e8600 @ 4.5 ghz 600 fsb stable!

[ace80]

Yeah the P5Q3 is indeed a p45 just with ddr3 mem. Well it looks like i've got a lot of dicking around to come then

lol, well I had it at 600 fsb the first day I had it, so it was easy to get it there one way or another, however keeping it stable at that + 4.5 ghz for the processor was what I somewhat gave up on till recently and realized it's a lot more doable than I realized, that last run pretty much proves that...only did a 50 run once with 4.0 ghz and a 50 run at 4.4 ghz and 590 fsb I believe, so even the 4.4 was considerably less than this, especially since it seems the processor definitely easy up to 4.4 ghz then after that you're truly pushing its' comfort zone a bit and you need to get more settings precisely right to keep it happy under linpack.

[dalekdukesboy]

I just realized something...it's even more stable than I thought, I had my memory set at
1200 mhz with 5-4-4-12 timings! So memory might have been the factor after 40 runs...even so...I forgot I still had it set there, got a nice screenshot of what the memory cache is at these settings at least and know it's actually somewhat stable at that...

[ace80]

Yeah i'd loosen them timings a bit just to be safe or change the divider to a lower speed and tighten that way.
You need my ddr2 OCZ Reapers i have just laying around, they'll do 1300mhz+ @5-4-4-8
Topped them out @ 1324mhz 5-5-5-8 although voltage is a bit on the high side

[theorw]

Very nice!!!
U tempt me to try some over500 fsb clock too...Although i dont think i ll hit more than 550ish with x48...

[a_ump]

yea i have the T power P43, n i'm only at 365fsb . I've tried to get my q6600 3.6ghz stable but man there really aren't many bios options. still congrats man!

i think if you god some kaze's and put them in a push pull tandem its help your temps drastically, course there would be no silence in the room and the surrounding ones XD.

Not fair, why so much more for the e8600s? This is what I have to pay for one: http://ncix.com/products/index.php?s...ufacture=Intel
Isn't this better?: http://ncix.com/products/index.php?s...ufacture=Intel
or http://ncix.com/products/index.php?s...l&promoid=1059
yes, I'm fishing for ideas.... ug, the first quad is too pricey...

you did that on what motherboard though? Not sure if it's this memory or the chipset that doesn't like really high speed but I have axeram memory so I rather doubt those reapers should be better, plus what voltage was that on? this was at 1.384 volts, usually for 1200 mhz'ish with normal cas 5 timings I use 2.2 or less...the other thing is did you do any stress or stability testing with that memory at that speed? I've had these up to 1300 or so but had issues with any stability much over 1200 for whatever reason...

I paid 50euros for a 8400 2nd hand!Am i good???

[dalekdukesboy]

ok, I'm still working at this, I WILL hopefully post a 50 run linpack stable run tonight

[dalekdukesboy]

tref....changed that setting, it was my memory holding me back! refresh rate was too short, this all but tells me there's more definitely in store...4.52 ghz 50 runs is now my new reality

[dalekdukesboy]

man, losing steam on this thread! guess I'll have to come up with some miracle results to renew excitment lol, I thought the 50 runs was it...hmm ok I'll keep working at it

[a_ump]

nice job man, haha n all threads lose steam eventually XD. none the less i still find your clock speed amazing. and 2400mhz FSB stable. How high have you managed to boot up at regardless of stability in linpack?

[Paulenski]

nice man, I'm bit stuck as i'm not too familiar with all the little garble of clocking. Been able to overclock my E8400 to 3.71, altho anything higher it for windows, I figured it might be my ram, I need to get 1066mhz.

[dalekdukesboy]

about 630 fsb is the highest I can boot at...it tries to boot into windows at 640 but nothing will get it there yet so not sure if it's my memory, northbridge, or possibly the cpu just doesn't like that high of an fsb...but at some point I'll get some other memory to fool around with and maybe at some point another cpu to get a better idea of what the limiting factor is...and around 5 ghz was the highest cpu speed I got but that was only a couple lucky times and it was extremely unstable and fidgity...

[PolRoger]

Very nice Tpower overclocks! This motherboard was my first p45 chipset board after switching platforms from AMD socket 939. I'd like to know a little more about the BIOS settings on what you consider to be your optimal high fsb overclock? What RCOMP are you using? and...NB/VTT etc. Your thread kind of makes me want to get mine off the shelf to test again. I still have a pretty decent e8400-E0. I found that compatible ram can make a big difference in achieving big fsb. Seems like your Axeram is a great match.

[dalekdukesboy]

thanks...I use mem settings 2 or 4...I keep forgetting which in which instance but others don't work, and axeram seems to like the board but it does seem not to like going 640+ no matter what I do...I had it boot at 620 fsb and 4.96 ghz the other day but I had to reinstall windows before that and didn't have any way to capture the screen shot! Now of course I retried it and no luck...but I really need some better cooling for some of this craziness I'm attempting, just on a really tight budget and even several fans can add up...anyway my fsb voltage is 1.39 as well as the chipset voltage, I also have the skew on the cpu set to 700 and the skew for the chipset at 500...if I lower them much more I don't even get a boot so seems to make a big difference. VTT is core 0 .63 and core 1 .67...chipset is .58 or whatever the lowest setting is

[dalekdukesboy]

this is my latest craziness....didn't get them on the same screen but the super pi was done with those settings...with some tweaking I may be able to beat my old 680i's top time of 10.359 I believe it were at 5.018 ghz with tight mem timings with a 10x multiplier...seemed a very good super pi run for "only" 4.933 ghz plus I just love the high fsb with it as well. Just so you all know I'm truly a crazy overclocker, this is with my TRUE/air setup and I even typed and uploaded all this with those settings! lol.

[dalekdukesboy]

bumpety bump bump in the road?

[smipuno]

How great your info is!But Can you give some more sample questions and answers.I really want to get more info about this topicIt really useful for me. Thanks.

not sure I understand your post whatsoever...great info but ask/answer more questions? ok...next time I plan to post is with some smoking fast run to trump all others so far but not any questions or answers

[Bjorn_Of_Iceland]

so how is it? 3 months of 4.5ghz.. is it still stable?

[dalekdukesboy]

yep, not even an issue of keeping it stable, I've had it up to 4.52 ghz and it tested stable with same voltage so I probably will see if I can push a little further and see what the true limits are plus that'll give me an idea of how close to the "edge" of stability I am with current settings but obviously I have at least a little bit of leeway yet.

Veeery nice. Youre having me thinking if I should get this or the Q9650.. (which I doubt will reach 4.5 on a P35)

yeah, you should get a cheap p45 and have a ball, not sure if you can get stuff from newegg.com from where you are but often they have open box boards there for cheap such as the one I have...currently I'm eyeballing p55 i7 for a build and checking out ebay etc and newegg for the cheapest way out with components, and I think I can get a ridiculously good system together for fairly low dollars if I'm patient and shop around, this board I got for 85 bucks as an open box and it's obviously done all I want and then some...
