That was written when?

Were you responding to me?

[mrcape]

There's no viable data. Whenever you track trends you gotta have good data. Good data goes in, Good data comes out. Without a uniform standard to test against, this is more baseless proof of degradation. Factor in the Air cooling folks with 1.4v for 4.0ghz...now your "Control Data" is worthless.

"Official E8X00 Overclocking Database"

Where art thou?

That's what I was asking for, a database if one exists. I have plenty of my own data, and it needs to be compared. I never labeled my findings as "proof" of anything. I'm not here to prove anything, just to try and work towards an answer.

My point about being an early adopter speaks to the fact that you can't be 100% sure about a product until it's had time on the market.

I'm not sure if you're replying to me or just saying this. And I have no idea what your last sentence means.

[Mav451]

Yeah his post was rather confusing. But the 1.4V for 4Ghz part is hilarious. Those aren't good chips - especially when people are using vdroopy boards to do that as well.

PhilDoc - that link isn't working anymore

Yeah the other day. I have read that article and it's great, proper GTL tuning is instrumental in getting high fsb stability.

I was asking the question about when it was written because I'm not sure it applies to the 45nm processors. There is a different set of tables and voltage ranges for these processors.

[PhilDoc]

Read the article myself as it was about 65nm chips. Nice article though.

This is the reason I'm sticking to <500fsb (9x) OCing at the moment. I'm too lazy to figure it out myself, but I'm sure mr.cape has enough data from his own testing to formulate a guide

[mrcape]

I think that your wise to keep it all low for a while. voltages, fsb etc.

. And I have no idea what your last sentence means.

Where art thou? Hmm, based on what I've seen lately from your posts, I'm gonna stay away from you. You seem to want to spar or push and belittle less knowledgeable folks that have ideas to share. I don't wish to participate in discussions like that. I would like to stay on the subject and see a Database built by E8X00 users. I don't get into the side show stuff, I'm 30 years old man I get tired too easy.

Hey man, no offense, I'm not trying to belittle anybody at all. SOmetimes text communication can come off that way, but it's not my intent. I just wanted to clarify that my post isn't being presented as proof of anything. I too want to see more data and that's why I shared mine!

BTW I'm 36 and I hear what you're saying. Let's just keep rolling towards some answers together in harmony.

[Hughyhunter]

To show off a bit... well I think it's good.
Overclocked a 780i board... think I can get more?

[HDCHOPPER]

1.35~1.36VOLTS FOR 4.0 ! Thats more like it nice score too

[mrcape]

One of my chips could run 1m at 1.17vcore 4ghz. They are beautiful chips really, but just please be careful going up. Or at least take notes lol.

Bunch of young guys here huh? J/K... I'll be 51 in about a week.

I ve got this in another thread. But i thought id share it here as well. 1.48 vcore. notice the vDroop? I have it at 1.48 in my bios.lol
700/1000 on the GT's
Compare link in my sig.

why no reports of new intel xeon ?

INTEL Xeon 3110 3.00/1333 6MB BOX for example.....

Now I am having again the same problem as before with P5B Deluxe BIOS 1226...
I set 8*500MHz for example, with proper voltages (cpu 1.352V, fsb termination 1.30V, NB 1.45V) and sometimes, like 3 out of 5, when I get to XP login screen, i type my password, hit enter... and it all slows down... after like 30 second only the background appears, no icons, no tray no nothing... tough mouse is still operating , and the keyboard as well, but still, the only thing i can do is reset....
Sometimes, it enters desktop all right, and I can run anything, prime95 small ffts, games, dvd, it doesnt matter, and it work like a charm, no errors, no freeze, nothing...
Now why is that...?
Like I said it happend to before with BIOS 1226, but guys here on XS adviced me to change back to 1219, cuz' its more stable, and better for OC...
Now same thing happen with this BIOS rev as well...
Any ideas?
Settings are the same, the ones worked well before, now doing the same old

its voltages specially northbridge. i noticed it when Ocing too. try upping =/-nb voltage. found it depends on timings and fsb speed. so if not enought nb voltage it acts up. so try a bump up n see

Maybe because this is a E8400/8500 thread? why would you clog up a thread with a question like that? There are other thread for that question.

Thanks man... I'll take that as a compliment. Well I really just followed some instructions on the overclocks here and as well with the overclocks over at the 780i discussion thread.

The best part about is my temps never went above 45. Right now i'm prime95 a 3.6 with volts at 1.176, will this be enough? I hope! I want this sucker to last at least a good year or maybe two!

[ArCElM]

OK as things have taken a turn for the worse with these chips - I have decided to remain well under 1.4v how does this look, this is about 6 hours stable.





Seem safe ?

Oh man I am so tempted. According to google it's available from some Canadian retail store for $217.

That looks good to me. I have the same clock stored in my bios and it's prime stable at right around 1.3v, very similar.

Did you leave the GTLs on auto with 9x? That's what seemed to work for me with that particular clock. On any 8x or 8.5x, higher fsb clocks I had to set them manually.

It was a good question and I am sure this thread will move along anyways

Degradation findings.!!!

i have been pushing about 1.5v in my quest of 4.5 through my e8400 and i noticed after priming for a while 8hrs++ and then stop and try other settings prime would almost instantly fail unless you increased volts alot more. so i tried shut down, reboot, and even changing settings by a bump only and would still fail. i had the same settings stored on my oc profile in my maximus bios and i simply loaded the settings again and did a reboot. and just like that its stable at the very same settings as before. am still testing for the sake of information to anyone who cares but my oppinion would be that these boards just arent ready for these chips yet. they take a beating specially the northbridge and start acting funny. if someone runs into possible degradation try the chip on another board under similar condition if you have identical boards( if you are a tester lol) and see if my findings are not isolated to me alone. hope this helps someone. but if you notice degradation try load bios defaults and enter settings again. sorry for the novel but had to share.. all hail overclocking!!!!!!

[mrcape]

Hey Nama, that's an interesting thought. Thanks for sharing the info and glad to hear you got your stability back.

For the record, in my case a re-flashed bios and a fresh windows install didn't cure anything. I was really hoping it might, but nope. I do have another P35, P5K-Premium brand new still in the box that I could try, but not another DFI. I'm also going to try a fresh kit of ram tomorrow night.

[flesheatinvirus]

Im still testing my 745A576 as well though I have not found any drop in performance yet after about a month and have been pushing it past 4800 for brief periods. My test system has a killer cooling setup with seperate loops for chip and card which helps but theres more to this Im sure. Im currently at 4510mhz at 1.46v bios,CPU PLL 1.50v,FSB term 1.30v,NB 1.40v,SB 1.05v,CPU-GTL 0.57,NB-GTL 0.61,CLK overcharge 1.00v with the ram at 600 running smooth. Running Line Load Cal disabled works better with this Wolfdale then my Quad which needs it. I just ran this ten minutes ago.
