Hey everyone,

Well first again I'm a newbie so bear with me. As yet I have not run prime 95 I intended to do that but I wanted to check with experenced folks here first to see if I have everything optimized before running prime95. All I can tell you is the cpu status software I downloaded from here tells me my real clock speed is 2351mhz. I think the software is WPU51 or something like that so I guess if the application is trusted it should be the real speed?. When I get home tonight I'll make a screen capture and post it to this thread.

It seems stable with my current settings I installed UT2003 and it ran flawlessly. As far as date codes and the like I'll try to find the invoice I got from new egg and see if it is captured there somewhere. I'd check the chip itself but it was a real hastle to get the darn volcano 7+ locked down onto the chip. I would guess everytime you pull it off and on you run the risk of damaging the processor no? Accidental chips to it ect...

So correct me if I'm wrong but people suggest I do the following:

1) Readjust my vdim setting to 2.77V

2) Readjust my vcore from 1.68V to what 170V-177V?

3) Set multiplier to 11?

4) Set FSB to 200

5) Run prime95 for how long? hours? days?

Again I asked this question but didn't really get a good answer so I'll try again how hot is too hot for this processor?
As of now I'm runing between 34c-35c pretty consistantly in all conditions granted I'm not sure how that would change under
the load of this prime95 software.

So thanks for everyones help and expertise it is very much appreciated....

I wouldnt worry about pulling the HS off just to check what week chip u have.

Definately try 11 xs 195 1st, run prime 95 for 3-6 hours (this is the TRUE test of how stable it is, not running ut2k3 🙂

If all goes well, then bump the fsb up to 200. If that is stable then bump the clock up to 11.5 🙂

Nice and easy, just take steps, check for stability. When stable, bump it up slowly again until it is unstable, then back it down a tiny bit.
Make sure to run your RAM in synch mode with the FSB.
 
Hey Mboy,

Thanks for your advise I will do as you suggest tonight the only thing I don't know how to do is:

How do I sync the ram to the FSB?

Is there a jumper to seting or a soft setting somewhere in the bios screen to do this?

I only have I memory stick of DDR400 @ 512Megs

Again what is too hot for the chip to be running at ie is 50c too much 80c?

Thanks,
-ES

PS I'll post the results tonight with screen captures


 
it is in the bios. Read the manual, it will tell you how to adjust everything.
I would say 50c is on the high side for an xp2100 on on 8rda+ for sure.
Mine is 39c under full load to give you an example.

50c is perfectly fine.
 
Hey mboy,

Thanks ok I'll read the manual when I get home and sync the ram to the FSB. Well if currently running at 34-35c at idle @2.351mhz so
I very well may be ok then I suspect temps will climb when I increase the Vcore to 1.77V . Ok will do the experiment tonight and run prime 95 for say 4 hours and see how we do again you help is appreciated... I'll post result either late tonight or sometime tomorrow

once you've established that the chip has some modicum of stability, run prime 95 over night. and for the sake of all that is good in the world take that heatsink off and tell us what the week is!!! 😀 just make sure you don't break it putting the sink back on.
 
Hey guys,

Well don't get too excited yet with the date code stuff for the chip for all I know the thing will bomb out the gate once I launch prime 95 on it and need to scale back I guess well see soon stay tuned 😀

-ES
 
c'mon, c'mon, c'mon, stable, stable, stable, week, week, week, credit card, credit card, credit card, buy buy buy!!
 
and did you ever say if this was a 1700+ or 2100+ or other model cpu?

btw, for a true test of stability run Prime 95 for at least 24 hours. i've had errors @ 18 hours of running! honest!! 😀
 
and 34C is cool as a cucumber! 😉

my full load temp is about 20 degrees above ambient so between 38 & 41 depending on room temperature these days.

of course i'm only @ 2200 (200 * 11) 😀

Nope, he didn't. We all know it's a 2100+ (1700+ at 2.35 GHz @ 1.68V, puh-lease!) but he should specify which chip he has just to make it clearer!

Edit: of course, it could be a 2400+, 2600+ or 2800+ ... evilsponge - let us know which model your CPU is! 😉
 
Hello all,

Ok well first to clear up what processor I have here is all the info I have on it:

AMD Athlon XP 2100+/266 FSB Thoroughbred Processor CPU 2100+/ 1.73GHz -OEM, AXDA2100DUT3C
The Ultimate Digital Media Experience in an x86 Platform.Tailored for Microsoft® Windows® XP. Featuring QuantiSpeed Architecture for Rapid Execution of Applications. Tomorrow?s Technology Today.The Power of a Reliable Partner.
Specifications:
CPU: 1.73 GHz
Type: 2100 XP Thoroughbred (revision B)
Cache: 256K
BUS: 266MHz
Micron: .13
Socket A (PGA) OEM (Processor Only) Model#: AXDA2100DUT/3C Text

Also I read the manual nowhere can I find how I am supposed to sync the ram to the FSB anyone else know?

Will add link to pic for currrent settings:

Here is a screen capture of this config output:

Screen Shot of current CPU performance
 
damn.....now i really want that chip
week please😀
i also have a V7+
i know it's quite hard to install it, but inquiring minds need to know😀

and pertaining to your question, try setting the CPU:RAM ratio to 1:1
then your ram will run in sync with the CPU
 
Hey everyone,

Ok I got the story now: when I run an FSB of 200 I get the full 400DDR anything less and I am running
333DDR so it looks like my current config cannot accept a 200 FSB it's fine at FSB of 195 and a DDR of 333 the result is 2.351mhz. my system goes unstable at 200 FSB and 400DDR any thoughts as to why?

So I am now running in the following config:

AMD Athlon XP 2001+ OC to 2351Mhz

FSB: 195
Multi: 12
Mem: 5,2,2,2
Vcore: 1.77V
VDimm: 2.77V
CPU Temp: 37c-38c
Ram synced to FSB
Graphics set to 128M

Could it be because I 'm running only 1 stick of Corsair XMS DDR400 PC3200?
Another question I can get the same speed if I drop my FSB to 180 and change my multiplier to 13 so which case would be better for my setup?

Well thanks for everybodys help and advise I'm a little dissapointed I can't runn @ 400DDR and the 200 FSB oh well I will now run prime95 and see how we do

if ram is sync'd to fsb, you're not running ddr333, you're running ddr390 (double the fsb (an idea: don't get so hung up on ddrXXX or ddrYYY. just run it and let others worry about the "official" name for it)) which is pretty darn good still!! you could try loosening the memory timings a little. 5222 is quite agressive. if you're don't have the Low Latency Corsair, they only rate it to 6332. the low latency stuff is rated to 5222

you could rule out the memory as a culprit by lowering the ram sync % to like 5/6 or thereabouts and putting the fsb @ 200. you'll end up @ ddr333. if things still are not working it's either the chipset or cpu.
 
I see your multiplier is still set @ 12, did u drop it to 11 when u tried to hit 200fsb?
You are getting yourself too wrapped in up the 2.3GHZ nonsense. Your setup will def. be faster runnning your FSB at 200 with the mutli @ 10.5, then 180 x13.
bump your vdimm to 2.9, drop the multi to 11 or 10.5 if you have to and keep the FSB at 200. FSB is where you pick up speed. Multiplier overclocking is sort of like fools gold.

i wouldn't exactly call it fools gold. you know a clock speed increase w/o fsb increase (multiplier o/c) will get you a performance boost 99% of the time.

the trade-off between higher fsb & lower clock speed to provide similar to better performance takes more experimentation, but you are right in that the best o/c clock for clock is the one with the highest FSB.

with PCI & AGP locks it doesn't provide the overall system boost that FSB o/c with a PCI divisor brought, but the much higher range of FSB speeds attainable more than makes up for that, imho. 😀

 
Hey guys,

Thanks I have a much better understanding of what is considered the most imnportant
parameters for OCing. I tried many combos of FSB and multiplers my system just won't
run stable with a FSB of 200 🙁. Even when I drop the multiplier down to 10 or 9 it still
reboots?. Right now I'm running stable @ 11 multi and 190 FSB will run prime 95 and see
if it stays that way if so then I will increase the multi and retest. Can you guys think of reasons why I may not be able to reach 200 FSB? Someone mentioned I may not have enough VDD?

Thanks,
-ES
 
Yeah, it has been hit or miss with 20fsb, I must be one of the lucky ones.
If stable @ 11x190, try upping it to 11.5x190 and if stable there, be very happy as u got yourself a VERY nice overclock 🙂
 
Thanks mboy you and the rest of the forum have been very helpful especially since I'm new at this whole oc thing. Yeah I'd have to say you have a nice combo there! When it did run at 200 FSB * 11 it was damn fast. Oh well 190 *11 is still way better than my first attempt of FSB 166*13 😀. I will run prime95 for 4 -hours and see how she does.

Thanks everybody!

Hey everyone,

Ran prime95 for 10 hours at the follwing settings:

Multi: 11
FSB: 190
Mem: 5,2,2,2
Vcore: unloaded 1.74V
Vcore loaded: 1.77V
CPU temp unloaded: 34C
CPU temp loaded: 39C-40C
Gainward GeForce4 128M oced to: 290/540

CPU Speed: 2051 Mhz

Prime95: 0 errors

Moving to 11.5 multi @ 2194.39 Mhz
Will rerun prime95 so far so good all in all I;m pretty happy 😀
