Intel 660 in need of overclocking!!!

Toggle sidebar Toggle sidebar
There's a lot to know. Basically, in order to achieve higher CPU frequencies, you push the FSB higher. Since it seems you have good memory, that shouldn't be a problem. Give some more (slowly more when it is needed) to CPU and memory to ensure stability. Then when you get a desired amount or hit a wall use Prime95 torture testing for 24 hours to make sure no errors arise, all the while checking CPU temperatures to make sure that full load temps don't exceed 60c. If you are using the stock fan, don't even start overclocking, throw that thing in the trash and go out and buy an aftermarket heatsink. Some recommendations on that note would be Thermalright XP90C, XP90, XP120, Zalman 7700CU, and Thermaltake Big Typhoon, not to mention any water cooling unit.
 
Hey thanks for the reply. I did two days worth of research on a good fan and finally got a Zalman CNPS9500 LED.
The problem is that I dont know my optimal memory timings and frequency, any ideas? Right now its on the "suggested" frequency.

Also, my SATA 300 hard drive doesnt show up as a SATA 300. How do I enable SATA 300?

Finally, how high of a FSB should I be able to get on this comp. Thanks!
 
There are three things you will need to modify.
1.) CPU External Frequency (x2 = FSB)
2.) CPU Frequency Multiple
3.) V-Core Voltage ~ as you reach increase freq and stablity issues arise, increase by .05 volt and retry

The difference between Harleybro and me is: I have a PC-6400 vrs, PC-5300. But he has intel 670 vrs my intel 660. Not much difference, what type of cooling did he use?

Also, I have a SATA 300 hard drive connected directly to my motherboard, but it doesnt run at 3gb/s. Whats wrong?
 
Here are some benchmarks of the Intel 670, a 3.8GHz CPU.

http://www.xbitlabs.com/articles/cpu/print/pentium4-670.html

Compare it to my Opteron 175 at 2440MHz is a bit faster than the X2-4800 being compared, but is sure beat by Intel in this benchmark!

But in this one, isnt it where Intel markets its products as being fastest?

It sure isn't 3Dmark05

I know, yeah, It is in multimedia creation that Intel dominates...

that's BS... you show the benchmarks run by THG, and they'll show you unbiased benches. Here you pick and choose, and apparently they've rigged the benches.
 
Toms, unbiased :lol:

I linked the page, and displayed every gaming bench you twit.
Read and assess, you might learn a thing or two. And these are over 7 months old, today dual core scores better than these show, so I guess it is biased, and is favoring single core chips.
Let me guess, your pissed because you own a single core and believe it to be the ultimate fasted gaming CPU... 😉
 
I have done some research and found that this intel fits my needs pretty good (I would have prefered the EE but that was a bit expensive). AMD is very good at focusing its power so its good for gaming, but I needed something that could do multiple task (including video editing). So I went for the Intel 660.

One problem though, I cant get the FSB higher than 215. I dont know why, I tried uping the cpu voltage but that didnt help. I keep getting this "memory dumping" blue screen. My memory is a Patriot 2*1GB DDR2-800 and its clocked at 4-4-4-12 2.1v. Could it be the mem?
Also, I have a 400watt power supply, is that to low?
 
you could watercool or you could use the ghetto method.water coolin+ dry ice = one extremely cold pc 😀 😀 😀 😀 😀 😀 😀 😀 😀 😀 :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:
 
oh i forgot to say that you would also need to be careful with dry ice it burns your finger's and releases carbon dioxide and too much of it can kill you no joke im being serious! this time
 
How did we go from overclocking my PC to burning your finger with dry ice! 😀 Anyways, you can only burn your finger if you squeeze the dry ice, I've held it and nothing happens.

Anyways, anyone have any idea why I cant overclock to more that 220 FSB on my Intel 660? I gave some suggestions above.
 
rich plz how come intel boards let u oc so high...? is the guy wiht 700mhz fsb is using a 1:2 ratio right? so his ram is at 350mhz.. dont most 939 boards max out at 400fsb in bios?
 
Later models Intel chips use DDR2 which has higher latency's than DDR RAM and also allows them to clock up higher.
I imagine the AM2 may level this as soon as released we will see.
 
what about the voltages to his memory? I'm not sure about DDR2 voltages but 2.1volts sounds low to me, since I use DDR1 @ 2.75 volts. I had a problem booting up at DDR464, so I upped the voltage from stock 2.65 to 2.75 and it booted! :)

windshear, DDR2 stock voltages are far lower than ddr1 recommended voltages. ddr2 starts at 1.8, whereas ddr1 starts at 2.8. i would imagine putting massive voltage in ddr2 would damage the chips.
