De problemen met de memory repeater hub van de i840 chipset blijken niet alleen voor te komen op Intel borden. Ook SuperMicro, toch een respectabele fabrikant van serverplanken, heeft klanten gewaarschuwd dat de werking van haar i840 mobo niet 100% wordt gegarandeerd bij gebruik van ECC SDRAM:
The letter said: "Intel have announced that the current stepping of Intel's 840 chipset has made the MRH's sensitive to noise generated by switching on the MRHS-I/O pins. In accordance with Intel policy, we must as a result, claim that the current Super PIII DME and SUPER PIII DM3 motherboards are not guaranteed to be 100% ECC compatible. Therefore, after 30 days from the purchase date, memory problems related to the chipset:"1. Can not be returned for credit"
"2. Can not be returned for RMA"
"3. Can not be exchanged for future stepping 840 chipset boards"Unless distributors sign up to these terms and conditions, Super Micro is refusing to supply these two models. Super Micro is also asking distributors to contact customers who have already bought these mainboards to alert them of this limited warranty.
