Please help me OC my 1100T/Antec Khuler 920. Will be uploading VIDEOS!

[crazyponytail]

Hello guys!

I hope you can help me OC my 1100T. I will want to try to get the best out of it. I will upload videos for everything I do. I know basics of overclocking, I have read guides. But it never works for me, maybe its that im doing something wrong or the chip just wont take it. WE WILL SEE.

I just need your help to verify if its me or the chip that is faulty . Otherwise I will just change the mobo and the cpu and get an intel i5 or something. In other words I want to upgrade my set, but I cant have this cpu at stock if I will do so.

So lets try to OC this to the top and I will be so grateful for all the potential help I can get.

Here is my first video:

SPEC:
msi fxa 990 gd65
amd 1100t be with Antec Khuler 920 liquid cooling.
kingston hyperx 2gb (8gb total)
650w PSU
xfx HD6870 be

So first stuff. Should I run memory at 1600 or 1333. Are we going FSB clock or just multiplier. Guessing I should disable turbo clock as well.

Starting at the beginning...

I copied and saved this since it starts off at the starting place.

With these CPUs you would need to be concerned with and deal with certain things when overclocking:

The first thing would be to download the overclocking software tools: CPU-z, HWMonitor and Prime95.

The next thing to do would be to check core and CPU temps at stock frequencies and voltages to get an idea of how much overclocking headroom you have from a temperature standpoint, which is the main limiting factor.

To check those stock condition temps: Open HWMonitor on your desktop and adjust the slider and frame so you can see the core temps section and the voltage section. Leave it open while you run the Prime95 blend test for 20 minutes. When that is done, attach a pic of the HWMonitor interface with your next post. To attach a pic, first crop and save the image to disc using Snipping Tool in Windows Accessories. Then click on the Go Advanced button at the bottom of any new post window. When the Advanced Post window appears, click on the little paperclip icon which will load the file browser and upload tool. The rest is obvious.

Next you need to be able to:

1. In bios, first disable: Cool N Quiet, Turbo, C1E and C6.
2. In Windows Control Panel Power Options configure it to High Performance.

These first two measures should disable all the "green" power saving stuff that cause erratic frequencies and voltages.

Then In bios, you will need to be able to manipulate:
1. CPU core voltage
2. CPU multiplier
3. CPUNB voltage
4. CPUNB frequency (may be expressed as a multiplier)
5. And perhaps, memory voltage

If you can locate those controls in bios you will be off to a good start and we can advise more specifically with regard to their adjustment. The terminology you encounter in the particular bios you are working on may vary somewhat from what I have used so be aware of that.

If you have a CPU with an upward unlocked multiplier, now just start increasing your CPU multiplier by .5x.

After each increase run a 20 minute Prime95 blend test to check for stability.

Always have HWMonitor open on the desktop to monitor core temps. Max stable core temp is typically 55-58c, somewhere in there.

When you first fail the 20 minute Prime blend test, increase your CPU core voltage by .025 and retest. If you still fail, add another .025 vcore. Then retest, repeating the pattern outlined. Stop adding vcore when your reach 1.5 or core temps exceed the parameters mentioned above.

Failing the Prime test can mean blue screen, spontaneous restart, lockup or one of the Prime core workers dropping out. Post back after you have added two increments of vcore or hit the mid 50's core temp wall. When you post, attach pics of HWMonitor from your last Prime95 blend run and give us a report.

Okay so I did the first stresstest.

My cpu vcore is constantly running at 1.528. I guess its because its set to automatic in the bios. But this is kind of stupid I have to say.

So check the results, what do you think?

EDIT: I am currently doing stresstest #2 at 3500Ghz. I set the vcore manually in bios to 1.37 but it keeps going up to as far as 1.424 anyways. Is this normal, am I getting something wrong here?

FYI...

For nearly 2 years now we have more or less suggested here in this forum section that people would do better not having Biostar and MSI AMD motherboards. They gave some real problems for many users.

That means we or at least I know me for sure are not famiilar with the bios in that MSI motherboard. You are the fourth person in about a month now to come in AMD CPU section and ask for help with an MSI board. Before that I don't remember 3 MSI boards in at least 18 months. Now we move on.

It would be nice to see some good,clear pictures of the CPU configuration section of the bios of that mobo. Where you set CPU Freq, CPU Vcore, CPU-NB, CPU-NB voltage and the like.

It sounds like that board on AUTO is over-volting. Now when you set 1.375V to cpu which is only about default most of the time...then another cpu Voltage called LLC or load line calibraton is adding voltage as the cpu voltage drops under load. Many boards do not add enough LLC volts or the add too much or they do not have the amount of LLC adjustabe exactly as need be.

So accurate bios pics would help dramatically. But something like LLC or Vdroop control or such is what you need to find for cpu voltage. Luck man.

Okay. Thanks. Im currently up at 3.9Ghz and at the second vcore raise for 3.9Ghz vcore1.4153 (i think it was), meaning it failed 2 times on 3.9Ghz. But it seems to be managing the 20 minute stress test now.

I will upload a video and some nice quality photos of my mobo bios in about 2 hours.

Thanks alot!

Here is a video of my bios:

(I think 480p quality is available as well)

I disabled MOTHERBOARD LED CONTROLL and EUP 2013 in the eco section of my bios settings, you can see it on the photos and in the video.

Like I said, the vcore is no longer at automatic but it keeps giving more than what I have it set to.

Here are the photos:

 

[crazyponytail]

Update:

I have raised the vcore 2 times now and I fail the test. The vcore is the same as at the photos. My latest 20 minute test that was stable was at 3800 (@3900 now, unstable.)

It passed the 20 minute mark at 3900 but later on crashed, dont know how long after since I wasnt at the computer. So it can do 20 minutes at 3900 but isnt stable in the bigger perspective.


Here are the screens for that test:

 

[trents]

Your temps are not excessive and you should be more stable than that at 3.9ghz and a vcore of 1.458 I'm thinking. Could you please attach pics of CPU-z tabs "Memory" and "SPD"?

 

[crazyponytail]

Here are the prints of my memry and spd tab. It was actually unstable at 3800mhz now as well I noticed. It passed the 20 minute test but later when I was playing video games it crashed.

I got bluescreen. So i raised the volts to will see if its better now.

 

[Hicksimus]

I had thought consensus was that the top core temp you'd hit before instability with these is 55C while some claim 62C.

Are you certain that your 920 is making good contact with the processor? Your 920 temperatures are very similar to the temperatures that I get from my cheap old Hyper 212+ but I thought your 920 should outperform it by a fair margin.

Hmm I think so. But I mean. Its a stresstest and the vcore is at 1.46. But maybe I should take and check the rig. But that shouldnt be the problem with the OC being unstable. The temps arent too high.

I could go up to 1.5 something vcore and keeping the same temp btw. (During my first stresstest, having the vcore set to automatic it maxxed out 1.5 volt.

Whenever I touch the multiplier this cpu just wont get stable. : /

 

[Hicksimus]

Do you have the software for controlling the fan on the 920? You could see if bringing the temperature down is useful. IIRC you should be able to because the 920 fans can scream.

 

[crazyponytail]

Just want to update the thread by saying that I got a stable clock of 4GHz now. I had to disable 2 cores and now it works.

Or at least so I think.

Another weird thing that happened was that I got fps problems after the clock. I was down at like 60 fps when playing dota 2. But I fixed that by raising nb freq to 2800MHz instead of 2100.

 

[johnny333]

I run my 1100T at 16.5x225 at 1.40 volts. At 650 your power supply looks on the light side what brand is it? I would want a good name and 750 at least.

 

[Geonerd]

try bumping the DRAM voltage a tenth or so.

 

[adams1029]

Little more NB might help give it some stab. I forget what I found stable for my brothers 1100t I belive it was around 3.8ish. Also give it more then a 20 minute test with p95. I tend to aim for a hour if it's a short test. Just my option.
