I have an ASUS P5K-SE, I have 1x1Gig PC2-5300 and 1x1Gig PC2-6400 on it. I was looking into adding another 2 gigs of PC2-6400 (which will cost me around $40) when I saw a special on TigerDirect for 2x2Gigs of PC2-9200 for $54 (after rebate) http://www.tigerdirect.com/applica [...] CatId=3413

My question is, since my ASUS board allows up to DDR2 1066, will the new ram just under perform to match the allowed speed dictated by my motherboard? Also will this cause any complications if I try to OC my E8400 to 4Ghz since I've read that when you OC over 3.6Ghz you will need to adjust the timings on your memory??

If you buy this, don't could be work at 1150MHz, only will work to 1066MHz

Do you mean to say the 1150mhz sticks will work at 1055mhz or that the board will not work with 1150hmhz?

Any help would would be appreciated.

The RAM will work, but it will default down to the slower speed, unless you OC the RAM in your BIOS. It shouldn't be a problem.

What are you looking to have in the computer after you buy the new sticks? 6 total gigs? Or just the 4 from two new sticks?

What OS are you running?

By default, the RAM only work to 1066MHz max 'cause is the default of the mobo, if you want that the RAM work to 1150MHz you need OC in the BIOS....

For the price I saw on TigerDirect I figured I might as well just replace the sticks altogether. Unless you think the jump from 800MHz to 1150MHz is not that great?

The manual says the motherboard natively supports DDR2-1066MHz but I can still overclock it to support 1150MHz??

Need to consider these overclocking issues:

Will the memory sticks and bios allow for the overclocking? - the bios will not allow some sticks to overclock and some sticks can not be overclocked without problems.

Check out your motherboard manual and maker of sticks to determine.

Good Luck - Make it Happen!

I think you should replace the current sticks with the full 4 gigs - 2x2. That way you will have dual channel with 4 total gigs. You would only want to keep in the other sticks if you are using a 64-bit system. A 32-bit system (most windows XP, and I think more than half of Vista's) are 32-bit (You would know if you have a 64-bit system) only allow a maximum of 4gb to be employed by the system. This includes any RAM on a video card you may have. Therefore, with the 4 gigs you are currently looking to buy, you would be maxing the system anyway.

So only use the new stuff. After dropping it in, make sure that the system registers all 4 gigs. Also, you can check the BIOS and see what it is registering as the speed.

If this is your board (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131189) it supports up to 8gb, but as stated, the OS will only allow 4gb max.

Let us know if you are using a 64-bit system, or plan to upgrade to Windows 7 - which if you do, you will most likely want to install the 64-bit version.

So I was looking into the MOBO. It appears that it may actually be a 800MHz board, which will allow some sticks to run at 1050 - some people had this problem, and some reviews rated it as a 800 MHz board. I would recommend looking at the MOBO manual before moving forward, to see what it says about the RAM you can put in it.

The manual states: "This chipset officially supports DDR2-800MHz. With the ASUS Super Memspeed TEchnology, this motherboard natively supports up to DDR2-1066MHz."

Apparently if I put 1066MHz sticks on it I just have to adjust the DRAM Frequency in the BIOS. I just want to know if 1150MHz will work and just be set at 1066MHz or not.
And yes I have ordered Win7 Pro 64bit so if thats the case should I bundle all my RAM together? But then they will all under perform at the lowest setting (800MHZ) right?

Yes, if you put the DDR2 1150MHz, you could be set at 1066MHz (in some cases the system set auto to 1066MHz). And yes, all the ram could be set to 800MHz, the lowest setting.
