    <description>&lt;P&gt;PBA number is printed on a small label on your board. See &lt;A href="http://www.intel.com/support/network/sb/CS-031176.htm#"&gt;http://www.intel.com/support/network/sb/CS-031176.htm#&lt;/A&gt; q3 AA, TA, SA or PBA numbers. The reason I'm asking for PBA#  is that certain CPUs are only supported on certain PBA revisions. For same reason I asked for CPU model. See &lt;A href="http://www.intel.com/support/motherboards/server/sb/CS-023585.htm"&gt;http://www.intel.com/support/motherboards/server/sb/CS-023585.htm&lt;/A&gt; Important information on support of Intel® Xeon® Processor 5300 and &lt;A href="http://www.intel.com/support/motherboards/server/sb/CS-028540.htm"&gt;http://www.intel.com/support/motherboards/server/sb/CS-028540.htm&lt;/A&gt; Intel® Xeon® Processors 5400 and 5200 support. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The POST code LED translates to 0x21h: Initializing a chipset component. It's pretty early state during POST, before memory initialization. It would be very helpful if you can get the brand/model of your DIMMs and check if it's in the &lt;A href="http://www.intel.com/support/motherboards/server/s5000psl/sb/CS-022924.htm"&gt;http://www.intel.com/support/motherboards/server/s5000psl/sb/CS-022924.htm&lt;/A&gt; Tested memory list. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;After checking the components compatibility, try one CPU in socket 1, and one DIMM in slot A1 first. &lt;/P&gt;</description>

      <description>&lt;P&gt;What kind of memory are you using? And which processor are you using? The POST LEDs you provided, are they in the correct order? It should be MSB, Bit 2, Bit 1, LSB. Also check the PBA#  of your board. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The LEDs of memory slots are red only, and they only light when memory error is detected. &lt;/P&gt;</description>

      <description>&lt;P&gt;Hi edwardzh&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;First of all, thanks so much for answer.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The processors I don´t know the model exactly but they are Xeon match pair (they come with the motherboard)&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Well. The model of the memories is:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;DDR2 667 MHZ FB-DIMMM&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;4 modules of 2 GB each other&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;What is the PBA of my board? How can I check it?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If you see, &lt;A href="http://download.intel.com/support/motherboards/server/sb/d36217006_s5000psl_userguide.pdf"&gt;http://download.intel.com/support/motherboards/server/sb/d36217006_s5000psl_userguide.pdf&lt;/A&gt; &lt;A href="http://download.intel.com/support/motherboards/server/sb/d36217006_s5000psl_userguide.pdf"&gt;http://download.intel.com/support/motherboards/server/sb/d36217006_s5000psl_userguide.pdf&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;on page 9, the leds are in the order I told, but in the page 12 change.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I tell you as appear on page 12:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;MSB LED : off&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Bit 2 LED: off&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Bit 1 LED: red&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;LSB LED: green&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The NIC led are green too.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;+5-volt standby LED also appeared on green.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Status Led green too&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I don´t have more leds lighting..&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks so much and i wait your help &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Have a nice day&lt;/P&gt;</description>

      <description>&lt;P&gt;Your board doesn't support Xeon 5400 series processors. E5310 should be OK. Where did you get the BIOS version? The complete BIOS string should start with S5000.86B. Anyway, you may try to update BIOS with one CPU and one DIMM: &lt;A href="https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&amp;amp;ProdId=2305&amp;amp;DwnldID=19672"&gt;https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&amp;amp;ProdId=2305&amp;amp;DwnldID=19672&lt;/A&gt; Download Center&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi edwardzh&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Ok, they don´t compatible.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;B&gt;So, for being compatible with L5420, what PBA#  must appear on the MOBO?&lt;/B&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The Bios.. I wrong the version.. I will check later.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Another question..&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;B&gt;For update the bios.. Have I only put one cpu, or i can try with the two cpus?&lt;/B&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;At the moment I have two cpus and the 4 modules ram at A,B,C,D DIMM Banks and the MOBO recognizes all of them.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;and finally.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I´m looking for a heatsink with fan:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;A href="http://www.ebay.com/itm/GENUINE-INTEL-XEON-SOCKET-LGA771-PROCESSOR-CPU-COPPER-HEATSINK-WITH-FAN-NEW-/261185624580?pt=US_CPU_Fans_Heatsinks&amp;amp;hash=item3ccfe05a04"&gt;http://www.ebay.com/itm/GENUINE-INTEL-XEON-SOCKET-LGA771-PROCESSOR-CPU-COPPER-HEATSINK-WITH-FAN-NEW-/261185624580?pt=US_CPU_Fans_Heatsinks&amp;amp;hash=item3ccfe05a04&lt;/A&gt; &lt;A href="http://www.ebay.com/itm/GENUINE-INTEL-XEON-SOCKET-LGA771-PROCESSOR-CPU-COPPER-HEATSINK-WITH-FAN-NEW-/261185624580?pt=US_CPU_Fans_Heatsinks&amp;amp;hash=item3ccfe05a04"&gt;http://www.ebay.com/itm/GENUINE-INTEL-XEON-SOCKET-LGA771-PROCESSOR-CPU-COPPER-HEATSINK-WITH-FAN-NEW-/261185624580?pt=US_CPU_Fans_Heatsinks&amp;amp;hash=item3ccfe05a04&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;A href="http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&amp;amp;item=321123617452#"&gt;http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&amp;amp;item=321123617452#&lt;/A&gt; ht_500wt_1156 &lt;A href="http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&amp;amp;item=321123617452#"&gt;http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&amp;amp;item=321123617452#&lt;/A&gt; ht_500wt_1156&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Are they compatible with E5310?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks so much&lt;/P&gt;</description>

      <description>&lt;P&gt;See &lt;A href="http://www.intel.com/support/motherboards/server/sb/CS-028540.htm"&gt;http://www.intel.com/support/motherboards/server/sb/CS-028540.htm&lt;/A&gt; Intel® Xeon® Processors 5400 and 5200 support, as those CPUs has different power requirements, althought the socket is the same. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If you can boot the system already, yes you can update the BIOS with all those components installed. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;As for the fan heatsink, both links you provided are same model (D39267-002), and it's goof for Xeon 5xxx series up to 120W. &lt;/P&gt;</description>

      <description>&lt;P&gt;Ok edwardzh.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So.. if the PBA of the s5000psl was:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;E11027-302&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;or&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;E11025-302&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;B&gt;Those will be compatible with my L5420 no?&lt;/B&gt;&lt;/P&gt;&lt;P&gt;&lt;B&gt;&amp;nbsp;&lt;/B&gt;&lt;/P&gt;&lt;P&gt;&lt;B&gt;I see one Mobo on EBAY that has E11027-101, that one isn´t compatible with L5420 no?&amp;nbsp;&lt;/B&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I don´t understand one thing...&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;B&gt;For being matched pair L5420:&lt;/B&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;L5420&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;INTEL XEON&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;SLARP COSTA RICA&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;2.50 GHZ/ 12 MB / 1333&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;381****** and the other one has 382*****&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;B&gt;Apart of being both SLARP/SLBBR, they must have the same batch or it´s not important for being matched pair?&lt;/B&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;It´s a thing that I don´t have clear about it..&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks edwardzh for explain clearly all &lt;/P&gt;</description>

      <description>&lt;P&gt;Yes PBA#  starts with "E" can support L5420. Difference between SLARP and SLBBR is stepping. Normally mixing CPUs with +/- 1 stepping is OK, but remember to install the lower stepping in socket 1. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Check the page below for stepping information of your CPU: &lt;/P&gt;&lt;P&gt;&lt;A href="http://ark.intel.com/products/33929/Intel-Xeon-Processor-L5420-12M-Cache-2_50-GHz-1333-MHz-FSB#"&gt;http://ark.intel.com/products/33929/Intel-Xeon-Processor-L5420-12M-Cache-2_50-GHz-1333-MHz-FSB#&lt;/A&gt; orderingordering ARK | Intel&amp;amp;# 174; Xeon&amp;amp;# 174; Processor L5420 (12M Cache, 2.50 GHz, 1333 MHz FSB)&lt;/P&gt;</description>

      <description>&lt;P&gt;I think I don´t explain as clearly as I waited..&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;My those L5420 cpus are SLARP, but they don´t have the same batch number.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;For being "MATCHED PAIR", what are the features that they must have?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;- Same SLARP + Same batch number&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;or&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;- Same SLARP only.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks for all &lt;/P&gt;</description>

      <description>&lt;P&gt;Batch number doesn't matter. What matters is stepping. Same sSpec#  means same stepping, so processors with same sSpec#  would definitely be OK.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;As I said earlier, +/- one stepping is normally also acceptable. So you can mix SLARP and SLBBR. It's recommended to populate the CPU with lower stepping in slot 1, so SLARP goes to CPU slot 1, and SLBBR goes to slot 2 if you mix them.  &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Hope it's clear enough. &lt;/P&gt;</description>
