Solved BSOD After using ASUS Sabertooth 990FX MOBO OC Utility.

What you linked to is probably what you have. On cpuz, the memory tab shows what it is actually running at. The SPD tab shows the different frequencies and timings it can run at. If it has an XMP value, that will show you what it can do, but XMP is an Intel thing. With AMD it has to be set that way manually. In CPUz, if you were looking at the 'max bandwidth' section, that just tells your motherboard what it can start it at so you can get into bios to set the proper values. It does not mean that is actually the max bandwidth. On the side of the ram sticks is a white sticker which will show you the frequency, the first 5 timings and the voltage to set in your bios.

Good job on the Prime run.

Thanks, although, I don't think I really did much. I matched my numbers to that RAM setting that was posted in the ASUS page on here.

Here is what CPUID says now.

 

[huonub]

Now I went back into BIOS, set everything back to default. Then I manually changed DRAM from 1333 MHz, and set it on 1600 MHz. Now this is what CPUID says.

So Am I running at 1600 MHz? or 800 MHz? BTW, thanks for all your input, and being so patient with me.

 

[essenbe]

They are both the same thing. DDR3 is double data rate, so it reports 800 which means double or 1600MHz as it should be. I realize when you first hear it, it's confusing but after a while it's not so bad. But, CPUz posts double data rate which is 2 X 800 or 1600. (give ot take a couple of numbers at times) So, if the memory tab was to say 667, that would mean it's running 1333. gangiry will be on in the morning to us. He is in the UK and it is 6 hours ahead of us. He knows a lot about AMD boards, I don't. I can help you with some basics such as CPUz and running tests, but he needs to give you specifics. He may want you to run memtest again. Once you change ram frequency, timings and voltage, that changes a lot. Or he may not. But, to overclock properly, you spend many hours running stability tests. It is not a set it and forget it thing. All CPus and motherboards are different, even same make and model. So every board and chip will need different settings. That's why you run so many stability tests, to see if it needs tweaking a little. You have to be very patient to overclock properly and never use the software the manufacturers give you. Overclocking is not for the faint of heart.

Yes definitely! I am glad this community exists. I appreciate you help. Awesome, so now I am running at 1600. I am running Prime95 again to see if running 1600 is stable. Quick question, am I suppose to burn memtest86 to a cd? I clicked on that link that was provided, however, I didn't see a .exe, just .iso. That is why I opt'd out of using memtest86 and went with Prime95.

 

[Tews]

Just burn the ISO to a cd (burn as an image file) then boot your cd/dvd and let it run overnight. Post your results.

 

[essenbe]

There are 2 tests. Be sure to use memtest86+ and not memtest. Most of us would agree on that. There are several versions. The .ISO file, put a blank CD in your drive and double click it. Windows image burner will come up unlless you have other image burning software. Burn it to the CD, then boot from the CD and it will start automatically. It will take quite a few hours to run a full test. I always run at least 8 passes. Each pass consists of 10 tests. Each pass tests something different. It takes about 8 passes to run a full test. If you see an error you can stop, the test failed. We'll tell you what to do then. I usually run it overnight. I start it and go to bed, let it run all night. When you get through, keep the CD. You will need it often. They also have a version which will burn it to a USB flash drive. You can use the one time boot key or set bios to boot from the DVD first and hard drive second. Either way is OK. I'm not sure what your one time boot key is, but I have an Asus board and it is F8. When you see the asus logo start tapping F8 and you will se a list of every bootable device on your computer. Use the up/down arrows to highlight the one you want and press enter. You may already know that, but just in case..... But either way you want to do it is OK. On another note. Before you really start overclocking read your manual and find the ways to reset CMOS, you may very well need to know.

Morning folks! Sorry for the delay

Cheers Steve, You explain things so much better than i can. Fancy a job as my translator? :roflmao:

Regarding AMD and XMP
Asus boards have implemented a way of applying the xmp profile with a setting called D.C.O.P.
In your bios on the extreme tweaker tab if you click the AI Overclock option you can set either maual, offset or D.C.O.P. If you set D.C.O.P you can then select the xmp profile for your ram.
Demonstration of D.C.O.P
I've never actually used this setting though and just apply the timmings manually.

huonub just a heads up regarding AMD temp's.
In an earlier post you stated that your cpu temp never goes above 34c and idle around 12-16c.
Unless your ambient temp is about 5c then this is pretty impossible as you can't cool below ambient on air cooling unless you live in a fridge or other super cold place
AMD cpu's have some wierd way of messuring temps and it's basically some calculation of mulitple numers. To get your idle temp you check the socket temp which will just give you a rough idea,
Look at the core temp for load temp's but this will only be accurate from about 40-45c and up.

Have a read of this which explains it a lot better than i can. AMD Temp Information and Guide

If everything is stable at stock settings and your ram at its rated settings then you can move on to overclocking your cpu. Change the Windows Power profile to performance.

If you haven't already saved the current bios profile the do so as if you need to clear the cmos yu can just reload and carry on where you left off.

Go into the TOOL tab in your bios and select "Asus oc profile".
Enter a name for the profile,
Enter the number if the profile position you want to save to and click enter.
Hit enter again to save it.

Next you want to go into the "Advanced" tab and select "Cpu Configuration" and set all to disabled.
Cool n Quiet
C1E
SVM(Unless needed for running a virtual machine)
Core C6 State
HPC Mode(currently testing enabled)
APM Master Mode

Hit "F10" "Enter" to save and exit and reboot back into the bios


Next go into the "Extreme Tweaker" Tab and set the following as a starting point.
"AI Overclock Tuner"set to Manual.
Cpu ratio = 21 for a cpu frequency of 4.2Ghz as a starting point.
AMD Turbo core technology = Disbaled
Cpu bus/peg frequency = 200
Cpu/nb frequency =2400
Ht Link frequency =2400(Bulldozer likes Cpu/nb,HT LINK to be same where Piledriver/Vishera likes higher HT link)

Scroll down to "CPU & CPU/NB Voltage mode and select "Manual"
Cpu manual voltage = 1.4v(The actual voltage applied will be slightly less due to v-droop.
Cpu/NB manual voltage =1.2v(Never leave this set to auto when overclocking on Asus motherboards as it will give way too much voltage).


Scroll back up to " Digi+ VRM/Power control" "Enter".
Set Cpu and Cpu/nb Loadline callibration to "high"
CPU Current Capability =130%
CPU/NB Current Capability =130%
CPU Power Phase Control = Optimized
CPU Power Duty Control = T.Probe

Hit F10, Enter to saved and exit to reboot into windows.
Open HWINFO64 or whichever software you are using to monitor temps(ONLY ONE) and run 20mins of Prime or 5 passes of Intel Burn test. If you crash,bsod or your system just freezes just go back in the bios and raise the cpu voltage by 2 increments.
Reboot and stress test again.
If it passes without crashing or anything then go into the bios and raise the cpu ratio by 1 increment, reboot and test. then it's just a matter of rinse n repeat untill it either crashes or your happy with the overclock. Once you reach an oc you're happy with run your stress test for a few hours if using prime.

REMEMBER TO KEEP AN EYE ON THOSE TEMPS. 62c IS THE MAXIMUM RECOMMENDED TEMP FOR THE CPU CORE AND 70c FOR THE SOCKET. DO NOT GO OVER 1.5V.

If you have any problems or there is anything you're unsure of just ask

Have fun!

 

[huonub]

Okay, I did exactly what you said. Everything looks nice, except Windows says 16GB installed(12GB usable). Is this a problem? I'm a bit confused at this. As of right now I am at 4.21GHz for CPU, and 1600Mhz for RAM. I am about to run Prime95. Then tonight, I will run Memtest86

 

[ganjiry]

Okey doke! Is your memory 1 single 16Gb kit with 4 sticks or did you buy 2 seperate 8Gb kits? It can cause problems if running 2 seperate kits.
Go into the advance tab of your bios, Select North Bridge and then go into Memory Configuration and check if a setting called Memory mapping(can't remember exact name) is enabled. If not enable it.
If it is already enabled then try raising your Cpu Vcore or Cpu/nb voltage a couple of increments. It will take some trial and error.
I'm not too clued up when it comes to memory though so somebody else may have to chime in for that.

If any of that help's get the full 16Gb showing and it has passed memtest then you won't need to run memtest again unless you overclock your ram. If after you memory is stable and Prime finishes ok you can up your cpu ratio untill it fails Prime. When it fails just raise the Cpu Vcore a tad. For 4.5Ghz using a cpu ratio of 22.5 you should be looking around the 1.440- 1.452v mark but all Cpu's are different and yours may take more or less.

I'm off to bed now though mate, knackered! No doubt i'll be up at silly o'clock though so i'll check in as soon as

 

[essenbe]

This is a tutorial to set a limit on how much memory is used. If ganjiry's idea does not work (it's memory remapping) try thid tutorial, just remember, it is written for the opposite of what you want to do. See #4. http://www.sevenforums.com/bsod-hel...ooth-990fx-mobo-oc-utility-3.html#post2536436
Also, check bios and make sure it shows all of your memory.

My ram is a 16gb kit of 4x4gb. Also, this is what I got after 7 hours of Prime95

BIOS is showing all my memory. During memtest and normal running system, it only shows 12 GB usable.

 

[ganjiry]

I don't use Prime myself so i'm not too sure about the prime results txt but to me its looks like you had a core or 2 drop which is probably down to too little vcore. What voltages and cpu ratio are you using?
You could try upping the Northbridge voltage just a couple of increments, As i said memory is something i know very little about, I had the same issue myself once but it was due to 2x 8Gb kit's not playing nice.

 

[essenbe]

Rounding errors are errors. The test basically runs mathematical calculations (Prime numbers, hence the name). It knows the answers and rounding errors means one or more of your cores came back with a wrong number. A real laymans definition. Usually, as ganjiry says, vcore increases will correct it.

As far as the memory, if none of the solutions worked for you, I would re seat the ram. If bios does not 'see' it, that means it is not detectabe. It has to be able to detect it for any fixes to work. If reseating does not work, I would pull 1 stick at a time and see how much is detected. Theoretically, when you pull the stick it is not detecting, it will read the same as it does now. So, pull the stick 1 at a time. If it is not the bad stick, put it back in the same slot and pull the next stick. Keep doing that, and replacing sticks in the same slot, until you find the offending stick. Next, I would mark the bad stick with a small sticker or something and remember the slot it's in. Swap all the sticks around with each stick in a different slot. If you end up with the same problem, pull the stick you marked. and see if you still show 12GB. If you do, that stick is bad and just RMA the entire kit. If you find that stick is not the problem, put it back in the same slot and pull the stick that was in the slot where the bad stick used to be after replacing the stick you marked. If that shows still 12 GB of ram, it is the motherboard dimm slot. I know that is a little confusing, but logical. If you have any questions at all, feel free to ask. If either of us know the answer, we'll be happy to answer. Otherwise we will be happy to find someone who does know the answer. What I am trying to do is determine if you have a bad stick of ram or a bad Dimm slot. That is usually done with memtest86. But memtest can't check the stick for errors unless it can 'see' the stick.

EDIT: ganjiry and I prefer AIDA64, but it is not free although there is a 30 day free trial.You can use whichever one you want. They will both work. AIDA just has many more features. When running these tests, always have your CPU temp monitoring program open and CPUz as well. Take notice of the Core voltage in CPUz while the test is running, it will be different than what you set in bios. We will be asking the values of both as we go along.

 

[ganjiry]

Thanks for the info Steve, Good advice mate! It's very much appreciated mate
I think all his ram is showing in the bios which is why i'm thinking voltages as 4 sticks is more stress on the imc but as you know it's all trial and error isn't it.

@huonub, Welcome to the stresses of overclocking you need the patience of a saint.

 

[huonub]

I fixed the ram issue. I set the voltage to v1.650 in DRAM, and I switched all the RAM sticks around into different slots(i believe re-seating them actually fix it). System now shows 16GB usable in Windows properties. So after reviewing the corsair ram guide, 1333mhz is v1.500, so should 1600mhz be v1.650? I got this number from CPUID. Thanks for all your help. Also, in terms of my cores dropping off. Which voltage am I adjusting, and by how much in increments? Thanks again for all your help and advice! You are guys freaking awesome.

 

[essenbe]

huonub, Please tell us what the values are in bios for your CPU voltage. FSB, HT link and the CPU-NB. If you can, tell us what those voltages show in CPUz during Prime. ganjiry will have to tell you the values that need to be altered, but he will need to know what the values they are now.

I'm glad you solved your ram issue mate
As Steve said though we could do with seeing your current settings for the extreme tweaker tab and load voltages/temps for your cpu.

 

[huonub]

Okay, give me an hour. I'll get them. from BIOS.
