I just though I would briefly post that my memory issues/timings seem to be pretty much sorted. Thanks to C-N for his response His input along with an earlier posting (#29 way back on page 2 of this thread) by Eva2000 helped me refine and stabilize my memory settings a bit.

Another thums up goes to Praz for clarifying GTL settings and in particular the info on adjusting NB GTL when random cores fail. it turns out my NB GTL and NB voltages were too high.

The following information was for 467 MHz x 7 multiplier. I am currently testing at 475 FSB x 7 multiplier, and am Prime 95 stable at 2hrs 15 minutes so far. Memory timings and voltages remain the same as before.

Memory is set at 5-5-5-12 with 2.16 vDIMM, and tRFC has been set at 30. Previously, settings were 5-5-5-18 with 2.37 vDIMM and tRFC was at 66.

With these settings, Everest Ultimate shows a Memory Read Speed of 9834 MB/s, a Memory Write Speed of 8401 MB/s, a Memory Copy Speed of 8701 MB/s, and a Memory Latency of 51.5 ns.

As per my request for info from all of you, here is my Prime 95 4 hr stable settings as of last night.



I am using the 11/07 BIOS, with 1.4 vCore, 1,55 NB Core, 1.6 FSB VTT, and CPU GTL 1/3=118, CPU GTL 0/2=116, andNB GTL=116.

For the record, I just wanted to note that this is a Q6600 B3 stepping CPU, with batch #L644G191. I believe that once I get water cooled, I will be able to run 8 x with 450-475 FSB (3600-3800 MHz). It is the exta heat of the B3 that is keeping performance down a bit. When I Prime 95 at my current settings, Core temp 0.96 is reading as high as 71 C (although it is typically 64-66 C)
