Need a little help ocing a 2500+ using an old video card

[idea]

I have this current setup:

Barton 2500+
Abit NF7-S
Riva TNT2 32mb SDRAM
Corsair TwinX-LL 512mb PC3200

I have set the vcore to 1.8v and 2.9v for ram. i'm going for 200fsb x 11 (3200+) i have tried the following ram timings.

11-2-2-2
11-3-3-2

Neither are stable using prime95, i'm wondering if I'm going in the right direction. I'm also concerned about my old video card which i'm not really interested in upgrading because i don't do any gaming, and it is fine for me. If you have any tips, please let me know.

If you have new 3200LL modules then RAS to CAS delay will cause you problems if set anything else then 3 (like 6 3 2 2 =OK; 6 2 2 2= problems) you can even do 5 3 2 2 but not 5 2 2 2 .

you don't need that much of Vmem since you're still within specs of your memory (here i run the same memory at 217mhz with 2.7V and a multi of x11 @ default Vc but i have an old 2500 week 19) try lowering your multi and see at what x you get stable then bump the fsb just to see...

For the motherboard (and other stuff), i'll leave tweaking advices for ppl with more experience then me with Abit NF7-S.

Idea, did you lock the pci to 33mhz, and the agp to 66mhz? If you have, try moving the ram that's in slot 3 to slot 2, so your motherboard will be running in single-channel mode. It really doesn't benefit the Athlons much at all, 1-3%, depending on the application. If you can get just a couple more mhz of fsb, you will more than make up for the difference. Plus, are you using Prime95 version 2.21 (the stable one), or 2.37 (the one we've all had problems with!)?

I'm running prime95 22.12.1

6 3 2 2 = stable for 30 mins
5 3 2 2 = stable for 5 mins

I cannot lower my multi because it is factory locked

I did not lock any PCI or AGP, should I do that and then try the ram trick? I have 1 stick in slots 1 and 2 at the moment.

 

[idea]

11 3 2 2 = stable for 30 mins
8 3 2 2 = stable for 1 hour and still running. this one seems most promising. if it does fail, should i try 8 3 3 2?

I took your advice and put the Vmem back to almost stock to 2.7 (stock is 2.6)
Vcore is at 1.8v though and making my cpu run at 50c under full load but it seems okay.

The real problem is how confused I am with what these numbers mean. I know what the last number is, that's about it. What do I gain by changing their values? Why do some people say to use 11-2-2-2 then some people say 6-2-2-2 or 8-2-2-2. Why not 20-2-2-2 or 2-2-2-2
