Hello I just got my system built and i been try for a day now to get a stable overclock of 4.5Ghz will settle for 4.4ghz but i just can't same to be stable any where but on stock on my new 990x.    When i got it i try just changing the Clock ratio to 32x any even thing else on auto and system will but a freeze on windows 7 booting logo  and no BSOD.  So i started over and i try different things like raising voltages and such but no luck.   I get a bsod after a stress test most of time on at 4.2ghz even bout boots fine.
 
 
I really need a starting port on with to start with like adjust cpu clock ratio or cpu host freqs or or uncore or what?  Guides have not helped me much that i have goggled.
 
Once i get a starting point i can post errors and Bsod screens hot and stuff but i have  not even been able to get of 3.8ghz stable.
 
So Please Help
Thank You

I did as the guide said even know i using a 990x and folloed it  to the letter and i clocked save a it rebooted and screen where blank and evga board display said 69 then 00 then e8 so i cleared cmos and will try it again with less vcore i think.
 
Boot after i flood guide i boot to black screen no post nothing so i had to clear cmos and start from scratch.

I am  trying it agin now.

all i want is 4.5Ghz Stable.  Witch should be easy with my 990x and my evga ftw3 and ram is XMS3 DDR3 1600 All dimms full so 6x2 12gb total.   and 2 gtx 570s stock and 64gb ssd.

Any one?

Your first post was only an Hour ago...............................

cooling???
 
4.5 on gulftown is nothing like 4.5 sandybrigde. It is significant, not easy. (at least not easy to be totally, ie linpack stable)

Oh sorry about that.  I am on air cooling on stock setings cpu under load the in a nice 110.4F.   I would be happy with a sold 4.2GHz stable. but i cant even get close.   I tryed just trurning up the cpu multi to 29x and evey thing else on stock and i can be stable. but any more than 29x like 30x and all setings on auto it frezzes at windows start up logo. No bsod thu. I have read i should be able to get 4.2 easy on my 990x. but i just cant seam to get stable.  i would like to have a starting point so i can boot ok on 4.4 in cpu-z then then if i get error will go from there. and post it so i know what to rase ur lower in bios.
 
Sorry about typos no atuo correct.
Thank You

Have you read that yet? It's a very good primer.

Yes i have read it i got my over clocking over view from that guide.
But it did not help. because i tried from there starting point and no luck.
 

Ok i make a starting point. i raise my cpu multi to 30x and evey thing else on auto and ram is on xmp 1 by the way.

did you increase vcore?

Disable XMP, enter your Timings and Voltage manually. Never use the XMP Profile and overclock at the same time.

 
Moving thread to the appropriate section of the forums!

ok i am on 32x Memory is 1057 / 2:8 i changed 8-8-8-20 to what xms3 say 9-9-9-24 and dimm voltage 1.650v that what corsair says. 
 
Now i set my cpu Clock Ratio to 32x with Vdroop every thing is set auto.
Bios says target 4266Mhz 133x32 
Target Memory 1067Mhz.
I will save and try to boot now.
 

Ok now when i boot Starting windows comes up with the little colored ball that turn in too the windows logo and it just freezes there.
 
What due i do?  I mean do i rase ur lower some thing in bois
 

Ok good news i can boot into windows with this setting below.
 
BSOD system service exeption or freeze on desktop.
 
cpu clock ratio 32x 
Vcore 1.30v rest on auto
 
what should i rase?
 
 

 

Im in windows now and posted this on my pc. that im overclocking. i will run prime now for a wile.

With that setting above i BSOD if i try to run prime what now?
 

Check your temps ALWAYS, but raise vcore a bump and try running it again, if it goes longer before BSODing, then raise it one more.

I have a 990x aswell but on a different board. From the research I've done on the 990x and from my own tests I've found that they best preform with multiplies of 31, 32, 33, 34, and 35. With water cooling I can OC to 4.6 Ghz @ 1.39v.

Just like every overclock you do you have to start from the bottom and work your way up. Set you multi to the lowest one, your dram freq to the lowest one and try to find your highest stable bclck and raise your vtt accordingly.

Ok will give it a shot. i will post screen shots off error's and bios here too.  if i have more questons

Take a little time and fill this out. Then we can help you better.
