i7 950 Multiplier Question - Page 2

post #11 of 19
Different boards and chips have different nuances with multi. Some may like 19 or 21, but not 20. Some boards may not like 200 BCLK, but like 201 or 202. Also, the RAM thing. Lots of people wait to OC RAM last and OC straight CPU first. So running at 2:10 may better keep your RAM out of the situation than 2:8 or 2:12.

You paid for HT, so I recommend you turn it on and use it.... Otherwise, it's like you bought an i5 760 (worth $100 less than an i7 950).

Here you go;
for 4.0 Ghz (WITH HT)

Well because many people (myself included) like the 200 BCLK Frequency. Though I only use it with a 21x multi (for a 4.2 Ghz overclock). For a 4.0 Ghz overclock, I would still recommend 175 BCLK*23 multi.

In all honesty I would worry about having it past in IBT unless your folding 24/7 run realtemp stress test small ffts. If you pass that test go ahead and use the pc as normal if you don't get a bsod then your good to go. Your vcore seems high. Just my .02 cents.
