Hi!

I already searched many forums about this topic and i still can't decide which ram to buy that will be stable for my mobo. (asus p5e3 deluxe wifi, http://www.asus.com/Motherboards/Intel_Socket_775/P5E3_...)

Currently i had 3gb kit (3x1gb) Corsair dominator 1600mhz 8-8-8-24 1,65 ver2.1 modules and the system was unstable freezing randomly. Last week i removed 1 stick and i didn't encounter any freezing problems since.
My cpu is q9300 @2,7ghz. Gpu is Sapphire hd7850 2gb.

So ATM I'm running with 2gb ram which is a bit lol so i'd like to upgrade to 8gb which is max for my mobo.
Ideally for me would be 2x4gb kit but manual says i'm limited to 2gb sticks. Anyone tried 4gb sticks with this mobo? Does x38 chipset even support 4gb modules?

If not i'm limited to 4x2gb modules. Now to frequency. I've read that 1600mhz would put too much stress on my chipset and my system would be unstable. Corsair and geil mem configuration doesn't even shows 1600mhz as available frequency for 8gb kit for my mobo only 1333mhz so... i'm wondering if this will put limitation for oc my cpu. I'm aiming at at least 390-400fsb. One option is buying two 4 gb kits (2x2gb) or one 4gb kit and use the two 1gb sticks for total of 6gb memory would this two combos cause stability problems?

Recap
Has anyone tried 4gb modules on x38 chipset or on asus p5e3 deluxe wifi
4x2gb 1333mhz will this combo limit my cpu oc
Two 4gb kits (2x2gb) or one 4gb kit (2x2gb) with 2gb kit (2x1gb) for total of 6gb will these two combos cause problems?

Thanks in advance

Get four of the same and sell your old ram if you're concerned about overclocking or stability. That's a great 775 board; maybe the best asus ever produced. You'll always have issues when trying to use 3 slots or mixing ram. I would go with 1.5v cl9 9-9-9-24 1600 ram, which should default to a slower speed; you don't have to run it at 1600 if the board is unstable. If your budget is limited, try selling your old ram first on craigslist or anandtech.

Thanks 01die

I'm not from UK so after looking at some online stores in our country they only offer two 8gb kits which are
Corsair vengeance 4x2gb kit 1600mhz, 9-9-9-24, 1,5v (CMZ8GX3M4X1600C9)
and Kingston HyperX 4x2gb kit 1600mhz cl 9 (KHX1600C9D3K4/8GX)

I'm leaning towards Corsair but i'm not sure that ram will be stable on my old x38 chipset. Theoretically it should work but practically...

What do you think is Vengeance good choice for my mobo?

Thanks

Yep already did that but according to qvl the 1600mhz memory as two pairs of Dual-channel memory configuration is labeled as N/A. Two pairs of Dual-channel memory configuration is available at 1333 but only 1gb module (ocz, 7-7-7-20) for total of 4gb memory. According to qvl my mobo is a sport car with handbrake on. But as i already said corsair memory finder does find 4x2gb Dominator, 1333mhz, 9-9-9-24 2t, 1.5V as a working memory for my specific mobo. So only difference between dominator and vengeance is that vengeance runs at 1600mhz only problem with vengeance is memory configuration which is quad channel so...
