The Overclocked Computers Thread

[BIKeINSTEIN]

Noooooooooooooooo...
I came to TBhp for some cars/bikes and you geeks are trying to take over this place too. :P

No Benching rigs Amey- not fair- atleast here.
I think your watercooled rig will be even more welcome than some nerdy OC stuff.
After all it has some parts common to automobiles too.

@Nikhil
As i mentioned earlier, Moralfibre forced me to post this after checking it out on my forum.If i wanted to show off, i would have done it long ago,when i posted on my forum
@ Dinar,
Thanks for your kind suggestions but the kind of temperature drop LN2/DICE gives, i am not sure anything else can,maybe a cascade but thats about it.

Is it possible to fry the cpu? I guess thru some mechanism the cpu will shut down immediately... may be this is a stupid question.

Amey, I bet nikhil was telling it in lighter vein. We have a bunch of show of threads under "modification" section where people go out and do show off.

BTW,
Got a question, For all OC gurus out here. today if i want to go out and buy a system(intel based... ) for my daily use with moderate amount of OC done in(just for the kick of it), with budget of 50k(for the rig alone) what would be the recommended hardware?

I have some idea about cpu OC, but almost zero about memory OC.

[moralfibre]

Amey what I wanted you tell people is how you designed that amazing looking copper pot. You are a mad man!

[Amey]

@ Gkrishn,
Here you go,

Intel C2D E8200 = 8.1k
Thermalright Ultima 90 CPU cooler = 2.4k
Abit IP35-E = 5.6k
2GB DDR2 800 = 1.5k
Corsair VX450W PSU = 4k
Full ATX Chassis of your choice = 1.2k
500GB WD HDD = 5.4k
Samsung/Pioneer SATA DVD-RW = 1.4k
Nvidia 8600GT GPU = 5.8k
19" LCD Monitor = 9.5k
Optical mouse+Keyboard = 1k

Works out to ~ 46-47k

Well within your budget, and extremely powerful well balanced config.

Well within your budget

Old amd cpus did not have that feature. If the heat sink is removed they burn them selfs.

Thanks for that Amey.

BTW this c2d is not a EE. So how to over clock it? Is it by fiddling with the fsb nos? Basically how do you guys go about and start this OC? All i am aware of is, increasing the multiplier of cpu.

Coming back to cost, lets keep the silly keyboard/mouse outside. When I asked the question, forgot to factor in the monitor cost. So it is 40k just for the box...

Nvidia 8600GT GPU <- any specific board in mind?

Is not available in all cpu`s. In Amd FX series, Black Box, And Intel Extreme Edition. Are some of these have unlock multiplier

Yes, thats the reason i asked the question...

EE series CPU is not mandatory for overclocking.As long as you have a board that supports overclocking, you are set.
Overclocking for non EE CPUs is by increasing FSB as you cannot change the CPU Multipler.
Now for example,
8200 has a multiplier of 8x and FSB at stock is 333MHz hence its stock speed is 2.66GHz
now you bump the FSB through Motherboard BIOS to say 400MHz and the clock speed becomes 3.2GHz.
You keep pushing the FSB until your system becomes unstable, then you bump the vcore (CPU voltage) from motherboard BIOS to gain stability.
Thats the way you go about overclocking.This is just basic stuff, there are many things to fiddle around with when you do serious overclocking like VMCH,Vdimm voltages, PCIe frequency, DRAM dividers and so on.

you can go with Gigabyte, XFX,MSI,Asus for 8600GT. All these are good brands.

[Nikhilb2008]

And another thing is, before overclocking, you need to be sure that you have a good Power Supply.

This is over clocking in one line.

Even if the CPU shuts down, the TEC is still at say 300 degrees. That is enough to make a mess of the CPU.

[hyper123]

Umm, what does TEC, EE and FE stand for?

Amey, have you overclocked AMD 64 X2 processors?? How about the 4600+?

TEC = Thermo Electric Cooling
EE = Extreme Edition ( Intel's Top of the Line CPUs with unlocked multipliers)
FE = ??
Did you mean FX ?
FX = AMD's version of Extreme Edition CPUs.

I havent played with AMD CPUs lately.Its been a long time since i did so.The last i Overclocked on was AMD Opteron 170 Socket 939 based.
Here is what i achieved back then, then i clocked only on AIR cooling, no Water/DICE and all.
Even now i have 3800+ and 4000+ but its waste of time, trying to clock them as they wont get good numbers in benchmarks.
