Hybrid Studio upgrade CPU

Hi,

Please find below the list of processors that have been tested by Dell on Studio Hybrid 140G:

 

Dell does not offer processor or motherboard upgrades for purchase as discrete items, nor does Dell recommend upgrading the processor or motherboard in any given system. Therefore, Dell cannot support systems in which the motherboard or processor has been upgraded through third-party services or products. For more information, you can refer to the article ID: 52114 on: support.dell.com .

Please reply for further clarifications.

First of all thanks for your reply. I assume Dell won't support the upgrade of their pc, but this config is now 5 years old, so not having any warranty on it..... I just want to use this low energie hybrid again for his design and his quality, but i Just wonder more od this one. But please could you repost this list of processor, not really readable for me on my phone at this time :( But if i saw well there is no core2quad in this list of cpu!? I am right!?! If yes could you tell me what is the technical incompatibility with core2quad!? Thank for helping me.

Hi,

Thank you for your quick response. All the processors listed in image are Core 2 Duo, Dual core or Celeron processors.

Most of the Quad core processors have Lithography in between 45- 65 nm and have more power consumption than the Core 2 duo or Dual core processors. So it generates more heat when it is used. Studio hybrid has form factor limitations and if a quad core processor is used, it may cause system instability and overheating issues. Moreover quad core processors have not been tested by Dell product group team for these systems.

Please reply for further clarifications.

Thanks for the explication, as you can see, I not a noob, but there are some tech specification I don't really know :(

In this case, the core2Quad Q9100 I hope to install in the Dell Studio Hybrid have a 45nm lithography and is voltage range is exactly the same as the T5750 id est the CPU in the motherboard of the Hybrid.

Moreover, if I check the T° Junction of the listed CPU you give to me, the more powerful one (T9500) have a 105°C T° Junction and the Core2Quad Q9100 have a 100°C T° Junction (yes the actual CPU have only 85° T° Junction, but the listed CPU can have max T° overheat of the one I hope to use)

So the only think really that can change betwin T5750, T9500 and Q9100 is the maxTDP (35W for the first two and 45W for the quad but I don't know really what to understand by MaxTDP :()

So if I understand your last post, the problem of the quad is "only" a T° problem, and the motherboard itself van see and use quad core ???

Thanks fot lighen my !

Hi,

Thank you for your quick response.

I would recommend you to check the following:

Need to check	Processor Q9100	Processor T9500	Processor T5750 (Studio Hybrid 140G)
VID Voltage Range	1.050V-1.175V	1.000V-1.250V	1.075V-1.175V
Max TDP	45 W	35 W	35 W
Lithography	45 nm	45 nm	65 nm

 TDP refers to ‘thermal design power' which means the maximum amount of power the cooling system needs to dissipate in order to keep the chip at or below its maximum temperature. For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat without exceeding the maximum junction temperature for the computer chip. It is possible for the processor to consume more than the TDP power for a short period of time that isn’t “thermally significant”.  For example, a processor might consume slightly more power than the rated TDP value for say one microsecond but then consume less power than the rated TDP value for a long period of time.  Over a long period of time it might affect the hardware components of the computer.

Since Quad core processors have not been tested by Dell product group team by this particular system, I would recommend you to consider all the physical and variable factors that might hamper computer functionality over long period of time.

Please reply for further clarifications.

Thanks for all your help, but i don't understand this spec.

I saw the max TDP of the core2quad, and know this one is more demanding power from the power suply, but I think it's an half problem cause I actually use an SSD drive and not an HDD one.

Did you point a thermic problem of the configuration with this CPU??

Actually this is my sensors capture :

Do you really think the 15° of T° Junction in more for this processor can affect the all system and the motherboard itself or all other hardware component ???

Hi,

SSD consumes lesser power than a normal HDD and that’s not the major issue. When comparing processor power specifications, we believe comparing TDP to TDP is the most “apples-to-apples’ comparison that can be made. If you are comparing the core temperature of the junction, it is very important to know that there are very small resistors, capacitors on the motherboard. Even a watt above the max TDP (even for few microseconds) can cause issues on system motherboard or damage those small capacitors, resistors (Similar in case of temperature of junction). This may lead to ‘no post’ issue. Comparing Q9100 to T5750, there is a difference of 10W power. Dell product group team has not tested the quad core processors on this computer. So, I would recommend you to consider all the physical and variable factors before going for an upgrade.

Please reply for further clarifications.

If I understand you, the real deal with the core2quad is the TDP (if I understand this value, it's the power of temperature dissipation of the power cooling)

So I must renounce to the core2quad processor!?

But if I check the processor catalog, I see also the core2duo T9900 who is the most powerfull core2duo in the socket P

If I'm right this one also have the same socket, and the same Max TDP.

I i'm right ? Can I use this CPU on the Dell Studio Hybrid?

The goal of this is to upgrade the Dell Hybrid to the most of this physical capacity (and without issue ;) )

Below is the brief comparison of the specs for T9500, T9900 and T5750 (which was shipped with your computer) :

Need to check	Intel Core 2 Duo T9500	Intel Core 2 Duo T9900	Intel Core 2 Duo T5750
FSB Speed	800 MHz	1066 MHz	667 MHz
Instruction Set	64-bit	64-bit	64-bit
Lithography	45 nm	45 nm	65 nm
Max TDP	35 W	35 W	35 W

T JUNCTION	105°C	105°C	85°C
Clock Speed	2.6 GHz	2 GHz	3.06 GHz

Earlier, we were only comparing the Q9100 and T5750 on basis of TDP. There are some other things that needs to be checked before upgrading the processor like the FSB, Clock speed of processor, Dimensions, # Cores etc. There may be a small concern related to the FSB and clock speed supported by motherboard for T9900. T9500 has the FSB of 800 MHz and T9900 has FSB of 1066 Mhz. FSB connects the computer's processor to the system memory (RAM) and other components on the motherboard. These components include the system chipset, AGP card, PCI devices, and other peripherals. Most computer processors run faster than their system buses, so the FSB speed is typically a ratio of the processor speed. The other factor that may affect is the clock speed of processor T9900. The clock speed of a CPU is the frequency that a processor executes instructions or that data is processed. There may be an issue that FSB and clock speed of this processor may not be supported by motherboard and may cause issues with other components of your computer; however T9500 is tested by Dell product team on Studio hybrid without any issues. For further comparison, you can refer to the link: http://intel.ly/ONsHYJ

Please reply in case you have further questions.

So if I really understand the onlly chose I can have to upgrade the CPU is a core2duo and the max frequency of this one I can mount is a 2,6Ghtz with the T9500, all other one (Core2Quad or more efficient can have issues with other hardware part or can just be not recognised by the motherboard itself....)

I must tell I'm a little disappointed cause I really hope to upgrade this computer for more powerfull perf, and I not really sure the gain of 600Mhtz was so pretty than I hope.....

But if I read and understand all you explain, it's my only alternative !?!

Hi,

I understand your concern. T9500 is the processor (bearing the maximum capacity) tested on your computer by Dell product group team. We have not tested T9900 with your computer. You can upgrade to T9900 but it may work or may cause system instability issues.

Please reply in case you have further questions.

Hi, I hope you dont mind me chirping in on this conversation....?

I also have a studio hybrid 140G that I use daily and had for about 4 years or so. I'm also thinking about upgrading the components as I cant find anything small in size and versatile enough to replace it. SO, I was wondering if I could replace some of the parts inside the casing...?

Its currently running a T3200- 2Ghz Processor and 2Gb of Ram. I've checked on the dell website about the RAM and thats easily sorted to max it out to 4Gb.

However, the processor upgrade I'm a bit unsure about because i obviously dont want to fry anything inside the case by changing to a better/faster upgrade.

Could you please suggest what compatible processor I could use to speed up the unit without causing damage to the machine and its components..

I notice in earlier posts you talk about a T9500... Would this be fully compatible and suitable to power the equipment without causing damage ??

 

Many Thanks

 

Mark

Hi Mark,

Dell has tested T9500 processor with Studio 140G without any issues. You may take a look on the previous post for list of all the processors tested by Dell on your computer [compatible with Intel’s 775-pin (LGA775) socket]. You may also check a comparison of T3200 and T9500 from the link: http://intel.ly/XkNSXB

Hi Bud, I have recently replaced a p8600 with a t9500, graphics having trouble keeping up.

Its been over a month with no problems, in fact I have no need to consider a newer pc at

this point.
