7N400Pro overclock attempt #2, need some help her

[carpenter]

I just went through this system again and got it back up and running. Apparently had a bad ide cable to the hard drives. I better give the system specs first. GA 7N400Pro, 2600XP w/333fsb, 2-512 Corsair C2LL slots 1 & 3, XP Pro. I have it running with a 13 multiplier, 1.700V, Normal Dimm OV, normal AGP OV, normal cpu ov, mem timings are 7 3 3 2. Reads as a 2700XP @ 2.17GHz. When I tried 13.5 @ stock 1.675V, it read as a 2800XP @ 2.25GHz, but would reboot every now and then. But I didn't increase any voltages. Any suggestions?

Slowly increase cpu voltage, and consider relaxing ram timings

I just increased the cpu voltage to 1.725 and it started rebooting. I keep hitting control F1 to get to the advanced settings and sometimes it works , sometimes not. I see you are running 11 for the first setting. Do you recommend this, or should I slowly work in that direction?

If you feel that you have good cooling and can monitor temps, continue to up voltge untill stable.

It seems that there is a new way to think about setting up ram, in particular with mb capable of 200fsb and beyond.
There are articles on this in the corsair, nforcers,and amdmb.com web sites.

The plain explination seems to be that something about the nforce2 chipset does not regard latencys in the conventional manner at this time and that higher fsb dictates looser timings.

I started out running my corsair 3200 xms c2 at 5.2.2.2, no prob. Ran that way for about a week and a half, also does 6.2.2.2.

Then I came across this post about ram timings. and have been running 11.2.2.2.5 every since.

If you do a sandra mem at what ever you normally run, and do one at 11.2.2.2.5 or 3, you will be surprised.

So If you think your ram can take the change, try it, it may also make you more stable, as a side note, others are reporting that this also increases their hd benchs, and 3dmark benches.

I have good cooling and even with trying some pretty wild timings my temps haven't gone above 43C. I'm wondering if it's the 2700 memory. Or maybe 2600XP's just don't like overclocking. So far I've tried everything you have suggested and about the best I can do and still run is 2.17GHz.

Im not familiar with the o/c abilities of the 2600, you should do a search at an overclockers database to see what people are getting with them.

If everything that you want to do with the system is stable, I would run it that way for now, let it burn in at that speed, and contine to research what more potential may be possible.

Good afternoon 3sixes, just checking this thread and thought I'd let you know that last night I let that box run as-is for a couple of hours to burn in as you suggested. Also installed a game and played in for a while to see how stable it would be and to give it a work out. Seems to be running fine @ 2.17GHz. I'm going to try and find some more info on this chip. Lot of people oc the 2500 because of bigger cache, but look at how far you and others take the 1700 and the 2600 has same cache. Seems like it could do better. We'll see. If you have a favorite oc data base to suggest, I'd appreciate it. And thanks for hanging in there with me on this, I really appreciate the help. Learning a lot of new stuff, probably making another oc addict.

Hello, carp

good to hear that youre running stable at those speeds, test as much as you can to be sure.

Try the following: overclockers.com has a overclockers database.

sysopt.com under their overclocking menu also has a data base.

Thanks, I'll check them out and see what they say. Got to get back to work so I'll let you know tonght how my experiments go.
