<Overclock>E2140 temp problems

[wowempire]

Hi ! I want to overclock my e2140 and i have some temperature problems.. my cpu is running (without any overclock) at 45-46 degrees IDLE and 65-70 full load .. IT'S TOO MUCH . Any idea ??? I have stock cooler , stock voltages , no overclock. YOU THINK THERMAL PASTE WILL FIX THAT PROBLEM ??

CPU SPECS :
CPU : E2140 1.6 ghz dual core
MOBO : BIOSTAR 945GC MICRO 775
PSU : DELUXE 450 W
GPU : Nvidia geforce 6800GS
RAM : 2GB ddr2 667 mhz

70 under load is not to bad,
make sure the stock cooler is clean,

Temps are fine, nothing to worry about.

 

[Ares202]

Why are you overclocking? If its for gaming your likely to be limited by your GPU/RAM more than anything

Geez! Hadn't seen anyone mention that processor for a few years!

Back in '08, I picked up an E2140 and an E2180 for ~$80 to $90 each -- retail box.

Some people were able to OC those suckers to over 3Ghz. I didn't push them that far, because the mATX motherboards (same model, two PCs) had limited BIOS features.

It seemed to me that locking the voltage just a notch above the stock value (can't even remember what it was) -- I was able to OC to at least 30 to 40%.

We used the stock Intel coolers. However . . . I lapped both the IHS and the heatsink base, and I THINK I recorded a reduction in load temperature of just short of 10C. And if that's some . . . exaggerated memory . . . 5C was the minimum improvement.

For the lapping: get all the nickel-plate off both IHS and HSF base. Not wanting to get a nickname for my chronic promotion of a certain TIM -- the IC Diamond paste also reduced the temps a couple C degrees. [So . . . call me "Mr. Diamond" or "Mr. Sparkles." I'll live with it.]

And fact is -- even better -- use the Coolaboratory Liquid Ultra or something like Indigo Xtreme. No risk there -- for the processor investment! Better than diamond paste, too!

The simple answer is that those 65nm (boy, that was a while ago!) CPUs ran pretty toasty.

I had a paid of OC'ed E2140 CPUs in P35 boards, running as high as 3.2Ghz. I was using CoolerMaster HyperTX2 coolers, with heat pipes and 92mm fans. Even with those, they would run 85C under full Prime95 load.

Really -- I think I stopped increasing the CPU speed of the E2180 when it was around 2.66Ghz. Maybe it was 2.8-something. I can't remember. I don't think the core temperatures went over 60C on a warm day -- or not much over that. I seem to remember "high-50's."

conroe runs hot, but nothing to worry about. the chip is solid. OP temps are fine, my E6600 was the same.

E2xxx should be able to run at 3GHz or more just fine,
the main problem was getting there because of FSB/PCIE/ram divider limitations from lower end chipsets/motherboards

U SURE ? Some ppls just worry when their cpus temp get over 50-55 in full load . Remember i didn't OC'ed CPU , and i want to Oc it...

SO .. i want to overclock it to atleast 2.0 ghz , i saw a lot of ppl have oc'ed it to 2.5-2.8 easily , but i cant even get over 1.72 GHZ , when i set fsb to 230 or more , computer won't boot , even i change voltage ( +0.05) .. ANY IDEA ?

SO , u tell me to buy Indigo Xtreme / Collaboratory Liquid Ultra ? In my country that cost a lot .. like 45 dolars.. and my cpu cost MAX 30 dolars ..

Ah .. 65nm i have a 64 x2 4200 TOO , with a tehnolohy of 90 nm and it didn't HEAT like that.. He run at 2.52 ghz ( 2.2 default ) at 65 full load p95... and that 65nm runs like 75 in prime 95 .. or better ( i didn't ever tested it for more than 10 min .. in 10 min it reach over 75..)

when you overclock the FSB it affects many other things, you need to make sure your memory can handle the higher clock, and if not use a lower setting divider/multiplier

230 * 3.33 (default for 667 memory and 200FSB) = 766
you should set your memory to 533 if you see that option, and manually set the default 667 timings probably.
230 *2.66 (default for 533 memory and 200FSB) = 611 (still under your memory default clock, so you know memory is not the cause of instability, as long as you use the timings for 667 and not 533)

Timings are "AUTO" , memory frequency is 667( now ) but i tried with 400 and 533 too .. same problem . The fsb multiplicator is 8x now , and i cant change it from bios.

I cant find a answer to my question [ Why i cant go over 230 FSB even with + 0.05 voltage or by lowering ram frequency ] even on that HUGE FORUM?

Hi! I want to overclock my e2140 to atleast 2.2 GHz and i'm gettin' some troubles. I cant go over 230 FSB. I tried +0.05 V, still no boot, i tried changing memory frequencies ( 667 - 533 - 400 ) still dont boot. Any ideas ??
BTW i cant move multiplicator from bios. (it isn't any feature to change multiplicator)

I can't really say with your biostar board. It was fairly easy for us with the E2140 and E2180 on Gigabyte mATX boards with bare-bones BIOS. One merely set the voltage at what was measured/reported in BIOS with the voltage set to "auto." It was something like 1.31V -- but YMMV. I think the FSB (and therefore, RAM speed) had to be set with RAM at 667 or FSB at 1333. I think what you're claiming as FSB is the CPU "FSB" speed, which should be 333Mhz to get what you want there.

I can't even adjust the DIMM/RAM voltage on the mATX boards, but only the speed and timings. So we just bought DDR2-667 RAM for those systems.

I thought the processor had a default multiplier of 9 which is otherwise locked, although I think it could be set lower. But lower isn't the way you want to go. So the only way you're going to overclock those E2xxx CPUs is to boost the front-side bus -- probably from a stock setting of 200 CPU -- 800 FSB, to 333 and 1333 FSB. Of course, that would put you at 3Ghz.

Instead, you could shoot for 266 and 1066 FSB, set the divider CPU to RAM ratio at 4:5 and run the RAM at its spec DDR2-667 speed. I'm a bit hazy about the ratio -- either 3: 4 or 4:5 -- but we were able to do it in such a way that CPU ran at 2.4Ghz and RAM at DDR2-667.

So, i cant overclock it on that motherboard ?

I cant go over 230 FSB , u understand .. ? How to go for 266 or 333 fsb , if i set 230+ FSB pc fail to boot . U want to go for 333 fsb or 266 , how to do it if i cant go over 230 ? i'd like to run that e2140 at 2.2-2.4 but i cant go over 1.76 ( 220x8 )

I didn't say that. I said I'm not familiar with either the board or its BIOS.

Look in your BIOS for the following things:

The CPU multiplier -- which you noted is there.
The CPU base speed -- which I think you also observed: default 200 Mhz
for an FSB speed of 800 Mhz, 266 gives 1066 FSB
and 333 would give 1333 FSB

"Ratios" or "Ram dividers" in a menu -- should show options like 1:1, 1:2, 3:4, etc. etc.

The RAM speed setting: As you noted -- options of probably 400, 533, 667, etc.

You want the overall FSB speed to be 1066 instead of 800; but you want the RAM to run at 667 instead of 533. So you need a CPU-to-RAM ratio that reflects the ratio of 266 to 333 (half of 667). Probably . . . 4 : 5.

It looks to me like you have an Intel chipset -- maybe P45? My Gigabyte boards used NVidia 610i chipset. But the respective BIOS's would have similar features for the same processor.

To sum up: with the right cooling (and per VirtualLarry's posts here), you might be able to get the processor OC'd to 3.0Ghz, or 9x333 = 2.97xxx Ghz. But -- with the right cooling -- it will get hot.

So try instead for 9x266 = ~ 2.4Ghz

With the right divider ratio, you should be able to run stock DDR2-667 RAM modules at that speed -- 667 Mhz. Our own experience showed that for this particular overclock -- to 2.4Ghz -- you didn't need more than the reported stock voltage or VCORE.

My Gigabyte boards were very primitive, as I said. I can't set the DIMM or 'RAM voltage; can't set the CPU-VTT voltage, etc. etc.

Also -- as I said -- we had both the 2140 and 2180 processors -- the difference being the CPU multiplier. I suggested here it was 9, but this is all from my memory -- I'm not sure. If it was 8, then you'll shoot for a lower overclock than 2.4 Ghz.

I cant go over 230 FSB , u understand .. ? How to go for 266 or 333 fsb , if i set 230+ FSB pc fail to boot . U want to go for 333 fsb or 266 , how to do it if i cant go over 230 ? i'd like to run that e2140 at 2.2-2.4 but i cant go over 1.76 ( 220x8 )

I understand your frustration. If I had your BIOS screens in front of me, I'd have a more definite idea of what you can or can't do with the hardware.

So -- your multiplier is 8 -- not 9, like it may be with the E2180. If you could get from 200 to 266Mhz for the CPU base speed, then your OC would be about 2.17 Ghz.

I'm just suggesting here that your problem of getting beyond 230 base speed could equally be due to your RAM settings. Somewhere in the BIOS screens, I "imagine" options for dividers or "CPU-to-RAM" ratios. I think you'd want to choose 4:5. On the other hand, there might be a menu of RAM speed choices -- 533, 667, etc.

What you need to end up with here: a CPU base speed of 266 and effective RAM speed of either 533 (1:1 ratio) or 667 (4:5 ratio).

With the right motherboard, the right settings -- you should be able to OC the processor with a base clock of 266. The processor should be easily capable of that.

I feel clueless about your motherboard. The mATX boards I bought were low-priced budget models, and the BIOS features were minimal. But we didn't have a problem with it . . .

I have only cpu speed , cpu voltage , ram voltage , pci-e clock , memory frequency , i dont found multiplier or RATIOS or RAM DIVIDERS..

I had one of those, stock cooler is terrible but enough for 2.8-3ghz, a cheap aftermarket cooler will do wonders for noise and temperature.

Your thermal paste is prabably dry, those chips weren't soldered so you can delid them with relative ease.
Wish I knew about the thermal paste under IHS at the time when I bothered doing a lapping job, never got past 3.2ghz on my e2160

I wish Intel still sold cheap overclockable pentiums, 1.8-->3.2ghz was such an awesome value :biggrin:
