XP2100 overclocking - results and questions.......

[caliguy]

This has been my first pc building and overclocking experience and it I would do it again.
So far I have overclocked my week 49 XP2100 (on an Asus A7N8X Dlx board) to 2210MHz (170x13 @ 1.80v). I ran prime95 torture test for around 18hrs and no probems, I have also run 3DMark2001 and 2003 without issues.

Click to see bios image:
Click to see WCPUID image:

I would like to get at least over 2400MHz.

Now for the question:

1. Looking at my bios pic, have I done everything right so far? Is there anything I should change if I was going to leave it at this speed?
2. What should I change to overclock higher? I tried 175 fsb with 1.825v and got "error" result in prime.

Again, I am new and still not very familiar with overclocking, any help is appreciated.

Thank you all,
Cali

you have no guarantee of getting over 2400

2240 isn't bad...

just try upping your FSB now slowly.... until you hit a wall... 1.8V is about as high as i would go...

i'm running 1.775V and it's doing just fine..

i've up the vcore before and got it over 2400 easily... but no matter what voltage i use... prime always fails...

be happy with that overclock

your memory timings need to be changed first off...set them to something like 6, 3, 3, 2.5

second....lower the multiplier and up the fsb till you get just right..i can hit 205 stable @ 11x

right now im at 2.3GHz with 11.5 x 200fsb

also something non OC related....change your AGP aperture to 128 plz

its at 7 3 3 2.5....

what does cpu interface option yield?

...ot:
what does graphics aperature size do anyways ??

...eddit

memory timings = aggressive at 7 3 3 2.5??


you locked agp right/

 

[Namtaru]

6,3,3,2.5 has given me better results than 7,3,3,2.5

the CPU interface option i have yet to fully work out, mine is set at Optimal right now though

AGP Aperature size..it's hard for me to explain...if you search google it will help... but basically running a 128MB card and having it set at 128 will give you the best all around results

and no i don't need to lock my agp, i SET it at 66MHz

other voltages are
CPU Vcore: 1.85v
AGP: 1.6v
DIMM: 2.9v

i also have the pheonix BIOS and would post a pic but don't have hosting

actually it's best to set it to at least 64MB, but usually ~1/4 of your system memory. He should set his AGP aperture to 256MB.

I have a 64MB GF4 Ti4200 and for some reason, I get very stuttery performance in UT 2k3, UT, etc when I set an AGP aperture size of 128MB; 256MB clears this up completely (I have 512MB of RAM).

 

[EdipisReks]

a vcore of 1.85 and an agp aperture size of half your system ram is what i would run at.

 

[alchemize]

I have a 128MB card, and 512MB of ram. If my aperature is set to 128, it won't post A78NX deluxe

Thank you for all the replies.

"your memory timings need to be changed first off...set them to something like 6, 3, 3, 2.5"

1. I have set my ram to 5-2-2-2 (advice from Overclockers.com forum), would 6-3-3-2.5 be better? How do I check which ram settings are best, everything seems to be fine at these settings?

"actually it's best to set it to at least 64MB, but usually ~1/4 of your system memory. He should set his AGP aperture to 256MB"
"a vcore of 1.85 and an agp aperture size of half your system ram is what i would run at"

2. Ok, i am a little confused now. I tried 128,256 and 512 and all seemed to work fine, again, I am not sure how I should test which settings are best. I tried 3DMark2001 and got a little better score @512 setting. I have 2x512 Corsair XMS DDR400 ram.

Thanx,
Cali

5-2-2-2 is faster and therefore better than 6-3-3-2.5 To see the difference in settings get SiSoft Sandra or a similar program that will benchmark the memory subsystem.

This tells how much system RAM is allowed to be used for texturing (overflow that won't fit in the video cards RAM). The old rule of thumb was to set it to 1/4 or 1/2 of system RAM, but system RAM is alot slower than video RAM, the setting is basically irrelevant in 64-128M video cards. I'd just leave it at whatever your BIOS default is.

I think you hit the wall with your processor. Your ram timming are mild for the brand/type you have. And if increasing CPU core voltage yeilds nothing more, i'd say that's it, though I am surprised, is that a Palamino and not a T-bred chip? That would explain it all.

It is a tbred chip DUT3C 0249. I was playing with different settings before I flashed the latest bios on my board, but these overclock settings are really my first ones that i have kept for more than 5 minutes.
I have been running 2210MHz (170*13@1.80v) for 3 days now and ran Prime95 for over 18hrs to burn in. I would like to think I can go higher, who knows maybe, maybe not.

Thanx to all the responses I am learning something more about overclocking each time.

Um, are you stoned? Palomino at 2.21 Ghz with some aircooling, I don't think so! 2.2 GHz is a very nice o/c (~2800+ speed is nothing to scoff at).

 

[caliguy]

Woohoooo....................

Got it up to 2280.16MHz using 175x13@1.85v.
Prime95 torture test is running fine for an hour now and I ran 3DMark2001 while running torture test and everything was fine.

From what I understand I should now run prime95 torture test for over 12hrs to burn in again and then try upping again, correct??

Actually no, it's been at least 10yrs since my last stoning and does it not say watercooled in his specs?
And, I never said his 2.2gig or whatever was something to scoff at.
