Hey all, I just built the HTPC in my sig with a Leadtek K7NCR18GM board, Duron 1600 and 2x256 Corsair ValueRam PC3200.

For some reason, If I clock memory anything above 180Mhz, the on-board graphics give me a hissy-fit and lock up. At 180Mhz FSB, in-Synch, all is well. I can run the Chip at 200+ Mhz FSB with the memory at 183Mhz, but again that's as high as it will go.

Memory is running at 2.7v (max allowable by board) and 10-3-3-2 @ 180, and I tried to relax further to 10-4-4-2.5 when going above...Shouldn't the memory go to 200Mhz because it is PC3200 or is it the Graphics core holding it back.

Also keep in mind that I have a Zalman HS on the northbridge with the stock northbridge fan...stock HS now on southbridge. I can clock the core up to 330Mhz from stock 200Mhz using coolbits but it is Memory Bandwidth limited (reason I want 200Mhz FSB).

what is the chipset rated for? can the memory controller run to 200? if it can then use 1 stick with loosest timings. if that fails try to disable the onboard video and test with another video card if available..
