Editted: New post a few posts down


I decided to get some parts put together a new system for a little OCing fun, & so far it seems okay...much more testing is needed still, of course.

New parts -
Mobo: MSI K8N Neo2 Platinum
RAM: Corsair VS Dual Channel 4x512 MB = 2048 MB
CPU: A64 3200+ Venice
Case: Thermaltake Soprano
PSU: OCZ Modstream 520W

Parts from previous rig -
HDD: Raptor 74 GB
Video: BFG 6800GT
Sound: Audigy 2 ZS

CPU stepping:
ADA3200DAA4BP
LBBLE 0516EPMW (week 16)
Z639026D50102

Sorry about the big screenie.


So far it seems like the Neo2 is undervolting a little as i have it set at 1.4V, yet it is always below.
I also only have run Prime for a couple hours, so stability is still somewhat in question.
The most important test of stability to me is being able to run UT2k4 for hours on end...so that remains to be seen also 😉

I am kinda curious what type of Prime testing you guys recommend.

I still have to get my Zalman 7000 replaced, since it's been acting weird since i got it (doesn't turn on without a litte help sometimes :Q), so hopefully over the weekend i'll be able to crank things up a little.

RAM is @ 133 divider which about 250/166 according to CPU-Z. 2.5-3-3-7 currently.
HTT @ 4x250


Anyway...i'll have more fun later...time for me to hit the sack 🙂
 
dont stop at 2.5 you may be able to hit around 2.8!

edit: looks like you havent touched the voltage, and its also slightly undervolting. You might get a bit more headroom if you up to 1.55ish
 
Yeah i'm hoping i've got a ways to go 😉

Gotta sleep now though 🙂

Edit: Holy shiat! You are running your Corsair at 1.5 :Q?
 
i don't think you can runyour ram at 1.5 volts... more like 2.5? i'm pretty sure! 🙂

as for prime testing... use the small fft's, not the large ones or blend...

that chip looks real nice... i think 2.7 to 2.8 is VERY possible
 
No i meant CAS 1.5.

He has the same VS Corsair as i do...i guess once i hit my CPU's ceiling i'll have to see if i can tighted my timings up at all.
 
I'm getting kinda annoyed with my Neo2 now.

See this?

That shows my CPU voltage is about 1.46...yet in the bios i have it set for 1.55 + 3.3%

I am not certain, but i am assuming that the option to set the additional percentages bumps it up above 1.55V normally?
I'd appreciate if Duvie or bjc112 could confirm this.

The thing is, i am wondering how accurate CPU-Z & Core Center are vs. what i set in the bios.

Should i try to get it higher since the programs say it's way low, or could they be reporting it wrong?

You definitely need the + VID %..

Try 1.450 + 8.3% to end you up around 1.5v

1.475 + 8.3% should get you @ 1.55v

Don't even mess with 1.6v 😛

CoreCenter seems pretty accurate IMO, typically right on with CPU-Z as well..



Keep us posted.
 
Oh, okay...what does the + VID% do anyway?

I don't understand why just setting the regular voltage doesn't work...never had a mobo with that +VID% thing before.

I have LDT @ 3x when my HTT is over 250 (i know to keep LDT x HTT below 1000)

RAM is @ 2.7V

I am using the 133 divider right now. Timings are 2.5-3-3-8
2T of course


Just now i tried 1.45V + 8.3% (comes out about 1.55V like you said) for 10*270, & i cannot run Prime or 3DMark w/o problems...🙁
Do i need to loosen RAM timings even more? Higher RAM voltage?

I got to 2.5 so easily...& it's like everything after that is a fight.

Just to take the memory out of the equation for now, drop the divider to 100.. Report back and see.. If you were @ 1.45 running 2.5 stable, you will easily have 2.6ghz in that chip @ 1.55 ( most likely )



My hpyer X which would run 2-3-3-6 @ 200mhz in my nForce 2 board, needed to be run @ the 100mhz divider to get a decent overclock..

Find the MAX CPU first, then mess with ram speed and timings..

Well there isn't a need for 1.6v If he is solid @ 2.5 with 1.44v..

It's something else limiting you n7.
 
as I said, there are others who've hit a wall with the venice chip as well. I was stuck at 2500 1.45v also.

Did you check out this thread?
 
I have no interest in running my Venice @ 1.6V. That's too high IMO, especially since i'm hitting rather warm temps of over 55C under load.

I dropped my vcore down to from 1.450 to 1.425 + 8.3%, since the former was fluctuating up to 1.58ish, which i don't like.

I am priming at 10*260 right now, but tomorrow i will try RAM @ 100 with even looser timings to see how high i can get the CPU.

Although i had hoped for more, i will be very happy if i can even sit on 2500 MHz.

Edit: i don't get why i am getting such high temps.
Just comparing to people in the Venice OC thread, it doesn't make any sense.

I know the Zalman 7000s are better for silence than cooling, but i still don't think 57C should be normal under Prime load :Q
 
Hmm...a new problem has developed now.

It seems my Audigy 2 ZS doesn't like something about running 10*260.
I ran Prime all night, & everything seems great @ 2600 MHz except for playing UT2k4.

I can play music & everything great, but when i go play UT2k4, the audio freezes & locks up the game.
Also, when i go into the audio settings to turn on EAX in UT2k4...i get another lockup.

Is there any utility out there that shows what frequency the PCI bus is running at in Windows?

Hmm, sounds like your problem is what I read somewhere that you have to disable DEP under your performance tab in WinXP with that game. Or there may be a new patch out for the game?

I believe A64 Tweaker shows pci bus speeds.


 
Thanx...A64 Tweaker does not show PCI bus speeds though.

I am well aware of the DEP + A64s + UT2004 issue...that's been fixed with all the newer nVidia drivers...or are you talking about something else?

Set your AGP freq. to 67mhz to put the PCI/AGP lock into place.
 
Thanx for caring 🙂

I've left it at 2.6 GHz for now.

I've had the AGP set at 67 since the first time i ever booted it up, so that's not an issue.

I thought maybe the PCI slot wasn't locking somehow, since i am still locking up in UT2k4, & it's always the audio that first locks up.

I honestly haven't had time to fiddle around with it much the last little bit....or you could say i've been lazy when i have had the time.

I am gonna try playing some UT2k4 with the Audigy removed & see what happens.

The one thing that's really bugging me is the temps.

I don't get how at 50-58C under Prime load, the heatsink (even at its base) can feel barely warm, & yet the CPU be so hot.
I would think i did something wrong when installing it, yet i know it's on solidly above.
When applying the Arctic Silver, i put a little bead on & spread it slightly.

I later realized it should be just left as a bead, but the little spreading i did in the center part is about the same as letting the HSF squish it out, so i really doubt that's an issue.
 
Are you still using the Zalman?

What kind of CFM does that put out?

I am 55C loaded @ Prime 95, and wouldn't even be concerned if it was 59c or 60C..

I am more confortable with 58-60C, than putting 1.6+V into it..



 
are you getting 2.6ghz as well? thats where I am stable at. I can boot to windows and run pi on 2.8ghz but prime fails instantly.

right now I am running prime at 2.65ghz, 1.58v, 46-48C
 
CFM? No idea.
I am using the Zalman CNPS 7000B-AlCu LED. That's all i know.
The temps are confusing the heck outta me. Yesterday i was idling at 33-36C. Today it's idling at 42C 😕 The weather is a bit warmer today than yesterday, but not by a lot. Not 8 degrees anyway...
Under heavy Prime load it hits 58C :Q

ericlala: I think i have more in this CPU than 10*260, i just have to quit posting here tonight & test around some more, lol 🙂
 
Well, 10*260 (2.6 GHz) is going to be what i run this baby at.

Anything higher requires too much vcore to bother with (expecially with my temps).

I should have done this first, but i now just have to determine what the best timings are that i can get out of my RAM, & what speed i can get it to. (I've just been running it really loosely)
