X2 550 Unlocking & Overclocking Consolidated

[Rezag1000]

On a mugen 2 (applied with ocz freeze) with stock fan, I run my x2 550 at 4ghz with 1.505v and the under load it goes up to about 48 degrees. When I unlock it and run about 1.4v it is close to the same temperature.

On an unrelated note, does anyone notice these cpus have a weak IMC, or did I just get an unlucky one? It won't run 1600mhz no matter what I try, even as dual or quad.

How do you read your temps once you unlock it? On my 790X UD4P, unlocking my 550 renders the temp sensor inoperative. I suppose this may not be the case with all boards though.....

Another question. Shouldn't unlocking two additional cores add a considerable amount more heat? I find it suspect that the temp remains the same.

BTW, how do you like the mugen 2? I am thinking about picking one up!


EDIT: I just read the part where you say you run 1.4V when unlocked. sorry! That makes more sense now. thanks for the info!

1600MHz? or 2600MHz? What memory timings?

1600mhz memory. The OCZ kit rated 1.65v 7-7-7-24. I can get it to pass memtest but prime95 blend fails instantly with either 2 or 4 core. Therefore I blame CPU IMC.

I use the newest version of Everest, it displays the overall temp but not each core individually (which I think is unimportant anyway). If I'm not mistaken doesn't the LED readout on the MSI board display CPU temperature too?? edit: forgot this wasn't GD70 thread lol But anyway, yes the heat produced will go up a bit when you unlock from dual to quad. Like the x2 550 is 80w while the x4 955 is 125w so temps will go up some. And I love my mugen 2. It is such a great heatsink. I'm running on stock fan and temps are stellar. I'm thinking about buying a San Ace or two and pumping even more volts

Wow if that is stable

Crazy memory and nb speed along with such a high clock and low voltage

It's a fine board, and liked this OCZ 1800 6GB kit, didn't had so much fun with the 1333 4GB kit, needed 7-7-7 just to boot at 1333.

I'm getting "HT flood" error often, even with the 955's, voltage doesn't seam to cure the problem. Appart from that, have a very nice bios.
I'm happy till the next one, lol.

Hi

No, not Prime stable at that clock, I got an "HT flood..." error often.

[Daveburt714]

aGeoM: Sheez!! Some Amazing stuff showing up on here tonight!
Gartz aGeoM!...

It looks like you have some killer Ram, when you get around to running some benchies I'd love to see some comparisons using those high clocks with nice timings, compared to some 1600 clocks with the timings tighted....

I'm not sure if it would be possible (although it looks like it might), I'd love to see some benchies @ 1600 CL6....

I have a decent unlocked 550 that can hit those clocks, but not under 1.55v...

Damn, my hopes for the 965's just keep getting higher...

[aGeoM]

Well... I'd clock down to 3887, kept all the settings at the same,and run IntelBurn standart test.



sorry guys I just realise I lost the unleashed mode, gonna reboot and try again.

Edit: Ok, I can't run IntelBurn test or Prime without an "HT sync flood error", so I did SuperPI 32M

Make shure the HT has enuff volts..Asus love to have alittle more than stock on the SB and NBchipset.

Your Above 300HTT which isnt that bad but Im pretty shure with the HT@2700 its fubaring . Remeber Too High AMD HT even with DDR3 can cause flood problems. 5200 is the Max no matter what on any Mobo. The HTchipset cant take much over that with out big volts.

This error is almost always seen when the HTT or HT is past its operating freqency.. More so when HT exceeds 2700mhz .You wan to keep it below 2700 when ever possiable mmno matter the GHZ on CPU or NBmhz.

tweak for Lower HT bro

Have a great day,,

Bring it more performances to set a higher HT Link ???

Thanks for the advise, but I'm not sure if it's OC related or some bios bug on unleashed mode, this error happens even with low HT speed, 1200, 1400, ... with X2's or X4's.

Not much time ATM to debug, but I will try diferent bios and I have here an 720BE that I can compare with the DFI M3H5 results.

All the best.

Edit: 3Dmark06 run with an 4850 @stock, HT @16xx

Hi, I had a very simillar problem with a set of G.skill ddr3-1600 C8 1.65v.
Couldn't run them at their rated speed. Setting the ram to Auto in the bios was fine but it was setting them at 1333 C9 1.6v.

It took a while to figure out the problem. Then I got a hint while trying to force the voltage to 1.65. Apparently, Gigabyte tought it funny to confuse us with the supplied voltage to ram. On the 1.5v rating, it actually set the ram to 1.6v. Innitially, I manually set the bios to supply 1.65v. It actually crashed the ram even faster. Then I realized that setting the ram voltage to 1.65v in bios actually made the board supply 1.76v to the ram, effectively overvolting it !!/$"/%?

I had to guess the number to set in bios so that the board would phisically supply 1.65 volt to the ram. Since then, those sticks have been rock solid at their rated speed in both memtest86 and Prime95 blend.

I'm on latest bios besides. Still confused how they implemented the ram voltage on these boards....

[Maregg]

could anyone post the temps that they are getting with their dual core 550 and what HSF they are using?

I'm using the Xigmatek HDT-S1283 with artic colling TIM.
Unlocked X2 to X4 with a modest overclock. My room temp is tipically 24C.
With that setup, I'm getting 34C idle temp and 46C load.

Oh I have lapped my HDT before sitting it up. Also, I have pretty strong airflow in my case.

So now you are running at 1600mhz stable? No matter what I do, I can't achieve 7 CL @ 1600mhz. Trust me, I've tried everything lol. It will pass memtest but fail prime95 blend. So the culprit is definitely the CPU IMC.

Hi

Well... I did some homework about my 550BE, and the unlocking cores. The CPU is... spectacular. The problem is the ASUS Crosshair bios and not the CPU. The Unleashed mode is crippled.

This was what I did:

ASUS CROSSHAIR III

- X2 at default speeds (HT/NB), and default voltages. Hard to unlock, needed n trials, never booted to windows.
- CPU default, voltages adjusted, hard to unlock, never booted to windows.
- CPU/NB at default, HT at 1600, left voltages changed, unlocked easy, booted to windows, couldn't run any stability programs, hard restart.
- Then I changed CPU, this time for an X3 720BE, same steps, except it booted with HT@2000, but no go for stability.

Now... I tested the X3 before with the DFI M3H5, with success, and was stable at 3200 with default voltages.


By ageom at 2009-08-05

I only needed to test the X2 on the DFI to be sure, and was what I did, CPU @ 3200, HT/NB@default, default voltages, MEM@1600 1.65v, the timings on the DFI are higher because the board refuse to boot @7CL, and voilà:

During the IntelBurn test


By ageom at 2009-08-05

IntelBurn test finished


By ageom at 2009-08-05


My conclusion, don't buy for now, an ASUS Crosshair III if you plan to unlock and OC your X2/X3 CPU's, the 402A bios for the DFI is a very good and stable bios to unlock the CPUs, I really hope (not just for me, because I sold the DFI with the 955BE) DFI updates this bios to a more recent one, bios 706 was a great memory speed improvement, but no unlocking mode.

Be well...

A little 5 loop IntelBurn test, CPU@3800, HT/NB@2600, voltage detail on the SS.

The board undervolts a little under load, but still stable.

[Daveburt714]

FWIW aGeoM, I've had alot of the same problems getting DDR3 1600 stable on the GBT board....

If you feel like playing with it (I know you like to OC so you know you want too), drop your Mem divider to 1333 and push the HTRef clock a little...
You should be able to get the clocks close to 1500 while seriously tightening the timings..

From your earlier posts it looks like you have some Killer ram...
Run some benchies ~1500 @ 6-6-6-18 and you'll wonder why you ever even worried about 1600 clocks....

Edit: Here's a little example:

[aGeoM]

Hi Dave

Thanks for your suggestion, the above posts was not an OC result, but just to proof the stability of the unlocked CPU, is more related with board/bios than the CPU it self.

I delivered the DFI board a couple hours ago, I build a nice PC to a friend of my oldest son, together with the board the 955BE and the 4870X2, and 4GB OCZ Reaper 1333.

Unfortunately I'm already missing the board, all the CPUs I have are for unlocking, and now I don't have any good board for that, even the DFI M2RSH that I have doesn't unlock as the M3H5, so my only hope, before a buy a new M3H5, is waiting for an good bios for the boards I have.

And by the way, the memory I have are not the killer memory, they are rated to 1800, the Crosshair III have good memory programming bios, better than the DFI. That's why I could run it as you see on my posts.

Be well...

[NoM$_YesLinux]

Anyone has tried to use DFI LP JR 790GX-M2RS with bios R7JD422 to unlock cores?
I got a X2 550BE 0922CPMW, but ACC AUTO does nothing...

Any suggestions?

Sorry my bad english, thx for help!

[Dilla87]

ok well i plan on buying this from newegg to unlock the extra cores and save a 100$. first has anyone tried unlocking with this mobo? ASRock A790GMH
i plan on using this setup
AMD Phenom II X2 550 Black Edition Callisto 3.1GHz
CORSAIR CMPSU-400CX 400W ATX12V V2.2 80 PLUS Certified
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)

would everything run smoothly and wats teh best mobo to use for unlocking the extra cores. like wat has the highest percentage of working

[uhhhevan]

I'm newer to overclocking and unlocking. i have a gigabyte MA790x-UD4P mobo, i unlocked my 550 but when i boot into windows some of the screen goes pixelated for a brief moment. The windows 7 splash screen also gets weird and i cant run Prime 95, it just crashes. so does this mean defective? change voltages around? sorry but like i said I'm a noob to this stuff.

help would be much appreciated =]

[Valg]

Stepping- Voltage - Frequency - Username - Mobo model - Bios used
0925APMW- 1.35V - 3.4Ghz - Valg - Asrock A780GXH/128M - P1.0, P1.10 and P1.20

MAX OC: 3.6Ghz @ B50 4 cores
3rd core is not stable over 3.5Ghz, so i keep it on 3.4Ghz all the time.
I can OC in the AMD AOD ACC to 3.8Ghz all cores without the 3rd and 4th.
But i dont push it.
Im just happy i got 4 cores, and maybe i change my 550BE for one 550BE that runs 4x4Ghz,
and some cash.

CPUvcore Should read 1.35volts (Stock)some CPU's may need more though at stock if they are buggy X4cores.

UD4P/UD5P DDR2/DDR3
X3 720BE/X2 550BE ,,
Hybrid Mode is set on AUTO .
Set the (NBvid to .+100 )for Stock use Up to 3400mhz @X2@X3@X4cores...
ADD more NBvid when you Overclock past 3400mmz @X2@X3@X4cores...
Usually +.200 for above 3600mhz with 2400nb.

This should make it stable .. If its not,, check your ram timing and ram voltage.

Not all 550 unlock successfully...
Usually NBvid may just be a hair too low. Thus unstable in X4mode @ default voltage..So by raising that value some it usually will make a weak IMC(NB) stable.

The Higher you try to Go usually the More you may need volts to about 1.25v if you are not going to raise the NB past stock when Overclcoking to say 3600mhz .

[soliqas]

Can anyone suggest good overclocking ram (DDR2 1066) to go along with a gigabyte GA-MA790X-UD4P? I am currently using these (http://www.newegg.com/Product/Produc...82E16820231166) but I can't push the FSB past 206.

[Gu!ll3rm0x]

And the ECS A790GXM-AD3??? is possible unlock a phenom II 550?
