WOW! Timings helps a lot!

My board, a 1.2V of the Nf7-s isnīt really an overclocker as it maxes out at around 205 Fsb.

Itīs chipset limited at available voltages really. I have been running a pair of cheap Twinmos Pc 3700 at 5,3,3, cl2 Timings all the time and havenīt really bothered to tweak more.

After some reading on different forums, changing tras to a HIGHER number can help with bandwidth and stability.

I changed it to 11 so the timings now are 11,3,2,cl2. (changed the 3:rd as well)

This is over 500/500 more bandwidth than at 5,3,3,cl2.
Not a super high bandwith but at 205 it isnīt that bad either.

Bad image but it is 3124/2966

Since you changed the timings, have you been able to oc to a higher fsb speed? I seem to have read about this over at o/c.com forums too, about getting better memory benches after setting tras to a higher number.

Not really since it is my board that is the limit here. 205-206 is known to be the limit on the 1.2 version of Abit. The 2.0 is going strong at 240 fsb though.

And that's rock solid stable there Mack???
I tried changing the tras in my timings but didnt get the same jump in Sandra score as you did. In fact, I got just a very small increase. Meh, Ill stick with the 4-2-2 cl2 207fsb for the time being.

Yup, dead stable. But it is a single 256 mb of Twinmos/winbond ch5 that needs over 3.2 volts at timings 11,2,2,2. I cant wait to test my 2 Twinmos 3700 sticks. The sucky new OCZ golden blah blah PC3500 wont do anywhere near that.

Be aware that ANY 512 stick is worse in at overclocking on Nforce2 boards. It just doesnt have the juice enough for dualbank configuration. Stay away from the Twin deals of ANY 512 sticks on Nforce2. We are checking if more caps on the memorycontroller can help though.

Holy %6@Ģ!!!!

Is that your new pre-modded Ver.2???!!

What CPU has it got in it?? The 1700+ or the 2100+ ??

OMFG... that's a serious mofo of an overclock!

WELL DONE MACK!!!

Yes!

It has a modded 2100 as of now, but as soon as i can,i will try that 1700. If its not working, i have a 2100 that can do 2.6 gigs at best. I WANT 250 though. Im not giving up until i have that. Im even willing to pelt the northbridge if i have to.

And of course, credit is due where it should be, without Lasse this wouldnt be possible. That guy is a genious.

248 fsb, but relaxed timings:

Seems like the Winbond is at their end now. Stable though.

Keep it coming Thraxters!

What sticks have you got? 256 mb sticks is waaaay better. But you probably knew that already.

hey thrax, try 2/2/2/9 see if it helps, i tried different settings, 9 on tRAS was the best for me.

2 x 256 of Corsair XMS3200c2.

I want a gig, but it looks like I'll have to settle for 768mb of memory if I want to keep overclocking at a reasonably high level.

Same here. If someone could create good 512 sticks that is singlesided iīll be happy. I havent seen ANY 512 sticks that does serious overclocking on a NF2 board. Not in dual.

Guys, I'm seriously trying to wait until the Athlon64 comes out before I upgrade, and then you have to throw benchmarks like that in my face. My credit card is starting to burn a hole in my pocket.

And here's why:

Hmm, I've got two HyperX 3500 at 256MBs each, and I cant get above a FSB of 200 without stability issues.

Think it could just be increasing the tRAS to fix that? I should'nt have to increase them, as the mem is under clocked as far as it's concerned.

Thats weird,

That is supposed to be one of the best sticks for this board and i have seen millions of peeps running at over 220 fsb easily on that board on air even. Does cas 2,5 help? If it does, then try one stick at a time to see if one is worse then the other. Use maximum chipset and memory volts. Drop the multi to 8 or 9 during fsb testing.

It COULD be my cooler. At 2100 Ghz, the CPU temp hits a high of 60 C under load (F@H). This could be what causes the lockups, but I would think the PCU could hit 70 C before becoming unstable.

Lets test them memory first. Drop the cpu speed and voltage to the core and use a lower multi like 8 or 9. Then we know its not the cpu or cooling that stops you.

I'm with Garg's boat

Int - 1907MB/s
Float - 1847MB/s

A7N266-C with plain nForce with an 1800+ (or what I THOUGHT was an 1800+.. it came home running at 1.15ghz..

One stick of 512mb PNY PC2700 (Yeah I know.. but I bought it when I didn't care for OC'ing. I also didn't know my CPU was at 1.15ghz ).

Templar,

Your cpu is just fine but your motherboard needs to be setup properly.

Either in the bios or on the motherboard itself, there is a jumper (switch) that decides whether you run your memory bus at 100 or 133 mhz. My guess is that just by the flick of a switch, theoretically you will have a 33% faster pc.

Depending if you have the jumperfree setting enabled or not, you can change the CPU-Dram frequency setting. I think it is set at 100:100 now when it should be at 133:133. Your cpuīs multi is 11,5 and take that times 133 and you get that 1800īs REAL speed. After you have set that jumper, you probably need to change the fsb manually to 133 as well. When you have done that and you have your things running as they should do, weīll start overclocking.

This is from your user guide:

I went from 211 to 216 and my scores lost 200mb on int and 400mb on float. At 216 I'm at 2950/2560, instead of 3100/2900 at 211MHz. WTF?

//EDIT: I had to take it all the way up to 218MHz on 2/2/2/(6/9/11) to get 3GB/s of memory bandwidth. What went wrong?

I've benched and benched over and over, and it still pulls in 2989/2549 to 3020/2610.

2/2/2/9, 2.8v, 218MHz. I have my multiplier way down in the 7x range to test the FSB...That shouldn't matter, right?

It shouldnt, but i have noticed that theese stinky Nforce 2 chipsets are very strange. You can in many cases get MUCH more fsb with a 9.5 multi instead of 11 even if your cpu can take it.
Different scores on different boards.

Can you test 11,3,3,2 or 11,2,2,2 and see? Should work, my BH5 does that at that fsb and onboard voltage.

Have you modded your cpu to 166?
