Retail E5200 @ 4.317GHz on air result!

[Glow9]

I want to see what this can do under water or LN2 just cause lol

[Omastar]

Never seen a chip that said Costa Rica on the IHS, Great Result... got DICE or LN2?

Costa Rica chips generally don't overclock as well as ones from Malaysia/Philippines. I read that somewhere a long time ago, but I'm sure the difference is negligible (needing slightly more volts for the same OC, for example).

Can you see my coretemp? 39C sir.

I bench in air condition room, ambient 20-22C, Ultra120EX W/Double Fan ~4000RPM & MX-2 Thermal compound.

I don't want you to believe me as long as you can try it.

regarding the average temp all over (rainy season) Thailand @35°, it would be something like very difficult to verify the 39° @ ~ 1.7Vcore @air, especially during SuperPi and other benches are running

sometimes its a lucky moment to touch alt+print and saving screens before getting black screen going concern that torture for the chip........

Thailand 30-35C Yes ,But I bench in air condition room, ambient 20-22C.

so basically this wont be a guaranteed 4.0ghz overclock for a relative n00b like me right? should i spend a bit more for the e7200?

[MajkY]

setup:
ASUS P5Q PRO
E5200 / Noctua NH-U12P
2x 1GB ADATA EE 800+
HDD 640GB WD Caviar
CORSAIR VX450

Question: What is the max reasonable Vcore for 24/7 system?

[stangracin2]

what are your memory settings

4.0GHz is not guaranteed with e7200 either...more like an e8400.
but still, e5200 at 115$(aud) is a nice chip for 3.6GHz. i like. also the 12.5x multi is just too easy.

i don't think 3.6 is gauranteed either more like 3.35-3.4

[WhiteFireDragon]

many people can't get high fsb with these chips on a mobo capable of doing 500+ fsb

[stangracin2]

i'm just now getting to 300 on mine

[ninong]

thanks for your replies

well basically i'm looking for a cheap processor to start with since this is going to be my first time ocing with lga775 (done it with 478,939,AM2 though)..i'm going to get a dfi lp ut p35. i didn't really mean a 'guaranteed' 4ghz OC..i'm looking at something that does 4ghz @ 1.4v or less on a sub $120 processor (i've seen a lot of guys do 4ghz on e7200 @ that voltage). btw i'm talking about cpu-z voltage..so prolly a bit higher when i set it in the bios

[MajkY]

I have problem with booting into windows.
Everytime i set 1.435Vcore+ in bios, my windows wont boot (allways freez at loading screen). And one time i had to reinstal the whole system, that was when i tryed to set 1.5Vcore in bios.... any advice ?
version of bios 1004.
here are pictures of my bios setings

[xdan]

You have to many and too high voltages Probably because E5200 is a 45nm chip is very sensible to high voltages. And P5Q-PRO also is.
1.90 PLL You can burn your chip didn't you read on forum?
At me NB stable voltage is 1.34, 1.36 .
You can also update your bios with a moddes one m1306, m1307 from Ket.
I give you an example
E2140 Fsb 390*8=3120MHz
FSB STRAPP AUTO
RAM= 1040MHZ 5-5-5-5 2T(depends on ram)
Vcore=1.362
NB= 1.36
VTT=AUTO
GTLREF=AUTO
PLL=AUTO
SB =AUTO
SATA V = AUTO
DDR VOlTAGE= 2.3V( A-data 800 EE D9).
From what i've read P5Q-PRO is more stable with low voltages, at high voltages is becoming unstable.
Try now something like this with a FSB 320 FOR E5200. for that i've seen results with 1.392 vcore.
With fsb 320 you will have 4GHZ.

[MajkY]

I have tryed as you say. I can boot now at 1.435Vcore 3800Mhz, but its unstable in Orthos . What V should i increasd ? Ram is on 800Mhz

[xdan]

After how much time errors appear?
E5200 is a 45Nm, you can't boot (even post)with 1.4?
If you run more than 10min is good you don't must change many things.
What bios do you have, try a bios from Ket.
I saw that for some Cpu, that with a mbios worked with a lower voltage at same frequency. (some quads on Deluxe).
And thry with rams on other frequency(divizor)
A strange thing on my P5Q-Pro is that with frequency described on last post, is stable with ram at 1040, but it's not stable with ram on lower at 1003 !
Try another ram frequency , try VTT 1.24, 1.26, 1.28(with these voltages i can run stable at fsb 398 but my rams do errors at 1060+, and Cpu won't boot more than 400fsb so i've prefered to stay on VTT auto and 390FSB)
It's don't worth for an E2140. I will buy soon a E8500 E0.
Another thing is to respect voltage default for Ram . Example: for 800Mhz i put from bios 2.1 for my A-DATA , may be you have, if not put the voltage specified to rams for 800MHZ, don't let on Auto
GOOD LUCK

[MajkY]

i think i found out why i am unable to go higher...

i dll new prime95 and than saw it...one of my core is holding me back
is there any option on how to disable one core ?

[xdan]

You can't "disable a core". I still think that 1.43V is too much for Cpu, mine E2140 becomes unstable at 3120MHZ if i co upper than 1.39.
Another thing Load Line Calibration(LLC) is enable at you?
If not you shoud enable it brings Vdroope muc lower and stability !
At 1.368 voltage with you reach 3.6GHZ, you can't go futher with that settings ? Try to tweak some voltage settings(NB(1.34, 1.36),ETC)
Also a thing from mine , I have freeze moments if i use vtt voltage when Nb is more than 1.32. Another setting stable at me( VTT 1.28, NB 1.24) rest are same as in upper post
No what i can say, more than 4GHZ don't make hopes

[MajkY]

what about GTL? how should i tweak this one ? i totally dont understand this ... x0.64 ...

[xdan]

Mine works only x.67, the highest, other values produce ony instability. I've read that this value is good for 65nm. For your 45nm should be a low value 0.65 or 0.63

[samsonJS]

I've had good luck with cpu gtl at 0.63x, 0.67x or 0.675x depending on the clock. You can try setting fsb termination manually. 1.1-1.4v is a good range, but 1.4 is a bit high and past 1.45v you can permanently damage your cpu.

[Sgt_Strider]

Thanks for the informative post. I'm wondering how well does a E5200 perform on a clock for clock basis with a E8400? For example, let's say that both the E5200 and E8400 were at the same clockspeed, how much of a performane advantage would an E8400 have in games, Photoshop CS3, Winrar, and video and music encodings?

Up to 10%, usually around 5% IIRC.

[Sgt_Strider]

Up to 10%, usually around 5% IIRC.

Are you sure about this?

[xdan]

More than that ,15-20% i guess. From what i know E8400 and E5200 have the same core, 45nm, Intel virtualiztion E5200 does'nt have.
The main diference is the cache which is 6mb for E8xxx and 2mb for E5200/
Anyway this E5200 do a great concurence to E7xxx, and smash with al x2 series from Amd up to X2 6400, an even to triple core
It's seems that Intel realy wants to crush Amd
