is $100 in ram worth the extra ~400MHz CPU OC?

So my mushkin ram doesnt want to go over 800 MHz, unless im doing something wrong. so i am contemplating getting DDR2 1066MHz ram to take my 3.6 OC to about 4.0 or 4.2 GHZ is it worth the money for me to do this ? im hesitant so thats why im asking...

I tried different voltages and timings and it just does not do it, from what i understand i would need to go to 444MHz x 2 in order to get to 4.0 GHz on my E8400

cheapest 1066 ram on newegg.ca is about 79.99+tax + shipping
 
I just noticed for some reason in cpu-z under SPD, i see Jedec #1 values different from Jedec #2, thats not normal is it

266MHz 4-4-4-12
400MHz 5-5-5-18

For me, I'd save that money and use it to start building a little upgrade fund that will give you a much bigger performance increase than what you're hoping to get from that.
 
I wouldn't be investing money in DDR2 right now. DDR3 is so cheap, it might make more sense to just do an entire platform upgrade.

It would make more sense if you simply wanted to add more ram. To replace your current stuff doesn't make sense IMO.

I say you should part out your system on FS/FT and then buy something new.
 
Can you lower the RAM multiplier? This would make sense if you were going to do more of an extreme overclock, so you could get the RAM back up to close to 800 MHz
 
You can't do DDR2-888 5-5-5?

Try loosening timings to 6-6-6-18 & bump up vDIMM a bit...i'd be surprised if it cannot do it.
 
why not ?

Looks like one of the rams slots was bad on my mobo, switched ram sticks to opposing slots and got 4GHz

2.1V Ram
1.4V Vcore
5-5-5-18 890 MHz
445 FSB

Prime95 looks good so far. who knows maybe i had a bad voltage controller on one of those ram slots... ;-( weird
 
Personally, I would save the $100. 4.0ghz is pretty easy for most Core i7 CPUs from the i7-920 to the new i7-2600K... and of course those all have four physical cores, a newer microarchitecture, and hyper-threading.

The bigger question is whether or not you need the extra 400MHz. If not, why bother?
