E2200 @ 2.9GHz Temperatures

[manko]

I'm running my E2200 M0 with the 266/1066 BSEL mod and 1.45V mod. CPU-Z 1.45 shows 2926MHz and voltage around 1.376V. The motherboard is an ECS 945GCT-M/1333 (V3.0) and I'm using a Corsair HX520 PSU.

I'm now running Orthos Small FFTs (1 hour so far). CoreTemp 0.99, with a Tj. Max of 85C, shows my current load temps as 82-83C. Idle is around 40C. Is this way TOO HOT for Orthos? I'm using the stock fan with Artic Silver.

I've been searching around and it seems that CoreTemp may be mis-reporting or the Tj. Max may be wrong (off by as much as 15C). I heard CoreTemp 0.96 might be more accurate, but it wouldn't run for me in Vista 64.

Has anyone run CoreTemp 0.99 with a stress test on an overclocked E2XXX? What temps are you seeing? 83C seems high, but if it's 15C over-reporting, then it would be closer to 68C.

I'm going to leave it running for now.


One more thing, in CPU-Z I see the Core Speed bouncing up and down from 2926MHz / 11x multiplier to 1595MHz and a 6x multiplier. I'm sure that Speedstep is off in the BIOS and I have the Power setting on maximum performance. Why am I seeing this Core Speed/Multiplier bouncing up and down? Is it really changing or is CPU-Z just mis-reporting because of the BSEL mod?

Get an aftermarket cooler?

Definitely need a better cooler. My e2160 at 3ghz (1.4v) peaks around 57c in Orthos using a Scythe Mungen or what'ev it's called... Kinda like TRUE cooler. You really shouldn't spend any time higher than the 65c range with that CPU... At your current temps, it's not long for this world... Your voltage is fine, but you definitely need to cool that thing down. If you can shave 20c off, you'll be in good shape, and may even get more speed out of it.

I may do that, but I have heard of plenty of people running this chip at this speed with the stock HSF. I'm really wondering if it's actually running this hot or if this is a known bug with the E2200 and CoreTemp.

This is a budget build and I don't want to buy an expensive HSF only to find out that CoreTemp is still reporting the wrong high temperatures.

Right now, I'm just testing the system in an old case while I wait for the new one to arrive. Depending on the the temps in the new case, I may pick up one of the slim Zalmans, since I'll be running in a small SFF with low clearance.

Is that measured with CoreTemp 0.99 or what are you using to measure the temp?

 

[manko]

Well, I tried SpeedFan, RealTemp and HwMonitor and they are all reporting the same thing as CoreTemp. Orthos ran for 2 hours without a problem, but I just stopped it. I'll wait until I hear more feedback on the correct target temperatures with the E2200 and stock cooler at 2.9GHz.

After I stopped Orthos, it dropped back down to 40C.

I don't normally do anything that will stress the CPU this much. I'm not going to pick up a video card for gaming until the new ones are released next month, so I guess I'll see how my temps are under normal, everyday usage.

I just ran a quick test with 7zip. I was running in the low 90% of CPU and brought the temp up to 56C.

I think 40C is very high for idle. This should probably indicate that the thermal paste was not applied effectively, or that the HSF needs to be reseated and ensured it has proper contact with the CPU. As an idea, I'll tell you my current configuration:

E2160 (1.8GHz) @ 2.90GHz w/ stock HSF
9 x 322 with 1.4250V
Gigabyte P35-DS3L
Tested stable for 8 hours.

I use HwMonitor and Orthos. Idle is about 32C and max load is 69C. For 2.9GHz, I think stock cooling should be okay. I really recommend you re-seat the HSF as IMO you don't need an aftermarket one for a relatively "low" o/c (with respect to the E2xxx series). I'm also in the same boat as you, on a budget and don't really want to pay an extra $30-$50.

Thanks for your input. It sounds like my temps may be off by nearly 10C+ compared to what they should be with the stock cooler. I'm not sure, but I think the E2200 comes with a slightly smaller stock HSF than the other E21XX series chips.

I will see if I can do a better job seating the stock HSF.

I will be putting this system into a SFF case with a very limited space for an aftermarket cooler, so I only have a handful of choices which cost almost as much as the CPU itself. I'd like to try and get reasonable temps from the stock cooler if I can. I just want this system to hold me over until I can upgrade to a reasonably priced Nehalem system next year.

Yeah...I was going to suggest going with an arctic Freezer pro, but it is a very large HSF. Lowered my temps so much...My stock cooler gave me idles around 40 or so..now I idle at 30C which is pretty crazy. Make sure you have good air flow out of your case too

 

[nyker96]

I have a E2140 M0 at 3Ghz@1,345v BIOS setting in IP35-E board, runs about 22-24C idle, 46-48C loaded. using a AC freezer 7 pro cooler on this modest setup. I think your cooler is probably the problem. If your case can take it, get a Vendetta 2 cooler. one of the best right now, surely can keep it lower than my temperatures and will certainly be loads better than the stock Intel cooler. BTW temp is from speedfan 4.3x

Thanks for all the comments!

I tried different voltages and reseated the HSF each time and now I'm getting numbers more like jesterb84 posted. I think I originally had a bit too much Arctic Silver, but I'm not sure how much difference that made.

In my original post I had started out with the 1.45V mod, CPU-Z was reporting 1.376V.

I tried the BSEL with no volt mod, but Orthos crashed within a minute (at 57C). The interesting thing was, with no volt mod at supposedly stock volts, CPU-Z showed between 1.20V and 1.216V.

Those volts seem low, but the stranger thing was that when I ran Orthos before it crashed, CPU-Z show the volts dropped even lower, to 1.184V. Without Orthos running, it stayed above 1.20-1.21V, so it seems like this automatic undervolting might have caused Orthos to crash.

I had disabled Speedstep, C1E and Spread Spectrum in the BIOS, but the chip still seems to undervolt itself. Or maybe it's the motherboard.


Anyway, I had success with the 1.4V mod, CPU-Z reported 1.248V - 1.264V. This is weird, because this seems to be lower than the stock voltage should be, even though I had the 1.4V mod on.

My temps with the BSEL and 1.4V mod (1.248-1.264V actual), were 30-32C idle and 42-43C at 90%+ CPU compressing some files with 7zip.

I ran Orthos stable for 8 hours at 65-68C. Again, the chip seemed to undervolt itself down to 1.232V (from 1.248-1.264V) under load. The 68C temperature showed when the screen was on, but if the screen was off I think it dropped down to 65C, because that's what it showed for a few seconds when I moved the mouse to unblank the screen.

I think some of the extra temp, the few degrees between 65 and 68, might be due to the overhead of the integrated graphics. I don't have a video card yet, but it will be interesting to see if the load temps go lower because the CPU doesn't have to manage the integrated graphics or if a dedicated video card just heats up the case a lot more from its own GPU core and memory.


I'm going to hold off on buying a new HSF until I get my new case and a video card. I'm testing now in an old case, so the airflow may be better in the new one, but the video card may create more heat. Then I'll see what the temps are under normal usage, during HD video playback, encoding and gaming. My temps now seem borderline okay, but if they are a few degrees hotter in my final setup, then I'll have to pick up a new HSF.


My fan clearance is only 78mm and 110mm wide, so I can't use any of the popular, standard coolers. I'm looking at the following coolers, but I will probably go with the Enzotech even though it costs about as much as my CPU.

1. Enzotech Extreme-X (Enzotech Ultra-X) - needs slight modding and mount fan underneath

2. Zalman CNPS7000 - older, but the new ones are too big for my case

3. Scythe Shuriken SCSK-1000 - reviews are not so great

Get a better cooler.

I run my Celery E1200 w/ an Ultima 90, & it gets pretty cozy once you start upping vcore. I don't want to imagine temps with the stock cooler.

I have no doubt your temps were accurate with the garbage stock cooler.

I'm gathering you say you can't use tower coolers?

How 'bout the new Noctua: http://www.frostytech.com/arti...iew.cfm?articleID=2280

Actually it's very good for a down facing one IMO.

Also will be WAY quieter than the Enzotech.

My temps are now down to 30-32 idle and 68 under Orthos. Not great, but a bit better now with lower voltage and a re-seated stock HSF. They will probably stay in the 30s and 40s under moderate use.

Thanks, but I think that Noctua is too tall even without the fan and it looks like I wouldn't be able to hang the fan underneath.

The Enzotech has a low speed setting, but if it's too loud, I might keep the Enzotech heatsink and mount one of those slim Noctua fans underneath.

Hey, after the HSF reseat seems you got it right on. Those 30-32 idle and 68 load temps are just like mine. You mentioned a small form factor case, seems space is also a budget for you.

I don't know about the other fans but maybe you should consider the Arctic Cooling Alpine 7 (Newegg - $14). It's no larger than the stock HSF and Anandtech reviewed it along with the Freezer Pro and the results were positive (just google the Anandtech review). I've never used the Alpine 7 and I don't know what your target temps are but it seems that it reduced the X6800 by 9C on load (don't know if that is enough for your needs). I heard the downside is you must remove the motherboard to install something underneath the CPU tray but as you said you were switching cases anyways... Maybe someone else can comment on the Alpine 7.

Thanks for the suggestion. I had a look at a few of the reviews. I think it's just a bit too tall with the fan on top. However, it might work with a different 20-25mm thick fan instead. One of the reviews said it wasn't recommended for overclocking and that it only gives a slight improvement over a stock cooler with the fan on high.

It does show me there are more options out there though. I'll do some more looking outside of the usual suspects to see if I can find a few more moderately priced low-profile HSF options.


Akasa AK-961 - This one looks promising, but it doesn't seem to be available in the US.
