E2140s are fun!

[stone_cold_Jimi]

Thought I'd grab an E2140 to play with, along with an Abit IP35-Pro. Man, these CPUs are lots of fun for pennies. Mine has a VID of 1.2v, which is a good place to start. Not had long to toy with it, but at 1.28v vcore and pushing Vmch a bit, 400x8 is where I'm at with SPi 1m around 19s. Haven't tweaked the RAM at all yet, which is old Ballistix DDR2-1000 at 800MHz.

I'll post some screenies when I get time. These are the Celerons of C2D lol. Might try it in my P5K3 under the Vapo when I get that set up, see how crazy it goes. Anyone else having a play with these?

My gripe is Intel crippled them by disabling VT. I can't get myself to buy one because of it.

[stone_cold_Jimi]

I'm assuming that these dies are E6xxx with great chunks disabled because they were from the arse-end of the wafer, though I may be wrong. I admit I don't care about missing VT; they're so cheap that I don't care about quite a lot

[tet5uo]

Yeah 100% overclocks are totally do-able on those suckers, and they're so cheap

whats vt?

Unless you are trying to run simultaneous instances of different operating systems, you will never miss it.

[stone_cold_Jimi]

Some 3GHz goodness, look at that vcore. I have a 60mm Delta fan on the NB and another on the RAM, even turned low they're too noisy to sleep through, so end of Orthos session!

And even then, VMWare will still work even without VT. VT is only needed to run virtual 64-bit OSes.

stone_cold, your on M0 stepping which is like G0 on C2D/Q. i have a L2 stepping and need 1.38v to be stable @ 3GHz

i'm happy though and gonna go back to water eventually due to the heat this chip produces. awesome chips nonetheless though

Right, I thought this must be a "low energy" stepping, thanks for the confirmation. I was looking round and seeing 1.325v default vcores and wasn't quite understanding lol.

Kind of wish I'd bought the IP35-E or the Asrock mobo + CPU deal now. That's real old-time overclocking, taking lower end components and getting the value out of them. Part of the reason I'm doing this is to see how cheaply one can comfortably play UT3 (thinking of getting a HD2900 Pro for this).

Stock HSF on this overclock, BTW. No worries!

I just got an E2140 on a P35-DS3L. I can do 8x350 @ stock vCore 1.325V but for 8x375 I need 1.4V. Rev M0, Thermal Specification is 73.2C.

At 3Ghz under TAT full load on both cores, Core Temp reports 61C. Is this too warm for 24/7 use?

i don't think you should worry about your temps.

mine needs 1.38v for 3GHz and under orthos, coretemp 0.95.4 reads 65c on both cores and thats with my Ultima-90 + low speed yate loon. its also been kinda warm lately here in SoCal for some reason and its suppose to be fall .

I have an M0 E2140!

Can't push it though...Damn Gigabyte G31 board and its lack of a decent memory multiplier!

It does 2.6 GHz at 1.2v...slightly undervolted.

Pentium E21x0 chips are the Allendale core, which is natively 2MiB, with 1MiB fused off. There are no longer (as far as I know) any crippled Conroe cores (natively 4MiB), if it's 4MiB it's Conroe; if it's 2MiB or 1MiB and dual-core it's Allendale; if it's a Celeron 4xx it's Conroe-L (single core, 1MiB L2 cache, 512KiB enabled for now, although this is my assumption).

Right, I thought this must be a "low energy" stepping, thanks for the confirmation. I was looking round and seeing 1.325v default vcores and wasn't quite understanding lol.

L2 is the Allendale equivilant to B2. M0 is it's version of G0. Given the difference in clock scaling it seems safe to assume they aren't tweak to the same degree however, the Allendale seems to sacrafice ultimate clock speeds for other factors (presumably yields).

I picked up a E2140 from Microcenter today for $59.99 plus a few dollars tax. I have it running now at 3.2Ghz in my RD600 board. Anything more than 410 Mhz FSB it'll crash, but I can run at 3.2 with only 1.4 volts, anything higher doesn't affect it. This is a L2 stepping.

[Spawne32]

damnit, on both of mine i cant get the past 2.7ghz and i have a M0 and L2 stepping.

Very nice. I wish I could get mine that high. 2700mhz is about all I can get.

Which rd600 board is it?

Did you get an L2 or an M0?

Which Micro Center? (I work at one...lol)

kind of OT, but does the latest Core Temp beta read the temperatures right on the M0 processors? Systool sees the temps as being ~15c higher than everything else...

My Coretemp reads the same as Smartguardian, the default monitoring program for this board.

And even then, VMWare will still work even without VT. VT is only needed to run virtual 64-bit OSes.

It has nothing to do with the OS being 32-bits or 64-bits. VT allows a different type of virtualization, that brings better performance. You could say that is because the abstraction layer is closer to the hardware.

ive got the exact same chip, bought mine at the microcenter in chicago.
anyway i only have an asrock 4coredual sata2 so its limited in overclocking.

with my old ddr i got it to run 340x8 with the 333 divider. and while playing with cpumsr i lowered the voltage to .875 and it was stable. i didnt even know you could run under recomended voltage i found that out by accident.

anyway i got some ddr2 and did the bsel mod to boot as 266. now im running 295x8 with the 266 divider or is it the 333 divider? i dont remember. but cpu-z tells me 295x8 2.35ghz mem 4:3 @ 4-4-4-9 1t. http://valid.x86-secret.com/show_oc.php?id=258670

temps as measured on TAT/Coretemp and speedfan. 25-27 idle and 40 load(speedfan). add 15 to those temps to get the equivalent in coretemp and tat(40 idle / 55 load).

theres a 15 degree diff between idle and load, and between the various programs. intel recommends you do a 15 degree difference on the temps if you use tat on a non intel chipset. i dont know if they meant up or down. but my computer is pretty stable cept for the random bluescreen that i think is related to a failing psu or drivers. so i think the temps are fine and ill just pretend that the speedfan temps are the real ones.

anyone know how to test a psu?

[BlueAqua]

I had a few stability issues at 3.2 Ghz, but I've found 3.0 Ghz completely stable in every single thing I can throw at it, absolutely amazing on my $.99 air cooler.
