help for 1090T

post #1 of 19
Thread Starter 
Hi,

Ive been reading posts here for quite a while. So now i thought about overclocking myself to ^^
So i have started with experimenting and i just cant get a stable 4.2Ghz OC.
this is my first time overclocking anything so i was wondering if some could help me out?

My current settings:


Ive had all the cpu voltages from 1.450 till 1.475, And this is the most stable i can get.. I can boot windows (it is something >><) but every time when i run prime i get the nice shiney black screen >.<

So some please help me with this?

Well, two things really. You should up your vcore for stability in this case. Also, you may want to dial back your HT link as far as multiplier is concerned. Also, you should get some positive results with something like 212 FSB and 20.0x. Some of these Phenoms dont do well over 20.0x multiplier. I have phase change cooled the same chip with a stable speed of 4.9GHz and vcore 1.8125. Temps were -28C under load and -33C idle. It was a thing of beauty. Still use that chip and love it. You can really push that thing. Your max voltage is about 1.55V vcore under WC 1.6V if you disable the boards limitation for overvoltage... usually a jumper on ASUS motherboards. And Prime... even though it is a good tool... often gives you the best idea of stability issues. I think you are safe upping your vcore.

I would try 1.5v on the cpu, if it doesn't work you have hit the wall.

Ill try that this afternoon, Ill keep you updated !
post #5 of 19
cpu/nb voltage to 1.3v

nb freq to 2600mhz (13x)

200x21 1.5v

turn off cnq/c1e

core temps on x6's are off by ~10c .. use hwmonitor to check cpu socket temps instead, and keep that below ~55c

I have tried all of it (vcore 1.5 cpu nb 1.4, 13 the freq @NB freq)
But i dont understand 2 things
1: How can i turn of cnq/c1e (and what is it?)
2: How do i calculate the HT link?

I have also tried updating my mobo, Dint help eigther >.<

ANy more suggestions?

EDIT: I've got it stable @3.7 Ghz now, Still running prime, ill know if it is stable in 1-2 hours

1. C&Q is located under Advanced Tab, CPU configuration in bios.
2. HT Link Speed usually has a multiplier , check your mobo manual it's easy.
Id have to suggest raising the NB Freq to 2800-3000MHz to run a 4.2GHz, and lastly, there's been no mention of what speed your ram is currently running at. That may be your problem. Remember when you raise the Ref Clock Freq it changes the ram freq too (as well as the rest). Maybe you need to look at that, as well as ram voltage. For starters try to maintain HT Link Speed as close as possible to 2000 MHz, raise the NB Freq to 2800, and keep the ram as close as possible to stock freq. After you get that stabilized than OC the ram by it self, makes it a lot more simple to know what's giving you trouble when it gets unstable again. Just in case you haven't seen it, here's a good thread to give you some good understanding of how to do things http://www.overclock.net/amd-general...ing-guide.html
At least after reading/understanding this much you'll get a lot further, much easier, plus have a path to follow rather than just throwing things at your OC and wondering why it doesn't work! Hope this will help! Good luck!!!

Can there be a change that my psu is acting up?
Cause my 3.7 works perfectly fine and when i speed it up a bit more i get that black screen. My psu is the only thing i haven't replaced yet (470W stock psu of a HP Elite)

and i rode the tut for a bit (half way) Ill read the rest tomorrow ^_^, Keeps you off the streets

And about my ram, i keep making it get as close as possible to the stock 1333Mhz same for the voltage Most of the time i chose the lowest option? (Helpfull or useless?)

HP PSU most definitely could be part of the problem! OC'ing requires a quality unit to hold steady voltages. I wouldn't do any thing more till that HP PSU is gone lol. Sorry man you can't get quality from OEM components. You may even do damage by using it! Do yourself a huge favor and get some thing coming asap. Why risk your whole investment on a less than adequate power supply? It IS the heart of your system!

LOL @ 470w HP PSU

This thing will vdroop the heck out of you...just think of voltages constantly dropping. Buy a quality PSU then we'll see why your overclock isn't working.
