Yes, the SLBGE will work (X5590 @ D0 steppings).Would stepping SLBGE work with a nehalem mac? Also do I need to get 1333 ram? I currently have a 2,26.
-Thanks
Yes, the SLBGE will work (X5590 @ D0 steppings).
But the firmware is fixed at 1066MHz rather than follows the SPD timings when the memory controller could utilize the faster clocked RAM (1333MHz RAM will function, but downclock to 1066MHz). So your existing RAM will work. If you need more, go for cost/capacity (which ever is cheaper between 1066 and 1333 sticks/kits jto get you where you need to be).
SLBGE is the letter code used on the OEM and retail versions of the X5590 sold by Intel (only letter code that showed up on ark.intel.com; so no different steppings, ...). So they may be the same in this case.Hi, thanks for your reply. Would you happened to know how "reliable" these ES chips are? There is a seller from hong kong saying that this ES chips (SLBGE) are the same as final chips. What do you think?
-Thanks
Heat-spreaders are glued to the PCB and I wouldn't recommend trying to remove them. Many people destroyed their CPU's trying to remove the HS with razor blades.
A little safer approach is to sand the HS till you reach the DIE, but again, you have to be VERY careful because if you sand too much... well I don't have to explain it, do I?
Bad chip is likely (these get abused during testing, and may have been overheated and damaged the transistors on the die = not fully functional any longer).I purchased from bay 2x Intel Xeon E5345 Quad Core 2.33 GHz MATCHED PAIR CPU. They were Confidential Engineering Samples and one had the markings:
Intel Confidential
QWTW ES Costa Rica
imc '05 HH80563QJ0538M
3720A955 e4
The other had similar markings.
I used them to replace the original 2.66 GHz processors in my Mac Pro 1,1 (2006). Upon startup I got a "panic" the first line of which read:
panic (cpu B caller 0x295aab): "Should have 2 Cores, but only found 1 for Die 2"
@/SourceCache/xnu/xnu-1504.7.4/osfak / i386/cpu_threads.c:1118
After replacing my old cpu's my machine runs fine.
Any suggestions????
Please excuse me but I posted this two days ago on another thread but thought it might be ok to post in this thread also since someone here was asking about using ES chips in the Mac Pro.
Here.Can anyone provide me a guide on how replace the W5590 on the the Mac Pro 2009 Processor board. Since the original Mac Processor doesn't come with IHS and the normal Intel Xeon have the IHS so how much high do i need to justify so that i wont be over tighten the heatsink and damage the socket 1366 pins.
Here.
There's also another How-To somewhere in MR (look for a couple of users known as Tutor and gugucom).
Need help,
I've got all the part and assembly the Mac pro early 2009 I'm now facing the issue of no post. There is no indication CPU fan are spinning and no ram led light up. But just no post at all someone pls help.
Make sure the connector in the heat sink/fan is connected to the base. I think there is a problem where it doesnt reach and the motherboard thinks the cpu is dead and does not turn on. Read back on this thread.
P.S. What CPU did you buy and from where?
My ES chips run without any faults. The only problem is the higher thermal rating of the CPUs compared to the standard. It makes the booster fans run above 1,900 rpm all the time. I can run the CPUs idle with less than 1% load and I can never get the fans under 1900. Tutor used water cooling but I'm a bit of a chicken when it comes to water cooling because it is bloody risky to get it wrong. I would only use a certified system that is fool proven.
ATM I cannot stop the machine but I will see if I can do some checking later for you.
Would be nice if someone wrote a guide. Since there is so much information spread around. I like the above idea of using washers as to no over tight the CPUs. But Im not to clear on it. Also what type of thermal paste is the best, etc.
What might be wrong with the CPUs which would stop them working together, but work perfectly fine individually? The QPI interface?
