X2 550 Unlocking & Overclocking Consolidated

[xixo_12]

0922CPMW - xixo_12 - Biostar TA790GX3 A2+ - Mod Bios (RH) - Success

Too hot to handle by Stock cooler

[Seth-01]

what about that

good translation !

sorry for the french spoken

edit : i made my choice : i'll buy the gigabyte !

at the moment my X2 550BE 0919 EMPW and my X3 720BE 0904 DPMW won't unlock on my ASUS M4A78-E. If I enable the ACC, the motherboard reboot and don't post

Yet to see anyone unlocking on the ASUS M4A78 - so probably BIOS issue?

[dexx]

Has anyone had success with the Gigabyte GA-MA78GM-US2H? The Rev 2.0 is supposed to have sb710. But i dont know if the bios is capable.

[Chrono Detector]

Here is my overclock, its not stable I didn't even touch the voltages and I was able to boot into Windows with the magical 4Ghz all on air.



For some reason I cannot set the multiplier higher than 19. Must be my motherboard I suppose. I tried unlocking the 2 other cores but it doesn't work, it either won't post or I cannot go past the boot screen. But whatever, I don't really care.

sooo it was a fail

what was the mobo & the date?

My 720/550 do the same thing on my M3A79-T with Modded Bios and wont even work with any stock Bios by ASUS.


My UD4P Unlocks both flawless with STOCK BIOS F5....


Id say the Mobo has to do alot with what works and what dosnt... Gigabyte has the best success so far .Even there low line UD3 unlocked both of mine too when tested for a friend while he waits for a new 550.

[KayDat]

I have a 790Gp-UD4H, and while I still haven't gotten around to doing some solid OC'ing, it's a nice board. =]

I finally went and took off my heatsink the other day to take a look, and guess what I found?




It's a 0920GPMW! Boy do I feel lucky. I'm only the second person to have a 0920GPMW to successfully unlock.

[zelos]

sorry for the french parenthese

by the wat C-buzz you didn't correct the mistake about the stepping on the 1st page

[Chrono Detector]

Don't see any pics Chrono

The screenshot is on my post, you can't see it?

I only wanted to see if I can successfully boot into Windows without touching the voltages and I was surprised to see it did. It was "stable" until I ran IBT, though I knew it was going to fail but I wanted to see how long it would last. I will increase the voltages later.

My motherboard is a Gigabyte GA-M720-UD3, some budget board that cost me like $98, and I just overclocked this yesterday.

Well, then i´m the third one here

0920GPMW - DonBanana - ASRock A780GMH/128M - P 1.20 - Success



It´s hard to overclock on that board because of the voltage instabilities

i think so ! i will see later, my gigabyte is on the road ! this week i will try to unlock the 720BE and the 550BE.

0922APMW - successfully unlocked to 4 cores stable, Biostar 790GX XE
0923APMW - successfully unlocked to 4 cores but only 3 cores stable, Biostar 790GX XE

I wonder how many of those who failed to get 4 cores stable have tried running their chip as a tri-core ie. x3, it's plenty fast still.

My early UVOC attempts, not finalisd results cos yet to fully tweak the NB speeds.

its kinda funny that since its only a tri core CPU-Z is still picking it up as a Quad.


Anyone have any good ideas on getting good CPU Temp readings after unlocking.

[MacClipper]

To the BIOS, once unlocked it is ID-ed as a quad with a disabled core - x3 when running as reported by CPU-Z.

For my 790GX XE mobo, the onboard sensor seems pretty close enough to the onchip sensor,

great ! it's the first time i see this ! Phenom2 X2 550 no running as a quad core but like a 3 core

Check the Bios version you are using ,, I recomend the Most recent from Gigabyte for UD3 and UD5..Check the Default CPUvcor as it should be 1.35v NOT 1.3v or 1.26v..Disable CnQ too or you may have problems with Default volts when enabling X4cores.

UD4P the F5 is best for unlocking X2 550 ATM.

Make shure to Set the ACC mode to Hybrid and use the Auto ACC function ..Also set to stock Multis when you do this for the first time so it will enable all cores .. The UD3 does unlock them in Hybrid Mode under ACC setting for Firmware(Auto ACC suggested).

Note :
AS for The X2 550 being a 3core that means usually you have a Downcore option enabled or are not using ACC auto with Hybrid and could be using a older outdated Bios.Check to make shure you are using Most recent Bios. You should also make shure the NBvid is set to +100 for fourcores to help the IMC..

This will set the NBvid to 1.2volts instead of default 1.1v which is way to low. When overclocking fourcores @ 3400+ and stock volts on CPUvcore or VID.

Here are some screens all with my Mobos Default of 1.35cpvid(default volts) and NBvid @ 1.2v not 1.1v..this should be set for UD3/ Ud4 /UD5mobos regardless of DDR2/DDR3 as i have tested this for a friends setup as well.


NBvid is 1.1volts i found this to be too low when i went to 3500mhz and only 2200nb


NBvid @ 1.2volts with Stock Vcore or CPUvid


NBvid @ 1.2volts with Stock Vcore or CPUvid


NBvid @ 1.3volts with (CPUvid set to 1.45volts)


I recomend 1.2 NBvid as the lowest to run when in foucore Mode and even as an X2core. I found that @ 1.1nbvid it would be unstable past 3550mhz unless i used 1.2volts on the NBvid..

Note: all runs are with the NB set to 2200mhz @ above CPUvid's in screenshots...It is very consistant volt wise in X4 and X2 mode .

Im using Water,,
Air you may need slightly more CpuVcore and or NBvid for same results...Bump the volts slowly since these Cpu's dont need Xtreme volts ,Unless your going supercooled keep the Volts minamal @ 1.2NBvid for under 2400mhz NB or More for Higher NBmhz. It works the same for UD3/UD4/UD5 ... Its simply what the CPU wants...Default voltages are only good up to 3500mhz on average for X2 550's ATM with Air or Water.

Have fun ,,

My 0924FPMW on my Asus M3A79-T deluxe Bios 0803, 0905 FAIL

to unlock 4 cores, but 2 running easily 3.7 ghz on air flawless

[Snowman89]

Im thinking of getting a 0918BPMW, handpicked from the shop. It seems like a good cpu for unlocking or?

Well I was able to unlock mine. YMMV though!

testing a 0922 CPWM with Gigabyte 770T-UD3P yields the result :

Hello AMD boys

good news but at first the story of my Phenom 2 X2 550 0919 EPMW :

Motherboard : ASUS M4A78-E DDR2 790GX & SB750

Original bios : 0711 ..... unlocking : failed (black screen and reboot again, again and again .... when ACC is enable)

Bios 0082 modded : unlocking failed (when ACC is enabled, it's the same like 0711)

other try with bios from ASUS give me the same results : no boot

Bios 1204 : unlocking failed (when ACC is enabled, it's the same thing like 0711)

last try : bios 1210 (the last on line), I put the multiplier on 10, raise the vcore @ 1.50v but decrease the HTLink to 1600 MHz). I enable the "special" "unleashingé mode with ACC and try a boot.

Hmmmmm the PC boot but i have not see the post. Arrived under Vista, a little CTRL + ALT + DEL and i see ........... 4 active cores

A big YES !!!! I'm not sure : it's the last bios or the HT Link set to 1600 MHz but there are now 4 active cores.

I try 3200 MHz with 1.50v and it's stable. Maybe i can decrease the vcore but i'am now interresting to overclock my new quad core that cost me 85 €uro!

Sorry for possible mistakes, my english is a little poor

wow!!so high vcore!! carefull as that is the max vcore. 72degree i thinks max temp for x2 550. try to lower 1.4 for daily use as i can get 1.15vcore x2 3100mhz. x4 3400mhz for 1.35vcore
