CPU able to use 1333mhz?

August 3, 2009 at 07:28:55
Specs: Windows Vista Ultimate, 5.0 GB
I was wondering if this CPU is able to handle a 1333mhz bus? I am running it in my 780i and to be honest the ghz number (3.73ghz) is nice but it runs crappy. The CPU is rated at 1066 but I wanted to clock it higher, the highest I could get it to was fsb 1200mhz. I am going to buy a new cpu that supports higher bus sizes. What do you guys recommend? My mobo says 1333mhz on the side, why would they bundle it with this cpu?

You've given us very little to go on. Which 3.73GHz CPU do you have? P4? Which board? How about listing your specs in detail?

Are you an experienced overclocker? You realize that you can't simply increase the FSB from 1066MHz to 1200MHz or 1333MHz without tweaking numerous other settings, right?

"My mobo says 1333mhz on the side, why would they bundle it with this cpu?"

A better question would be, why would you buy it?

EDIT: I just had a look at your other thread. What did you do to get that situation straightened out? No details on the CPU, RAM or PSU in that thread either. Doesn't appear to be a very good configuration from what I can tell though. What were you shooting for...gaming?

Let me specify.

The cpu I have is a Intel Pentium D Extreme 3.73 GHz. The motherboard I have is a XFX 780i SLi. It came in a bundle together for $200 and I could not pass it up. The CPU is 1066MHz FSB but I wanted to run it at 1333MHz to match the motherboard. I am running 8GB of corsair gaming RAM. I just want to know if I can overclock the CPU to 1333MHz FSB. I am guessing I cannot which leads me to another question of what CPU should I put in it to achieve the 1333+ FSB.

"It came in a bundle together for $200 and I could not pass it up"

You could have passed it up. Have a look at where your CPU rates on this chart (I'll give you a hint...scroll way down):

http://www.cpubenchmark.net/cpu_loo...

You would have been better off with one of the new Pentium dual core CPUs (based on the Core 2) & a board based on the Intel P45 chipset...you could have easily overclocked that combo to 1600MHz FSB. It probably would have been cheaper too.

"I just want to know if I can overclock the CPU to 1333MHz FSB"

I don't know if you can or not? I asked if you are an experienced overclocker & based upon your non-answer, I would have to guess - NO.

The XE is unlocked so you're free to set the multiplier at whatever you want. The default setting is 14 x 266MHz. If you were to simply increase the CPU frequency to 333MHz (1333MHz FSB), the clock speed would be 4.67GHz which is WAY too high. However, if you were to lower the multi to 12x & raise the frequency to 333MHz, the CPU would *probably* run at 4.0GHz. I say "probably" because you would have to know what other settings need to be changed to be able to pull it off.
