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
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)
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
CORSAIR1.00625v 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.
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
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
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.
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
ON biggest O.C. 3.62
Ghz (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
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
. 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
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,,,...,,,
next I'll buy E8600 will go nice with DDR3:ninja:Edited by XRC - 11/4/11 at 6:13am
