hello, i'd like to ask what will happen, if i plug different 2xx processors in one motherboard tyan thunder k8we. specifically i mean 248 which is singlecore and 275==dualcore. they are operating at the same frequency and both are supported by the mobo so i think it should be working.. the worst i can imagine is slightly unbalanced machine in terms of hypertransport bandwith... or am i wrong? many thanks for your attention.. mojmir
