meh
My main goal is to OC my system to 3.9 or around 4GHz, only i am having trouble and get bsod or other errors like bootmgr missing or some sort,the highest i ever got is 3.53GHz. i had trouble posting this before idk why but everytime i posted it,it posted it blank,i hope this works,and i think its too long but i posted a link to .txt file,it has my full computer information,but heres the basics:

Quote:
PSU:BFG 650 (GS series)
CPU:Quad core Q9550 (45nm)
GPU:Evga gtx 285
MB :Gigabyte EP45-UD3P
RAM:8GB DDR2 800


full cpu-z specs viewed on,no download needed

This should be your first stop.
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1
http://www.tomshardware.com/forum/240001-29-howto-overc...

Next stop should be a guide for your particular motherboard. Google is your friend.

If you have a Gigabyte motherboard, this will help.

For anything higher than about 3.0 GHz, you will need better cooling. Here are two under $50 heatsinks that are pretty popular:
Sunbeam

Xigmatec Dark Knight
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

They both require a somewhat different approach to applying thermal compound.

And they are pretty large, so they might not fit inside your case.

And here's a good budget cooler:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Keep your core voltage under 1.3625 volts and your core temps under 70 C.

Keep in mind that these are guides, not cookbooks. YMMV. Your Mileage May Vary. Because of all the variables, you may not do as well as someone else with a similar system. Or you may do better.

That's why I wrote:
"Next stop should be a guide for your particular motherboard. Google is your friend."

And included:
"If you have a Gigabyte motherboard, this will help.

The P35 and P45 BIOS's are very similar. Between the guides and google, you should not have any real problems.

There's a good chance that you are inadvertently trying to overclock your memory and that is limiting your CPU OC. Go into the BIOS and if the memory clock multiplier to on AUTO, change it to 2.00. The memory clock will change to a value twice as large as the FSB.

We discuss why not to OC the memory here:

thanks jsc, yea its a doublt post, forgot to delete it,well, i do have 1:1,i figured it out lol,also is it possible to find benchmarks in fps for overclock?
for example you get 30fps on stock at 2.83ghz,then you oc to 3.2ghz how much fps would you gain? im talking in situations like gta 4,i havent been able to find those benchmarks

you ram is limiting your overclock. 800 mghz ram will not do - you need 1066.

And while we are talking about memory, let me say, "There ain't no such thing as DDR2-1066 RAM." Got your attention now, yes? :)  DDR2-1066 RAM is simply DDR2-800 RAM that has been tested to run at the higher speed, usually at an increased voltage and more relaxed timings.
