It's been a while since I've put together a new rig, and I just put together a budget system with the following gear:

E4300
eVGA 650i Ultra
Corsair Twin2x2048 DDR2-800 2GB RAM

I've been tinkering around with the OC settings, however just can't seem to get the crazy settings as posted here on AnandTech (3.420GHz) and Tom's (3.150GHz). Without too much tweaking, I got it up to 2.812GHz (312.5x9) without breaking a sweat.

I would greatly appreciate anyone sharing their OC settings. Thanks.

hey man i just got my c2d ... overclocking them is just as easy as older systems ... look at this guide to see what you should initialy turn off http://forums.anandtech.com/me...=2057083&enterthread=y

and other than that just relax the ram timings at first and find the max FSB multi combo your setup can run... i know that board can do 400+++ so it will be the cpu that limits

also use cpuz to check the actual volt cause if bios says 1.40 i really get about 1.34 in windows

so bump up the volts, turn off the cpu cooling stuff (till you find your OC cause my OC at 3ghz throttles down to 2.2 at 1.02 volt :)

hey also this mobo can run memory linked or unlinked ... i have mine linked with a FSB of 1500 (Actual 1500/QB4 = 375). Which is 375 * 2 = 750mhz but you can keep it unlinked i believe lemme know what works best for you?

Make sure the NB and SB get extra cooling above 300MHz FSB. These chips run HOT and will die or cause problem if not properly cooled. The 650i is a good overclocker, but EVGA when with the cheap design to save $. Also note that there is no fan control unless you use a 4-pin fan.

I can't seem to find the temps of the NB or SB. IS there a way to do it? Speed gives me a system and Aux both at -65C never changing load idle so i dont think that is anything

Not sure if you can get an output from this board. Easy test is to stress test your rig for 1/2 hour. Now touch the NB and SB with your bare hand. If you cannot comfortably hold for at least 15 seconds, then you need to seek better cooling.

Yeah im pretty sure that its very hot to the touch even after booting to windows. But i just put a fan on the side of case blowing down onto the FSB heatsink.

Thanks for everyone's input.

I've got it up to 9x315 (1260) = 2.835GHz, Linked FSB with MEM, CPU Voltage at 1.45 V, 1.40 V, MEM 2.1 V, SPP 1.40 V, 4-4-4-12 1T, and can't seem to get anything higher that is stable. I'm not complaining too much, but in reading what everyone is getting, I thought I'd be able to break 3 GHz without any problems. Surely can't come close to the Anandtech article on this CPU/MB combo at 3.420GHz. Maybe I'll email the author.

I OC'd my eVGA 8800GTS 640MB to 650/1000 which is pretty stable and got 10701 with 3DMarks06. Not too bad.

I'd still like to break 3GHz as everyone is posting around the net. I'm convinced it can be done, but I'd like to know all of the settings.

Thanks again.

Change the RAM Command Rate to 2T - I am actually surprised you've gone that high with 1T.

And get an Infrared Thermometer at Harbor Freight Tools - I paid ~$6 for mine. My NB runs at ~45C, SB was ~62C w/o heatsink, 52C with the HS.

I put the CompUSA heatsink on the SB attached/stuck with the included 3M thermal tape. It's called the "Chipset cooler". I used the little fan for my NB.

Use CPUz to check the stepping of your 4300. If L2, then there's a good chance that the heat is holding back your overclock. This board requires about 0.02-0.03 move volt to achieve the same stabililty as my Abit P35-E.

I also agree with the previous post that you may be pushing your RAM. Run at 1:1 memory divider at rated voltage and timing will keep your RAM speed well below specs. Use Memtest to make sure that your RAM is okay.

Just wanted to follow up with those following this thread...

With the help of Gary Key, the original author of the eVGA 650i review, he suggested the following settings:

9 x 333 (1333) = 3GHz
Sync
4-4-4-9-1T
1.4312 V CPU
1.4 V FSB
2.1 V Memory
1.4 V SPP

And this is very stable. With my 8800 GTS OC'd to 650/1000, I got 10901 3dMarks06. Running a cool 37 C on the CPU, up to 71 C on the GPU.

I'd love to push it further, but for now, this is a very stable setting for a 1.8GHz rated chip.
Was playing BF2 demo at 1600x1200 8xAA high settings very smoothly.
