Overclocking my 1090T

Hey everyone !

I just started to overclock my 1090t ... with the goal of getting a better and SAFE clock speed of around 3.7 or 3.8

I started to increase the fsb slowly to get 3.6 was barely stable at stock Cpu voltage , 3.7 was Instant BSOD when trying to start prime.

Soo here i am , i raised the cpu voltage from 1.32 to 1.38 ... Still BSOD ... Raised 1.38 to 1.42 ... Still BSOD ... Finaly Raise 1.42 to 1.45 and it Work perfectly at the moment , been 1 hours on prime95 , getting 55C stable on full prime load ...

Im wondering , i've set 1.45 as CPU Voltage , but VCORE says 1.35 , i tough it was the same !?!?!

What do you guys think about that ? should i stay like this , lower or raise FSB , Multiplier. Is it Safe or not ?!? Many question in my head right now. Every opinion or warning is welcome

overclocking from windows using software is not succesful your better off if you enter bios on start up and change the settings there what you have set is good and should work and what you could do is up the NB frequency higher too it will increase performance

im Doing it from bios too ,windows was just to the picture.
Ok , I'll try the NB ! and do some research about it

Picture quality is OK, just needs one more click to increase the size.

Well for monitoring id try use hwmonitor im not sure of how accurate asus software is, that been said i can't say its wrong either
You should check out this thread its got good info on stable overclocks in it

You can safely put 1.5v to your cpu just monitor the core temp, you probably already know too to disable cool n'quiet and turbo core

I don't understand why you are upping the FSB.

Doesn't the 1090t have an unlocked multiplier?

While true the multiplier is unlocked the phenom processor can tend to overclock more stable on the bus

I would try the multi first, because FSB overclocking (Like I did with my 1045t) messes with everything.

I can understand trying the FSB for that extra little kick once you hit a wall with the multi, but starting with the FSB on an unlocked CPU just seems like doing things the hard way.

Actualy , am i wrong if i thing that it doesnt change much for a low % overclocking ?im happy as long as it stable and doesnt reduce my CPU life by 2000%

I overclocked my 1045t using the "FSB" because I had no other option.

It changes things in a hurry. Primarily the RAM. And unstable RAM is BSOD city.

I had to downclock the RAM and adjust the CAS timings to get her stable.

(From 2.7 to 3.4, with a turbo of 3.8)

Voltage and heat are what you need to keep in check for long life. My 1045t only needed 1.344v for 3.4Ghz. From there it required loads of voltage for small increases in clock speed, so I left it at 3.4.

I could be wrong but from any testing I've done I always found using a lower multiplier more stable i run my 1090t stable 24/7 using 300x13 for 3.9ghz
I agree with what your saying Z1NONLY to use this method you need to work on your ram and know what will work for it

Soo if i understand right ! It was a good thing to overclock with my FSB since my ram is Oem 1866 But was only detected as 1600 MAX.

Correct me if im wrong
If i would have overclock with multiplier only , my result would have been 3.7 ghz on 1600mhz Ram

But since i've overclock with FSB , i Get the result of 3.7 ghz on 1800mhz ram.

with 1800mhz i'm almost using 100% of my Ram oem specs.

well with my 1090t i found the best way to over clock it was a combination .. set the multiplier to 18x then oc the front side bus depending on the type of ram you have you may want to drop the speed settings down to 1333mhz and go from there saying you have 1600 mhz ram .. if you have 1333 then drop down to 1066 and then bump the fsb up until you reach 1333 or equivalent.. i have gotten my 1090t to 4ghz using this method and with the same 1.45 voltage the issue is heat .. though because at that point your temps are pushing the limits
1.475 and i wouldnt go past that.. just fyi

You have a different multiplier for the RAM if you want to increase the speed there.

When overclocking, it's best to take one step at a time. That way when you get a BSOD, you know why it happened. Changing multiple things at once creates a lot of suspects when you have a BSOD.

In fact, I suspect your RAM is causeing the BSOD.

When RAM is "detected" at a different speed than advertised, it's often at tighter-than-advertised CAS settings. If you just increased the speed of the RAM without changing CAS timings to their advertised specs, it's probably unstable and causing crashes.

I would go back to stock, leave the RAM as detected, get a good overclock on your CPU using the multi, (adjust vcore as needed and keep it below 55C if you can). Then after you have the CPU nailed down, go back and work on your RAM.

to keep it at 4 GHZ i would say you would need either a really good heat sink possibly a coolermaster hyper 212 or an h100i or the new h110 liquid cooling kit. or you could set up a custom loop

yea the 1090t dose not really want to run stable past 1600 mhz even with 1888mhz ram.. depends on the motherboard your using but i would say drop it down lower and try to keep the ram within 1600mhz it will keep your system from bsod really.. ideal would be down to 1333 and then bump it up from there then work with the timings on the ram it self that will negate some of the lost speed .

another thing i found is that if you have something like a revo drive in your system populating a pci express slot any kind of bus / multi adjustment will make the system unstable and bsod. only work around for this was to oc via fsb but if you went past the rams rated speed it would not post.
