E7200 Overclock

[Absolution75]

I'm currently having some trouble overclocking my E7200.

It seems like I can't get enough speed out of the voltage I have to run.

It seems like the VID is a lot higher than what I've seen on a lot of forums (1.225V).

Specs:
Intel E7200
EVGA 680i (Latest bios)
4GB OCZ DDR2
Thermalright HR-90 (The extreme-120 doesn't fit in my case =()

Bios Settings:
Clock: 3562MHz (9.5 x 375)
FSB: 375MHz (1500MHz effective)
Divider: Linked 3:4
Memory Frequency 500MHz (1000MHz effective) @ 2.1250V
Memory Timings: 5-5-5-15 @ 2T
CPU Voltage In Bios: 1.3850V
CPU Voltage in windows (idle): 1.368V
CPU Voltage in windows(load): 1.344V
All other voltages set to auto.

Idle temp: 40-44C
Load: 63-65C

Prime 95 + CoreTemp + CPUZ:

Any lower voltages will make prime95 fail, anything higher tends to not improve my speed at all. (I've yet to pass 1.39 in BIOS, I suppose it wouldn't be that high in windows).

Is there a relation between a high CPU VID and a high voltage tolerance? Should I crank up the voltage and try to increase speed?

Any suggestions?

Usually, the higher the VID, the less chance of a good overclock. But not always, emphasis on the 'usually'. The VID on my chip is 1.075v, I only need 1.296v to run at 3.8. So this would prove the rule.

However, you're approaching the safe voltage limit, I'd be tempted to try a little more voltage to get to 3.6 and call it a day, it's plenty fast for that 8800GT you have.

Rule of thumb with these chips is not to go over 1.4v.


EDIT: I'm trying hard to work out that RAM frequency and the divider you may or may not be using, but it's late here and my brains are tired. But I'm assuming you've clocked your RAM right down to ascertain your chip's limits, just to take it out of the equation? It's looking to me like you haven't and are running it slightly over spec, but just wanting confirmation from yourself on that one, just in case I'm completely off base.

Hi there, I also got a E7200 that has a huge VID of 1.2125v. This chip can do about 3.6@1.3525v/BIOS is about it. Any higher I would have a temp problem. My chip also don't seem to benefit much from higher vloltages, I guess just one of the lesser OC chips out there. But I can see you could do about 3.5/3.6 with yours, that's pretty fast.

I actually haven't tried that with this chip. I used to run my E6600 at about this speed. I'll drop the divider to 1:1 and see if I can get a little more out of it.

Also, updated my sig (no longer a 8800GT).


Thanks btw

Your E7200 overclocks terrible. I guess you could get more out of it, but you'd have to increase the voltage a lot risking to kill the chip.

And you upgraded from 8800 GT to 9800GTX? Why? That's not much of an upgrade at all.

Stepup, I thought I mas as well use it, it was only like $50. It will probably ebay better too.

For 50$ it's a good upgrade.

two things: you can't fit the TRUE in your case-> your temps. I don't think you're getting good overclocks because of your temperatures. Try opening the case, or exposing it to much cooler air, and see if you can reach higher clocks... if your systems ability to expel heat is an issue, it'll only become more pronounced when you introduce more voltage. I'd bet you couldn't get to 3.2GHz on stock intel HSF... for the same reason. Most of the time, the limiting factor in the thermal process is the heatsink, but yours is good- so it is probably your case/ system configuration. If your temps are really bad, you might set off internal throttling- but idk much about that

you don't have an intel chipset, so I don't see the memory ratio as a factor

you still have about 12C headroom and about .06 volts left to push. go for it.
