Noob OCing AMD X2 4200+ on stock cooler

post #1 of 4
Thread Starter 
Hi guys:

Im in kind of a problem here. I have an AMD X2 4200+ (89W ver) AM2 + MSI K9N NEO-F. Recently I bought a pair of 1gb DDR800 OZC PLAT ED REV2 memories. After checking CPU-Z and Everest I realized that the memories wont go over 368mhz DDR737....

I accessed the BIOS and saw that everything was rightly configured. After some googling I came along those MEMORY DIVIDER TABLES and (sadly) realized that my CPU cant run those memories at DD800 on stock FSB....

So, after doing some research I came to the conclusion that OCing the CPU to 2400mhz (stock is 2200mhz) would allow me to use my DDR800 mems as they should be working, that is 400mhz each and not 368mhz.

Now, the problem is, that after putting together the rig, Im without money. I mean broke, zero, "nada", nothing not even to buy a coke.
So Im working on stock cooling and AFAIK my mother doesnt allow me to change Vcore so Im also stuck in stock voltage.

My CPU is suppossed to run at 2200mhz to Im going to OC it to 2400mhz. The question is: Is it safe to do it on stock cooling and voltage?

BTW: I have a nice case and a nice PSU. Case is thermaltake Xaser series, nicely cooled, about 5 90mm fans, and PSU is PowerColor 500-SS. About 20Amp on each 12V rail.

Thx in Advance

Make sure that AMD's Cool 'n' Quiet is turned off because that may be the cause of the slower speeds. As far as overclocking on stock and stock voltage, go right ahead as long as temps are okay and you are stable. You always want to see how far you can get with stock voltage, the farther the better I am on stock cooling and i got from 200Mhz to 310Mhz FSB is no time, the core is at 1.45v btw.

a 200mhz overclock can easily be supported on stock cooling on the AMD X2s.
you can go up to 300mhz OC, then you will start seing temperatures rise slowling. at 300mhz you may need to increase the voltages so you might wanna stop there and wait til lyou can afford better cooling.

It's all about the temps my friend, if the temps are good to you, go higher and higher. Also use Orthos to test the temps under load. Idle temps may not tell you much but if you start playng F.E.A.R and temps spike up to 70 degrees....

Facundo,

I agree with the previous responses; you should be fine to overclock your AMD 64 X2 4200+ AM2 from 2.2 GHz to 2.4 GHz. A good review on overclocking this processor can be found at: http://www.legitreviews.com/article/373/1/ In this review, they were able to overclock your processor to 2.776 GHz at stock voltages and stock cooling (disclaimer: they had the parts in open air, i.e. no computer case). In fact, increasing the voltage and improving the cooling only gave another 200-300 MHz beyond that, so you should be able to get a decent overclock with what you have now.

Remember that the memory controller is actually on your AMD processor, so increasing the HTT (also called reference clock on many motherboards) will not only overclock your processor, but also the RAM. So increasing the HTT from 200 (your current setting) to about 219 (the setting that will give you about 2.4 GHz) will also overclock your RAM from 733 to 800, but I think you understand this. It also means that increasing the HTT beyond 219 will overclock your processor AND your memory to even higher values I say overclock it as much as you can, to the setting that consistantly gives you stability and keeps temperatures below 60 degrees Celsius.
