Question on Bad Axe 2 D975XbX2 & C2D E6700 overclock

post #1 of 2
Thread Starter 
I've never overclocked and have a newbie question. Overclocking is new to me, and I wasn't really originally intending to overclock at all, but wanted to try a rather conservative "easy" overclock on a brand new Conroe system just to see .. well, if I could, I guess.

My full system specs are:

Core 2 Duo E6700
BFG GeForce 8800GTX
2GB CORSAIR XMS2
Intel "Bad Axe 2" D975XBX2 (bios flashed to 12/20's 2395 version)
PC Power & Cooling Silencer 750W
LIAN LI PC-V1000BPlus II case
WD Raptor 74GB 10K SATA150
WD CaviarSE16 320GB 7.2K SATA3
SAMSUNG dual layer 18X DVD±R w/LightScribe
Sony dvd drive
Sound Blaster X-Fi XtremeGamer Fatal1ty Professional
Sennheiser EH350 Headphones

I find any reference to voltages very intimidating, but I did see a post suggesting that a very simple overclock might be done at stock voltages at 300mhz for cpu and lowering the memory from 800FSB to 533, so I tried that and golly it worked! Although I did the changes in BIOS/CMOS, I used the Intel Desktop Control Panel to try to verify it was stable by running a stress test it has, and CPU-Z confirmed the memory was at 1:1 like the other post claimed was ideal for stability. My highest cpu temp under load was 56C, and the post I was reading implied that meant there were very good odds I could just as easily change cpu to 333 and memory to 667 to keep a 1:1 ratio and still stay stable.

(All of that sounds like I know what it MEANS, I don't, but it did make it easy to set the numbers as they said)

Back in Windows, the new settings also stayed stable under testing, temperatures were still very good -- but now I had a new problem. The 667 setting I had put memory at, seems to have changed after saving in CMOS, to 416/835 or something according to IDCC & CPU-Z, and CPU-Z reported I was no longer 1:1 but now 4:5. I a very concerned this is a less "ideal" setting so I rebooted, but CMOS insisted the memory 667 setting was still there. The only thing I can think of, is my memory & board have something called EPP (Enhanced Performance Profiles) and I don't undertsand if that means my computer is "adjusting" my settings after I make them, and if so if I should just trust that it knows what it is doing. Or if I need to change something to make it "stick" to a 1:1 setting and 667 for the memory?


Sorry if this rambles or is unclear as I am .. a newb. Please keep any advice/explanations extremely simple.

Do I need to change anything to get an "ideal" 1:1 ratio for stability, and if so how do I manage this?

edit: I also took this screenshot to show the settings in Windows: http://brashendeavors.net/pix/overclock_e6700.jpg

Hey Brash.

In the BIOS there should be a Divider option. Which you can set to 1:1, which in turn will automatically set it so that whatever FSB you are running your CPU at, the RAM will run at the same frequency (ex. You set the divider to 1:1, set the CPU FSB to 350, The motherboard will set the RAM at 350 also)
