eVGA 680i SLI + Intel E6300 = 3.44Ghz of speed

Discussion about Intel CPU Motherboards

eVGA 680i SLI + Intel E6300 = 3.44Ghz of speed

Postby Apoptosis » Thu Mar 08, 2007 5:20 pm

I was just playing around with the eVGA 680i SLI and the Intel Core 2 Duo E6300 and got a pretty decent overclock on the E6300 that I thought I'd share...

I was able to hit 489.4MHz FSB with 100% stability... Was able to run double super pi and all that good stuff.

The complete max was 491.9MHz, which isn't too shabby. This is close to the 500MHz FSB mark, which is crazy fast.

Just thought I'd share and these are CPU-Z verified here.

performance questions

Postby road » Fri Mar 09, 2007 12:36 pm

Nearly 500MHz bus is awesome! Over a stock of 266MHz x 7?!
Nice job Apoptosis!!!


I'm rusty on overclocking procedures and getting the most from an overclocked processor. What memory did you put in there?

Is this correct?
500Mhz x 4 (modern intel cpus are quad pumped) = 2000 rated FSB

then slap in:
PC2-8000/DDR2-1000 in dual channel mode?
500Mhz x 2 (ram is double pumped) x 2 (dual channel on mobo) = 2000 FSB

It's not required that cpu and memory bandwidth or FSB match right? Just necessary to get the best performance. What are the correct speeds for PCI (33?) and AGP (66?), and did your board provide acceptable ratios to get it close to the correct speeds? What were the hurdles you ran into, heat?

I've forgotten so much :|

Great results!
espically with all the trouble i hear about the 680 chipset

Hwbot it!!! Nice job nate, not many e6300 can do above 3. That rivals my E6400, but I do it with 1:1 divider

already did it's on HWBOT :) It's the 35th fastest Intel E6300, so it's not enough for points.

Hehe... it's enough for points in my book! :lol: Not that my book matters!

There, fixed that for ya. ;)

Corsair DOMINATOR PC2-8888C4 with AIRFLOW FAN.

That would be correct

You're on the right track, but this board has PCIe for graphics, so it runs at 100MHz.


road wrote:What were the hurdles you ran into, heat?


Heat wasn't an issue as it was water cooled, but voltage is an issue... these 680i boards have a lot of noise in the PCB (which is why they have a new PCB revision now) and limits overclocking. The BIOS also has some holes in it that won't work if you set it to that setting. No one noticed, but my testing was done on BIOS P26, which isn't public yet and fixes many small issues on the 680i SLI. That's why the CPU-Z shot shows the motherboard tab as it shows the new BIOS and the motherboard it was done on ;)

35th fastest?

Postby road » Fri Mar 09, 2007 6:19 pm

Thanks for the reply man. I still can't believe it's 35th rank. What the hell are people doing on the 34 faster systems? It gets better?!
*runs off to check*
Talk about extreme performance/cost. e6300 has less cache right? But similar speed processors seem to be twice the price or more.

You gained about 54% raw cpu speed, sick.

That's pretty impressive Nate, great results.

Most of the guys I know with E6300 are all cranking out over 3G's, a good friend of mine on another forum is getting 3.5 on air with a Gigabyte board......... :shock:

no I stand by what I said, if you look at the databases of Conroes at H and whatnot, 3 is the average oc.

I guess all the folks I know got the pick of the CPU's/MoBo's and are having better luck than the folks that post on benchmark teams or bragging boards.......... 8) .

I think , for the most part it's the NB thats the limiting factor, not the CPU. If you can't get the NB to 450~500 you won't get the CPU much past 3.01Ghz.

Or possibly the ram if running past it's rated speed or not 1:1.
