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...

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...

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

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/

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..

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:

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

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....

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)

WHoaaa..long time din log-in here and noticed someone touching 4200mhz oledi...crazy...dry ice huh

My max is 3800Mhz and not dare to go further. I did when further few times on my old MOBO and ended up in ICU...

Whoaaa...ur core temp @58C is alarming high....better change to a better HSF b4 the MOBO grilled..
