E2xxx and E4xxx overclock thread

[DAC21]

Ooops! my E4500 did it again.

OK, OK it takes two to Tango and my Abit IP35-E came along for the ride. I thought my overclock runs were over at 3.4 ghz, but with a few drops in Ambient temp (75F) I thought I'd go for 3.509. YES!

3.509 Ghz
Idle / Load 32/72
11 x319
CPU 1.5275v (CPU-Z 1.480)
Orthos Large
AC 7 Pro (believe it or not, it keeps on giving)
Ballistix 2 x 1 GB, DDR2-800 4 4 4 12 (1:1)

Be sure to enabled C1E and EIST to drop voltage and core speed when PC is idling. Congrat on breaking the 3.5GHz barrier.

Sorry about mix up read up and m0 is 100C but it looks like l2 is 85C. Even so I am hesitant to post a oc with a 97C core temp. If you have an OC with a lower temp I will post it.

Zach0624: Sorry I didn't include it in my post, but the E4400 is L2 stepping and has a 100c TjunctionMax. Per the Tom's Hardware C2D/C2Q temperature guide, only the B2 stepping has an 85c TjunctionMax.

"Tjunction Max = 100c (B3, G0, L2, M0 Stepping)
Tjunction Max = 85c (B2 Stepping) "

Just FYI.

Thanks for the thread BTW; it's good to see so many people getting good numbers from these very inexpensive processors. If only the @4x00 series' 2M cache didn't make it so much hotter, I think we'd see even better numbers. Anyway...thanks!

My bad when looking on intel I went by the thermal spec 71-72 for M0s and 62 for L2s. Thanks for the info!

I've been thinking of trying to see how high my E4500 gets with 1.5V but haven't had the time. At what speed did your cpu start needing a lot of volts? after about 3.35ghz I need a ton of volts to increase speed. I'm pretty happy with 3.3ghz but It would be fun just to see how high it can go.

 

[hokiealumnus]

Well, I haven't gotten my BT yet, it comes in tomorrow, but in case anyone is looking for a TIM to go with a cooler they are buying, I would recommend Arctic Silver Ceramique. They shipped from different locations and I got the AS first.

I've never applied aftermarket TIM before so I did a practice run with my stock HSF. Just to see what it would do, I ran an Orthos test @ 3.0GHz (1.345Vcore) that I have in the thread (which is completely stable, it just gets warm under load for my tastes). Previously, I had dropped my machine back to 2.8 @ 1.325(default) just to keep temps down. 3.0 was hitting 73-74 with the stock TIM. After installing Ceramique, I'm running a few degrees cooler 70-71; and that's without AS's advised 25 hour break-in period!

Not to mention it's not electrically conductive like AS5 is at high temps, so if it they get too hot, I can use it on my PWM & NB as well. Two thumbs up for AS Ceramique!

@ OP - Please update. FYI, M0 stepping was incorrect on my previous result, so just delete that.

W00T! I'm a believer. Thanks to Serpent for recommending the Tt Big Typhoon. It's not the crazy results I expected (say, mid-60s @ 3.33GHz), but it's pretty damn good nonetheless. This is in a hot (77F) room too!

I'm actually worried about over/undertightening this thing. Guess that'll come with experimentation. Are these temps to be expected with the included fan?

 

[SerpentRoyal]

Medium speed Panaflow will drop temp by 2C. 3.3GHz is above average for L2 stepping.

 

[hokiealumnus]

Well, above average is good enough for me! Thanks again for recommending this beast. It wasn't bad to install either. Just takes a bit of time since you have to remove the MB. Tried loosening & tightening the bolts a bit, negligible difference. I may try reseating with less TIM. I followed AS's instructions. Felt like a bit much, though I have nothing to compare it with. I'll try to eek a bit more out of it when I have some more time. Until then, above average it is!

 

[SerpentRoyal]

You can press down on the H-CLIP to squeeze out the thermal compound. Put the MB on a firm surface before you do this. I normally apply about 30-40 lbs of down force. Also check your RAMs. OCZs will normally require higher NB voltage. Note that excessive voltage will result in instability.

 

[hokiealumnus]

@ OP, please scratch that last update and add another 100MHz to it!

Applied yet another tip from Serpent and it worked like a charm. Squeezed the HSF with pressure on the back of the MB; I guess there was actually too much TIM. Then I cranked the HSF down a little bit; I think I was being a little too conservative before. Plus, the room cooled off since this afternoon. Not to mention I guess I was very lucky with my CPU purchase; just happened to be built on a decent week I guess. Yay BT!

updated for hokie twice(teaches me not to read to the end of the thread )
BTW nice oc

 

[hokiealumnus]

Thanks! Except for Demented, it appears my CPU is more of a voltage hog than most. Actual running Vcore in Speedfan & CPUz show 1.46 after vdroop & the normal BIOS undervolt (gives less than its set at for whatever reason), so I suppose it's not that bad. May try for 3.5 if the mood strikes, but I'll stick with what I've got for now...presently having a "keep my CPU alive for sure" mindset.

 

[johnnyjohnson]

Don't let this thread die yet, I'm just getting started

I upgraded from an e2160 to the e4500. The chip runs much hotter than my old one, so I tossed the geminii and moved up to a Tuniq.

I've got a real good e4500 on my hands. Maximum frequency I could get was just over 3.7Ghz. http://valid.x86-secret.com/show_oc.php?id=256891 No heavy stress testing, but was stable enough to run super pi - only 15.6 seconds for 1M digits. :shocked:

YMMV, but there's no doubt in my mind that the e4500 series are good overclockers. For those looking at the e4xxx series I'd recommend them. If you're looking at the 2xxx series, I'd recommend the e2180. They tend to overclock better than the 2160s and have the flexibility of a higher multiplier.

I plan to lap the heatsink & cpu this weekend to see if I can get good temps at 3.6Ghz which is what I'd like to run it at. It needs "only" about 1.5V at that speed. I will post back with my final stable results.

 

[SerpentRoyal]

1.5V may be a little toasty. I'm stable at 1.505Vcore with a core speed of 3.58GHz. However, the peak core temp is too hot for my comfort (north of 78C in 85F room). 1.465 is pretty safe for these chips if you enabled C1E and EIST in BIOS (about 1.42V under Orthos Large mode).

System is good if you can pass 2 hours of Orthos Large mode.

 

[itakey]

I have an E2160 on its way with an Abit IP35-E. Anyone have some settings they recommend to get me started? I DO NOT want to overclock it where i'll have to worry about it. I just want a little extra juice in a safe zone. I will be running XP 64-bit with 4GB of the value HP Ram.

 

[zach0624]

wow johnny great oc, as soon as its stable let me know, I should try and see what my chip will get at 1.5V just for fun, maybe it'll hit 3.5 wouldn't keep it that high though so it will last longer on lower volts and I don't need the speed(although ut 3 maxes my 5600+ at 3.15ghz).

@itakey I would get a good after market cooler like a tuniq, artic freezer, or tt120. set fsb to 266mhz and stress test with orthos, it should easily hit that with default vcore (set it manually), then bump the fsb to as high as you can stay stable at.

Thanks for the tips. I purchased this cpu cooler for $1 after rebate
CPU Cooler

So just go in and raise up the fsb, without raising the voltage or anything to the chip yet?

How about the memory? I went with the value HP chips for $10 after rebate, 4 of them. Does this need minor tweaking to get the voltage up a bit?

 

[desolate]

Hey, didn't know if it was to late to add me to the list or not, i'm pretty new here at anandtech

E4300 @ 3.33Ghz
9x371
v1.46850
Speedfan 34-35 idle
Orthos 67 load
AC7 Pro
FPO/Batch # L649H046 (Pack Date 05/01/07)

Don't know if you need any more information then that, but if so just let me know.

Quick question, I'm trying to make it to 3.4Ghz but I'm having no luck at all. I've tried upping the voltage to around 1.48125 and even 1.493 or something around there at 9x378 with no luck. I tried even at 8x425 and my computer then won't boot at all. But using 9x378 I fail orthos around 11 minutes. Do you all think I've just hit the highest I can get with this chip? Would adding more volts to my northbridge or FSB do much? I'm already at high temps with only an arctic cooler pro 7 but I don't plan on keeping this chip for more then a year or two. Thanks.

Set 1:1 memory divider. Raise Vcore to 1.375 or 1.4. Set FSB to 333 and see if PC will POST. That CPU cooler is good up to about 3.2GHz. If you can boot into windows, then raise FSB by 5MHz. Repeat as needed. You'll need to test with Orthos Large mode (1 hour) and Memtest86 to check for system stability. RAM should do 400MHz at 2.0Vdimm.

Drop back to 1:1 memory divider with 2.0Vdimm and 5-5-5-15-2T timing.

 

[zach0624]

updated for me and desolate.

Got to 3.4 with 1.5V and temps still seem good may try for a little higher (My dad's a little weary but I won't keep it with this high of volts until its really "needed"). I'm going to have a busy week so I don't know how long I can work on it

 

[hokiealumnus]

Nice overclock Zach. Mine is having trouble going north of 3.4. Not giving up yet though, just no time to play with it. Good luck!

It is amazing how well these chips overclock! I was thinking of going with a e6750 but they were still over $200 when I built the computer and the e4500 was only $140. For 25% less I was able to reach about what most people were able to reach with there e6750s and p35s.

Vcore for me took a huge bump to get over 3.4ghz and hopefully it won't take over 1.55V to reach 3.5ghz but I'm extremely happy with 3.3ghz and wasn't sure if it could even hit that much (just hoping for 3ghz). I'll probably keep this cpu until quadcores become cheap and then get a penryn and see how it oveclocks.

 

[johnnyjohnson]

I have come to the conclusion that my e4500 is an unusually hot one - as hot or hotter than a quad :frown: I lapped both the Tuniq heatsink and CPU. At stock speed (2.2Ghz) I am getting idle temps of 38-40C and load temps of 50-52C. This is in a 70F room. What's strange is that the default voltage for 2.2Ghz is very low - only 1.1875V in the bios. Something's not right, but I have reseated the heat sink a couple times to be sure. It's the chip.

I've had the chip as high as 3.74Ghz (seems to be its max @ 1.5275V) but it is just one hot sucker. I am tired of fiddling around with it for now, but one day I want to try removing the IHS and try replacing the thermal compound underneath there, or better yet just mount the Tuniq directly on the CPU.

It takes 1.3675V in bios to reach 3.41Ghz (310x11). CPU-Z reports 1.352V with 1.32V under load. At that point, my idle temps are 45C and load temps top out at 69C-70C. To me this is quite warm for that level of voltage. The chip is capable of going to 3.5GHz with the next bump in voltage, but load temps hit 72C - unacceptable.

I hope it's true that temps decrease as the thermal paste cures. I'll keep an eye on them and hopefully will be running at 3.5Ghz or 3.6Ghz eventually. I know the real world difference between 3.4Ghz and 3.6Ghz is insignificant, but that's besides the point when it comes to overclocking

For now, my new rig is as follows:
e4500
310x11=3410MHz
~1.35V
Abit IP35-E
2 Gb Crucial Ballistix @ 930MHz
Tuniq Tower w/AS5

btw I think the thermal paste included with the Tuniq is crap. Temps were higher than with the AS5. It also dried like glue. I had to use sandpaper to get it off the heatsink. I may entertain trying some better thermal compound in the future.

 

[SerpentRoyal]

My E4300 is 73C @ 3.49GHz with 1.465Vcore. Room temp is 85F. With 69F room, temp went down to 67C. I'd say the chip is normal. Don't forget that these CPUs have 100C Tjunction. However, you should limit the peak CPU temp under Orthos to about 73C.
