We had this same issue with a DL-360 which we were configuring to be a counterpart to the 7835. Upon reading further I found some fine print on the compatability list:
1Unless otherwise specified in this document, all further references to the MCS-7835 apply to the MCS-7835, which contains a 733-MHz processor, the MCS-7835-1000, which contains a 1-GHz processor, and the customer-provided DL380.
2The same Cisco-approved hardware configuration standards apply for both the MCS-7835-1000 and the customer-provided Compaq DL380.
*************************************************************************************
3All references to the MCS-7825 in this document apply to the MCS-7825-800, which contains a 800-MHz processor, and the customer-provided Compaq DL320. The same Cisco-approved hardware configuration standards apply for both the MCS-7825-800 and the customer-provided Compaq DL320.
*************************************************************************************
4The MCS-7830 and MCS-7820 require memory upgrades to meet the 512-MB RAM minimum specification. The MCS-7830 is optionally upgradable to 1 GB.
However I do see your server listed here: http://www.cisco.com/en/US/products/hw/voiceapp/ps378/prod_brochure09186a0080107d79.html
I would call your account team or TAC to get a final answer. Two documents conflict eachother.
