E2140 overclocking!

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

Nice temps! I was using ceramique with the 120 extreme. Either the heatsink or the chip wasn't flat. My temps were initially higher with compound smeared over the whole IHS.

I removed and reseated the sink with a thin line of compound down the center of the IHS and that improved temps by nearly 10 degrees.

The extreme tends to sit quite loose on the chip too which doesn't inspire confidence. However i find it works well with my e6600. :confused:

Very impressive, glad I have this board on order.

That Abit uGuru thing, are you using it to overclock via Windows?

paradigm · 17 Jul 2007 at 15:39

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.

I've got this CPU with an Asus P5K

Not a bad combo for a tad over £100.

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

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

nice oc pal

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

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

What temp differences do you get between the two mate?

edit: if any

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.

Garyj881 · 19 Jul 2007 at 07:55

Well i cant get above 3040mhz (8 x 380) ive tried 8 x 400 @ 1.55 vcore and it wont boot, i dont think it's the chip thats stopping me either, sure its my mobo.

Im happy with 3ghz + to be honest but seeing most of you getting 3.1, 3.2 and even 3.3ghz is just amazing.

keep up the good work
