Q9450

ASUS RAMPAGE FORMULA LGA 775 Intel X48

or

GIGABYTE GA-X48-DQ6 LGA 775 Intel X48

Ram =
CORSAIR DOMINATOR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066
or
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066


I am wanting to know what kind of success I will be able to get or I should expect when trying to OC the q9450 with the above stuff. I have not been sold on anything yet and would like opinions.

I plan to be air cooling with the XIGMATEK HDT-S1284 120mm Rifle CPU Cooler, but open for suggestions on this as well.

Case = COOLER MASTER RC-690-KKN1-GP Black

I'd think 3.6GHz is very doable, and if you feel like taking the risk, 4GHz isn't impossible. Either ram will work, so go for the one with tighter timings. If they are the same, then go for the cheaper one.

Watch out for the motherboard temps, but since that case has plenty of fans, I don't thing it'll be a problem.

I have the gigabyte GA-x48-DQ6 and I'm loving it. The northbridge and southbridge both have massive heatsinks and the underside of the cpu socket also has a sizable heatspreader. Currently I am at 3.2ghz @ stock volts running mid to high 30c temps on the board and after playing with the memory divider I managed to get to 440 FSB without a voltage tweak (was only running 2.8ghz on the cpu) which with that CPU would equal 3.5ghz with probably only a voltage increase on the cpu.

You might be able to do 463x 8 on Q9450 on Gigabyte Board. I have made to 3.7ghz on GA-P35-DS3P fine prime95 stable. Bye

Ok that is a few for the gigabyte board no asus lovers or are there problems with it? Eventually I am going to 8gb ram with vista 64.

But for now just piece'n it together. 1st build since 2003 ish or earlier.

I think either board will be fine. I have the gigabyte, others have the ASUS. I think either one will perform quite well for you. Just be sure to check and see if the ram you are looking at is compatible. Some boards have problems with 1066 ram.

I'm in the same boat as you for the new cards. Its killing me with a 7900gt ko!

OK Im up and running at 3.4 (425X8). 1.2V I will fine tune and find max over the netx few days.

I have a Zalman 9500 for now and my temps at 100% load are 57-58C Max

The AC5 has not set yet so I ca see a 1-2C drop in a few days.

I have:
Gigabyte X48-DS4
Q9450
Xigmatek S-1283 on a Thermalright bolt through kit ( I love it :) )
Corsair XMS2 6400C5 800 (2x2G)

Currently running at 3.4GHz but needed BIOS setting of 1.275V to run Prime95 Small FFTs. CPUZ shows 1.232V.

My temps are: CPU 51; Cores: minimum of 24 degrees to TjMax. I don't know what TjMax for this CPU is, so I don't know the exact core temps. Intel told me not to worry about cores, just the CPU temp.

Memory may be an issue, I'm letting the mobo set it. If I try the standard settings it won't boot.

I'm still testing this out (started OC'ing last night, current test is only 1 hour old) and if it runs stable overnight, I'll revisit the memory issue tomorrow.

Craig.

1haplo ..... I have the same setup and OCZ memory, let me know if you run into any problems along the way. Just placed the order and am looking at building it the first week in July. I'm looking forward to a good build! Kevin
