Windows not booting with new OC

[samqweqwe]

hello,
i have the AMD phenom II X6 1090T processor and the Asus m5 a97 pro. the bios for the asus mobo has 3 settings: power saving, normal and asus optimal. i have had it on optimal for while. optimal oc the processor for 3.2GHz to 3.7GHz. i have been trying to get this to 4GHz manually and i have but windows 7 does not like it and switches the computer off. I have tried a few different ways of getting it 4GHz but none of them work. I have been changing the CPU ratio, CPU Bus/PEG frequency and reducing the memory frequency as they are sensitive to OCing. When i get the CPU speed to 4GHz i save and restart the computer and then let it boot up but when it gets past the bios (which works fine) windows comes up with two options: windows repair and start windows normally. when i click windows start normally windows starts to load for about 1 second after the animation started and freezes. Then a blue screen with text flashes up and then it shuts down. I cannot read it as the computer is turn off straight away. as soon as i put it back to the original settings it works fine again.

how can I fix this problem?

Thanks in advance

Hi,

Seems like your new O/C is very unstable, have you tried booting in at 3.8/3.9Ghz?

I expect the problem is not enough Vcore but I don't know your temps and current voltage so that's why I'm suggesting you reduce the clock slightly rather than add more volts.

 

[samqweqwe]

i have tried 3.8GHz and i keep the voltages the same. the Temperature i dont think are high as at 3.7GHz on idle was ~28'C and on load i think was ~45'C. from what i know is that at 4GHz it runs at 45'C on the BIOS

 

[Rustyy117]

So does it not boot at 3.8Ghz either?

 

[samqweqwe]

no

 

[Rustyy117]

no

What voltage are you using for 3.7Ghz?

 

[samqweqwe]

im not sure, i think it would proberly be the defult voltage which i think is 1.225v.

 

[samqweqwe]

sorry its 1.4v

 

[Rustyy117]

Try a slightly higher voltage for 3.8Ghz, something like 1.425V.

If you can get into windows and start stability testing make sure your temps don't exceed 62C.

 

[samqweqwe]

what do you recemoend for testing. it finally got into windows

 

[Rustyy117]

Cool

I generally recommend Prime 95 for atleast 8 hours or AIDA64. Remember to watch those temps with a program like hardware monitor or real temp.

 

[samqweqwe]

i have speedfan is that ok

 

[samqweqwe]

while running the test how do i know if my ram is ok because they do not have thermometors

 

[Rustyy117]

Yeah speedfan is ok.

You don't need to worry about your RAM temps unless your really overclocking your RAM hard.

Providing your case has some airflow I wouldn't worry about your RAM temps.

 

[samqweqwe]

i think it is stable at 3.8GHz. it was ~52'C the whole way through for 11 hours. Should i take it up to 4GHz?

That's good, temps are acceptable and it's stable.

If you're going to try for 4Ghz then you'll probably need more Vcore again, make sure you stay below 1.55V

Try something alot lower to start off with though, if it doesn't boot in with 1.425V then try 1.435V ETC...

 

[samqweqwe]

thanks

I have 1600MHz RAM but when i OC the processor it goes to 1666MHz. is that a save OC?

 

[Rustyy117]

Yes it is safe, however I would make sure the DRAM and timings are what they should be, if you are not sure what they should be then you can check on the side of the RAM sticks (should be a small sticker with the info on it).
Also make sure that the overclock is still stable if the RAM frequency has changed, Prime95's blend mode tests the RAM aswell as the CPU so you can use that to ensure the RAM is still stable.

 

[samqweqwe]

I use AIDA64 and i see the CPU is at 100% as it should be during the test but the RAM is only on 25% usage. I have 3 sticks of 4GB. is the RAM being tested?

Well it is being tested but not heavily, Like I mentioned before, prime95's blend mode also tests the RAM, you can also manually enter the amount of RAM you want to be tested ( in your case you could enter 4000MB/4GB).

They're other programs that test RAM aswell like memtest.

 

[samqweqwe]

I'll try that

 

[samqweqwe]

is 64'C safe for the processor

 

[Rustyy117]

is 64'C safe for the processor

It's alittle too high, like I said before you really want to be staying below 62C, having said that stability testing will make your processor run hotter than nearly anything you'd use your computer for on a daily basis.

 

[samqweqwe]

that temp is during the test. it has been going for 20mins and so far it has not passed 64'C. it stays at roughly 63'C
