E2xxx and E4xxx overclock thread

[aiya24]

all you guys hitting over 3GHz is making me want to go back to watercooling. as much as i love my Ultima-90 but for some reason i still get 60-65c core temps in coretemp 0.95.4 w/ 1.37v under load. my guess is my IHS has bad contact with the core and i don't feel like poppin' the top. don't trust myself with a razor blade

Bit the bullet today and ordered the TT Big Typhoon on Serpent's advice and numerous great reviews. I know the rest of my equipment is capable of a 350FSB, did it dropping the multi for the heck of it. If this E4400 is capable, beware 3.5'ers!

p.s. - Anyone that has one have any advice on exactly how to get it just tight enough? It's a big honkin' thing and I want it to be good and tight against the CPU, but the bolts aren't spring-loaded to keep you from over-tightening like some other HSFs (for good reason...it's freaking HUGE).

been running for a month or so perfectly fine at these settings


Come on guys, i have been able to run this at 3.7, 3.8 with it failing when i do prime 95 on both cores, does fine when i do on only one core

btw: updated info

COME ON GUYS, 4.0 or no balls !

Why did you have to up the ante? If I fry this CPU, my wife is going to kill me!

p.s. - How high have you taken / heard you can take that Vcore without toasting the processor?

 

[24601]

I have never heard of fried CPUs in this day and age

just people scaring your to stop you from greatness imo
OS usually crashes and you get an auto reboot before that
and if you REALLY push too far it just doesnt boot and you need to clear cmos

btw, get a TR Ultra 120 extreme

and dont mill the bottom of it, its supposed to be bulging as it puts huge pressure on the center (where the core is) to make better contact

Thats why SOOOOO much force is needed to get it seated on the mount


btw i used a 90cfpm fan

hope this helps

Do an X pattern...a little bit at each corner until you can no longer rotate the CPU cooler with light force at the CPU fan. The goal is to achieve just enough clamping force to prevent the CPU cooler from slipping when positioned vertically.

I can run my E4300 @ 3.58GHz with only 1.505V in BIOS (1.46 load). Max temp in 85F room is 80C. VTT, NB, and SB at default settings. System is Othos Large stable. To achieve stability with S&M's Heat, I need to bump Vcore to 1.525 or test in <66F room.

High voltage will fry the CPU over time. If you plan to keep the CPU for at least 3 years, then limit load Vcore to about 1.45 and core temp to 75C.

If both mating surfaces are smooth (good surface finish) and flat, then there is no need to apply excessive clamping force. Bottomline...bulging is bad. That's why you need to apply excessive force to achieve adequate heat transfer.

Sizzling!!! :Q

Its all relative. :laugh:

 

[SerpentRoyal]

@ OP,

My number should be 9x 388 instead of 9 x 387.

We may see 9x 400MHz FSB and 500MHz RAM speed if I decide to mod my Big Typhoon to permit direct attachment to the CPU core (no heat spreader). Will only run at this speed if my CPU core under Othos Large mode is under 73C with 85F ambient. No need to push Vcore higher than 1.46V under load.

 

[zach0624]

@ communism, how do you keep the cpu from throttling at that temp since I believe the e4xxx series has a Tjunction of 85C and I thought that if you went over that it would throttle the cpu so I don't see how you could get 97C+, I am a n00b in the area of throttling though so an explaination would be nice. Also I am hesitant of posting aOC with that high of temp.

@ serpent, fixed fsb

 

[hokiealumnus]

Actually zach0624, my E4400 has a 100c Tjunction Max with L2 stepping. I don't have an E4300, but they're probably the same. Especially since Serpent keeps saying he's OK at 73c.

That said, at anything above 85c, as I understand it, the CPU does throttle. I would certainly never take temps that far. To each their own I guess.

 

[SerpentRoyal]

Yes, E4xx0 has 100C Tjunction. Based on my tests, these C2D chips are not Orthos stable for more than a few minutes north of 80C. The general rule is 90MHz core speed for each 0.04V bump in Vcore using Abit IP35-E. The Asus P5B Deluxe will require a little more Vcore.

Core speed is KING but there are also many other variables that can affect real-world speed of a PC. I like to use Super Pi 32M because it represents a real-world number crunching task. Fast CPU and fast RAM will always yield low SP time. That's why I included 32M Super Pi time in my result. The PC is probably 85% stable if it can run 32M SP.

 

[24601]

Hmm, when i OC i generally put the voltage to the highest on every component with it still booting, and then OC to the highest it can go, and then see if its usable after, this is how i got 3.7/3.8, but only 3.6 was usuable, i've also tryed to lower the multiplier and raise the FSB, but every time i do it my computer wont boot for some reason xD

 

[hokiealumnus]

Yea, the E4400 doesn't like FSBs too high. I tried lowering to 8x just to see what I could get out of the FSB. Took less but still significant voltage to the CPU to get it to boot as it did going ahead and upping the CPU speed. From my faulty memory, I think it took 1.425 to boot w/ a 350FSB @ 8x (2.8GHz).

 

[SerpentRoyal]

E4xx0 should run well up to 425MHz FSB. You may have a so so chip, or perhaps there's some sort of interaction between the OCZ RAMs and your overclock. The nominal overclock for these chips is 3.2GHz, plus/minus 400MHz if you include the best and worst.

 

[hokiealumnus]

When my BT comes in, I'll put that to the test. Maybe I need to loosen the timings to 5-5-5-15-2T from 4-4-4-15-2T? Can't wait until I can experiment some more. This whole limited-by-stock-cooler thing is killing me. I don't know what I'm going to do with myself when I've reached the actual limits of what the CPU can do. Overclocking is waaaay too addictive!

I have the Geminii cooler, which is more hype than substance. I have reseated it three times with little improvement in my temperature readings. I don't think it's seated perfectly flat since my readings seem to be a lot higher than others are getting with the Geminii. A backing plate would help as the motherboard warps easily when the heat sink is tightened.

Maybe that's why NewEgg is now offering that cooler FAR... I tend to agree, it seems more hype than anything. My friend has one on his quad-core, and it can't keep it cool enough to run @ 3.2Ghz, it throttles doing anything. I bought one too, not sure now what I'm going to use it on.

 

[zach0624]

@ Communism,
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!

You should be able to go higher with an after market CPU cooler. Vcore is only 1.38. You may want to try a lower NB voltage. A one notch bump should be adequate for 450MHz FSB.
