we would like to share with you that due to the discontinued status of the Intel® Xeon® Processor X5670 (https://ark.intel.com/content/www/us/en/ark/products/47920/intel-xeon-processor-x5670-12m-cache-2-93-ghz-6-40-gt-s-intel-qpi.html); Intel Customer Service no longer support inquiries for it, but perhaps fellow community members have the knowledge to jump in and help.
