Xp1800+ @ 2.4ghz

[RoD]

With my new pc in the mail, i ahve already began thinking of how to push the thing after i burn it in a little. I have seen some sites claiming to get 2.4GHZ out of an AMD XP1800+ on basic air cooling with nothing much more than software changes in the bios and voltages.

Now my question is, does anyone know of a site with a how to on these? All i can find is results, and overclockers.com forum is down for the count.

My setup is:

AMD XP1800+
Core: Thoroughbred
Operating Frequency: 1.53GHz
FSB: 266MHz
Cache: L1/64K+64K; L2/256K
Voltage: 1.6V
Process: 0.13Micron
Socket: Socket A

on a ABIT KD780 mobo
Chipset: VIA KT400A + VT8235CE
FSB: 333/266/200MHz
RAM: 3x DIMM for DDR266/200 Max 3GB (Include 2x DIMM for DDR400/333 Max 2GB)
IDE: 2x UltraDMA 133 up to 4 Devices
Slots: 1x AGP 8X, 5x PCI
Ports: 2xPS/2,1xCOM,1xLPT,6xUSB2.0(Rear 4),1xLAN,SPDIF Out,Audio Ports
Onboard Audio: 6-Channel AC97 Codec
Onboard LAN: 10/100Mbps Fast Ethernet
Form Factor: ATX


Cooling is air, fully controlled. Not stock cpu fan. Thnx for the help.

If you wanna use air for cooling that you're gonna need a good quality thermal paste based on a silver compound (www.arcticsilver.com has good reputation).
The way to go about o/c a computer is going bit by bit. First, you don't say which RAM stick you have, so if you can, try to go with different speeds with the proc FSB and the memory speed (they're not always the same). On my mobo I can control different speeds for the proc FSB, memory-north bridge and for the AGP (basically all buses going through the north bridge).
The FSB usually affects the south bridge as well (PCI, mainly), so you need to be carefull, if you can't push the FSB higher without risking stability have a go with the multiplier, this will affect only the processor, although it'll heat up a lot.
To keep stability you may need to set the voltage higher, if you do, do it really slowly and bit by bit, always checking the proc temperature, you shouldn't need to put it more than two or three steps, because this can burn your processor without any warning (except the smell of burning, but that's too late). If you need to put it up more, pull back on the FSB and multiplier a bit.
Heat is your enemy, use a quality thermal paste, a good heatsink (copper or better) and fan.

the ram (sorry i forgot) is 256MB PC2100 DDR, 266MHZ.

I ordered this fan and it comes with thermal paste.

Most of what i read on 2.4GHZ was on the OEM cooling setup though so i cant say im amazingly worried about the fan setup i chose. I also ordered a fan-loaded case and a fan control panel.

you are kind of castrated by that ram in your goal of ocing above 2ghrz. without a multi change, you are running at 11.5 x multiplier. So at 2 ghrz, you are talking : 173.91 fsb, double that for ddr , and you have over 333, so, you need to atleast get some good ddr2700 ram, or better yet splurge and go for some dd3200. if you lower the multi, which is what most do for 2ghrz+ overclocks, you are are talking ddr 400 ram if you go to 2ghrz with a multi of 10x.

I seriously recommend you go to:

www.ocforums.com

register, and talk to some people there about your situation, most are glad to help.

Hmmm... crappy motherboard crappy RAM.... I wouldn't expect 2.4 GHz out of that in any way.

If you're serious about overclocking get a good nForce 2 based motherboard such as the Abit NF7 or DFI lanparty. Also, you're going to want to PC3200 RAM, that PC2100 is going to be your biggest problem by far.

Also, I would highly reccomend getting a mobile chip, such as the mobile 2400+ or 2500+. They are basically cream of the crop chips, running at only 1.45 volts by default. Some people are getting upwards of 2.6 GHz on air and a few select are clearing 3 GHz with "slightly" more extreme cooling methods.

the ram is low grade, i admit, lemme see if my card will let me spend more and ill bite the bullet on some better ram. The board is one of the best for the price.

ok im sending newegg's pc2100 back, bought this:

[TravisS]

Yeah, that should be a bit better

Infineon RAM isn't the greated stuff ever, but it's not bad either. My PC2700 Kingston ValuRam uses Infineon modules and can reach PC3200 speeds (200 MHz) with the default timings. At that point I have a feeling it's my motherboard limiting me.

I thought about it, and your motherboard won't be too bad, just don't expect to be running 200 MHz FSB. At that point your PCI/AGP busses will simply be too fast, and you'll most likely get data corruption (at 200 MHz FSB PCI is at 40 MHz, most devices can't handle much over 35).

One of the relatively large factors you will probably run into is locked multiplier. I don't know this for sure about your board, but last I checked not many VIA based chipsets have unlocked multies. You can simply put a strand of wire in the socket to unlock the multiplier though, it's not very hard. Sticking with the default multiplier of 11.5 would put you at roughly 1.9 GHz at 166 MHz FSB. I would guess that you won't be able to get much more than 180 - 185 MHz FSB with that board, so maybe topping out around 2.05 to 2.1 GHz on the CPU, which isn't all that bad. I personally run my 1700 + at 166 x 12, or 2 GHz. It's powerfull enough for most of my needs and it's 100% stable (can go to 2.2 GHz (200 x 11) unstable).

think i can get away with upping the ram a little and changing my vcore on the amd? Supposedly you can hit the 2.4 mark by simply changing the core voltage (vcore)

[EvBladeRunnervE]

vcore does not control the fsb in the slightest, it just provides alittle more oomph to the chip to help it run at those faster speeds. the mobile athlons are extremely interesting, since being released they have become one of the most popular AMD chips do to their inherent overclockability.

>>it just provides alittle more oomph to the chip to help it run
Yeah, but that can speed it up a bit, although you probably won't notice it.
I'm not sure if your matherboard allows you to control the different buses' speed. A motherboard with an nForce2 chipset will let you do it, and they're really nice so I'd recomend getting one.

I know a few people who had nforce asus boards....nothing but problems from the things. I will know what the motherboard lets me do thursday or friday.

I'm debating building the new comp and using the pc 2100 ram to see what options are in the bios, then just letting it be for a day or two till the pc3200 gets here, but i might just hold off and wait for the 3200 all together so the board never has anything slower in it.....or does it not matter?

Actually, i may run everything bone stock with the 2100 and benchmark it, then bench it stock with the 3200, and compare off those when tweaking it.

Also, whats a good FX5200 tweaking program?

[Fountain]

Why not just save up a relativeley small amount of cash and buy a better chip? With all the trimmings of course.

Look what I found: http://www.nvplanet.com/forums/index.php?showtopic=20
The nVidia drivers also allow you to o/c the GPU/memory but I can't remember the switch.

as I said, check out www.ocforums.com . It really does matter even what stepping your NB and SB chips are in some cases. If I were you , I would quickly cancel your entire order and go ask the people www.ocforums.com . Give them your price range, your needs, and there should be atleast 10 people who could help you within a couple hours. Best of all, most of the people there absolutely know what they are doing.
