2100+ Tbred B (? -> yes!) at newegg for 92->101 dollars (1/14/03)

[MichaelD]

OK, I'm currently sitting at 2.23GHz. (12x185@1.675 volts.) It posted and ran SANDRA tests at 1.650 volts, but 3DM crashed to the DT. I'm so giddy, I don't know what to do next!! God, this NForce board is nice...no worries about AGP/PCI probs.

BTW, idle temps are 41C CPU/35C case. Using an AX-7/AS3. Also took of the Northbridge, cleaned off the pink pad and used AS3 there as well.

Numbers: (12x185)

SANDRA
CPU 6175/3087
MEM 2792/2636

3DM2001SE (GF4 4200/128mb no OC):
12036

UT2003 Benchmark (1024x768)
Flyby: 120
Botmatch: 72

Pretty decent, I'd say.

I really want to do some gaming on it before I muck w/it any further. I use this box to game on, not just run benchmarks.

Definitely feed it more juice You should be fine with that RAM by upping the FSB. I'm willing to bet you could run very nicely with Vcore at 1.85V, Vdimm at 2.7V, and settings of 12 x 200mhz = 2400mhz :Q

I'd go straight there with that RAM, unfortunately I only have PC2700 Samsung True, so only 187mhz FSB for me.

woohoo, can't wait until newegg gets more stock of this chip. I'm definately planning on feeding this CPU some fast ram... I hear the Kingston HyperX stuff is yummy. Figure the system will be primarily for gaming anyways, won't need a whole lot of ram so I'll go with just 256MB of the PC3500, woohoo!!! Then I'll be able to double it to 512 and run in 128bit mode.

I want to wait until the NF7-S rev2 board comes out though, so more waiting for me

 

[chizow]

Btw, those of you who are experiencing the 2ghz barrier for the first time, is it just me or does your computer feel SIGNIFICANTLY faster than any previous OC? Its been like running a completely different rig for me. I get a cheesy grin now anytime I run a game with max everything 4x AA and 8-tap AF at 1280x32....just awesome. Also, little things that would max out my CPU cycles don't phase this new chip, for instance, scrolling in IE no longer causes choppiness on my TV Tuner. There's other details I don't remember off hand, but its been the most extreme CPU upgrade I've made since going from a P3-500 (OC'd to 550) to a T-bird 1.4ghz OC'd to 1.6ghz.

I got my 2100 today, took most of the parts out of my case to get it ready for the new toys tonight when I get off work. I picked up the Chaintech 7NJL1 MB (I actully goofed, I thought I was getting one with the Soundstorm APU but oh well, its still a nice board) 2 256MB Geil PC3500 Ultra Plat dimms, the XP2100 b core, a copper shim and the TT Volcano 9 fan/heatsink combo.

I am not going for an outrageous overclock, although I'd like to hit 2.2 GHZ if possible. Its been a long time since I did any overclocking (celeron 300a was the last one), any suggestions on the best route to take here?

Thanks
Jason

Go straight to 1.7V and 166mhz FSB at the stock 13 multiplier. Do not pass go and do not collect $200

If you want 2.2ghz you just need to up the FSB 3mhz or so to 169mhz.

Up your Vdimm to 2.7V, set your RAM to sync or 100% and set to "aggressive" to start and tweak downwards from there. No reason you shouldn't be able to run 5-2-2-2 with that memory if it is half the advertised rating.

Actually, make sure your temps are nominal before doing all that, don't wanna be the bad guy if your heat sink isn't properly attached

OK. I didn't touch the DIMM voltage (cluck-cluck-cluck...maybe later). I got it to post at 2.4GHz (12x200) @ 1.85v, with the timings 2-3-4/CAS2.

I have seen the promised land. I took a screenie, JIC anyone doubts me.

It would surf and run Windoze apps fine, but 3DMark would make the box RESTART (just skip the desktop...straight back to BIOS)

I'm currently sitting at 2.23GHz @ 1.675 volts. I may need to up the voltage, as Prime95 gives me errors only about a minute into the torture test. What do you think?

*EDIT*
OK, I upped the voltage to 1.700 volts. I'm running the P95 torture test...it's on the 10th test now w/no errors. I'll let it run awhile til I feel like gaming, then I'll let it run overnight.

I would be happy w/a 2.2GHz chip for $105, you know?

*EDITX2*
I keep getting the "round off" error. What does this mean, besides my OC sucks? :|

Try 12.5 * 192 Exactly 2.4ghz, and this way your ram might not be limiting you anymore.

 

[mechBgon]

What chizow said, add a little more voltage to the memory. 2.7V isn't going to hurt it.

 

[bunnyfubbles]

The guys that do extreme stuff run their memory far past 3v, and it seems to take it quite well. Helps to "burn" stuff in.

Oh, and Chizow, I don't think its the 2GHz barrier as much as it is the high FSB speeds (atlhough I'm sure its both). Some guy broke 21000+ 3DMarks with a 2.69GHz Athlon but it was mostly his high FSB on an nForce2 that made the difference.

 

[MichaelD]

I don't know what is limiting my OC, but I don't like getting errors in P95. Any errors means your OC is unsuccessful! I'm at 185MHz now...I upped the core to 1.700v...still getting errors. All other benchmarks run fine, though.

 

[bbrener]

Slightly off topic I know but interested to know what cooler you guys are using for this oc. I may overclock slightly but not much with a 2100+ and want a fan/heatsink that doesnt sound like a jet engine.
Any recommendations? I like the new Vantec VA4-C7040 but seems as if it does not recognized by the Bios so there are alyways alarms. I will be using an ABIT NF7-S and Corsair PC3200 CL2.

Thanks

To the CPU, I assume? The RAM is rated for 200MHz at stock voltage (I assume) BTW, the default DIMM voltage on the 8RDA+ isn't 2.5v, but 2.6v. they want you to go for it, apparently.

Both!!! 1.85VCore, 2.7Vdimm.

Cripes, I don't want to fry thing the first day! What are you running, Chiz? Mult/mem/voltages, please.

 

[chizow]

Hehe you won't fry it, worse thing that happens = no boot into Windoze.

I'm running pretty much the same set-up as the first day I got it..haven't really tweaked anymore b/c I'm waiting for you suckaz to get your chips and test em

Anyways, 1.85 Vcore, 2.7Vdimm, 13 x 187 (I think it actually goes to 186 though), memory "100%/Synced", timings 7-3-3 cas 2.5, AGP locked at 66mhz.... System is not 100% rock solid stable, it gets through 3-6 hours of Prime95 torture, but thats fine for what I do with my rig. I can loop 3dmark all day and all night though I'm considering getting an SLK-800 as I still don't want to deal with water right now.....hmmm....fish tank in my window would be pretty cool......

Chiz

 

[MichaelD]

LOL! "Fish tank in the window". I like it.

I appreciate your honesty in saying "it's not 100% stable." I hate it when people say "yeah I'm running 13 x 225 at stock voltages and it's rock stable."

Such liars, some people.

But you are the man. Those timings....you have PC2700, correct? I have suggested timings for my PC3200 from The Epox God, AKA, Insane3D and they are really high (low) as in TRas4, TRcd2, TRp2, CAS 2. That's what I'm running right now at 185MHz. When I go higher, I up the core voltage...but I can't tell if it's the CPU or the memory holding me back...I am pretty sure it's the CPU.

Been running P95 for about 15 minutes now and it's good to go. I guess it was the voltage after all. Thanks, bunnyfubbles.

BAH! I cannot resist...must go higher!

 

[bunnyfubbles]

np,

Just been reading about nForce2 overclocking senarios, some of these guys are willing to put their $250+ Athlon XP chips at 2v no sorta makes me think that 1.85 is nothing These guys mod their boards to put soo much voltage on their chips, it is near insane.

 

[MichaelD]

Damn, 2.2GHz is FAST! I'm HALFWAY thru the P95 torture test and it's only been running about 30 minutes! :Q BTW, I just ran the 3DMArk BMark while P95 was running. NO errors. Apparently, 1.75 volts is the "sweet spot" for 2.2GHz for me. I will shoot for more...gradually. (cluckcluckcluck)

 

[Dug]

Is it possible to o/c these to around 2.4 - 2.5 with memory only being rated at 2100 (Good up to about 150fsb)? Using an 8rda+.

Not familiar with AMD only Intel.

 

[bunnyfubbles]

I don't think so as I don't think you'll have access to the higher multipliers you will need with out a mod. Trust me on this one, it is worth it to invest in some 400+MHz ram as the high FBS is where the brunt of the speed is at. High FSB = win.

 

[Dug]

I thought with the Nforce2 boards that there was a lock available so your memory was independent of the fsb?

 

[BigJ]

You sir are correct. You can run the FSB independently of the memory, but thats kind of a weird way of doing things. I know in my A7N8X Deluxe you can it at a few different settings. Lemme check my manual and I'll get back to ya.

EDIT: Checked it, and you can run it at 50%, 60%, 66%, 75%, 80%, or 83%
