A question about X9000 ES cpu (xps m1730)

Hi guys,
finally i got my x9000 from shirleycpu over ebay for 250 euros, shipped with ups in 4 days, no customs, all good.

I was pondering about the strange behavior this cpu have regarding temps.

First of all, a CPU-Z screenshot:



As you can see this is a genuine ES sample, pretty rare as much as i read around.

Anyway what im questioning here is: its normal that on boot the second core temperature reading is not so "real"? I meanm sometimes it says 149c, sometimes doesnt.

But when in game, or stress testing the cpu, temperature reading goes normal without crazy jumps. I know the cpu is working because both cores are seen in Peripheral Management, under "Set Affinity" option in Task Manager and in "performance" tab under Task Manager, where it shows both cores with two graphs.

Im just trying to understand what does ES stands against OEM cpus. So far i understood by speaking with Magnus72 (ill never cease to thank him enough, he helped me alot!) that OEM cpus can run with a more lower voltage.

As an example to use the cpu at 3,8ghz i need to use 1,437v, while on 3,6v i just need 1,350 (like x9100 in my eurocom).

Also my cpu is labelled as "X9000 q174 is ES(E0/C0) Final version".
What does q174 means?

Thank you all!

 

I believe that is the SPEC Code, q147:
Q174 (Intel Core 2 Duo Mobile X9000)

You probably should have gone with an E0 stepping rather than a C0.

The E0 stepping needs less voltage to be stable from what I have read.

 

The X9000 CPU does not have an E0 stepping unfortunately. X9000 only has an E0 stepping. It's only for the X9100 which has two kinds of steppings.

I believe it's one of those spike temps that you see in HWMonitor. Try using the updated version of it.

PS, I am also using Q174 X9000 as well, and temps are well read. Q174 is essentially the final Quality Sample CPU for the X9000.

Hope this helps.

 

Thanks MH and Som..but Som im confused,what you mean by spikes and updated version?
As i said with c-states i see those spikes..however evrything is working perfectly!

 

So your X9000 overclocks better than your X9100?

 

Yep , at least is more efficent and cooler. I can top 4ghz but it requires much voltage. 3,8 is fine thought.

Btw i think the problem is the second core sensor..but only in c-states. As long as the cpu is in normal eist mode temps are reported correctly even under load with core temp.

 

Okay ive ran a 3dmark06 benchmark, thing that i didnt before.



This should be a good score, im taking SomeFormOfHuman score as a reference althought the gpus are more powerful (9800 GTX sli vs 8800m GT).
That should explain a rough 2000pts difference vs a 4ghz clocked gpu.

Anyway something is definitely different with my cpu. SFOH can run his at 1,5v clocking 4ghz while i cant....also the wrong temp reading is mainly when c-states kicks in, specifically around 2% of cpu usage.
During gaming or other cpu tasks, when the load rasies above 10%...BAM! magically the reading works perfectly and second core is shown healty and working even in HWMonitor.

I guess that ES cpus arent all the same...
