e7200 @ 4ghz

[Alfizzle]

Right i got sick of overclocking my ****y q8200 so went out and got a e7200

stuck it in computer shoved the fsb right up to 422 with 9.5x multi, memory is at 844mhz.

it boots into windows with these settings:


cpu host freq: 422
pcie freq:100
performance enhance: standard
cpu vcore: 1.36875
cpu termionation: auto
cpu pll: 1.560
cpu referance: auto
cpu referance2: auto
mch core: 1.260v
mch reference: auto
mch/dram reference: auto
ich i/o: auto
ich core: auto
dram voltage: 1.82
dram termination: auto
channel a ref: auto
channel b ref: auto

just need to get it stable enough to run prime, temps are looking high so im going to lap the ihs as its REALY uneaven

any help on tweaking these settings to get it stable would be a great help

Thankyou.

Just need to increase your voltages until it becomes stable, but watch the temperatures. You can also put cpu termination up a little, though don't exceed 1.4v to be safe. What RAM have you got? Are the timings and voltages set correctly?

yeah temps where getting pretty high so im currently lapping the ihs

The timings and voltage for ram is set correctly @ 5.5.5.15 rated at 1.8-1.9 volts, its geil black dragon memory, not the best overclocker but ive had it running at 900mhz before stable at 2.0v.

what would you consider the highest "safe" setting to be for each option listed above?

Thanks for your help

hitting the 4ghz mark is definatly possible with this chip,but not in my rig at the moment.

temps where reaching 70-74 at full load and prime 95 wasnt stable so i was to scared to up the vcore.

even lapping the ihs hasnt solved anything, im going to reseat the h50 and add another fan to do push pull, plus properly lapp the cpu to true flat and see where that gets me..

off to the shed to find me some more sandpaper, and my nice glass sheet

just to add its stable in prime95 at 3.16ghz 1.168vcore max temp 51c.. so not too shabby, if i cant reach 4ghz i would like at least 3.6

I'm no expert but these are the max voltages which I would consider safe, provided that your temps are under control. some may not agree. remember all overclocking will reduce the life of your components.

cpu vcore: 1.36875 max 1.4v (bios),
cpu termionation: auto 1.4v
cpu pll: 1.560 fine at stock 1.5v
cpu referance: auto
cpu referance2: auto
mch core: 1.260v 1.3v
mch reference: auto
mch/dram reference: auto
ich i/o: auto ich not relevant. leave alone
ich core: auto
dram voltage: 1.82 depends on manufacturer
dram termination: auto
channel a ref: auto
channel b ref: auto

reference voltages are calculated as a percentage of core (i think). i wouldn't mess with it unless you know waht you are doing.
