C2d Fsb

post #1 of 6
Thread Starter 
Hi, I recently put together a C2D system with an e4300 and gigabyte S3 motherboard with the intention of overclocking. This is with a good watercooling setup.

The question I have is, has anyone had a FSB limited chip?
My particular chip will go to 3.2 (9x355) at 1.45v (higher voltage does nothing). That is perfectly stable.

I tried 400x8 to get the ram running at speed and it was a no go. So I tried 400x7 then 400x6. I could not get it to post at all.

I then thought maybe the motherboard was not capable of that. So I ordered a p5b-e and have the same problem. except this board will only get the chip to 350x9 stable.

So, I find it hard to believe I recieved two crappy clocking boards when most people are getting to ~500 FSB on both of these boards. Now, I was going to purchase a 6600 and hope for better, but if its some other problem im missing I would like to know before I waste my money on another chip.

Also, does anyone think doing to FSB mod to have the chip think its native 266fsb would change anything. I know it makes no sense to do anything, but I have seen stranger things in my overclock days.

Thanks

Lots of the newer C2Ds aren't as good as the old ones. I know it takes extreme voltage to get mine to 400mhz FSB, and it's a 6600. the 4300 should be able to get pretty high FSB though. You may have gotten a bad chip. Not all of them are the same.

I will agree to this! e6420 @ 3.4ghz on a measly 1.36 vcore

Well, I tried the FSB mod in the p5b-e and it said new chip detected, but it didnt change any of the default settings.

As far as the crappy OC. It seems its the memory.

The memory will run fine at 200FSB and DDR-800 setting but at 350FSB+ and DDR 700 or whatever it wont run..... go figure.



I didnt even think it could be it since it was underclocked. But anyways I lowered the timings as much as the motherboard would allow and it posts at 400fsb (DDR800). Memory errors up the arse though.

Try a FSB of 401.

Moving into the next strap should make it easier.
