vcore and stability.

RF · March 17th, 2003

As some of you may know I recently purchased a new box.

Mobo: Asus A7N8X DLX nFORCE2
CPU: T-Bred Athlon XP2100+ 1.7ghz default.
RAM: 512mb OCZ PC2700 (333mhz) /w Heat spreaders.
PSU: Enermax 350w @ 1.6vcore.

Now. I was able to overclock the 2100 up to 2079mhz (2.08ghz) (166fsb x 12.5m) (XP2600+). Without touching the vcore @ 1.6 and remains at a constant 36 degs celcius (Thats awesome cause my old 733 ran at 41 celcius). Now, when I push the multiplier up to 13.0 (fsb still at 166) I got 2158mhz (2.2ghz). This is when winXP /w sp1 would lock up after a while. So my question is:

If I push my vcore up to 1.7~ will I be able to run 2.2ghz without lockups? Or should I be happy with 2.08ghz?

EDIT: www.overclockers.com reports that every1 with a tbred xp2100 had their vcore @ 1.7...

I'd say 2.08Ghz is good enough Reich! You're almost right on with the PR Rating huh?

Hanamichi · March 17th, 2003

Pushing the vcore should increase stability. Unless youre planning on keeping that CPU for like 5 years, I say go ahead. Doing so generally shortens a cpu's life and generates more heat but it shouldnt be a problem with adequate cooling. Just dont look for me if anything happens.

If you dont need all the extra power however, I say dont overclock.

JAZ · March 17th, 2003

All those 2100+'s are b version chips, you have bought good memory so dont bother upping the multi use the fsb to increase your overall speed.
Start by lowering the multi and then find the fsb limit of your cpu/mem, increase the v-core but keep an eye on the extra heat the increased volts produce, if the temps at higher v-core are ok then leave it higher if it gives you more stability.
Once you find the fsb limit reduce it a few mhz then start upping the multi to find the maximum speed you can run.
Mess about with the memorys v-core as well and use agressive mem timings but bear in mind this will limit your fsb a bit but faster timings at a lower speed are generaly better than lower timings at a faster fsb.

Shud i overclock my P4 2.4ghz? haven tried any overclock stuff yet...2.4 shudnt be any prob rite now rite?

Hanamichi · March 17th, 2003

Actually anything beyond 2GHz doesnt help much at the moment. I would think that the main target of overclocking when you have a fast CPU is pushing the FSB (hence increasing bandwith).

Player-X · March 17th, 2003

I wonder how fast can a Barton go when overclocked

Chinoz · March 19th, 2003

Hey Han, you missed bragging rights. But extra b/width won't help much unless you're saying that you have dual channel ddr400.

Hanamichi · March 19th, 2003

Well pushing FSB means pushing the RAMs as well.

If you like to brag, I guess...

RF · March 21st, 2003

Thanks guys! Ive been away with life and havnt been able to access ngemu for a while. The great thing about this asus board is it locks every other bus, be it agp, pci and memory, so you dont have to worrie about all the other stuff. Im happy at 2.08ghz right now, I dont need that extra 100+ mhz.

Thanks

Not neccessarily, some boards lock all the other buses like Reich said. Definately gotta get a board like that next time for sure!

Raqia · March 21st, 2003

After a little hardcore stress testing, I advise against FSB overclocking unless you have a board that locks other buses if you want a rock-solid system. But if you're just gonna play a few games, I'd recommend pushing everything until you start getting artifacts or can't complete 3dmark.

On the contrary, FSB oc'ing is much safer then changing your multiplier. Changing your fsb changes only your cpu speed, nothing else.

Err notice how he said

It might only change your cpu speed only as you have a locked pci, but not everyone has locked buses on there board, me included.

Heh, when I posted I was short on time

sorry

Thats cool

Nice overclock you got there btw

Aleksei (St) · March 22nd, 2003

i think that you shoul stay at the level you are 2600+ very good form a 2100+ proc

This Alpha heatsink I have on there with the arctic silver is a great combo.

Hanamichi · March 22nd, 2003

That's true Esturk, though I (and some people I know around)wouldnt lock the memory bus. I mainly overclock to increase memory speed anyway.
PCI and AGP locking is good though(my board does).
