E2140 & P5K-VM - Undervolted, overclocked!

Post by zoob » Tue Aug 14, 2007 4:03 pm

This chip rocks!

CPU: Intel Pentium Dual Core E2140 - SLA3J - L711A691 - Pack date: 07/20/2007
Motherboard: Asus P5K-VM - 0401 BIOS
RAM: 2x1GB Kingston ValueRAM DDR2-667
Heatsink: Scythe Ninja Rev. B w/Yate Loon SL12

Had to trim the bracket on the Ninja Rev. B to clear the caps. Look at the paste distribution before I modified the bracket.
Image

I've undervolted and overclocked the CPU.
Image

8x333, 1.2750V set in BIOS, 1.168V load according to CPU-Z.
I've hit a wall at 333, and I can't seem to locate any conductive ink to attempt the BSEL mod to increase the default FSB from 200->266->333.

I have it temporarily setup on my desk using a Phantom 500W, Seagate 7200.7 40GB IDE (w/AAM ON).

This is replacing an Athlon 64 3000+/MSI RS482. Once I get the machine together, I'll make an update in the gallery :)

/wave

i'm replacing my Athlong 64 3000+ as well :D good time to upgrade

got mine yesterday, boot up at 2.96GHz [370*8] at stock voltage, after failed at 380, over voltage doesn't seem to help.

might want to check your fsb/ram ratio if you can't pass 333. this little chips r sweet cookies.

Hey you're right. I had it manually set to 1:1, so instead I set it to Auto.. Booted up 334, 335, 340. Testing higher now :D

EDIT: Damn. It sometimes boots up, sometimes doesn't when it's > 333. Looks like I was lucky when I did a quick test.

EDIT 2: The NB gets really hot, to the point where the onboard video scrambles and Windows crashes. Point a fan at this, or get a discrete video card.

:( gl on that

might try manual but set your ram lower, not sure what options you have on your mobo.

There are a number of reviews showing that the E2140 overclocks quite a bit less than the E2160 although how typical this is is hard to ascertain. Here’s one at Xbitlabs.

i suppose the "better" chips might be marked E2160 but it's really like a lotto. think i saw (might be dreaming..) a pic E2140 boot at 3.2G but E2160 could easily pull ahead with a slower FSB.

i installed windows xp sp2 on my new E2140 at 3GHz (375*8 ) last night, stock voltage (mobo seems adjusting it within a 0.1v range). orthos n 3dmark 2006 didn't make it complain. i'll be testing it tonight in the case. but probably won't go much higher, heck i was even planning to throttle back to 2.8G the night before.

Northbridge is totally holding that setup back.
I swapped in the motherboard and CPU, however a few things:

The supplied IDE cable is JUST long enough for an Antec SOLO and the two upper drive bays. It's quite taut so I'm going to go out and get a longer cable.

Once I put in a 7600GT w/VM-101, I was able to play some CS:Source for about 10 minutes before it locked up. Moving the 120mm fan lower on the Ninja to blow over the VM-101 and NB sink helped it for a few more minutes. I will be getting a Scythe 40mm fan for this.

I have it clocked at 8x233 for now. Plenty fast for regular desktop junk, but I can feel the difference when playing games. No more stuttering TV tuners!

lol u gotta hate that

how your temp now? and which software do you use to check your temp? my E2140 restarted twice playing wow at 3GHz so i backed off to 2.8GHz, 30 min of blended orthos have pushed the cpu temp to 72'C (in coretemp) or 68'C (easytune, gigabyte's mobo utility), with a nexus 120 mm case fan, and ninja stock fan pluged in the cpu fan header. it's really not encouraging and i'm thinking if i should get thermalright backplate kit or try to return it (might be hard here...)

i might try stock cooler again in the case, it's so difficult to work around in a case with a fat ninja in it... took me 10 min to fix the mobo and everything, probably even longer to take it out

I'm not sure what the temperatures were. When I stressed it (Orthos Small FFT) for 10 hours at 8x333 1.30Vcore BIOS it ran at 65C CoreTemp 0.95. I'm assuming it's going to be lower than that :)
i'm thinking if i should get thermalright backplate kit or try to return it (might be hard here...)
Check to see if your bracket is being blocked by capacitors like mine. If it's clearing the bracket, check the thermal paste spread when you take your heatsink off. If it's terrible, grab the kit for sure!

In the SOLO, it was a VERY tight fit with the Ninja, PSU and a 38mm thick case fan. I had to remove the case fan in order to get the top left push in secured properly :P

heya, the clearance/imprint were good before i put it in the case

i think it's very likely due to gigabyte's "automatic system voltage" or w/e, i changed it manual, set vcore to normal, cpu-z report ~1.28v (instead peak 1.4v under stress last night), and neither TAT or orthos (15 min small, 15 min blend) could push my e2140 over 63'C, i could live with that.

Image

now i just need to make sure the chip can stand 2.8G with 1.28v

gl with yours. :D

Thanks for the thread people. I’ve had trouble sourcing an E4400 M0 so when I saw a deal on the E2160 for less than the cost of the E2140 I figured I’d buy it. If I hadn’t read this thread I might well have not thought about it. The 1MB cache only seems to be a major drawback for games which I don’t play anyway.

I’d be grateful if people would post the following data (or at least some of it) to get a picture of these chips, e.g.:

Model No – E2140 (there’s an E2180 due in Q4)
Stepping – L2/G0
VID – 1.325V
Minimum Vcore at stock speed – 1.15V (BIOS or RMClock)
Maximum O/C at stock VCore – 2.4GHz (300x8)
Maximum O/C – 3.2GHz (320x10), 1.4V (BIOS or RMClock)
Stress testing – Prime95, 2 hours
DTS Temperatures – Idle/Prime95 (28/55) - 3GHz/1.3V
CPU Cooling – Ninja+, Nexus 120mm @ 620 rpm
Motherboard – Gigabyte P65-DS3
Power Consumption (Idle/Load) – 60/95W (1.2GHz/1V, 1.8GHz/1.2V)

CPU-Z, CoreTemp, Intel TAT & Speedan should supply all the data needed.

I’ll post details when my E2160 shows up which will hopefully be soon.

Wow, very nice overcklock. Im considering the same setup, but the board doesnt seem to have a DVI output. Is there something like that in the ascessories if you dont mind me asking?

For more E2140/E2160 results, check out this thread over at XtremeSystems:
http://www.xtremesystems.org/forums/sho ... p?t=145328

Perhaps not as much detail as what you'd like regarding minimum voltages, but you can see how fast people are pushing their chips.

Bought a E2140 too. It runs with 3200 Mhz (8*400 Mhz) at 1,34V Vcore. I didn't have the time to do more testing. But I'm gonna try to fill out the information you are interested in smillingcrow.

This E2140 is crazy, 100 % overclocking for 60€. But the 1 MB Cache is really a drawback for folding@home.

So here is my data:

Model No – E2140
Stepping – L2
VID – 1.325V
Minimum Vcore at stock speed – 0,9V (BIOS)
Maximum O/C at stock VCore – 3.140 GHz (390x8)
Maximum O/C – 3.295 GHz (411x8), 1.45V (BIOS)
Stress testing – Orthos, 2 hours
DTS Temperatures – Idle/Orthos (40/60) Speedfan
CPU Cooling – Stock Cooler automatic RPM
Motherboard – Gigabyte GA-P35-DS3

I have to change the cooler, I will do that in the near future.

It sounds as if you have a particularly good chip there. What clock speed and Vcore do your DTS temps relate to?

There is an issue with Speedfan showing incorrect temperatures in some cases due to it assigning TJunction an incorrect value so this is something worth keeping in mind.

You are in a forum about silent pc. ;)

So it would be nice if you also report idle or/and full load power consumption

Most people don’t have a power meter so don’t expect much data on this.
I updated the list of info to include power consumption and also to include GHz/VCore for the DTS data as without that it’s hard to conclude much from it. My E2160 still hasn't arrived. :(

I know, I wanted to include that too but I was to lazy to crawl under my desk and look at the power meter =)

You get the power consumption in a few minutes.

Edit:
139W@ 3080 Mhz load@1,325V
99W@ 3080 Mhz idle with EIST and C1E

87,4W@ 919 Mhz load @0,9V
82W@ 670 Mhz idle with EIST and C1E

Some preliminary data:

E2160
FSB - 200
CPU - 1.2/1.8GHz
idle/load - 52.5/79W (EIST enabled)
VCore - 1.187/1.2V (RMClock)
DTS Temps - 38/59C (TAT), ambient 27.5C
TJunction = 100C (confirmed by CoreTemp)
Prime95 - 1:50 hours
Scythe Ninja Rev A fanless
Nexus 120mm case fan @ ~600 RPM
Gigabyte G33M-S2 (IGP)
Samsung 500GB SATA2, Silverstone 300W fanless, RAM - 2GB 667 CL5

The BIOS allows much lower than the 1.187V that RMClock allows; will test later.
It wasn’t stable at 2.7GHz 1.3V but was at 1.325V.
The motherboard supports Penryn and Speedfan on both fan headers; it only has two though.
The main issue with the motherboard is that the RAM dividers are very limited. With a 200MHz FSB CPU the minimum RAM speed is 667MHz. If I bump my E2160 to 300MHz the RAM is set at 1,000MHz minimum. Unless a new BIOS addresses this the only solution is a pin mod to set the FSB to 266 or even 333; I will try this next week.

Gigabyte boards typically don't support the BSEL pin mods and won't POST.
Neither do Asus nor MSI.
Very few manufacturer's mATX C2D boards have ever supported the pin mod, I think ECS and Foxconn. I'm not even sure if their G33 boards support the pin mod anymore.

The link I gave is referring to pin modding the CPU not the board so it should work with all boards.

Bumping old post.

Yeah I plopped in the E2140 and it worked without a hitch.

I got a great deal on a P35-DS3R (same price as the P5K-VM) so I swapped the board. I'm sitting at a round 3 GHz with less than stock voltage.

E2140 -- L2 rvision
VID 1.3250V
Tjunction 100C

Set 1.3750V in BIOS (F5), loading at 1.312V according to Speedfan and CPU-Z at 80C on both cores with a Scythe Ninja Rev B and Yate Loon SL12.

I stumbled upon a thread about a guy who removed his E2160 and found that it was not soldered: http://www.ocforums.com/showthread.php?t=527553

This could be why the chip runs relatively hot compared to my E6700. I also noticed that the stock Ninja Rev B. mounting system is much tighter on the P5K-VM than the DS3R.

EDIT: What the! I pushed down on the top of the Ninja and then it dropped 10 C. Haha.

I ended up with this setup myself, but with stock cooler.. E2140 + P5K-VM.. runs good at 2.4GHz, about 40C in bios, havent got lm-sensors running in linux 64bit yet...

Folding@home is running at an acceptable 1200-1300ppd, was expecting less :) (1WU = ~32hrs)

I put mine in an old colorbus case from 1997, more info here

I've got a whole vial of silver/ conductive paint at home, give me a shout if you want some (there's about x10000 what I needed for unlocking my sktA sempron :)). Same goes for anyone else.

smilingcrow - what do you think about the G33 board? I've been looking at one of those for my latest "wishlist build". I'm a bit of a gamer but I like the idea of a mATX board for low power consumption.

I like it but it has a number of issues which will put some people off:

The minimum RAM divider for 200MHz FSB chips is 1:1.66 which means that if you overclock by 50% the minimum RAM speed is DDR2-1000. The Gigabyte P35 boards allow 1:1 for all C2Ds.
The north bridge heatsink is fairly small so it might be risky to run a high FSB without extra cooling. The same goes for the budget Gigabyte P35 boards (S3L/DS3L) but not the S3/DS3 and above.
The D-SUB picture quality is poor at 1680x1050 which for me is the only sticking point. I’m struggling to find an ADD2 card to give me a DVI output.

On the positive side there’s:

Power consumption is 51.5W at idle with an E2160 (L2) with more to come with a more efficient power supply and M0 revision.
Speedfan can control both fan headers fully; there are only two though. It doesn’t report fan speeds properly but I have a feeling the newest version may fix this.
My Ninja+ Rev A fits with comfort.
The BIOS is very flexible and allows under-volting to 0.5V.

I don’t think the P35 boards will consume much more power and will be better for people over-clocking a 200MHz FSB C2D. I’m considering borrowing a P35-S3 this week to test this theory.
