Just set the Vdimm to 1.9v, what board and memory are you talking about, that'll clear it up. :)

[<O_COOL>]

Thanks heres the board:
Msi AMD 790FX-GD70
http://www.take2.co.za/electronics-m...3-4405737.html

and the memory:
Corsair XMS3 DHX DDR3-1600 4GB (2X2GB) CL7

[Ch@pS]

That should be fine, although you'll need to manually set the RAM speed and voltage to 1600, 1.9v respectively.

[<O_COOL>]

Why? Is the RAM not already running at 1600mhz out of the box?

[Ch@pS]

Nope, you'll have to set the dividers right, and possibly overclock your HT bus or whatever its called on AMD motherboards, the board suppoers 1600mhz(OC) which means its cant run that speed at non overclocked speeds.

[<O_COOL>]

Ok thanks. Forgot to read that part ^_^

Hey guys, I recently bought a 250GTS, and it's great.

So, i thought i may just want to overclock it just the slightest bit, but quite frankley i have know idea what I am doing, so therefore I have posted screen-shots of the program (which cam with the card) to overclock.

Please tell me what I should do. Linky

Its simple, really, Use the sliders on the program to set the GPU to 788, the shaders to 1386, and the memory to 1150. A 50Mhz overclock should be possible in all three ranges. Then click "Test". If it runs fine, click "Apply" and find a game to test with. If it runs smoothly after an hour of play at settings that the card can handle, then its a successful overclock ^_^

Hey all overclocking pros, I want to overclock my computer but I have never done overclocking before, do you have any tips for me thanks ;)

My specs: Elitegroup 945GCT-M2 motherboard, 9500GT, 3GB 667Mhz ram, Intel E2160 Dual Core 1.8Ghz

My specs: Elitegroup 945GCT-M2 motherboard, 9500GT, 3GB 667Mhz ram, Intel E2160 Dual Core 1.8Ghz

E2160: Specific Guide, General Guide, General Temperature Guide.

You need to head into you BIOS on your motherboard, but I don't know much about the 945GCT-M2 and how well it can OC. I do know that the E2160 is a nice chip to OC, like any other E series chip. If you do things properly, you can get a stable 2.6GHz clock speed with your default cooler.

As for the RAM, push it to 800MHz for better performance.

To learn how to use your BIOS, download the manual for the motherboard from Elitegroup's website.

After doing a bit of research, it doesn't have many OC options, but it should be fine for a first time OCer.

I know I'm gonna get slaughtered over this, but if you buy this months issue of PCFormat, you can get all the nice CPU freeware monitoring tools without having to download them.

Hey you guys I have a 2.4 Ghz Intel processor en have managed to overclock it to 3Ghz, but i'm still young and my parents aren't willing to pay for a new CPU (or RAM,GPU) if I burn it out by oc'ing it. What is a safe temperature for the CPU to be at. Any help very much appreciated

For a Pentium 4, any temperature under 60 degrees at idle is fine. Under load it shouldn't exceed 80 degrees. By the way, I have an older Intel Celeron 2.4Ghz, and in one afternoon I pushed it to 3.2Ghz with the stock cooler 0_o

what would be a good add-on cooler for an intel Q8400?

[@@GJC@@]

So if my CPU wat hovering around 60?C under load I can still push it a little big further. Will try this

[Lysis]

I am trying permanently overclock my Inno3D GTX 260 and I have encountered a barrier. Anything over a 5% overclock produces either artifacts or below average performance. Now I know that these issues are not caused by overheating as the card temperature stays at the usual 40 degree mark. Could it be that my power supply is to blame here? I am using Rivatuner to overclock btw.

I have an intel core 2 duo e7200, 2.55ghz, what would be a safe over clock?

[RaptoR]

Just a bit of a noob tip but there may be noobs here anyway :
When over clocking try avoiding the voltage of the CPU as its more dangerous to mess around with the voltage than the CPU multiplier and the frequency...I overclocked my 2.6ghz cpu to 3ghz without touching voltage, although i only have a stock cooler so i decided to just keep it at stock speeds, especially since i game for extended periods of time!! :D

I Have an Intel 2.4Ghz processor and pushed it to 3.2 Ghz with the temperatures staying at +- 60? with the stock cooler. You should be able to achieve an even higher clock speed. Just be careful not to overdo it as it may lead to a lag in performance.

The Temperatures at Idle, as Wesley said, should not be over 60?C and the temperature under load should not be over 80?C

Good luck dude. Most Pentium 4's I've played with can go to 3.4Ghz. I once played with one at college that reached 3.8Ghz on stock air cooling.

Na, you just have a GTX260 that won't budge at all.

3.4Ghz should be attainable with stock voltages and the stock cooler. You could probably get to 4Ghz with a better cooler and motherboard.

I second this, but overvolting happens a lot less these days. You can ask Ch@ps, its not that easy anymore. Most processors fry themselves at voltages of more than 1.575v, and you'll find that the majority of processors available today operate at stock voltages of 1.3v, so there's a decent amount of headroom for a bit of error here and there.

[@@GJC@@]

Is it possible that while overclocking, if you push your clock speeds to far, can the performance be influenced negatively. Or, if this happens, does it only happen because the CPU doesn't have enough power in other words the voltage is set to low????? Any help appreciated!!
