attempting to overclock AMD single-core

October 27, 2012 at 16:15:38
Specs: Vista, Duotronic IIa/5096 gigaquads
I have a computer with an AMD Semptron single-core processor running at 1.8Ghz factory set. Has 64K L1 cache, 128K L2 cache. I would like to over clock it to 2.4 if possible. It runs crappy with an non-upgradeable intergrated graphics card (uses regular RAM for memory). I have Bios numbers if u want them.

P.S don't worry about overheating, it has a MASSIVE cooling heatsink and fan! Never runs over 115F in a 75F room.
P.P.S I've gleaned from other posts that over-clocking a single core is long-term suicide. is it really that bad?

Long term suicide? Possible but your Sempron has one foot in the grave now...I wouldn't sweat it.

What's your motherboard? Or is it a manufactured (Hp,Dell, ...) system?

No board listed, no RAM listed, we don't even know which Sempron you have - socket A, 754, 939, AM2, etc.

"It runs crappy with an non-upgradeable intergrated graphics card"

Uh, that's why the motherboard has slots for upgrading to an actual graphics card. Integrated is NOT a card.

OK, Ok, i showed my total noob-y-ness there. Sorry! Here is specs:
processor: AMD Sempron Processor 3000+
Speed: 1800Mhz
L1DC size: 64Kb
L1IC size: 64Kb
L2 size: 128Kb
CPUID: 10FC0
Socket: 754

RAM: 448Mb DDR, if I am reading it right 400 Mhz bus speed.

Motherboard: ASUS K8V-MX/S Rev. 1.06 (too many numbers to tell but this is the one I think is the model)

Now that you have my specs, here my REAL noob-y-ness comes out: could you tell me how to overclock it? i never figgured out how to overclock...

To riider: I KNOW that! i typed it wrong. Besides, when I was digging around in the BioS (i know, you're not supposed to do that) i found a setting that allows graphics to take 256Mb of shared RAM instead of the original 32. Slows down non-graphics programs, but graphics programs work like a charm!
To Skipcox: oh dear... *bites nails*. Oh, BTW, it's manufactured by Cisnet.

P.S Now that you mention it, it has an extra AGP slot. Maybe i'll buy an upgraded card to go with my over-clocked processor...

The downside to your CPU is that it only has 128k L2 cache. The "good" Semprons have 256k L2. The Athlon 64 has either 512k or 1MB L2. In other words, overclocking will improve performance somewhat but it can't make up for the lack of L2.

I don't know what options are available in your BIOS but here are some generic overclock settings that might work (VIA based boards aren't the greatest for overclocking):

HT Frequency = 600MHz (or 3x)
AI Overclocking = Manual
CPU Multiplier = 9.0x
CPU Frequency = 250MHz
RAM Frequency = 333MHz (or 166MHz)
AGP Frequency = 67MHz
Spread Spectrum = disabled
CPU voltage = 1.45v **note: you may have to increase the voltage to stabilize the overclock. If necessary, increase it 0.025v at a time, testing for stability after each change.

Assuming the above settings work, the CPU will run at 2.25GHz with the RAM at approx 408MHz DDR (204MHz) & the HT Frequency at 750MHz. If the system becomes unbootable, simply use the clear_CMOS jumper to reset the BIOS, then start over.

1: I understand everything else, but what is HT freq.?
2: I can't find any of those settings except the RAM clock in my BioS. here is BioS specs, if they help:
Version: 08.00.09
Revision: 1008.010
Build Date: 05/12/05
ID: A0023010
maker: American MegaTrends, INC
Could you manually put these settings in somehow?

No. This appears to be a system integrator or OEM motherboard (K8V-MX/S) and ain't supported by ASUS. That's what the "/S" means and it's a different motherboard than the Asus KV8-MX.

My advice...use it as it is. Don't **** with it.

Ok, SkipCox, i'll go with what you say. Now how about over-clocking a PIII? here are the specs from it:
processor: Intel Pentium III
speed: 450Mhz
Front Side BUS speed: 100Mhz
Cache RAM 512Kb
RAM: 128MbSDRAM
BioS Version: 4W4SB0X0.15A.0013.p08
Computer manufactured by Gateway

Did some digging, and I can't find any settings that look like the ones you recommended for the AMD.
~oldie
P.S I can't get the socket number off the CPU. Don't know how to remove the heatsink.

It's a Slot 1. Some of them overclock pretty good.

Yours won't though.

You said Gateway.

The Gatewy BIOS won't give you any of the options you would need to OC.

Chew on this...if you could double the speed (you can't), you still wouldn't have something that would work well in today's world.

My 200Mhz MMX running at 275Mhz won't do a thing it didn't do before.

"if you could double the speed (you can't), you still wouldn't have something that would work well in today's world".
Well, I have a game called Age Of EMpires, ver. 1, and it runs slightly laggy on this system. If I could get 100 more Mhz out of it,I would be happy. Why do you think my forum name is OLDisgood?
P.S I saw in a How-To under CPU/Overclocking that there is a program designed for overclocking. Check it out!

That particular P3 is a Slot 1 cpu. You probably won't be able to overclock it because it's a Gateway system.

Go into the BIOS and look for Bus Frequency, FSB Frequency, System/PCI Frequency or similar. If it's adjustable, try increasing it to 112MHz first.

The 440BX chipset was only officially rated for 100MHz bus operation, but many BX boards could run reliably at 133MHz, so long as the graphics card could handle an 89MHz AGP bus (nearly all nVidia cards could). At 133MHz, the BX will automatically clock the PCI bus at 33MHz, so you won't have to worry about your audio, network, and HDD controllers.

EDIT: Dang, a minute late! :)

I might as well pick you brain while i'm here.

I want to overclock my parent's old 2.4 Ghz P4. I have to dig it out of the basement and find a monitor, (since i got it 2 years ago when they upgraded) and my parent's constantly complained about the speed. I gave it another 512Mb ram boost but still crawls. Should I take a shot at it?P.S it's a OEM system by DELL, so what I have gleaned says that overclocking will be a no-go. However, I remember a CPU speed setting in BioS, now that I think about it.......

EDIT: To Jackbomb; I tried. Nothing is adjustable. I'll just leave it for now.Is'nt there a way to update/interchange BioS chips? Maybe to one that allows ovverclocking?

It shouldn't...runs fine on my old machine at 200Mhz or 275Mhz using a MX440 video card.

You haven't posted the OS in use with any of the systems mentioned. Insufficient RAM may be an issue.

You generally can't overclock OEM systems - Acer, Dell, Gateway, HP/Compaq, etc. The OEM BIOS is deliberately "crippled" to prevent too much user tampering. If they supplied a "normal" BIOS simialr to what's available with aftermarket boards, too many users would experiment with the settings, make their system unstable or unbootable, then flood the OEM support lines with calls.

"I understand everything else, but what is HT freq"

AMD Athlon64/Sempron sytems use totally different BIOS settings & terminolgy than Intel systems. HT = HyperTransport which is strictly AMD. Older Intel CPUs used FSB (Front Side Bus), newer Intel CPUs did away with the FSB & now use QPI (QuickPath Interconnect).
