AMD 2000+/ MSI KT4 Ultra

[rcillig]

What kinda OverClocking could I get outa this, Im new to this all so I dont got a clue.... give me your opion.

AMP XP 2000+
MSI KT4 Ultra
768 megs of DDR 2700
Nvidia FX 5200 128mg Viedo card
368watt power supply
40gig 7200 rpm HD
Windows XP Pro


Thanks for your opion and help.

Would you happen to know if you 2000+ is a pally or tbred? If it is a pally, I would expect something in the 1.7-1.9 range, a tbred something like 1.8-2.1 ghz range. Pretty decent settup. You will love that ram. Big step up from sdram. :D

[rcillig]

I downloaded that program Aida32.. ok and it says for cpu i got

CPU Properties
CPU Type AMD Athlon XP, 1754 MHz (6.25 x 281) 2100+
CPU Alias Thoroughbred-A
CPU Stepping A0
L1 Code Cache 64 KB

Ok but i got a AMD 2000+ why does it say 2100+?? when i rigth click on my comp it says i got 1.75ghz.... and ive changed nothing. so why dont it read like a 2000+@ 1.66 or what ever they are...

[Tyranos]

You won't be able to raise the fsb very high, because via kt400 chipsets do not support agp/pci frequency locks.

[rcillig]

ok so what could I exspect to get outa my setup?

[Tyranos]

It depends on if you have a tbred a or b. I wouldn't trust that Aida program if I were you. It says you have a multi of 6.25 and fsb of 281?? lol

[rcillig]

ok then how would i find out if I got a tbred A or B

even that other program I found GCPuid says I got a tbred A

[Tyranos]

Its on the black sticker on the cpu itself. Jiuhb or Aiuhb = tbred B, because it ends in B. Ends in A= tbred A. For a tbred A, I'm guessing generally around 1.9ghz. For a B, generally 2.2ghz or so.

[rcillig]

I understand that but he said not to trust it so I was wondering how i can make sure...

[c627627]

By reading the fourth line of your very own second post.
"CPU Alias Thoroughbred-A"

A's are better than Palominos. A's are unlocked.
They overclock 300 MHz less on average than B's though.

Post the brand of your RAM and power supply.
A's hit average 2.0 GHz.
Expect average 180ish FSB.

[rcillig]

OK..... so how I go about doing this, sorry for all the questions just wanna make sure I understand before i do it

[c627627]

You read your mobo's manual.
You read this thoroughly:

Then you ask specific q if there are any.

[c627627]

In the end, with gradually increasing Vcore to 1.8 volts + increasing Vdimm (RAM) voltage as well if you can, expect maybe 11 x 180-ish FSB for somewhere around 2.0 GHz.

But you didn't post the most important thing - cooling!

There's a difference between all copper Thermalright and other brands, what do you have?


Don't confuse being able to boot into Windows with stability though.
Prime95 Torture test your system for 12 hours without any errors being displayed in Prime95.

i got stock heat sink and fan on the processor cooling with 3 case fans.... what do you recomend?

[treepop]

I think hitting 180 with that mixed ram is very possible.....
I agree with c627627 what kinda heatsink and fan you got?....
368 watt psu where is that # from....sounds kinda like and odd #....maybe it's just me....

but if the cooling is good....I would say 2gHz would be reasonable.....and to be honest youll love the speed 2gHz is essentially a 2600+....I say this because he would proabably be running 180x11.5 which I know is less Ghz less then a 2600+ but it has much more fsb.....so thats where I get the performance rating :)

[rcillig]

ok then Ill chck out my local store for a better heat sink/fan combo cooler then Ill give this a try...

[rcillig]

Ok first off thanks for all your help... now to the point.. I got 2 pc with a 2000+ in them so I checked both...


MY Machine:
axda2000dut3c 92b3925250072
RIUGA 0236mppw AMD 1999


My Girls PC:
axda2000dut3c y837976270706
AIUHB 0317vpmw 1999AMD


So if I understand my GF is a better processor and I should put it in my pc for a better OCing... correct.

what do all the other ## and letters on the processors mean? and what kinda speeds can i get out of it? and colling?? how far can i go with the stock AMD heat sink and fan?

[c627627]

RIUGA 0236mppw is T-Bred A [RIUG-->A<--] made in the 36th week of 2002
AIUHB 0317vpmw is T-Bred B [AIUH-->B<--] made in the 17th week of 2003

They're both excellent for stock speeds.

B overclocks 300 MHz further but you need non-retail cooling for overclocking.

Try to work in a Thermalright heatsink. At the very least the $9 SK6+ but I'd go for the $15.99
http://www.svcompucycle.com/thersk7socco.html

Don't forget a fan, nothing too loud, but pretty much any 80x25mm will do with SK-7.
http://www.svc.com/thersmarcasf.html
Look for cheaper fans if $'s concern.

[rcillig]

Ok Ill get a new fan and heat sink but what kinda speeds you say 300 more but what is that like say 2100..2200 or so.

Ive been testing it and I see the... it was set at 12.5*133 witch is 1.6667

or so I lower the multiplyer value IE 12.5 down to the lowest I can go.. 6
then raise the the fsb up... ok how far do I go.... I understand a little at a time but what would I exspect to get so that I dont try something way to much.

like 11*180 gives me 1981 that is 300 more than stock.
12.5*144 get me 1800

where do i or do i change the voltage? and if so how far?

[c627627]

With good power supply, cooling etc.
T-Bred A averages 2.0 GHz or 2400+
T-Bred B averages 2.3 GHz or 2900+

Sometimes more, sometimes a little less but it helps you see where you would be in relation to average overclocks.

I wouldn't go above 1.80 volts Vcore. Read the mobo manual to see where in bios you would increase CPU voltage.

2.0 GHz is about 180 FSB x 11.

Your RAM and mobo limitations are 180ish FSB.

If you're asking for a guess, expect at the most 18x FSB where x is 0 to 9.

Don't screw around with retail cooling and read the link on how to appply thermal paste carefully if you get a better heatsink. (Thermalrights are the best.)

[rcillig]

Ok thanx Im sure ill have more questions when I get better cooling.

also my vcore is at 1.60 right now I see where to increase it but how far and do I need too?

[c627627]

Oh yes, Do it gradually. And end up with 1.80 V for 180ish FSB overclock.
(You don't want to go straight to 180-something FSB.)

This increases the temperatiure so don't be doing this with retail heatsink.
Don't put too much thermal paste when you you get a new heatsink. Follow those directions:
http://www.arcticsilver.com/arctic_alumina_instructions.htm

Also don't go higher with FSB even if you can since your mobo is not nForce2 with PCI lock.

190 FSB / 5 is 38 that's the safe limit for 166 FSB /5 default.

[rcillig]

ok got ya, when I get a fan what temp is too high and what should it be normally?

[c627627]

When the CPU is under heavy stress, like when you're testing it for stability by running Prime95 Torture test, I'd say low 50's celcius is acceptable.

[maxlaser5]

I have a similar setup: AMD 2000+ Tbred B, Soyo KT400, PC2700 RAM. Since my Soyo does not officially support PC3200, I only set the memory speed to 166MHz, can I change the FSB to 167MHz - 180MHz while keeping the memory at 166MHz? I tried to run the memory at 200MHz and it just won't boot. Thanks.

[c627627]

In your case maxlaser5, you have PC2700 RAM.
Here's what that means:
http://www.pbase.com/image/19261650/original

166 to about 180ish FSB.

KT400 VIA chipset does not have a PCI lock. That means with the /5 divider 166 / 5 is around 33 default.

190 FSB / 5 is max safe of 38.

200 / 5 is 40. If you have a VIA chipset instead of the PCI locked nForce2 chipset, that's hard drive scrambling territory so forget about above 200 FSB.

With good cooling, (don't be using retail heatsink) you may hit your mobo's max of 180 FSB with your PC2700 ram. Maybe 170something will be max, but see what passes 12 hours Prime95 torture test.

Of course, you'll need 1.8 volts Vcore so your mobo theoretical max of 180 FSB times 12 or 12.5 multiplier would be the max if you also increase the Vdimm voltage. Just do it gradually.

[rcillig]

ok how long do I need to run the torture test, I ran it for 12 hrs last nite and got no errors... or warnings.

12* 180 = 2.162... you think I can get more outa that or is that a good place to stay at.

as for temp.... it got in the in the high 40's Celcus that is.... during the test.

[c627627]

Excellent. You're in excellent shape with 12 hours Torture testing with no program errors. Get rid of the old crap from sig and put the new stuff in, similar to the way I have it in my sig, with all relevant info.

PC2700 and VIA chipset 180 FSB is about right on the safe side.

Now maybe you may up the multiplier. 12.5 x 180 would be close to the limit for the T-Bred B. Maybe try lowering FSB a bit first to test it with 12.5.

Good job!
