Pentium D 805 Overclocking - RAM Question

davbo · 22 Jun 2006 at 16:10

I recently built a system with intentions of overclocking the 805 - however i believe i have bought ram that isn't up to the job. :confused:

Spec; Pentium D 805
Asus P5LD2-VM
Samsung DDR2-PC4200

When i push the fsb above 149 (no matter what vcore setting) the system wont boot and i get a overclock failed message. I read the Toms Hardware guide article on overclocking the 805 and this page leads me to think the problem lies with the ram :cool:

Any ideas?

There is no setting for the fsb:ram ratio in my AMIBios (Fully updated) It seems to just decide that itself :rolleyes:

Just seen this now i feel certain that the problem is with my ram, clearly from what they've concluded that ram of speed 533mhz cannot attain a peak overclock from this cpu. I'm looking at higher speed ddr2 ram by G.Skill now ;o

Well I am using DDR2-533mhz and have managed to get 3.8ghz so far.
