E4400 causing bottleneck?

Hi guys

I am new here and would appreciate some help with my new build.
I recently upgraded my rig (replaced the mobo and GPU)
I currently have:

CPU: Intel E4400 Core2Duo @2.2Ghz
MOBO: Asus P5Q SE
RAM: 3gigs total (a 2gig stick of Trancend jetram 800mhz and another 1 gig stick also 800mhz
GPU: Palit Nvidia GTX275
HDD's: 3 x 500gig Seagate 7200.12 and 1 old 200gig Seagate (all SATA)
PSU: 550W Coolermaster ExtremePower
Case: Antec 900
Screen: Samsung 2333SW 23" 5ms response

I had a entry level biostar mobo and an ASUS 9800GT 512mb before and scored +-8500 on 3DMark06 default settings. Now I'm getting only 10400 on my new build.
I am suspecting my CPU of causing a bottleneck.
Most games run fine though at max setting on 1920x1080 but sometimes I experience a bit of lag.

Any input would be appreciated
Thanks

Yes, it's getting bottlenecked.

It helps if you OC the chip. I got 3.0ghz from my e4400 2.0ghz.

E4400 is 200x10 and your board will do FSB1600 (clock400), so if you could head towards between 266x10 to 300x10, that will improve things.

For a stock E4400 I would expect your CPU score component from 3DMark06 to be between 1,800 and 2,000. Is this right?

E4600 is 2,100+ @ 2.4GHz
E5200 is 2,200+ @ 2.5GHz and 3,000+ @ 3.3GHz
E7200 is 2,300+ @ 2.56Ghz and 2,900+ @ 3.1GHz

You get the idea.

See if you can get that cpu score somewhere between 2,500 and 2,900 with your overclock. The rest of the 3DMark06 components will then fall in line.

For you GTX275 you'd be looking for these results:

SM2.0 8,000+
SM3.0 8,300+

Then CPU 2,500+

The final 3DMark06 score will depend on what overclock you go with, but considering your score can be obtained with a better clocked dual core and a 9600GT, I'd say somewhere in the 13,000 to 14,000 range is where you'll end up.

I'm estimating that. I don't have a GTX275 or E4400 on hand. I only have 9600GT, 8800GTS, GTS250, GTX285, HD4850 and HD4890 video cards to benchmark with, plus those processors listed above.

Hey man
Thanks for the reply and all the info.
I dont have my benchmark figures at hand because I'm at work at the moment but those sound about right.

I tried overclocking earlier and did 280X10 but it failed to boot so I set it back to 260X10 and still no luck. So i just went back to stock but the temps are now around 52 degrees Celsius where it used to be 40 at most.
I'm using the stock cooler by the way as I'm a bit short on cash after the upgrade.

Thanks I heard it overclocks quite well.
Can I overclock it with my stock cooler?
I've tried 280X10 and 260X10 but both failed.
Also note that this was my first ever overclock so I might have made an error.
Any help?

Apart from increasing the clock, what other settings are you changing?

If nothing, then best look at the following in BIOS:

Change FSB:MEM to 1:1 or the lowest MHz it will go.
Decrease your mulitplier (just for now), say to 8
Go to an easy overclock, such as 266 or even 250.
Up the volts to 1.375 for cpu and +0.05 for mem (again, just for now).

See what you get.

You might have to clear CMOS first, though.

Your stock cooler will work fine for what you're trying to achieve.
September 4, 2009 7:47:49 AM

I'm not changing any other settings.
I'll go try that tonight and let you know what happens.
Thanks for the help!

Oh by the way. What temps should I be seeing?
a b à CPUs
September 4, 2009 9:45:46 AM

Idle temps 35-38 degrees C.
Most load temps 38-52 degrees C.
Full load (Prime95) 52-58 degrees C.

Here's an E5200 333x10.5 @ 1.375V. Idle 37, load 50, but that was just for the shot. Loan under Prime95 is 56-57.



I know it's not the same processor as yours, but if you're not going beyond these types of temperatures, you should be fine.

If it's not idling under 40 degrees C at all then you'll need to back off a little, I think...

Hi again

This weekend I tried all of your suggestions but my PC wouldn't boot with any of the overclocks!
Even after clearing BIOS my startup temp is 70 degrees C +!!!
After idling in Windows it drops down to about 48-54 which is still very high for me.
Before, with my old MOBO, my temps never went over 35.
Is it possible I screwed something up when I put the CPU in the new MOBO?
I cleaned the chip's old thermal paste off and put new thermal paste on when I changed and the heatsink and fan are both firmly attached.

It seems best to cease any oc attempts at this point until that temperature is under control using stock (default) settings.

Can you tell us, when you boot and go straight into BIOS, what is the hardware monitor indicating the cpu and mb temps are?
Also, what is vcore at the same time?

That would be good to know, before doing anything else. Let this idle for five minutes and see what those three figures are at that point.

Then go to Windows and check the same three figures (if possible).

Now we have three sets of data for cpu temp, mb temp and vcore at start up (in BIOS), idle for 5 minutes (in BIOS) and then in Windows.

I'd really like to know if cpu temp you record for those three are similar before going further with this.

The seating of the cpu in the socket is straight forward. You've applied thermal paste and seated the heatsink correctly. Not much more you can do for the hardware.
September 7, 2009 10:06:35 AM

I will go check all of those tonight and let you know first thing tomorrow.
I know the hardware monitor is showing 72 in BIOS for the CPU and 22 degrees for the mb. I'll check the vcore again to be sure.
Oh and by the way I live in South-Africa so if my times are a bit strange, now you know why.

Yes, that's no good. There's someting wrong there for you to have 72C in BIOS.

I'm in Australia. Don't worry about the time zones. There are participants here from different parts of the globe. It makes it more of a 24 hour forum rather than just the revolving around the particular active hours on one continent.
September 8, 2009 6:13:27 AM

I'm back.
In BIOS at startup my CPU temp is 52 and mb is 15 degrees C with the CPU voltage at stock (1.088V)
After 5min in BIOS it's 64 for the CPU and 17 for the mb.
In windows after 5min it's 48 for the CPU and 19 for the mb.
Also note that last night was extremely cold weather so the temps were lower.
Also in Windows the AI suite that came with the mb showed that my CPU was being throttled to 1200mhz at times when idle.
Any ideas?
Could my temp sensor be faulty?

Did you put the heatsink on correctly? Try redoing the heatsink and reapply thermal paste. Maybe you are putting too much paste on. You can see how much to use by watching a youtube video
September 9, 2009 1:27:10 AM

It sounds like you may have a failing fan: check all the fans with the system on in Windows, especially the CPU fan. Also check all the power connections to the board.

I might have put too much on.
I didn't know how much to use so I put a thin layer on the whole cpu.
The fan seems to be working fine (running at 1966rpm).
I'll try redoing the heatsink and fan with new thermal paste.
How much should I use?
I have this: Zalman ZM-STG1 Super Thermal Grease
It comes with a little brush.

I went to check my benchmarks again and you were right about the CPU score: 1970
But my GPU scored really bad!
4000 for SM2.0 and 6000 for SM3.0
That doesn't look right.
I've read quite a few reviews about my specific GPU (palit GTX275) and every review were impressed with the card and it beat the 4890 in most if not all benchmarks
