EDIT: Nice post Mootin, although he wont be able to run 2-2-2-6 but 2-3-2-6
oh


you could also look for a vdimm volt mod if you think you need more volts

althought i dont really think you need it imo

A VDIMM Volt mod would be one option but it would probably not be worth the hassle esp if your not very brave about soldering and such.

In my opinion your VDIMM Voltage will be the thing holding you back. I would get them stable at DDR400 and use dividers for your overclock.

with ch-5 ( bh-5's older bother as such ) ram chips usually maxing out at around 230mhz at 2-3-2-X you will be fine just running 2.8volts through it

you might get lucky and reach aroubnd 250mhz as ch-5 has been know to reach those speeds rarely

BH-5 was the first in the line followed by CH-5 a short while later.

To obtain any where near 250MHz you will need much more voltage than you can give them. They require even more voltage than my BH-5 for the same operating speed.

yeh i edited it a while ago i got mixed up


hmmm i heard they require less voltage as anything above the 3v mark doesnt really help , you seem more experienced in this than me so i reckon your right

Well you are partly correct

They can not handle the same amount of voltage as BH-5. CH-5 IC volt spec is 3.1v the BH-5 IC volt spec is 3.6v so yes CH-5 like less voltage, but require more volts for the same speed as BH-5.

for instance you might have something like this:

BH-5 @ 200MHz, 2-2-2-5 = 2.7-2.8v
CH-5 @ 200MHz 2-3-2-6 = 2.8-2.9v

What i meant was, put everything to stock(default), reset your BIOS!
Now don't touch you timings, resist the temptation for now, simply keep raising your FSB then checking how many MHz are on the RAM when you sign into windows and open up your CPU-Z, keep going until you can't boot then reset BIOS again and then you know how far your RAM will go on stock voltages and stock timings.

This will give you a good idea of pretty much how far it will go, obviously if you put a little more volts into them you could go slightly further but not majorly!
