View Full Version : 1.6A owners: what's the highest STABLE overclock you guys have, and at what voltage?

i was running 2.48 @ 1.8v and it was pretty stable, the stability was also based on the ram preformance which i lowered to the 300 stock setting vs. 333.

I know that I may be somewhat out of the loop... but how do I distinguish a 1.6A from another, less overclockable chip?
I take it that it's the 1.6A, specifically, that is the one to look for, no?
I've been happy with my P3 600E (at 800 rock-solid, of course)... but the temptation of an 800MHz overclock with similar potential stability... just might be too great for me to pass up.

I'm trying to oc my 1.6a but I'm having problems with my hd. My maxtor didnt like switching over from the msi845ultra to the 645ultra333. I should have reformated but I'm hoping to fix it w/out reformating.
BTW the cpu came full retail but i still had the tt volcano 7+ from the 1.7 and thats what im using.
Oh and the 1.60a is the northwood version. Socket 478. 400mhz sys bus. 512-KB L2 Advanced Transfer Cache .13 micron. Product code:BX80532PC1600DSL668.
ps:can you guys also list your hardware and what software your using(os etc). i'm shooting for 2.4 stable, but since every chip/system is different, who knows........

using the old ibm hd now. got cpu running at 2.2 and ran one test in 3dmark. I'm going to see how high i can get and than fine tune. Score on 3dmark 8000+.

btw the voltage is at 1.600. i'm using a tt volcano 7+ (on low-mid settings if it helps).
funny thing happened when i got to 133 fsb my system switched my ratio from 4/5? to 1/1. The ram mhz went from 352mhz(?) to 266mhz and than started going up at a 1/1 ratio.
The ddr2700c2 seemed to run well at 352mhz and i lost a lot of performance when it dropped down. Right now just going for speed. Later scores and than more tuning to run everyday and get the marks your asking for.

does anyone know anyway to get more voltage from a msi 645ultra mobo to the cpu. i got it up to [email protected]
i could boot up and go into windows and open up 3d mark etc, but couldnt run it. i noticed your running 1.7+ and i need more than 1.6. she's not getting above 45 celsius(at low setting) and i'm pretty sure a little more juice will get me over. any thoughts would be appreciated.

Very cool. My cousin is an engineer im sure he has the stuff needed to make the conversion. i'm thinking to use the pen, all that twisting leaves too much room for me to mess up.

as CF was saying that is one baaaddd cpu. it took me a few hours of testing and tweaking to get mine to run and test at 2.3+ghz. i am currently running it at 2.25 and having no problems. once i get the voltage i plan on running it right around 2.4ghz.
i've read of people getting 2.57+ghz air cooled. the extreme dry icing guys are going well over 3ghz, but i don't see myself doing anything that can't run 24/7.
i looked for the bare cpu and no go. i wonder if all northwoods come full retail. now i have an extra cooler and my "pent inside" sticker :P. might do some testing to see how loud and what the heat difference between my two coolers are.
