Core 2 Duo T9300/T9500 processor compatibility

webadmin@intel.com — Wed, 22 May 2013 17:21:10 GMT

I'm new here in the community, so I ask for your understanding and help, if I'm not asking correctly, ok ?

Well, I would like to know, if Core 2 Duo T9300 or T9500 processors, are compatible with an Asus K50IJ laptop. I intended to replace your current Pentium Dual Core T4300, by one T9300 or T9500 ( that I have mentioned above ), to make it faster. I believe that they are compatible, because they have the same socket and FSB, but I do not know if BIOS is compatible. Can you give me your opinion ? My operating system : Windows 7 64 bit, 4 GB DDR2/800.
Thank you, and sorry for my bad english

Why is there 1.65v RAM on Intel's own Memory compatibility spreadsheet.

webadmin@intel.com — Wed, 22 May 2013 17:04:01 GMT

If Intel processors don't support more than 1.5V memory for SB and IB why are there 1.6V and 1.65V RAM kits listed in the Compatible Memory for 1st, 2nd and 3rd Gen Intel Core i5 and i7 processor spreadsheets?

Please help

Hi Intel

I have bought Intel Xeon E3-1220 v2 processor.

I am testing Linux PREEMPT-RT on this processor. I created a test to see the time it takes for the OS to handle the clock tick.

My test is as following: I create a thread with highest priority ( can be preempted only by interrupts), whose task is just to do a small calculation in a loop of 45000 times. This task takes 102 µs to be finished.

If a clock tick happens while the task is executing, then this task is interrupted for some time until the interrupt is handled. ( aka: in normal case, the task takes 112 µs and if a tick happens, then the task takes 120 µs, which means that 8 µs are spent by the OS to handle the clock tick interrupt). I did this procedure around 100 times and I saw that each 1 ms I got a clock interrupt as the OS clock tick is running at 1000 Hz. so the normal values should be 102 µs if no tick happens, and 110µs if a clock tick happens.

This was perfect test on Intel core i7-930 @2.8GHz.

If I do the test on processor Xeon E3-1220 v2 @ 3.1 GHz, the task takes shorter time ( 102 µs) as it is faster processor 110 µs if a tick happens.

The strange thing I see on this processor that sometimes I get values around 120 µs, which means that some kind of interrupt happened and preempted the task for 18 µs. If it was clock tick, then it should take 110 µs.

so the processor is generating some kind of interrupts.

If I do the test with loop of 5000 instead of 45000, I do not see anymore such strange values.

Synthesis: if I do a task which is looping 45000 times on intel xeon, I start to get strange interrupts, which is not the case on i7-930.

If I do the test with loop of 5000, the interrupts disappear.

what could be the issue?

Rendering Workstation

webadmin@intel.com — Tue, 21 May 2013 17:43:33 GMT

Hi all

This is my first post so hope it will be answered, i'll try to make a simple one. Basicly I do renderings of an interior/exterior scene using Win7 64 bit and hp z800 with 2x Xeon E5530 @ 2.40 GHz cpu with NVidia Quadro 3800FX graphics card, and 16gb ram. With 3DS Max Design 2014, Vray2.4 addin it takes up to 10hours of calculation for a complex scene in HQ at 3000x3000 pixels. What I want is to use Dual Xeon E5 cpu with 32 or more ram with a gtx titan or Quadro 4000k graphic card and fasten this process. Has any one got any idea or better suggestions for this issue, or anyone uses a computer like this or better one? Any idea about Xeon phi coprocessor can be a better solution?!? It would be work in a workstation to improve speed in the rendering process?!?!?

Tnx.

Salve a tutti,

questo è il mio primo post e spero che qualcuno possa rispondermi, quindi cercherò di spiegarmi bene. Di media sviluppo renderings di interni ed esterni utilizzando una workstation HP Z800 con sistema operativo Win7 a 64 bit equipaggiato con: 2 processori Xeon E5530 @ 2.40 GHz, scheda video NVidia Quadro 3800FX, 16Gb di ram. Il software di sviluppo che utilizzo è 3DS Max Design 2014, Vray2.4 e per il calcolo di una scena complessa ad alta qualità e risoluzione a 3000x3000 pixels impega di media 10 ore di calcolo. Vorrei passare ad una nuova WS equipaggiata con doppi processore della serie Xeon E5, con 32 o più gb di ram, con scheda grafica GTX Titan o ancor meglio una Quadro 4000k per aumentare la velocità di sviluppo. Qualcuno ha una migliore soluzione o consiglio? Affiancare un coprocessore Xeon Phi potrebbe esser una migliore soluzione?!? Funzionerebbe installato su di una WS per diminuire i tempi di calcolo relativi al processo di render ( CPU based ) ?!?!?

Grazie.

processor E5-2620 supports RDRAND?

webadmin@intel.com — Mon, 20 May 2013 16:04:25 GMT

Hello

I have a server platform Intel R1208GZ4GC and E5-2620 processors. I'm trying to use RDRAND, to generate random numbers. To put this code:

int _rdrand16_step(unsigned short *therand) { 
 unsigned char err; 
 asm volatile("rdrand %0 ; setc %1" 
 : "=r" (*therand), "=qm" (err)); 
 return (int) err; 
  }

However, when compiling the error:

{standard input}: Assembler messages:
{standard input}:7191: Error: no such instruction: `rdrand %dx'
gmake: *** [../../main/main.o] Error 1

Operating system FreeBsd 8.3

Help me, please.

Xeon E5630 - Sees Only 16 "CPUs"

webadmin@intel.com — Fri, 17 May 2013 20:48:53 GMT

Gentlemen,

My client has three stations "PowerEdge T610" with 2 processors E5630 (in bios) (Windows E5649). My XenServer (Bare Metal Hypervisor) sees only 16 "CPUs". These 2 processors have 4 cores each and 8 threads for each core.

The problem is that XenServer sees only 16 "CPUs" when he should see 2x4x8 (CPUsxCoresxThreads) 64 "CPUs". Namely, 32 "CPUs" for each processor. Is that correct?

I've Recently upgraded this bios. What could be wrong? This is a limitation of Linux? What can I do for this my client?

Thanks!

Atom S1260 Server Processor

webadmin@intel.com — Thu, 16 May 2013 19:02:18 GMT

Hi Intel Community!

This is my first post in these forums. I hope you guys are able to help me.

I'm building a NAS and am aiming at using the Atom S1260 processor for it and I have got a relatively simple question that I haven't been able to find an answer for.

Can the Atom S1260 processor be used with Sata port multipliers?

For example:

http://www.addonics.com/products/ad5sapm.php

Note that both don't slot into PCI lanes.

Thanks,

Will there be a LGA2011 Haswell Xeon processor?

webadmin@intel.com — Tue, 14 May 2013 16:37:09 GMT

Hi, I'm would like to upgrade our compute nodes from Sandybridge Xeon E5 2658 to a Haswell processor and get the benefit of AVX 2.0. Does anyone know if there will be a Haswell processor that uses FCLGA2011?

Dual Xeon E5 or Singel Xeon E5 ?

webadmin@intel.com — Wed, 08 May 2013 18:31:32 GMT

Hi!

Planning of building a graphic workstation. The WS-system will use the whole suite of CS6 Master Collection.

It is really hard for me to choose which way to build the system, i don´t get the help i need from Intel, Asus and other internet resources. Maybe, and hopefully you can help.

Questions:

- Is dual Xeon E5 2630 better than a single Xeon E5 2660?

- Motherboards, what to choose, Intels W2600CR2 or Asus Z9PE-D8WS, or other?

- I will use at least 32GB RAM, i don´t find compatible (OVL) memorys list to Intels W2600CR2?

- If i crank up RAM to 64GB RAM, will it be a difference?

I intend to use a single Quadro K4000 graphic card. Velociraptor HD, Samsung PRO SSD, 1000W power.

I REALLY appreciate your answer.

Best regards: Erik

Intel T1300 Upgrade

webadmin@intel.com — Tue, 07 May 2013 20:51:26 GMT

Hello and a Happy Monday, to all

I have a Toshiba Satellite P105-S6004, that works very well and suits my needs, somewhat. I am a college student and unable to purchase a completely new laptop, at this point.

The Intel T1300 runs at 1.66 GHz. I looked at upgrading it, and according to websites such as these:

http://forum.notebookreview.com/hardware-components-aftermarket-upgrades/492751-help-me-please-can-i-upgrade-processor-toshiba-satellite-p105-s6147.html

I can only upgrade to an Intel T7600.

I'd like to go to as many GHz, as possible.

According to this list, the highest I can go, is a T7600, as well: http://www.cpu-upgrade.com/mb-Intel_%28chipsets%29/945GM_Express.html

My chipset is mobile intel 945 express chipset family.

How do I determine the maximum GHz, that my computer can handle?

Are there limitations? Is it a gamble and I hope my laptop doesn't explode? I'd appreciate help on figuring out the highest that my system can handle, as I want to increase processor speed.

Couldn't I just upgrade to the Intel T2700? Won't any Intel processor work?

Thank you in advance, for any assistance, and have the best possible week.
