Frustrated with Overclocking with the S3 Motherboard!!!

I've had this motherboard for since last August and if you read my previous threads it took me countless weeks to get my e6400 to overclock properly to respectable levels. (3.4-3.5ghz on Arctic Cooler Freezer 7 Pro).

However, just recently, I got a nice christmas present in the form of the e6600 and was excited at how much I could get on a Week 31 e6600 since I've heard great things about the recent weeks not needing such high increases in voltages to reach certain overclocking results.

With that in mind, I started overclocking e6600 on the S3 motherboard after a week or so of burn-in with a newly bought Scythe Ninja (which lowered my temperatures instantly). But I ran into a problem I would have hoped to have avoided.

As some of you may know, my S3 motherboard strangely has a black hole in terms of FSB in that I cannot POST at all when the FSB set between 340mhz - 425mhz. Therefore, as I slowly moved my FSB from the stock 266mhz to the 340mhz, lo and behold, my system fails to post and reverts back to stock settings.

I tried all the way to 400mhz and just gave up because I knew at +400mhz x 9 I suspected I needed to put more voltage that I was comfortable with.

As a result, this is my dilemma. I am left with a board with FSB holes from 340mhz-425mhz, which would have been ok if I still had my e6400, since I was able to push my 10th Anniversary Crucial Memory to +425mhz x 8 on the e6400. However, on a the e6600, most of the overclocks have an FSB of 350mhz-400mhz for an overclock of around 3.6ghz with 1.4-1.5v on the vcore, which just happens to be the bloody FSB holes my S3 motherboard has.

GAh, someone help me. Is my best option just to sell this motherboard and buy another one such as the DS3 or the Asus P5B deluxe because this is getting frustrating. It can't be the memory and I'm pretty sure it's not the processor (unless I got very unlucky).

Feedback and help would be greatly appreciated.
Thanks..!!

EDIT: Should I take the multiplier down a notch on my e6600 and run it on xxxmhz x 8 instead of setting it at x9 and try to pump up the FSB to 425? Is it the same performance between these two setups? :
Setup 1: 450x8 = 3.6ghz OC on e6600
Setup 2: 400x9 = 3.6ghz OC on the same e6600


I would actually test this out to see whether it made any noticeable performance difference but then again this stupid motherboard has its respective FSB holes. If anyone could give it a shot, it'd be helpful because if there was no difference at all I guess I'd be satisfied with taking the multipler down a notch and take advantage of the incredible overclocking potential of my memory. I was actually able to run this memory for 8 hours on Memtest with no errors on another setup and overclock an e6300 past 3.6ghz terroritory (in an attempt to convince a friend select D9 memory is well worth the price).

Try running the multiplier at x8 and the FSB at 450 if you can get it that high, and see if it works.

By the way, what timings and voltage were you running your Crucial 10th at, at a FSB of 425Mhz?

I was running FSB and MCH voltage +2 for both with the vcore at 1.425 to make sure it wasn't the voltage limiting any overclock.

Will, try running 450 x 8 when I get home in 2 hours. I have a hunch, the system will POST at a lowered multipler.

I have 2 S3's and I dont have those fsb walls...

My E6600 is running on one of mine now at 9x378, but has ran 8x401 and 8x425.....

Franky I haven't ever tried mine at anything lower than 400, and I go from 401 to 460 (highest I've tried so far) with no problems yet.

@ OP: I meant what vDIMM :p.

Hmm, do you have any idea why I just can't seem to post in those regions?
From my last overclocking adventure, my problems stemmed from those holes. Someone brought up memory straps.

EDIT: What revision do you have Duvie? Does that count for something? I believe I have the rev 1.0 but not sure.

I still haven't had the guts to go past 2.1V, last time I did that I changed something else wrong and ended up resetting the CMOS. Oh well, trial and error! ;)

Anyways, does anyone know whether there is a performance decrease if I lower the multipler and up the FSB so that I still manage an overall overclock of 3.6ghz?

If it's still 3.6Ghz the only difference will be that the FSB will be higher, right? Well, running a higher FSB means your memory runs faster which means that provided it can take it (it really should, mine does 920Mhz on a 460FSB) you're getting more memory bandwidth.

Well, I've tried to overclock it with a lower multiplier and my system would keep rebooting and revert back to standard 266x9.

Man, I can't believe I'm having problems again with overclocking a core 2 duo.

If you would try PC 8000 gskill memory, you might have better luck. Or PC 8000 Crucial (DDR 1000), I and Duvie have some of each. Works better than any 667 or 800 memory.

i thought the 10th anniversary would at least get me o 3ghz on an e6600....but to no avail

Could be that your RAM wasn't binned particularly highly or just isn't the best of a good batch. Mine does 920 on 2.1V...

I thought all 10th anniversary ram was hand picked and tested though?

would i need to burnin my crucial 10th anniv. maybe thats why its not budging above 333 at all..
