E2140 overclocking!

paradigm · 15 Jul 2007 at 13:16

Got me an E2140 as a temporary stop-gap until the price-cuts hit the top end CPUs, but thought that 1.6GHz was a little weedy, currently at:

This is on an Abit IP35-PRO, with 2GB of OCZ PC8500 5-5-5-15, and currently on the stock intel aircooling HSF (will go vapo or possibly water when I upgrade CPU).

Scratch the above, now at 3.2GHz. What a chip for £50

Yeah, all off the stock cooler so far, I have a vapo sat here, but I'm waiting for a socket kit to arrive before I can use it

Dunno if it has anymore left in it, but we shall see

Currently benchmarks higher than a C2D X6800, so I think I got pretty good bang for my buck

3300MHz

Best bang for buck CPU ever?

Got to be close hasn't it, takes me back to my Athlon XP 1600+ days.

EDIT: Yay, i'm still in your sig

nice clock but how stable is it? Have you ran 8 hours of orthos?

No, I haven't. I'm simply seeing what the ABSOLUTE maximum 1M SuperPi stable is, then when I've found that I will work on longetivity.

Give me till next weekend and I'll have the maximum 24hr Orthos stable clock for this chip

Currently my maximum 1M SuperPi run is at 3368MHz, but I'm having problems with my RAID array at this bus speed, CPU seems to still have more in it.

paradigm · 16 Jul 2007 at 16:56

Well thats 3GHz tested on Orthos for 18 hours, going to move on to 3.1GHz overnight tonight

paradigm · 16 Jul 2007 at 18:36

Mines now backed off to 1.4v (for the orthos test) seems burning it in has done wonders

Vapo fitting kit should arrive soon, then i'll give this chip a thrashing

what are your temps like GT?

Mine are at about 50 idle and goes up to about 70-72 on TAT 100% LOAD, luckily it never goes above 67/68 on orthos load

50 idle?

Mine idles at 32ºc :confused:

paradigm · 16 Jul 2007 at 20:53

What thermal compound are you guys using, are you sure they are seated properly, and what ambient temps do you have?

Mine runs damn cold tbh, ambient is currently 26ºc, and idle (7-12% load) is at 29ºc :confused:

Yes I am mate, although you do have to set certain options in the BIOS first (like memory dividers/CPU multiplier), but now I have my FSB/DRAM strap where I want it, and the CPU multiplier set at the value I want, I do all my voltage and bus speed increases in uGuru in windows (vista x64).

Fantastic board IMO, best upgrade I've made in years.

paradigm · 17 Jul 2007 at 20:35

I think I may have hit the FSB limit of the chip

Can't seem to get stable at all beyond 420MHz FSB, its not the RAM as it has been up to 595MHz with the next strap set, and at 420MHz FSB the RAM is only at 525MHz. Its not the CPU's overall clock limit, as dropping the multi to 6 (from 8) drops the CPU back down to 2520MHz, but doesn't let me go any higher on FSB

Shame, as its totally stable at 420MHz FSB, and is begging to go further.

Guess I'll have to wait and see if a BIOS update solves the issue (and brings back the FSB/DRAM strap options that disappeared from Beta 03 to Beta 04.

On a side note, forcing the BootBlock sector to flash on BIOS updating really does wonders for performance on a clock for clock basis!

Dropped my 1M SuperPi from 19.242s to 18.484s

paradigm · 17 Jul 2007 at 22:10

Right, well its ORTHOS stable right up to 422MHz FSB, but not a single FSB more

Seems that is definately the limit of this chip. Going to try an E2160 as soon as I can aqquire one

EDIT: Its nice to note that my OCZ "SLi" PC8500 is 100% happy to run up to 615MHz at 5-5-5-15

paradigm · 18 Jul 2007 at 16:14

Sourced me an E2160, will give that a go tonight and see if the chip can surpass the current FSB wall. I will also try the BSEL pin mod from 800 > 1333FSB and see if that helps by moving the FSB strap.

Has helped a few guys over at XS forums, one guy stuck at 450FSB managed 466 stable with the pin mod, so here is hoping

paradigm · 18 Jul 2007 at 20:31

E2160's are NOT worth the extra cash over the E2140. Its possible I have a good E2140 and a bad E2160, but given that they are the same week then I doubt it.

The E2140 manages 3375MHz totally stable (orthos proven), will bench 3dmark06 all day long, and sits at 1.45v whilst doing so.

The E2160 just about scrapes 3456MHz (384x9), and not a single 1MHz more, and to do this, needs 1.52v core :eek:

.

I've gone back to the E2140, and the E2160 (that can do 3.3GHz at 1.45v) will get sold.

Ah well, it was a gamble, but it didn't pay off

paradigm · 19 Jul 2007 at 00:55

A couple of degrees hotter on the E2160, but seeing as technically they are the same core, but with different multipliers they "should" run the same.
