NIC Tip Did The TRICk

April 9, 2001 admin Uncategorized 0

A NIC Tip Just got a note suggesting that if you are having problems with a NIC
(or actually any other PCI device), you should increase PCI latency from 32 to 64).
Couldn’t hurt to try. Ed

__________________________________________

This worked out excellent for me! My Celeron 800 was stuck at 126FSB (1/4 PCI divider, thus underclocked) and increasing the PCI latency to 64 got me over the edge! I can now run 132FSB, so I took it one step down to 131FSB @ 1.75Vc/3.5Vio and an Alpha PEP66T. I had been running at 133 and up to 140FSB but it takes lowering the in-order-ceue-depth to ‘1’ which dramatically decreases (memory?) performance…

I’m happy at 131 because my PCI is now almost running within spec, and I’ve even created and restored a few system images under DOS, this would lock-up nicely before, now it’s rock solid!
