Overclocking my CPU and GC

[Gunny04]

Let me guess stock cooler right? 36C isnt where I'd like my comps idle to be, For GPU I use Coolbits (Basically a registery entry download) and it unlocks the overclocking in the drivers themselves..... as for the processer, I think thats in the bios with the Vcore, voltage, FSB and all that, I wouldnt know, my bios is all locked up tighter than a bank vault but I have used 3d party overclocking utils before to crank up a system, to bad that was only 300 Mhz lol,

Anything to do with overclocking always worries me...

If I want more speed, I generally upgrade the components and stick to standard clock speeds......!

Hiya, let's do this in order

1. Overclocking is only dangerous if you do it WRONG. The only thing that can actually damage components is putting too much voltage through them. Overclocking does require a voltage increase sometimes, but as long as you're careful to not go above a certain voltage, you'll be fine. The worst that can happen is the system won't boot, and a CMOS reset is necessary.

2. The RAM (on a 1:1 divider, more about this in a sec) runs at double your Front Side Bus (FSB) speed. On your PC, the default FSB is 200mhz. It is the FSB that is increased to allow overclocking. However, this means the speed of your RAM is increased too. This faster running RAM performs better, but it can only cope up to a point. This is where the quality of your RAM comes into play: how high a frequency can it run at, and at what timings?

A divider is used for RAM that can't handle the FSB speeds being thrown at it. Say your FSB is overclocked up to 300mhz. This means the RAM is running at 600mhz, but it can't cope. What's called a "333" divider, runs the RAM at a 333:400 ratio. 333/400 = 0.8325. 0.8325 x 300 = 249.75. 249.75 x 2 (its double FSB speed) = 499.5. So on the 333 divider, your RAM will run at 500mhz.

Basically this means that even if your RAM is pants, you can still overclock by sticking a divider on the RAM.

3. The Asus AI NOS Overclocking is pants. Just don't even bother, seriously

4. Google Coolbits for the graphics card Overclocking tool. Otherwise, you should have an option for setting clock speeds in the advanced tab of the display properties dialogue box.

As a side note, the 3700+s are known for being astonishing clockers. Mine runs stable at stock volts and stock cooling at FX-57 speeds - ie. 2.8Ghz up from 2.2Ghz.

Hope that helped a bit!

I'll put this in a seperate post; the other one was getting a bit cluttered.

Overclocking the 3700+ in 7 easy steps:

1. Reboot and press F12 at the Asus logo screen.
2. First set the overclocking profile to MANUAL.
3. Set the vcore manually to 1.4V (auto can fluctuate a lot).
4. Set the HTT Multiplier to 4x (from 5x)
5. Set the RAM to a 333 divider (208Mhz @ 250FSB)
6. Set the FSB up a bit, you could try 230mhz or go stright for 250mhz (from 200mhz).
7. Reboot, done

Edit This is specific to YOUR system. And it also assumes that your 3700+ can handle the FSB at 250mhz (giving a CPU clock of 250x11 = 2.75Ghz). Whilst most can, yours might not. That's why I suggested going for maybe 230mhz FSB to start with, then keep upping it.

Once you reach the limit, you need to start increasing voltages to get higher clocks. This is a really basic guide, for advanced stuff like voltage increases, try a google search for Overclocking Guide, etc.

If the system fails to boot because of overclocking, resetting the CMOS will put everything back to default: how to do this is in the manual.

Now please do it for the 4200+

Now please do it for the 4200+

Same concept. Half the fun of overclocking is just playing with your settings

Same concept.

Precisely. The 4200+ has the same multiplier (11x) as the 3700+, it's just dual core.

Follow what I said above, should work fine. Be aware though that the dual cores don't generally clock as far as the single cores, as the duals are built on E6 silicone which is not as good as the E4 silicon that is in (most) of the single cores.

You should get 2.6Ghz easy on air/stock volts/stock cooling.

Just give it a shot. Leave voltages on stock (at least for the moment), and you can't go wrong

My 3800 X2 is E4.

My 3800 X2 is E4.

Yep, there are some mixarounds. I was being very general in that post

I hope you're overclocking that thing, should overclock like a dream that one!

overclocking an Nvidia card is so simple.

download the coolbits registry entry

install it by double clicking it

open up ur nvidia control panel

go to clock settings

adjust run 3dMark continune until maxed out or temp gets to high of ur get random blips on 3dmark

i bought a 7900GTO and i now have a 7900GTX

john

and next my CPU which me and my mate are doing on wensday

[cheesegrater]

A 7900GTO has a 7900GT core. Although the core is already clocked to GTX speeds with GTX heatsink so it's worth it.

[Mees]

I'm fine with having a stock GTX, thank you

A better utility for Nivida is NVTRAY. It allows you access to all the settings and adds access to OpenGL and DX settings your Nivida panel does not see, such as D3D LOD calibration... it should always be set to -6 for best image quality.


You must have NET Framework 2.0 and all the updates for it installed before installing NVTray

The beta version is stable and works better than the official release

coolbits serves me jsut fine thank you nick

but yeh coolbits is probably your safest and easiest bet for overclocking
