Having trouble being stable at 2.8ghz with Neo4-F & Opteron 148 - Page 3

post #21 of 30
Heres the perfect example of what i was talking about, ur vcore mite be set to 1.497v but once u ran a test it goes lower im at max vcore 1.59 volts but its only on 1.53 1.55, but once stability test was ran it goes lower. so the culprit on ur stability issue could be ur vcore voltage dropping.

GOOD INFO. I'm running the program here at work as a test. Do you run the "test" section first then the "Torture" section? What's the difference?

I think you're right about the vcore and stability. So probably what's happening to me is although it is set to 1.497 in the bios, its dropping due to using the special vid option (which I heard drops the vcore whenever it senses the voltage is not needed). I've seen it go as low as 1.43vcore in Core Center program that MSI gives with the motherboard as a monitoring program.

So maybe if I set my vcore to 1.55 or 1.6v, I'd be safe as long as my temps don't get above low to mid 50c's.

I'm just so curious about what others with the Neo4-f board use for the nf4 chipset voltage when overclocking.

You should only need to run the Test as the Torture will just continue until manually stopped (like Prime95).

The Special Vid setting shouldn't drop the voltage when not being used, that's Cool 'n' Quiet. Make sure that this is disabled in the bios if not already.
The Special Vid just allows more precise voltages to be used instead of entire jumps and allows you to set more voltage after the last vcore setting

Oh, then what I heard about the special vid on the msi oc forum was not accurate. I DEFINITELY have the cool and quiet disabled, as well as the spread spectrum settings. But still the Core Center monitoring program shows the vcore flucuating from what it is manually set at in the bios (1.497)+to as low as 1.44 when running prime.

Gotcha about the "test" or "torture" options then. I too did not see the graph saved under the graphs folder in the program folder for OCCT. My computer here at work is an older INtel 2.5 but ran the program fine (but this computer has no overclocking).

Do you think this program is as good as Prime for stability? I'll try it out at home tomorrow. It will be great if I can get results on a tested OC without having to run the PC for hours on end to find out its failing.
On a side note, for Prime, how long would you say is good to assume you have a stable OC? 8 hours? 12 hours? Some people say 24 hours?

I'd say 8 hours is okay for Prime, but others have different views Eg. 24 hours. Depends if your system is always on etc.
Prime or the OCCT Torture are more accurate, as you run them for much longer. However, OCCT Test is an excellent indicator of system stability and I would rely on it for CPU stability at least.

I was just doing some reading on this A64 tweaker and may try that this weekend for different timings for my memory. But I guess first thing to do is turn the memory down to 100 right? Then if Prime or the other program fail, its due to the CPU being not right, correct?


In case you're interested, these Opty's are going way up in price all of a sudden. Probably due to everyone talking about how great they are with overclocking. I bought mine last week for $216 and within one week, the OEM Opty 148 went up to $247 or something on Newegg.

As far as the A64 tweaker, you have to key everything into that manually right? I see ALOT of settings there, but all I really know about with memory is 1t or 2t, the four timing #'s (i.e. 3-4-4-8) and the voltage.

Gentlemen -
I've reached a satisfying OC finally. As you guys suggested, I bumped up the vcore from 1.497v to 1.55v to see if I could be stable for more than a few hours. Here are my results:
-255fsb using 4x htt mult
-11x cpu mult @ 1.55vcore
-Mem @ 2.65v with 3-4-4-8 1T running 1:1 with fsb
-nf4 chipset voltage 1.6v

CPU LOAD TEMP ~45 to 46C
CPU IDLE TEMP ~32C

Ran stable with above settings for 20 hours in Prime 95. This is good enough for me. I think the 46C is ok for load temp.

good for u now bump up the fsb to 264 x11 and lower the htt to 3x and find out if u an be stable with 2.90ghz. oh yeah since we both have the same setup DO NOT run 3dmard06!!! i downloaded it and tried it today for some reason my computer turned off while it was doing the cpu test, and now it wont boot up..

I will try out the 264fsb tonite. I did some reading about loosening my timings a bit from 3-4-4-8 1t to 3-4-3-10 or something to get a higher DDR speed while still keeping the 1:1 ratio. I think I did try going higher with the cpu to 2.9 over the weekend but it failed in prime almost immediately with the 1.55vcore. Not sure if I had the htt to 3x or 4x though.

Thanx for the info about the 3dmark06. I only have used the 3dmark 01 and 05. I'll stay with those.

OFF TOPIC:
I had a major computer task over the weekend. I bought a USB hard drive and wanted to install XP on it. I don't think that is possible even though my bios has the capability to boot from a usb hard drive. Although XP installed on the usb drive fine, we I went to setup XP on it, the drive will boot briefly like its loading and then give me the BSOD. To make a long story short, I tried to repair windows but chose the WRONG DRIVE and it messed everything up that I couldn't even boot to the drive anymore. I had to repartition............OUCH! Took all day to reinstall drivers and programs.

As far as stress testing and stability for software, I only have been using Stress Prime 04 and Prime 95 and OCCT. For mem testing, I only used memtest. Do you use anything different?
