I hope that this is not a duplicating topic since no real discussion on intel E7200 although there is one on E8XXX peryn series..

The stock E7200 is actually a budget processor to the E8XXX series & having 1/2 of what those E8XXX series having..such as 3MB L2 Cache compare to 6MB L2. The following is the stock specs of this processor:

Code name = Woftdale. Core speed=2533Mhz, Mutiplier=9.5, Bus speed=266mhz, rated FSB=1066Mhz . Stock Vista score is at 5.4.

For my overclocking experience & history, I started wth a low budget MOBO Asrock Woftdale (Intel945 chipset) and it's such a dissapointement because the highest I can go is up to 310X9.5 or 2945Mhz. As a OC noob at that point of time, instead of changing the MOBO, I upgraded the HDF to Xigmatek HDT964. I was happy wth the tremendous reduction in the Temp but not OC!! It still no good & I can't bypass the 310X9.5 barrier!!

No choice but to upgrade to P35 MOBO which I got it from a forumer here...ABit IP35P & that's how I feel that I should post the result here as well since I hv posted my OC experiences in hardwarezone singapore here: http://forums.hardwarezone.com.sg/showthre...=1950140&page=4

Nevertheless here is my latest at 3800Mhz Vcore 1.275V (Avg load temp 55C) & will continue further & targeting 4000Mhz or even 4500Mhz soon...

erm think this can join intel penryn thread..nonid to make new thread

Sorry moderator for re-opening this topic again...but the other thread availbale is only discussing on E8XXX series which is entirely different from E7XXX series which is a budget processor

Even Hardwarzone Singapore is having a separate Topic on E7200 ....Nevetheless I hope moderator to rethink because I do need feedback from E7200 users & not those E8200 or E8400 users...

hehe sorry bout it coz jus gv advise since its included in penryn fam..C2D even differ type of e84,e82 or e85..even xeon n C2Q discuss there yea myb better for mod to clear it

already purchase a E7200 too
awaiting mobo

man....already got this topic ar??
kinda want to get this E7200..price cheap....same 45nm...just the cache is low....
so how far this baby can go?

My above posting is the best I can go...i.e 3800Mhz on 1.3V Vcore. Further than this system unstable

It's on Abit IP35P Mobo & Xigmatek HDT SD964 HSF - Fantastic cooler ...on high load, temp maintained at avg 55C (Max62C) only & idle temp at 44C

Wondering anyone getting higher than 3800Mhz.. ..If yes what is the voltage? I tried up the voltage to 1.35V but stil failed..

I reduced further the Vcore to 1.28V (BIOS setting=1.255V) and still stable at 3800Mhz. Temp further redcuced to 41C idle.

To get 4000Ghz (421X9..5)...Probably will try to increase the Vcore to 1.4V instead .by then my CPU vista score probbly touching the max of 5.9

Your CPU vista score will explode with that core clock ...

omg...very nice proc....btw, waht is ur batch ar?

Naahhh....just Vista score..nothing to do wth explosion.... ..Even at 3800Mhz..idel temp is at above....Load temp =55C probably by reducing VCORE, load temp probably 52C...I am predicting at 4000Mhz & 1.4V, probably temp will be at the range of 48C & load temp 65C...

Yesterday failed..but I know someone in Singapore did it by reducing mutiplier to 8 & FSB to 500Mhz!! Vcore if I'm not mistaken..1.4V+...

Nevertheless...at 3500Mhz & above, the passmark CPU benchmark tool dun looks great anymore wth small number increment as u can see from the 1st post


Here is the benchmark website..intereting one

http://www.cpubenchmark.net/

This is better than conroe

On stock, the reviewa at those OC websites rated this 1/2 cooked E8XXX series as in between E4700 & E6700 processors..but from this website:
http://www.cpubenchmark.net/high_end_cpus.html

The stock performance is actually better than the top conroe (E6750) which is running on 4MB L2 cache compare wth the 3MB L2 of E7200 & it's ~RM150 cheaper than conroe E6750 & ~RM200 cheaper than E8400..

On oveclock stage..This is the one I can't believe..see the chart below:
http://www.cpubenchmark.net/overclocked_cpus.html

It's even higher than E8400 the fully cooked Woftdale... Nevertheless.I dun really believe that because at 3700Mhz, I only managed to score 2283 only (refer 1st posting) which is abit higher than E8200 on overclocked stage

OK latest on my overclock story...Although I'm able to run Vista core & Passmark score on 3800Mhz - but this Morning, I encountered cmos checksum error.. ..so currently running at 3700Mhz only which I feel it's faster than running at 3800Mhz..

im going to allow this thread but if i feel its of no use im sorry, im going to close it down
ive seen posts like"wah nice proc" and all that here.
spam has to stop.

thanks

stimix, how high the FSB cna go, have u try it ?? may be u could do 500mhz x8

Darkshythe so generous, hehe boss any intention of trying this new proc??

i have tried mine on 510 fsb before stable.....i think if really tweak can go higher...will try to upload some ss when free...

Your processor not good 510x9.5 i think is impossible

wats the diff between 8 series and 7 series?.. 8 series shud oc much better right?..

U can check/compare the only extensive review of this processor here:

http://www.xbitlabs.com/articles/cpu/displ...uo-e7200_2.html

As said earlier, it is almost the same tech as E8xxx series except having 1/2 the L2 Cache of E8 series processore, no VT & running on 1066 bus frequency compare to 1333 on E8xxx..It suppose to the budget processor to E8 series and having better than earlier conroe E4700 of even better than E6600. (Cheaper too )

Added on June 8, 2008, 3:39 pmImpossible-leh....can't get anything higher than 400X9.5 ..Maybe MOBO limitation or even cheap Mem RAM.. ..hehe..moderator so kind oledi..allowing the only topic on E7 series... Hope no spamming too..

---

Added on June 8, 2008, 3:51 pmWell, it's a small brother to E8xxx series..what u expect.. ..Read thgis X-bit lab conclusion:

ask pak google n u will see somebody did with 1.9v......

n i didnt say i did it on 9.5 multiplier also.... i just say max fsb....

1.9v bro dry ice run?

any chance to go more?

3MB cache and 6MB cache difference

I managed to boot-up after increasing the FSB to 421X9.5 or suppose to be 3900Mhz & increasing the Vcore to 1.39V....,man idle temp shoot upt to 48-52C & load temp no joke...about 59-68C!!

However not happy wth the overall result!! CPUz show that my core speed actually much lower..at ~1600Mhz only & boot-up time tremendously reduced... ..Even if I reduced the multiplier..no help..I think to stay satble at 3800Mhz only

try not to reduce multipliers, play with default multipliers as much as you can unless its an extreme processor..

erm...this is the best i can do though....not pro at tweaking

have u tried memset bro.. by the way, ill join this gang soon the e7 gang

erm...why memset?

don really get ur point there.....

well memset is pretty neat with tweaking the rams..

Haiz...right now keep on having CMOS check sum error msg during booting & all my OC, returned to original speed... and that even I OC as low as 3600Mhz....haizz...dunno which setting that is in error....

hye ts may i know what setting u put in abit mobo to achieve 3.8?
i plan to buy e7200 pair with offlimit or any1 can suggest me other mobo?
cuz my fren abit restart twice la.....

My setting @3800mhz:

Maintained the 9.5 mutiplier
increase FSB to 400Mhz
Increase vcore to 1.255V (or more but wathc out on increasing temp..For those intended to OC>3000Mhz.I think should change HSF)
Other voltages -maintained
DDR set at 1:1 (5-5-5-15)

Disable EIST & ....(Aiyah let me chk later)

EIST and C1E

I came across that Intel going to release new stepping E0 for 8k series processor. Not sure will 7k series will get "benefited" or not. Anyone know?

diff between 8 series and 7 series like darkshyte says is the CACHE..the bigger the cache,the bigger the potential to OC,but the bigger the cache with no OC is bloody hell USELESS..just like a 6 lanes highway with 1 car..

btw i just bought E7200,have to join this clan haha

are u serious about this?

yeah i also find that arguement not valid..

" the bigger the cache the bigger potential to OC"
usually its the other way around..

for example?

i would rather rephrase that the bigger the cache the chances of getting a good run on superpi is better. In OC, the cache doesnt matter because you are manipulating the clock cycles and not the registers in the CPU. The ability for it to run on high speeds depends on the stepping and also the quality of the silicon wafer the proc companies use.

paiseh..this terminology should be use for HyperTransport not CACHE... sorry sorry A bigger cache only allows the CPU to store more data at any given time and reduces the number of times it has to go back to the system memory to look for data..


Think of the data paths that link all those things together as highways. If you try to fit too many cars down the highway, you get a traffic jam and some cars have to wait before they can get through. HyperTransport puts more lanes in the highway so more cars can flow through it. If you have two lanes, but only one car is going down the highway, adding a third lane won't make that car go faster. If you have a few thousand cars, but only two lanes, adding a third lane would make the flow move faster. I used wrong terminology...paiseh..

the stepping will affect the oc capabilities. i dun think intel will produce E0 stepping for e7xxx serier, even C0 on e7xxx also quite imposible ~ mayb some bad batch fr e8xxx C0 will use to produce e7xxx.. lolx

mine batch Q815A471 VID 1.1V with Biostar Tpower I45

Maxxx boots......1.7vcore watercool

wau rlhc17,suicide clock..
is your vdim at 2.2v?

Try 500x9.5

cpu v1.1x
past sp2004 @3.3g
i have no try add more voltage..
as i try it, it can be go to 3.6G @ v1.1xx, but very unstable...

How much your vDimm??
As i can see, your ram SPD is 800 @ CAS6.

-pWs-

guys which is better wolfdale or yorkfield?

tq

Depend on your usage.

Wolfdale = 45nm Dual
Yorkfield = 45nm Quad

-pWs-

E7200 produce greater heat compare to my E8200. Can even hit up to 91C on TT big water.

got my mobo (MSI P35 NEO3)
still on tweaking
