Q9450 limited by GA-P35-DS3L?

[qmalik]

I was just thinking...if I have a GA-P35-DS3L...would that motherboard limit a Q9450?

Question #1:

Q9450 on a GA-P35-DS3L w/ Max OCed w/ RAM max OC
Q6600 on a GA-P35-DS3L w/ Max OCed w/ RAM max OC

What would be this outcome? Performance difference?

Question #2:

same thing but both run on default PC6400 (800) RAM

Q6600@3.2 on GA-P35-DS3L w/ no OC RAM
Q9450@3.2 on GA-P35-DS3L w/ no OC RAM


What would be this outcome? Performance difference?


Bottomline Question: On a GA-P35-DS3L which is the better CPU to have? And if you are no OCing RAM with is the better CPU to have? what is the performance % difference?

A good P35 (with 8phase power regulation) board would likely not limit either chip. Since the DS3L is a (3phase power regulation) value board so it might not make it far above 400MHz with a Q6600. Exceptions are possible.

The performance difference with both chips running at 3.2GHz would be some 5-10%(the difference in clock for clock performance) in favour of the Q9450. The Q9450 would be much faster when using SSE4 (some movie encoding applications use it already). The Q6600 at 3.6GHz (9x400MHz) would likely beat the Q9450 by a small margin in most tasks.

I didnt know that Andrius and i have the same mobo O.O

So if I plan on buying a GA-P35-DS3L, 4gb DDR2 800 (PC2 6400) (w/ no to very little OC), and I do not video encode (i just game)...which CPU would you recommend? Q9450 still worth it?

PS: I would try to OC the FSB, just not the ram so much. I want to get to 3.2

qmalik, if you OC the FSB you OC the RAM. That's why I said investigate your mobo choice, go to the overclocking section and type in "Q9450 overclock". Mobo's hit a wall or sometimes the ram does, when that happens you've hit your limit. With a locked multiplier you need good ram and a good mobo.If you can't afford it downscale to the Q6600. Or get a job so you can afford it.

I've built my system just before X38 was released and GA-P35-DS3P was the best board with LPT/COM on the backpanel. The previews showed no X38 had onboard LPT/COM so it made my choice easier. I'd buy a GA-X38-DS4 today (it has headers for LPT/COM just no ports on the backpanel). My cheap P35 board does 400MHz FSB with 1 notch increases for FSB and (G)MCH voltages.

@ qmalik
You can do 400MHz with just about any P35 board. Like I said above my cheap GA-P35-DS3P (has raid and firewire over the DS3L) does 400MHz with minimal voltage increases. If you don't want to overclock your RAM you will just have to run it at a 1:1 ratio (or Gigaybtes 2.0 setting).

I can't seem to get the GA-P35-DS3L & Q9450 above 2.9 GHz. FSB@360 is rock solid, but FSB@365 will lockup the computer. I spent about 8 hours messing with the voltage settings, rebooting it like a hundred times, and I could not get the FSB@400 on that board. If anyone has on that board, please let me know what you did. TIA.

Have you changed your memory multiplier ?
If not you are overclocking your RAM and that causes instability.
