e8400 c0 FREEZE OC 790i ultra SLI

post #1 of 20
Thread Starter 
Good morning Fellows!

Well, I have a build of my signature and I can't OC my Rig.

How can I OC. I try OC e8400 C0 - 3.2 Ghz / 3.6 Ghz / 4.0 Ghz
And when try this settings the system freeze when windows enter ( I login in windows).

And I don't Try 1.4v or more to enter a system.

Do you have a solution to my build?

I try a lot of things but can't OC It yet.
I know this a bad CPU to over, but is not impossible.

Thanks?

I generally not a proponent of trying voltages and stuff randomly. First, you need to do the following to eliminate any potential instability.
1) Make sure all your power saving options are OFF. This includes speed spectrum, any CIE state, etc.
2) Make sure your RAM is timing is set to manual and the timings are what manufacture recommended including manufacture recommended voltage. Also, go to your RAM multiplier and set it to unlink for now and set it at 800Mhz. I know this is slower than you like, but you first want to overclock your CPU without causing any instability due to RAM. You can later tweak you RAM.
3) Now set your multiplier to highest and increase your FSB to see what happens.

2) RAM is 2T, but i'm not using timings in manual. Why I have to use them in manual ?
It's unliked in my pc.
3)Ok

OBs: Could be my memory that Stuck my PC Start at windows "I'm logged in" at all?

Test with 2 ram"s only?

more plz...

1) RAM timing set to manual so that you can set them yourself. What does the timing shows right now? I do not know what your manufacture suggested are, but it should be something like 6-6-6-2T or something of that order. The reason to do this manually is to loosen up the timing. Too tight of a timing can cause instability during overclock.
2) Two RAM stick should help some as running 4 slots will definitely require more HT or Vtt voltage. But for now just try with all 4 and see what we can get.
3) You said it is unlinked. So that is good. What frequency are you running for the RAM? Even though your RAM is 1333 Mhz, just set it at 1066 Mhz for now.

Did not quite understood your "I am logged in" question....Are you saying when you boot your PC, windows freezes at some sort of "I am logged in" screen?

Ok!
1)Find It

I'm seek for my memories timings and find this.
_______
# DDR3-800MHz 5-4-4-8
# DDR3-1066MHz 7-7-7-15
# DDR3-1333MHz 9-9-9-24(27) Corsair = Stock
Voltage = 1.5 ~ 1.7 by corsair
I need to change tras; tref;etc too? Or should do manually?

2) HT =? vtt = FSB VOLTAGE... For now we set the memories at all ?
Find the real voltage for the OC ?. I leave the settings on auto...vcore.vtt.etc. all auto.
3)now my memories in stock settings.

I want Tell
Windows starts normal but after starting all programs, can't run cpu-id, this stucks after load all. freeze! Understood?

I hope I am making sense of all these....
1) It seems you found the RAM timings. Set them to 9-9-9-24. Use the following guide:

http://www.tomshardware.com/reviews/...z,1200-11.html

2) HT is another way of referring to Vtt. So, we will just call it Vtt. You will have to set RAM timings manually first. I am assuming you have now set the RAM timings. Also make sure you set the DRAM voltage to 1.6V or whatever is recommended for your particular RAM. 1.6V is decent voltage if you are not sure.

3) Change your Vtt from auto to 1.2V.

4) Now increase your FSB by 100 mhz and see if you can get into windows and no freeze. If no freeze, run Intel Burn Test with setting at maximum and number of times to 3. If no error, restart computer and increase FSB by 100 more. Post back once you are freezing again or getting blue screen or computer will not boot.

1) Yep!
http://www.bit-tech.net/hardware/200...24_1333c9dhx/2 Found HERE! Iwill mantain the 9 9 9 24 so ? Manually and 2T. Is fine ?

2) Voltage is 1.5 and is just fine. I Also this auto OK ?

3) vtt Is 1.2 ok! i will make that

4) 100 mhz ok. But I have a issue. When I put some value in fsb, save and return the auto settings put my Vcore to 1.3, in auto =(. Always.

1) Yep. you are fine there.
2) You can try Auto if it is set at 1.5V.
4) For now, do not worry about Vcore. If it is at auto, let it be there. If it sets it to 1.3V, that sounds a bit on the high side, but for now leave it alone. Increase your FSB by 100mhz and just boot into windows. So if your current FSB shows 1066 (guessing here), increase it to 1166.

EDIT: Do you what was the stock Vcore value?

Explained:

1333Mhz = 100 mhz = 1433?

And vtt = 1.2 or auto to...all settings in auto or vtt is 1.2 now ?
I think 100mhz will push 1.3vcore...I wait this don't freeze att!
Thanks at all !

I estimate your attention and want solve this. Continue!

PS:CPU @ 3.0 Vcore stock ...1.176/ 1.18 / 1.192

FSB to 1433 like you said. I agree.
Vtt manually set to 1.2V. DO NOT leave it auto.

Looks like leaving Vcore at auto puts too high of a voltage. Let us take if off auto. Set Vcore to 1.25V manually. DO NOT leave it auto.

Reboot and see if you are stable. Meaning no freeze.
