Overclocking question

post #1 of 10
Thread Starter 
Which is a good overclocking option.
220 x 13= 2.86 or
205 x 14= 2.87?
can anyone give me a small explanation to this please. now i have my cpu overclocked using 205x14 which is at 2.87. which one should u guys think i should do?
thx

The 220x13 will overclock your RAM to 440MHz.

205x14 will overclock your RAM to 410MHz.

It's your pick.

Option 1 puts more stress on the motherboard/chipset, as it's running at a higher HT ("FSB") speed. On the other hand, 220MHz on the HT frequency really is only 10% over stock value, so it's not that big of a bump. Contrast this with an Opteron 165 running with a 300MHz HT frequency; that's 100% faster than stock on the HT frequency side of things! (This yields a healthy 2.7GHz CPU speed, a useful 900MHz increase which is 50% faster than the stock speed of 1.8GHz.)

Option 2 is also a touch faster in terms of CPU frequency.

Which will perform better? Only testing and benchmarking will give a definitive answer.

Hope this helps!

thx i will try that now

Lower multi and higher FSB ftw!
If you just up your multi on the CPU without upping the FSB you are only increasing the speed of your CPU and basically creating a bottleneck effect. I would definitely go with the higher FSB because then you are upping the speed of the computer as a WHOLE(CPU/MEM/MB) instead of just the CPU. Do your benchmarks and you will see

Well, not really. AMD's will gain more from a higher clock speed/FSB ratio, as the mem controllers are internal to the cpu. So memory bandwidth is increased as the cpu is. Latency is by far, something that affects AMD rigs more than Intel too, lowering the multi on the CPU will add more latency. Im sure you can reach a point in the multi/FSB where you are able to overcome the added latency with raw speed, but all in all, I would stick with the higher multi for a more responsive CPU.

Q-> If your RAM can run at 450mhz...then why not just leave the multi alone and up the FSB until you reach that RAM speed? As long as your cooling is up to par, you should get 'the best of both worlds'...faster cpu and mem, without extra latency.

As far as gaming performance goes, it makes little to no difference.

A8N32-SLI Deluxe = Socket 939

Meaning, no AM2 processors will slot in (different socket types).

As far as dual-core CPUs, the answer to this part of your request really depends on how much you want to/can spend.

Hope that helps you.
