Capt Proton Posted November 12, 2006 Posted November 12, 2006 This problem also applies to my OCZ PC4000 Plat XTC 2 Gbs as well. Rig is stable (Prime 95, 3D Mark 03, OCCT etc) with CPU at 300 X 10 and memory at 250MHz with the 166 Divider. If I raise the HTT to 310, it freezes just before the Check Sum (Edit:Verifying DMI not Check Sum) message during the boot process and POSTS again. Now, if I put HTT to 260MHz, and set the memory to 200 (1:1), it boots with no problem. I won't say its stable, as I have not tried to do a complete set of tests with this config. My OCZ definitely was not stable. If I set the HTT to 310MHz and my divider to 180, it will boot up no problem with my Centon TCCD. I didn't try using the OCZ, as I didn't think it had a prayer of running that fast. The Centon isn't stable yet at 281MHz, but it will boot and run. Any ideas as to why it won't boot using the 166 divider at 310MHz? Here's the settings I'm using that are Stable with my Centon. OCZ settings were different.

Zelig Posted November 16, 2006 Posted November 16, 2006 Try disabling CPC, I've been playing around with some new (to me) ram and cpu, and can't get any of the dividers to work with CPC enabled. Share this post Link to post Share on other sites More sharing options...
