I need help to overclock a intel Q9550 on EP45-UD3P mobo

[SkyNet2032]

This is my first time overclocking. I would like to overclock my CPU to 3.6Ghz. Ram is at 4-4-4-12 stock and CPU is also at stock at 2.83Ghz GPU is overclocked a little. Any help would be apreciated, Thanks

SPECS:

CPU: q9550 (CPUZ says E0 stepping) 2.83ghz stock
MOB: Gigabyte EP45-UD3P
GPU: VisionTech 4870
RAM: 8gb Corsair XMS2 800 DDR2
COOLING: CPU XigmaTek HDT-S1283

A good starting point is here....

Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

A good 8 pages of reading and you will come across a lot of info and likely someone that has a rig close to your specs that has finally settled on a good OC.

Peruse the forum a bit and read up on other peoples posts for a good starting point. Use the "search" function as well. We are trying to minimize the same question being asked in 100 different posts.

Also look at peoples sigs... a lot of info right there ;)

I will check it out and follow that advice thanks much cdelong!

Is easytune6 a smart overclocking tool to use ?

[Lsdmeasap]

Na, you should only use that for Looking at your temps or voltages. All overclocking should be done in the BIOS.

Please give me a link to your ram, and I will give you some settings to try for 3.6

While you wait, this for sure should be set/changed for stock even. I will edit this or repost with full settings once I get your ram link

Hi lsd nice to hear from you :) Sorry i got back late i was trying some settings in bios but i couldnt boot for a while due to my lack of knowledge in OC :(

Ok i got a link

Ahh, thats all good! Gotta learn sometime

Thanks for the link, here would be optimal settings for you to use at 3.6. CPU Voltage of course will be up to you and your chip to find

CPU Vcore….……….........................: All up to your chip.  Keep in mind what you set here is not what you get in windows (You can check the difference with CPU-z, but it is also not always the same and may vary at different volt ranges)......  I see some do 3.6+ on 1.24 or Less Actual, some need 1.25-1.3 or more.  So set high enough for sure to boot then you can lower later

Yes, you can if you set things right. Set to all the highest I suggested and pick a high Vcore and see if it works, if not try more

I incountered this problem on prime95 what could this be? :(

[SkyNet2032]

Could this be a Vcore problem? i booted into wondows just fine with 1.23 volts at 3.6ghz. maybe it needs more juice to run prime95. It also doesnt seem to be a memory issue do to memtest not giving me any errors at this time with 105% coverage in about 20minutes. I seriously have no idea.. ^__^
