1090T on it's way out (dieing ? )

chaotic_uk · 12 Oct 2011 at 23:49

i have been running my 1090T for months at 3.9Ghz then a few days ago it kept blue screening , i dropped it to 3.6Ghz @1.39-1.4v and it was runing fine until today as it blue screened again so dropped it to stock .also updated to the new bios that was released today , my specs are in the link in my sig so what should i do as it seem to run my crossfired 6970's better when overclocked

What volts were you running it on 3.9? And if they were comfotably with the safe limits then strip i down and rebuild?

chaotic_uk · 13 Oct 2011 at 00:30

tried it at 1.375v but unstable so tried 1.425v which seemed stable for months , ran prime95 stable for over 4 hours

wentalong · 13 Oct 2011 at 06:19

hmm, well the max saffe is 1.55 so your alright on that front, what cooler and temps it would run at?

It would be worthwile checkimg the 12v power connector..
The 4/8 pin socket.

Sometimes the connections can start to burn and erode.
Causing the issue you describe.

id check heatsink monitor temps.

chaotic_uk · 13 Oct 2011 at 13:52

the cooler i use is the BeQuiet Dark Rock Pro , max temps in prime is 48-50c

chaotic_uk · 14 Oct 2011 at 19:17

got it running at 4ghz @1.46v but the temp hits 59c in prime 95 , is this something i should worry about ? (see sig for more detail)

You do have a bit of drop on the 12V line, like pcz says check the psu cable and maybe try another psu if you have one to hand.

Did you add anything else to your rig just before it started to become unstable ?

no nothing has changed

software cant reliably test voltages from what i understand and you can expect a small range of change in the 12v line and also the max temp for the 1090t is 62C from what i can understand so you might wanna be carefull, i suggest stripping it down to a skeleton rig and re-applying the TPU, what TPU are you using aswell?

all your North and Southbridge temps seem fine so it could be the 12v line however im not too sure, i think you should strip it to a skeleton rig and then report back from there,

re-applied the Tim last week which is mx4 , only in prime95 it reaches those temps .
while gaming it is about 44c while playing rage + dirt3 and crysis2

edit : just lowered the voltage to 1.45 and the max temp is now 54c instead of 59c

Well is it still in warranty? I would assume it is.

yes but it was purchased locally and not from ocuk , they are known for being good at rma's . buying a new cpu next month anyways (early xmas present)

Well even if it died past your retailers rma period you still have amd to rma back to and they where great with my 965.

Another 965 yes.

chaotic_uk · 17 Oct 2011 at 01:40

well it has started stuttering in games tonight , nothing has been change since i clocked it to 4ghz . temps while gaming never go above 45c so something in not right

Are you sure its not a motherboard or PSU problem??
