My first overclock.....

[gdextreme]

I have recentlu upgraded my Computer and have the following configuration:

Intel Pentium Dual Core E5200
Gigabyte GA G31-S2L mobo
2x1GB Kingston value RAM 667mhz

I have set my FSB to 230mhz and multiplier to 12.5 and CPU voltage was not changed.
RAM is at 587mhz (I downclocked it as otherwise it would have gone worked at 700mhz)

My CPU temperatures when running Orthos for 20min as reported by coretemp are:

Core0: 56-57degree celsius
Core1: 50-51degree celsius

At no load both cores show 37-41degree Celsius

Is this okay? My room temperature is around 22 degree celsius.
Should I try for 3.2ghz by upping the CPU voltage? If yes by how much?

 

[Kraeoss]

no volt increase yet just see how far you can get on stock volts. and those temps look normal are you using a aftermarket cooler or the stock ?

 

[gdextreme]

The heatsink I am using was meant for a Pentium D 820. I dont know if it is meant for overclocking but it has a lot of copper and is big and heavy so I am assuming it is good enough.

 

[Philippart]

if it is "good enough" is determined by the temps you get

 

[Kraeoss]

Get This it's gonna keep you quite cool... and crank up that overclock

 

[gdextreme]

I have been running Orthos with CPU at 3ghz for about 30 minutes now and temperatures remain at maximum 58 on Core0 and 55 on core1. I can't buy anything from newegg cause I live in India. Are these temperatures normal or a little high? Should I reattach the CPU. I have put thermal paste but I don't know if it is properly put. Should the heatsink be a little warm? Mine is cool to touch. I am no hardcore overclocker. Just a newbie out to get as much mileage from my current hardware .

Which temperature should I trust? http://img75.imageshack.us/my.php?image=86666044cb5.jpg

 

[Kraeoss]

i heard real temp is the most accurate.

 

[gdextreme]

Please tell me should the heatsink be warm to touch?

 

[Concillian]

Real temp has the correct Tjmax for 45nm CPUs by default.

You can configure the other programs with the correct Tjmax and they'll read the same as realtemp.

my e5200 topped out somewhere around 3.1 on stock voltage, I didn't really spend the time to find the precise limit on stock volts. You shouldn't have to worry about temps much on stock voltage if the HSF is mounted properly. You'll definitely start failing IBT / Prime / Orthose before you run into a temperature limit. The temps don't really start climbing until you push higher voltage.

Frankly I think you have the right idea with the e5200. Just use a stock-ish cooler and get what you can out of it. This is a budget processor. Doesn't make much sense to spend half the cost of the CPU on a HSF.

Set a temperature limit you're comfortable with, say 65C under Intel Burn Test load in real temp. Take things slow and increase voltage and FSB a little bit at a time until you get to the point where you're at your temperature limit. With that HSF this won't put you at insane voltages. You'll be in the neghborhood of 1.3v ± 0.05 which is quite safe. You should be able to get into the 3.2-3.4 range, I think. But really don't go in with a "speed goal" go in with max temp and voltage limits you're comfortable with, then be happy with what you end up at in terms of speed.

I tend to be quite conservative on my temps compared to some around here. But I like to know my systems can handle the summer heat, or a little dust build up inside the case without having to worry about it.

Now I am running at 3.125Ghz and still on stock voltages. I ran BOINC (distributed computing) for 8 hours and temperatures never crossed 53degree celsius in Realtemp.
In CPUz the FSB to Dram ratio is greyed out. Is there a software to know at what frequency the RAM is running?

sounds like those Pentium D heatsinks are made to deal with an inferno. Good one.

They'd have to be like that to control 130W of dissipated power (I could use a Pentium D for a room heater )

Anyways I am running at 3.25Ghz now and at 1.175V CPU voltage (Is this stock voltage?)
The BOINC inbuilt CPU benchmark says it is 2.9 times as fast as a Pentium D running at 3.118 Ghz (Check it out here: http://szdg.lpds.sztaki.hu/szd...ow_all=1&sort=rpc_time

I just checked my Windows Experience Index and the CPU score has jumped to 5.7. But what caught me offguard was my RAM Score: 5.9
How can a 667mhz Kingston value RAM get 5.9? I think my RAM may be getting overclocked too, but I have set the RAM divider so that the RAM is at 690mhz (approx). Is there some Memory frequency test which I can run from Windows? CPUz 's DRAM frequency column is greyed out. Memset says it is running at 571 Mhz.

You'll probably get much further than 3.25Ghz.

I don't think so because my RAM is running at the lowest RAM divider and still running at 693mhz (It is 667Mhz Generic RAM). I am actually running at lower than stock volts 1.167V from the stock 1.225V. Maximum temperature for core0 is 45 degree Celsius and 44 degrees C for Core1. I have also checked many benchmarks and My CPU is a wee bit faster than a stock E8400! I could probably get to 3.4Ghz easily with 800Mhz RAM but I am satisfied with this performance. Later I may buy 800Mhz RAM.

 

[Tempered81]

333 x 12.5 = 4162mhz. Your cpu will have a hard time with > 4000mhz. 333mhz fsb is stock for your DDR2 667 ram - so no problem for the ram there.

 

[gdextreme]

The lowest RAM Divider makes the RAM run at 693MHZ with 260mhz FSB. Is there a way to unlock more RAM Dividers

 

[Tempered81]

Just take your System Memory Multiplier off AUTO, and set 1:1 Ratio

Cpu Clock Ratio: 9 X
Cpu Frequency: ( 9 x 333mhz = 3ghz)
Memory Frequency mhz : 333 (667)

 

[gdextreme]

It says in my BIOS

Sysytem Memory Multiplier (SPD)

Auto
2.66
3.33
4.0+


In this I have selected 2.66 so that my RAM runs at 693MHz

Is that Pic in ur Sig real :shocked: An E8600 at 6.7GHZ:shocked:

 

[Tempered81]

you may have to make your host clock 333 and your multi 8, 9 or 10.
Please check out graysky's overclocking guide

 

[gdextreme]

I've already read Graysky's guide. I have checked all multipliers in my BIOS. 33MHZ FSB also but the SPD options remain same.

 

[Tempered81]

ahh, so you did 333mhz fsb, and lowered the CPU clock multi, and it still only gave 2.60 as lowest memory divider. blah.

So in order to get your cpu to clock higher you need to get faster ram, or up the vdimm/loosen timings and try a mild overclock on your current ram.

Pardon my ignorance but what do you mean by this?

3. Memory
You will need memory that can keep up with your overclocked system. Again, I?m not going to keep a list. You?ll see RAM listed with timings and speeds that I?ll decode for you using the following examples:

DDR2-800 (PC2-6400) 4-4-4-12
DDR2-1066 (PC2-8500) 5-5-5-15


? The first part is self-explanatory (DDR2 memory).
? The number after it is the data transfer rate. Simply divide it by 2 to get the maximum FSB speed for which the module is rated. Example: 800/2 = 400 MHz. Therefore, DDR2-800 can work on systems with a FSB of up to 400 MHz (anything more and you?re lucky).
? The PC2-XXXX is designation denoting theoretical bandwidth in MB/s. Some memory manufactures use this instead of the DDR2-xxx designation. You can calculate it for any FSB you want by simply taking the FSB and multiplying by 16 (rounded in some cases). Example using a 400 MHz FSB: 400x16=6400. So you?d need at least PC2-6400 to run on a FSB of 400 MHz.

The numbers after that are the main timings (clock cycles). In general, the lower these numbers are, the faster the memory. For more on memory timings, see this page.

DDR3-1333 (PC3-10666) 9-9-9-24
DDR3-1600 (PC3-12800) 7-7-7-20


? The first part is self-explanatory (DDR3 memory).
? The number after it is the data transfer rate. Simply divide it by 4 to get the maximum FSB speed for which the module is rated. Example: 1600/4 = 400 MHz. Therefore, DDR3-1600 can work on systems with a FSB of up to 400 MHz (anything more and you?re lucky).
? The PC3-XXXXX is designation denoting theoretical bandwidth in MB/s. Some memory manufactures use this instead of the DDR3-xxxx designation. You can calculate it for any FSB you want by simply taking the FSB and multiplying by 32 (rounded in some cases). Example using a 400 MHz FSB: 400x32=12800. So you?d need at least PC3-12800 to run on FSB of 400 MHz.

Basically, your 1.8v 667mhz 5 5 5 15 DDR2-PC25300 can run at ~ 2.1-2.2v 800mhz 5 6 6 18 DDR2-PC26400 if you wish to overclock by "increasing vdimm (1.8v to 2.1v) and loosening timings (5 5 5 15 to 5 6 6 18)"

Just an example.

I do not want to thread crap, but I am thinking of getting a E5200 to beat the current heat problem of my current pentium D 915 pressler that often soar to over 70C under any kind of load, and has gone as high as 80C. It idles at 54C.

So I wished to point out that the intel stock cooler that came with the pentium 915 D is not all that bad. It has a copper core and aluminum fins. The intel HSF that comes with a boxed intel e5200 combination processor w/heat sink and fan is seeming decidedly inferior from what I can read. All aluminum and much lighter in weight. Something like an arctic cooler 7 might knock 7 C off the top readings of the pentium D HSF, not enough to do me any good, but hold much promise out to the OP if he overclocks more.
