X2 550 Unlocking & Overclocking Consolidated

**mariol90** · 07-06-2009, 10:53 PM

I was going to post when there were 4 pages in this thread... I never got the activation email or w/e. haha. but it lets me post now, yay.

0919EPMW, with a GA-MA790XT-UD4P (both from newegg). had to flash the bios to F4 first.
stock HSF, thermal pad (i'm really lazy, and don't know where the AS is), runs in the low 40s C. I can bump it up to 3.6 GHz in windows without a problem using phenommsrtweaker, haven't tried prime95 or anything at that speed though. but it's been running 24/7 since I got it ~2 weeks ago at 3.2 GHz (1.6 when i'm not using it), so i'm assuming it's all good.

and this might be a dumb question, i think i've read an answer before too (which was no), does CnQ work when all the cores are unlocked? i don't mind having to manually change the speed, but it'd be easier if it did it on its own.

It does, but only when it's not overclocked (for me anyway). Once I overclock CnQ doesn't work for some reason...

I haven't actually gotten to the point where I'm worried about power usage with this settup yet mariol90.....

But turn off CNQ and check out this lil program. It has worked really well for me in the past, and gives you lots of options to tune your energy savings!

It's very easy to use and has actually worked better than CnQ from my experience...

Here are some results from my phenom 550:
The strange thing is that when I try to rise the voltage above 1,38 the CPU is losing stability. Why could that be?

It can pass this test on 4 cores, but if I try to run BLEND, it crashes in a few seconds. I ran 3dmark06, some games, everest cache and memory benchmarks with no issues. It might restart few times but only after few hours of work. I've replaced my 64bit. XP with 64bit. Vista, but it became very unstable even on 2 cores. Do I need to find another prime 95 vrsion, is there any difference in 32 and 64 bit versions, are there any other tools to be used?

I'm having a hard time determining if you are taking the piss or being serious

Successfully unlocked 550 on Biostar 790GX 128M with Bios Jan 09

**Maregg** · 07-07-2009, 04:43 PM

Hi,

I'm wondering what could have caused a jump on my X2 550 BE idle/load temps.

Yesterday, it was 31C idle / 47 load.
Today, it has jumped to 33C idle / 49! load.

NOTHING has changed from yesterday. Same bios config, case wasn't opened. Nothing. The case temps are actually colder then yesterday ! (room temps are 3degree C lower).

Could the HSF have somewhat moved ? Is there a "burn in" period for those chips ? Could air pockets have somewhat formed between the HSF and the thermal paste ? I used high quality thermal paste.

I am very upset with this change. Furthermore, when I put the CPU thru some Prime95 today, it actually produced an error dump file. No such thing yesterday !
Re seating the HSF would be a huge pain as I would have to disconnect every wires/remove the Mobo ...

**richierich** · 07-07-2009, 05:37 PM

All you guys with Biostar Mobos and the bug HT Link @ 1600MHz download the modified BIOS from RH here

**00Bishop** · 07-07-2009, 09:10 PM

does anybody know why my amd overdrive 3.0.2 says "failed to start" and thats it.. it worked flawlessly 3 days ago =(
im the administrator and it is driving me nuts... i need help

**lamby_splendid** · 07-08-2009, 12:02 AM

any one do unlocking with stock fan? at what speed?

because your CPU is getting too hot...on your current voltage CPU temp is 55 but on my CPU voltage 1.408 load temp is 48 degrees.what cpu cooler do you have?i have Big Typhoon VX

this what i will say is only for Vojislav:

Ja vas Srbe zbilja ne kuzim...zar vi bas morate svugdje stavljat sranja kao npr Svaki častan Srbin je Četnik ili slicno??i jos se nazvati Šešelj(Serbian war criminal-Šešelj),de budi pametan i makni to.

My 0924EPMW so close, yet so far...

It will not let me boot into windows, I can do the start of a fresh windows XP install but after the reboot stage it won't continue the setup, it just keeps rebooting.

I have tried every possible setting in the BIOS, tried every BIOS but no joy, I can only get into the BIOS.

**SnakePriest** · 07-08-2009, 05:29 AM

you cores are not stable mate...or you should disable Cool and Quiet

some guy had the same problem as yours, his cpu when unlocked only worked with xp sp1

so try that

Is there a trick to Nb clocks? I have seen quite a few 2.8Ghz on some average mobo's, but my mobo MA790FXT-UD5P doesn't even boot > 2.15Ghz

**SnakePriest** · 07-08-2009, 08:08 AM

my BIOSTAR 790GX 128M wont go above 2000....

can you get into safe mode?

What voltages are you using NB and Cpu-NB? Try giving both both 1.3v + or - a few notches especially the Cpu-NB. I usually run 1.28v NB and 1.3125v Cpu-NB

**bjt007** · 07-08-2009, 10:58 AM

0922APMW on Gigabyte 790X-UD4P with F5 bios - Success

4 hours on Prime95 @ 3.8Ghz - will post link shortly

Hey thanks

That actually worked a treat, booted straight up at 2.6ghz no problem

Cheers
