E8200 Overclock

post #1 of 11
Thread Starter 
Hey guys, just a couple of questions.

1) What is be the default vcore or this cpu, also, is it alright to leave it at 1.328v running at 3.4 24/7?

2) What temps are acceptible for 24/7 use idle / load?

Thanks

I'd suggest not going over 60C on load, 1.328v is ok, but i hear it can hit 3.8Ghz @1.3v, i'd say try go a little higher and see if you can have the vcore lower, if it doesnt boot with the lower vcore adjust your RAM settings and make sure your PCIE etc is locked down

A voltage increase on your northbridge could help also, to cope with the increased FSB speeds

E8200's VID is 0.85 to 1.36. If you run the cpu at stock speed, 0.85 is lowest voltage. 1.328v should be fine. E8200 has C0 stepping, which has max thermal limit 72.4c so try to keep it low as possible.

At 3.6 at this voltage it will post, but thats it. No stable boot. I took the vcore up to 1.365, and i dont really feel good about going any higher and it was still not stable. On the other hand, i took down the vcore on 3.4 to 1.312v, and it 6min Orthos stable now.

For some reason im getting 68C on load now. I take it thats not good, time to reseat the heatsink...

Adjusting the vcore is just a part of OC, you need to apply proper voltage to ram, NB and SB especially at 3.6G and above. Most importantly, for your chipset, you may unlink the ram so the ram won't run out of max.

NB is @ 1.45, SB @ 1.55, Ram is unlocked running at 800 @ 2.2v as rated on 4-4-4-12. This machine was running OCed with a e6400 before, so most of the other voltages and settings stayed the same, i had to add to the SB voltage for some odd reason to get it stable this time tho. Now im just trying to fine-tune the cpu

22mins Orthos stable now at 1.312, but temp is up to 70, think im gonna reseat it first, then let it orthos.

Thanks for the help

Still running strong. Stress tested it through 48 hours with 64bit Prime95. Never got above that max of 67. It seemed to only occur in the mornings - my machine is near the window and it's facing sunrise which probably did that. 60 seems to be it's full load norm. I'm running Win2k8 64bit. It's been solid as a rock for well over a week now.

It's kinda strange but, I have the same problem too. All sorts of BSOD, lock up at 3.6ghz. Increasing voltages didn't help. That's why I settle for 3.5ghz OC.

That's a nice OC. WoW you're using a $15 cooler too.

tongue.gif E8200 with C0 revision
Have ASUS P5Q3 Deluxe WiFi (16faze DDR3) motherboard
ZALMAN CNPS 9500 cooler with MX4 thermal grease (RPM on 60%) very quiet
The cooler has 6xheatpipe made from cooper completely
HAVE smile.gif good PSU ThermalTake ToughPower 700W (coolish) 88% efficient
with EM & antiStatic protection

THE RAM is CORSAIR VENGEANCE 1600Mhz (CAS 9-9-9-24-100 2T) 1.50v (2x4gb) :cool:later I chose G.SKILL 1333 CAS 7-7-7-21-60
can do even 1500mhz on stock still 1.50v (doing 1267mhz@ 6-6-6-18-60 1.50v)yessir.gif still I have to check error proof how long does it hold?
1133Mhz 5-5-5-18-48 1.50v Gskill

I let the C1E enabled so the CPU drops frequency a bit when not working much. also on 3.2Ghz (not necessary if only gaming is on, works smoother)
The Enchanced Halt State is Disabled becouse Vdrop is ON. (no speedstep)!

Sometimes IF RAM clock is very high just a slightest increase in Vcore is needed very little...

GOT NICE VOLTAGES on stock 2.66Ghz (333x8) with Vdrop Enabled (Voltage drop correction)
RAM 1333Mhz (dropped CAS to 8-8-8-20) 1.50v CORSAIR
1.00625v in BIOS and 0.9950v in windows
temperature in PRIME95 max power test can't reach 46°C (I tested for stability)
(36°C on idle) outside temp is 28°C (IN CORE TEMPS)
CPU INDEX TEMP is 23°C System temp is 38°C

I did O.C. on 3.2Ghz (400x8) with Vdrop and got stable on :
1.14250v in BIOS with DDR3 1600Mhz CAS 9-9-9-24
If I drop RAM to 1200Mhz CAS 7-7-7-18 its still the same speed in benchmark so ratio and timings;
is what can spare northbridge a bit from working. (lower latencies are speed if u don't need 1:1 ratio like for 3DMAX or alike u can win on 4:5)

The original is doing stock on 1.22v in bios 1.76v in Windows without Vdrop on.

NOW something important >>> to make BOTH CORES work the same voltages on some machines have to be rised for approx 0.016v above what PRIME95 can test at stable.
Becouse one core can work less than the other (that's undervolted core (it's dual core CPU so both cores aren't indentical totaly; like clones)
I test this when I run a game and I check with task manager to see performance graphs for both cores. They should work in synch:handlebar more or less. If undervolted one core is not doing enough so. rise Volts more IF)

One more O.C. setup is on 3.05Ghz 380x8 on stable Vcore 1.08750v in BIOS & 1.074v in WIN
COREtemp is min. 35C, max 42˙C power consumption is max 26W for CPU on my motherboard, outside temp 25˙C (RAM 1133 5-5-5-18)
eating 22,50 amps on motherboard
(using CPUID hardware monitor, still can be incorrect with some motherboards if they have reader for IT) I hope my reader is correct. I think yes.SO
I read about E8500 doing 3.66Ghz on 1.12v and using just 31W. So it's close. smile.gif

I use this settings everyday so O.C. isn't hurting the CPU (prolonged life), and I get SUPERPI v1.51 1M on WIN7x64 15.340 and 15.430 in win7x32 same wink.gif CPU eats the same AMPS as at stock!!!

I noticed that a raise of Vcore for 0.08v is making approx.4W more electricity usage
and few °C more heath so it's nice to overclock without making difference from stock usage ....... in heath

On my chipset P45 i have 1.10V at all time
CPU ppl 1.50v
south bridge 1.05v
PCIeX & SATA 1.50v
Termination voltage 1.10v (45microns) and older CPUs use 1.20v (65microns)
VTTs are 0.630 % 0.670 chipset Vtt is 0.630
(these are auto or stock like that and work as INTEL standard is anyway)

POWER SAVING SETUP if U like for a bios profile if u have one free :
300x8 @ 2.41Ghz on Bios VCORE : 0.93750v stable
and temperatures can even rise like >>> idle 34°C maxed load 42°C tongue.gif during summer not winter) This is good setup for only Windows 2D mode.
Still I player Unreal Tournament 2004 on setup and works swell.

So I lowered power consumption and temperature
Prolonged lifespan of CPU and motherboard
Didn't loose any of speed with voltage droping. This CPU its fast have to say. Very power efficient too (I love it just I really wait for 8400 or 8500 so yap will RnR)
I use FOLDING@HOME when I don't do much so CPU is busy and no C1E is needed. LIFE HELPER
I'm sure U can preserve CPU also; not just O.C. grill it.sonic.gif
THE E8200 still has 6Mb cache and its awesome little beast on 45nm die.
This cache is important if u have crossfire etc. comes handy but crossfire sometimes doesn't. lol
6mb is faster than 4mb for I think about 1second in SuperPI approx. I had one before.

Have only 2 profiles in BIOS to SAVE setups (I would need some more smile.gif

ON biggest O.C. 3.62Ghz (450x8) had to rise NB to 1.14 and Vcore to approx 1.28v (didn't use becouse voltage is too high 4 every day use) reduces lifespan still 3.2Ghz is enough for gaming, well at least for most games. I rather buy E8400 or more for that kind of speed.

I noticed that on XPsp3 32bit everything was ok going above 3.2Ghz so I got dissapointed,
Than on Win7 64bit & Win7 32bit I can't even get stable on&above 3.2Ghz its a nightmare on never windows so I guess this CPU has limitations due to safer overcloking I prefer not to raise volts too much; can suck for Ecology like matters puke.gif

I can still hit 411 FSB on WIN7x64 or x32 but thats MAX 3.30Ghz anything else wouldn't run graphic drivers and crash after a while confused.gif. I stick to PCIeX 100Mhz. and PCI is normal always.

Like the 367FSB setting it's compatible the most with PCI(33.3) and PCIeX(100mhz) so > 2.94Ghz on BIOS voltage:1.06125v works DUDE:D SuperPI v.155 1M (16sec) win7x32

REMEMBER to lift voltages for approx. 0.016v IF both cores aren't working pretty much the same (they never work the same still tongue.gif I said pretty much)
It's a noticable difference If U test this can lift up one core to work more.
NOT every CPU is the same so testing is preferable,,,...,,,

proof.gif Have fun grouphug.gifsmil3dbd4e4c2e742.gif next I'll buy E8600 will go nice with DDR3:ninja:
