HELP - Stable System at 3.6 Ghz

[STLL]

Hello, first of all let me congratulate you for the precious material out there in the forum. Sure it's has made good things for the PEOPLE.

I'm new to overclock, and since i bought my new computer i wish to overclok it, and so i am attempting to reach a full stable 3.6 Ghz overclok and i'm counting on your help to do that. Below there my bios and system settings:

Now im running at 3 Ghz but i'd like to achive 3.6. With my current settings i manage to run prime for 3 hours.

Do you sugest any changes? what should i do next?

Thanks in advance

Re: HELP - Stable System at 3.6 Ghz

just try with 1.3---1.32v for qpi voltage everything else looks ok,try my oc settings in sig if you want just set bclk to 160 instead of 180,all voltages will be ok

Re: HELP - Stable System at 3.6 Ghz

Hello wazza300,

Thanks for the reply, i'll try your settings soon as i can and i'll keep you informed.

Thank you!

Re: HELP - Stable System at 3.6 Ghz

You do have ALL those advanced memory options you say you don't have, they are just on another page you have to click enter to get into.

What cooler are you using? Can you also give us a link to your memory

Re: HELP - Stable System at 3.6 Ghz

Hello again :)

finaly i had some time to test my system with your settings wazza300, but it went bad. First, on prime, i had a BSOD with the error 0x0000003B than i raised Vcore a litle bit and this time i have a 0x00000101 error. I raised my Vcore again but i was getting high temperatures :(.

Since my goal is to reach a stable 3.6 Ghz i made some tests and yesterday my computer was 6 hours on prime, blend test, without errors but i notest something weird, the first 3 hours the cpu was on full load, than i left home and when i came back it was on 86% load. Is this normal?

Anyway my settings right now are this :

Hello Lsdmeasap,

Yes i have that options lol, i dont know why i didnt see them, now i have them in auto. I have a Corsair Hydro H50 cooler. Here is a link to my memory OCZ DDR3 PC3-15000 Reaper CL9 Edition Low-Voltage Triple Channel OCZ Technology.

Thanks a lot for the help. For what i have seen i'm beeing helped by 2 experienced guys :).

Do you suggest any changes?


PS- Sorry about my english, it's a portuguenglish lol (i'm from Portugal).
Another thing i forgot to mention, while in BIOS i click Ctrl+F1 and some new things appeared like the spred spectrum wich i disable it. Is this ok?

[Lsdmeasap]

Re: HELP - Stable System at 3.6 Ghz

BSOD 101 means you need more vcore

Your English is fine, I didn't even know.

Spread Spectrum can be disabled if you want, here is some more info on what it is
Spread spectrum - Wikipedia, the free encyclopedia

Also tons of other answers on this here if you wanna read everyone else thoughts about it
CPU Spread Spectrum - Google Search

Your settings look ok to me, you might be able to use less QPI/Vtt at those speeds/timings.

Re: HELP - Stable System at 3.6 Ghz

you said your cpu was on 100% load then 86% load?? did you look in prime95 to see if any workers(cpu stress programs for each thread) had stopped? this will reduce load percentages if one or two had

Hello Lsdmeasap,

How much should i decrease QPI/Vtt, when do i know it's giving me problems?

What do you think about my temperatures?

Thanks!

Hello Wazza300,

Yes i did look to prime95 and all workers seemed fine, it's strange... When i get a chance i'll run prime again.

Do you suggest another thing to do?

Thank you.

Re: HELP - Stable System at 3.6 Ghz

run a blend test in prime 95,lower qpi one/two clicks a time n do a test it will fail pretty quick if its not enough

[Lsdmeasap]

Re: HELP - Stable System at 3.6 Ghz

When QPI/Vtt is too low you will get BSOD 0x00000124 then you know you set it too low and to raise it back up a few notches.

Re: HELP - Stable System at 3.6 Ghz

When QPI/Vtt is too low you will get BSOD 0x00000124 then you know you set it too low and to raise it back up a few notches.

Question... So if I don't get a BSOD 124 that pretty much says my QPI/Vtt is good...even if Prime fails? In short, If Prime 95 fails, should I look elswhere and not worry about QPI/Vtt?

Sorry, not good at this overclocking thing... yet.

Thanks

Re: HELP - Stable System at 3.6 Ghz

Hello!

I didn't forgot you people, it's just i've been away last days and i did not have the chance to try new settings.

I'll keep you informed.

Thanks

Yes, that is pretty much how you can think of it. If you have doubts though open easytune and up the QPI/Vtt ONLY and test and see if prime still fails, if it does even after several bumps up in QPI/Vtt than the issue is something else

[sygnus21]

Re: HELP - Stable System at 3.6 Ghz

Thanks. That helps a lot as I'm currently tweaking voltages to find a sweet spot between temps and stability.

Thanks.

Edit. One other thing... I notice that if I use the XMP profile for my memory modules, the timings, voltage, will be correctly set (8-8-8-24-1, 1.65v), but doing this also adjusts the QPI/Vtt to 1.35 volts! Why the voltage jump in QPI/Vtt???

BTW my system is OC to 3.5gig and I'm currently running my memory at 1600MHz, 8-8-8-20-1, 1.66v, QPI/Vtt at 1.2v instead of 1.35v, Core Volt at 1.118 and the system runs good, even in gaming (however Prime 95 fails after 2-3 hours so...???)

[Lsdmeasap]

Re: HELP - Stable System at 3.6 Ghz

That is one of the reasons I suggest against XMP, no way some pre-programmed settings can know what your CPU needs for QPI/Vtt voltage.

Set it yourself and tweak it until you find the sweet spot, some XMP programming depending on the memory have QPI/Vtt set to 1.6 even so 1.35 is about average.

1.2 at 1600Mhz may not be enough and that could be why prime is failing, try 1.28-1.35 and see how things go
