Core 2 duo benchmarks seem low? - Page 3

DDR2 667 Gold?

See if they can do 4-4-4-8 @ 2.2v or try 2.3v, it should do the trick at 400mhz, my Corsair XMS2 675s are doing that @ 442mhz.

If you're on a 1:1 ratio, try a 4:5.

3.2ghz 6700 @ 465mhz fsb= 15 sec Pi
Finally got my ddr2 at 1:1...! When my Pi times dropped on my oc I increased vcore a bit and it bumped back up.

Ram timings are at 4-5-4-15-4 w/ 2.35v

2.35v @ 465? You're killing your RAM, I can do that with 500mhz at 4-4-4-12. For a 465mhz I'd say the most you'll need is 2.2v.

Heck! My XMS2 675s are doing 2.2v at 442mhz on a 4-4-4-8.

I wish I could get my OCZ that high. I had it at 400 once but not stable. 2.1v Now I'm at 330 X 8= 2.64 bla bla bla
oh anything over that and its a nogo

naturalite, its most likely your ECS motherboard, they are horrible overclockers compared to the big Asus, DFI and Gigabyte boards.

EDIT: CL3P20 brings up a good point, bump up your CPU and RAM voltages a bit and see if that helps, if your system is less than stable you may notice a significant drop in benchmark performance as your system struggles to stay stable and not crash, similar to thermal throttling when a CPU is overheating it will lower its speed dynamically to save itself from imminent death.

And as far as the Vdimm goes....Nas, I decided on the extra voltage for the RAM after I ran back-to-back- runs on SiSandra. Ram tested at 6781mbs w/2.15v, 6889mbs w/2.25v, 6984mbs w/2.3v and 7028mbs w/2.35v. Going to 2.4v got me no further improvements. OCZ likes tha V's !.....
Besides if they blow-up, I could wear them around my neck like Flava-Flav......they are 'platinum'!

Your vDimm is fine OCZ requires the extra voltage.
FYI: It often requires 2.1 to run at 800mhz...

Correct...I just lowered my fsb. {now running at 400fsb 8x multi} I have to give the RAM 2.05v to run at 800mhz 4-5-4-15-4. Stock timings are 4-5-4-16-5. Overall, I like the speed of this RAM....but it is not very flexible when it comes to lowering the timings. Lowest stable for me is 4-4-4-14-4. That was good for an improvement of 125mbs.......I think they need to be tighter though, I can run the same timings at virtually all speeds the RAM is stable at....wierd

It should be noted that SuperPi is about 50% CPU and 50% RAM.......so if you took two, identical boards with identical CPUs and gave one 512MB of DDR2553 and the other 2GB of DDR2800 the one with the most, and faster RAM would be faster in SuperPi.......although that score still seems a little off.......
