Intel Core 2 Duo E7200 Overclocking...

[TridenT]

I have not tried anything between 1.35 and 1.4v but at 1.35v the CPU does not go stable on Orthos. At 1.4V it is stable so far. (Like 7 minutes) I am running it at 400 x 9.5

I don't exactly like how high the temps are with this new cooler I got. (Big Typhoon by Thermaltake.. Should only be about 5$ AR) I get almost 70C under load.

What are your experiences with the E7200 and OCing?

So far mine are pretty crummy. I was hoping to hit 4.0Ghz, but I would have to crank the voltage even higher for that. (The 20mhz difference on the FSB drives this thing up a wall)

I was able to get 3.6GHz on mine with the stock HSF. around 70C using Prime95

 

[E4300]

Most E7xxx should max out around 3.7GHz with 1.36 in BIOS. I'm running 4.03GHz with Big Typhoon/E5300 @ 1.37 BIOS. Peak Coretemp is 49C under Orthos with 78F ambient. My E8400 runs a little hotter (53C) at the same speed and core voltage due to the additional cache.

If there is insufficient air flow in the case or if the cooler is improperly mounted, then you will see high load temp. Suspect you may have a bum chip.

I am not sure why everyone thinks they should be able to hit outstanding speeds,.. 3.8 is nearing the average maximum of these chips,... so saying it is a crummy overclock is just having too high of expectations first of all. Not every chip will hit 4.0 - 4.2 on air and that is not to say there is a single thing wrong with your chip,... it is a variety of factors. Getting to 3.6 is realistic for basically these chips to hit,... 3.8 is a very nice overclock with the chip,... any higher is just luck.

Also do you realize there is no perceptable difference between the chip running at 3.8 and running at 4.0????

I am aware. I just want to say, "My CPU runs at 4.0GHZ"

That's because they read some random report of someone on some forum somewhere say that such and such overclocks are "guaranteed," and thus feel entitled to it.

And because there are so many that oc their cpus and don't know how to really test for stability, or they just run a quick CPU-Z screenshot, with the chip at 4 ghz, where it's probably not even stable at 3.6 ghz. I see the web "screaming" with this kind of people and this is not applicable only for cpus, they're also doing it on videocards.

my e7200 is running at 3,5@1.35v bios. I can go higher but this one needs a lot more voltage. using Vendetta 2 cooler on it. i think the temp is 60-65C/full OCCT linpack load.

it looks like your cpu is slightly better quality than mine, I think you can do close to 4, just might not be worth the extra heat and voltages.

I could do 4.0Ghz if I upped the voltage to like 1.45v, I am pretty sure. I just don't want that much extra heat. It already loads around 70C and it's starting to get into the 80s and 90s (Fahrenheit) for ambient!

 

[big4x4]

I have my e7200 @ 4.0 ghz @ 1.184v under load. Forgot what it is in the bios since it has been so long! It has not crashed a single time!

Hell, that is one fantastic chip. :Q

 

[Cheex]

That's unbelievable!!!
Post a pic PLEASE!!!

Mine basically tops out at 3.8GHz but I run it at 3.6GHz for 24/7.

What's your VID?

@OP. Try raising the NB and FSB voltage by a notch. I heard they could have an effect on OCing, but I myself didn't change anything but the Vcore.

4Ghz is possible, but it depends on your VID. What's your VID?

Mine is the same clock (4ghz) 1.3V core, havent tried up or down......new oc......new sli rig...enjoying it. It booted in at 4.21......bsod.....was gonna read up on this chip see if I could raise the voltages some. The cool thing to me was my 3d 06 started at 11k.....ended at 18k and change after tweaking. These chips are fun. BTW..anyone out there know the 780i and can offer an opinion on these voltages:

cpu core: 1.32
fsb: 1.29
spp/nb: 1.4
mcp/sb: 1.525

any help or opinions appreciated.

 

[brblx]

mine will take 320 x 9.5 rock stable at stock voltage with the stock cooler. i'll pick up a new cooler eventually, and i'd be willing to bet it's going to go quite a bit further with a little voltage increase. it may even go further right now, i just havn't pushed it.

 

[TridenT]

I am skeptical of any claims of 4.0Ghz @ low voltages...

Show me at least an hour of Orthos stable with cpuz, etc etc.

 

[SantaAna12]

1.3 considered low? Thats my question. Ive run prime on this and game on it for hours. works for me.

 

[TridenT]

1.184V is considered extremely low.. That's below the stock voltage I believe.

1.3 is low for 4.0GHz.

 

[gwai lo]

Some E7x00's were fantastic chips and oc'ed well, there was a large db from XS for Wolfdales and some of them were good. However, it seems that the large majority of them were not so good. Mine requires 1.38 @ 405×9.5 under water.

Also I will have to agree with TridenTBoy3555 and say that I wanted 4 GHz just to hit 4 GHz. Overclocking is hardly for real world benefits anymore anyway.

 

[MagickMan]

4GHz @ 1.39v, and it's 24hr Orthos and IBT stable. I dug through 4 of them until I found this one, sold the others to friends and family. The others would do 3.5GHz with about 1.35v, and maybe a little more at 1.4v, but I didn't take the time to find out. I think mine could do 4.2+ with more juice, but I'd need to go to water.

 

[SantaAna12]

thanks for the replies on the voltages guys. I see 1.3265 on Intels site as the max for this chip. Is it considered normal to exceed this? Not trying to be a stickler.......just dont know.

 

[E4300]

Have a decent $78 E7400 from MC. This SLB9Y "R0" stepping Costa Rica chip with a pack date of 3/19/09 is Prime95/OCCT stable at 3.88GHz with default 1.24VID, and 4.2GHz with 1.36V in BIOS + OCCT large mode. Actual load voltage is 40mV lower per CPUz (Abit IP35-E). Peak core temp is 56C with 73F ambient and Big Typhoon cooler. Both temp sensors are good. 1M Super Pi time of 12.296 s.

The temp went up to 69C under OCCT's Linpak. Only run for 1/2 hour cause I don't want to roast this new chip.

This chip runs a little warmer than most other E7400s by about 5-6C. Could be an E8400 reject.

Managed to drop load temp ~4C by removing the heat spreader and replacing the stock thermal compound with AS5.
