Overclocking (Main Thread)

What’s the point here?🙏If I set memory to SPD and 100, does that just rule out memory as a bottleneck? And what about this: setting the CPU multiplier to 6 or 7 to take the CPU out of the equation... seriously? What good are memory latencies then? Where am I even supposed to adjust the memory and CPU multipliers? Probably the CPU, right?

Look, I’m running an ASUS A8N-E myself, and on my board, the memory divider is located under Advanced -> CPU configuration -> DRAM configuration. You'll see options for 400, 333, 266, and 200. As for the processor divider, that's tucked away under Advanced -> JumperFree configuration -> CPU multiplier. That’s where you handle all those settings.

So, according to the link provided above:

First off, you have to find your maximum FSB. To do this, set your memory to 200 (which is 2x100) and set the CPU multiplier to something like 6—this effectively removes both the RAM and the CPU as limiting factors. From there, you just crank up the FSB until Windows fails to boot. Once it crashes, take that last stable FSB value and multiply it by 0.95. That number right there is the absolute maximum FSB your motherboard can actually handle.

Second, you need to figure out the maximum speed for your processor. For this, you set the CPU multiplier to its highest available setting (in your case, 11x), adjust the Vcore to somewhere between 1.6V and 1.65V for 130nm chips—or 1.50V to 1.55V if you're dealing with 90nm chips—and set the memory to 200 to ensure the RAM doesn't bottleneck the process. Now, start increasing the FSB and stress test it using Prime95 (run the Small FFT test) for 5 minutes after every single increment. The moment Prime95 throws an error, take that maximum FSB you reached, multiply it by 0.95, and set it to that value. Then, run Prime95 for a full 12 hours. If it passes without a single error, congratulations, you've found the max FSB your processor can sustain.

Third, you have to determine the maximum memory frequency. Set your memory to 400, the latencies to 2.5-4-3-7 1T (or just stick with whatever defaults you currently have), and the memory voltage to 2.9V. Set the CPU multiplier to 6 so the processor stays out of the way of the testing. Now, gradually increase the FSB and run tests 5 and 6 in Memtest86. As soon as Memtest starts throwing errors, take the current FSB, multiply it by 0.95, and that is the maximum frequency your memory can actually endure.

Once you've gathered all those maximum values, plug them into that Gogar script, and it will spit out every possible stable combination available to you. Just pick one and apply those settings in your BIOS.

Thanks No123....
I dropped the memory to 100 and now the CPU is sitting at 2463Mhz. It’s running fine now.
Still haven't tracked down that multiplier...
Thanks again.

Just thought I'd show off a little bit 🙂

So, I've got this gainward 7950
Stock settings were sitting at 550 GPU and 700 memory—with voltages at 1.35 GPU and 2.0 memory.
That wasn't nearly enough for me—so I went out, grabbed some liquid silver, and decided to crank up the voltage on both the memory (using the pencil mod trick) and the GPU (via the liquid silver).

After bumping the GPU to 1.55V and the memory to 2.24V...
Here is what I managed to pull:
3D Mark 2006 - 7165

3D Mark 2005 - 12499
http://img118.imageshack.us/img118/2...najvisegs7.jpg

Starting from 550 and 700...
I jumped straight to 731MHz and 831MHz.

Card temps under load used to hover around 54 C—now they hit a max of about 69 C.
Still nowhere near critical temperatures.
I might just push even more voltage into it.😁

Can anyone give me a hand with overclocking my GPU?
My Gigabyte GV-NX66256DP turbo force edition (6600 with 256MB RAM and a passive cooler)
The current clock speeds are sitting at 450/500
I've got v-tuner2 for software overclocking, but I was wondering if I could swap in an active cooler. Any recommendations? (I can easily pick up a Zalmani 7000B, but would that be overkill in terms of size and weight?) Also, does anyone know how much performance I can realistically squeeze out of this while keeping it stable?

The rest of my rig: AMD Athlon 64 3200, a Gigabyte K8NF9 motherboard, and 2x512 MB of RAM...

Thanks!

Let me set you straight on that... the Zalmani 7000 series and up are actually designed for CPUs. If you're looking at graphics cards, you need to be looking at the VF 700 or VF 900. Provided your card has the extra mounting holes, you'll be able to use either the VF 700 or the VF 900. As for software, if you want to overclock NVidia cards properly, Riva tuner is the gold standard. Honestly, I’d also suggest picking up ATI tools; it features an artifact scanning tool that can actually pinpoint the maximum clock speeds for both the GPU and the memory.

For two days now, I have been trying to increase speeds by adjusting the bus speed (NS-SB reference clock 100-500), but I am failing completely. I am a total beginner, so I am likely making mistakes. My multiplier is at 11, which is my maximum. My memory consists of 512 MB x 2 DDR2 Kingmax semiconductor KLCC28F-A8KB5—please tell me immediately if this is any good. My motherboard is a Gigabyte C51/MCP55, running the latest BIOS, and cooling is provided by a Zalmani 7000.
I can only raise the FSB directly up to 2750 MHz; beyond that, the system won't boot even after maxing out the CPU voltage and other voltages.

CPU frequency - auto
PCIE clock (NB) - 100-200 - currently set to auto, which is 100
NS-SB reference clock 100-500 - I am attempting to raise this, but nothing happens.
PCIE clock (NB) - set to auto, which is 100 CPU
CPU clock ratio - 5-11, currently set to auto, which is 11

DDR2 overvolting ranges from 0.1 to 0.7. How high am I allowed to push the memory voltage? Since mine are showing 0.3-0.7 in the red, it seems dangerous.
My maximum CPU voltage is 1.550V; is that perhaps too weak?
The power supply is a raptoxx 550 w 1,3

In these settings, is my FSB equal to my DRAM? It shows a CPU/7 ratio. My BIOS doesn't offer an option to show ratios like 4/3 or 2/3 so I can set them manually, or does it work differently?

Memory is listed as DDR2 dual 1024 MB when read via CPU-Z.

Frequency is 315 or somewhere near there; I might have to restart the computer.

FSB/DRAM 7
CAS LATENCY 5.0 CLOCKS
RAS TO CAS DELAY 5 CLOCKS
RAS PRECHARGE 5 CLOCKS
CYCLE TIME (TRAS) 15 CLOCKS
BANK CYCLE TIME (TRC) 21 CLOCKS
COMMAND RATE 1T

The processor is an AMD Athlon 64 3200 athlon64 x2 dual Core 4200+ WINDSOR socket AM2.

Please help me. I cannot figure this out. I have searched everywhere, but nothing works. I will be right here if I need to explain anything further.

Thank you.

Man, this is rough. Look, if you're serious about overclocking, start by grabbing some decent memory like OCZ (even Ve-Mil has their new OCZ line now). You aren't going to get anywhere with Kingmax or that kind of stuff...
If we're talking DDR1, the OCZ Platinum Revision 2 is king. For DDR2, definitely check out those OCZ SLI-ready modules—they absolutely crush it.

Anyway, take a look at these reviews:

Everyone either uses them or swears by them! :-)

I stumbled upon this really cool site today. It looks like an American project dedicated to all things hardware, 3D modeling, coding, and more. It feels like they're just getting started, but I have a feeling it's going to be something special if they keep this up 🙏 www.life4tech.com

I just picked up some liquid nitrogen—thinking about messing around and using it for a CPU sub-zero setup—so I’m wondering if anyone knows how dangerous this stuff actually is to work with. I’ve already pushed my processor from 2.53GHz up to 3.13GHz, and since I’m running liquid cooling on my rig right now

thx

Just mount an 80mm fan on top—one of those standard ones for $10. Try overclocking it first to see what the temps look like. Once you see the heat, slap that fan on there. You could even run it at 5V and that should be plenty.

So, I was looking at these two options and wondering which one actually holds up better: the Club 3D NVIDIA GeForce 7600 GS with 256 MB, featuring both TV-out and DVI, or that Gainward Ultra/1960 TV/DVI "GS" model with the GeForce 6600 GT and only 128 MB of memory.

A bit dated, but this still belongs here:

Intel Pentium 4 @ (2 GHz) => 2.4 GHz
1 GB DDR400
ATI Radeon 9550 (250 MHz, 200 MHz) => 300 MHz, 250 MHz
ASRock K7NFORCE2-RAID
I’m wondering if anyone else has worked with a similar setup, and more importantly, whether there's any room left to squeeze out a little more performance.

9550 at 313 and memory at 212........
What clock speed are you running???

RivaTuner v2.0 Final Release
I can manage to push it up to about 320, but that’s really my ceiling. Other than that, everything is running rock solid.

Here’s how the temps look under a full 100% load—I am a little concerned about the hard drive: http://i167.photobucket.com/albums/u...sa_88/temp.jpg

So, what are you using for your overclocking?

The sensors are lying. Ever tried checking things manually with your own hands?

People lie, and sensors fail.

The main thing is you're fixing my massive screw-up here.🙏

I've been trying to overclock using those old ATI tray tools... but I'm having zero luck getting this GPU to budge. Maybe I'll give Afterburner a shot instead.
My rig is sitting in a secure setup and I can push the CPU up to 2450MHz max, nothing higher than that...
The multiplier is at 11, memory is running at 200MHz, so I've got the CPU and memory at a 1:1 ratio. Latencies are set to 3-3-4-8 2T. Is there anything else I should tweak? Something is definitely bottlenecking me. HELP!!!! Please

Alright, I'm overclocking my GPU...
Core is at 325, memory at 220.... When I tried bumping up the memory, some green and purple dots started popping up on my screen. How do you guys handle overclocking? I usually push the core first, then the memory...

northerncrane33 said:When I tried overclocking my memory, some little dots started popping up on my monitor—green and purple ones...

I'm seeing this too, but only while I'm gaming. It doesn't happen in macOS.
I've got a 9800SE running as a 9800, just updated the drivers, but I haven't touched the memory or core speeds yet. Is it possible one of my pipelines is shot? That would explain it... but since I'm such a total noob at this stuff, maybe someone smarter here has an idea?
