No. You'll just get faster RAM, thats all.

If your RAM is the limiting factor then it might help.

You're running at 4GHz on a Q9550 which should be 471x8.5. Even w/ a 1:1 ratio your RAM will already be OC'd to 942MHz from it's 800MHz stock.


A lot of DDR2-800 4-4-4-12 RAM will do DDR2-1000 5-5-5-15 at the same voltage, but you'll have to experiment to find the limits of your RAM. Use a lower FSB speed, lower CPU multi, and use a higher DRAM:FSB ratio to test the limits of your RAM.

I've found the 5:6 divider to work the best on P45 (1:1 worked best on P35), but you need some decent RAM to use it. I originally had some good D9 DDR2-800 RAM that OC'd to 1250 5-5-4-10 when I pushed them to 2.3v. 24/7 I ran then at 1132 5-5-5-15 at 2.15v. A stick died a few months back, and I got a LV DDR2-1150 5-5-5-15 1.8v kit. I'm running them at 1132 now as a replacement.

The mobo you have is one of the best at getting the FSB up there for 45nm quads. I've seen 500FSB before, so you do have some potential, and the RAM might be holding you back in that regard. My board won't stay 24/7 stable at much above 475FSB, but I can boot to 495FSB.

If I had your board I would have gotten some DDR2-1200 and shot for 500FSB w/ the 5:6 FSB:RAM ratio.

Well I guess he has dropped the RAM in order to not limit the CPU OC.

In case he Doesn't drop the ram freq, a new RAM will hit the same wall as the old one, just at a higher freq (for the RAM, usually same freq for the CPU).

You can not run FSB and Ram unlinked with P45 chipset, 1:1 is the lowest FSB : DRAM ratio. So running fsb at 500 Mhz will need a Ram kit capable to run at least at 1000 MHz.

Yes, but even at 1:1 (the lowest setting) his RAM is still OC'd considerably (800MHz to 947MHz) at his current settings. Trying to go higher on the FSB will push the RAM even harder beyond spec.

I explained above how to test the current RAM's limits. Only after that will he know if the RAM is holding the FSB back.

I found the 5:6 divider easier to stabilize than 1:1. So, in the specific case of P45, there might be some potential left to be realized w/ RAM that can hit 1200 stable.

Is it worth the expense and time/energy required to find new stable settings? That's up the the OP. Those last few hundred MHz are always the hardest to stabilize. I spent a few days finding a 4GHz setting on my rig, but then spent another 3-1/2 weeks trying to get to 500FSB. I didn't get there, but I was able to optimize my 4GHz setting a bit in the process.
