Official Core 2 Duo E7200 thread

Ok, i finally took off the IHS, and bolted on my d-tek fuzion.

Very dissapointed with the results, on idle i got 33 degrees, but under load it shot up to about 85 or so (using linpack)

The funny thing is that as soon as I stop the test, it jumps straight down from 85 to 33. And when i say straight, its literally 85 -> 33, in the blink of an eye.

I checked the contact and the thermal past imprint was perfect. I also tried wiggling about the block while linpack was running, but without any change to the temps whatsoever.

Hi all,

want to know if there's also someone with my problem.
got two E7200 that don't pass 3145ghz with v1.3625 on GA-EP35-DS3 F3 bios and Neo2-fr 1.97 bios, I get same OC on both boards. Used all multi. from 6x to 9.5x

can go higher with high voltage.

I'm not new to OC, I been overclocking E2000, E4000, E6000.

another thing I notice is that temps on cores are 7° diference core0 = 52° core1 = 60° 100% orthos, prime95.
other c2d are always same temp. on load.

could it be bad chips??
don't have the batch right now, gonna check it and post later.

bro we have a same problem.. what batch is your 7200??

because mine is 1.45vcore 1.22VTT 1.20V NBcore on a ep45-DS3R gigacrap :(

lol

Ok, screwed the parts together, although I'm still waiting for the PSU, now using ye old 400W NoName crap... Oh, the VID voltage: 1.1V. No testing now, because I really don't wanna stress this PSU. :p:

what PSU did you buy??

:)

A OCZ StealthXStream 600W, really hope, that I will get it before september. :/

nice PSU

i'm planning 2 buy PSU Silverstone DA750

@topic

BTW guys is this a good setup on the bios?

because mine is 1.45vcore 1.22VTT 1.20V NBcore on a ep45-DS3R gigacrap

vdrop 2 1.37v

So the newer batches of E7200s don't overclock as well? Hm...

don't know that but, I bought them like 2 weeks ago.
I have the boxes in my office, tomorrow I will post the batch...

maybe...i'm so sick my problems is it my board or my chip has a bad overclocking capability :D

glad I got mine when i did. im sure i could get it to 4.0ghz when i get some more fans in my case.

Well, they pretty much all have high VIDs... I wonder if they'll release an EO stepping for the E7200, like they are planning for the upcoming Ex00's...

Duh, of course I couldn't refuse to test the CPU. :p: Didn't search for max values like max FSB or max clock, but did some Super Pi 1M runs.
Best so far:

here is my batch: E7200 Q743B016 good or bad??

I made a shim out of several sheets of paper, with a hole cut in the middle.

In retrospect i wouldn't have done it, despite the contact being perfect i still got pretty much the same temperatures, and the water in the loop was at ambient temps. There is something wierd going on with the temperature sensors in these chips.

I would advise people to look for what is in bold to get a decent chip. From what I have seen, all the really high OC chips are SLAVN with A after the build date.

Arent all E7200's SLAVN?

huhuhuhu

my e7200@ 3.6ghz

Vcore 1.45v
NB 1.36v
VTT 1.22v
424x8.5 it was stable before but now it was not stable :confused:

is it possible if your NB or CPU is getting hot can cause a reboot system?

temps:
NB 29-31 idle 50-55 load degree
CPU 30-32 idle 51-55 load

tnx

I ended up having to leave mine at 3264mhz on stock everything. Stinkin motherboard and its lack of PCIE lock. 3.8 tests as 100% stable but I dont like running my poor 4850 with 119 PCIE speed. I have the bios page for it bookmarked and I check it every day lol. Also sent biostar two fussy emails and got a reply back that they are working on it.

I guess this is what I get for buying a cheap motherboard... I finally get a good chip and I happen to get a weak motherboard UGG!!! I never get good chips! I know this lil sucker would hit 4+ghz at sub 1.3vcore!!

guys can u help me about this?? :confused:

hawk999 whats your batch??

mine is the same, was stable 425 fsb but now it cannot pass 370 fsb.
I think non OC chips have B in the batch, like mine. -Q743B016-

Q815A539

i think the prob is my board gigabyte has a DES they called but it sucks

K guys I have had this chip for a few months and love it, Have had it in a msi p35 ne02FR, asus maximus extreme, and asus p5Q3 dlx, and every one yeilded close to the same results. furthest was on the maximus extreme at 4.6ghz with 1.55v TEC cooling. I think I may know what alot of you guys overclocking prob are that are having troubles with abouve 3.2/3.4 ish. I see your posts and all have the same setting basically, what you need to do is rais the nb volts to 1.5v and VTT or VFSB (depending on the board but they are the same setting) to 1.45 and cpu vcore set to 1.4v and those babies will fly, thats been the general rule for all 3 of my boards , give it a shot wors case it wont work and you gained nothing.

Oh BTW:
E7200 SLAVN
VID 1.150V
FPO/BATCH Q815A358
packed 06/06/08

philbrown23, done that and didn't work, raise nb and FSB to +0.3v.
I think that is my cpu cause before this board i had a Neo2-fr with same results. (exactly the same)

i tired of my e7200 to reach 3.6ghz :(

Why so many problems OC-ing e7200????
I still have a good'ole trusty DS3 (965 chipset?), and have me 7200 running at 3.94Ghz with 1.325Vcore.... I'm not even pushing for higher, cuz it wont matter much for me as I play COD2, 4 and I'm limited by my AIW1900 card.... But I
m sure I could reach 4Ghz with higher Vcore easy...

I see many users having problems with e7200 last weeks... OC only to 3.3-3.5 GHz with high voltages and high temps (45-55C) in idle and default, too... There is no new revision (I think) , but a few of them have cpu with "B" instead of "A" in FPO number ... I had e7200 and no problem to get 4GHz stable with 1.4V, so I don´t understand what is happening :confused:

I check two E7200 with two different boards and get same OC 355x9 v1.375 bios with vdroop v1.33.
My cpu have B instead of A.
I'm also confused.
I think we are getting bad chips.

the B's are better chips then the A's man, could you guys that are having problems post up pics of your bios or list all options in the overclocking section, I'll be able to help more that way. Also my 3 day old E7300 died today while under DICE but before that it clocked horrible unless it was at the 9.5 multi then it still clocked worse then the 7200 so just FYI.

who has a e7200 Batch w/ A that can reach 3.6+ higher at low voltage?

I already don´t have my e7200 I sold it... but I remember it was "A" and I need to give 1.24V on vCPU for 3.6GHz and 1.328V for 3.8GHz to get it stable...

i think i need to change my board

I have a E7200 with the A-batch. Was benching some stuff at about 4GHz with 1.36VCore. Here's a SuperPi 1M run for example.

I bought E7200 and P5Q-E motherboard and I tried overclocking it a bit... I raised the FSB from 266 to 333 (3.16Ghz on cpu), but I also had to raise the voltage up to 1.25 so that the CPU was prime95 stable but i noticed two things. Prime95 always crashes on the Core#1, #0 works fine even at 1.18V. And the other thing, when idle, Core temp reports temperatures 32°C and 20°C for core#1 and #0. What could be the cause of that difference in temperatures? When both cores are under load the temperature is almost equal max 1° difference. Do I have a bad chip or maybe there is just bad thermal junction between die and heatspreader?

It is an SLAVN, and batch A. VID 1.15V

Only 4500mhz suicide shot on water :(
My watercooling is far from optimal because my Apogee GT is not mounted tight enough (stupid screws).
I did some superpi testing @ 4380mhz and the cpu did go over 100c :shocked:
I had only one hour to test this cpu so have no idea what voltage this cpu needs for 4ghz stable.

Very simple overclock. Just bumped up the vcore to 1.2 and was set to go. No more for tonight(or this morning :D)

Oh yeah, batch is a Q811A257 1.1 Vid. Motherboard is a DFI DK X38. Its water cooled.

Got 4.0 on 1.2volts, is that a good batch?

I think so.
Check mine a few post above. That one couldn't do 4.0ghz with less then 1.29v.

Looks like I got lucky then. :) I'm afraid to do more, dont wanna fry it. Max fsb of the mobo is only 430 though, so I dont think the chip will fry before then. :P

So, I am tryin to upgrade my system.
I am pondering between a E5200 or the E7200. I know the rough performance difference between the 2, price and OCability is the main thing for me.
My goal will be as close to 4ghz possible cooled by tuniq tower 120 with the cpu I pick.
I know the e5200 is quite new and people and reviews say mixed thing about its OC capabilities. it seems its capable of 4ghz but at higher voltages than air would like.
The e7200, I have learned from this thread, is highly overclockable the older cpu's or the ones that contain A in the stepping code and are...SLAVN or whatever(are all of them that?) the A is the biggest thing I remember reading...those yeild amazing oc's around decent voltages...like 3.8-4ghz @ 1.4v or lower right???
The B ones are struggling at 3.4ghz and higher is what Im reading from this thread.
Well, it just so happens in my computer store I work at we have one E7200 in stock and its a A batch or week 0813....Do you guys think that one will be awesome and worth it over a random e5200?

I will be attempting this on the biostar I45 board...do you think thats good to oc these chips with?
Thanks

If you want 4ghz for sure then get a used e8400 C0 that is proven OR get a newer e8400 e0 that goes for $139-149 on sale. The vcore for the most part seems high on both the e7200 and e5200's.

E7200 batch Q813A720 here. 3.4Ghz (400 x 8.5) on air (Scythe Infinity) failed orthos after 9 hours, vCore = 1.275, board is an Asus P5Q Pro. Now trying with 1.2875 vCore, though I have a hunch most of you guys are easier to declare something 'stable'?

I find temps are quite high on this chip, generally around 60 degrees, maximum peaks at 67!

But I'd probably wait for an e0 at $150 on sale sooner or later though.

zlojack has a 4.2ghz e8400 (c0) 1.36v for sale for $160 shipped in the for sale section.

QFT, I'm getting sick of Speedfan overrating my E7200's temps ...

Got what I guess is a final overclock on my chip since 4.0ghz takes a hair over 1.3vcore :( Not that I have a problem with giving it more voltage, it just doesnt feel like .1 vcore for 200mhz is worth it.

1.15 I believe, I will have to check when I get home from work though.

Because my "awesome" P5B-E has a such a "low" Vdroop, and because Asus engineers were too "brilliant" not to allow manual Vcore adjustments with Penryns, it is always at AUTO setting and running at 1.45V in BIOS (1.1 VID + 0.35V) and I can get to 3.85GHz IntelBurnTest stable for 1 hour, and at that screaming load, it runs at only 1.336V (which is an amazing 0.164V Vdroop). Bastard runs at close to 85C in IBT :D

Result is that 3.85GHz (406x9.5) at 1.336V full load. 1.392V idle. (Edit: Actually it is 1.328V in IBT. The mother of all VDroops :-O)

http://i177.photobucket.com/albums/w...ackaging_2.jpg

OMG guys! I did the VDroop pencil mod and now 1.375V (in BIOS and 1.376V in CPU-Z under full load = 0V VDroop :D) and 3.97GHz (418x9.5) Ran 10 passes of IBT and passed. 4.006GHz wasn't stable :*(

http://i177.photobucket.com/albums/w.../sshot-2-6.jpg

Hi guys, first post on the forum (and a great one it is too!) :up:

I hate to bump a thread that hasn't been touched in so long but my problem is incredibly relevant to what has already been discussed on here (and it is named "official" after all!).

I noticed someone earlier in the thread mentioned overclocking the E7200 processor with the Gigabyte GA-73PVM-S2H motherboard. This is the same motherboard I have but I am having some real problems overclocking the processor past 3.00GHz.

I'll admit, I'm a total newbie when it comes to overclocking but I've been reading various threads and articles on how to do it. Still not 100% clued up though.

To the point anyway - I've managed to overclock to 3.00GHz at 1.200V stable, testing with Prime95 (blend) and memtest. FSB is 316 and multiplier is 9.5. If I try and bring it over this I immediately have problems - I ramped the FSB upto 333 and even a voltage of 1.300 won't make it stable (Prime95 crashes within a couple of minutes).

I'm reluctant to bring it up any further, as I've heard people have overclocked this processor to 3.2GHz easily whilst still using stock voltages. Why am I having such difficulty?

I'm currently using 2 x 2GB G-Skill PC6400 (800MHz, 1.8V). I know it has been mentioned elsewhere one of the big let-downs with this motherboard is it won't let you alter RAM voltage in BIOS (only clock speed). Is this where my problem lies?

If any more information is needed about my system just say so! :)

Many thanks!

***EDIT***

Strangely enough, I applied the BSEL mod today when installing a new cooler, and now it is running fine at 333FSB with a multiplier of 9.5 to give 3.16GHz stable at the default voltage! How weird is that!? I'll try overclocking the now-modded chip and see where it gets me.
