I just dropped an eBay 4400+ X2 in my 939 machine in the rig in my sig.

I forget the stepping, but it was manufactured the 38th week of 2005, I believe. (0538?) Also this processor is the ADA Toledo core (110w TDP versus 89w TDP, I believe)

It's stable but it seems to be getting too hot.

Settings:
Multi: 10.5
HTT: 248
CPU: 2605MHz
RAM: 201MHz (402MHz effective)
Voltage: 1.45 (actual is 1.46-1.49)


I chose 1.45v because Windows would not finish loading with 1.425 or 1.400.


Anyways, BIOS idles around 32C, as does Windows. Matter of a fact -- it's showing 28C right now.

As soon as I start Orthos (5 seconds later?) the CPU temp JUMPS to 55-65C and CoreTemp shows the same thing. How can a processor idle below 30C and 5 seconds under load causes the temp to double?

I applied the processor with a THIN COAT of AS5 all over the IHS. By thin coat I mean I dropped two drops of AS5 in the middle and kept spreading until the entire processor was covered with a thin coat.


What's going on here? BTW my case has 2 120mm fans and all my wires are neatly tucked and hidden.
 
Also under full load one of the cores is about 6-10C higher than the other core.

This DOES NOT HAPPEN at idle.



And yes, my heatsink is properly attached. I gave it a good tug and it's not moving. It's locked in on both sides.
 
OOPS! hehe

I'm using the Stock AMD FX/X2 heatsink. Copper core with 4 heatpipes.

Model: Coolermaster CMHK8


Right now I'm back at 2200MHz, stock voltage. I'm reading 44C on Core0 and 50C on Core1. Is there suppose to be such a gap between cores?
 
That truley is a wierd problem, what program are you using the monitor your temps in windows? What BIOS do you have? Did you update your BIOS recently?
 
BIOS is at the latest version.

I've been Priming at stock clocks for 1.5 hours now and:

Core0: 45C
Core1: 50C


The SECOND I hit STOP on Orthos my core temp dropped 15 degrees C. I'm talking the INSTANT I hit STOP.

Two or three seconds after hitting START I'm already at the "full load temperature" of around 50C.


To monitor temperatures I'm using CoreTemp along with SpeedFan.

Currently it's idling at 27C which is WAY LOWER than my 3400+ Venice used to get...
 
I'm currently Orthosing at 1.4v, 240x10 (2400MHz, memory 200MHz/DDR400, HTT 4x)


I'm at 48C on Core0 and 55C on Core1. This is with a modest +200MHz +0.5v bump.


The heatsink doesn't even feel hot. I know I didn't install it incorrectly because my BIOS/Windows idle temps are pretty low. BIOS is calling the shots around 32C and Windows (CoreTemp) is reporting 27-30C idle.

If I had incorrectly installed the heatsink I'd be idling at like 50C LOL.


What's the damn deal here? The CPU is WAYYYY OLD. Were they even making X2s in Week 38 2005? I wish I had written down the stepping code but alas I didn't.


Oh, I bought this processor on eBay along with a free shrink wrapped copy of BF 2142 for $170 shipped. Newegg wanted $211 for the CPU alone, OEM not retail.
 
A 15C difference isnt really THAT unusual...I'm not an expert on X2 processors, but what I know is about my processor and it loads 10C higher than it idles and it happens instantaniously as well when I stop running prime95.

I know you said you applied the paste thinely and all that, but you may try re-seating the processor yet again using different methods to apply the paste each time. Record the temps with each time and see what works best and use that method. Personally, I like to use the method you used with a very small bead in the center of the die for good measure to make sure that any uneveness is taken care of, the other method I have used is the small dab in the middle and twisting the heatsink a little like is recommended on the AC website. Both methods worked well, but I'm thinking that you may have a gap between your processor and HS base, you may try the rice grain size dab in the middle and twist method to see if that yields better temps. Also, remember, if you screw the HS down, do so with even pressure (I.E. don't screw one side down all the way then the other. Screw one side down half way then the other half way and continue to go about a half or full twist more switching from side to side. Thats what I do with my zalman to ensure that the pressure is equal on both sides when the HS is applied.)
 
I've got another AMD 4-pipe heatsink here with the thermal pad still attached. It's more AS5-y than it is thermal pad, actually. If I touched it it would grease off onto my finger, I'm sure.

I just don't see how between full load and idle the difference (at least at 1.4v/2400MHz) is a whopping 25-30C. My Venice idled at 32C and loaded at less than 45C (stock clocks, though)



So you're saying I oughta:

1. Take heatsink off
2. Clean heatsink and processor
3. Put a DOT of AS5 in the middle of the CPU
4. Put the heatsink on and twist it around for a couple of minutes to spread the AS5
5. Lock heatsink in place


BTW: My heatsink doesn't screw down, it's a factory AMD unit that has the black tab you lock in place.

I've also been told the Freezer 64 Pro (Artic Cooling) doesn't cool any better than the stock AMD 4-pipe heatsink. What do you know on that issue? I'll change coolers if I have to because my goal is 2600MHz.


Could it be because I have an old processor? This processor shipped in the black AMD boxes that people got at trade shows and the AMD Tech Tour thingie a couple of years back. The seller said the processor I got (4400+) wasn't the original processor in the black box and that an AMD employee gave her the box.

I swear the week code was 3805 or 0538, 38th week of 2005??
 
My Opteron 165 is the same way. I idle at about 28-30 but under load I reach a max temp of about 60. I even see the same difference between cores that you do. My core 1 is usually about 5-7 degrees hotter than core 0. Like you, I'm running at 1.45 v. I'm cooling mine with a fairly highend heatsink (Ninja) and it happens so it's not all that surprising that you are seeing it with the stock hsf.
 
Since I last posted I've:

- Removed the 4 pipe heatsink, cleaned the processor and installed a SEPERATE 4 pipe heatsink with the OEM Thermal Pad still attached (obviously no artic silver on the proc)


What I've discovered

- When I load up Core0 the temp doesn't hardly rise. This was accomplished by setting the affinity for Orthos to Core0 only.

- When I load up Core1 the temps rise moderately.

- When I load up both cores there's a shitstorm and the cores full load at 45/50C, this is at stock 2200MHz and stock 1.35v

- When I play a game (Quake4 for example) the temps don't even crack 40. I believe SpeedFan reports the hottest core because when I look at both CoreTemp and SpeedFan, SpeedFan reports the hottest core.



Is my processor ok? It's completely stable at stock speeds (which it should be) but it gets awfully warm -- IN ORTHOS. Not in games.
 
I'm thinking there is something going on between the cores or with your program.

I've heard that there is a way to install prime95 to run on two cores. You might want to try that...if you can load 1 core at a time and it rises only moderately, then im thinking its something other than the processor or cooling. I'm thinking orthos may be at fault...or that your processor or motherboard is producing temps incorrectly when both cores are at load...someone with more experience with dual cores than me might have a better suggestion then I however.
 
When I took off HSF earlier I wrote down the stepping and everything on the CPU

ADA4400DAA6CD
CCBWE 0538XPMW
1335057J50405



Is 0538 the manufacture year/week, because if so this is quite an old processor for an X2, is it not? 38th week is the 3rd week of September 2005.


SpeedFan is reporting my case temp to be 50C. There's no way this is possible. I have built three computers using the same case and case fans. I've got 1x120mm front and 1x120mm rear along with the 120mm in my PSU. I know this is not possible because with my Venice processor installed it rarely peaked 40C under load. My hard drive is a chilly 37C currently. In addition, my house is kept at 68F.



I am using the Orthos that stresses both cores at once. If I wish to single out one core I simply set the processor affinity in the task manager -- works perfect.

There is no indication that this processor has previously seen watercooling. No scratches, scuffs. Infact there was a little white grease/TIM left over on the side of the processor that people rarely clean. I have no reason to believe this processor was ever abused physically. The seller was actually a GIRL, so take that for what it's worth :D (Not saying girls can't watercool/overclock, just saying it's probably 80% male Tim Taylor MOAR POWAR types)


I also ordered an Artic Freezer 64, a 92mm case fan to replace the CPU shroud that will directly bork my Freezer and I ordered some new AS5.

The newegg reviews said the stock paste on the 64 is MX-5 and I should use it instead of AS5 -- fact or myth?
 
Bad news.

Shortly after I typed the above message the computer hardlocked. It's NEVER NOT ONCE hardlocked. This was during an Orthos session at 2200MHz/1.35v (stock/stock)

So... I reinstalled my Venice. Orthos doesn't bring CPU temp above 40C. That means that I know how to install my heatsink and spread my AS5. LOL.

What to do now?
