Official Core 2 Duo E7200 thread

[Gr1mR34p3r]

Why don't you try to find max FSB, I only see 400-500 here, lowest with 8x multi.

That's the VID , look closely... not Vcore

What's the difference?

[hawk999]

here's mine hehehe

[FattyTW]

not very idea with that voltage with that speed

[hawk999]

not very idea with that voltage with that speed

y???

i'm using Gigabyte ep45-DS3R i have difficulty on overclockin it

[fragmasterMax]

no worries. im getting a e8500 and another e7200 in a few days i REALLY want to break into the 9's on superpi 1m on this processor. now that i got a few tips i think its very do-able.

these cpu's LOVE the cold btw.

i have a 3dmark06 @ 4.75ghz if anyone is interested in seeing the screen shot. 20k

niiiiiiiiiiiiiiiiiiiiiiiiiiiiiice.
what videocards are you running to hit 20k?

[kapster]

For anyone thats upgraded from an E6600 or similar, do these E7200's run any hotter?

My E6600 @ default voltage @ 3.0ghz idled at 30C, load of 40C

With this E7200 its idle of 32C and load of 42C.

This is with Real Temp, latest ver.

Im on water with a D-Tek Fuzion. Also I live in florida, ambient is pretty high, 82F or so.

Has anyone experienced a FSB wall at around 370 fsb? What settings other than NB voltage, CPU voltage, memory voltage, and FSB strap can help get past this? My e7200 will run 3.467 (9.5x365) ghz, but I would like to drop the multiplier and run it at 400 fsb.

I am using the following hardware:

ASUS P5Q Pro
E7200
2x1GB OCZ Platinum Rev. 2 DDR800

What voltages (cpu,NB) were you trying? ...

FSB Frequency: 400
PCI-E Frequency: 101
DRAM Timing Control: MANUAL
5-5-5-15

DRAM Static Read Control: Disabled
DRAM Read Training: AUTO

AI Clock Twister: AUTO
AI Transaction Booster: AUTO

Load Line Calibration: Enabled
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled

CPU Features: all Disabled

I have tried up to 1.4 on both the cpu and NB. The NB is passively cooled and I am using air cooling with a Ultra 120 on the cpu so I don't want to go much higher on either of those. I have used the same settings you are listing below, and have also tried using a FSB strap of 400 as opposed to auto. I guess it's possible I just got a poor chip for overclocking. I have heard that some e7200s take around 1.45v to hit 4ghz and higher. For gaming with a single HD4850 going higher than 9.5x333 (3.16 ghz) probably doesn't give much a of a performance increase anyways, and I can run that speed at stock voltage.

I had hit a wall at 370FSB and higher on the evga 750i FTW motherboard. This issue was resolved later on with a BIOS upgrade.

Also I got a Q81 batch and I need 1.488V to hit 4.11ghz. Seems like a bad overclocker

[hawk999]

guys i have a problem on stabling my e7200 on a gigabyte ep45-DS3R

i turn off all C1E EIST every kind of calibration that the board have..

hmmm

i must ko 1.45v to stable a e7200 on 3.6ghz

[blizzisu]

From what I have read on some other boards, and from a few posts here, some of the e7200s take relatively high voltages (1.45+) to hit the 3.6 - 4.0+ ghz range. I guess that is what you get when you buy a budget processor. It's all the luck of the draw.

It's true, in my case though. I can OC my E7200 to 3.0Ghz with just AUTO value of the voltage(or 1.28v in BIOS actually) with my budget mobo Asus P5K-SE very easy. In my case a 365 fsb is the highest value with nominal voltage used, 370 fsb and up-the vcore needed is i think is too high.

First factor i had in mind could be my mobo, it had an insane vdroop, i think i'm going to mod it. The second factor could be my E7200, maybe i've got a bad clocking chip here, btw the FPO/batch is #: Q815A472.

Right now i'm running at 3.467Ghz at 1.37v in BIOS, Cpu-Z and OCCT both reads the voltage at 1.344. My mobo vdroops during OCCT tests, the voltage falls down to a mere 1.3v only-vdroops are really annoying. I will chase 3.6Ghz or higher once i'm done vdroop modding my mobo.

[hawk999]

btw is it my mobo or proc??

proc batch Q815A539

???

[labs23]

^ I'm afraid the problem is your proc., i've seen lot of bad clocker E7200 chips around here, which sadly, includes mine too. You've got yourself a good mobo, its already a P45.

[hawk999]

^ yep its p45 but it has a large vdrop that gaves me headache

imagine 1.45v on bios in windows 1.37v? or 1.408v?

[thehinge1]

For the record on the 'official' E7200 thread:
Cpu Frequency with this setup is 3.85GHz, SuperPI 1M times around 13.4 sec - I think very low 13's or even lower is possible once I get the memory fully sorted out. The chip is stable to about 3.944 with same voltage shown below on both P5K and P5Q-E.

[kanguru]

Hi,

Do you guys think that 1.408 on cpu-z is too much for this cpu? (I setted around 1.45 V at bios)
It looks stable at 3.7 GHz with this voltage, and only reaches 52ºC (core) @ 100% load...

[hawk999]

hmmm guys i read lot of forums they said that the 45nmn limited voltage is 1.45v...is in the bios that to go far from 1.45v or in windows?? i wanna make think clear out thinks

[gwai lo]

Care to rephrase?

If you mean to ask whether 1.45v is a BIOS limit, it isn't. Many people are going with Intel's spec and trying to keep around 1.4v or under for 24/7 use. If you're asking whether there's a difference between BIOS vcore values and what the vcore is in Windows, yes there's a difference. What you set isn't what the chip actually gets.

I got an Q815A300 and it looks like I'm topping out at 405×9.5 Board is an Asus P5E-VM HDMI, might try dropping the 0.5 and pushing the FSB higher. Looks like a lot of the better overclockers were <Q810 ish.

[hawk999]

^ ic tnx alot i don't want to push my proc anymore i'm fine w/ 3.4ghz 1.38v@bios

[Leeghoofd]

FSB Frequency: 550
DRAM Frequency: 1000 (BIOS says DDR2-1102)

Think bios is correct you cannot run 550FSB and 1000mhz it has to be at least 1:1 divider on ya mobo...

[Shrekogre]

heres mine

[blizzisu]

heres mine

Nice results. have you tried 7.5x533? for 4.0ghz?

[stingush]

i did
