Overclocking

[saXoni]

Hey guys.

I just overclocked my Intel Core 2 Duo E7400 from 2.80GHz to 2.96GHz. While just surfing on the internet etc. the temperature is going up and down between 33 degrees Celsius and 34 degrees Celsius. Does this sound normal? I'll post back when I've tried playing PR.

Also, in Catalyst Control Center, there's an ATI Overdrive. There are two bars here.

One of them says "High Performance GPU clock settings", where the line is set in the middle of the bar at 700MHz. The minimum is 500MHz, and the maximum is 870MHz.
What does this mean?

The second bar says "High Performance Memory clock settings", where the line is set about at about 1/3, on 1150MHz. The minimum is 1000MHz, and the maximum is 1430MHz.
What does this mean?

My specs:

Operating System
MS Windows 7 Home Premium 64-bit SP1

CPU
Intel Core 2 Duo E7400 @ 2.80GHz 33 ?C
Wolfdale 45nm Technology

RAM
4.0GB Dual-Channel DDR2 @ 420MHz ( 5-5-5-18 )

Motherboard
ASUSTeK Computer INC. P5QPL-AM (LGA775) 27 ?C

Graphics
BenQ G2420HDB (1920x1080@60Hz)
LEN L193pC (1280x1024@60Hz)
ATI Radeon HD 5700 Series

Hard Drives
488GB Seagate ST3500418AS ATA Device (SATA) 26 ?C

Optical Drives
ATAPI iHAS124 Y ATA Device
DTSoftBusCd00



Thanks,

Load temperatures are all that matter.

- Prime95 64bit, Intel Burn Test to torture test it
- Realtemp & coretemp to monitor cpu while torture testing
- Wouldn't recommend GPU overclocks, performance gain to risk ratio is generally lower*.

* Overall system benchmarking I mean - in most gaming applications the effect is negligible except on really decent overclocks [much > 5%].

Well, I'm not the real overclocker guy but sound to me to me like you OC'ed your CPU just by adding voltage which would explain the high temperature dropups.Afaik CPU's underclock when not ''fully'' used (as reading on internet ) and than again as soon you start your activity again, the CPU gets voltage ''shockwave'' as soon you start on working on something again.

If thats NOT the case, I guess i have no idea...
(well perhaps except - make sure PC is clean and dust free and check if your cooler isnt loose as well the thermal paste is even there AND applied properly..)


Oh, and as of 5770, I dont have that card so I cant really tell how far u can push that card but usually the cores can take some more than memory.
Afaik though CCC has the utility in performance tab named Autotune...you might wanna try that

Omg i guess i really cant read anymore, I've read those temps as 33 and up to 43 ...

In this case, feel free to scratch what i wrote before as temps btw 33 with +- ~3 degrees is totally normal.Furthemore not every core has the same temperature.

My apologies for misleading post Saxoni ops:

That CPU overclock that you did wont effect performance much, something like 0,5GHz overclock becomes notable. Modern day CPUs are very hard to kill with OC if you don't switch the safety things off. You can also safely OC the gpu from overdrive, if you notice graphics glitches or it crashes the system, lower them.
Also Intels default coolers are not meant to do overclocking.

The temps are fine, limit for that chip is 74.1c per Intel. You should be able to hit 3.6ghz @ 1.31vcore stable with that chip although I would take it to 3.4ghz and leave it there if it were me because that should put you at 31-32c idle and 50-55c load. Bump the vcore to 1.31 and clock it to 3.4ghz. Reduce the vcore by .1 and reboot until unstable at reboot then increase by .05. Run Prime95 to test, if it fails, bump by .05 until it passes. Once you pass, run at least a 1 hr Prime95 (I run 12 hr) to burn in.

Also think about a 3rd party CPU cooler, not the stock fans.

*WARNING 1* Use small increase increments of voltage (usually .05) at a time, don't do large increases.

*WARNING 2* Always watch temps while running Prime95. On that CPU, 55c would be my limit at stressed levels. It can handle more but I wouldn't push it personally.
