mulitpliers on core 2 duo

nvm. i see. this one site says that intel fsb's (sorry, the "core clocks" are in GPU's, right?) are "quad pumped" meaning that they send 4 instructions per clock. so he's dividing the effective fsb to get the core fsb and then adding to that. so the e6320s are 1066 efsb, which equals 266.5 actual. multiply that by 7 and u get 1.865 ghz. i totally understand this now. however, even if you increased the actual fsb from 266.5 to 273.5, wouldn't you still get a .490 increase?

and wow. the effective fsb of 1066 increases at the same ratio of the ram when put under a 1:1 ratio? am i getting this right now? close?
 
ok. but in order to get to like 2.4 ghz on an e6320, youd have to increase the fsb by 100 right? wouldnt taht make the effective fsb 1466? the motherboard is able to handle this?
 
i know. i'm just saying that the mobo is rated for 1066 ghz and the ram is set to 800 ghz. both of the components can actually withstand such high increases in their fsbs?

the mobo is getting like a 360 increase and the ram is getting like an 180 increase in fsb. thats taking ddr2-800 ram past ddr2-1066 speeds...

(now i finally understand why like 80% overclocks are so impressive.....)

You would have to have good ram to do that, what you can do is set the ram divider to something different. Like 5:6 which would make the ram DDR2-888 or something along those lines.
 
OKay. But the mobo would be fine, right?

And also, with multipliers, since they are locked on the chips, what are the benfits of having a lower multiplier and having a higher multiplier? I understand a lower mulitplier would overclock your ram more, right? But wouldn't this be bad in some conditions?
 
ok, jw. with the e6320, the fsb runs stock at 266.5 mhz aka .266ghz. ddr2-800 ram runs at .4 ghz stock. how is it possible to match these up together?

and another scenario. if you oc an e6320 to 3.5 ghz, wouldnt that make a 2000 mhz fsb speed from the chip to the mobo? (1066/4 = 266.5 which is the core fsb on the core 2 duos. 500 x 4 = 2000.) is this safe to almost double the fsb in this case? the mobo would be able to handle the strain?
 
It is much easier dealing with Mhz instead of Ghz. Let me explain this one.

Stock 6320 running DDR2-800 memory
-CPU Speed: 1866Mhz
-CPU Multiplier: 7X
-Front Side Bus: 266Mhz (or effective 1066)
-Memory ratio (FSB:MEM): 2:3
-Memory speed: 400Mhz, or DDR2-800

6320 overclocked to 3.5 (unlikely, but maybe possible):
-CPU Speed: 3500Mhz
-CPU Multiplier: 7X
-Front Side Bus: 500Mhz (effective 2000)
-Memory ratio (Assuming using lowest ratio available on 965P motherboards): 1:1
-Memory speed: 500Mhz, or DDR2-1000

The general way you show your overclock would be
FSBxMULTI

Which would be 266x7 or 500x7 respectively.

The Gigabyte GA-965P-DS3 and the ASUS P5B are both great overclockers, some have gotten to 525FSB. Generally, hitting 490 is going to be hard, 475 might be a good limit for those motherboards. With those speeds, you are going to be putting a lot of extra voltage into the NB. You can use a large fan blowing directly on it to cool it. Other motherboards are going to be less overclock.

The motherboard will, if it isn't too much heat or Voltage. Is it good for it? Probably not, but that's for you to decide.
 
Thanks Jet. And sorry for working in ghz i guess. Just less typing if i can write .4 instead of 400 i guess. IDK. lol.

After reading that, i'm trying to decide whether i want an e6320 or e6420. I really dont want to overclock anything extremely high and even putting the e620 to 2800 mhz wouldn't be overclocking the ram at all, unless using a ram ratio/divider.

I still don't understand something tho,

does the motherboard set up an automatic ram ratio when you put both components in on stock?
 
nevermind. i was asking about how the default settings were configured.

but id idnt wanna make a new thread to ask a simple question sooo....

does this seem possible/like a good oc? (i juss ordered my new rig's parts and am thinking about overclocking.)

lowering the multiplier on the e6320 to 5 and increasing fsb from 266 to 450 (almost double :[ ) with ram on a 1:1 ratio. cpu runs at a low overall speed compared to what other ppl have done at 2250 mhz and ram at ddr2 900 settings.

sound good or is the fsb too high?
