What's going on with my OC?

So I've got the rig included in my sig. I can't tell what's at fault but I'm pretty sure it's hardware at this point. I get random freezes and reboots. I suspect either my mobo, RAM, or proc.

My rig is stable at 2.45Ghz stock core but the problems start to occur at 2.5Ghz with stock Vcore. I've got a 9500 on the way and so I can up the Vcore if necessary but what sounds like the problem?

At 50% Load w/ a 2.45Ghz clock, Everest is reporting 40s for the cores, 33 for the CPU, and 57 for the motherboard. It gets a bit hotter for both the core and the CPU and about 5-10 degrees hotter on the motherboard. Not sure where the diode is for the M2N32.

My goal is 2.8Ghz but I would be satisfied with 2.6 or 2.7. ALSO, please keep in mind that this is my first time OCing.
 
its unstable... you need more vcore. your temps are fine, bump it to 1.425 and see what it does.. just monitor temps.

also i am assuming your ram is on a divider so you know this isnt your ram... right??????
 
My guess would be the HTT multi needs to be lowered. If not that then the ram one

HTT may be called LDT. Can be a number like 1000-800-600-400-200 or a number like 5 4 3 2 1. You need 600 or 3.
 
I know it's not my RAM cause it passed several rounds of Memtest. The HTT is low considering that [H] was able to make it go upwards of 300. Is it possible to change my RAM divider? Currently mine is CPU/6, so if I can make it CPU/7 I wouldn't mind. I'll try upping the Vcore later. At 1.425, can I get up to 2.6?
 
Ok, I bumped up the Vcore to 1.38 and it seems stable enough. What's an easy way to determine the absolute minimum voltage for the Core so as not to do too much?
 
I think you're trying too hard to have as little Volts as possible. Bump it to 1.4.

Although the guide I'm about to suggest is for 939 based systems (which will only affect how you deal with RAM dividers/settings), please follow it. It will guide you through finding the maximum speeds each part of your hardware will do (CPU, HTT, RAM), and then you'll assemble a final OC.
Use Orthos instead of Prime95 to test system stability (run it overnight).
With good air cooling (as long as temps are good), 1.5 and 1.55v are fine.
 
I'm at 2.8Ghz stable rocking a 1.475v vCore. Now I just gotta figure if I can push it to 3.2Ghz and be done with it. ^_^

Doesn't seem reasonable.
Good Luck though
 
I am stuck at 281 for the HTT. I can't get it up to 3.2Ghz but I am resting comfortable at 3Ghz. My problem now is my RAM. I have to clock it down to DDR2-684 from DDR2-880. It won't POST otherwise. I think I can make it post at DDR2-880 at 5-4-4-10, would that be better than the DDR2-684 at 4-4-4-10?

That's a tough one for me anyway, I'm not a memory timing expert.
I say test them both out and that will tell you.


I would guess this one is better though.
DDR2-880 at 5-4-4-10

how about u test it out. open up a memory benchmark, sandra or whatelse, and then run some bandwidth benchmarks and latency benchmarks. you should be happy that you're even posting at 3ghz on a 4400+
 
Haha. Yeah, 5-4-4-12 at 3Ghz (DDR2-857) and I can do almost 1GB/s for the Memory Read Benchmark. Now I just gotta tighten up my timings and then see how low I can get my noise. It gets to 60° C at load on each core but considering it can go all the way to 70°, I'd say it's good. Stable with 4 hours of Orthos.

Needless to say, I think it's a successful OC. ^_^

60 at load on bothcores on air for that big an overclock isnt bad at all.
 
Blah. Now it seems like one core is failing Orthos after about an hour. What does that mean? Will I have to scale back my OC?


EDIT: Now it's stable at almost two hours...

EDIT 2: And it failed at two hours on a different core. Hmmm. Maybe a higher voltage?

If orthos fails at all, its not a stable OC. What speed is your processor capable of? RAM? HTT? Follow the guide posted above to doing this if you haven't already.

Have you set your HT Link (also called LDT multiplier) so that it*HTT is less than 1000mhz?
 
HT is at 1092 but I figured that wouldn't be a big deal. I'll kick it down a lil bit. Also, RAM is rated for 4-4-4-12 at 800Mhz but is okay at 5-4-4-10 at 860Mhz.

The HT can cause issues when run beyond 1000Mhz, and it does almost nothing to performance to run it higher or lower (other than just causing stability problems).

Have you tested the RAM in memtest86 or by running Prime95/Orthos/SP2004 at those speeds?
 
Thanks, Quad.

I had gotten though 3 passes of MemTest but going up to 1.5V on vCore and 3x multi for HT has helped. I'm 6 hours strong in Orthos.

varying degrees of stability though. for example a cpu could still fail one of these tests even at stock just due to a random bit error. i think sometimes people spend a little too much time testing for super stability than they do for using it for gaming working et cetera.

Glad to hear I helped :D

How are your temps doing? What cooling are you using?

if it fails, theres an issue.

if you run a system that fails prime95 in a few hours, you'll soon find instability issues cropping up. BSODs, corruption, the whole lot. Trust me, if you've got an issue with prime95, it's a better idea to either back off the OC (if you don't want to play with it anymore), or work at it harder.

They maxed out at 62°C but are sitting comfortably at 60°C across the board. I'm using a Zalman CNPS9500 AM2, it matches me case theme (Green lights) and looks great. Amazingly enough, I just used some Dynex thermal grease from Best Buy because I forgot my AS5. I couldn't be happier! ^_^

Well the temps seem fine, although you are reaching the area where heat could pose a threat. Perhaps even a remount with some AS5, making sure you use only the amount shown here could drop those a little.

Sounds like you're doing well though.
 
Hmm. The last two Orthos runs have errored out somewhere around 12 hours... I'm gonna try dual instances of Prime95

They're the same program, orthos just has a fancy interface.

good work though on the stability! What are the settings and temperatures at now?
 
I decreased the voltage cause I think it was too much down to 1.475V and turned the fans back up so it's sitting comfortably around 60° C. Orthos had errored out at 13 hours. Should I try and get to 24 hours or is it inevitable that I'll error?

EDIT: And one of the instances of Prime errored out at 29 min. WTF?

That means that the chip needs more voltage to be stable at whatever settings it's at. If you try remounting with some AS5 using only the amount shown above, you might be able to lower those temps. What was the voltage at when you errored at 13 hours?
 
Thin Man said:
The aforementioned 1.475V which makes it even weirder. :p The things we do to OC!
Click to expand...

How are temps at 1.5? I still think you should remount with a tiny amount of AS5 to see if your temps will drop.
 
They max out at 63° C which I'm comfortable with cause my processor is rated for up to 70°.

At 1.5V, it failed at 3 hours. I'm gonna kick it back down to 1.475V and call it stable.
 
I apologize for resurrecting the thread but I gotta figure this out.

Occasionally, my computer will freeze my processes one by one. One program will stop responding, then I'll try opening Task Manager. If I already have it open, I can't end anything.

It really sucks. My question is: is it my processor or my HDD or my RAM? They've all tested well but maybe I missed something.

You're going to have to figure that one out part by part. It most likely isn't your HDD, but it could be any one of the other parts. Have you run memtest86 at least overnight at whatever settings you have it on? How about Prime95 on the voltage/frequencies you have your CPU at? Also, did you ever remount to try and lower those temps, as they're towards the higher end of the spectrum?

If you'd like, we can chat via AIM.
 
Never remounted but right now I kicked the OC back to 2.9Ghz. I'm happy on the encoding spectrum and I'm gonna try Orthos after it is done. Orthos would fail around 12-13 hours at 3.0Ghz, is that stable or unstable?

Sure, message me with your SN.
 
I remounted it with my AS5 and am priming 2.8Ghz. I just wanna say thanks to Quad for all his help. Damn! 10 degrees cooler (50° C). He was right :D

I thought those temps sounded high!

Good stuff man, I hope all goes well.

Up to 52 at max but 57 minutes until 1 day of Orthos stable!

Edit: Orthos stable!
