of 2x 2620 v2 might be worth the higher cost.  With all that would be involved in replacing the machine itself, that will not be an option anytime soon.

 

My questions are:

 

Will my machine in fact allow replacement of the 1x 2609 with 2x 2620 or 2x 2620 v2?

 

What are the PNs of any that I can?

 

What is the PN of the fan each processor would require?

 

Whatever you can tell me on any of this I'll really appreciate.

All very accurate :)  AutoCAD doesn't care about cores, but loves frequency.  I7 CPUs will usually perform pretty well with it, but that's not an option in a D30 platform...you have to stick with E5 Xeon.

 

So I fully agree that you would benefit the most by looking at the frequency optimized SKUs.  I'd probably recommend the E5-2643 v1 or the E5-2637 v1 as both of these are low core count frequency optimized SKUs.

 

Your stock heatsinks should work just fine for either of those SKUs.

 

Here are the FRU numbers:

E5-2643 v1 - 03T8380

E5-2637 v1 - 03T8383

E5-2630 v1 - 03T8378

CPU heatsink (135W or less) - 03W5426

 

I don't know off the top of my head if any of these are available as official options, so you'd have to search the site for that.  For the CPUs, as long as you can be certain what you're ordering is M-1 stepping (for the 2643 and 2637....for the 2630 it would be C-2 stepping) you can likely get these from a variety of sources.  Be weary of anything that doesn't have the processor name/description etched on the heatspreader if buying on the open market.

Well, since your system is a 4229 machine type, I think we can start by ruliing out any v2 (and certainly v3) processors.  

 

v2 = Ivy Bridge - supported by the C602 chipset, but ONLY when the correct ME code is present in BIOS

v3 = Haswell - not supported by the C602 chipset

 

Unfortunately, the ME code that shipped with machine type 4229 systems was limited to ME7.  ME8 is required to support Ivy Bridge, but Intel does not support updating the ME code "between generations".  This means that ME7 could be updated to ME7.1 in the field via a BIOS flash, but ME7 cannot be updated to ME8 in the field as that would be a new generation of ME code.  This is why newer D30 systems (launched after Ivy Bridge) have a BIOS with a completely different BIOS ID.    Unfortunately, this really limits the CPU upgrade paths available for base 30-series systems...but our hands are tied by Intel with this.

 

That being said, you can upgrade your D30 to just bout any Sandy Bridge (v1) CPU that you want to install.  Since your original CPU was a 2609 is an 80W CPU, you can install any CPUs up to 135W with your stock heatsinks.  Any CPU selections rated at a higher TDP would require new heatsinks (capable of supporting up to 150W each which is the max TDP supported on the platform).

 

So I would say the next step is to use this info to take a look at and start to narrow down your processor selection.  Once you get a better idea of exactly which CPU you need, we can help you with part numbers/FRUs.

Thanks very much for the detailed explanation of the limited processor upgrades possible.  I'll get back to you when I've had a chance to look into them.

Based on what you reported, I looked at some v1 Sandy Bridge options but
also for what I could find on the attributes important in running AutoCAD.
The main one seemed to be that, according to one source, "AutoCAD is
primarily a single-threaded application, meaning it only utilizes one
physical core at a time. Most AutoCAD features cannot take advantage of
multi-core CPUs." The article went on to say that ". . . when selecting a
CPU, we look to Intel's Core i7-4XXX series and Xeon E5-2XXX series. In
terms of dollar-per-GHz, the i7 line will offer the best performance for
AutoCAD."



However, given that E5-2600 family processors are spec'd for my machine, I'm
inclined to stay with that. Of those, for AutoCAD, anyway, GHz seeming to
be the thing to go for, the one that stands out is the 2643, with a clock
speed of 3.30 GHz, 43% higher than the next lower-in-cost 2.3 GHz 2630.
However, I'm open to something else you might recommend.



As far as the TDP, Intel shows 130W for the 2643, so a stock heatsink, as
you mentioned, should work.



Back to the PNs, I'd now like to get those for the 2643 v1 and 2630 v1,
along with the PN for the heatsink. Whichever processor I end up choosing,
I plan to install two of them to replace the single 2609.



Thanks very much for your help

Thanks so much for all the information.  I now can buy with confidence that what I do will work and be a good choice.  From the source searching I done so far, the challenge now will be to find a seller I can buy from with confidence without having to pay an inflated price.  That I think I can manage.

OK so there is one more option you might want to consider.  Keep in mind this isn't officially supported, but I was able to track down an older D30 and check it out to confirm that it should be possible.

 

If you really want the best bang for your buck, consider using one of the E5-16XX Sandy Bridge (v1) CPUs.  These CPUs usually get to pretty high clocks and can do so at a better price point.  I'd consider the E5-1620/50/60 v1 CPUs. 

 

There are some drawbacks though:

1.  You won't be able to use any of the DIMM slots from CPU2 as there is no QPI link between the sockets when an E5-16XX is installed. 

 

2.  If you ever decide you need the second CPU, you can't tack on another E5-16XX processor...you'd have to dump the E5-16XX in lieu of two E5-26XX.

 

 

Again, this is not officially supported.  However, I think it's really low risk since BIOS appears to have the correct processor patches to allow the E5-16XX CPUs to boot (at least the 1620 I checked worked OK).  This is something we added support for when Ivy Bridge hit....it was just deemed not a high enough priority to go back and qualify the same thing on Sandy Bridge.

 

CPU TDP for those processors are all 130W, so you should be OK with your stock fansink.

 

 

Just another option to consider.

See my previous post.  I just edited my original as I stumbled on a D30 system to check faster than I thought I would.

I've decided to go with the E5-2643s and be done with it as far as processing for the remaining life of this machine.  But I wanted to check also on upgrading memory. 

 

The E5-2609 apparently supports up to 1066 MHz memory, but the E5-2643, up to 1600 MHz. I have 8 GB (2x 4GB ECC UDIMMs) now (the 8GB; 2x 4GB I know; the other I'm inferring from specs) but was thinking of going up to 32 GB (4x 8GB 1600MHz ECC UDIMMs ?) Although I’m not sure it’s required, given what memory is selling for these days, I’m thinking that, if I do go for that much more, I should just replace all of it with the fastest.  Have I got this right?  If not, what should I get in the same range?  And what is the PN/FRU of what I should get? 

 

With the added/upgraded memory, I intend this to be it.  Fini!
