Overclocked my E8400 to 4ghz, is this safe to run?

[Markfw]

jaredpace, what aigomorla is trying to say, is that it appears that this persons chip won't do 4 ghz without way too much vcore, so Jag87's advice to give up on an apparently bad chip. I have a bad X3210, that won't do over 3 ghz, and that is with a lot of vcore and a lot of heat !

Jag, the DS4 may be good, but sometimes a little active cooling on the NB and mosfet HSF's is needed at the FSB and speed he is running.

 

[Tempered81]

Yeah, i think Jag is correct in saying you have a bunk cpu. I wouldn't settle there, keep trying different solutions and see if you are able to run 4.0ghz at less than 1.40Vcore. If you cant, be happy with what you have or do like he said and exchange it.

Like zenoth and he both said, your chip characteristics are abnormal.

I'm tired of arguing with Aigomorla. His opinion is that his water cooling setup is a golden sleigh he has a magical key to, and that anyone running air cooling is the equivalent of a homeless kid in a 3rd world country.

Every post of his ends with either, "Oh and i have a sweet $4,000 watercooling rig on my Quad core Benz" or "Jared quit giving wrong advice". This holds true even on off topic threads about things completely non-computer related.

pfft.

edit: based on what mark said, some quads can barely do 3.0 while others easily do 3.5. The same is likely true for your dual core penryn. yours may barely be able to do 3.8 while others can do 4.3

 

[Markfw]

jaredpace, those last 2 sentences go a little over the line I think. He has never insulted any of my air-ccoled rigs. He is an expert, and when his advice is questioned, he rightfully gets upset.

Try to tone down the personal statements, focus only on advice.

Just my 2 cents.

 

[Acanthus]

generally i wont add more than 15% to the maximum stock voltage for air cooling, 20% for water, 25% for sub-ambient.

 

[Tempered81]

Yes Mark, I'm sorry for those two direct remarks about him. Keep in mind it is not his advice that is being questioned here. If you start at the top of the thread and read down, he enters saying, "jared DONT GIVE ADVICE".

Kind of like starting off on the wrong foot.

Jared, I suggest you put some goggles on with aigomorla, he might sound like a bit raging sometimes, but that is how expert and knowledgeable people react to FUD. It's like our pet peeve.

So just take it easy, and accept his corrections. At the same time aigomorla, you should modify your tone towards him because he is new and inexperienced (compared to you), but he is here to learn.

Be nice to each other, make the CPU section pleasant. Don't make me angry, or you know what happens.

I do agree about the NB cooling, but I doubt that his mosfets are in need of anything. This is a dual core PENRYN, it barely sucks any amps at all. The mosfets are probably running 5-8c above ambient, which is plenty good. The NB instead, might need some active cooling.

Thats another thing you might want to try OP.

we're here to help. I think ...



from an objective perspective aigo's advice seems quite sound. don't just do what any random dude on the interwebs tells you to do.


since I have not attempted past 3.6 I will just STFU and watch.

 

[Markfw]

Jag, I forgot about the Penryn, you ar right, but at 445 FSB the NB will certainly be real cause for concern with active NB cooling. My E6300's in S3 boards, all have 120 mm fans pointed straight at them. When I take the fan off, it locks up in minutes, but thats@490, not 445. Still thats a real possible problem area.

*sigh*

i usually wont give out hardware advice unless i know whaat im talking about.

I honestly dont mean to pick on him, I just dont want this OP getting more confused then he is.

Anyhow... OP try to cool the NB down and see if that will allow a slight dip in your vcore voltage.

Also try to put a fan on the mosfet, sometimes keeping those cool to touch will also allow another .05 flexibility.. Thats sometimes!

And definitely pull that board out and prep it for high end overclocking. Basically pull the stock cooling, clean that mess underneith.. can sometimes look as bad as this:

Here is some ideas... however this is off a 680i. But basically get a 60mm fan and get it near the mosfets, like this:

And see if that will give you a bit more headroom. You'll notice sometimes the smallest of things can add up and give you a better overclock.

Also so we can rule the assumption out or prove it correct on bad chip.... Can you tell me your product number on the chip?

It usually starts out with a L(7-8)(A-G)##### You can get this off the side of your box.

Im actually thinkn about TECing the NB on that X38 Swiftech NB sink + 40W tec should do it. I doubt the NB would pull more then 40W so i think aircooled is even possible :T

EDIT: nm.. id have to cool around 70W on the hotside to keep that cold side cool. Blah...

im sorry i just picked this up... i hope this voltage is a typo. Because i know you said dont go past 2.3 which im agreeing with you on. In fact i dont like to go above 2.1 even unless it has heavy cooling.

But 2.6 is running in DDR1 territory. :X

Without trying to add fuel to the fire of this discussion, but rather look for some overclocking education, I'm curious as to why I was able to OC my E8400 to 4.0 Ghz (& seems like it could easily go higher) at 1.368v. I'm new to OC'ng myself, so I'm always looking to pick up information when I can.

I'm curious why the OP is having so much trouble with his vCore. I didn't have to do anything manually to my vCore, the system did it all for me.

This is the system in my sig.

because you have an average chip. thats what most E8400s are doing.

the OP has a terrible chip, and unfortunately there isn't much to do but sell and buy a new one. If he cares about his clocks, otherwise he can just run 3.6 GHz. But thats a shame...

 

[djnsmith7]

Yea, that is a shame. Hopefully he'll be able to make some adjustments & see better results.

well a couple of things..

first off your chip can be a better chip. Also the maxmus is a higher end board geared at high end overclocking, and also long endurance gaming. The counterpart would of been the full blown DQ6.


DS4

vs.
Maximus
http://www.newegg.com/Product/...+ATX+Intel+Motherboard

big difference in cooling. Also i dont think the OP preped his board, so its just faulting from stress. If he takes some time and preps it correctly, he may see a different result. But as JAG says his VID is terrible. My Q6600 G0's has a lower VID. But im also hearing higher VID cpu's can overclock better at higher voltage, so i guess its a mix bag.

But mostly because of my first response, each chip carrys its own overclock potental. They can only get near, never exact. And theres always a chance for a golden egg, or a black sheep.

 

[djplayer]

I run a Gigabyte p35-ds4 ver 2.0 and my e8400 is clocked @ 3.6ghz and the ram is approx 940mhz 5-5-5-15. I'm @ default voltage and is running almost exactly as cool as @ stock temp... I ran it up to 4.2ghz but didn't really feel the difference even though tests show some increases..

ehh.. 3.6 is fine.. I hop it up a little if I could get my ram stable @ 1000+ mhz 5-5-5-15

Prepping the board - pulling off the NB and /or SB heatsinks and applying fresh TIM to them: Do the mobo manufacturers use adhesive TIM on these? Are there any techniques for pulling them off, or is it pretty simple..?

All I did was set vcore to show 1.38v after droop, mch voltage+1, and FSB voltage +1
My ram has the epp profile for the DDR2 1000mhz@5-5-5-15, and works at that no problem.

1.5v isn't worth the time unless you want to fry your chip.

I just ordered the X38-DS4 which will be here Thursday. I also had a RMA request to Asus for my P5E, and they finally got me an RMA number after i have given up on them. lol
So I guess I will end up with both the motherboards that were so hard to choose between

1. I have been playing around with overclocking and am stable at 3.85 with my E8400. I want to try to get to 4.0 also and am going to play around with upping the voltage to the MCH since I am using four 1gb DIMMs. How much extra voltage is safe to add to the MCH? In the post above where it says to add +1, I can't imagine it mean adding a full volt???

2. Also, on an IP35-Pro board, what would be abbreviation for the FSB voltage? How much extra voltage is safe to add to that?

3. Third, and last, I have read numerous overclocking guides, but none that discuss increasing MCH voltage and prepping your board. Where can I find an advanced overclocking guide that discusses topics like the one quoted?
