Newb OCer needs help getting E6750 up to 460GTX

post #1 of 9
Thread Starter 
I am completely new to OCing, been reading up on it on and off for years and when my MSI 460GTX 1GB arrives in the mail today I was really hoping to lessen the bottleneck as much as possible.

I have Arctic Cooling Freezer 7 Pro aftermarket cooling and fairly good G.SKILL 4GB (2 x 2GB) DDR2 1066 (PC2 8500) RAM so I figured I could, with minimal risk, overclock my Core 2 Duo E6750 2.66GHz. Also, mobo is ASUS P5N-E SLI LGA 775 NVIDIA nForce 650i SLI ATX.

I screenshot'd my BIOS here -> http://edge.imgur.com/GjXAN.jpg

So I know I'm not utilizing my RAM enough and my house stays fairly cool, I'd like as little a bottleneck as possible without risking catching anything on fire until I can afford to upgrade my MoBo/CPU/RAM to keep up with my GFX card.

Any advice on specifically what changes I'd need to make to BIOS settings regarding my processor would be greatly appreciated. And what coordinating changes I should/could change to RAM settings as well (based on my linked hardware) are appreciated as well.

Basically... I'm sort of lost when it comes to FSB and voltages and multipliers.

(Only reason I finally upgraded the gfx card was my old MSI 8800GTS 512mb was listed as min sys. req. for the witcher 2 and **** that)

First off, understanding what everything does,
Your FSB is what is used to increase the cpu frequency as well as increase the ram frequency, increasing the FSB will increase the processor frequency by the multiplier, it can be calculated by FSBxMultiplier=Cpu frequency for eg a E8400 has a multiplier of 8.5, it runs on the default FSB of 333 so 8.5x333=2.8ghz. Knowing this we can find any FSB needed to reach a desiered speed, for your processor a 3.6ghz overclock would be found by 3600/8=450 so a FSB of 450 would be needed

Cpu Vcore (or cpu voltage) is the suplied voltage to your processor, generally the faster the processor is asked to run the more voltage is needed to keep a stable system

So for basic overclocking all you need to do is set the FSB and voltage acordingly. An easy aim for you would be 3.6ghz, to do this simply increase your fsb to 450 giving a cpu frequency of 3.6ghz and increase the cpu vcore to 1.4v. Save the changes and reboot into windows, grab a copy on prime95 and hardware monitor off the internet and run prime95 and hardware monitor at he same time to check stability, you want your core temps to be under 74*C and pass 4 hours of prime95 at least

If you clean the cooler off, you could probably get at least 3.4-3.6ghz. I am using the same cooler with and cpu in another rig, and I can get around 3.5. 3.4 is pretty easy on that processor. just raise the FSB, test stability, if the computer crashes add more vccore. if adding vccore doesn't help then either lower the RAM divider or increase RAM voltage.
Good luck!

Thanks so much for you help. That makes a lot more sense than most of the other explanations I've come across. I'll give it a shot when I get home from work.

I tried 450x8.0 @ 3.6ghz /w 1.4v with no Boot

Went to 400x8.0 @ 3.2 /w 1.4v and walla! Idles temps @ 30c-32c

May try to get the FSB higher this next time.

Is there voltage limit I should not pass?

Also is there a reason RealTemp has my multiplier changing often? Seems to be changing what my ghz is running?

Starting Prime95

Test #1: Test Stopped/Crashed after seconds saying hardware failure.
Maybe a bug?

Test #2: Testing continues! 3.2ghz 1.4v
Worker #1 Stopped due to hardware failure! Stopping test!


Any tips?

P.S. I have the Abit IP35Pro Should it not have on the go OCing? I know it lists it in the BIOS. How do I access that?

I played a little LOL (League of Legends) max temps 63-65 no crashes, but still can not get it to compete through much prime 95

Well after LOL began ERROR crashing I reclocked my CPU back to stock until I get a little more information.

Seems to be back to working.
